Description

Technical Field

[0002] As we all know, TV backlight lens is an auxiliary lighting device widely used in fields such as TV backlight and light box backlight. In most cases, TV backlight lens is not used individually, but in batch array. To facilitate the application of TV backlight lens, we propose a combined TV backlight lens module.

[0003] After searching, the invention patent with Chinese patent application number CN201821449872.6 discloses a TV backlight lens, which is roughly described as including a lens body, a light emitting surface is provided on the top of the lens body, a circular cavity with an opening downward is provided on the bottom of the lens body, the inner wall of the circular cavity is an arc-shaped surface as the light incident surface, the opening of the circular cavity is used as the installation port of the LED lamp beads, and a diffuse reflection surface is provided on the bottom of the lens body. The edges of the light emitting surface and the bottom surface are connected by a vertical wall surface. When it is in use, light is irradiated from the light incident surface of the arc-shaped circular cavity inner wall surface, and refracted by the diffuse reflection surface, and irradiated from the light emitting surface. The circular cavity disperses the light, the illumination is uniform, the brightness is high, and no light spots are generated. The diffuse reflection surface reflects the refracted light to the light emitting surface for illumination, thereby increasing the brightness, reducing stray light and residual light, and improving the light softness, thereby making the light illuminated by the TV softer and more uniform, and providing better visual effects.

The left and right ends of the pushing strip frame 16 are fixedly connected with bottom positioning mounting ears 28. The left and right ends of the mounting cover frame 17 are fixedly connected with top positioning mounting ears 29. By superimposing and pressing the middle positioning mounting ears 27, the bottom positioning mounting ears 28 and the top positioning mounting ears 29, on the one hand, a positioning mounting ear 27, a bottom positioning mounting ear 28 and a top positioning mounting ear 29 are formed. The combined TV backlight lens module is positioned and installed relative to the installation site. On the other hand, the mutually cooperating middle clamp frame 2, the pushing bar frame 16 and the installation cover frame 17 form relative positioning with respect to the relative cooperating positions. The middle positioning mounting ear 27, the bottom positioning mounting ear 28 and the top positioning mounting ear 29 are all fixedly connected with auxiliary adjustment extension plates 30. The three auxiliary adjustment extension plates 30 are arranged to rotate and stagger with each other to assist in pinching and grasping force when the middle positioning mounting ear 27, the bottom positioning mounting ear 28 and the top positioning mounting ear 29 are adjusted to slide relative to each other. A side connection opening 33 is opened on a middle positioning mounting ear 27 located on the right side, and the side connection opening 33 provides adjustment space for the rightmost protrusion block 24 among the multiple protrusion blocks 24.

[0038] The access circuit board 8 and LED lamp beads 9 in this embodiment are conventional equipment purchased on the market and known to technical personnel in this field. The contact electrode strip 6 and the sliding electrode rod 10 are both made of conductive materials. In this patent, we only use them and do not improve their structure and function. Therefore, the specific structure and content of the contact electrode strip 6, the sliding electrode rod 10, the access circuit board 8 and the LED lamp beads 9 will not be repeated, and the middle clamp frame 2 is embedded with a unified power supply line matching the contact electrode strip 6.

[0039] In summary, the working principle of the combined TV backlight lens module is that, when in use, the combined TV backlight lens module is first assembled as a whole into the following Figure 1 In this state, multiple LED lamp beads 9 are respectively inserted into the light entrance holes 18 at the bottom ends of multiple TV backlight lenses 1. Multiple TV backlight lenses 1 are provided with a light emitting surface, a step side surface, and a bottom surface, and the step side surface is connected to the light emitting surface and the bottom surface. When in use, Figure 1The combined TV backlight lens module in the state shown can be positioned and installed and electrically installed relative to the installation site. The positioning installation is achieved by inserting external bolts into the overlapping holes formed by the middle positioning mounting ear 27, the positioning mounting ear and the top positioning mounting ear 29, and screwing the bolts into the installation surface of the installation site to fix them. The electrical equipment forms an electrical connection with the external power supply circuit through a unified power supply line matching the contact electrode strip 6. During actual operation, the external power supply circuit realizes the matching power supply of multiple contact electrode strips 6 through the unified power supply line, and forms the power supply of the LED lamp beads 9 through the matching of multiple contact electrode strips 6 with multiple sliding electrode rods 10. When the LED lamp beads 9 are powered on, they generate light. The light generated by the LED lamp beads 9 is guided and reflected by the TV backlight lens 1 to enrich the illumination area of ​​the LED lamp beads 9. Once the LED lamp beads 9 are damaged due to the use and consumption, the combined TV backlight lens module can be removed relative to the installation location, and the push bar frame 16 is pushed to the left relative to the middle clamp frame 2 to achieve the synchronous position movement of the multiple guide plate heads 26 relative to the middle clamp frame 2. Due to the relative pushing effect of the multiple guide plate heads 26 and the multiple elastic plates 5, the multiple elastic plates 5 will form elastic downward bends in the multiple middle openings 4, so that the corresponding contact electrode strips 6 act on The pushing effect of the corresponding sliding electrode rod 10 fails. In this state, the elastic pressure plate 15 will push the lifting frame 7 to lower its height relative to the middle clamp frame 2, so that the multiple LED lamp beads 9 can be respectively withdrawn from the multiple light entrance holes 18. After the multiple LED lamp beads 9 are respectively withdrawn from the multiple light entrance holes 18, the mounting cover frame 17 is pushed relative to the middle clamp frame 2, so as to facilitate the TV backlight lens 1 to be separated from the multiple LED lamp beads 9 respectively. After that, the lifting frame 7 integrated with the damaged LED lamp bead 9, the circuit board 8 and the sliding electrode rod 10 are replaced as a whole structure, so as to realize the replacement of the damaged LED lamp bead 9. After the replacement is completed, first refer to the aforementioned pushing relative to the middle clamp frame 2. The cover frame 17 is installed in the opposite direction of movement, so that the multiple TV backlight lenses 1 are synchronously aligned with the multiple LED lamp beads 9, and finally the pushing frame 16 is pushed to the right relative to the middle clamping frame 2, so that the multiple guide plate heads 26 are moved to the right relative to the multiple elastic plates 5, and the pushing effects of the multiple guide plate heads 26 relative to the multiple elastic plates 5 are invalid. Under the action of the elastic deformation recovery of the multiple elastic plates 5, the multiple LED lamp beads 9 are reinserted relative to the multiple light entrance holes 18, and in the process of replacing the LED lamp beads 9, since the elastic pressure plate 15 has a certain elasticity, it provides the necessary prerequisite for the replacement of the lifting frame 7.
