The LED light source

- Aug 23, 2016 -

(1) a new type of green environmental protection light source: LED cold light source use, small glare, no radiation, does not produce harmful substances in use. LED low working voltage, the use of dc drive mode, ultra-low power consumption (0.03 ~ 0.06 W single pipe), electric power conversion is close to 100%, under the same lighting effect than the traditional light source, energy saving more than 80%. LED the environmental benefits of better, no ultraviolet and infrared spectrum, and waste recycling, no pollution, no mercury elements, can safely touch, belongs to typical green lighting source.

(2) long life: LED solid cold light source, epoxy resin encapsulation, shock resistant, no loose parts in the body, there is no filament light easy to burn and thermal deposition, droop, such as faults, service life can reach 60000 ~ 100000 hours, is a more than 10 times the service life of the traditional light source. LED performance is stable, can be in - 30 ~ 50 ° C + normal work environment.

(3) transform, the LED light source available red, green, blue three colors principle, in under the control of computer technology make the three colors gray level 256 and arbitrary mixed, can produce 256 x256x256 (16777216) colors, forming different color combinations. Combination of LED light color changing, can realize the dynamic change of rich and colorful effects and all kinds of images.

(4) : high and new technology compared with traditional glow of light, LED light source is low pressure microelectronics products, successfully combines computer technology, network communication technology, image processing technology and the embedded control technology, etc. Traditional LED lights used in the chip size is 0.25 mmX0.25 nm, and the size of the LED lighting is typically mmX1.0 in 1.0 mm and above. LED bare chip forming work table structure, the inverted pyramid structure and flip chip design can improve the luminous efficiency, thus more light. LED packaging innovation including the design of high conductivity metal base, flip chip design and bare plate casting type lead frame and so on, these methods can design a high power, low thermal resistance of the device, and the device of the illumination intensity of illumination is greater than traditional LED products.

A typical high flux LED device can produce several lumens to dozens of lumen flux, update the design can be integrated in a device more leds, or multiple devices can be installed in a single assembly, so that the number of lumen output is equal to the small bulb. For example, a high power 12 monochromatic LED chip light energy device can output 200 lm, the consumed power between 10 ~ 15 w.

The application of LED light source is very flexible, used as the dot, line, face various forms of lightweight products; LED control extremely, as long as adjust current, it can adjust light; A combination of different light color changing, the sequential control circuit, can achieve more dynamic change of rich and colorful effect. LED has been widely applied in all kinds of lighting equipment, such as a battery-powered flashlight, mini voice control lamp, security lighting, outdoor and indoor stair floodlight roads and buildings and tag continuous lighting.

The emergence of white LED is LED from the identification to the illumination function across a substantive step. White LED closest to the sun, more can well reflect the reality of the irradiation object color, so from a technical perspective, white LED is undoubtedly the most cutting-edge LED technology. White LED has began to enter some application field, emergency lights, flashlights, flash and other products appeared, but because the price is very expensive, so hard to popularize. White LED popularization is the premise of price decline, and prices must be formed in the white leds is possible after a certain market scale, integration of the two end depends on technology progress.
