Lamp box module

Abstract

The invention discloses a lamp box module, which can accommodate at least one long cylindrical light source. The lamp box module comprises a base, at least one light source fixing frame, a light guide plate, a first transparent plate and a front cover. The front cover is combined with the base to form a space for accommodating the long cylindrical light source, the light source fixing frame, the light guide plate and the first transparent plate. The light source fixing frame comprises a light source accommodating part and a wire chase, and the light source fixing frame is arranged around the base and positions the light guide plate into the base. The light source accommodating part accommodates the light source and reflects light rays emitted by the light source to the light guide plate, and the wire chase accommodates a circuit connected with the light source. The waterproof bar is included between the around of the base and the light source fixing frame, and one part of the light source fixing frame is embed in the waterproof bar. The first transparent plate is arranged between the front cover and the light guide plate.

Description

Technical field [0001] The invention relates to a light box module, in particular to a light box module for advertisements or billboards and a manufacturing method thereof. Background technique [0002] In order to effectively attract the attention of passers-by or customers, some advertising light box modules or advertising light boards are often installed in outdoor or public buildings. This kind of light box module or advertising light board is to place a color advertising transparent sheet in front of a light emitting device. The light generated by the light emitting device will penetrate the color advertising transparent sheet and be emitted, so that the pattern or text on the color advertising transparent sheet is clear Visible, so as to attract passersby or customers to pay attention to the content on it. [0003] Since the junction between the light-emitting device and the power supply line connected to the light box module is not protected or fixed well, the problem of fa...

AI Technical Summary

Problems solved by technology

Because the cold cathode lamp needs a rectifier (converter) to supply the AC current of appropriate specifications, it causes many inconveniences in the use of the light box, for example: a space needs to be designed in the light box for a certain volume of rectifier; Moisture protection, otherwise it is easy to cause leakage or circuit damage

[0006] In addition, the color advertising light-transmitting sheets in the light box module or advertising light board need to be replaced frequently. Since the light guide plate is not well isolated and positioned poorly, it is easy to be touched and moved, thus affecting the light-emitting surface. Uniformity of light throughout

On the other hand, in order to satisfy the waterproof tightness of the light box module, the ease of disassembly for replacing the color advertising light-transmitting sheet is often sacrificed.

That is to say, many screws will be loosened every time the color advertising light-transmitting sheet or advertising page is replaced, so it takes a lot of time to complete the replacement action
