A bonding-free LED lamp tube and an integrated bonding-free fixing method

Abstract

The invention relates to a lamp tube, in particular to a bonding-free LED (light emitting diode) glass lamp tube. The bonding-free LED lamp tube comprises a lamp tube cover, a lamp panel and lamp holders, wherein the lamp panel is arranged in the lamp tube cover; the lamp holders are arranged on two ends of the lamp tube cover; the inner surface of the lamp tube cover is provided with an elastomer or a flexible body; the lamp holders are clamped on the inner surface of the lamp tube cover and form clamping connection with the elastomer or the flexible body. An integral bonding-free fixing method comprises the following steps: arranging the elastomer or the flexible body into the lamp tube cover, causing the outer surface of each lamp holder to be in interference fit with the inner surface of the elastomer or the flexible body in the lamp tube cover, pressing the lamp holders into the lamp tube cover to cause the outer surface of each lamp holder to be clamped and fixed with the inner surface of the elastomer or the flexible body in the lamp tube cover through extrusion and / or friction force. After the technical scheme is adopted, the lamp holders, the lamp tube cover and the lamp tube can be more quickly and efficiently installed and fixed, assembling efficiency is improved, and air pollution by the volatilization of glue and harm on a human body are avoided.

Description

[0001] 【Technical field】 [0002] The invention relates to a lamp tube, in particular to a bonding-free LED glass lamp tube. [0003] 【Background technique】 [0004] As a substitute for fluorescent lamps, LED glass lamp tubes have absolute advantages in terms of insulation, heat conduction, and no deformation compared with LED all-plastic lamp tubes. Therefore, in the prior art, LED lamp tube covers are generally made of glass. The installation with the lamp cover adopts the bonding method to bond the lamp holder and the lamp cover together. This installation method requires a lot of labor and production time, which is not conducive to efficient production, and the glue generally contains volatile poisonous gas. It is harmful to the health of the operating staff. Moreover, the lamp boards arranged in the lamp cover in the prior art are also bonded to the lamp cover by glue, which also has the above-mentioned defects. The boss or groove is used to set the lamp board. Although ...

[0004] As a substitute for fluorescent lamps, LED glass lamp tubes have absolute advantages in terms of insulation, heat conduction, and no deformation compared with LED all-plastic lamp tubes. Therefore, in the prior art, LED lamp tube covers are generally made of glass. The installation with the lamp cover adopts the bonding method to bond the lamp holder and the lamp cover together. This installation method requires a lot of labor and production time, which is not conducive to efficient production, and the glue generally contains volatile poisonous gas. Harmful to the health of the operating staff

Moreover, in the prior art, the lamp board arranged in the lamp cover is also bonded to the lamp cover by glue, which also has the above-mentioned defects. The boss or groove is used to set the lamp board. Although this solution can avoid the defects of the bonding method, it is very complicated to process the lamp cover in this way, and the production cost will increase. Moreover, processing a built-in Lamp housings with bosses or grooves can also take a long time to produce
