Description

Technical Field

[0001] The utility model relates to the technical field of downlights, in particular to a surface cover structure of a downlight. Background Art

[0002] Downlights are a type of lighting fixture that is embedded in the ceiling and radiates light downward. Downlights have the advantages of not taking up space, being elegant in appearance, durable, and inexpensive. More and more people are using downlights as indoor lighting fixtures, and existing downlights include a lamp body and a face ring. Generally, the lamp body of a downlight is embedded and installed, while the face ring is exposed on the surface. The connection between the face ring and the lamp body mainly adopts a snap-on method. During installation, the face ring must be installed after the lamp body is installed. In addition, the buckles of the face ring need to be aligned with the corresponding installation positions of the lamp body. The buckles generally include multiple buckles. To install the face ring, each buckle needs to be snapped into the lamp body at the same time. Such a structure is very inconvenient. It is difficult for people to install and remove the face ring on a ladder, which is not conducive to people's later maintenance. Moreover, downlights now have no safety structure. If electrical components such as the light source panel of the downlight are damaged and need to be repaired, people can only disconnect the power switch for repair first, which will affect the use of other electrical appliances during the repair process and pose a safety hazard.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] As shown in the accompanying drawings, the utility model provides a face cover structure of a downlight, comprising a lamp body device 1 and a face cover 2, wherein the lamp body device 1 comprises a lamp housing 3 and a light source board 4, a plurality of magnetic blocks 5 are arranged in a ring on the front side of the lamp housing 3, a metal plate 6 is fixed to the rear side of the face cover 2, the magnetic blocks 5 are adsorbed and connected to the metal plate 6, a light-transmitting portion 20 is provided in the middle of the face cover 2, the light source board 4 is fixed to the inner side of the lamp housing 3 and is connected to a power source 40, a power-off switch 7 is connected between the light source board 4 and the power source 40, and a converter is also included.

[0020] The utility model discloses a surface cover structure of a downlight, and its principle and effect. Through the arrangement of the surface cover 2 and the lamp body device 1, the lamp housing 3 is adsorbed on the metal plate 6 of the surface cover 2 by the arranged magnetic suction block 5 to achieve the fixed connection between the lamp body device 1 and the surface cover 2. At the same time, the magnetic suction block 5 can be adsorbed on any position of the metal plate 6, thereby replacing the traditional clamping method. A plurality of magnetic suction blocks 5 are arranged, and are distributed in an annular manner on the side of the lamp housing 3 facing the surface cover 2. At the same time, the surface cover 2 is light in weight. The surface cover 2 can also be fixed by using the adsorption method instead of the clamping method, which is convenient for installation and disassembly, and further convenient for the later downlight. For maintenance, one only needs to directly remove the bottom cover 2 to separate the magnetic block 5 from the metal plate 6 to complete the disassembly of the bottom cover 2. At the same time, a power-off protection function is provided by the power-off switch 7 arranged between the light source board 4 and the power supply 40. When performing maintenance, people only need to turn on the power-off switch 7 to disconnect the power supply of the light source board 4 without affecting the use of other electrical appliances, so that people can specifically disconnect the power supply of the downlight to be repaired. A power-off function is provided, so that even if people forget to turn off the power switch on the ladder, the power supply of the downlight can be disconnected by the power-off switch 7, which can prevent people from repairing in the power-on state and reduce safety hazards.

[0021] In this embodiment, the lamp housing 3 is as follows Figure 3As shown, it includes a mounting ring 31 and two sleeves 32 vertically arranged on the rear side of the panel, and the two sleeves 32 are arranged at intervals to form an annular groove 320. The lamp body device 1 includes a bottom plate 33 fixedly connected to the lamp housing 3, and a reflective sticker 44 is arranged on the front side of the bottom plate 33. This belongs to the existing structure. In the past, downlights mostly used reflective cups. The light source board 4 of the existing downlight is arranged in the middle of the lamp housing 3 and faces the light-transmitting cover. The reflective cup is installed on the inner wall of the lamp housing 3. The present downlight structure achieves the effect of avoiding direct light source by arranging the light source board 4 on the inner wall of the lamp housing 3 and arranging the reflective sticker 44 on the position of the original light source board 4. Because the light source board 4 of the existing downlight is installed on the front, the LED lamp beads on the light source board 4 will be more prominent when the light is on, and it can be seen from the outside. When you look at it, you can see bright spots emitted by the LED lamp beads, and the light is not uniform. Therefore, this downlight reduces the bright spots emitted by the LED lamp beads through the reverse setting, so that people can see the light of the downlight more uniformly from the outside. The power-off switch 7 is arranged in the ring groove 320 and protrudes to the front side of the mounting ring 31. The magnetic block 5 is arranged in a ring shape on the front side of the mounting ring 31. The mounting ring 31 is provided with a sunken opening 310 facing the power-off switch 7, that is, the power-off switch 7 and the magnetic block 5 are both arranged on the front side of the mounting ring 31, so that people can see them by removing the bottom cover 2, which is convenient for people to use the power-off switch 7. The mounting ring 31 is also provided with a mounting groove for fixing the magnetic block 5, so that the power-off switch 7 and the magnetic block 5 do not protrude from the mounting ring 31, so that the surface cover 2 and the lamp housing 3 are more closely installed.

[0022] In this embodiment, the cover 2 is as follows Figure 5 As shown, it is in a circular ring shape, and the inner and outer circular side walls of the face cover 2 are both protruding backwards and are provided with a surrounding edge 22, thereby forming a groove 200 corresponding to the mounting ring 31, and the metal plate 6 is arranged in the groove 200, and the light-transmitting portion 20 is placed at the inner circle. The light-transmitting portion 20 belongs to the existing structure and will not be described in detail here. It should be noted that the height of the surrounding edge 22 is equal to the thickness of the metal plate 6 and the mounting ring 31, so that the face cover 2 just covers the mounting ring 31, and the metal plate 6 is also in a circular ring shape and just corresponds to the groove 200.

[0023] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
