The spot check involved self-ballasted LED lights produced by 21 companies in 7 cities including Guangzhou, Shenzhen, Zhuhai, Foshan, Zhongshan, Huizhou and Dongguan. Unqualified items involve accidental contact with live parts, insulation resistance and dielectric strength after wet treatment, mechanical strength, fault condition, chromaticity tolerance, general color rendering index, disturbance voltage, lamp power, heat resistance, mutual Transmutability, power factor, initial efficacy / luminous flux, fire and fire protection.
It is worth noting that "Puglia" produced by Pulia Lighting in Zhongshan City, "Wrigley" produced by Dongguan Anshang Chongguang Technology, "BYD Lighting" produced by Huizhou BYD Industry, and Nateson Lighting Technology produced by Zhongshan City "Nexen Lighting" four major brands of LED lights are on the black list. Among them, "Nexen Lighting" LED high-power bulbs were inspected up to ten items and failed. According to experts, these unqualified items are prone to deformation, burning and other hazards, which invalidate the original anti-electric shock protection performance of the lamps.
The news about the failure of LED lighting products testing has appeared many times in the near future. As an inevitable trend in the development of lighting, why do the LEDs and quality policies support the project?
Investment overheated overcapacity
In 2011, China released the roadmap for eliminating incandescent lamps and decided to ban the sale and import of incandescent lamps for general lighting of 100 watts and above from October 1, 2012; by October 1, 2016, it is forbidden to sell and import 15 watts and The above general lighting uses incandescent lamps. This means that incandescent lamps will gradually withdraw from the historical stage, and the LED lighting curtain will be officially opened.
The domestic LED industry, from sapphire materials - GaN epitaxial wafers - chips - packaged die - each link of LED lighting fixtures, has gathered a large number of investors. Take the MOCVD of the upstream epitaxial wafer production as an example. In 2010, 300 sets of imported equipment were installed in the factory. In the next three years, the country is expected to import more than 1,000 units, which is more than 10 times that of 2008. The large-scale introduction of key equipment for MOCVD is likely to lead to a burst of low-end chip capacity.
The wave of overheating LED investment has caused quality problems in two aspects:
First of all, the amount is mixed, and the confounding of the manufacturers has caused the product to be mixed to some extent. As the saying goes, there are many birds in the forest. At present, there are many LED market companies, and there may be thousands of brands, but there are not many brands that are truly trustworthy. A large number of various types of capital influx, the quality, ability, experience, management and other aspects of the enterprise are uneven, which leads to a great difference in the quality of the exported products.
Secondly, LED lighting has not been able to start the civilian market because of its high price, unstable quality, and improved price/performance ratio. The market has not expected much. However, the influx of capital has led to overcapacity, triggering frequent price wars, and even a one-month quotation has occurred from time to time. In the domestic market, a better LED bulb 50~60 yuan, a better 100 yuan, the difference is only 3.5 yuan. Under such a chaotic price dispute, how can product quality be guaranteed? Some industry experts said: "The quality of LED products below 30 yuan is difficult to guarantee."
The LED industry needs to develop healthily and cannot be separated from product standards and related technologies. However, the rapid development of emerging industry technologies has brought difficulties in standard formulation and testing technologies.
The supervision needs to be increased. Since LED lighting products have just been included in the legal inspection catalogue, the transition period policy is currently adopted, so the inspection and supervision of LED lamps needs to be strengthened.
