Abstract

The invention relates to a backlight module (100). The backlight module (100) comprises at least one light-emitting module (1) and further comprises a light guide plate (2) arranged on a light path and on the downstream part of the light-emitting module (1) and a reflector (3) arranged on one side of the light guide plate (2). Light of the light-emitting module (1) enters the light guide plate (2), and part of the light is emitted out through the light-out side of the light guide plate (2); and the reflector (3) enables another part of light shining to the reflector (3) to be reflected back to the light guide plate (2) and emitted out through the light-out side of the light guide plate (2). In addition, the invention further relates to a backlight module chain (200) composed of at least two backlight modules (100) of the type and a light box comprising at least one backlight module chain (200).

Description

technical field [0001] The invention relates to a backlight module used for a light box. In addition, the present invention also relates to a backlight module chain composed of the above-mentioned type of backlight module and a light box with the backlight module chain. Background technique [0002] For the purpose of publicity, people are accustomed to using light boxes for necessary publicity to attract the attention of the target group. Traditional light boxes usually use fluorescent tubes as the backlight source. With the continuous development of LED technology, people are more and more willing to use LEDs to replace various lighting devices. This is because LED lighting has irreplaceable advantages, such as energy saving, ultra-low power consumption, close to 100% electro-optic power conversion, the same lighting efficiency is more than 80% more energy-saving than traditional light sources, and its life is longer. In view of the above advantages, more and more peopl...
