Japan's Sharp Corporation announced it will begin sales of two types of new lighting systems that integrate solar cells and high-intensity, energy efficient, long-lasting and mercury-free LEDs (light emitting diodes).

One of the products is called Lumiwall, and is scheduled for release on November 1, 2004. This is a translucent glass wall into which thin-film see-through solar cells and LEDs are built. The thin-film solar cells enable light to shine through during the day while at the same time generating electricity using sunlight. At night, the built-in LEDs provide illumination using the stored energy.

The other is a solar-powered lamppost for street lighting, scheduled for release on September 15, 2004. This streetlight does not require installation of power cables, either overhead or buried. As a free-standing lighting fixture generating its own electric power, it can operate even in cases of power failures due to natural disasters or other power outages.

Sharp has been the world's leading solar cell manufacturer for four consecutive years. These two products will serve as the first step towards the development of lighting systems that combine solar cells and LEDs.
