Problems solved by technology

[0005] 1. The cost of preparing molds such as male molds and female molds is relatively high, which in turn makes products made of the light-emitting diodes, such as lighting modules, have a high unit price
[0006] 2. The product cannot be thinned. If the product needs to be thinned, the precision of the male mold and the female mold must be improved, and the strength of the mold is not good, which will shorten the service life of the mold
[0007] Another manufacturing method of the reflective component is formed by metal rolling. It first prepares a rolling wheel with a pattern on the surface, and rolls the rolling wheel on an aluminum or white iron sheet to form a metal sheet with a pattern. Reflective components with inclined reflective walls; however, this manufacturing method also has the disadvantage of not being able to produce precision or miniaturization

Abstract

The invention relates to a method for shaping a reflection wall of a light-emitting diode module, which comprises the steps of attaching a substrate on a shaping mold for shaping the wall surface by the vacuum pumping shaping way, and further forming a reflection film on the wall surface for completing a finished product of the reflection wall. The reflection wall can reflect a light-emitting diode light source for changing the light path, thereby upgrading the brightness representation of the light-emitting diode; furthermore, the structure of the reflection wall with great precision and narrow-spacing arrangement can be formed by the shaping method of the invention, thereby simplifying the processing steps and reducing the development cost.

Description

technical field [0001] The invention relates to a method for forming reflective walls of LED modules, and aims to provide a method for forming more precise and narrow-pitch reflective wall structures, which can simplify processing steps and reduce development costs. Background technique [0002] Press, traditionally in the era of undeveloped technology, a simple monochromatic bulb is used as the light source of the lamp. If you want to achieve color changes, you need to match a colored lampshade that can pass through the light to make the light emitted by the bulb After the lampshade is exposed, different colors can be formed. However, the disadvantages of this lamp structure are slow response, power consumption, heat generation and short life. Moreover, after the bulb is broken, it will no longer provide lighting functions. Moreover, the light emitted by the bulb must pass through the lampshade, so that the brightness of the light will decrease. [0003] Therefore, in rece...
