Built-in power type safe LED fluorescent tube lamp holder

Abstract

The invention relates to a built-in power type safe LED fluorescent tube lamp holder which is characterized by being provided with a circular shell, wherein the shell is divided into a front part and a back part by a partition; the front part is a closed cavity, and the rear part is an open structure which is combined with the tube lamp body; the front end face of the closed cavity is provided with a pair of lamp holder contact pins, and middle part of the cavity is provided with a position sensor unit which forms a loose fit with the inner diameter of the shell; the position sensor unit is made of an insulating material; a position sensing ball, which is exposed outside the front end face and has the function of retraction, is arranged between the position sensor unit and the front end face; a pressure spring is arranged between the position sensor unit and the partition; the position sensor unit and the partition are respectively provided with an electricity applying contact and an electricity receiving contact matched with the electricity applying contact; and the lamp holder contact pins are electrically connected with the electricity applying contact. The invention is convenient to use and greatly enhances the electricity use safety.

Description

technical field [0001] The invention relates to a lamp, in particular to a safety lamp holder of an LED fluorescent lamp tube. Background technique [0002] The wiring method of built-in power supply type LED fluorescent tubes is strictly restricted by safety certification. Since the driving power of the LED fluorescent tube is built-in, the power supply cannot be supplied from both ends of the fluorescent tube like a fluorescent fluorescent tube. The method is used for the subsequent stage circuit. Then, when one end of the built-in LED fluorescent tube is in contact with the electrode of the lamp holder, the other end of the lamp tube will carry the AC voltage of the power supply grid, and the human body will get an electric shock when it touches it. This is in UL And other safety certification is strictly limited, for this reason, the usual processing method is to adopt a different wiring method from the fluorescent fluorescent tube, that is, only one end of the LED flu...

AI Technical Summary

Problems solved by technology

[0003] 1. Potential safety hazards of power supply at one end

[0004] LED fluorescent tubes are powered by one end, and there may be a short circuit due to the short distance between the two pins at one end

[0005] 2. The lamp installation is inconvenient

[0006] Since one end supplies power and the other end does not, when installing the lamp tube, there will be a 50% chance that the lamp tube will not be powered on. At this time, the lamp tube needs to be removed, and the lamp tube should be rotated 180 degrees horizontally to reinstall, which increases the Time and Difficulty of Installation

[0007] 3. Different from the power supply method of traditional fluorescent fluorescent tubes, it is easy for people to make mistakes when performing line transformation
