Led-World Exclusive - All-LED-lights Mercedes-Benz CL on 2011 Shanghai Auto Show

"Innovation for Tomorrow" is the slogan of the fourteenth session of the Shanghai auto show. Based on this concept, the auto show brings many new technologies to the first facing the public. Mercedes-Benz CLS enjoys its debut on the auto show. Its 71 LED lights design makes it the focus. 2011 Shanghai Auto Show

LED has been used in automotive lighting for some time, but now there are only two kinds of vehicles applying the all-LED headlights: Mercedes-Benz CLS and Audi A8. According to manufacturers, those Audi A8 sales domestically use Xenon headlights and all LED lights are only options. Then here are the questions: What about all LED headlights? Will them become the future mainstream?

Currently, a single LED light source intensity is still less than xenon lamps. Among the majority of the car lights, LED lamp only plays a supporting role for Xenon Headlights. To reach the same brightness, even high-brightness LED requires an additional group LED lights comparing with the xenon lamps. And this group of high-brightness LED costs much and release much more heat than xenon lights.

However, the manufacturers tell us that, through some special power conversion device, LED light can issue different color temperature. The car headlights of Mercedes-Benz CLS can transform the color temperature under certain conditions and can be used as fog lights. Audi A8's daytime running lights can be converted into turn signals.

At present, LED lights have been widely used as auxiliary lights for vehicles. In turn lights, fog lights, and many other places LED Lights have replaced other sources. However, the high cost of LED brightness and thermal are the problems that R & D personnel facing. LED lighting as the main front Car Headlights is still immature. If this bottleneck breaks, LED will be the future of the automotive field.

Now, if you want to replace your car headlights, HID Xenon Car Headlight Kits are still your best option. They are providing driver better visibility and nigh vision for safety concern. is a professional wholesaler and dropship supplier of Car Eletronics. The products are now at low China wholesale price for all its clients.

Philips introduces 75W equivalent LED light

Philips claims that the new lamp will create light that will be indistinguishable from a standard incandescent light bulb.

LED lamps are expected to revolutionize the lighting industry because of their sharply reduced power consumption and their long life compared with standard incandescents. But to date, market acceptance has been slow given the high initial cost and limited brightness. LED lamps have only been able to emit light equivalent to a 60-watt standard bulb.

On Friday, Philips will look to change that game by announcing that it will market an LED lamp later this year whose light output equals that of a 75-watt incandescent.
The bulb, the EnduraLED A21, will retail for about $40, last 25,000 hours and produce 1100 lumens of light by consuming just 17 watts of electricity. (A standard 75-watt lampfrom GE produces 1170 lumens.)
Over the life of the lamp, Massachusetts consumers will save $300 in electricity costs alone and will break even in 1.6 years.
"The trick with an A lamp is how to project 1100 lumens in 360 degrees," said Ed Crawford, general manager of lamps for Philips Lighting, North America. "It's absolutely more difficult to do 1100 lumens in an omni-directional lamp."
To accomplish that, the new lamp, available around September or October, contains 18 LED modules fixed in multiple directions. Various metal fins surrounding the lamp are used to dissipate heat.
