External heating equipment used for manufacturing LED straight lamp

Abstract

The invention relates to external heating equipment used for manufacturing an LED straight lamp. The external heating equipment comprises an induction coil, the diameter of the induction coil is larger than the outer diameter of a lamp cap of the LED straight lamp, the induction coil generates heat after being powered on, and heat is transmitted to the lamp cap of the LED straight lamp for installation; and a lamp tube and lamp cap connecting method of the LED straight lamp using the external heating equipment is synchronously disclosed.

Description

technical field [0001] The invention relates to the field of lighting appliance manufacturing, in particular to an external heating device for manufacturing LED straight tube lamps. Background technique [0002] LED lighting technology is rapidly developing to replace traditional incandescent and fluorescent lamps. Compared with fluorescent lamps filled with inert gas and mercury, LED straight tube lamps do not need to be filled with mercury. Therefore, in a variety of lighting systems for home or workplace dominated by lighting options such as traditional fluorescent bulbs and tubes, LED straight tube lamps have gradually become a highly anticipated lighting option. The advantages of LED straight tube lights include increased durability and lifespan as well as lower energy consumption. Therefore, after all factors are considered, LED straight tube lights will be a cost-effective lighting option. [0003] Known LED straight tube lamps generally include a lamp tube, a circ...

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
