Abstract

A manufacturing method for a light board includes step a, covering a light reflection layer on one surface of a galvanized plate; step b, producing a forming space by applying a stamping process along a direction from the light reflection layer to the galvanized plate; and step c, disposing a plurality of light bead bars on the light reflection layer. Accordingly, as one surface of the galvanized plate is covered by the light reflection layer, the application of the light reflection layer at the inner surface of the board increases the light reflection performance of the board so as to improve the whole lighting effect and the illumination performance of the light board. Moreover, as the outer surface of the board is the galvanized plate, the outer surface of the board has the anti-corrosion effect.

First claim

What is claimed is:

1. A manufacturing method for a light board, comprising:
step a, covering a light reflection layer on one surface of a galvanized plate; step b, producing a forming space by applying a stamping process along a direction from the light reflection layer to the galvanized plate; and step c, disposing a plurality of light bead bars on the light reflection layer;
wherein the galvanized plate after being stamped to comprise a base and a plurality of side plates, the side plates are extending from the base, extending along a direction, and connected to each other, wherein an included angle of each of the side plates and the base is greater than 90° but less than 180°, and the base and the side plates form the forming space.

2. The manufacturing method according to claim 1 , wherein the light reflection layer is made of polyethylene terephthalate.

3. The manufacturing method according to claim 1 , wherein the light reflection layer partially covers the galvanized plate.
