Description

Technical Field

[0001] This utility model relates to a light-emitting module, specifically a low-loss semiconductor light-emitting module. Background Technology

[0002] With the continuous advancement of science and technology, semiconductor lighting is increasingly being used in various industries due to its advantages such as high efficiency, energy saving, environmental friendliness, and ease of maintenance. It utilizes solid-state semiconductor chips as the light-emitting material, releasing excess energy through carrier recombination to induce photon emission, thus directly emitting light. Existing semiconductor lighting fixtures typically involve directly soldering multiple semiconductor lamps onto a circuit board for use.

[0003] However, existing semiconductor lamps typically involve soldering multiple semiconductor lamps directly onto a circuit board. Once fixed to a wall, these lamps can usually only illuminate in one direction, which limits the lighting direction and the utilization of the light source. This affects people's lighting needs and reduces the efficiency of the light source. Therefore, a low-loss semiconductor light-emitting module is proposed. Utility Model Content

Detailed Implementation

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model discloses a low-loss semiconductor light-emitting module, including a housing 4. A first limiting plate 3 is fixedly connected inside the housing 4. A limiting cylinder 2 is fixedly connected to the outer surface of the first limiting plate 3. A second motor 7 is slidably connected to the inner wall of the housing 4. A first threaded rod 13 is fixedly connected to the output end of the second motor 7. Two first fixing blocks 9 are threadedly connected to the surface of the first threaded rod 13. The surface of the first fixing blocks 9 is slidably connected to the inner wall of the housing 4. A second limiting plate 10 is provided inside the housing 4. A first sliding groove 24 is opened on the surface of the second limiting plate 10. The surface of the first fixing blocks 9 is slidably connected to the inner wall of the first sliding groove 24, providing space for the first fixing blocks 9 to slide up and down.

[0024] The second limiting plate 10 is fixedly connected to the side away from the first fixing block 9 by a matrix arrangement of first limiting blocks 11. A second rotating ball 12 is embedded inside the first limiting block 11. A connecting rod 8 is fixedly connected to the outer surface of the second rotating ball 12. A first rotating ball 5 is embedded inside the limiting cylinder 2. The outer surface of the middle position of the connecting rod 8 is fixedly connected to the interior of the first rotating ball 5. A lamp bead 1 is fixedly connected to one end of the connecting rod 8. The number of connecting rods 8, first rotating balls 5, and second rotating balls 12 corresponds one-to-one with the number of first limiting blocks 11. The first threaded rod 13 is rotated by rotating the second motor 7 in both forward and reverse directions. The threaded transmission between the first threaded rod 13 and the first fixed block 9 enables the first fixed block 9 to move in the left and right directions within the housing 4, thereby driving the second limiting plate 10 to move. At this time, the limiting cylinder 2 limits the first rotating ball 5 under the limiting action of the first limiting plate 3, and the second rotating ball 12 rolls inside the first limiting block 11. Under the drive of the first limiting block 11, the connecting rod 8 rotates in the left and right angle direction. The first rotating ball 5 rolls in the limiting cylinder 2, and the lamp bead 1, which is fixedly connected to the connecting rod 8, rotates in the left and right direction, thereby changing the illumination direction of the lamp bead 1.

[0025] The inner wall of the housing 4 is slidably connected to a mounting block 23, and one end of the first threaded rod 13 is rotatably connected to the inside of the mounting block 23, providing a mounting point for the first threaded rod 13.

[0026] The inner wall of the housing 4 is slidably connected to a first motor 6. The output end of the first motor 6 is fixedly connected to a second threaded rod 19. The surface of the second threaded rod 19 is threadedly connected to two second fixing blocks 21. The surface of the second limiting plate 10 is provided with a second sliding groove 25. The surface of the second fixing block 21 is slidably connected to the inner wall of the second sliding groove 25, providing space for the second fixing block 21 to move left and right. The output end of the first motor 6 passes through the surface of a first fixing block 9 and is rotatably connected to its interior.

[0027] The housing 4 has a slide rod 20 fixedly connected inside, and a third fixing block 22 is slidably connected to the surface of the slide rod 20. One end of the second threaded rod 19 is rotatably connected to the surface of the third fixing block 22, providing a stable mounting point for the second threaded rod 19.

[0028] A third motor 16 is fixedly connected inside the housing 4. The output shaft of the third motor 16 is fixedly connected to a connecting cylinder 17. A fan blade 15 is fixedly connected to the outer surface of the connecting cylinder 17. A protective cover 18 is fixedly connected inside the housing 4. A ring-shaped ventilation hole 14 is provided on the back of the housing 4. By starting the third motor 16, the fan blade 15 is driven to rotate, and external cold air is blown into the device through the ventilation hole 14 to reduce the temperature inside the device and increase the service life of the lamp beads 1 inside the device.

[0029] Secondly, the first motor 6, the second motor 7, and the third motor 16 are all micro motors, which can be R140 motors, to ensure the normal assembly of the device. In addition, power supply, wires, controller and other structures are also provided to match them. Since they are not the main structures, they will not be described in detail.

[0030] During operation, the first threaded rod 13 is driven to rotate by rotating the second motor 7 in both forward and reverse directions. The threaded transmission between the first threaded rod 13 and the first fixed block 9 enables the first fixed block 9 to move in the left and right directions, further driving the second threaded rod 19 to move in the left and right directions. Simultaneously, the first motor 6 slides within the housing 4, driving the second fixed block 21 to slide in the second slide groove 25. While the first fixed block 9 moves, the push of the first fixed block 9 against the inner wall of the first slide groove 24 causes the second limiting plate 10 to move. At this time, due to the limiting action of the first limiting plate 3, the limiting cylinder 2 moves against the first rotating ball 5. The first rotating ball 12 rolls inside the first limiting block 11 and, driven by the first limiting block 11, causes the connecting rod 8 to rotate in the left and right angular direction. The first rotating ball 5 rolls in the limiting cylinder 2, and the lamp bead 1, which is fixedly connected to the connecting rod 8, rotates in the left and right direction. Similarly, the forward and reverse rotation of the first motor 6 enables the lamp bead 1 to rotate in the up and down direction, thereby changing the illumination direction of the lamp bead 1 and improving the utilization efficiency of the light source. At the same time, the third motor 16 is started to drive the fan blade 15 to rotate, blowing external cold air into the device through the ventilation hole 14 to reduce the temperature inside the device and increase the service life of the lamp bead 1 inside the device.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
