US or to subsidize led tube lights

Sep 15, 2017

The person's visual effect is soft and uniform. Energy-saving: the same brightness power consumption for ordinary energy-saving lamps 1/2.

The U.S. Department of Energy recently released a new caliper snapshot report on LED tube lights, confirming the trend of last year's forecast. The report notes that while manufacturers have been improving the light quality of this type of product, the average efficiency has increased by only 1 LM over the past 15 months, indicating that the effectiveness of such products has stagnated. In terms of funding, the Department of Energy announced 11 new research and development grants, 10 of which were in the "Small Business Innovation Research Program (SBIR)" and the other in the "Small Business Technology Transfer Program (STTR)", both of which are key developments in the field of solid-state lighting. 

Tube Lamp Performance

Just a year ago, the U.S. Department of Energy released a report on the caliper snapshot of LED tube lights. Unexpectedly, another such report was published so quickly this year. But it is clear that the Department of Energy is concerned that the energy-saving gains in the tube-lamp industry have been stagnant. In 15 months, the dark light trough energy-saving gain 7 LM, industrial lamps for the LM, linear lamps for ten LM, wall lighting devices for the LM, decorative lighting for 5 LM, compared with the same period, the tube lamp only 1 lm. In addition, the average effect of the tube lamp is LM, while the average efficiency of many other products mentioned above is close to or above $number LM.

There is no clear reason why solid-state lighting manufacturers cannot achieve the same energy-saving effect as ordinary LED lights. The US Department of Energy says the tube lamp is the first indoor area where led sources are rapidly exceeding traditional light sources in light and quality. Manufacturers may be more focused on reducing costs than on boosting efficiency.

But the U.S. Department of Energy is not only worried about missing energy opportunities. The report points out that improving the effectiveness of LED sources can simplify thermal management, thus providing greater flexibility in design and appearance. These factors may also reduce costs.

New Sbir and STTR schemes funded

In the area of research and development funding, the Department of Energy's recent rewards are designed to help the industry develop in tandem with its solid-state lighting development program. These rewards once again cover OLED and LED technology. Although the lighting industry does not seem to be so satisfying, the U.S. Department of Energy still believes that OLED sources will fill important gaps. The U.S. Department of Energy continues to invest in solid-state lighting, including other funding for the 17 fiscal year announced in January. A recent report by the American Academy of Sciences says solid-state lighting research and development programs play an important role in lighting, allowing the industry to move more quickly towards the LED lighting industry.
