Since January 1 this year, the United States has completely banned all incandescent lamps. This will mean that the penetration rate of LED lighting in the United States will further increase. LED filament lamps, which are known as alternatives to incandescent lamps on the market, have also seen market opportunities. In 2014, LED filament lamps undoubtedly became a hot topic in the industry discussion in various lighting exhibitions and related seminars. With a series of advantages such as 360 lighting, energy saving and environmental protection, and high light efficiency, it has quickly opened the door to Europe and South America and other countries and regions. However, although the manufacturers of LED filament lamps are now in the market, the door to the US market has not yet been able to really knock open. What is it? The US market has not yet fully opened, mainly because the UL certification of LED filament lamps has not yet passed. Yapeng Lighting Chairman Dai Jian accepted an exclusive interview with China LED Network Editor. He said that Yap has passed FCC certification, UL certification and Energy Star certification are also preparing, I believe that the US market will soon be opened. According to Xie Zhenhua, Lighting Product Technical Manager of SGS Consumer Electronics Division, UL certification is not a compulsory certification for LED lamps entering the US market. However, it is a certification that consumers are more recognized. Through this certification, the acceptance of the product is high. An industry insider who asked not to be named told the editor of China LED Network that the power supply inside the LED filament lamp currently on the market mostly adopts the method of resisting and reducing the voltage, which is impossible to pass the US safety certification. Wang Peng, deputy general manager of Baishi Optoelectronics, said that the problems raised by the above-mentioned insiders are the common problems in the small segment of LED filament lamps. Because the LED filaments and the LED filament lamps were separated before, many enterprises that made finished products were turned over by incandescent lamps. They are not very familiar with the power supply, so there are many power sources on the market that are relatively resistant. low. Wang Peng introduced that there are currently three types of power supplies for LED filament lamps: resistance-capacitor buck, switching power supply, and constant current source. If it is for the US market, or some countries and regions with strict requirements, the way to resist the pressure reduction is not acceptable, only the latter two can be used. We use a constant current source. Dai Jian said that the current price war in the market is fierce, Yap has adjusted its strategy and its products have developed to two levels. The high end is doing very well, and the low end will keep the price as low as possible. The power supplies used for LED filament lamps exported to Europe, America, and Japan are all constant current sources. According to Wang Peng, LED filament lamps have to face two major problems when they pass the UL certification in the United States. First, the lamps should be extinguished after the lamps are broken. Second, the glass casing cannot be broken into pieces, and can only be broken into pieces. The human body causes damage. The first problem can be handled on the power supply and we have solved it. The second question is still discussing how incandescent lamps were handled before. Wang Peng told the editor of China LED Network that the UL certification will be the second confirmation of the products of Baishi. As for the glass shell can not be broken into pieces, can only be broken into the shape of the end, Dai Jian said that the Yapuer LED filament lamp through a film on the outside of the lamp, like the car glass, broken The glass will be wrapped in a plastic film. This method does not affect the light transmittance and light efficiency of the LED filament lamp, and there is no visual difference. The UL certification certificate will be available in two months. Dai Jian said. In addition to UL certification, in order to better develop the US market, some companies are also doing related certifications such as Energy Star. The ENERGY STAR website recently revealed that many retailers are prioritizing the promotion of ENERGY STAR LED bulbs because they want to give consumers an excellent lighting experience. As a government-backed certification, the ENERGY STAR label indicates that the bulb has been independently certified and has undergone numerous tests to ensure performance, achieving high brightness and matching the light distribution of conventional bulbs. We have already done the ENERGY STAR for a total of 18 months. We have been doing it for 5 months. This will definitely be a problem. It is only a matter of time. Dai Jian said that after the LED filament lamp passed the Energy Star, enterprises can get the corresponding subsidies, which is very beneficial for opening the US market. Wang Peng told the editor of China LED Network that we are cooperating with two mainstream distributors in the United States. If customers have the certification requirements of ENERGY STAR, they will also do relevant certification. (Text / China LED Network Sophie)
