Why the LED can not replace filament lamp LED ball steep light

LED filament light glow either appearance or point of view, is better than now LED ball steep light, and appearance and traditional incandescent lamp is very like, this is everybody thought LED lamp filament is the final version of the cause of the LED bulb light. But how many have not been able to promote to the market, which cause analysis is as follows:

1) LED lamp filament is too expensive

LED filament material expensive, its reason is that the next big or modify data standard, could fall by material capital, but now the process yield is still has some problems, is now LED filament capital cannot fall. As for solution, now has the manufacturer for how to drop material capital and process yield research progress, this question belongs to, LED the first encapsulation process, which is now many assembly house policy.

other discusses other factors affect the price of LED lamp filament, artificial cost is too large when assembling, after assembling the whole lamp yield is not high, these are all of price for LED lamp filament can't decline.

2) Quality

now is the biggest hood door LED filament light heat dissipation problem, because the LED shape filament itself, so it is difficult to heat dissipation, thus not only accelerate the filament LED light failure, and affect the service life of the LED filament, so how to progress LED filament heat dissipation ability is an important problem now LED lamp filament.

other LED filament have heat dissipation problem, so many vendors will LED wattage of filament, reduce the heat LED filament light occurs when, but relative brightness has been falling. Because leds filament have heat dissipation problem, so the whole lamp cannot be assembled all the wattage progress, but the market think general ball bubble lamp is to be a main lighting, it will be around 1000 lumens brightness. And now on the market some LED filament lamp brightness is probably around 400 lumens, so now the LED lamp filament only when decorate lighting, not when the main lighting.

3) Now LED lamp filament lamp type

most are in line with the traditional incandescent lamp equipment planning, it does not take into account that the LED heat dissipation characteristics of filament lamp, so I can't do higher wattage LED filament lamp.

and now many traditional incandescent lamp manufacturers do LED lamp filament, they just amend the existing equipment a little traditional incandescent filament can produce LED lamp, completely without considering the nature of the LED lamp filament, so no improvement LED the quality of the filament lamp, however we think this kind of practice LED a filament lamp is a transitional product, just to spend is already obsolete incandescent lamp production equipment.

if the LED lamp filament current defects can be improved, and then made of safety glass, glass shell for filament LED light emitting area is large, less glare, is a very good light source. Evidence now LED the exterior of filament lamps and light-emitting viewpoint, is replace incandescent and LED bulb light now is very good product, is also expected to be LED ball steep light final products.
