The development features of high
power LED lighting and trend analysis
The illumination application is main target with the development of
high power LED light, although generally recognized that at present LED
entered the general illumination domain still have a certain threshold,
but with the functionality illumination application's rapid development
in landscape illumination, LCD back lighting applications, miner’s lamp
and street light. High power white light LED still maintain very fast
development speed in technical specification's promotion and expansion
of application scale, the development speed of high power LED will keep
above 50% in the future several years.
As the application fields and market expansion, the high power
LED’s development characteristics and trends are having some
changes and
showing some new industrial characteristic:
1. The mainstream product LED price reduces gradually
Currently, 1W white LED products with Cree production luminous flux
70~90lm, market price maintains basically about 17 Yuan, the same type
PhilipsLumileds product price about 19~21 Yuan. China Taiwan 1W white
light LED (luminous flux 70~80lm) selling price about 10~15 Yuan. The
high-power LED adopting import chip in the mainland, its price stands
at the same line with Taiwan, the high-power LED’s price basically
about 5.5 Yuan in domestic.
At present, ability mass supply the white light LED power component
manufacturer still limit in Ruifeng electronic, the country star
electro-optic, Guangzhou Hongli and Taiwan yilighting, Guangbao and
other manufacturers. Along with the fast growth of the power white
light LED application and the unceasing upgrade of luminous efficacy,
it estimated that its sign LED price will reduce gradually.Costs and
heat dissipation still is the biggest obstacle in LED replacing
traditional lighting
The LED most attractive application field is illumination, the cost is
very essential for the LED substitution tradition illumination.
Although the price relative to its LED double the life of the
traditional lamp is not high, and can save the replacement and
maintenance costs, but the outset expense directly is often restrained
the purchase budget. Phillips thought that the main bottleneck of
influence present LED application lies in the lumen cost higher 10
times than tradition lighting source. So must improve the light
efficiency to 150lm / W, the drive current enhances from 700mA to 2A,
at the same time the tube core and the seal expense must reduce half.
If we can do above all, it will have a large-scale universal
application in the illumination domain.
Ministry of Industry and Electronic Information Division indicated that
LED encapsulation is make light and the heat together in one component,
and heat will bring the biggest impact to LED component, if always
realizes the illumination in the high temperature situation, it will
affect enormously the illumination component or lamps and lanterns'
life, therefore putting forward the stern challenge in the seal
structure aspect for the LED illumination.
High power LED market using prospects for domestic At present, the
landscape lighting market is the largest application market for high
power LED illumination,
