DOE announces LED lighting demonstration project report and test results

Report on demonstration project of using LED lighting in parking lot

The United States Department of energy (DOE) has announced a LED demonstration project in Western California, Sacramento, Raley supermarket parking lot installation of double LED lamps.

This demonstration project report (GATEWAY demonstration report) by Pacific Gas and electric company (Pacific Gas & ELectric) and Energy Solutions company to prepare for the project test results made a summary, including lighting performance, economic benefit and energy saving potential.

In this project, Raley supermarket parking lot with LED lamp, LED lamp which is provided by the BetaLED, and with double level controlled by motion detectors, replace some metal halide (MH) lamps.

Comparison of metal halide lamp and LED lamp

The results of the survey: the average power of high-power LED lamps is 149W, the average power of small power LED lamps is 52W, compared with the power of 346W halogen lamps, LED lamps are expected to average annual energy savings of nearly 70%. High power and small power LED lamp light is uniform, which is better than the metal halide lamps. Simple calculation of the use of LED lamps return on investment, for the new building and construction of the transformation of the dual level work of LED lamps in return for less than 5 years.

CALiPER project seventh round test results

The United States Department of energy has completed the seventh round of the CALiPER solid state lighting project product testing, including outdoor lighting lamps, lamp and lamp replacement.

Pre Qualification Statement for stress testing

The U.S. Department of energy also requires the ability to declare, for the purpose of pre - research facilities, and / or pre - development of integrated LED lights and pressure testing laboratory.

Qualified agencies will be able to develop and implement a variety of test procedures to assess the performance of a specific integrated LED lamp in a variety of working conditions, and to identify the failure mode, and reduce the occurrence of such failures.

Two factors have been taken into account, such as sudden failure and reduced performance (light output, apparent color change, and change in the distribution of luminous intensity).

The implementation of the stress test will support the launch of the DOE solid state lighting program, which is associated with the CALiPER project test and the L (L) (TM) competition. Prior to the award winners, the entries in the L prize contest must meet stringent performance requirements and undergo rigorous photometric, life testing, and stress testing.
