The Chinese Consumer Association jointly established the Consumer Rights Protection Committee of Jiangsu Province, Zhejiang Consumer Rights Protection Committee and the Zhejiang Taizhou Consumer Rights Protection Committee launched a comparison test of reading and writing lamps in the first half of this year. The results show that in the 73 samples, only 12 sample test indicators are good.
This comparative test sample involves 51 brands, a total of 73 samples, including 46 domestic brands, 5 foreign brands. 36 purchases online, 37 shopping online shopping malls, supermarkets and wholesale markets. 58 is a movable plug-in lamp, 15 is a movable chargeable table lamp. 70 are LED light sources, 3 are self-swamp fluorescent lamps. 65 is a touch-switched switch, and the sample unit price is from 30 yuan to 1649 yuan. The detection unit is Changzhou Standard Quality Inspection Co., Ltd.
This comparison test mainly detects two aspects of safety and performance. Security items include: markers, structure, anti-electric power protection, blue level; performance items include: power cord, light shielding, illuminance and illumination uniformity, color temperature, general color index, flicker, product information. For the chargeable lamp, the capacity test of the rechargeable battery is also increased, and the high temperature external short circuit is added, and the battery ID requires three projects.
After testing, only 12 sample test indicators were good in 73 samples. All samples of anti-touch electricity protection and Blu-ray test items are in line with safety requirements. 19 samples are not complete, and 9 sample structures have security hazards. 14 sample power cords are less than 1.8 meters, which is inconvenient to use. The 2 samples are not smooth, and the formed glare is easy to harm the eyes. 45 sample illuminances or uniform illuminance is not good, which will affect the sharpness and comfort of the lighting, which is easy to form visual fatigue. 24 sample color temperatures are not within reasonable scope, affecting the use of comfort. The general color color index of 9 samples is low, affecting the correct display of objects, which may affect visual comfort. 69 sparkling performance is good, and there is no significant impact level. 2 samples are low-risk levels, and 2 samples are high risk levels. 29 sample product information is incomplete, not conducive to purchasing and use. In the 15 charging table lamp, there are 5 samples of the battery capacity below the promising value. A sample fails to short-circuit testing through high temperature, there is a safety hazard. There are 3 samples of the battery logo in complete.
The Zhejiang Consumer Protection Committee suggests consumers, and should pay attention to the following 7:00 when purchasing the read and write lamps:
First, select the product of the fully fully equipped. The logo is an important information and basis for relationships safe use and maintenance table lamps. Read the desk lamp itself and the package and the instructions, to mark the type of light source required, general color temperature, color temperature, manufacturer, production address, product specification model, and 3C certified logo. To avoid purchasing products that are not annotated.
Second, try to choose the product to purchase illuminance and illuminance uniformity indicators to reach the product. When you purchase, you can sit in the normal read and write position, you can see if there is a glare glare, etc., can read clearly and comfortably. The lighting on the desktop should be relatively uniform, and the lighting area should cover the scope of the read and write job.
Third, children use table lamps, try to use high color index lamps, general color color index is not less than 80. If you select a desk lamp of the low color index, the color reflected in the eyes of the child will lose saturation, resulting in color distortion, which is easy to cause visual fatigue, which may cause myopia.
4. Avoid using exposed LED light sources, exposed LED light sources will direct light, possibly damage to vision.
5. Try to avoid choosing a glossy desktop, because the glossy desktop reflects the brightness of the lamp, reflecting glare may cause visual fatigue.
6. To select a product suitable for color temperature, select the color temperature value labeled, choose no more than 4000K products.
Seven, press and need to purchase according to the environment. The plug-in lamp is not limited to the use time limit, the use efficiency has a long service, the unevenness of the illuminance will be more stable, and it is more suitable for reading and writing; the mobile charging reads the desk lamp, which is small and easy to carry, but the use time will Battery capacity is limited and experience will be greatly reduced.
