LED filament lamp either appearance or light angle, than current LED bulb is good, but looks like a traditional incandescent lamp, this is also the reason that the LED is the final version of the filament lamp LED bulb. But why we have not been able to implement a lot of the market, for reasons as follows:

1) Price LED filament lamp too expensive

  The reason is because your LED filament material, after large or modify the material specification, may reduce material costs, but the current process yield still have some problems, is unable to reduce the cost of LED filament reasons. As for solutions, there are vendors on how to reduce material costs and increase process yield research, this problem belongs to the preceding LED packaging process, which is currently a lot of packaging factory goal.

   Also explore other factors that affect the price of LED filament lamp, labor cost too much when assembling after assembling the entire light yield is not high, they are making the price LED lamp filament reasons can not be reduced.

2) Quality

  Currently LED lamp filament biggest Achilles Heel is the heat problem, because LED filament shape problem itself, it is more difficult to heat, so that not only accelerate the LED filament light failure, but also affect the LED life of the filament, so to how to improve the cooling capacity LED filament is Currently important issues LED filament lamp.

   Also LED filament has heat problems, so many manufacturers to reduce the wattage filament of LED, reduce the heat generated when the LED is lit filament, but the relative brightness is reduced. Because LED filament has heat problem, so the whole lamp wattage whole assembly can not be improved, but that the market in general to be the main bulb lighting, brightness probably about 1,000 lumens. And currently on the market of LED filament lamp brightness in about 400 lumens, so the current LED filament lamp can only be decorative lighting, can not when the main lighting.

3) Current LED lamp filament lamp type

   Most are for the device with the traditional incandescent lamp design, there is no consideration of the filament lamp LED heat dissipation characteristics, we can not do high wattage LED filament lamp.

  And now many traditional incandescent filament manufacturers switch to LED lights, they just existing equipment slightly modify the traditional incandescent LED filament lamp can be produced, without considering the characteristics of LED filament lamp itself, it can not improve LED filament lamp quality, but we believe that such practices LED filament lamp is a transitional product, only to consumption has to be scrapped incandescent production equipment.

   If you can LED lamp filament current shortcomings to be improved, and then the glass enclosure made of safety glass, due to large LED filament light emitting area, relatively no glare and other issues, is a good light source. According to the current LED lamp filament shape and hair
