LED Light Bulb

Our current data with experimental LED sources indicate a 20-50% improvement in distribution efficiency over conventional light sources. This result should not surprise any designers of luminaries. Hot sources require remote and large surfaces to shape the light distribution. High quality surfaces are expensive and low quality surfaces quickly dominate the light distribution efficiency. The same argument holds for 4ft FL lamps. The Surface of the lamp is cold, but very large.

The arguments of the above paragraphs bring us to an important prediction: During the 2015-20 periods, LED technology will drive lighting. Its value proposition of energy saving, lamp life even in extreme environments, maintenance, safety and a host of other beneficial features will make LED lighting a disruptive technology. In addition, LED lighting will bring a few other features to the table:

1. Practically unlimited dimming range without sacrificing efficiency.
2. Color control, not only along the white point line but, over the entire color gamut of the primary light sources.
3. Instant turn-on after a power failure (streetlights, sports stadiums).
4. Longer stand-by operation for a given battery size (emergency lights including dimming options).

This list could be extended by including the needs of a variety, of lighting applications. It only serves to demonstrate the unmatched and nearly universal lighting contributions that LED lamps will be able to offer.
