LED lamp tube and manufacturing method thereof

Abstract

The invention discloses an LED lamp tube and a manufacturing method of the LED lamp tube. The LED lamp tube comprises a lamp tube body, an LED light source assembly arranged in the lamp tube body, and a lamp pin set arranged on the lamp tube body and connected with the LED light source assembly. The lamp tube body is integrally formed by glass material, and a diffusion coating is arranged on the inner wall of the lamp tube body. Because glass has the characteristic of good luminous flux, the utilization rate of a light source is greatly improved. Because the diffusion coating is arranged on the inner wall of the lamp tube body and diffusion powder is prepared from silicon dioxide micro-powder, nanoscale titanium dioxide and the like and used for divergency of light emitted by an LED chip, light emitted by the LED lamp tube is soft and will not dazzle people, and the lighting effect of the LED lamp tube is further improved.

Description

technical field [0001] The invention relates to an LED lamp, in particular to an LED lamp tube and a manufacturing method thereof. Background technique [0002] Due to its small size, low power consumption, long service life, high brightness, low heat, environmental protection and other advantages, LED has been gradually popularized in daily life. The installation size of the LED light tube is the same as that of the traditional light tube, and it can be used without much modification, and it is energy-saving and environmentally friendly. Therefore, many places now use LED light tubes, and the body of this LED light tube is usually made of Composed of semicircular aluminum profile and semicircular lampshade, the material of the lampshade is mostly made of plastic materials such as PVC, the manufacturing cost of the lamp tube is relatively high, and the assembly is very troublesome. Moreover, the lamp tubes made of plastic materials such as PVC, due to the influence of the m...

Problems solved by technology

[0002] Due to its small size, low power consumption, long service life, high brightness, low heat, environmental protection and other advantages, LED has been gradually popularized in daily life. The installation size of the LED light tube is the same as that of the traditional light tube, and it can be used without much modification, and it is energy-saving and environmentally friendly. Therefore, many places now use LED light tubes, and the body of this LED light tube is usually made of Composed of semicircular aluminum profile and semicircular lampshade, the material of the lampshade is mostly made of plastic materials such as PVC, the manufacturing cost of the lamp tube is relatively high, and the assembly is very troublesome

Moreover, the lamp tube made of plastic materials such as PVC, due to the influence of the material of the plastic itself, has a low luminous flux rate and poor light efficiency, which reduces the utilization rate of the light source, thereby seriously affecting its lighting effect and wasting energy.
