Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and more specifically, to a multi-layer light strip. Background Technology

[0002] An LED light is an electroluminescent semiconductor chip that is fixed to a support with silver or white glue. Then, silver or gold wires are used to connect the chip and the circuit board. The chip is sealed with epoxy resin to protect the internal core wires. Finally, a housing is installed. LED lights are widely used in the lighting industry. Whether in homes, offices, or shops, LED lights provide bright light. Compared with traditional incandescent bulbs, LED lights are more energy-efficient and have a longer lifespan.

[0003] Chinese Patent Announcement No. CN221526358U discloses a multi-layered light strip. This solution uses special mounting buckles on the upper and lower sides of the LED beads, along with fixed-spaced mounting circuit strips, to sequentially install and arrange the LED beads. Through the buckle structure, the LED beads on two light strips can be staggered and overlapped to form a multi-layered light strip. This combination is not only structurally stable and sturdy, but can also be freely stacked according to specific installation needs. However, in practical implementation, the following defects still exist: the light strip uses a splicing method to use multiple individual parts to form the light strip. If one of them malfunctions during use, it will affect the overall effect. Furthermore, when the spliced ​​light strip emits light, there will be a certain gap in the middle, and it cannot be completely continuous.

[0004] Therefore, a multi-layered light strip is proposed to address the above problems. Utility Model Content

[0029] Example:

[0030] Please see Figure 1-5 A multi-layer light strip includes a power receiving box 1, with three power receiving ports 2 at the front end of the power receiving box 1, a switch 3 fixedly connected to the front end of the power receiving box 1, a light-emitting mechanism 4 fixedly connected to the outer surface of the power receiving box 1, and a blocking mechanism 5 slidably connected inside the light-emitting mechanism 4.

[0031] This solution connects the light-emitting mechanism 4 to three power ports 2 and uses a switch 3 to control the function of the light-emitting mechanism 4. When the switch 3 is turned on, the light-emitting mechanism 4 will emit light. The light-emitting mechanism 4 itself is a single-layer light strip with double-sided light emission. By using two blocking mechanisms 5 to partially block it, the light-emitting mechanism 4 can emit light in multiple layers.

[0032] Please see Figure 2-4 The light-emitting mechanism 4 includes two positioning plates 41. Each of the two positioning plates 41 has several screw holes 42 at the ends that are close to each other. The ends that are far apart from each other are fixedly connected to a connecting component 43 by bolts. The inner surfaces of the two positioning plates 41 are slidably connected to a light-emitting component 44.

[0033] The connecting component 43 includes a connecting frame 431. The upper and lower walls of the inner cavity of the connecting frame 431 are provided with several screw holes 435. The upper and lower walls of the inner cavity of the connecting frame 431 are respectively fixedly connected to the ends of the two positioning plates 41 that are far apart from each other by bolts. The front end of the connecting frame 431 is provided with a square groove 432. The inner surface of the square groove 432 is fixedly connected to the outer surface of the electrical box 1. Two limit rods 433 are fixedly connected to the inner surface of the connecting frame 431. The inner surface of the connecting frame 431 is provided with four sliding grooves 434.

[0034] The light-emitting component 44 includes a circuit board 441. The front end of the circuit board 441 is fixedly connected to the rear end of the power receiving box 1. The outer surface of the circuit board 441 is slidably connected to the inner surface of the two positioning plates 41. Several pins 442 are fixedly connected to both ends of the circuit board 441. Several LED chips 443 are fixedly connected to the ends of the several pins 442 that are far apart from each other. Several lamp beads 444 are fixedly connected to the outer surface of the several LED chips 443. Several resistors 445 are fixedly connected to both ends of the circuit board 441.

[0035] This solution uses two positioning plates 41 to fix the position of the circuit board 441 and connects the circuit board 441 to the power box 1. When the light strip is powered from the three power ports 2, the switch 3 is pressed and the power is transferred to the circuit board 441. The circuit board 441 sends the power to several LED chips 443, which in turn control several LED beads 444 to emit light. Since the top and bottom ends and the front and back ends of the circuit board 441 are blocked by the connecting frame 431, the light from the LED beads 444 can only pass through the unblocked parts on the left and right sides of the connecting frame 431 when they emit light, forming a light strip that emits light from both sides.

[0036] Please see Figure 1 and Figure 5 The shielding mechanism 5 includes a pull rod 51, with a lampshade plate 52 fixedly connected to the rear end of the pull rod 51. Slide strips 53 are fixedly connected to both the upper and lower ends of the lampshade plate 52. The outer surfaces of the four slide strips 53 are slidably connected to the inner surfaces of the four slide grooves 434 respectively. Several light-shielding strips 54 are slidably connected to the inner cavity of the lampshade plate 52.

[0037] This solution achieves layered lighting by inserting light-shielding strips 54 into the inner surface of the lampshade plate 52. The position of the inserted light-shielding strips 54 can be adjusted according to specific needs. After adjustment, hold the pull rod 51 and align the two sliders 53 with the positions of the two slide grooves 434 respectively. Push from back to front so that the two sliders 53 can slide forward along the inner surface of the two slide grooves 434. Push until the front end of the two sliders 53 contacts the rear end of the limiting rod 433. At this time, the light that was originally emitted to both sides will be transformed into layers of light with the cooperation of the lampshade plate 52 and several light-shielding strips 54, so that the light strips can emit light in multiple layers.

[0038] It should be noted that the specific installation methods, circuit connection methods, and control methods of the power box 1, switch 3, circuit board 441, LED chip 443, lamp bead 444, and resistor 445 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0039] Working principle: When using the light strip, the external power supply is connected to the light-emitting mechanism 4 through the three power ports 2 to supply power. After power is supplied, the switch 3 is pressed, and the power is transferred to the circuit board 441. The circuit board 441 sends the power to several LED chips 443, which control several LED beads 444 to emit light. Since the top and bottom ends and the front and back ends of the circuit board 441 are blocked by the connecting frame 431, the light from the LED beads 444 can only pass through the unblocked parts on the left and right sides of the connecting frame 431 when they emit light, forming a light strip that emits light from both sides. Then, a light-shielding strip 54 is inserted into the inner surface of the lamp cover plate 52. The position of the light-shielding strip 54 can be adjusted according to specific needs. After adjustment, hold the pull rod 51 and use the cooperation of the two sliders 53 and the two sliding grooves 434 to insert the lamp cover plate 52 into the connecting frame 431. At this time, the light that was originally emitted to both sides will become layers of light under the cooperation of the lamp cover plate 52 and the light-shielding strips 54, so that the light strip can emit light in multiple layers.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
