LED using cold light source, small glare, no radiation, no use of harmful substances. LED's
operating voltage is low, DC drive, ultra-low power consumption (single tube 0.03~0.06W),
electro-optical
traditional energy sources more than 80%. LED's environmental benefits of better, no
ultraviolet and infrared spectra, and recyclable waste, no pollution, no mercury elements,
safe touch, typical of the green lighting.
Long Life
LED is solid cold light source, epoxy resin, anti-vibration , light body and no loose parts, there is no
filament light easy to burn, heat
deposition, the light fades and other shortcomings, the service life
of up to 60 000 to 10 million hours, more than 10 times the life of traditional light sources. LED
performance and stability, can work normally under -30 ~ + 50℃ environment.
Multi-transform
LED light source can make use of red, green and blue color theory, under the control of computer
technology to make three colors with 256 gray
scale, and any mix, you can generate 256X256X256
(ie 16777216) colors to form a different light combination of colors. LED color changing light
combination can achieve a variety of dynamic effects and variety of images.
The High-tech
Compared with conventional light sources glow, LED lighting is low voltage microelectronic products,
the successful integration of computer technology, network communication technology,image
processing and embedded control technology. Chip size used in conventional LED lights for
0.25mmX0.25nm, and LED lighting dimensions are generally required in 1.0mmX1.0mm more.
Working Desktop LED die molded structure, inverted pyramid structure and flip chip design can
improve the luminous efficiency, thus sending more light. LED package design innovations include
high conductivity base metal block, flip-chip design and bare disc casting lead frame, etc. These
methods can design a high-power, low thermal resistance of the device is,
and illumination of these
devices than traditional LED greater illumination products.
At present, a typical high-flux LED device can produce a few to tens of lumens lumens, updated
design can be integrated more LED in a device,
or install multiple devices in a single assembly,
so that the number of lumens output the equivalent of small incandescent lamps. For example, a
monochromatic high-power LED chip 12 can output light energy 200lm device, the consumed power
is between 10 ~ 15W.
Application of LED light source is very flexible and can be made of points, lines, surfaces of various
forms of portable products; controlled LED is extremely convenient, as long as the adjustment of
current, you can freely adjust the light; great variety of different combinations of light and color,the
use of timing control circuit, can be better achieved a variety of dynamic effects. LED lighting has
been widely used in various devices, such as battery-powered flash, miniature voice-activated lights,
security lights, outdoor and indoor stair lighting roads and buildings and marking continuous
lighting.
The emergence of the white LED is a substantial step from identifying features LED lighting function
taken to the. White LED closest to the sun, more better reflect the true color of illumination of the
object, so from a technical point of view, LED white LED is undoubtedly the most sophisticated
technology. Currently, the white LED has entered a number of application areas, emergency lights,
flashlights, flash and other products
have come out, but because the price is very expensive, and
therefore difficult to spread. White LED universal premise that prices fell, while prices in white LED
must be of a certain size of the market after the possible integration of the two ultimately depends on
technological progress.
