Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically to a ceiling light. Background Technology

[0002] A ceiling light is an electrical device that transmits, distributes, and alters the distribution of light. It is typically mounted on the ceiling or roof and generally includes a lamp holder, a light source installed within the holder, and a lampshade covering the bottom of the holder. Traditional ceiling lights connect the lamp housing and lampshade with screws. While this screw connection ensures a secure connection, it is extremely inconvenient to install and remove, requiring a significant amount of time and effort.

[0003] To facilitate maintenance, Chinese patent application CN202421289312.4, entitled "A Ceiling Light with Simple Installation," features a U-shaped bracket on the lamp housing, along with an n-shaped hook on the lampshade. When the lampshade is large, the n-shaped hook is first hung on the U-shaped bracket before installing the lamp housing and internal light source board. After installation, the lampshade is simply rotated upwards around the crossbar of the U-shaped bracket, and then the edge of the lampshade is forcefully inserted into the mounting groove, allowing the positioning spring to engage in the positioning slot. This simple installation process improves ease of installation, stability, and prevents the lamp from falling, making it highly practical.

[0004] However, in the above solution, the light source is installed on the lamp holder. This means that when replacing the lamp board, performing maintenance, adjusting the color temperature, adjusting the power, etc., the operator needs to look up to operate, which is still relatively troublesome.

However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0046] like Figures 1 to 7 The image shows a preferred embodiment of the ceiling light of this utility model. The ceiling light includes a lamp holder 1, a lampshade 2, and a light source board 3.

[0047] The lamp holder 1 has an opening at its bottom for mounting on the bottom of a mounting surface. This mounting surface can be a ceiling or roof, and is generally flush with the horizontal plane, but can also be offset at a certain angle from the horizontal plane.

[0048] Specifically, two fixed lugs 11 are arranged at intervals on the outer wall of the rear side of the lamp holder 1. A shaft groove 111 extending in the left and right direction is opened on the opposite surface of the two fixed lugs 11. A notch 112 communicating with the corresponding shaft groove 111 is opened on the top side of one of the fixed lugs 11.

[0049] Fixing blocks 12 are provided on the outer walls of the front, left and right sides of the lamp holder 1;

[0050] A first connecting post 13 is provided on the outer wall of the front side of the lamp holder 1, and a first connecting hole 131 is provided through the first connecting post 13 in the vertical direction.

[0051] The lampshade 2 is placed over the bottom opening of the lamp holder 1, and a receiving cavity 10 is formed between the lampshade 2 and the lamp holder 1.

[0052] Specifically, the outer wall of the front side of the lampshade 2 is provided with an upwardly extending rotating seat 21. The end of the rotating seat 21 has a rotating shaft 211 extending in the left and right direction. The two ends of the rotating shaft 211 can be rotatably inserted into the two shaft grooves 111, thereby realizing the hinge of the rear side of the lampshade 2 to the rear side of the lamp holder 1. In addition, one end of the rotating shaft 211 can pass through the notch 112 and enter and exit the corresponding shaft groove 111, thereby facilitating the installation of the rotating shaft 211.

[0053] The lampshade 2 has upwardly extending elastic clips 22 on the outer walls of the front, left and right sides. Each elastic clip 22 corresponds to the aforementioned fixing block 12. The tail of each elastic clip 22 has a fastening part 221 that can be fastened to the corresponding fixing block 12, thereby realizing the snap-fit ​​connection of the front, left and right sides of the lampshade 2 to the front, left and right sides of the lamp holder 1.

[0054] A second connecting post 23 is provided on the outer wall of the front side of the lampshade 2. A second connecting hole 231 is provided through the second connecting post 23 in the vertical direction. The second connecting post 23 and the first connecting post 13 are connected to each other through the second connecting hole 231 and the first connecting hole 131 and are fixed by screws (not shown in the figure) as fasteners, thereby realizing the threaded connection of the front side of the lampshade 2 to the front side of the lamp holder 1.

[0055] The back of the lampshade 2 (i.e. the side facing the lamp holder 1) is provided with three connecting seats 24 arranged circumferentially. Each connecting seat 24 has an upwardly extending plug-in piece 241 at its end, and the top of the plug-in piece 241 is connected to a limit block 242.

[0056] The back of the lampshade 2 is also provided with a third connecting post 25 spaced apart from the connecting seat 24, and the third connecting post 25 is threaded with a vertically arranged bolt 251.

[0057] The light source board 3 is installed inside the aforementioned accommodating cavity 10.

[0058] Specifically, the periphery of the light source plate 3 has three first connecting pieces 31 arranged at intervals along its circumference. Each first connecting piece 31 corresponds to the connecting seat 24. Each first connecting piece 31 has a first arc-shaped hole 311 extending along its circumference. The first arc-shaped hole 311 includes a first wide portion 3111 and a first narrow portion 3112 arranged sequentially along its length. The plug-in piece 241 can slide through the first arc-shaped hole 311, and the limiting block 242 can only pass through the first arc-shaped hole 311 through the first wide portion 3111.

[0059] The periphery of the light source plate 3 also has a second connecting piece 32 spaced apart from the first connecting piece 31. The second connecting piece 32 has a second arc-shaped hole 321 extending in its circumference. The second arc-shaped hole 321 includes a second wide portion 3211 and a second narrow portion 3212 arranged sequentially along its length. The threaded portion of the bolt 251 can slide through the second arc-shaped hole 321, and the head of the bolt 251 can only pass through the second arc-shaped hole 321 through the second wide portion 3211.

[0060] With bolt 251 loosened, the light source plate 3 can rotate around its own axis between the locked and unlocked positions, thereby enabling the light source plate 3 to be locked and unlocked on the back of the lampshade 2.

[0061] When the light source board 3 is in the locked position, such as Figure 6 As shown, each limiting block 242 is directly opposite the first narrow portion 3112, and the head of the bolt 251 is directly opposite the second narrow portion 3212. In this way, the heads of each limiting block 242 and the bolt 251 are limited to the surface of the second connecting piece 32 corresponding to the first connecting piece 31, so that the light source plate 3 is limited to the lamp cover 2.

[0062] When the light source board 3 is in the unlocked position, such as Figure 7 As shown, each limiting block 242 is directly opposite the first wide portion 3111, and the head of the bolt 251 is directly opposite the second wide portion 3211. In this way, the heads of each limiting block 242 and the bolt 251 can pass through the corresponding first wide portion 3111 and second wide portion 3211 along the axial direction, so that the light source plate 3 can be separated from the lamp cover 2.

[0063] The working principle of this embodiment is as follows:

[0064] (1) In the initial state, such as Figure 1 , Figure 2 and Figure 4 As shown, the fastening part 221 of each elastic clip 22 is fastened to the corresponding fixing block 12. The second connecting post 23 and the first connecting post 13 are connected to each other through the second connecting hole 231 and the first connecting hole 131 and fixed by screws so that the lamp cover 2 is kept in the closed state.

[0065] (2) When it is necessary to open the lampshade 2, first unscrew the screws to disengage the second connecting post 23 from the first connecting post 13. Then, pull each elastic locking foot 22 outward to bend and deform it outward until each fastening part 221 disengages from the corresponding fixing block 12. The lampshade 2 flips downward under its own weight and remains in the open state. At this time, if Figure 5 and Figure 6 As shown, the lampshade 2 is in a vertically hanging state so that the light source board 3 is exposed in front of the operator, and the light source board 3 is in a locked position, which allows for operations such as replacing the light source board, maintenance, adjusting the color temperature, and adjusting the power.

[0066] If it is necessary to disassemble the light source board 3, first loosen bolt 251 to release the pressure of its head on the surface of the second connecting piece 32, and then rotate the light source board 3 from the locked position to the unlocked position. At this time, if Figure 7 As shown, the heads of each limiting block 242 and bolt 251 pass through the corresponding first width portion 3111 and second width portion 3211 along the axial direction. Therefore, the light source plate 3 can be disassembled by removing it along the axial direction.

[0067] (3) After the operation is completed, first insert the first wide portion 3111 and the second wide portion 3211 of the light source plate 3 into place, with the corresponding limit block 242 and bolt 251 heads facing each other. Then rotate the light source plate 3 from the unlocked position to the locked position. At this time, if Figure 5 and Figure 6 As shown, the heads of each limiting block 242 and bolt 251 are limited to the surface of the second connecting piece 32 corresponding to the first connecting piece 31. Finally, tightening the bolt 251 will realize the installation of the light source board 3.

[0068] Next, flip the lampshade 2 upwards. Under the pushing force of the fixing block 12, each elastic locking foot 22 will bend and deform outwards until each fastening part 221 passes over the fixing block 12. Then, screw the screws into the second connecting hole 231 and the first connecting hole 131. At this time, as... Figure 1 , Figure 2 and Figure 4 As shown, lampshade 2 returns to the off state.
