A light tube that is easy to install

Abstract

The invention relates to a convenient-to-install lamp tube, which comprises a lamp shade, a heat radiation lamp case, an LED (light emitting diode) luminous assembly, an LED driving circuit, a first end cover and a second end cover, wherein the first end cover and the second end cover are respectively provided with a pair of lamp pins, each of the first end cover and the second end cover comprises a fixed cover and a rotating cover, the fixed cover is connected with the lamp tube, the rotating cover is provided with the lamp pins, is inserted, matched and connected onto the fixed cover and can rotate relative to the fixed cover, an annular part provided with a position limiting groove at the inner circumference wall is arranged on the outer end surface of the fixing cover, a positioning element connected with the rotating cover is rotationally arranged in the annular part, and at least one convex tooth matched with the position limiting groove is arranged on the outer peripheral surface of the positioning element. The convenient-to-install lamp tube has the advantages that the fixed cover and the rotating cover are in inserted and matched connection, the installation is convenient, a user can rotate the rotating cover according to requirements, the positioning element connected with the rotating cover can rotate along with the rotating cover, in addition, the convex teeth arranged on the outer peripheral surface of the positioning element is clamped into the position limiting groove, and the corresponding angle can be limited, so that the regulation on the illumination angle of the lamp tube is realized, the operation is fast, and the use is convenient.

Description

technical field [0001] The invention relates to a lamp tube, in particular to a lamp tube of an LED fluorescent lamp which is easy to install. Background technique [0002] LED fluorescent lamps are gradually replacing ordinary fluorescent lamps due to their advantages of small size, energy saving, environmental protection, long service life, and low noise. The lamp tube of the existing LED fluorescent lamp includes a lampshade, a heat dissipation lamp housing, an LED lighting assembly, and a first end cap and a second end cap respectively with a pair of pins, wherein the first and second end caps are respectively fixed on the lampshade and the heat dissipation lamp. At the two ends after the shells are connected, the LED light-emitting components and the LED drive circuit capable of driving the LED luminous body are all located in the space formed by the lampshade and the heat-radiating lamp shell. [0003] In the lamp tube of an earlier designed LED fluorescent lamp, the ...

AI Technical Summary

Problems solved by technology

[0003] The lamp tube of the LED fluorescent lamp designed earlier, the end caps at both ends are fixedly connected with the radiator lamp housing through screws, once the installation is completed, the lampshade, radiator lamp housing and LED luminous body cannot be rotated and adjusted as required

The LED illuminant in the LED fluorescent lamp adopts a patch-type lamp bead, and its light has a certain direction. Therefore, the use of the traditional end cover will cause the LED fluorescent lamp to have a blind area of ​​irradiation.

And the distribution positions of the pin holes in the current installation occasions are also different, so the structure of the fixed connection between the end cover and the lamp housing is not easy to install.
