LED tube lamp and lamp holder thereof

Abstract

The invention discloses a lamp holder. The lamp holder comprises a lamp holder main body in the shape of a rotary shell, a binding post fixedly connected with the bottom wall of the lamp holder main body, and a fastener, wherein the fastener comprises an elongated fastener main body; one end of the fastener main body in the length direction is fixedly connected with the inner side wall of the bottom wall of the lamp holder main body; the other end of the fastener main body is provided with a bent hook shaped embossment; an annular boss is formed on the inner wall of the side wall of the lamp holder main body; at least one fastening slot is formed on the boss; and the length of the fastener is greater than a distance from the boss to the bottom wall of the lamp holder main body. The lamp holder can be fixedly connected with the heat dissipater and a lampshade effectively, so that the installation precision is improved, and the lamp holder is convenient to install; moreover, as the lampholder are connected with the heat dissipater and the lampshade tightly and stably, dusts can be prevented from entering an LED tube lamp, and the light emitting efficiency and the service life of the LED tube lamp can be guaranteed. The invention also discloses an LED tube lamp arranged on the lamp holder.

Description

technical field [0001] The invention relates to the technology of lighting appliances, in particular to a lamp holder of an LED tube lamp. In addition, the present invention also relates to an LED tube lamp equipped with the above lamp cap. Background technique [0002] At present, under the general environment of the national energy conservation and emission reduction policy and the strong demand of individuals for energy conservation, people have widely used LEDs (light-emitting diodes) as new energy-saving light sources. In home lighting and outdoor decorative lighting, LED energy-saving lamps, especially LED tube lamps, have been widely used. It is an inevitable trend for LED tube lamps to replace existing ordinary incandescent tube lamps as lighting appliances. [0003] Usually, the LED tube lamp includes a lamp holder, a light source board, a radiator and a semi-tubular lampshade. The length of the lampshade, the light source board and the radiator are basically the s...

Problems solved by technology

[0006] Moreover, because the lampshade and radiator are not firmly connected with the lamp holder, dust is easy to enter, which reduces the luminous efficiency and service life of the LED tube lamp

[0007] In addition, since the radiator and lampshade are installed inside the lamp housing, it is not easy to control the amount of entry, which will lead to inconsistent lengths of the produced LED tube lamps, which cannot meet the standardization requirements, and the scrap rate is high, which increases the production cost.
