Philips has successfully developed an LED bulb that can replace the ordinary household light bulb and submit it to the DOE for the 'L Prize' contest.
The US Department of Energy recently announced that it has won its first entry in the Bright Tomorrow Lighting Prize (L Prize) competition: a 60W LED bulb from Philips ELectronics that replaces incandescent lamps.
The 'L Prize' is the first technology competition sponsored by the US Department of Energy (DOE) to encourage lighting manufacturers to develop high-quality, high-efficiency LED products to replace ordinary light bulbs. The US Department of Energy's goal is to promote product quality and energy efficiency, while at the same time reducing the cost of the technology and thus being more widely accepted by the market.
The DOE previously announced that the 2007 Energy Independence and Security Act of 2007 was enacted, prompting DOE to set up the Bright Tomorrow Lighting Prize (L Prize) in May 2008.
Legislation poses a challenge to the lighting industry, requiring the development of lighting products that can replace 60W incandescent lamps and PAR 38 halogen lamps as soon as possible, while developing "new 21st century lighting products."
The product submitted by Philips will undergo a rigorous and extensive evaluation, including performance testing led by independent laboratories, on-site assessments involving common utilities or other partners, and long-term lumen maintenance testing and loading under extreme conditions. Test, etc.

At the same time, DOE said they want more companies to participate, whether they are large companies or small companies. Participating companies can participate in different competitions according to different product types until one winner is announced. Winners will receive cash prizes and prizes from other sponsors.
Winning the L Prize is not an easy task. It must meet the stringent requirements set by the DOE, including performance, quality, longevity, cost, usability, and be suitable for large-scale promotion and high-volume manufacturing requirements.
In addition to the cash prize, the first winning company that fully meets the requirements of the competition will receive a federal purchase agreement, public project or other incentive prize. According to DOE, there are already 27 public utilities and energy efficiency organizations joining the 'L Prize' sponsors, who have agreed to work together to reward the winners of the L Prize competition to help promote and deploy award-winning products.
At present, DOE's requirements for replacing 60W incandescent LED bulbs include:
???The luminous efficiency exceeds 90 lm/W, which exceeds all current incandescent lamps and most compact fluorescent lamps.
??? Energy consumption is less than 10 watts (compared to a 60W incandescent lamp)
??? Light output exceeds 900 lumens, equivalent to the brightness of a 60W incandescent lamp
???CRI index exceeds 90
???The color temperature is between 2700K and 3000K, which can emit the same warm white light as incandescent lamps.
Currently, 425 million 60W incandescent lamps are sold each year in the United States, accounting for about half of the national incandescent lamp market. The DOE estimates that if replaced with LEDs, that year will save 34 terawatt-hours (Taiwatt hours), enough to support the annual lighting needs of 17.4 million American households. In addition, it will reduce 5.6 million tons of carbon dioxide emissions every year.
