lled par38 (doe)

The U.S. Department of energy (DOE) recently announced the suspension of a better tomorrow lighting Award (L Award) project is intended as a substitute for LED PAR 38 halogen bulb lamp selection, this is the second time to suspend PAR 38 lamp selection, according to the Department of energy is introduced because of the recent products did not reach the required effect. For the L award, the Department of energy has revised some of the required options, but about 123 LM / W function requirements, DOE is based in the United States Congress based on the requirements, can not be modified.

Technical indicators L award is to continue to extend the solid-state lighting, led solid-state lighting (SSL) industry to achieve higher energy efficiency. PHILPS lighting in 2011 won the 90 LM / W performance requirements, it is presumed that directional properties of PAR 38 lamps, compared to the omni-directional A- lamp, should enable manufacturers to make more efficient products.

The United States Department of energy first suspended PAR 38 race in 2011, that does not meet the requirements of competition. In 2012, the re launch of the project match requirements to reduce the number of samples available light reduces the light output tolerances. Then in August last year, L awards will be the maximum beam pattern to expand the program from 12 degrees to 15 degrees. Nevertheless, the U.S. Congress authorized the effect of demand has remained the same, no company has hinted that the intention to enter the 38 competition PAR. The energy department report said, listed on the market of 38 PAR lights are far less than the target. In fact, the best product on the market, its efficacy reached only 90 lumens / watt range, the Department of energy to re evaluate the competition requirements.

The United States Department of energy said it would consider in the future to start PAR 38 competition, in addition, an act of Congress will also set aside $5 million to obtain PAR 38 L award issued by the company. In addition, the winner will have the opportunity to get the sale of large sums of winning lights to the U.S. government's orders.

In retrospect, it is not clear PHILPS lighting from a A- lamp L prize for how to get beyond $10 million profit. Of course, PHILPS is the leader in the transformation of LED lamp market, but won the L prize for the design of lighting in the market reaction is, although the L prize A- lamp is an excellent product, a heat sink and high unit cost obviously remote phosphor appearance, but it did not succeed in the market.
