LED light source features

1 New green environmental protection light source: LED uses cold light source, glare is small, no radiation, no harmful substances are produced during use. LED operating voltage is low, using DC drive mode, ultra-low power consumption (single tube 0.03 ~ 0.06W), electro-optical power conversion is close to 100%, energy saving more than 80% than traditional light source under the same lighting effect. LEDs have better environmental benefits, no ultraviolet and infrared rays in the spectrum, and waste can be recycled, no pollution, no mercury, and can be safely touched. It is a typical green lighting source.

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

3 multi-transformation: LED light source can use the three primary colors of red, green and blue. Under the control of computer technology, the three colors have 256 gray levels and can be mixed arbitrarily, which can produce 256X256X256 (ie 16777216) colors, forming different light colors. The combination. The color of the LED combination is varied, enabling a variety of dynamic changes and various images.

4 High-tech: Compared with the light-emitting effect of traditional light sources, LED light source is a low-voltage microelectronic product, which successfully combines computer technology, network communication technology, image processing technology and embedded control technology. The chip size used in the conventional LED lamp is 0.25 mm×0.25 nm, and the size of the LED for illumination is generally 1.0 mm×1.0 mm or more. LED die-formed work-table structures, inverted pyramid structures, and flip-chip designs improve their luminous efficiency and deliver more light. Innovations in LED package design include high-conductivity metal block substrates, flip-chip designs, and bare-plate cast leadframes. These methods can be used to design high-power, low-thermal resistance devices, and these devices have higher illumination than conventional LEDs. The illuminance of the product is greater.

A typical high-throughput LED device can generate lumens of several lumens to tens of lumens. The newer design can integrate more LEDs in a single device or install multiple devices in a single assembly, resulting in lumens output. Equivalent to a small incandescent lamp. For example, a high-power 12-chip monochrome LED device can output 200 lm of light energy, which consumes between 10 and 15 W.

The application of LED light source is very flexible, and it can be made into light, short and short products of various forms such as point, line and surface. The control of LED is very convenient. As long as the current is adjusted, it can be dimmed at will; the combination of different light colors is multi-end, using timing control. The circuit can achieve a variety of dynamic changes. LEDs have been widely used in a variety of lighting equipment, such as battery-powered flashlights, miniature voice-activated lights, safety lights, outdoor road and indoor stair lights, and buildings and marked continuous lights.

The emergence of white LEDs is a substantial step in the LED's transition from the identification function to the illumination function. White LEDs are closest to daylight and 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. At present, white LED has begun to enter some application fields, such as emergency lights, flashlights, flashlights and other products, but because of the high price, it is difficult to popularize. The premise of the popularity of white LEDs is that prices are falling, and the price decline must be made after the white LEDs form a certain market size. The integration of the two depends on technological progress.
