Abstract
Description
Technical Field
[0001] This utility model belongs to the field of LED ceiling light technology, specifically relating to a radar-sensing LED emergency ceiling light. Background Technology
[0002] The radar-sensor LED emergency ceiling light uses a self-developed planar antenna transmitting and receiving circuit to intelligently detect the surrounding electromagnetic environment and automatically adjust its working status. Once the light is activated, it will remain on for a delay period if human activity is detected, continuing until the person leaves and the delay continues. Furthermore, it can control the light's operation based on ambient light intensity to achieve energy savings.
[0003] For example, in the Chinese utility model patent application CN212481021U entitled "A Dustproof LED Ceiling Light," although a dust filter is placed near the heat dissipation holes of the LED ceiling light to improve its dustproof effect while ensuring heat dissipation, and a dust filter is placed inside the light-transmitting cover to greatly reduce the contact between the internal electrical components of the LED ceiling light and external dust, in southern regions, during the humid season, water stains on the walls can affect the internal wiring of the LED ceiling light and shorten its lifespan.

The filter screen positions and supports the waterproof membrane.
[0007] As a further optimization of this utility model, a first magnet is fixedly connected to one side of the base. The first magnet is magnetically connected to the mounting base, and the base supports the first magnet.
[0008] As a further optimization of this utility model, a face ring is fixedly connected to the bottom end of the base by screws, and one side of the face ring is fixedly connected to one side of the dust cover, thereby fixing the position of the dust cover.
[0009] As a further optimization of this utility model, the filter screen is located inside the dust cover, and the position of the filter screen is positioned by the dust cover.
[0010] As a further optimization of this utility model, a number of heat dissipation plates are fixedly penetrated through the inner wall of the dust cover, and an electric wire passing through the mounting base is electrically connected to one side of the LED light, so that the position of the heat dissipation plates is fixed by the dust cover.
[0011] As a further optimization of this utility model, a second magnet is fixedly connected to one side of the filter screen. The second magnet is magnetically connected to the base, and the position of the second magnet is fixed by the filter screen.
[0012] The beneficial effects of this utility model are as follows: This utility model fixes the position of the base by the mounting bracket, fixes the position of the LED light and the face ring by the base, performs dust protection on the LED light by the cooperation of the face ring and the dust cover, avoids dust affecting the brightness of the LED light, filters the dust entering through the heat dissipation vent by the filter screen, and blocks water vapor by the waterproof membrane, preventing water vapor from damaging the internal circuit of the LED light and shortening the service life of the LED light.

Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0018] Example 1
[0019] like Figure 1 , Figure 2 and Figure 3As shown, a radar-sensing LED emergency ceiling light includes a mounting base 1 and a dust cover 13. A first magnet 3 is fixedly connected to the bottom of the mounting base 1. The mounting base 1 has multiple holes and is fixed to the wall by screws. The mounting base 1 is made of metal. A base 4 is provided at the bottom of the mounting base 1. The first magnet 3 is fixedly connected to one side of the base 4. The first magnet 3 is magnetically connected to the mounting base 1. The base 4 is made of metal and is attracted by the first magnet 3 to prevent the base 4 from being suspended. An LED light 12 is fixedly connected to the bottom of the base 4. One side of the LED light 12 is electrically connected to a through-hole. The wire 2 of the mounting base 1, together with other components, powers the LED light 12, facilitating its subsequent illumination. The bottom of the base 4 is fixedly connected to a face ring 5, which is secured by screws 8. The face ring 5 ensures that the light is distributed more evenly. The face ring 5 is made of PC material, which can effectively prevent the light from being too concentrated or causing glare, thus improving the lighting effect and comfort. One side of the face ring 5 is fixedly connected to one side of the dust cover 13, and the face ring 5 and the dust cover 13 are snapped together. The dust cover 13 blocks dust and flying insects, preventing dust or flying dust from adhering to the surface of the LED light 12.
[0020] like Figure 1 and Figure 3 As shown, several heat dissipation plates 6 are fixedly inserted through the inner wall of the dust cover 13. The front end of the heat dissipation plate 6 is arc-shaped, which absorbs heat and prevents the temperature inside the dust cover 13 from becoming too high. Several heat dissipation vents 7 are opened on the side wall of the dust cover 13, allowing air to circulate inside the dust cover 13 and cooling the interior. The filter screen 9 is attached to one side of the heat dissipation vent 7, and a second magnet 11 is fixedly connected to one side of the filter screen 9. The second magnet 11 is magnetically connected to the base 4, attracting the base 4 and fixing the position of the filter screen 9. The filter screen 9 blocks dust and flying insects flying in from the heat dissipation vent 7, preventing dust or flying insects from affecting the operation of the LED light 12. A waterproof membrane 10 is pasted on one side of the filter screen 9. The waterproof membrane 10, such as expanded polytetrafluoroethylene membrane, is a high-molecular breathable but waterproof material that maintains efficient gas exchange while being waterproof, preventing seal failure and promoting heat dissipation.
[0021] It should be noted that this radar-sensing LED emergency ceiling light is mounted on the wall using the mounting base 1. The mounting base 1 fixes the position of the first magnet 3, which in turn attracts the base 4. The base 4 supports the LED light 12. The LED light 12 can provide illumination through the cooperation of the wire 2 and other components. The dust cover 13 is fixed in position by the cooperation of the screw 8, the base 4, and the face ring 5. The dust cover 13 prevents dust from falling onto the LED light 12. The heat dissipation vent 7 provides initial heat dissipation inside the dust cover 13, and the heat dissipation plate 6 provides secondary heat dissipation. The filter 9 is fixed by the cooperation of the base 4 and the second magnet 11. The filter 9 prevents dust from entering the interior of the dust cover 13 through the heat dissipation vent 7. The filter 9 also fixes the waterproof membrane 10. If the filter 9 and the waterproof membrane 10 need to be replaced, the dust cover 13 can be opened.
[0022] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
