Analysis of the advantages of high-power LED lighting

High-power LED lighting fixtures are one of the most important means to improve luminous flux. It has many advantages, but it also has disadvantages. How to use high-power LED lighting fixtures is the key. Compared with other light sources, high-power LED lighting fixtures, LED lighting The fact that the luminaire is called a green light source is well deserved. Research on high-power LED lighting fixtures leads to the following conclusions:

Advantages of high power LED lighting:

1. Dynamic control of brightness and color is easier: continuous brightness adjustment, high color purity, color dynamic conversion and digital control;

2, long life: LED product life can be as long as 55,000 hours, 24 hours continuous lighting available for 6 years;

3. Low power consumption: LED lamps with a luminous efficacy of 60 lm/W will reduce power consumption by about 80% compared with incandescent lamps of the same brightness;

4, environmental protection: no harmful metal mercury, no infrared and ultraviolet radiation;

5, flexible size: can achieve organic integration with the building, to achieve the effect of seeing only the light;

LED high-power lighting fixtures that combine so many advantages make us feel that it is a valuable job to promote it, but it also has some shortcomings, such as low color rendering in white lighting. At present, the white LED produced by yellow phosphor and blue light has a color rendering index of about 80, which is ok as general illumination, but it is insufficient for some places with high color resolution requirements, although by adding appropriate red phosphors and the like. It is possible to increase the color rendering index to 90 or higher, but there is still a certain gap compared with the 99 of incandescent lamps, and its efficiency will be affected. Therefore, in terms of color rendering, high-power LED lighting fixtures need to be fixed. The improvement, the last point, as for the problem of excessive price, in fact, considering the comprehensive cost, the use of LED lighting in many occasions still saves a lot of cost.
