Reading and writing desk lamp is a kind of lamp widely used in lighting electrical products, especially the desk lamp claiming to protect eyes from learning, reading, comfort, eye moistening and other words is very popular, for example, if you log in to a shopping website and enter the words 'eye protection lamp', you will find that there are countless types of eye protection lamps coming out. This year 3. The exposure of the stroboscopic problem at the 15th party pushed the identification of the quality of reading and writing desk lamps to the forefront, making consumers confused about which type of reading and writing desk lamps to purchase. In order to master the quality status of desk lamp products for reading and writing and provide consumers with more scientific and fair product quality information, from December 2016 to February 2017, shanghai Municipal Bureau of Quality and Technical Supervision commissioned Shanghai Shidai Zhiguang lighting appliance testing Co. , Ltd. to evaluate the performance indexes of the reading and writing desk lamp products sold in the market, at the same time, Shanghai lighting appliance industry association was also entrusted to evaluate the test results of the evaluation. This time, we collected some desk lamp products for reading and writing, totaling 45 batches of samples, and did not pay attention to whether the enterprise had any claims. A unified standard method is adopted to evaluate the performance of the products, including light biosafety, flicker, illuminance, illuminance uniformity and color rendering index. On March 20, 2017, Shanghai Bureau of Quality and Technical Supervision announced the quality evaluation results of desk lamps for reading and writing in Shanghai in 2017. On March 31, 2017, the in-depth interpretation conference on the test results of the main quality indicators of reading and writing desk lamp products in Shanghai in 2017, sponsored by Shanghai lighting appliance industry association, was held in Shanghai Lighting City, representatives from the municipal quality supervision bureau, news media, manufacturers, sellers, consumers, and testing agencies attended the conference. The press conference was hosted by Huang Zhentao, secretary general of Shanghai lighting appliance industry association, yang Yue, deputy general manager of Shanghai Times light lighting appliance testing Co. , Ltd. , Professor engineer, Liu Lei, leader of distribution photometric testing group, and Huang Zhenyi, secretary general of Shanghai Times Light Lighting Co. , Ltd. , explained the performance index testing results of desk lamp products for reading and writing, sampling and testing procedures and evaluation of results. This product has collected a total of 45 batches of sample desk lamps, covering the main brands in the high, medium and low-end market, all of which are the top products in sales. 18 batches of desk lamps within 100 yuan, 100-200 yuan table lamp 16 batches, 200- 8 batches of table lamps in 500 yuan and 3 batches of table lamps above 500 yuan. Of the 45 batches of samples purchased for this evaluation, the product mark, instruction manual or webpage promotion page contains similar claims such as learning, writing, reading, eye protection, comfort, no stroboscopic, health, eye moistening, etc. Shanghai time light testing Co. , Ltd. uses a unified standard method to evaluate the performance of the product, including light biosafety, flicker, illuminance, illuminance uniformity and color rendering index. The test results are as follows :(I) Light biosafety GB/T 20145- 2006 The Light biological safety of lamp and lamp system stipulates the light biological safety risk level and measurement method of the lamp. After testing, 45 batches of samples meet the Photobiological safety requirements in the standard. Among them, the photochemical ultraviolet hazard levels of 10 batches of fluorescent lamp samples are all non-hazardous; The retinal blue light hazard level of 26 batches of LED desk lamp samples is non-hazard. Another 9 batches of LED table lamp samples are low risk (Blu-ray Class 1) When these table lamps are used, the direct light source should not exceed 100 seconds, which will not cause retinal blue light damage. (II) Flickering, all light sources working with AC power supply will flicker (That is, the stroboscopic that people often say) Therefore, there is no real desk lamp product without stroboscopic. Since the flicker of light source may bring negative influence on the health of users, IEEE Std 1789: 2015 'modulation current method of reducing health risk of users with high-gloss LED recommended by IEEE' recommends the measurement method, it also specifies the range of parameters that can be safely used. Of the 45 batches of samples tested this time, 41 batches of samples did not exceed the low risk after detection. (III) National standard for illuminance and illuminance uniformity GB/T 9473- 2008 the performance requirements of reading and writing desk lamps make grading requirements for the illuminance and illuminance uniformity of desk lamps used for reading and writing lighting. Of the 45 batches of samples tested this time, 1 batch met the requirements of AA grade and 12 batches met the requirements of a grade.
