High -power LED Lamp Beads (imitation Flow) Knowledge Daquan, Quickly Collect It

Compared with small -power LED lamp beads, high -power LED lamp beads, higher power, brighter brightness, and higher price. The rated current of small power LED lamp beads is often 20mA, and the rated current can basically be counted as high power. Common power files are: 0.25W, 0.5W, 1W, 3W, 5W, 8W, 10W, etc. The brightness unit is LM (lumen), and the brightness unit of small power is generally MCD (millaka, 1cd = 1000mcd), which is also the Lighting intensity I. The high -power lamp beads are mainly imitation bright lamp beads, as shown in the figure below. During the application process of high -power LED products and devices, heat dissipation, electrostatic protection, and welding have a great impact on their characteristics. Zhuhai manufacturers specialize in the production of high -power LED lamp beads, small -power LED lamp beads, manufacturers mass production, affordable price! 1. Due to the limitations of semiconductor light -emitting diode chip technology, the conversion efficiency of LED needs to be improved, especially high -power LEDs. Due to its high power, a large part of the electric energy can be transformed into heat energy release (with the development of semiconductor technology, conversion conversion Efficiency is gradually increasing), which requires end customers to do a good job of heat dissipation when applying high -power LED products to ensure that the normal work of high -power LED products work. 1. The heat sink requires that if the finished sealing requirement is not high, it can directly flow with the external air environment. The manufacturer recommends that the aluminum or copper heat sink with fins with fins can be used. 2. Effective heat dissipation surface area for 1W high -power LED white light (other colors are basically the same), and manufacturers recommend the sum of the effective heat dissipation surface area of the heat dissipation tablet≥50-60 square meters; for 3W products, it is recommended to take valid heat dissipation surface area for 3W products≥150 square meters; higher power depending on the situation and test results, try to ensure that the temperature of the heat sink does not exceed 60 C. 3. When the connection method is connected to the high -power LED substrate to ensure that its contact surface is flat and good contact. In order to strengthen the degree of combination of the two contact surfaces, the manufacturer recommends that the thermal silicon grease is applied at the bottom of the LED substrate or the surface of the heat sink (heating silicone grease grease in thermal conductivity. Thermal Conductivity≥3.0W/m.k), thermal silicon grease requires a uniform and appropriate amount, and then fix it with screws. Second, electrostatic protection LED is a semiconductor device, which is more sensitive to static electricity, especially for white, green, blue, and purple LEDs. 1. The generation of static electricity friction: In daily life, after the contact of any two different materials of objects is separated, it can generate static electricity. The most common way to generate static electricity is to friction of raw electricity. The better the insulation of the material, the easier it is to rub the electricity. In addition, if any two different types of objects are separated after contact, it can also generate static electricity. Induction: For conductive materials, because electrons can flow freely on its surface, if it is placed in a electric field, due to the same sex, the opposite sex is sucking, positive and negative ions will be transferred, and the charge will generate charge on its surface. Transmission: For conductive materials, because electrons can flow freely on its surface, such as contact with the electrical body, charge will be transferred. 2. The harm of static electricity to LED Due to the heat generated by the instantaneous electric field or current, the LED local injuries are injured. Due to the insulation layer of the electric field or current destroying the LED, the device cannot work (completely damaged), which is manifested as a dead lamp. 3静电防护及消除措施对于整个工序生产测试包装等所有与LED直接接触的员工都要做好防止和消除静电措施厂家分析6点主要有1车间铺设防静电地板并Do a good job. 2. The workbench is the anti -static workbench, the production machine is well grounded. 3. Operators wear anti -static uniforms, with anti -static bracelets, gloves or footsteps. 4. Apply ionic fan. 5. Welded electric iron for grounding measures. 6. Packaging uses anti -static materials. 3. Welding points 1. Select the constant temperature soldering iron when welding. The welding temperature is below 260 C. 2. If the high -power LED encapsulated by silicone, the maximum heat resistance temperature of silicone is 180 C. Therefore, the welding temperature of LED must not exceed 170 C. The time does not exceed 3S. Fourth, advantages analysis 1. Less power consumption: LED with a light -emitting effect of 75LM/W is greatly reduced than incandescent lights with the same brightness. 2. Long life: the product life is as long as 50,000 hours, and it can be lit for 5 years in 24 hours. 3. The nano -second -level response speed makes the dynamic control of brightness and color simple: it can achieve color dynamic changes and digital control 4. Large design space: can achieve the integration with the building to achieve the effect of seeing the light and the lights and lights. 5. Environmental protection: no harmful metal mercury, non -infrared and ultraviolet radiation. 6. Color: Different wavelengths generate different color light, bright saturation, no filtering filter, can be controlled with three primary colors of red, green and blue, to form a variety of different colors, which can achieve a variety of color deformation effects such as full color gradient.
