US Department of Energy’s CALiPER plans to release the latest report: white dimmable LED lamps for light color testing, which is also the first time the survey can color LED lamps. The main purpose of this study is to standardize the tests adjustable white LED light products for the test project. Under this premise, to define a clear specification, we must find the necessary testing program, and to explore the feasibility and broad applicability. The test were detected eight white dimmable lamps, mainly for different aspects of the test, including the color range (CCT) and dimming (flux).
The main testing report complete flux measurements, in a range of color temperature, a total of 11 benchmarks set point, if set reference point too, will be unable to detect the color temperature of the product as well as input, lumens, luminous efficiency, color shift difference Duv. Test results show that future test procedures may require at least 5-7 basis points to detect a clear product placement. Increase testing procedures may have formed the burden manufacturer, but can stabilize measurements by using a simplified process and shorten the measurement of different readings of the set time.
The report count a related problems existing detection methods, and the use of such products in the feasibility, in the short term to address these issues will be discussed. More details of the report can be to the United States Department of Energy Web site to download the full report.
