Description

A new type of fluorescent tube device

technical field

The utility model relates to a novel fluorescent lamp tube device, which belongs to the technical field of fluorescent lamps.

Background technique

The good heat dissipation mechanism of the LED fluorescent lamp ensures the service life of the product. The unique circuit control design really achieves the purpose of high efficiency and energy saving. The power saving can reach more than 60%. It has super high brightness and high color rendering index. It is the latest indoor lighting product and does not need to use ballasts and starters. No flicker, super long life, the use time is more than 50000 hours. At present, LED fluorescent lamps in the industry are divided into "transparent type" and "uniform mist" in terms of appearance; they are divided into "plug-in type" and "chip type" according to the type of LED light source; the disadvantages of the above-mentioned fluorescent lamps are: a. Use "plug-in type" And "chip type" light source, because there will be color difference between different light sources, after making fluorescent lamps through the cover, you can also feel the color inconsistency; b. Using "plug-in type" and "chip type" light sources, because the light source The carrier board is an FR4 board or an ordinary aluminum substrate, there will be some bottlenecks in its heat conduction, and the service life of the entire fluorescent lamp will be shortened.
