LED filament lamp can not replace LED bulb

　　LED filament lamp either appearance or light angle, than the current LED bulb is good, and looks like a traditional incandescent lamp, which is we believe that LED lights are the reasons for the final version of the filament LED bulb. But why have not been able to implement a lot on the market, one of the reasons as follows:

　　The reason is because the LED filament material expensive, after a large amount of material specification or modification may reduce material costs, but the current process yield or has some problems, is unable to reduce the cost of LED filament reasons. As for solutions, there are already vendors on how to reduce material costs and improve process yield research, this issue is part of LED front-end packaging process, which is currently a lot of packaging factory goal.

　　Also explore other factors that affect the price of LED filament lamps, artificial spending too much during assembly, after assembling the entire light yield is not high, which makes the price of LED filament lamps are not reasons for the decrease.

　　Another LED filament has heat problem, many manufacturers to reduce the wattage LED filament to reduce the heat generated by the filament when the LED is lit, the relative luminance is decreased. Because the LED filament has heat problems, so the entire lamp assembly can not improve the overall wattage, but think the market in general to become the main bulb lighting, brightness, probably around 1000 lumens. And currently on the market and some LED filament lamp brightness in about 400 lumens, so the current only when the filament lamp LED decorative lighting, you can not when the main lighting.

　　Also present, many manufacturers have switched over to the traditional incandescent filament LED lights, they are as long as the existing traditional incandescent equipment can slightly modify the production of LED filament lamp, without considering the characteristics of the LED filament lamp itself, it can not be improved LED filament lamp the quality, however, we believe that such practices LED filament lamp is a transitional product, just for consumption has to be scrapped incandescent production equipment.
