Embodiment Construction

[0026] refer to Figure 1-3 , figure 1 The front view of the LED tube lamp provided by the embodiment of the present invention; figure 2 for figure 1 Left side view of the LED tube light shown; image 3 for along figure 1 Sectional view of line A-A.

[0027] Such as Figure 1-3 As shown, the LED tube lamp provided in this embodiment includes a radiator 1 , a light source assembly 2 , a lampshade 3 and a lamp base 4 .

[0028] The radiator 1 has a semi-cylindrical structure, and the radiator 1 can be made of materials with high thermal conductivity, such as aluminum, copper and other materials. The light source assembly 2 is installed on the outer plane 12 of the heat sink 1. The light source assembly 2 can be installed on the outer plane of the heat sink 1 by screws, or the light source assembly 2 and the heat sink 1 can be installed together by bonding or other methods. , The light source assembly 2 may use an LED light source.

[0029] The lampshade 3 is in the shap...

Abstract

The invention provides a light emitting diode (LED) tubular lamp, which comprises a radiator, a light source component, a lampshade and lamp caps, wherein the radiator is in a semi-cylindrical structure; the light source component is mounted on an outer flat surface of the radiator; the lampshade is in a ring-shaped structure; the radiator and the light source component are mounted in the lampshade; the outer cambered surface of the radiator is bonded with the inner wall of the lampshade; and the lamp caps are mounted at the two ends of the lampshade to seal the lampshade. The LED tubular lamp provided by the invention has the advantages that since the lampshade is in the ring-shaped structure, the radiator and the light source component can be mounted in the lampshade; and the two ends of the lampshade are sealed by the lamp caps, so water and dust can be effectively prevented from entering into the lampshade, the service life of the LED tubular lamp can be prolonged and the light emitting effect of the LED tubular lamp can be improved.

Description

technical field [0001] The invention relates to LED lighting technology, in particular to an LED tube lamp. Background technique [0002] Existing LED (light emitting diode, Light Emitting Diode, referred to as LED) tube lamps include a lamp holder, a light source board, a radiator and a semi-tubular lampshade, the lengths of the lampshade, the light source board and the radiator are basically the same, and the cross section of the radiator is a semicircle Shape, the outer surface has zigzag or rectangular fins to increase the heat dissipation area and improve heat dissipation efficiency. [0003] When assembling, the light source board is fixedly connected on the installation plane of the radiator, the lampshade is covered on the light source board, and the two ends of the radiator and the lampshade are fixedly installed in the shell of the lamp holder respectively, and the lamp holder and the lamp holder are usually bonded or threaded. The radiator and lampshade are fixed...
