Recently, the Guangdong Provincial Bureau of Quality Supervision issued the results of a provincial-level special supervision and inspection of self-ballasted LED lamp product quality in Guangdong Province. Sampling results show that in the 23 batches of self-ballasted LED inspections, the test failed 17 batches, the failure rate of up to 73.9%.
The spot checks involved self-ballasted LED lights produced by 21 companies in 7 cities including Guangzhou, Shenzhen, Zhuhai, Foshan, Zhongshan, Huizhou and Dongguan. The unqualified project involves protection from accidental contact with live parts, insulation resistance and dielectric strength after wet processing, mechanical strength, fault condition, color product tolerance, general color rendering index, disturbance voltage, lamp power, heat resistance, mutual Replacement, power factor, initial efficacy/light flux, fire protection and flame protection.
It is noteworthy that “Puglia†lighting production in Puglia, Zhongshan, “Wrigley†produced by Dongguan Anshang Chongguang Technology, “BYD Lighting†produced by BYD Industrial in Huizhou, and Zhongshan Lighting Science and Technology "Nitterson Lighting" four major brands of LED lights are black list. Among them, "Nitterson Lighting" LED high-power bulb light was tested up to ten items failed. According to experts, these unqualified items are prone to deformation, burning, and other hazards, which will invalidate the original protection against electric shock.
The news of unqualified LED lighting products has recently appeared several times. As an inevitable trend of the development of lighting, the state and policies to support the project, why the frequency of LED quality problems?
Investment overheating excess capacity
In 2011, China issued a road map for eliminating incandescent lamps and decided to prohibit the sale and import of incandescent lamps for general lighting of 100 watts or more from October 1, 2012. By October 1, 2016, sales and imports of 15 watts will be banned. Incandescent lamps for general lighting above. This means that incandescent lamps will gradually withdraw from the historical stage, and the LED lighting curtain will be formally opened.
Domestic LED industry, from the sapphire material - GaN epitaxial wafer - chip - encapsulation die - each link of LED lighting, have gathered a large number of investors. For instance, MOCVD, a key equipment for the production of epitaxial wafers in the above areas, has installed 300 imported equipment in 2010. The country is expected to import more than 1,000 units in the next three years, which is 10 times more than in 2008. Large-scale centralized introduction of key MOCVD equipment will likely lead to a major outbreak of low-end chip capacity.
The overheated wave of LED investment has caused quality problems in two aspects:
First of all, if the quantity is too much, the manufacturer's miscellaneous products will cause the products to be mixed. As the saying goes, there are all kinds of birds in the forest. There are many LED market companies scattered, the brand may be as many as thousands, but not really trust the brand. A large number of various types of capital inflows, the quality, capability, experience, and management of the company are all uneven, which leads to a great difference in the quality of the output products.
Secondly, LED lighting has not been able to start the civilian market because of high prices, unstable quality, and cost-effectiveness. The market is not expected to be large. However, the influx of capital has led to overcapacity, triggered frequent price wars, and even once a month quoted the phenomenon. In the domestic market, better LED light bulbs cost 50 to 60 yuan, and even better, 100 yuan. The difference is only 3.5 yuan. How can product quality be guaranteed under such a turbulent price dispute? According to industry experts, "The quality of LED products under 30 yuan is hard to guarantee."
Lack of technical talent
Data show that 70% of LED product failures are caused by the problem of the core component, the driving power supply.
The limited technology affects the quality of the product to a great extent, and the lack of technical personnel in the LED lighting industry must be taken seriously. However, contrary to the booming development in this industry, the current domestic counterpart training has been far from keeping up, and there are many empirical talents in the industry, and there are few technical and academic talents. Most of the colleges and universities do not set up professional corresponding to LED lighting. According to statistics, the LED lighting industry professionals have a gap of 30,000, and this number is still rising at a rapid rate.
At present, apart from foreign countries, the LED lighting talents are basically transferred from the traditional lighting industry. The downstream lighting is a good one. The core technologies involved are not many, and the transformation is relatively easy to go wrong, but the upper and middle reaches are different. Many new technologies require high standards and there is no professional talent. Problems are inevitable.
OEM standards lag
The phenomenon of OEM in the lighting industry is very serious, including many large brand companies have taken a lot of OEM. According to experts in the lighting industry, “For Philips, the world’s largest lighting manufacturer, the lighting products are basically foundry. In addition, OSRAM and NVC lighting are also foundry. Some large brands were close to nine. to make."
Shenzhen Metrology Quality Inspection Institute experts said that the foundry itself is not wrong, but the foundry is likely to lead to problems with the control of the foundry. In general, according to the contract, if the product is not qualified, the order can be cancelled. The brand enterprise can also choose the OEM factory. In other words, the production of foundry factories is completely controllable. The reason for the brand product's problem is not the OEM model, but there is a problem in the brand companies' acceptance of OEM products. If a brand company sends people to be stationed at a foundry for a long time and supervises and inspects the production process of the foundry, problems can be discovered in time and reworked in time. If the product is rejected, it will be rejected. This will basically eliminate the unqualified products in the foundry process. appear.
The healthy development of the LED industry can not be separated from product standards and related technologies, but the rapid development of emerging industry technologies has brought problems such as standard formulation and detection technologies.
Supervision needs to be increased. As the LED lighting products have just been listed in the legal inspection catalog, the transitional period is currently adopted. Therefore, the inspection and supervision of LED lamps and lanterns has yet to be strengthened.
