Description

Technical Field

[0001] This utility model relates to the field of LED light source technology, specifically to an LED backlight display module. Background Technology

[0002] LED light strip modules are backlights composed of multiple LEDs, offering advantages such as high brightness, energy efficiency, and long lifespan. Their high brightness provides ample light, making screen displays clearer and brighter. Furthermore, LED light strip modules consume little energy, have a long lifespan, contain no harmful substances, meet environmental standards, and exhibit good uniformity.

[0003] In existing LED backlight display modules, the positions of the LED chips are mostly fixed by the module's structure and cannot be moved. When some LED chips are damaged and there are no replacement chips available temporarily, if the damaged chips are concentrated at one end of the LED strip, it can easily cause the bright and dark areas of the LED strip to separate, severely affecting the backlight effect.

[0004] Therefore, we propose to design an LED backlight display module. Utility Model Content

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0024] Please see Figure 1-3 This utility model provides an LED backlight display module, including a base 1, with terminals 2 fixedly connected to both ends of the base 1, and positioning strips 3 provided on both sides of the bottom inside the base 1.

[0025] The positioning strip 3 includes a metal spring 301 fixed to the bottom of the base 1. An insulating rubber sleeve 302 is fixedly connected to the outer wall of the metal spring 301. The metal spring 301 and the insulating rubber sleeve 302 can provide elasticity to position the LED beads 5.

[0026] A backlight module 4 is installed at the center of the bottom of the base 1.

[0027] The backlight module 4 includes a junction box 401, in which a positive wire 402 and a negative wire 403 are embedded and fixedly connected. The positive wire 402 and the negative wire 403 are respectively connected to two terminals 2 outside the base 1, so as to facilitate the connection of the backlight module 4 inside the base 1 to an external power source.

[0028] A mounting base 404 is fixedly connected to the top of the terminal block 401. The mounting base 404 has a mounting groove 405 inside. Positive terminal 406 and negative terminal 407 are respectively embedded and fixedly connected to the two sides of the inner wall of the mounting groove 405.

[0029] There are several positive terminals 406 and several negative terminals 407. The bottom of each positive terminal 406 is connected to the corresponding positive line 402, and the bottom of each negative terminal 407 is connected to the corresponding negative line 403. The positive terminals 406 and negative terminals 407 in the several mounting slots 405 are connected in parallel to the terminal block 401.

[0030] An LED bead 5 is inserted into the mounting slot 405. The two ends of the LED bead 5 are tightly fitted with two positioning strips 3, which facilitates the fixing of the LED bead 5.

[0031] The LED bead 5 has positive and negative terminals on both sides. The positive and negative terminals on both sides of the LED bead 5 are connected to the positive terminal 406 and the negative terminal 407 respectively, which enables hot-swapping of the LED bead 5.

[0032] In use, several LED beads 5 are inserted into the corresponding mounting slots 405. When the terminal 2 is connected to the external power supply, the LED beads 5, which serve as the backlight, are lit up together. The LED beads 5 are connected in parallel to the circuit, so even if some LED beads 5 are damaged, it will not affect the lighting of the other beads.

[0033] When a lamp bead is damaged, the staff can open the base 1 and hot-swap the LED bead 5. During the operation, the positioning strip 3 on one side can be pushed open to slide out the damaged lamp bead. Then the remaining lamp beads are evenly distributed in the mounting base 404. Although some LED lamp beads 5 are lost at this time, by adjusting the position of the remaining lamp beads, the light source can be kept as uniform and stable as possible.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
