Do you know what an LED light is? I believe that many friends are not very clear about this concept, but they should have been exposed to LED lights. At present, LED lighting can be seen everywhere in our lives, especially at night, a variety of LED lights can be found in every corner of every city, bringing a very beautiful light show to the city, so do we know the characteristics of LED lights? ? Let's take a look:

LED lamp beads are a kind of light-emitting diodes, which can convert electrical energy into light energy. It changes the luminous principle of the tungsten filament of the incandescent lamp and the luminous principle of the three-color powder of the energy-saving lamp, and uses electroluminescence. LED lights can use DC 220V voltage without starter and ballast. Short start-up time, no flicker. The main features of LED lights are:

①New green environmental protection light source: LED uses cold light source, with low glare, no radiation, and no harmful substances during use. The working voltage of LED is low, it adopts DC drive mode, power consumption is very low (single tube 0.03~0.06W), electro-optical power conversion is close to 100%, which is more than 80% energy-saving than traditional light sources under the same lighting effect. LED has better environmental benefits. There is no ultraviolet and infrared in the spectrum, and the waste is recyclable, non-polluting, mercury-free and can be touched safely. It is a typical green lighting source.

②Long life: LED is a solid cold light source, epoxy resin encapsulation, anti-vibration, there is no loose part in the lamp body, there are no shortcomings such as easy burning of the filament, heat deposition, light decay, etc., and the service life can reach 60,000 to 100,000 Hours, more than 10 times the service life of traditional light sources. The LED performance is stable and can work normally under the environment of -30~+50oC.

③Multi-conversion: LED light source can use the principle of red, green and blue three primary colors, under the control of computer technology, make the three colors have 256 gray levels and mix them arbitrarily, which can produce 256X256X256 (that is, 16777216) colors to form different light colors combination. There are many changes in the light color of the LED combination, which can realize colorful dynamic changes and various images.

④High and new technology: Compared with the luminous effect of traditional light sources, LED light sources are low-voltage microelectronic products, which successfully integrate computer technology, network communication technology, image processing technology and embedded control technology. The chip size used by the traditional LED lamp is 0.25mmX0.25nm, and the size of the lighting LED is usually above 1.0mmX1.0mm. The worktable structure, inverted pyramid structure and flip chip design of LED mold molding can improve its luminous efficiency, thereby emitting more light. Innovations in LED packaging design include high-conductivity metal block substrates, flip-chip designs and bare-disk casting lead frames. These methods can be used to design high-power, low-thermal resistance devices, which have better illuminance than traditional LEDs. The illuminance of the product is greater.
