Technical Field

[0001] This utility model relates to the field of lighting devices, specifically an LED lighting device. Background Technology

[0002] Currently, LED lights are commonly installed on indoor ceilings as lighting devices. These lights are also known as ceiling lights. They mainly consist of an outer metal lampshade, LED strips and a driver installed inside the lampshade, and a light panel installed at the bottom of the lampshade. The LED strips are connected to each other and to the driver via terminals and connecting wires, and multiple LED strips are connected in series.

[0003] In use, because multiple light strips are connected in series, if the LED beads in one light strip fail, the entire light fixture will not light up. When replacing them, users usually replace only one light strip. However, the gap between the light strip and the lampshade is small, obstructing the view and making it impossible to see the terminal connection. Furthermore, the small size of the connection terminals makes it difficult to connect the light strip terminals. It is necessary to remove all the light strips and the driver power supply and install them on the ground, which is very inconvenient. Therefore, an LED lighting device is proposed to address the above problems. Utility Model Content

[0022] 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 scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] Please see Figure 1-4 As shown, an LED lighting device includes a lampshade 11, a light strip 14, a driver power supply 13, and a lamp board 12. The driver power supply 13 is installed inside the lampshade 11, and the lamp board 12 is installed at the bottom of the lampshade 11. It also includes multiple sliding seats 15, which are bolted to the inner top wall of the lampshade 11. A slider 17 is slidably connected inside each sliding seat 15, and a fixing seat 16 is fixedly connected to the side of each slider 17. The light strip 14 is detachably mounted on the fixing seat 16, which has multiple mounting holes. In use, the light strip 14 is fixed to the fixing seat 16 with screws. The mounting holes are used to engage with the screws for fixation. When a single light strip 14 needs to be replaced, the user can push the fixing seat 16, causing the slider 17 to slide within a groove, thus moving the light strip 14 to one side and increasing the space on the other side. This increases the operating space and facilitates the connection of terminals, making it easier for workers to connect terminals and for users to replace the light strip 14.

[0025] Furthermore, such as Figure 4As shown, springs 2 are fixed to the inner walls of both ends of the sliding seat 15, and the ends of the two springs 2 are fixed to the side walls of the slider 17. In use, by relying on the springs 2, the springs 2 can support the slider 17 from both sides, thus driving the fixed seat 16 and the lamp strip 14 to automatically reset, and limiting the position of the lamp strip 14 so that it is kept at the center position of the lamp cover 11.

[0026] Furthermore, such as Figure 3-4 As shown, a heat dissipation cavity 31 is provided in the middle of the fixing base 16, and a heat dissipation fin seat 32 is fixedly connected to the side wall of the heat dissipation cavity 31; a silicone grease pad 4 is provided on the side of the fixing base 16 near the lamp strip 14, and the silicone grease pad 4 is located between the fixing base 16 and the lamp strip 14; in this embodiment, a hollow heat dissipation cavity 31 is provided inside the fixing base 16, and then the heat dissipation fin seat 32 is attached to the inner side wall of the heat dissipation cavity 31, which can increase the contact area with air, thereby improving the heat dissipation effect of the lamp strip 14. Furthermore, a silicone grease pad 4 is provided on the side of the fixing base 16, which can improve the fit and facilitate heat conduction between the lamp strip 14 and the fixing base 16.

[0027] Furthermore, such as Figure 3 As shown, both ends of the side of the fixed base 16 are fixed with spring pieces, and the ends of the spring pieces are fixed with fixing clips 51. The fixing clips 51 have a protrusion 53 on the side end near the sliding base 15. The two ends of the side of the sliding base 15 have slots 52 at the positions corresponding to the protrusions 53. In this embodiment, the side of the fixed base 16 is also connected to the fixing clips 51 by spring pieces. When the fixed base 16 is pushed, its fixing frame bends under the action of the spring pieces, and then the protrusions 53 on the fixing frame are inserted into the slots 52, thereby moving the fixed base 16. This makes it convenient for workers to install and connect terminals. The fixing clips 51 are pressed to release the fixing of the slots 52.

[0028] Furthermore, such as Figure 5-6 As shown, a retainer 61 is fixedly connected to the side of the mounting hole. The retainer 61 passes through the mounting hole and has multiple through slots 62. The retainer 61 is made of plastic. A compression groove is formed at the end of the retainer 61. A ball bearing 63 is provided inside the compression groove. An elastic rope 64 is fixed between the ball bearing 63 and the inner wall of the retainer 61. In this embodiment, the retainer 61 is made of elastic plastic. In the initial state, the end of the retainer 61 is folded together so that the hole on the light strip 14 can pass through. Then, the ball bearing 63 is released, and the elastic rope 64 pulls the ball bearing 63 into the compression groove, thereby opening the end of the retainer 61 and clamping it to the light strip 14.

[0029] Furthermore, such as Figure 5-6As shown, the end of the card holder 61 is tapered. In use, the tapered end of the card holder 61 allows it to pass through the holes on the light strip 14, thus facilitating installation.

[0030] Working principle: During use, the light strip 14 is fixed to the mounting base 16 with screws. The mounting holes are used to engage with the screws for fixation. When it is necessary to replace a single light strip 14, the user can push the mounting base 16, and the slider 17 slides in the groove, thereby moving the light strip 14 to one side, increasing the space on the other side. This increases the operating space and facilitates the connection of the terminal, making it easier for the operator to connect the terminal and replace the light strip 14. A spring 2 supports the slider 17 from both sides, causing the mounting base 16 and the light strip 14 to automatically reset and restrict the position of the light strip 14, keeping it in the center of the lamp cover 11. The mounting base 16 has a hollow heat dissipation cavity 31 inside, and the heat dissipation fin seat 32 is attached to the inner wall of the heat dissipation cavity 31, thereby increasing the... The air contact area is increased to improve the heat dissipation effect of the light strip 14. Furthermore, the side of the fixing seat 16 is provided with a silicone grease pad 4, which can improve the fit and facilitate heat conduction between the light strip 14 and the fixing seat 16. The side of the fixing seat 16 is also connected to a fixing clip 51 by a spring. When the fixing seat 16 is pushed, its fixing frame bends under the action of the spring, and then the protrusion 53 on the fixing frame is inserted into the slot 52, thereby moving the fixing seat 16. This facilitates the installation and connection of the terminals by the staff. The fixing clip 51 is pressed to release the fixing of the slot 52. The card holder 61 is made of elastic plastic material. In the initial state, the end of the card holder 61 is folded together to allow the hole on the light strip 14 to pass through. Then the ball 63 is released, and the elastic rope 64 pulls the ball 63 into the inside of the compression groove, thereby opening the end of the card holder 61 and clamping it to the light strip 14.
