LED light source

① New type of 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, ultra-low power consumption (single tube 0.03~0.06W), electro-optical power conversion is close to 100%, and it can save more than 80% energy 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 can be recycled, no pollution, no mercury, and safe to touch. It is a typical green lighting source.

② Long life: LED is a solid cold light source, epoxy resin encapsulated, anti-vibration, there is no loose part in the lamp body, there are no shortcomings such as easy burning of filament, heat deposition, light decay, etc., and the service life can reach 60,000~100,000 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~+50°C.

③ Multi-conversion: LED light source can use the principle of red, green and blue three primary colors. Under the control of computer technology, the three colors can have 256 gray levels and mixed arbitrarily to produce 256X256X256 (that is, 16777216) colors to form different light colors. The combination. The light color of the LED combination changes many ends, which can realize colorful dynamic change effects and various images.

④ High 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 in the traditional LED lamp is 0.25mmX0.25nm, and the size of the lighting LED is generally above 1.0mmX1.0mm. The working bench structure, inverted pyramid structure and flip-chip design of LED die 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, and these devices have better illuminance than traditional LEDs. The illuminance of the product is greater.

A typical high luminous flux LED device can produce a luminous flux of several lumens to tens of lumens. The newer design can integrate more LEDs in one device, or install multiple devices in a single assembly, so that the output lumens is equivalent For small incandescent lamps. For example, a high-power 12-chip monochromatic LED device can output 200lm of light energy, and the power consumed is between 10-15W.

The application of LED light source is very flexible, and it can be made into light, thin and short products in various forms of dots, lines, and surfaces; LEDs are extremely controllable, as long as the current is adjusted, they can be dimmed at will; the combination of different light colors can vary widely, using sequential control circuits , It can achieve a variety of dynamic changes. LEDs have been widely used in various lighting equipment, such as battery-powered flashlights, miniature voice-activated lights, safety lighting, outdoor road and indoor staircase lighting, and continuous lighting for buildings and signs.

The emergence of white LEDs is a substantial step for LEDs from marking functions to lighting functions. White LED is the closest to daylight and can better reflect the true color of the illuminated object. So from a technical point of view, white LED is undoubtedly the most advanced technology of LED. White light LEDs have begun to enter some application fields, and products such as emergency lights, flashlights, and flashlights have come out one after another, but because they are very expensive, they are difficult to popularize. The prerequisite for the popularization of white LEDs is the price drop, and the price drop can only be possible after the white LED has formed a certain market size. The integration of the two ultimately depends on technological progress.
