Telescopic wide-angle LED light-emitting tube

Abstract

The invention discloses a telescopic wide-angle LED light-emitting tube. The light-emitting tube comprises a protection box, a positive binding post is arranged in the position, close to the lower end, of one side of the protection box, a negative binding post is arranged in the position, close to the lower end, of the other side of the protection box, an adjusting groove is formed in the front surface penetrating through the protection box, a tooth groove is formed in the position, located on one side of the adjusting groove, of the front surface penetrating through the protection box, a limiting hole is formed in the center of the top end of the protection box in a penetrating mode, a lamp bead is arranged in the position, corresponding to the limiting hole, of the upper end of the protection box, a lower conducting strip is mounted at the bottom end in the protection box, an adjusting mechanism is arranged in the position, close to the edge, of the lower end of the lamp bead, a connecting mechanism is arranged in the center of the lower end of the lamp bead, a lead is mounted at the lower end of the connecting mechanism, the size of an adjusting button is matched with that of the tooth groove, and the adjusting button is arranged in a shifting manner. The illumination range of the lamp bead can be conveniently adjusted under the condition that the voltage and the brightness of the lamp bead are not changed, meanwhile, when the LED light-emitting tube is not used, the lamp bead is protected, and the lamp bead is convenient and rapid to mount and dismount.

Description

technical field [0001] The invention relates to the field of LED light-emitting tubes, in particular to a telescopic wide-angle LED light-emitting tube. Background technique [0002] LED light-emitting tube is a new type of cold light source, which has high energy efficiency, long life, low voltage, simple structure, small size, and light weight. LED light-emitting tubes are divided into many types, and the end of the wide-angle LED light-emitting tube is hemispherical. , which is more conducive to the divergence of the light source. [0003] The existing wide-angle LED light-emitting tube has certain disadvantages in use. The existing wide-angle LED light-emitting tube cannot protect the lamp bead when it is not working; The brightness of the lamp bead is determined. When adjusting the light range, the brightness of the lamp bead can only be changed by adjusting the voltage. It is impossible to adjust the light range while maintaining the brightness of the lamp bead. Disa...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a telescopic wide-angle LED light-emitting tube, which solves the problem that the existing wide-angle LED light-emitting tube cannot protect the lamp bead when it is not working; The range is determined by the brightness of the lamp bead. When adjusting the light range, the brightness of the lamp bead can only be changed by adjusting the voltage. It is impossible to adjust the light range while maintaining the brightness of the lamp bead; Installation and disassembly need to be realized with the help of electric soldering pen and solder paste, which is a troublesome problem
