The RPI lighting research center announced solar LED road lamp field test results

The United States at rensselaer polytechnic institute, RPI) The lighting research center ( LRC) Field test results released the LED street lamp, the test site is located in the northern state of New York suburb of business parks. Field studies not only confirmed the LED street light energy efficiency, and volunteers in the survey the evaluation results of LED street lamp light source is equal to or better than that of the high intensity discharge ( 藏) Street lamp.

American suburbs in upstate New York business parks along the road of the LED street lamp

the study was conducted under the lighting research center of the DELTA project, the DELTA project is administration by the New York state energy research and development ( 能源研究与开发局)都知道,它 Development. The northern city of DELTA project evaluation for the Greenbush installation construction of office buildings around three bending street 16 BetaLED Edge LED street lamp. Test lamps rated correlated color temperature ( 有条件现金转移支付) Rated at 6000 k, color rendering index ( 中国国际广播电台) More than 70.

Edge LED lights article integrated modular LED lamp. Up to the standard of lighting lamps and lanterns of each article the installed lamp need to conform to the required number of light output. Used in the DELTA test the lamps and lanterns of the article contains three lights, installation height of 30 feet, spacing in 130 - 180 feet.

compared with the high pressure sodium lamp installed in the same business park, the purpose of the DELTA study is to test the quantitative measuring system performance, photometric performance, save energy and light pollution. In addition, the DELTA project and the participation of volunteers, can participate in the evaluation of LED street lamp.

26 volunteers LED street lamp average tested results

each LED street lamp power is 79 w, compared with high pressure sodium lamp, LED lights consume 38% of its electricity, under high pressure sodium lamp. The DELTA test using lighting analysts' software to calculate the road hundreds of feet along the LED street light illumination, the analysis results show that high pressure sodium lamp system lags behind that of the LED street lamp system on uniformity.

the DELTA test using fixed-point lighting outdoor function ( 百 The light pollution of computing technology ( Developed by lighting research center) To compare two kinds of lamps and lanterns. In terms of creating less light pollution, LED lamps and lanterns is superior to high pressure sodium lamp. DELTA researchers attributed the difference between the two to high pressure sodium lamp than bright LED lamps and lanterns, can better control the light at the scene of the test.
