Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to an LED lighting device with adjustable light efficiency. Background Technology

[0002] LED lighting equipment is a solid-state lighting device that uses light-emitting diodes (LEDs) as its core and converts electrical energy into light energy through semiconductor chips. It has significant advantages such as high efficiency and energy saving, safety and environmental protection, long life, small size and high light quality, and is gradually becoming the main product in the new generation of lighting market. However, traditional LED lighting equipment is not easy to adjust the lighting effect according to different needs, resulting in poor adaptability when using LED equipment.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent with announcement number CN207316693U, announcement date 2018-05-04) provides an intelligent adjustable LED ceiling light, including a lamp holder and an LED lampshade. The lamp holder and LED lampshade are combined to form a closed LED ceiling light structure. The lamp holder is provided with uniformly distributed LED beads. An adjustable diffuser column is provided in the adjustment groove on the lamp holder within the gap between the LED beads. An adjustment device for the diffuser column is provided between the diffuser column and the lamp holder. The adjustment device includes an adjustment band and an adjustment main shaft. The diffuser column is uniformly fixed on the adjustment band. A fixed shaft and a connecting shaft are respectively provided on both sides of the lamp holder. The two ends of the adjustment band pass through the connecting shaft and are connected to the fixed shaft and the adjustment main shaft respectively. A detachable fixing device is symmetrically provided between the connecting blocks at both ends of the connection between the LED lampshade and the lamp holder. The light intensity of the ceiling light can be adjusted at any time, improving the comfort of using the LED ceiling light.

[0004] The aforementioned mechanism adjusts the light intensity by using a disassembly mechanism to adjust the lamp holder and lampshade. However, in actual use, each adjustment of the light intensity requires disassembling the lampshade and lamp holder, which makes the process of adjusting the light intensity too complicated and affects the convenience of adjustment. Utility Model Content

[0005] The purpose of this utility model is to provide an LED lighting device with adjustable light effect, so as to solve the problem mentioned in the background art that traditional LED lighting devices are not convenient to adjust the lighting effect according to different needs, resulting in poor adaptability of LED devices during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an LED lighting device with adjustable light efficiency, comprising a lamp housing, a connecting wire installed at the top of the lamp housing, and a junction box installed on the side of the connecting wire; a lamp shade is snapped into the lower end inside the lamp housing; an LED bead is disposed at the lower end inside the lamp housing, and a rotating snap-fit ​​mechanism for adjusting the angle of the LED bead is disposed at the middle position of the top of the lamp housing; heat sinks are disposed at both the front and rear ends of the top of the lamp housing, and an auxiliary heat dissipation mechanism for cleaning the heat sinks is disposed above the heat sinks; a lens is disposed below the LED bead, and disassembly and assembly mechanisms for installing the lens are disposed on both the left and right sides of the lens.

[0007] Furthermore, the rotating engagement mechanism includes a knob, which is located at the middle position of the top of the lamp housing. A limiting block is installed at the bottom of the knob, and the limiting block passes through and extends into the interior of the lamp bead. A first mating block is installed at the bottom of the limiting block, and a second mating block matching the first mating block is provided at the middle position of the top of the lamp bead.

[0008] Furthermore, the bottom end of the second mating block is in contact with the top end of the side of the first mating block, and the second mating block is symmetrical about the vertical central axis of the knob.

[0009] Furthermore, the disassembly and assembly mechanism includes a limiting frame, which is fixedly connected to the left and right sides of the lens. The limiting frame has a locking block on its side, and the inner side of the lamp housing has a slot that matches the locking block.

[0010] Furthermore, connecting springs are provided at both the front and rear ends of the card block, and the card block and the lamp housing are connected by the connecting springs to form an elastic structure.

[0011] Furthermore, the auxiliary heat dissipation mechanism includes a fixed frame, and a threaded rod is rotatably connected to one end of the fixed frame. A movable block is threadedly connected to the outer side of the threaded rod, and a cleaning brush that matches the heat sink is installed at the bottom end of the movable block.

[0012] Furthermore, a slider is fixedly connected to the top of the movable block, and the slider and the fixed frame are slidably connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By rotating the knob, the bottom of the knob can drive the limiting block to rotate synchronously. Since the limiting block is engaged in the middle position inside the lamp bead, the knob drives the lamp bead to rotate synchronously. When the lamp bead rotates above the lens, the angle at which the light passes through the lens is different, thereby achieving adjustment of the light effect and making it easy to quickly adjust the lighting effect according to the needs.

[0015] Furthermore, the limiting block at the bottom of the limiting block cooperates with and engages with the first mating block inside the lamp bead, so that when the knob is rotated, the lamp bead will be stably driven to rotate, improving the flexibility of light effect adjustment.

[0016] Furthermore, various lighting effects can be adjusted by disassembling and replacing the lens. Pull the clip out to the side to separate the clip from the slot, and then take the lens out from inside the lamp housing. When replacing a different lens, pull the clip inward to fix the position of the lens, and then remove the pulling force applied to the clip. This allows the clip to reset through the elastic force of the connecting spring and engage with the slot, thereby achieving the installation and fixation of the lens.

[0017] 2. The heat sink assists in heat dissipation for the LED light body. However, the heat sink is prone to attracting dust due to static electricity during heat dissipation, which can weaken its heat dissipation performance during subsequent use. Therefore, by rotating the handle, the threaded rod can be rotated. The threaded rod and the movable block are connected by a thread, allowing the threaded rod to rotate and move the movable block. The movable block, in turn, drives the cleaning brush to rotate, cleaning the outside of the heat sink and reducing dust residue. This effectively prevents the heat sink from weakening its heat dissipation performance due to dust accumulation.

[0018] Furthermore, during the movement of the movable block, the slider slides inside the fixed frame, thereby limiting the angle of the movable block during movement and preventing the movable block from deflecting its own angle due to the rotation of the threaded rod.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: As Figure 1 - Figure 5 The technical solution shown addresses the problem of poor adaptability in traditional LED lighting equipment due to the difficulty in adjusting lighting efficacy to meet different needs. This adjustable LED lighting device discloses a rotating locking mechanism, including a lamp housing 1. A connecting wire 2 is mounted on the top of the lamp housing 1, and a junction box 3 is mounted on the side of the connecting wire 2. A lampshade 4 is locked to the lower end inside the lamp housing 1. An LED bead 5 is disposed at the lower end inside the lamp housing 1, and a setting for adjusting the angle of the LED bead 5 is provided at the middle position of the top of the lamp housing 1. The rotating engagement mechanism includes a knob 12, which is located at the middle position of the top of the lamp housing 1. A limiting block 13 is installed at the bottom of the knob 12, and the limiting block 13 passes through and extends into the interior of the lamp bead 5. A first mating block 14 is installed at the bottom of the limiting block 13, and a second mating block 15 matching the first mating block 14 is provided at the middle position of the top of the lamp bead 5. The bottom of the second mating block 15 is in contact with the top of the side of the first mating block 14, and the second mating block 15 is symmetrical about the vertical central axis of the knob 12.

[0028] In this example, the lamp housing 1 is connected to the junction box 3 via the connecting wire 2, enabling the lamp housing 1 to be used. Simultaneously, the LED beads 5 inside the lamp housing 1 provide illumination, and the light passing through the lens 6 changes the lighting effect. As shown in the figure of the LED beads 5, rotating the knob 12 causes the bottom of the knob 12 to drive the limiting block 13 to rotate synchronously. Since the limiting block 13 is engaged in the middle position inside the LED beads 5, the knob 12 synchronously drives the LED beads 5 to rotate. By utilizing the rotation of the LED beads 5 above the lens 6, the angle at which the light passes through the lens 6 varies, thereby adjusting the lighting effect and facilitating quick adjustment of the lighting effect according to needs. Figure 5As shown, the limiting block 13 at the bottom of the limiting block 13 cooperates with and engages with the first docking block 14 on the inner side of the lamp bead 5, so that when the knob 12 is rotated, the lamp bead 5 will be stably driven to rotate, improving the flexibility of light effect adjustment.

[0029] Example 2: Figure 2 , Figure 4 and Figure 6 The technical solution shown addresses the problem that the lens 6 is inconvenient to replace and adjust for different light effects during use. This adjustable LED lighting device discloses a disassembly and assembly mechanism. A lens 6 is positioned below the LED bead 5, and disassembly and assembly mechanisms for installing the lens 6 are provided on both the left and right sides. The disassembly and assembly mechanism includes a limiting frame 7, which is fixedly connected to the left and right sides of the lens 6. A locking block 9 is engaged on the side of the limiting frame 7, and a slot 10 matching the locking block 9 is provided on the inner side of the lamp housing 1. Connecting springs 11 are provided at both the front and rear ends of the locking block 9, and the locking block 9 and the lamp housing 1 form an elastic structure through the connecting springs 11.

[0030] In this example, such as Figure 6 As shown, lens 6 is positioned below lamp bead 5 and is attached to lamp housing 1 by limiting bracket 7. When other lighting effects are needed, various lighting effects can be adjusted by disassembling and replacing lens 6. Pull the locking block 9 to the side to separate the locking block 9 from the locking slot 10, and then remove lens 6 from inside lamp housing 1. When replacing different lenses 6, pull the locking block 9 to the inside of lamp housing 1 to fix the position of lens 6. After removing the pulling force applied to the locking block 9, the locking block 9 will be reset by the elastic force of connecting spring 11 and engage with locking slot 10, thereby realizing the installation and fixation of lens 6.

[0031] Example 3: Figure 1 , Figure 2 and Figure 4 The technical solution shown addresses the issue of high temperatures that may occur when using LED lights, necessitating the use of heat sinks 19 for heat dissipation. However, the heat sinks 19 may attract dust due to static electricity during prolonged heat dissipation. This adjustable-efficiency LED lighting device discloses an auxiliary heat dissipation mechanism. Heat sinks 19 are located at both the front and rear ends of the top of the lamp housing 1, and an auxiliary heat dissipation mechanism for cleaning the heat sinks 19 is located above them. The auxiliary heat dissipation mechanism includes a fixed frame 16, with a threaded rod 17 rotatably connected to one end of the fixed frame 16. A movable block 18 is threadedly connected to the outer side of the threaded rod 17, and a cleaning brush 20 matching the heat sink 19 is installed at the bottom of the movable block 18. A slider 8 is fixedly connected to the top of the movable block 18, and the slider 8 is slidably connected to the fixed frame 16.

[0032] In this example, such as Figure 2 As shown, the heat sink 19 assists in heat dissipation of the LED lamp body. However, the heat sink 19 is prone to attracting dust due to static electricity during heat dissipation, which weakens its heat dissipation performance during subsequent use. Therefore, by rotating the handle, the threaded rod 17 is rotated. The threaded rod 17 is threadedly connected to the movable block 18, allowing the threaded rod 17 to rotate and move the movable block 18. Simultaneously, the movable block 18 rotates the cleaning brush 20, which cleans the outer side of the heat sink 19, reducing dust residue and effectively preventing the heat sink 19 from weakening its heat dissipation performance due to dust accumulation. During movement, the movable block 18 causes the slider 8 to slide inside the fixed frame 16, thus limiting the angle of movement and preventing the movable block 18 from deflecting due to the rotation of the threaded rod 17.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
