(1) The price of LED filament lamp is too expensive The reason is because the material of the LED filament is expensive, and the amount of material is large or the material specification may be modified, which may reduce the material cost. However, the current process yield still has some problems, which is the reason why the current cost of the LED filament cannot be reduced. As for the solution method, there are already manufacturers research on how to reduce the material cost and improve the process yield. This problem belongs to the LED front-end packaging process, which is also the goal of many packaging factories. In addition, the other price factors affecting the LED filament lamp are discussed. The labor cost during assembly is too large, and the whole lamp yield is not high after assembly. These are the reasons why the price of the LED filament lamp cannot be lowered. (2)) Quality At present, the largest cover door of LED filament lamp is a heat dissipation problem. Because the shape of the LED filament itself is difficult, heat dissipation is difficult, so it not only accelerates the light decay of the LED filament, but also affects the life of the LED filament. Therefore, how to improve the heat dissipation capability of the LED filament is At present, the important problem of LED filament lamps. In addition, LED filaments have heat dissipation problems, so many manufacturers reduce the wattage of LED filaments, reducing the heat generated when the LED filaments are lit, but the relative brightness is also reduced. Because the LED filament has heat dissipation problems, the whole lamp assembly cannot improve the overall wattage, but the market believes that the general bulb should be the main illumination, and the brightness is about 1000 lumens. At present, the brightness of LED filament lamps on the market is about 400 lumens, so the current LED filament lamps can only be used as decorative lighting, and cannot be used as the main illumination. (3)) The current type of LED filament lamp Most of them are designed to match the traditional incandescent lamp equipment. They do not consider the heat dissipation characteristics of the LED filament lamp, so it is impossible to make a relatively high wattage LED filament lamp. Moreover, many manufacturers of traditional incandescent lamps have turned to LED filament lamps. They can produce LED filament lamps with a slight modification of existing traditional incandescent lamps. They do not consider the characteristics of LED filament lamps themselves, so they cannot improve LED filament lamps. The quality, however, we believe that the LED filament lamp of this kind is a transitional product, just to consume the incandescent lamp production equipment that has been scrapped. If the current shortcomings of the LED filament lamp can be improved, and the glass casing is made into a safety glass, the LED filament has a large luminous area and is relatively glare-free, and is a good source of illumination. According to the current appearance and illumination angle of the LED filament lamp, it is a good product to replace the incandescent lamp and the current LED bulb, and it is also expected to be the finalized product of the LED bulb.

Why is the current LED filament lamp not a replacement for LED bulbs?
LED filament lamps are better than current LED bulbs in terms of appearance and illumination angle, and their appearance is similar to that of traditional incandescent lamps. This is why LED filament lamps are the final version of LED bulbs. However, why has it not been able to implement it in the market in a large amount, and the reasons are as follows:
