An LED lighting lamp with light-shielding function

Abstract

This utility model provides an LED lighting lamp with a light-shielding function, including a lamp holder, an LED lighting panel, a light-shielding plate, and a moving mechanism. The light-shielding plate is slidably disposed above the LED lighting panel. The light-shielding plate has light-transmitting holes corresponding to the number and position of the LED beads on the LED lighting panel. The moving mechanism drives the light-shielding plate to move back and forth in a straight line along the LED lighting panel, so that the light-transmitting holes on the light-shielding plate coincide with or are offset from the positions of the LED beads on the LED lighting panel. This allows the light to be turned on or off without turning off the power of the LED lighting panel, thus solving the problem of glaring light affecting rest during rest periods when the power switch of the lamp cannot be turned off.

[0001] This utility model relates to the field of lighting technology, specifically to an LED lighting lamp with a light-shielding function. Background Technology

[0002] In daily life, some events and ceremonies require lights to be kept on for a period of time, during which the power switches of the lights cannot be turned off. However, when lights (LED lights) are on for extended periods, the light can be quite glaring, affecting people who are resting. Utility Model Content

[0003] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide an LED lighting lamp with a light-shielding function.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This application provides an LED lighting lamp with a light-shielding function, including:

[0006] Lamp holder,

[0007] An LED lighting panel is installed inside the lamp holder, and the LED lighting panel is provided with multiple LED beads;

[0008] A light-shielding plate has multiple light-transmitting holes corresponding to the multiple LED beads, and the light-shielding plate is horizontally slidably installed on the upper surface of the LED lighting panel;

[0009] A moving mechanism, connected to the light-shielding plate, is used to push the light-shielding plate to move linearly back and forth, in order to block or open the lamp beads.

[0010] Furthermore, the moving mechanism includes a mounting base, a push rod, and a locking assembly. The mounting base is fixedly installed on the bottom surface of the LED lighting panel. The mounting base has a mounting hole. A first connecting hole is opened on the surface of the mounting base near the LED lighting panel. A second connecting hole is opened on the LED lighting panel at the position corresponding to the first connecting hole. The first connecting hole communicates with the mounting hole. The push rod is slidably installed in the mounting hole. A connecting block is provided at the bottom surface of the light shield. The connecting block passes through the first connecting hole and the second connecting hole and is fixedly connected to the push rod. The locking assembly is disposed between the mounting base and the push rod and is used to lock the position of the push rod in the mounting base.

[0011] Furthermore, the locking assembly includes an arrow-shaped groove on the push rod away from the LED lighting panel, a locking block located in the middle of the groove, and a fixing rod fixed to the mounting base. A sliding groove is formed between the locking block and the inner wall of the groove. One end of the fixing rod extends vertically downward into the inner cavity of the mounting hole and is located near the top of the sliding groove. The locking block has a locking groove that engages with the downwardly extending end of the fixing rod, and the locking groove communicates with the sliding groove.

[0012] Furthermore, one end of the push rod extends to the outer edge of the LED lighting panel.

[0013] Furthermore, the other end of the push rod is provided with a spring mounting part, on which a spring is fitted. The mounting hole is a blind hole. The spring mounting part is installed at the closed end of the mounting hole. One end of the spring is mounted against the closed end of the mounting hole. The other end of the spring is fixedly installed on the spring mounting part.

[0014] Furthermore, the spring mounting part is a rod-shaped structure with an outer diameter smaller than that of the push rod, and a stepped part is formed at the junction of the spring mounting part and the push rod, with the other end of the spring abutting against the stepped part.

[0015] Furthermore, it also includes a lampshade, which is fixedly mounted on the lamp holder.

[0016] The beneficial effects of this utility model are as follows:

[0017] By employing the aforementioned LED lighting panel with a light-shielding function, a light-shielding plate is slidably mounted above the LED lighting panel. The light-shielding plate has light-transmitting holes corresponding to the number and position of the LED beads on the LED lighting panel. A moving mechanism drives the light-shielding plate to move back and forth along a straight line along the LED lighting panel, so that the light-transmitting holes on the light-shielding plate coincide with or are offset from the positions of the LED beads on the LED lighting panel. This allows the light to be turned on or off without turning off the power to the LED lighting panel, thus solving the problem of glaring light affecting rest during rest periods when the power switch of the light fixture cannot be turned off.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0039] See appendix Figure 1 Appendix Figure 2 Appendix Figure 7 and attached Figure 8 and appendix Figure 11 As shown, this embodiment provides an LED lighting lamp 10 with a light-shielding function, including a lamp holder 100, an LED lighting panel 300, a light-shielding plate 400, and a moving mechanism 500.

[0040] In this embodiment, an LED lighting panel 300 is mounted on a lamp holder 100, and the LED lighting panel 300 includes a plurality of evenly spaced LED beads 301. A light-shielding plate 400 is horizontally slidably mounted above the LED lighting panel 300, meaning the light-shielding plate 400 can reciprocate linearly relative to the LED lighting panel 300. The light-shielding plate 400 is provided with light-transmitting holes 401 corresponding to the number and position of the LED beads 301 on the LED lighting panel 300. A moving mechanism 500 is connected to the light-shielding plate 400, and the moving mechanism 500 is used to push the light-shielding plate 400 to reciprocate linearly, thereby blocking or opening the LED beads 301. (Refer to the attached diagram.) Figure 3 To be continued Figure 6 As shown, when the light-shielding plate 400 is in its original position, the multiple light-transmitting holes 401 on the light-shielding plate 400 coincide with the positions of the multiple LED beads 301 on the LED lighting panel 300, and the light emitted by the LED beads 301 on the LED lighting panel 300 can be directly emitted outward through the light-transmitting holes 401. However, when the light-shielding plate 400 is pushed to the light-shielding position, the light-transmitting holes 401 on the light-shielding plate 400 are misaligned with the multiple LED beads 301 on the LED lighting panel 300. At this time, the light emitted by the LED beads 301 on the LED lighting panel is blocked by the light-shielding plate 400. Due to the opacity of the light-shielding plate 400 (the light-shielding plate 400 is made of opaque material), the light emitted by the LED beads 301 is blocked, preventing the light from being emitted directly, which is approximately equivalent to turning off the lights.

[0041] By utilizing a light-shielding plate 400 slidably disposed above the LED lighting panel 300, and the light-shielding plate 400 having light-transmitting holes 401 corresponding to the number and position of the LED beads 301 on the LED lighting panel 300, the light-shielding plate 400 is driven to move back and forth linearly along the LED lighting panel 300 by a moving mechanism 500, so that the light-transmitting holes 401 on the light-shielding plate 400 coincide with or are offset from the positions of the LED beads 301 on the LED lighting panel 300. This allows the light to be turned on or off without turning off the power of the LED lighting panel 300, thus solving the problem of glaring light affecting rest during rest periods when the power switch of the light fixture cannot be turned off.

[0042] See attached document Figure 7 To be continued Figure 10 and appendix Figure 12 and attached Figure 13 As shown, in this embodiment, the moving mechanism 500 specifically includes a mounting base 501, a push rod 502, and a locking assembly. The mounting base 501 is fixedly installed on the bottom surface of the LED lighting panel 300. The mounting base 501 has mounting holes arranged laterally. A pair of first connecting holes are opened on the surface of the mounting base 501 near the surface of the LED lighting panel 300. A pair of second connecting holes are opened on the LED lighting panel 300 at positions corresponding to the pair of first connecting holes. The pair of first connecting holes communicate with the mounting holes. The push rod 502 is slidably installed in the mounting holes. A pair of connecting blocks are provided on the bottom surface of the light shield 400. The pair of connecting blocks pass through the first connecting holes and the second connecting holes respectively and are connected to the push rod 502. A pair of slots 5022 are provided on the push rod 502. One end of the pair of connecting blocks is locked in the pair of slots 5022. In this way, the lateral movement of the push rod 502 can synchronously drive the movement of the light shield 400 through the connecting plate. A locking assembly is provided between the mounting base 501 and the push rod 502 to lock the position of the push rod 502 within the mounting base 501.

[0043] See attached document Figure 9 and attached Figure 10 As shown, in this embodiment, the light-shielding plate 400 is fixedly mounted on the push rod 502 by a connecting block. The bottom surface of the light-shielding plate 400 does not contact the upper surface of the LED lighting panel 300, and a small gap is formed between them. In this way, the light-shielding plate 400 can move linearly back and forth along the upper surface of the LED lighting panel 300 under the lateral push of the push rod 502. It can be understood that the gap between the bottom surface of the light-shielding plate 400 and the upper surface of the LED lighting panel 300 is controlled by the height of the connecting block. That is, the larger the height of the connecting block, the larger the gap, and vice versa.

[0044] See attached document Figure 8 To be continued Figure 10 and appendix Figure 12 As shown, specifically, the locking assembly includes an arrow-shaped groove on the push rod 502 away from the LED lighting panel 300, a locking block 506 located in the middle of the groove, and a fixing rod 503 fixed to the mounting base 501. A sliding groove 505 is formed between the outer edge of the locking block 506 and the inner wall of the groove. One end of the fixing rod 503 extends vertically downward into the inner cavity of the mounting hole and is located above the sliding groove 505. The locking block 506 has a locking groove 507 that engages with the downwardly extending end of the fixing rod 503. The locking groove 507 is connected to the sliding groove 505.

[0045] When the push rod 502 moves laterally along the mounting hole, the slide groove 505 on the push rod 502 will also move laterally in sync with the push rod 502. Since the fixed rod 503 is fixed on the mounting base 501, the fixed rod 503 is in a fixed state. As the push rod 502 moves laterally, the slide groove 505 will slide relative to the vertically downward extending end of the fixed rod 503. The vertically downward extending end of the fixed rod 503 will slide into or out of the locking groove 507, thereby locking or unlocking the push rod 502. For example, when the LED lighting board 300 is to be shielded from light, the push rod 502 moves laterally along the mounting hole. At this time, the slide 505 slides along the vertically downward extending end of the fixing rod 503. When the slide 505 moves to the position of the vertically downward extending end of the fixing rod 503, the vertically downward extending end of the fixing rod 503 (its slender rod-shaped structure gives it good elasticity) will slide into the locking groove 50 through the slide 505. In step 7, the locking mechanism is engaged. Since the vertically downward extending end of the fixing rod 503 is inserted into the locking groove 507, the push rod 502 can no longer move laterally in that direction, thus locking the push rod 502. Simultaneously, this position causes the light-transmitting hole 401 on the light-shielding plate 400 to be misaligned with the LED bead 301 on the LED lighting panel 300, achieving a light-shielding effect. To turn on the LED bead 301 on the LED lighting panel 300, the push rod 502 is moved laterally in the opposite direction. 2. The locking groove 507 applies an outward pushing force to the vertically downward extending end of the fixing rod 503, causing the vertically downward extending end of the fixing rod 503 to tilt upward at an angle. As the push rod 502 moves laterally in the opposite direction, the upward tilt of the vertically downward extending end of the fixing rod 503 gradually increases and it disengages from the locking groove 507 and re-enters the sliding groove 505 on the outer edge of the latch block 506. Accompanied by the reverse lateral movement of the push rod 502, one end of the sliding groove 505 slides until the fixing rod 503 is vertical. After the downward extension reaches its final position, the slide 505 contacts the vertically downward extension of the fixed rod 503, hindering the slide 505 from moving further. At this point, the resistance to the movement of the push rod 502 increases, and the operator stops the movement of the push rod 502. At this time, the light shield 400 moves to its original position. The light-transmitting hole 401 on the light shield 400 coincides with the lamp bead 301 on the LED lighting panel 300. The light from the lamp bead 301 can be emitted outward through the light-transmitting hole 401 to achieve the lighting effect.

[0046] See attached document Figure 8 and attached Figure 9 As shown, in order to facilitate the operator's operation of the push rod 502, one end of the push rod 502 extends to the outer edge of the LED lighting panel 300, that is, one end of the push rod 502 extends outward a certain distance towards the outer edge of the LED lighting panel 300, so that the operator can press the push rod 502 with their fingers.

[0047] See attached document Figure 7 To be continued Figure 10 and appendix Figure 13 As shown, the other end of the push rod 502 is provided with a spring mounting part 5021, on which a spring 504 is fitted. The mounting hole is a blind hole, and the spring mounting part 5021 is installed at the closed end of the mounting hole. One end of the spring 504 is abutted against the closed end of the mounting hole, and the other end of the spring 504 is fixedly installed on the spring mounting part 5021. Specifically, the spring mounting part 5021 is a rod-shaped structure with an outer diameter smaller than that of the push rod 502. A stepped portion is formed at the junction of the spring mounting part 5021 and the push rod 502, and the other end of the spring 504 is abutted against the stepped portion.

[0048] The spring 504 is designed to facilitate the reset of the push rod 502 during the pressing process. That is, as described above, when the push rod 502 is in the locked position, the vertically downward extending end of the fixed rod 503 is engaged in the locking groove 507, and the light-transmitting hole 401 on the light shield 400 is exactly misaligned with the lamp bead 301 on the LED lighting panel 300 to achieve the light-shielding effect. At this time, the spring 504 is in a compressed state. When the light of the lamp bead 301 on the LED lighting panel 300 is turned on, the push rod 502 is moved laterally in the opposite direction. The locking groove 507 applies an outward pushing force to the vertically downward extending end of the fixed rod 503, causing the vertically downward extending end of the fixed rod 503 to tilt upward at an angle. After the vertically downward extending end of the fixed rod 503 disengages from the locking groove 507 and re-enters the sliding groove 505 on the outer edge of the locking block 506, the spring 504, which is in a compressed state, returns to its original length after losing the restriction of the locking groove 507. This pushes the push rod 502 to move laterally in the opposite direction, causing the push rod 502 to move back to its original position.

[0049] See attached document Figure 1 and 2 As shown, in some embodiments, a lampshade 200 is installed on the lamp holder 100 to improve the protection of the LED lighting panel 300.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
