Technical Field

[0001] This utility model relates to the field of dot matrix light technology, specifically a magnetic dot matrix light. Background Technology

[0002] LED dot matrix lights, as an important component of modern lighting and display technology, have attracted widespread attention for their unique visual effects and wide range of applications.

[0003] However, some problems still exist in existing dot matrix lights:

[0004] (1) Due to factors such as the arrangement of LED beads, the design of the light guide plate, and the use of reflective materials, uneven light scattering is often caused. This not only affects the lighting effect, but may also cause visual fatigue and light pollution, especially in lighting occasions that require high brightness and high uniformity.

[0005] (2) Traditional LED dot matrix lights usually do not have sound sensing function and cannot automatically adjust the lighting status according to changes in ambient sound. The lack of sound sensing function makes it impossible for LED dot matrix lights to be linked with sound signals, thus failing to create richer and more varied visual effects.

[0006] (3) LED dot matrix lights typically use traditional wiring methods, that is, connecting the light fixture to the power supply through wires. This method is not only cumbersome to install, but also poses safety hazards. Especially in situations where the light fixtures need to be frequently replaced or moved, the traditional wiring method obviously cannot meet the requirements. Utility Model Content

The grid plate has multiple holes, and multiple LEDs are connected to the circuit board. The number and position of the LEDs correspond to the number of holes. The diffusion film covers all holes and diffuses the light emitted by the LEDs. A controller for controlling all the LEDs is soldered onto the circuit board. The housing has a sound sensor connected to the circuit board for sound detection. Two magnetic female connectors are mounted at the bottom of the housing, and these connectors are connected to the circuit board for magnetic connection.

[0010] Furthermore, the circuit board is fixed to the bottom of the cavity, and a charging port electrically connected to the circuit board is installed on one side of the outer shell.

[0011] Furthermore, the grid plate is fixed tightly against the inner wall of the cavity, and the inner wall of the cavity is provided with protrusions for fixing the grid plate with barbs, and the grid plate has grooves corresponding to the number and position of the barbs.

[0012] Furthermore, the grid plate surface is provided with a diffusion film mounting groove for mounting the diffusion film, so that the horizontal plane where the diffusion film is located is aligned with the grid plate.

[0013] Furthermore, a sound sensor mounting slot is provided on one side of the housing for mounting a sound sensor, and the sound sensor passes through the housing and connects to the circuit board.

[0014] Furthermore, the top of the outer casing is provided with a nameplate mounting groove for mounting a nameplate, and the bottom of the nameplate is provided with a downward protruding insertion rod that is fixed inside the grid plate. The grid plate has slots corresponding to the number and position of the insertion rods.

Detailed Implementation

[0023] 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.

[0024] like Figure 1-4 As shown, this utility model provides a magnetic dot matrix lamp, including a housing 1 and a nameplate 2. The nameplate 2 is connected to the top opening of the housing 1, forming a sealed cavity inside the housing 1. A circuit board 3 is installed at the bottom of the cavity, and multiple LEDs 7 for illumination are connected to the circuit board 3, so that the light from the LEDs 7 shines on the nameplate 2. At this time, in order to form the structure of the dot matrix lamp, the LEDs 7 are distributed in a matrix structure.

[0025] To improve the light guiding effect of LED lamp 7 and to make the light scattering of LED lamp 7 more uniform, a grid plate 4 and a diffusion film 5 are added to the cavity 1. Multiple holes 6 are set in the grid plate 4, and the position of each hole 6 corresponds one-to-one with the LED lamp 7. The use of the grid plate 4 helps to make the light from LED lamp 7 softer and more uniform, avoiding the generation of glaring light spots, providing a warm and comfortable atmosphere for the indoor environment, and improving the lighting quality. The diffusion film 5, during installation, covers all the holes 6 of the grid plate 4, mainly used to evenly diffuse the light from LED lamp 7 to the back of the nameplate 2.

[0026] During installation, the nameplate 2, circuit board 3, grid plate 4, and diffusion film 5 are arranged as follows: circuit board 3 is fixed to the bottom of the cavity, grid plate 4 is positioned above circuit board 3, and diffusion film 5 is positioned above grid plate 4. Grid plate 4 is fixed tightly against the inner wall of the cavity. The inner wall of the cavity has protrusions for fixing barbs 12 to the grid plate 4. Correspondingly, grid plate 4 has grooves 13 corresponding to the number and position of the barbs 12. When installing diffusion film 5, the surface of grid plate 4 has diffusion film mounting grooves 14 for installing diffusion film 5, aligning the horizontal plane of diffusion film 5 with grid plate 4. When installing nameplate 2, the top of the outer casing 1 has a nameplate mounting groove 16 for installing nameplate 2. Simultaneously, the bottom of nameplate 2 has downward-protruding insertion rods 17 for fixing inside grid plate 4. Correspondingly, grid plate 4 has slots 18 corresponding to the number and position of insertion rods 17, facilitating assembly and disassembly.

[0027] To further optimize the structure of the dot matrix light, a controller 8 for controlling all the LEDs 7 of the dot matrix light and a sound sensor 9 for detecting sound to create a sound-controlled effect are installed on the circuit board 3 by soldering. Based on the information from the sound sensor 9, the controller 8 can control the LEDs 7 to form different display modes. The sound controller 9 is located on one side of the housing 1, and a sound sensor mounting slot 15 is opened on the side of the housing 1 for mounting the sound sensor 9. At this time, the sound sensor 9 passes through the housing 1 and connects to the circuit board 3.

[0028] To achieve power supply for the dot matrix lights, different methods can be used. Firstly, two magnetic connectors 10 are located at the bottom of the housing 1. These connectors connect to the circuit board 3 via magnetic attachment, enabling convenient and quick connection to a power source. Secondly, a charging port 11, electrically connected to the circuit board 3, is installed on one side of the housing 1. Users can insert a charging cable of the corresponding type into the charging port 11 for charging. These two different charging methods overcome the limitations imposed by limited installation space.

[0029] Compared with traditional technologies, this technical solution adds the structure of grid plate 4 and diffusion film 5, optimizes the light guide setting of LED lamp 7, so that the light of LED lamp 4 is more evenly distributed to the entire lighting area, improving the utilization rate and uniformity of light; the sound sensor 9 enables the lamp to automatically adjust the lighting state according to the changes in ambient sound, thereby creating richer visual effects; the introduction of magnetic female connector 10 for power connection makes it easier and faster for the lamp to be connected to the power supply.
