Lamp tube device with electric connecting sleeve of winding body and light source module

Abstract

The invention relates to a lamp tube device with an electric connecting sleeve of a winding body and a light source module. The lamp tube device comprises a lamp tube body and the electric connecting sleeve of the winding body; wherein the lamp tube body has an end part and a guide wire extending outward from the end part. The position of the electric connecting sleeve of the winding body corresponds to the end part of the lamp tube body; the electric connecting sleeve of the winding body is electrically connected with the guide wire so as to transmit electric power into the lamp tube body from outside. The electric connecting sleeve of the winding body winds along the direction of an axle center of the lamp tube body and can carry out elastic or non-elastic stretching or compression along the direction of the axle center. Besides the lamp tube device, the light source module also comprises a lamp tube connecting seat which comprises a power end which is electrically connected with the electric connecting sleeve of the winding body to supply power so as to lead the lamp tube body to emit light. The lamp tube device and the light source module are easy to assemble, have better radiating effect, can reduce the damage of the lamp tube due to external force and can reduce the chance of tripping of the lamp tube from the connecting seat.

Description

technical field [0001] The invention relates to a lamp device and a light source module; specifically, the invention relates to a lamp device and a light source module used in a backlight module. Background technique [0002] Backlight modules are widely used in various products, such as liquid crystal displays, to provide light sources required by the products. In recent years, as the demand for liquid crystal displays increases, the technology of backlight modules is becoming more and more mature. As for the common backlight modules currently on the market, light tubes are still the main light source used in the backlight modules because of their low cost. [0003] In the traditional design, when assembling, the end of the lamp tube is first inserted into the connecting seat on the base plate, and then the guide wire protruding from the electrode of the lamp tube is connected to the terminal of the connecting seat by welding. From a production point of view, this design ...

Problems solved by technology

In addition, since the metal cap 30 is clamped by the spring socket 51, and the metal cap 30 tightly covers the end 11 of the lamp tube 10, the end of the lamp tube 10 will Part 11 and shrapnel socket 51 cannot move relative to each other in the axial and radial directions

Therefore, when the external force impacts the backlight module, the following two results will usually be caused: 1. The shrapnel socket 51 transmits the radial and axial external force to the metal cap 30, and the metal cap 30 transmits all the external force to the end of the lamp tube 10. 11, causing damage to the lamp tube 10; 2. The shrapnel socket 51 cannot hold the end 11 of the lamp tube 10, causing the lamp tube 10 to jump off from the shrapnel socket 51, resulting in interruption of electrical connection
