改善LED灯丝灯光斑效果的途径

Solution of Improving Facula Effect in LED Filament Lamp

随着LED灯条技术工艺的成熟,外形酷似白炽灯的LED灯丝灯越来越受市场青睐。LED灯丝灯的发光器件由线状的灯条构成,内芯结构多似伞状,这种结构形式的弊端就是发光效果不均匀,"灯下黑"是最为显著的缺点,因此光斑问题是制约灯丝灯发展的技术瓶颈,文章简述1种改善灯丝灯发光效果的工艺方法。

With the mature of LED filament technology,the LED filament lamp,which has the similar shape of incandescent light bulb,becomes more and more popular in the market.The light-emitting device of LED filament bulb is the linear filament,of which the structure is mostly umbrella like.The malpractice of this structure is that the light effect is not uniform,and the parts below the lamp are black is the major defect.Therefore,lamp facula is the bottleneck of the filament lamp＇s developing.This article narrate the way of improving filament lamp facula effect.
