An external heating device for manufacturing led straight tube lamps

Abstract

An external heating device for manufacturing LED straight tube lamps, comprising an induction coil, the diameter of the induction coil is larger than the outer diameter of the lamp cap of the LED straight tube lamp, the induction coil generates heat after being energized, and conducts the heat to the lamp cap of the LED straight tube lamp Installing; simultaneously disclosing a lamp tube and lamp base connection method of an LED straight tube lamp using external heating equipment.

Description

Technical field [0001] The present invention relates to the field of lighting instruments, and more particularly to an external heating apparatus for manufacturing an LED straight tube lamp. Background technique [0002] LED lighting technology has developed rapidly and replaced traditional incandescent lamps and fluorescent lamps. The LED direct tube lamp does not need to be filled with mercury compared to filling the fluorescent lamp with inert gas and mercury. Therefore, in various illumination systems used by a household or workplace dominated by a traditional fluorescent bulb and a lamp and tube, the LED direct tube light is not intended to become a highly expected lighting option. The advantages of the LED direct tube lamp include increased durability and life, and low energy consumption. Therefore, after considering all factors, the LED direct tube light will be a cost-saving lighting option. [0003] LED direct tube lamps typically include a lamp, a circuit board provided...

AI Technical Summary

Problems solved by technology

[0004] In existing LED straight tube lamps, white glue is usually used for bonding between the lamp cap and the lamp tube. As mentioned in the CN102052652A patent publication, epoxy resin glue is used to seal the LED lamp cap, and the publication number is The Chinese patent application of CN102777788A discloses an LED fluorescent lamp, which includes a lamp body and plugs installed at both ends of the lamp body for connecting to a power supply. There is a groove corresponding to the magnetic block, and the surface of the groove is iron sheet, so as to achieve the effect of magnetic connection; however, the traditional white glue has poor adhesion and durability, and the effect of magnetic connection is limited. It is not as good as through Viscous medium achieves the connection effect

In addition, when the lamp tube is directly connected to the lamp holder, it is difficult to control the overflow of the glue. If the excess glue is not removed, it will affect the appearance and cause shading problems; if you want to remove the excess glue, you need to use a lot of manual wiping in the manufacturing process, causing production obstacles and low efficiency

In addition, the poor heat dissipation of the power supply components in the lamp cap will easily lead to a high temperature environment in the lamp cap, thereby reducing the service life of the hot melt adhesive and reducing the adhesion between the lamp tube and the lamp cap, resulting in a decrease in the reliability of the LED straight tube lamp
