U.S. Department of Energy announced the seventh round of tests CALiPER project has ended

In Electronic Infomation Category: R | on January   17, 2011

U.S. Department of Energy (DOE) commercially viable LED Product Evaluation and LT1039CN16 datasheet and Reporting (CALiPER, Commercially Available LED Product Evaluation and LT1039CN16 price and Reporting) program of the seventh round of testing has been completed.

Seventh round of testing a range of products mainly include three application areas: outdoor lighting, downlight and LT1039CN16 suppliers and replacement lamps.

The test report covers the key point is a "steady increase in luminous efficiency, color quality, power factor, and product manufacturers to accurately report on the SSL. Unfortunately, there are various on the market today products showed a greater difference in performance, the test results show that the effect of outdoor light street SSL is 19-71lm / W range, but, SSL downlights light efficiency is 9-48lm / W range. "

The accuracy of manufacturers product specifications

CALiPER project in the seventh round of tests, compared with the previous rounds of testing, we can observe that there is more accurate and complete performance report. However, the report said that 50% of the tested products that are inaccurate or performance expressed the full situation.

Test details

Seventh round of tests started from September 2008 to the end of January 2009, a total of 29 products tested, displaying a wide variety of product types and technologies.

One of a series of tests, including 8 street: 5 SSL lamps, 1 species typical high-pressure sodium lamps, and two for fluorescent lamps. For outdoor lighting, CALiPER project also tested three kinds of guardrail lamps lamps: semiconductor lighting, compact fluorescent and metal halide.

The report said, "another series of test objects are 9 Downlight (8 uses SSL, 1 species using compact fluorescent (CFL)), consists of a series may be suitable for downlight luminaries, including : tunnel lights, veneered lamps, recessed downlight, and a 2 x 2 inch flat-panel lighting and so on. replacement lamp, including 9 different SSL products, alternative products, including: MR16s, some of the larger light ( PAR20, PAR30, and PAR38) and A-light. "

Conclusion

Light rails: "Take two similar products using different light sources were compared side by side, can appear convincing results. The used fluorescent lamps, metal halide (MH), and SSL in the light rails directly compared to SSL can be found in the lamps used for the CFL and MH than in the better light efficiency of lighting. "

Street: "A series of tests for outdoor lights to show the performance characteristics of a wide variety of lighting: the efficacy of such lamps, light output, light distribution and color characteristics."

Downlight: "By the early CALiPER downlight test, coupled with down light on 9 different test results, it is clear that they have the same light output, but efficiency SSL products, more than incandescent and halogen light products, light efficiency, and most of SSL products to the light directly with CFL downlights to compete effectively. "

Replacement lamp: "While many are still faced with SSL replacement lamps Performance description is inaccurate or insufficient color quality problem, but some tested replacement lamps, and low power compared to incandescent and halogen lamps, remain competitive Force. "
