Description

Four-sided backlight module

technical field

The utility model relates to a backlight module, in particular to a four-sided backlight module.

Background technique

Most of the existing backlight modules, especially the lighting modules used in advertising lighting, advertising characters, etc., mostly use neon lights as light sources. However, neon lamps have disadvantages such as short service life and high heat generation. The maintenance period is short and the workload is heavy. Moreover, it is difficult to control the light emission of neon lamps and cannot meet the needs. With the development of LED light sources, LED light sources have gradually replaced neon light sources in backlight modules. However, in the existing LED backlight module, the low-power LED light-emitting diode chip is usually welded on the plastic circuit substrate, so the thermal and electrical conductivity is poor, the brightness is low, and the service life is short.
