When purchasing LED lighting fixtures, we often see the propaganda statements of businesses that are, XX watt high-power LED wall washer, XX watt low-power LED wall washer, waterproof high-power LED wall washer, and so on. So the question is, what is a high-power LED? LED lighting manufacturers led factory lighting to answer for you.
In the LED lighting industry, high-power LED broadly refers to a single LED light source power greater than 0.35W (including 0.35W).
There are two ways to apply LED light sources to lighting fixtures, one is to use traditional low-power LEDs as a combination, generally up to hundreds or even hundreds, and the power supply design is complicated. The other is to use a high-power tube as a light source, which is more expensive. Both methods inevitably take heat dissipation design and working reliability as the main design considerations. Domestically, they are mostly used in government demonstration projects, and there are few projects that are truly market-oriented. There are many examples of applications in this area abroad, but they The biggest shortcomings are still reliability, luminous lumens and price. Many projects do not show the advantages of long life due to the poor quality of LEDs. In addition, from the perspective of cost and market, whether LED is used as a lighting source in combination with solar energy requires a different route in design, and it cannot be developed as a light source alone.
Although many companies in China develop and produce LED urban lighting street lights, many of them use low-power LED arrays as luminous bodies, and the heat dissipation problem is solved. The number of LEDs used is large, and low-power LEDs have strong light decay and high installation costs; The use of high-power LEDs in urban lighting LED street lights is a development trend. The few street lamp products that use high-power LEDs as luminous bodies do not solve the heat dissipation problem of LEDs when the power reaches a certain amount; LED astigmatism and concentration control problems; The problem of the illumination range, type and illuminance balance of the street lamp on the illuminated surface of the road; the photoelectric conversion efficiency is too low, only a few lumens per watt, etc. Therefore, the product performance is still not satisfactory; the price of high-performance products remains high and it is difficult to popularize. Heat dissipation and reliability are the main factors affecting LED applications.
Generally speaking, whether it is high-power LED or low-power LED, it has its characteristics and advantages. Only when it is applied to the right place, the value of LED can be fully utilized.
