8 tile energy-saving lamps than two sets of incandescent lamp 25 tile brighter
Experimental Location: Zhejiang Province, lamp testing center
Experiment time: February 8, 2008 at 1:30 pm to 5 point semi-
Special cooperation unit: Ningbo City Product Quality Supervision and Inspection Institute for Electrical and Electronic Testing Center (Zhejiang Province, lamps testing center)
Subjects: 25W incandescent, 60W incandescent lamp, 8W energy saving lamps, 14W energy-saving lamps each one (branch).
Laboratory personnel: lighting inspectors Zhuliang Kang, Mao Shunsheng
Experimental environment: temperature control in the laboratory about 25 degrees Celsius
Experimental background
November 4, 2011, the National Development and Reform Commission and other departments announced the phasing out of incandescent power level road map to promote energy-saving lamps, and decided that from October 1, 2012, according to the power of the size of a phased gradual ban on the import and sales of general lighting incandescent. Which, from October 1 this year to prohibit the import and sale of 100 watts and above general lighting incandescent.
So, compared to incandescent, energy saving lamps in energy consumption, light effects What are the advantages? Energy-saving lamps to replace incandescent lamps in the end is to "make" or "lose" it?
To answer the public's many doubts, and the current livelihood Laboratories is located in Cixi of Ningbo Product Quality Supervision and Inspection Institute for Electrical and Electronic Testing Center (Zhejiang Province, lamp testing center), specializing in energy-saving lamps and incandescent scene comparative experiment.
The first experiment
8W energy saving lamps more than 2 times the brightness equivalent to 25W incandescent
Experiment: the light source in the industry testing standards, professional testing equipment, energy-saving lamps 8W and 25W incandescent detection, draw the corresponding luminous efficiency data.
Inspectors first incandescent lamp on the warm-up equipment to warm up for 15 minutes, 15 minutes in the 220V voltage power. Then the energy-saving lamps on the warm-up equipment, preheat 25 minutes, 25 minutes in the 220V voltage power.
Then the energy-saving lamps and incandescent lamps were removed, the spectrum of radiation into the light source photoelectric color test system in the analyzer: a diameter of about 2.5 m integrating sphere for 20 minutes of light effects.
Results: after 20 minutes, draw the corresponding luminous efficiency data. 8W energy saving lamp luminous flux of 461.5lm 25W incandescent lamp luminous flux is only 214.8lm power of 25W incandescent equivalent to more than three times the 8W energy saving lamp, but the actual luminous flux in turn less than energy-saving lamps per a.
Second experiment
14W energy-saving lamps 60W incandescent "light" one more than half
Experiment: the light source in the industry testing standards, professional testing equipment, 14W energy-saving lamps and 60W incandescent detection, draw the corresponding luminous efficiency data.
Experiment with a similar experiment.
Results: after 20 minutes, draw the corresponding luminous efficiency data. Up 892.7lm luminous flux of 14W energy-saving lamps, 60W incandescent lamp luminous flux is only 538.8lm power of 60W incandescent equivalent to more than four times the 14W energy saving lamp, but 60% of the actual luminous flux in turn, only energy-saving lamps.
