The Analysis Of The Advantages And Disadvantages Of High Power Multi Color LED

High power LED is one of the most important means of achieving high luminous flux. There are many advantages and disadvantages to using high power multi color led lighting. How to use high power multi color led is the key. At the same time, this essay compares high power multi color led lighting products with traditional lighting products, and also discusses the application of high-light LED in lighting field. There are many advantages and disadvantages to using high power multi color led lighting. How to use high power multi color led is the key. At the same time, this essay compares high power multi color led lighting products with traditional lighting products, and also discusses the application of high-light LED in lighting field.

Ordinary high-brightness white light LED have reached 100 lm/W in the laboratory, and 50 lm/W high power white LED have also entered commercialization. In terms of color light, the light effects of red light, yellow light, blue light and green light are also constantly being recorded. As a new light source, the application range of LED is becoming wider and wider, and it has gradually attracted more people's attention and expectation.

The characteristics of high power multi color led, compared with other light sources in the lighting industry, compared with traditional light sources, it shows an irreplaceable advantage in some aspects: high power multi color led as a light source for lighting has the following advantages:

1, Low power consumption: LED with a luminous efficacy of 75 lm/W are reduced by about 80% compared with incandescent lamps of the same brightness;

2, long life: the life of the product is up to 50,000 hours, 24 hours of continuous lighting available for 7 years;

3, the dynamic control of brightness and color is easy: the brightness can be continuously adjusted, the color purity is high, and the color dynamic conversion and digital control can be realized;

4, flexible size: it can achieve harmonious integration with the building, to achieve the effect of seeing only the light;

5, environmentally friendly: no harmful metal mercury, no infrared and ultraviolet radiation;

6, color: bright saturated, pure, no filter, variable, mixed light effect, excellent color rendering. With so many advantages in one, we feel that it is a valuable job to promote the use of LED.

However, LED also have insufficient aspects compared with other light sources, such as low color rendering in white light illumination. High power white LED currently produced with yellow phosphors and blue light have a color rendering index of about 80. It is enough as general lighting, but it is insufficient for some places where color resolution is high. Although the color rendering index can be increased to 90 or higher by adding a suitable red phosphor, etc., there is still a certain gap compared with the 99 of the incandescent lamp, and its efficiency is affected.
