LED light source characteristics

Editor this paragraph of LED light source characteristics
The new green light: the use of LED cold light, glare, no radiation, use does not produce harmful substances. LED low working voltage, DC drive, ultra low power ( single0.03 ~ 0.06W ), LED Lighting module electric power conversion is close to 100%, in the same lighting effect than the traditional energy-saving light source above 80%. LED environmental protection benefit are better, no ultraviolet and infrared spectrum, and recyclable waste, no pollution, no mercury element, safe touch, typical of green lighting source.
The long life: LED as solid cold light source, epoxy resin package, shock resistance, light body and no loose parts, there is no filament lights burning, heat deposition, attenuation etc, the service life of up to60000~ 100000 hours, is the traditional source lifetime of more than 10 times. LED stable performance, can be in -30 ~ +50oC environment to normal operation.

The multiple transformation: LED light source can use red, green, blue three primary colors principle, in computer technology under the control of the three colors with256 gray levels and arbitrary mixed, can generate256X256X256( i.e. 16777216) colors, forming different color combinations. LED combination of light be the most changeful, can realize the rich and colorful dynamic effect and various image.

The new and high technology and traditional light emitting effect: comparison, LED light source is low microelectronic products, successful integration of computer technology, network communication technology,Bluetooth keyboard device image processing technology and embedded control technology. The traditional LED lamp used in the chip size is 0.25mmX0.25nm, and lighting LED size is generally to be above 1.0mmX1.0mm. The LED bare chip forming the working table structure, inverted Pyramid structure and the flip chip design can improve the luminous efficiency, thereby making more light.

The LED package design innovations including high conductivity metal block base, flip chip design and bare disc casting type lead frame, using these methods are able to design a high power, low thermal resistance of the device, and the device than the traditional LED products illuminance illuminance greater.
