What factors mainly depend on the heat dissipation of high-power LED street lights?

 The heat dissipation of high-power LED street lights still depends on several aspects:
1. The heat sink design of the lamp body;
2, the heat-conducting material and chip of the lamp bead bracket;
3. The assembly process. These are the reasons that affect the heat dissipation.

This question is very good. You are also a major problem in the high-power LED lighting industry. Especially the heat dissipation of high-power LED street lighting has always been a problem. The heat dissipation of high-power LED lamps cannot be simply said. Is it the lamp bead problem or the lamp design problem, this problem must be divided into two aspects:

1, the high-power LED lamp beads themselves, you can choose lamp beads with high production technology, good technical content, and low light decay to make street lights.
2: The design of the lamp itself is also very important, and these technologies have yet to be developed by professional technicians.
Heat dissipation is actually a systemic problem. The easiest way is to add a heat sink to the lamp body; 3528 Smd Led Diode is your good choice.
A major technical problem of LED street lamp products, the chip of the LED lamp beads and the structure of the lamp body, these aspects directly affect the stability and quality of the LED lamp products. Poor heat dissipation is reflected in the increase of the light attenuation of the lamp beads. , The time is advanced, on the one hand, it is reflected in the shortened life of the internal components of the LED power supply, which causes the driving power supply to be easily damaged. At present, there are quite a few domestic manufacturers of lamp beads, lamp manufacturers, and driving power supply manufacturers, but it depends on the designer's product design to better solve these two or three problems and determine the quality and life of the product.
In the current high-power LED lamp beads, the chips are generally imported from abroad with good quality. Our domestic high-power LED lamp beads manufacturers usually further process the chips according to different brand manufacturers. Of course, LED The production technology of the chip needs to be improved in terms of cost and heat dissipation in order to be more conducive to the further development of the LED industry. However, the LED lamp bead production plant currently does not have much ability and help to solve the above chip problems. Therefore, under the condition that the existing chips have not changed much, the policy of making up for the innate shortcomings is that the lamp manufacturers should fully consider the heat dissipation of the lamp beads when designing the lamps. This will cause the lamps produced by different manufacturers. The structure has different lifespans and different qualities. In addition, all manufacturers are working together on low-cost and low-cost lighting solutions, which has caused the current LED lighting products in the market to worry about the situation. .
On the other hand, LED driving power is also one of the main factors that directly and fatally affect the life of the entire LED lamp. At present, most of the products on the LED power supply market pursue a low-cost, low-quality situation, as long as the lamp can be lit, it can be Design the power supply with the mentality of getting customers, and the mentality of being able to grab an order at a lower price. The psychology of this part of the people is that they don’t think of any plan to improve product efficiency, to achieve a product with a high power factor PF>95 or higher, and the effective power of the product to achieve the goal of 90% or higher. Power supply, not to mention that not many people are dedicated to the quality of the product. Whether the product can guarantee the durability of the whole lamp for 50,000 hours or more than 100,000 hours has a higher demand for development. The current LED lighting products have a light decay life of less than 0.3-0.5% after 20,000 hours. There are really not many products, let alone ensure that the luminous decay is smaller within 50,000 hours and 100,000 hours. Products too. People all over the world develop LED lights to be more environmentally friendly, save energy, and reduce heat emissions. We hope that everyone has a big goal of contributing to society and benefiting the earth and mankind. R & D do some high requirements and high quality. , More environmentally friendly and energy-saving products. We produce quality 3528 Smd Led Diode.
