LED (light-emitting diode) lamp tube

Abstract

The invention discloses an LED (light-emitting diode) lamp tube. The LED lamp tube comprises a lamp tube body, a left lamp holder and a right lamp holder, wherein pins are respectively arranged on the left lamp holder and the right lamp holder, and a power supply circuit board is arranged in the right lamp holder; the lamp tube body is of an all-plastic structure, and a support part concavely formed inwards is arranged on the lamp tube body; an LED base plate is arranged on the support part; a plurality of LED light sources are uniformly distributed on the LED base plate, and an inserting-connection block is arranged at the right end of the LED base plate; an inserting-connection notch is formed in the inserting-connection block; an inserting-connection head matched with the inserting-connection notch is arranged on the power supply circuit board, and contact pins are arranged on the power circuit board; the contact pins are arranged in the pins of the right lamp holder in an inserting mode, and are connected with the pins of the right lamp holder in a riveting mode. The support part concavely formed inwards on the lamp tube body can effectively increase the strength, the LED lamp tube is unlikely to be deformed, the weight is lightened, and the cost is reduced; moreover, the power supply circuit board and the lamp holders are riveted by adopting the contact pins, and the LED base plate and the power supply circuit board are in inserting connection by adopting the inserting-connection plug, so that the connection reliability is improved.

Description

technical field [0001] The invention relates to the field of lamps, in particular to an LED lamp tube. Background technique [0002] As a new type of light source, LED lamps have the advantages of small size, low energy consumption, strong practicability, high stability, short response time and no pollution to the environment, and are widely used in the field of lighting decoration. LED lamp tube is a kind of LED lamp, which is composed of lamp tube body, lamp caps at both ends and LED light source. The LED lamp tubes on the existing market have the following disadvantages: [0003] 1. The lamp head is fixed by screws or riveted by copper sheets, and connected with the power supply circuit board by manual winding and soldering. [0004] 2. If the lamp tube made of plastic is not supported by aluminum profiles inside, most of the lamp tubes will be deformed after heating. After a period of use, it will lack aesthetics and may affect the performance of the lamp. If the alumi...
