The application of LED light source is very flexible, and it can be made into light, thin and short products in various forms such as dots, lines, and surfaces. The control of LED is extremely easy, as long as the current is adjusted, the light can be adjusted at will. , Can achieve a variety of dynamic changes. LEDs have been widely used in a variety of lighting equipment, such as battery-powered flashes, miniature voice-activated lights, safety lights, outdoor road and indoor staircase lights, and continuous lighting for buildings and signs.
The emergence of white LEDs is a substantial step for LEDs from the identification function to the lighting function. White LED is closest to daylight and can better reflect the true color of the illuminated object. Therefore, from a technical point of view, white LED is undoubtedly the most cutting-edge technology of LED. White light LEDs have begun to enter some application areas. Products such as emergency lights, flashlights, flashlights have come out one after another, but because the prices are very expensive, it is difficult to popularize them. The premise of the popularization of white LEDs is price reduction, and price reduction is only possible after white LEDs have formed a certain market size. The integration of the two depends on technological progress.
The biggest advantage of LED lights is energy saving and environmental protection. The luminous efficiency of light reaches more than 100 lumens / watt, ordinary incandescent lamps can only reach 40 lumens / watt, and energy-saving lamps hover around 70 lumens / watt. Therefore, for the same wattage, the effect of LED lights will be much brighter than incandescent and energy-saving lamps. The brightness of a 1-watt LED lamp is equivalent to an energy-saving lamp of about 2 watts. A 5-watt LED lamp consumes 5 degrees of power for 1000 hours. The life of the LED lamp can reach 50,000 hours.
