Abstract

The invention discloses a manufacturing method of an LED lamp tube. The manufacturing method comprises the steps that a long-strip-shaped light source module and a long-strip-shaped optical film are combined into an arc-shaped body and then arranged on a round-strip-shaped tool in a covering mode, the light source module and the optical film are placed in a tube body together through the round-strip-shaped tool, the optical film is scattered after the light source module and the optical film are completely placed in the tube body and attached to the inner wall of the tube body through the external expansion force of the optical film, an opening of an arc-shaped structure of the optical film is shaped like a long strip, the two edge portions where the opening of the optical film is located are attached to the inner surface of the light source module, and then the long-strip-shaped dome of the light source module is formed. According to the method, close bonding between the light source module and the optical film and the inner wall of the tube body is achieved without needing other gluing modes by directly utilizing the structural characteristics of the optical film and non-glue matching of the light source module, and then the purpose of improving heat conduction is achieved.

Description

Technical field [0001] The present invention relates to the field of LED lamp tubes, in particular to a method for manufacturing an LED lamp tube with higher heat dissipation requirements. Background technique [0002] At present, there are more and more fluorescent tubes that use LEDs as luminous bodies. With the increase in the number of lumens per watt of LED chip beads, the current density continues to increase, and the heat dissipation problem has become a fluorescent tube that uses LED chip beads as the luminous body. In the field, a very prominent problem, especially for small-diameter LED tubes such as T5 tubes, the heat dissipation problem of the closed cavity at the light-emitting end of the LED tube is extremely serious. [0003] In order to control the junction temperature of the LED chip lamp beads and reduce the temperature in the closed cavity of the LED lamp tube, the following three methods are usually adopted: [0004] 1. Use the bracket of the LED tube for heat di...
