The heat resistance is not enough. It may be that in order to reduce the cost, the company uses plastic parts that are not up to standard, and the flame retardancy does not meet the requirements, which poses a safety hazard. The safety of home appliances has always been valued by consumers. It is not enough to use LED bulb lighting only for brightness and energy saving. If the safety indicator is not enough, the light will be bad, and the light may cause fire. In January 2015, Consumer Reports purchased Philips, Op, Mulinsen (41.43, 0.45, 1.10), Langshi Lighting, Foshan Lighting (14.58, 0.00, 0.00), Sanxiong Aurora, Benbang International Lighting, etc. The brand indoor LED bulb lamp samples are sent to a third-party testing agency for comparison of heat resistance testing. The test results show that among the 7 brand LED bulbs, the heat resistance of Langshi Lighting's inspection samples does not meet the national mandatory standards. This is also the LED lighting company with the most problems among the 7 brands tested this time. Heat resistance, but the fire hazard of fire hazard is not enough. It may be that in order to reduce the cost, the company uses plastic parts that are not up to standard, and the flame retardancy does not meet the requirements, which poses a safety hazard. The safety of the product is of the utmost importance to the consumer, so do not use the product that does not meet the heat resistance. LED bulbs are safe for the first time before energy and comfort are considered. Zhang Shanduan from the Institute of Electric Light Sources of Fudan University told the Consumer Reporter. According to the national mandatory standard GB24906-2010 "Safety requirements for self-ballasted LED lamps above 50V for general lighting", the heat resistance test is carried out, and the ball pressure test is required to judge. The standard indicates that the lamp should have sufficient heat resistance and provide protection. The insulating material for electric shock protection and the insulating material member for fixing the live parts should have sufficient heat resistance. If it is embodied in the experiment, it is a ball pressure test; that is, the plastic insulation material of the lamp cap is first heated to a temperature of 125 degrees, and then the steel ball with a diameter of 5 mm is pressed against the insulating material for 20 hours with a force of 20 n. Whether the crack is more than 2 mm as specified by the standard. The test results show that Philips' crack is 1.4 mm, Sanxiong Aurora 1 mm, Opal 1.1 mm, Mulinsen 1.4 mm, Foshan Lighting 0.9 mm, and Benbang International Lighting 0.8 mm. Langshi Lighting's ball fracturing reaches 2.6 mm, exceeding the national mandatory standard for heat resistance of 2 mm. Philips Lighting replied that this product indicates that the heat resistance index is not enough, the general service life cannot reach the claimed value, and there are safety hazards. The general cause of failure to heat is excessive product cost reduction, the use of fewer LED particles, and components with poor parameter performance, and the irrational design of the product system is also an important reason. As of press time, the magazine has not received any response from Langshi Lighting. The heat resistance is most important because the lamp insulation of the bulb has sufficient heat resistance. The heat resistance of the insulating material of the lamp cap is not enough, which may cause the lamp cap to be separated from the lamp body, which may cause harm to the user; it may also cause a short circuit of the circuit. If a protective switch is installed in the house, the short circuit may trip, but if no protective device is installed, If the switch is broken or the gate is broken, a large current will cause a fire. Lin Shujian, engineer of the technical department of China Saibao Quality Inspection Center, told this reporter. Industry supervision needs to be improved as the leading level in the domestic LED industry in Guangdong, with the industry being concentrated in Zhongshan and Foshan and Dongguan. As a well-known LED brand in the province, Langshi Lighting is still a nationally compulsory standard for heat resistance. In fact, Langshi Lighting has a previous record in the previous supervision and spot checks. In January 2014, the State Administration of Quality Supervision, Inspection and Quarantine announced the results of the national supervision of LED product quality, a total of 108 batches of LED lighting products produced by 82 enterprises nationwide, including LED downlights and self-ballasted LED lights for general lighting. . The spot check found that 22 batches of products produced by 21 companies did not meet the standard requirements. Among them, the problem products include a ROSY Langshi self-ballasted LED lamp produced by Foshan Langshi Lighting Co., Ltd. In April 2014, in the sampling inspection of LED bulbs by Guangzhou Industrial and Commercial Bureau, 50 products were also unqualified. On the other hand, at that time, some enterprises believed that the industrial and commercial sampling inspection did not conduct random inspections on the core indicators such as light efficiency, color rendering index and brightness of LED lamps, and only stayed on the sampling inspection of signs and energy efficiency labels. Only by issuing relevant standards as soon as possible and strengthening the detection of the core performance indicators of LED lamps can we truly play a role in regulating the market.
