The high-efficiency thermal conductivity of CNC machined aluminum heat sink is the decisive factor for maintaining good heat dissipation and the most ideal medium for heat energy conversion. The characteristics are: less time, fast heating, high efficiency, light and smart, and easy to process. For radiators of the same specifications, the weight of aluminum profiles is 1/3 of that of steel radiators. CNC machining of aluminum heat sinks, and other materials which have more advantages: small number of rapid prototyping, such as energy saving, decorative, price, weight, etc., other. The CNC machined aluminum heat sink is the lightest among a variety of radiators, and it is easy to transport and install. At the same time, it has good thermal conductivity, large heat dissipation, fast heat dissipation, and high metal thermal strength. Because it is machined and formed, it can be machined into various shapes of radiators, so the appearance is novel and beautiful, and the decoration is strong. Since aluminum oxide is the best protective film to produce after aluminum oxidation, it can prevent it from further oxidation, so it is not afraid of oxidation and corrosion, and its moderate price is very popular among working class. With the rapid development of electronic technology and the increasingly widespread application of electronic products, aluminum alloy electronic radiators have become indispensable parts of electronic components. Aluminum alloy uses pure aluminum or aluminum alloy as raw materials. Heat sinks with different cross-sectional shapes can be formed through processes such as smelting, CNC processing, and extrusion. Then, it can be processed in

File#1 OSRAM_LED_front_projector.bmp (84.4 KB) , download : 1 Driver technology from OSRAM i ( http:// ) is integrated into the first full HD home cinema projector with an LED lighting system. RAPCUR10 LED drivers enable LED front projectors to produce razor-sharp images of unparalleled quality. With a resolution of 1,080p (1,920 x 1,080 pixels), a light intensity of more than 500 lumens on the projection surface and an extensive color scale, the full HD LED projector produces a far higher image quality than traditional devices thanks to the RAPCUR10 LED Driver from OSRAM. Moreover, the shock-resistant LEDs have a lifespan of more than 25,000 hours which means that the usual change of light sources in the projector can be dispensed with. The driver has three channels (for red, green and blue) and works in real time in the projector to process the complex control signals responsible for the exact control of the LEDs and thus for the high image quality. For the first time, OSRAM is using an FPGA (Field Programmable Gate Array) which facilitates exceptionally fast and accurate signal processing. The high LED currents of up to 30A and the very short switching constraints demand high switching speeds. The RAPCUR10 driver facilitates switch-on and switch-off times of less than 1μs with currents of 30A. The LED driver can also supply 255 gradations of current.

Santa Clara, Calif. - Catalyst Semiconductor, Inc., a provider of analog, mixed-signal devices and non-volatile memory, has expanded its LED driver lineup to introduce new products for the large-screen LED panel market. The new CAT4016 is a 16-channel, constant current source LED driver designed for billboards, advertising subtitles, meters or other large-size, general-purpose indoor and outdoor LED displays. The CAT4016's LED channel maintains a steady current state at output voltages as low as 0.4V (when the LED current is 2mA to 100mA), which allows for higher power efficiency in application designs. The LED current can be set by an external resistor. A high-speed, four-wire serial interface with up to 25MHz frequency controls each LED channel through a shift register and latch architecture. A separate serial data output pin allows multiple devices to be used in series via the same serial interface. The CAT4016 also features thermal protection that allows the device to turn off the LED output when the die temperature exceeds the allowable limit. As a replacement for similar products from Macroblock, Toshiba or other vendors, the CAT4016 offers a wider variety of packages to choose from, including 24-pin SOIC, TSSOP, QSOP and TQFN packages measuring only 4 x 4mm. Features 16 channel constant current source Serial interface up to 25MHz Applicable LED current range is 2mA ~ 100mA LED current is set by external resistor The minimum differential pressure when the LED current is 30mA is 300mV

When operating a machining center, it is necessary to understand the safe operation specifications of the CNC machining center in advance. This is not only a need to ensure the safety of personnel and equipment, but also a need to ensure that CNC machining can work normally, achieve technical performance, and give full play to its processing advantages. So what is the safe operation specification process of CNC machining? 1. Before booting (1) Wear labor protection supplies and do not wear gloves to operate the machine tool; (2) Read the operating instructions of the machine tool in detail, and safety accidents before being familiar with the operation of the machine tool; (3) The operator must be familiar with the function of each button and operation precautions; (4) Pay attention to the warnings on the warning signs of various parts of the machine tool; (5) Install lubricating oil and hydraulic oil in accordance with the requirements of the machine tool manual; (6) The tools around the machine tool should be placed neatly, so that they can be easily placed; (7) The protective door of the machine tool must be closed before adding. 2. At work (1) Civilized production, concentrated energy, and put an end to abuse and fatigue operations; bantering, chatting, sleeping and leaving the post arbitrarily; (2) When the machine tool is in the state of temperature and electricity, the

MaximIntegratedProducts introduces the MAX16821 high-power, synchronous high-brightness LED (HBLED) driver that responds quickly to current pulses and is the first driver to drive a common anode LED. The device's fast-current-responsive LED technology is currently patent-pending, meeting the stringent requirements of projection applications, and therefore requires very fast LED dimming for forward projection, rear projection TV (RPTV) and pocket projectors. The application is very good. In addition, the MAX16821's unique and innovative driver architecture enables a common anode configuration of HBLEDs, enabling true and efficient thermal management and reducing system integration and installation costs. The MAX16821 features a unique pin configuration capability that allows the device to be configured for either synchronous buck or synchronous boost mode. Synchronous buck and synchronous boost mode allow LED drivers to operate at very high efficiencies, such as high-power applications such as automotive exterior lighting and emergency lighting systems that are particularly power-hungry. The wide switching frequency (125kH to 1.5MHz) allows small inductors and filter capacitors to be used in extremely space-constrained devices such as pocket projectors. For systems that require multiple drivers, the MAX16821 also features a 180° phase-delayed clock output that controls another LED driver that is out of phase. This solution reduces LED current ripple, which reduces the size and cost of the input and output filter capacitors. The MAX16821 operates from 5.4V to 28V and has a built-in 0.03V LED current sense voltage for lowest power consumption (other current sense voltage versions are also available

DC/DC converter is a component that converts DC (direct current) to DC (direct current), specifically a component that uses DC (direct current) to convert voltage. Electronic components such as ICs have different operating voltage ranges, so they need to be converted to corresponding voltages. converter that generates a voltage lower than the initial voltage is called a "buck converter"; a converter that generates a voltage higher than the initial voltage is called a "boost converter."

LED driver IC manufacturers have accumulated to expand their product lines, and this year they will strengthen their LED lighting field. They will actively introduce new products and strengthen their product lines. For LED architectural lighting applications, the accumulation will also officially launch three channels of new 40V built-in power management functions. Constant current LED driver, mainly LED architectural lighting, LED curtain lights, LED light strips, LED signage advertising characters, LED neon lights and other applications. Accumulation shows that the company currently has more than 400 display customers in the world, and some of them have gradually developed their lighting products. This has the development advantages of accumulating in the field of cut-in lighting, plus the company's LED current control. The technical capabilities will also continue to introduce corresponding products to grasp the trend of the lighting market. It is expected that LED products will be launched in the near future. With this new three-channel constant current LED driver, the accumulation shows that this product is mainly used for exterior photo wall of architectural photos, as well as the curtain-type products commonly seen in China. In addition to rich colors, it emphasizes support for longer transmission distance. In addition, this product also provides clock recovery function to ensure signal integrity after long-distance transmission, which is quite suitable for LED landscape lighting applications. In terms of market layout, the accumulation shows that this new product will be widely promoted to the whole world. In the initial stage, it will mainly focus on the mainland China market, mainly because it has accumulated a good foundation in the local area and the local government supports the development of related LED lighting. . Accumulating in 2009, we are optimistic about the fast-growing LED lighting ma

In recent years, the market for high-brightness light-emitting diodes (HB-LEDs) has grown rapidly, and LED performance (efficacy, in lumens per watt or lm/W) has more than doubled, making it more suitable for many new applications, such as our handheld flashlights. Many revolutionary new products can be found in applications such as architectural lighting and street lighting. But LEDs are still facing challenges when they are more cost-effective than incandescent and compact fluorescent lamps. In fact, for many applications, the challenge of powering HB-LEDs based on a wide input voltage range is involved. This is especially true for general lighting applications such as track lighting, which use a 12 Vac or 12 Vdc power supply that can be loosely regulated. However, LEDs need to be driven by a current source rather than a voltage source because the forward voltage (rated 3.4 V) of the HB-LED may vary by more than ±20% depending on process tolerances and temperature. In addition, in terms of the current lumens of a 1 W warm white power LED, typically 3 to 4 LEDs are required to replace the light output of a 20 W incandescent lamp. To achieve predictable and matched brightness and chromaticity, it is also necessary to drive the LED at a constant current. From a architectural point of view, the buck-boost topology meets this requirement, but it is not as common as a standard buck or boost topology. But with a thorough understanding, the buck-boost topology can also provide numerous advantages for cost-effective HB-LED lighting applications where the input voltage (Vin) overlaps the forward voltage (Vf). Reference design overview This reference design document describes the carefully constructed and tested GreenPoint® 1 W to 5 W LED driver solution for MR16 LED replacement applications. This reference design circuit is suitable for driving HB-LEDs in a variety of lighting applications, but is sized and con

At present, there is a big difference in market forecasts for high-brightness LEDs (light-emitting diodes). Although the forecast data is different, the trend is clear: the high-brightness (HB) LED market is growing at an alarming rate. Some forecast data have a compound annual growth rate of 15%, while others have a compound annual growth rate of 35%. In 2007, LED lighting in the automotive sector was in its infancy, with sales of US$670 million, but is expected to grow at a compound annual growth rate of 15%, reaching US$1.2 billion in 2011 (1). If non-automotive applications are taken into account, the compound annual growth rate is close to 35%, and by 2011, the total high-brightness LED market is likely to easily exceed $2.5 billion. What drive is this high growth potential? First, LEDs produce light 10 times more efficiently than incandescent lamps and almost twice as much as fluorescent lamps, thus greatly reducing the amount of electrical power required to deliver a specific amount of light output (in lumens). Second, incandescent lamps need to be replaced after 1,000 hours of use. Fluorescent lamps can last for 10,000 hours, while LEDs last for more than 100,000 hours. In most applications, this allows the LED to be permanently embedded in the final application without the need for an attachment. Examples include display screens for car bodies or LCD screens for HDTVs, as these LEDs do not need to be replaced during the life of a car, HDTV or sports stadium display. Third, LEDs are orders of magnitude smaller than other lighting products, and the form factor can be made very flat so that they can be permanently embedded in automotive interior and exterior applications. In addition, countless colors can be achieved by using red, green and blue LED configurations. Finally, the LEDs are dimmable, and their turn-on and turn-off times are fast and undetectable by the human eye, which greatly improves the backlighting of HDTV

A simplified control scheme built around an optimized HB-LED driver results in rapid start-up for good dynamic brightness control and other advantages, writes Peter Tod. High-brightness LEDs are being widely adopted into luminaires for the general lighting market, with a myriad Of possible applications; commercial/retail downlighting, industrial, architectural, external and emergency back-up lighting to name a few. In the effort to produce more lumens in these applications, the LED driver requirements are becoming more onerous as LED currents increase. Many applications, the typical LED currents range from 350mA up to 1A, however, some of the latest LEDs require anything up to 3A. In addition to the higher current requirements, efficiency improvements are becoming mandatory, for example through Energy Star standards. Size is often important and of course cost is always critical. To address all these requirements requires driver solutions that utilized innovative switching architectures. Figure 1 The majority of LED driver solutions available on the market today are based on standard voltage-regulator architectures. Typical solutions, for example using a fixed-frequency, current-mode-control buck converter (see Figure 1, are far from optimum. The control schemes tend to be overly complex, often having two loops: an outer-loop to regulate the current control (set by R3 in Figure 1) and an inner-loop to provide the peak current control. Components (R2 & C5) as well as having the additional overhead in the silicon, which impacts cost. An output capacitor (C3) is often required, not necessarily to reduce the current ripple through the LED, but simply to ensure the control loop is stabilized correctly. With a carefully considered control loop, this output capacitor can be omitted. Most problem is that brightness control is difficult to achieve. Most solutions rel

Analyze the flow and temperature of the heat sink surface. The plate-type heat sink is composed of independent and parallel oil flow channels, and each channel has three connected small channels. The overall length of the sheet is a simplified slice-type heat sink model. The simulated data is exported to obtain a temperature distribution cloud diagram. In the horizontal line, the viscosity increases from the middle to the two sides, and the viscosity in the longitudinal direction increases, which proves that the speed of the oil in the oil passage decreases from the middle to both sides. From the map oil temperature distribution gradually decreases from the middle of the oil channel to both sides, isotherm is a downward convex curve, and in the longitudinal direction, the temperature is gradually decreasing. Infrared wall temperature analysis. The infrared image of the top surface of the heat sink is taken as the following figure. As can be seen from the figure, the temperature decreases gradually from the top to the bottom, and at the same level, the middle high and low sides tend to be low, but in the middle Below both sides of the oil gallery, this is due to the internal structure of the actual fins, and the oil coming out of the upper collection tube is divided into two, most of which flow into the oil channels on the middle side. The length of each flow path increases from the middle to the two sides, so the resistance increases accordingly, so a temperature cloud appears. It can be seen that the simulation is basically consistent with the experimental results. From the simulation and infrared cloud diagrams, it can be seen that most of the oil flows through the middle oil passage, and the flow rate is fast. Not only the flow on both sides is small, but also the resistance is large and the oil flow rate is slow. Although the heat dissipation capacity on both sides is good, the overall heat dissipation not effectively. The figures and graphs a

The CFD simulation does not consider the contact thermal resistance between the components of the heat sink; there is an error in the assembly process of the heat sink and the measurement accuracy of the thermocouple in the experiment. It can be said that the experimental data confirms the correctness of the simulation results within the error range of simulation and experiment. Therefore, experiments and theories have shown that the use of drainage holes has a significant improvement in the performance of the heat sink based on the chimney effect, that is, the heat dissipation is further reduced under the condition that the COBLED operating temperature has little influence (about 2 ° C). The weight of the radiator (the weight of the radiator example is reduced from 1157g to 1010g) improves the overall performance of the radiator. For the street lamp using COB-based semiconductor illumination source, the COBLED's illumination axis is 60° from the gravity direction [3], and the chimney-based finned-heatsink structure with drain holes is proposed and calculated by using Icepak. The fluid mechanics simulation software studied in detail the influence of the shape, size and distribution of the drainage holes on the quality factor Q of the radiator. The simulation results show that for a COBLED with a surface area of 4cm2 and a heat of 50W, at a maximum temperature of less than 52 °C, two chiseled holes with an area of 15 cm2 and a central symmetry of the light source will be formed on the heat conducting plate. The weight of the radiator is further reduced by 15%. The simulation results were verified by experiments. When the COBLED injection power is 80W, the weight of the heat sink is reduced from 1157g to 1010g compared with the traditional chimney-based heat sink. The COBLED substrate is relative to the ambient air. The temperature rise increased from 35 ° C to 37 ° C, which is basically consistent with the simulation results. The

CNC machining technology is the basic technology of modern advanced machinery manufacturing industry. CNC machining also shows great advantages in modern production. 1. High efficiency in numerical control processing; The use of CNC machine tools can increase productivity, and generally can increase production efficiency by 2 to 3 times. For certain complex parts, the productivity can be increased by 10 times or even higher. Some CNC machine tools have multi-steps and automatic tool changer, so it can realize multi-purpose use of one machine, which not only improves the production efficiency, but also saves the storage space. 2, CNC machining accuracy, suitable for diversification and small batch production; For modern manufacturing, CNC machine tools are ideal for parts with complex shapes, precision, and small batch sizes. One of the main problems faced by parts processing is the contradiction of high precision, diversity, and small batch size. The ordinary ordinary machine tool cannot solve this contradiction at all. Therefore, CNC machining is very suitable for parts processing technology in aviation, aerospace, electric power, transportation and electronics manufacturing. 3, CNC system has great flexibility due to software control; The prominent advantage of modern CNC machine tools is that they can perform high-precision machining and diversified machining, and can completely replace other processing methods. Since the CNC machine tool is automatically processed according to a predetermined program, no manual intervention is required during the machining process, and the machining accuracy can also be corrected and compensated by the software, so that the machining accuracy of the parts can be improved and the quality of the products can be stabilized. This is especially true for parts with many varieties and fewer batches.

The application of numerical control technology has caused a qualitative change in the traditional manufacturing industry, especially in recent years. The development of microelectronics and computer technology has brought new vitality to CNC technology. CNC technology and numerical control equipment are important foundations for industrial modernization in various countries. CNC machine tools are the mainstream equipment of modern manufacturing industry. The necessary equipment for precision machining is an important symbol reflecting the level of modern machine tools and the level of modern machinery manufacturing. It is a strategic material that relates to the national economy and the people's livelihood and the cutting-edge construction of national defense. Therefore, all industrialized countries in the world have taken major measures to develop their own numerical control technology and its industry. CNC machining CNC is the abbreviation of English Computer Numberical Control, which means "computer data control", which is simply "CNC machining". In the Pearl River Delta region, people call it "computer ". CNC machining is an advanced machining technology in today's machinery manufacturing, and it is an automated processing method with high efficiency, high precision and high flexibility. It is a CNC program that processes the workpiece to the machine tool. Under the control of these data, the machine automatically processes the workpiece according to people's wishes to create a wonderful product.

Tel: http://alu-forging.com Reference: Bicycle Aluminum Forging The processing technology of CNC machine tools has many similarities with the processing technology of ordinary machine tools, and the principles followed are basically the same. There are also many differences. The biggest difference is in the control of the cutting tool path. At the same time, because of the high degree of automation of CNC machine tools and the high cost of equipment, CNC machine tools have formed their own characteristics: 1. The process design of CNC machining is very specific. When using general-purpose machine tools, many specific process problems, such as the division and arrangement of steps in the process, the geometry of the tool, the path of the cutting tool and the amount of cutting, etc., to a large extent They are all considered and decided by the operating workers based on their own practical experience and habits. Generally, there is no need for the craftsman to make excessive regulations when designing the process rules. In the processing of numerically-controlled machine tools, the above-mentioned specific technological problems not only become the contents that must be considered when designing the numerical control process, but also must make correct choices and be incorporated into the processing program. 2. CNC machining process design is very strict Although C

In the processing of precision hardware, there are fine, efficient, and long-lasting molds. Without high-precision presses and high-quality precision hardware materials, precise and efficient stamping cannot be achieved; the precision and rigidity of the precision hardware processing equipment press It has a great influence on the life of the mold, and also has a great influence on the precision hardware. 1. The accuracy of a press is usually expressed by its static and rigidity. The static accuracy can be divided into special grade, level 1, level 2, and level 3. The rigidity of the press is also an important element, which is the strength of the press; 2. The precision hardware processing equipment press must be deformed while receiving the load. The capacity of the press must be determined according to the amount of deformation. The fine blanking process must be performed under 50% of the machining capacity of the press, if it exceeds its capacity. At 80%, the uniformity of the mold gap cannot be guaranteed, the high-precision press can extend the life of the mold, and the quality of the precision hardware produced is good; 3. In the zigzag forming process, the static accuracy of the precision hardware processing equipment press has little effect on the part, but the rigidity of the press has a certain influence on the part; 4. The rigidity of the press has a greater impact on the quality of the parts, but the rigidity is low, and it can be compensated by the method that the processing pressure is lower than the nominal pressure. However, the accuracy of the press is not high, which has a direct impact on the life of the mold. High-speed active presses for high-precision parts, special punching presses, cold extrusion presses, embossing toggle presses, hot forging presses, etc. should all be designed with high rigidity.
