Thanks to the Hong Kong Polytechnic University Electronic and Information Engineering, researchers recently developed high-performance LED driver , LED lights can be brighter and more energy-efficient than ever .

This award-winning high-efficiency technology can be applied in many fields, such as LED billboards , and another 15% energy saving

The new drive use the innovative multi-stage PWM technique to supply power for the LED lights , compare with the the PWM and linear drives LED products currently use , this kind of technology significantly improves the quality of light and energy efficiency. This approach is not limited to the LED driver , and can provide more benefits and options than the PWM or constant current mode.

Using the traditional PWM method , what the current LED accept is pulsed, rather than DC . This drive current fast switch with the speed the human eye can not detect. The Pulse current supply to the LED so that the optical output is more easily controlled.

The research team was established by the Doctor Lai Yuk Ming , Professor Loo Ka Hong Dr. and Michael Tse, they have changed the PWM mode . Pulsed operation is redesigned in the way that is maximize the light output while minimizing thermal energy . Resulting in higher luminous efficacy (lm / W). Dr. Loo Ka Hong thought their technique could be saving 15%.

In large-scale applications, the energy-saving effect is more significant. One Times Square building in New York billboard is a good case . 12 million lights were used in the huge display of the Building, the power is 250KW. If the billboards work for 16 hours a day , then the monthly electricity bill is $ 18,000 . Energy savings is 12% ,which means that $ 2,160 .

Moreover, compared with traditional methods , which require low heat dissipation , the required heat sink is smaller. This means that the LED system can be made smaller . As with excellent dimming capability , the new PWM driver allows the manufacturer can produce a full dimming LED, thereby leading to as low as 0 watts dimming performance . These excellent quality can create the brighter and more intelligent and more durable LED lighting solutions.

Worldwatch Institute said that from the perspective of environmental protection , the world are turning to LED era. If all of the traditional lamps are replaced with energy-saving products , lighting energy will be reduced by 40%.

As most green light replacing the incandescent, LED is popular choice for the lighting , but it is not perfect . Consumers need brighter and more natural light , as the same as the incandescent.. For the high power applications such as the automotive headlamp lighting and buildings lighting ect , the demand for brightness is even more prominent. Global LED industry are worth trying . Multi-level PWM method is a exciting technology industry

Obviously , this new technology can create a better product. High luminous performance and good thermal protection allows manufacturers to make more compact exterior lighting solutions , and lumen output is very high. Moreover , the cost can be reduced , because all of these quality can be obtained by means of this low-cost IC . This is big happy event for the LED manufacturers.

The technology industry has caused strong concern and won the Gold Meda in 41th International Exhibition of Inventions in Geneva, Switzerland on April lst 2013.
