A typical high-flux LED device can produce a few lumens to tens of lumens of luminous flux, and newer designs can integrate more LEDs in a single device, or multiple devices in a single assembly, resulting in comparable lumens output for small incandescent lamps. For example, a high-power 12-chip monochrome LED device can output 200lm of light energy and consumes between 10 and 15W of power.

The application of LED light source is very flexible, and it can be made into light, thin and short products in various forms of point, line and surface; LED is extremely controlled, as long as the current is adjusted, the light can be adjusted at will; the combination of different light colors is varied, and the sequence control circuit is used. , which can achieve a variety of dynamic changes. LEDs have been used in a wide variety of lighting applications such as battery-operated flashing lights, tiny voice-activated lights, security lights, outdoor road and indoor stair lighting, and building and signage continuous lighting.

The emergence of white LEDs is a substantial step for LEDs from the identification function to the lighting function. White LED is the closest to sunlight and can better reflect the true color of the illuminated object, so from a technical point of view, white LED is undoubtedly the most cutting-edge technology of LED. White LEDs have begun to enter some application fields, and emergency lights, flashlights, flashlights and other products have come out one after another, but they are difficult to popularize due to their high prices. The premise of the popularization of white LED is the price drop, and the price drop can only be possible after the white LED has formed a certain market scale. The integration of the two ultimately depends on technological progress.
