On August 21, the Guangdong Provincial Quality Supervision Bureau announced the results of the provincial-level special supervision and inspection of the quality of the LED lighting products. The spot inspection found that 17 batches of products were unqualified, and the unqualified product discovery rate was 73.9%. The problem product involves accidental contact with protective parts of live parts, insulation resistance and dielectric strength after wet treatment, mechanical strength, fault conditions, fire protection and flameproofing.
In fact, the news about the failure of LED lighting products testing has appeared many times in the near future. Previously, the Shanghai Administration for Industry and Commerce conducted quality monitoring on the saleable movable general-purpose lamps in the market. After testing, 13 batches of commodities were unqualified. Among them, well-known brands such as Osram and Opus also appeared on the blacklist.
According to the Shanghai Industrial and Commercial Bureau, this time, the quality of various types of portable general-purpose lamps, such as incandescent lamps and fluorescent lamps, is mainly monitored. The problems of unqualified products are mainly concentrated in four aspects: the insertion loss/harassing voltage is unqualified. The external wiring and internal wiring (external wiring cross-sectional area) are unacceptable, the durability test and the thermal test (durability test) are unacceptable, and the structure (stationary)/structure (clamping force) is unacceptable.
Among them, Osram's "Osram" brand flying egg clip light (model specification: RHN-TW13W-EGGYL/13W) produced by Osram (China) Lighting Co., Ltd. does not meet the standard requirements for the clamping force of the mounting plane. If the indicator fails, the lamp may fall off due to its own weight or slight force pulling. "Transportable lamps" produced by Zhongshan Op Lighting Co., Ltd. (model specification: MT-HYOT-02/11W; date of manufacture or batch number: 2010/12/20), heat-resistant, fire-resistant and scratch resistant (heat-resistant) None of them were qualified. If the project fails, it will easily cause deformation, burning and other dangers, which will invalidate the original anti-electric shock protection performance of the lamp.
Industry insiders said that the incident exposed the lighting companies to be not strict. The lighting industry is outsourcing production in large quantities, and this time multiple batches of products have problems or are related to this.
Foundry is causing trouble?
The problem of multiple batches of products in the lighting industry has been detected, and the phenomenon of highly OEM in this industry has surfaced.
The phenomenon of foundry in the lighting industry is very serious, including many large-scale brand companies are doing a lot of OEM. A lighting industry expert said: "In the case of Philips, the world's largest manufacturer of lighting appliances, its lighting products are basically OEM. In addition, OSRAM and NVC lighting also have foundry. Some big brands such as Philips, Osram When the amount of OEM is close to 90%."
Zhang Shanduan, deputy director of the Institute of Electric Light Sources at Fudan University, said that the foundry itself is not wrong, but the foundry is likely to cause problems in the management of the foundry, and the current industry competition is fierce, the industry's cost is on the rise, fluorescent The prices of powder, copper and tungsten wire have risen, while the economic downturn and industry competition have depressed market prices. At the same time, the compression of industry profits will also cause the company to have a compression cost to relax supervision and make quality problems.
The aforementioned lighting industry experts told reporters that the reason why there are a large number of foundry in the lighting industry exists, mainly because many brands and core patents in the lighting industry are in the hands of foreign investors, foreign capital uses the Chinese market to find a large number of low-cost labor costs, and secondly, Chinese lamps The market is mature, and the related lighting production technology is relatively perfect, which meets the needs of famous brand OEMs.
Insulation: UV-resistant, cross-linkable, halogen-free, flame-retardant compound for core insulation.
Core marking: red, black or natural Sheath: UV-resistant, cross-linkable, halogen-free, flame-retardant compound for the insulation sheath.
Cable colour: black or red
These cables need to meet the sunlight resistance and temperature ratings required by the environment.
Solar cables are manufactured for photovoltaic applications.
Both cable types typically contain XLPE insulation and are resistant to sunlight and/or direct burial.

Solar cables are available for indoor and outdoor use for flexible and fixed installations with high mechanical strength in extreme weather conditions.
The cables are designed to withstand the harsh environmental conditions that occur in any fixed, mobile, rooftop or building integrated PV installation.
Applications
Solar energy is used to generate photovoltaic (PV) power by capturing sunlight. The energy is used for solar heating and, thanks to energy conversion, it can also be used to generate electricity. As a result, the demand for solar cables is also increasing. Solar cables are interconnecting cables used in photovoltaic power generation. Solar cables interconnect the solar panels and other electrical components of the PV system. Solar cables are designed to be UV-resistant and weatherproof.
