Sales LED lights unqualified containing seventy percent injured eye 'gutter powder'

Yesterday, the jiangsu province pledges inspect bureau announced in local production of jiangsu province and jiangsu market in the sampling of the sale of LED lamps, energy-saving lamps, according to the result analysis of the current sampling and four major problems of the two kinds of market of lamps and lanterns. Sampling results show that jiangsu local production of LED lamp and energy-saving lamp quality is better, but the leds that sells on the market the percent of pass is only thirty percent, a little more energy-saving lamps in the percent of pass is fifty percent. In addition, qualitative inspect branch in the sampling inspection found that some inferior energy-saving lamps may be used 'gutter powder' ( Recycling of waste powder), Carry on the processing of an illegal approach, the inferior lamp not only dimly lit, also hurt the eyesight. Result of sampling observation of

thirty percent energy-saving lamps unqualified

introduce quality supervision department, after they were checking the 103 batches of LED lights, 53 batch production areas, the 50 batches that sells on the market, basic covers the mainstream brands and varieties on the market. Test results show that jiangsu local production in the field of LED lamps and lanterns percent of pass is 88. 7%, while sales of LED lights on the market, percent of pass is only 30%, there are more quality issues.

in the energy-saving lamps of sampling, a total of 85 batches of 59 batch of qualified products, the overall qualified rate is 69. 4%. Production in the field of energy-saving lamps selectived examination 35 batch, percent of pass is 94. 3%. And sales of energy-saving lamps on the market situation is not very desirable, 50 batches of sampling observation, only 26 batches of qualified, percent of pass is 52%, just over half.

qualitative inspect branch relevant controller introduces, at present there are all kinds of jiangsu lighting electric appliance enterprises more than 2000. Jiangsu province is not only one important LED production base in China, there are many production of energy-saving lamp enterprises, mainly distributed in yancheng, changzhou, yangzhou, wuxi, suqian, etc.

why poor market sales of product sampling percent of pass? Electric light source products in jiangsu province quality supervision and inspection center engineer Liu Yu analysis, first of all, the provincial unqualified energy-saving lamps that sells on the market price is much lower than the enterprises in the province of production cost, second, many unqualified products production enterprises on the market is a lot of small businesses and even small workshops. The third is the 'export factors', large and medium-sized enterprises of most products for export. Liu Yushui, those small enterprises on the market, small workshops, production of 'quality and content not beauty' of energy-saving lamps products market share constantly diverted, the 'bad light after bad light' phenomenon, form a vicious circle.

detected problems

inferior energy-saving lamps may use 'gutter powder'

in selectiving examination this time, zhongshan ou point lighting co. , LTD. , zhongshan guzhen court one hin lighting electric companies such as the production of 20 batches unqualified product initial photosynthetic efficiency. Liu Yushui, initial photosynthetic efficiency is about 'energy conservation and the light is not bright, energy-saving lamp energy saving energy saving' problem, in general, the higher the value of the initial photosynthetic efficiency, the brighter the light, the more energy-saving.

Liu Yushui, in selectiving examination, they had to promote 'gutter powder' of personnel, the unqualified initial photosynthetic efficiency may be able to find the answer.

Liu Yu introduction, 'gutter powder' is the recycling waste powder, some businesses also use cheap ordinary halogen powder, but in fact, should be used in the process of normal production is the standard requirement of 'three primary colors' rare earth phosphors. Allegedly, small businesses in pursuit of low prices and the cost of compression, so can use 'gutter powder', 'cooking powder sales people from zhejiang, we meet said they use gutter powder is a kind of hidden rules. '

Liu Yushui, powder' gutter 'to the initial photosynthetic efficiency is unqualified, not only dimly lit, vision, and life is very short, neither electricity nor money.

leds detection blu-ray harm

LED selectives examination, found that there are 5 batch product class 1 blue light. Spot check of jiangsu estate light biosafety LED lighting products are qualified.

the leds generally no ultraviolet and infrared spectrum, but the blue component under certain conditions will the networks of nerve damage to people.

in general, for the LED blue light 1 kind of harm, Low risk) In terms of general use distance is greater than 1. 5 meters, or use for a long time ( Generally less than 2 - 3 hours) No harm to person.

some energy-saving lamp power 'artificially high'

Liu Yu told reporters, the modern express evaluate whether a lighting products such as energy saving performance index is usually use lamp power, electric power conversion efficiency, such as lighting effect index to evaluate.

according to introducing, this sampling, there are 21 batches the lamp power of the product is unqualified, existence of 'qi'. Liu Yu is introduced, some enterprises will deliberately low power light called high power lamp, the purpose is to sell the lamp of small power of high power lamp price, profit, this will let consumers to spend money.
