The future for commercial LEDs

New advances in transistor technology can help create LEDs that provide a large light source at an affordable price.

>>> The lights are still on despite the power failure

Despite its reputation for durability and low power consumption, it is in the case of conventional lighting. At high speed, high frequency current semiconductor systems make LEDs become expensive when applied to commercial. To overcome this disadvantage, scientists at the Fraunhofer Institute (Germany) are developing high performance LEDs with gallium nitride .

The research team led by Dr. Michael Kunzer produced the gallium nitride driver with an efficiency increase of over 86%. Gallium nitride transistors can convert up to 10 times faster than traditional silicon LEDs, which makes the new generation LEDs cheaper. , smaller and more durable.

Gizmag Magazine said the new generation LEDs are made of materials and accessories available in Germany. Its expected efficiency will exceed energy saving lamps by 2015. Older incandescent bulbs already banned in the EU and halogen lamps are also facing an uncertain future, so this is the muscle. Good match for LEDs to fill the void.

According to Gizmag, an incandescent lamp can last up to 1,000 hours. Fluorescent lamps are available for 8,000 hours and LEDs last between 15,000 and 30,000 hours.
