Taiwan Delta Electronics has rolled out a serious of LED products at Lighting Japan 2012.

The company claimed that it has developed the world's lightest 1000lm light bulb weighting only 130g .With a beam angle of 120 deg and 240 deg the new bulb aims to replace 100W and 80W incandescent bulbs.

In the meanwhile, Delta is also demonstrating its remarkable solar-LED streetlight and wind-powered LED streetlight solutions. The wind-powered LED streetlight solution includes a 400W-system with a safety breaker for wind speed exceeding an upper limit of 42.5m/s and a programmable controller.

The wind turbine generates 400W at a wind speed of 11m/s and may power up to 1300W to light up an LED streetlight of 6000lm. The entire system conforms to IP65 standards and may be dual-powered by both wind and the city power grid.

The solar-LED streetlight solution includes a solar panel to power a 5500lm LED streetlight that has an analog programmable dimming function. A 150W solar power input can support such a system of 90lm/W for three days autonomously.
