It is no stranger to losing LED lamps, but it may not know much about LED high -power lamp products. During the application process of LED high -power lamp products and devices, heat dissipation, electrostatic protection, and welding have a great impact on their characteristics. It needs to cause cause Pay attention to the application of customers. Let me briefly introduce you how to reduce temperature rise and how to avoid corrosion corrosion in high -power LED lamp beads. 1. How to reduce the temperature of high -power LED lamp beads. At present, the heat dissipation methods of LED lights mainly include natural convection and heat dissipation, installed fans forced heat dissipation, heat pipe and circuit heat pipe heat dissipation, etc. 1. The separation of the power supply from the light body is separated from the power supply itself, which increases the heat source of the LED lamp. At the same time, the integration of the power supply and the lights makes the LED lights unevenly heated as a whole. These factors will cause fatigue and early failure of the lamp, which will affect its life span. 2. The choice of selection of high -quality LED module LED modules also plays a critical role in lowering temperature rising. Choose LED lamp beads encapsulated by the high heat conduction coefficient and consistent material, which can improve the internal heat diffusion. The metal substrate with high heat -conducting and high heat dissipation is used as a light core plate to make the temperature distribution evenly, so that the heat dissipation effect is maximized. 3. Increasing the heat dissipation area aluminum substrate and the interface of the heat dissipation tablet is easy to have gaps, and the heat conduction coefficient of the air is very small, only about 0.03W/m·K, so it can be applied to the contact surface with higher thermal conductivity on the contact surface to increase the actual contact area. At the same time, increase the heat dissipation area of the heat sink and deform the structure of the heat sink to facilitate heat dissipation. Second, how to avoid corrosion of high -power LED lamp beads: high -power LED lamp beads can continue to operate under most different conditions. However, once the LED lamp beads are corroded and the LED lamp beads are chemically reacting by the surrounding environment, the performance of LED lamp beads will be reduced. Avoiding the corrosion of LED lamp beads is an important part of improving the reliability of LED lamp beads. The reliability of LED lamp beads is one of the important specifications used to estimate the life of LED lamp beads. Tianhui photoelectric analysis of the reasons why LED lamp beads are corroded and given how to avoid the corrosion of LED lamp beads.——Avoid LED lamp beads close to harmful substances, and effectively limit the concentration level and ambient temperature of harmful substances. In order to avoid the corrosion of LED lamp beads, avoid contact with the O -shaped circles (O -RING), padding, organic rubber, foam pads, seal rubber, sulfur -containing elastic body, shockproof pads and other harmful substances. Even a small amount of harmful substances can cause LED lamp beads to corrode. Even if LED lamp beads only contact with corrosive gas during the processing process, such as machines in the production line may have adverse effects. In these cases, you can usually observe whether the LED lamp bead component is damaged before the actual system settings. If LED lamp beads cannot completely avoid these harmful substances, LED lamp beads with higher corrosion resistance should be used. The above is about“How does high -power LED lamp beads reduce temperature rise and avoid anti -corrosion?”For a brief introduction, please pay attention to this site if you need it.

For quality issues, friends often ask friends how to distinguish, how to buy, how to buy. Whether there are guarantees such as quality, Tianhui Optoelectronics has produced light -emitting diodes for 20 years, and quality is guaranteed in quality. 1. The quality of the lamp beads: the quality of the lamp bead determines the quality of the chip. The quality of LED lamp beads light-emitting chips determines that the brightness of LED lamp beads is not high, and those chips are inferior products with 1-2 cents. After a period of use The characteristics of the product are high brightness and stable performance. 2. Color temperature: The color temperature grading is as small as possible, so that when a large number of LEDs are lit together, it will not be too yellow because of the color temperature difference, which is a bit yellow. 3. Heating: If the heat dissipation conditions are not good, the lamp beads work at high temperature for a long time, the light decay will be very large, and the service life will be reduced. 4. Salaring: The brightness of the lamp beads is divided, and there is a luminous distribution or the intensity of the light. It is recommended to purchase LEDs, or based on light efficiency, highlighting products can save energy and long life. 5. Glossoms: The fluorescent powder should be stirred with glue and then on the chip. The quality of the glue affects light decay and color drift. The poor glue time will be yellow, and the light decay will increase. Good glue is jelly. glue. 6. fluorescent powder: white light beads are made of blue -light chip and yellow fluorescent powder. The fluorescent powder is mainly divided into aluminum acid and silicate. The performance of aluminate is better than silicate. Aluminum acid is YAG. YAG has stable performance, low light decay, and poor chemical stability of silicate itself, but the brightness is higher than YAG. Don't be fooled by the so -called high brightness, this is a big problem. The editor explains that the lamp beads are good or bad. If you need to buy more products, you can directly contact the online customer service consultation.

Applicable range of UV sterilization lamp tube: UV sterilization lamp tube commonly known as: light wave disinfection lamp, sterilization lamp, UVC sterilization lamp tube, ultraviolet disinfection lamp tube. UV sterilization lamps are widely used in hospitals, food industry, pharmaceuticals, schools, kindergartens, cinemas, buses, offices, families, etc. Purifying the air, eliminating the smell of mold, and a certain amount of negative oxygen ions can be produced. In public, disinfection by ultraviolet rays can avoid some germs from spreading through air or the surface of the meridian. UV sterilization lamps also have significant application significance in water disinfection and environmental protection engineering. What are the advantages of the white LED lamp beads obtained by the purple LED lamp beads? 1. High color rendering index. This white LED lamp bead is obtained by the fluorescent body through purple LED lamp beads to obtain blue light. The peak strength of the blue light is not high. Moreover, it can also output all light within the range of light wavelengths, so the color rendering index is relatively high, which can realize ideal white like sunlight. And its red color rendering index "R9" is particularly high, and the average color rendering index "RA" is also as high as 95. 2. Elapnge. (1) The purple LED lamp chip chip is triangular, and the shape of the ordinary LED lamp bead chip is quadrilateral. Compared with it, the light emitted by the luminous layer of the triangular LED lamp chip to the efficiency (light extraction efficiency) is higher. Because the crystal quality and light extraction efficiency of the purple LED lamp beads are high, the light output except the "WPE (Wall-Plug Efficience)" obtained by the input of electricity, it can reach 84%. The WPE of ordinary blue light -emitting diode is only 50-60%. (2) Because the purple LED lamp bead is made of GAN substrate, it is made of purple LED lamp chips on the GAN substrate. It is relatively high, so the purple LED lamp beads shine, and the efficiency is improved quickly. Heat management, the key to improving the life of UVCLED: 1. The same materials and craftsmanship, the heat management effect may still be different. 1. Do a good job of heat management. The key is to reduce the welding hollow rate in the welding process. The defects formed by the welding empty hole refers to the formation of the LED chip and the substrate welding process. The state of the empty shape is an important indicator that affects the heat dissipation. The lower the welding empty rate of the welding, the better the heat dissipation effect, and the longer the product life. , UVC LED wholesale, the better the quality. 2. The heat dissipation of the light source module is also one of the key. For the multi -chip integrated UVC LED, the more integrated chips, the more severe the heat dissipation problem. Although the manufacturer will improve the heat dissipation effect by reducing the welding empty hole, the aluminum substrate is not the end of the radiator. After the heat generated by the LED lamp beads is transmitted to the aluminum plate, the aluminum substrate needs to be transmitted to the heat sink through the heat -conducting interface material to the heat dissipation on the radiator. The heating interface material can provide an effective thermal conductivity for the gaps and rough surface texture between the aluminum substrate and the heat dissipation tablet. UVC LED manufacturers will improve the heat dissipation efficiency of the module. The variety of thermal interface materials, high compression, super soft, can be used as a thermal silicon film that can be used as a vibration absorption body, can also be applied to UV LED. With the further expansion of the UVC LED market, manufacturers need to consider new methods to cope with this challenge. At present, the problem is still how to deal with the high fever demand of UV LED, while ensuring that the component maintains cost -effectiveness, durability, and resistance to UV light sources itself. The UVC disinfection technology implemented by LED can bring real change effects. In industrial development, it is necessary to ensure that it can overcome the heat challenge faced by UV LED.
