As the National Development and Reform Commission announced that the policy of banning the sale of incandescent lamps of 100 watts or more from October 1, 2012 is approaching, the LED lamp industry is supported by relevant national policies, and traditional lighting has gradually transformed into LED lamps.
In the period of incandescent lamp delisting and other lighting replacement, in fact, consumers are not absolutely resistant to LED light
s, but dare not rashly accept them.
At present, the product identification in the LED market is unclear and unclear, and there is also a lack of uniform standards.
In the face of uneven products, the Guangdong Provincial Bureau of Quality and Technical Supervision recently conducted a random inspection of LED lamp products.
According to the random inspection of 21 Self-ballasted LED lamp products produced by 21 enterprises in 7 cities including Guangzhou, Shenzhen, Zhuhai, Foshan, Zhongshan, Huizhou and Dongguan, a total of 23 batches and 17 unqualified batches were inspected, the qualified rate is less than 30%.
It is understood that there are many and scattered LED market enterprises at present, and there may be as many as thousands of brands, but there are not many truly trustworthy brands. Industry experts said: 'The quality of products below 30 yuan is difficult to guarantee.
'First, look at the product packaging: see if there is a product trademark, and see if the rated voltage, voltage range, color temperature, precautions, safety instructions, applicable environment, etc. of the product are clearly marked.
Second, price comparison: due to special reasons in the production process of LED lamps, the cost is relatively high. Generally, the price of domestic LED lamps is above 40 or 50 yuan, while that of imported LED lamps is higher.
In addition, look at the appearance of the product is not rough, is there glue is not cleaned, is there a screw protruding fixed plane?
Whether the color of the screw is consistent with the color of the shell, etc.
Three, after the light needs to carefully observe the color change of the light, if in a short period of time, from yellow light to white light, or from white light to white light with blue, such products have to be abandoned, because there are two possibilities for this situation: First, power supply problems; Second: LED light source selection error.
In addition, the color of the lamp must be positive, and the color of the lamp is the same, that is, it does not flash.
After the LED lamp is started, the heat dissipation of the product can be detected by contacting the surface temperature of the product. If the temperature of the product surface continues to rise within one hour instead of being stable for up to 30 minutes, do not select this product, because the product life is shortened due to heat dissipation.
For the study, researchers defined Leimove as strategies to foster some social good, including programs that benefit community engagement, diversity, the environment, human rights and employee relations.
