In the early 2013 s, the LED filament lamp, which was exposed in the early 2014 s, was favored by more enterprises. The scale of production capacity increased rapidly, the technology became more mature, and the price was also declining, the price of filament dropped from 4 yuan/article to 2 yuan/article. It has been predicted that filament lamps will be one of the inevitable hot products. It is understood that the reason why LED filament lamps are popular is mainly that their appearance is similar to that of incandescent lamps, catering to some consumers with nostalgia. In addition, the lighting of LED filament lamps can also show the effect of incandescent lamps in crystal lamps, European lamps and other fields, so there is also a certain demand in this part of the field. However, some people in the industry believe that LED filament lamps have the problems of poor heat dissipation, low power and unstable performance, and LED filament lamps are on the way back. Therefore, for LED filament lamps, on the one hand, it is necessary to ensure the stability of product performance, on the other hand, it is necessary to continue to work hard in terms of cost performance. Only in this way can LED filament lamps get rid of the situation of selling feelings and truly become a mainstream product in the field of LED light sources. There is still a long way to go for the heated discussion of LED filament lamps. It is completely understandable that he Xueli, the general manager of Dongguan's one lamp and one lighting, has won the favor of consumers, LED filament lamps are quite similar in appearance to incandescent lamps used before, catering to the needs of some consumers with nostalgia. In addition, LED filament lamps are quite eye-catching in the field of European lamps and crystal lamps, and may even occupy a part of the market share. However, there is still a long way to go for the immature LED filament. At this stage, the price of LED filament lamps is relatively high, and the quality and technology of products are immature and unstable, which leads to the fact that LED filament lamps often have no obvious advantages when accepting market tests, not fully recognized by the market. However, after the quality of LED filament lamps is gradually maturing and the price is relatively close to the ground, LED filament lamps will give full play to their huge advantages and become one of the products favored by consumers. LED filament lamp to the industry is not only a product or technology, but also a creation and exploration of the unknown. Let the light return to its original appearance, Shi Yan, general manager of Shanghai Grun Laite lighting, with the increase in market demand for LED products, filament LED bulbs also came into being. Filament LED is a breakthrough in technology. It is incomparable to all kinds of LED bulbs in the market at present in terms of structure, material and Performance Index. The filament LED bulb has the characteristics of high luminous flux and 360-degree luminous without dark area, which shows the light thoroughly and simply. The appearance of the light source should be simple, and the property of the light source itself cannot be destroyed when matched with the light lamp; The light color should be pure and can restore the original color of things. The filament LED has these characteristics. At present, the important reason that affects the hot sale of filament LED bulbs is the price. Due to its special structure and process, many processes need to be completed manually, with low efficiency and low qualification rate, making the overall price of the whole product High. In my opinion, filament LED will have great market development space in the future. Although there are still some minor defects in filament LED products at present, with the continuous emergence of new technologies and new materials, filament LED must become of high quality and low price, which is favored by consumers.
