A lamp group and its insulation protective jacket

Abstract

The invention discloses a lamp group and its insulation protective jacket mounted on the back light module unit, wherein, the lamp group includes a lampshade, a lining, at least two lamp tubes and an insulation protective jacket, the lining is installed in the lampshade, and trepan borings are provided at the side edge of the lining for the electrode ends of the two lamp tubes to insert in the lining, the insulation protective jacket is provided with a main body and at least a binding hole, the main body is made from transparent material, the binding hole perforates the main body, the bindinghole of the insulation protective jacket is in mutual binding to at least one lamp tube, and the main body coats the electrode end of the lamp tube expose the lining. d in the bush outside the extreme power.

Description

technical field [0001] The invention relates to a lamp tube group, in particular to a lamp tube group of a backlight module, and the lamp tube group has an insulating protective cover. Background technique [0002] Liquid crystal displays have become the mainstream of displays in recent years. Liquid crystal displays mainly use a display panel as a display interface, and one of the key components is a backlight module. The liquid crystal display uses a light emitting element in a backlight module, such as a lamp or a cold cathode fluorescent lamp (CCFL), to provide the light source required by the display panel. Most of the CCFL backlight modules currently seen use more than two lamps to meet the high brightness requirements of large-sized LCDs. [0003] In order to ensure the safety of the lamp tube during installation, the manufacturer will set a bushing (lamp bushing) on ​​the two electrode ends of each lamp tube respectively, and use welding means to fix the electrode e...

AI Technical Summary

Problems solved by technology

[0004] At least two lamp tubes of the existing lamp tube group are arranged adjacent to each other and are welded together in the bushing, and in order to avoid affecting the optical properties of the lamp tube, the bushing only partially covers the front end of the lamp tube, resulting in the Part of the electrode terminal is exposed and not covered

However, cold-cathode fluorescent lamps (CCFL) use high voltage from an external power source to start up. If they are used at high altitudes or in environments with low air pressure, due to the reduced air resistance around the lamp group and the current converter (inverter) interaction will cause the electrons at the electrode end of the two lamps to be in an unstable state

Unstable electrons conduct with each other through the exposed electrode terminals, thereby generating an arc phenomenon and breaking down the lamp tube, resulting in a short service life of the lamp tube
