1. Small size, heat dissipation and light decay are big problems
Lightman believes that to improve the filament structure of LED filament lamps, LED filament lamps are currently filled with inert gas for radiation heat dissipation, and there is a big gap between the actual application and the design effect. Also, since the LED filament is a chip in the form of a COB package, the use of some effective technical means to reduce heat generation or rapid thermal conduction is a guarantee of low light decay and long life of the LED filament lamp, such as optimization of the substrate shape and substrate material. Selection, thermoelectric shunt mode, etc.

2. Can’t completely eliminate stroboscopic
Regarding the problem of stroboscopic flashing of LED filament lamps, lightman believes that LED filament lamps are small in size and small in installation space. The limited installation space has very strict requirements on the volume of components, and currently can be used with low power and small installation space. Only high pressure linearity of the product meets this requirement. Due to the “hole” effect caused by high-voltage linearity in the rapid passage of current, it is very difficult to achieve stroboscopic flash in large-scale production capacity under the premise that the compensation technology lacks fine technical means. There is absolutely no stroboscopic and there is no absolute solution. Only the technical means can be used to reduce the “hole” effect and control the stroboscopic to a certain ext
