[0038] In this application, unless otherwise clearly specified and defined, terms such as "installed", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection, or capable of communicating with each other; it can be directly connected, or indirectly connected through an intermediate medium, which can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] See Figures 1 to 2 , an embodiment of this application provides a ceiling lamp. The ceiling lamp includes a lamp housing, which is formed by snapping together a chassis 100 and a lampshade 200. The chassis 100 is provided with a clamping member 151, and the lampshade 200 is provided with a clamping groove 201 that is snap-fitted with the clamping member 151. The chassis 100 is used to be fixed to the surface of a building such as a ceiling, and a light-emitting module 300 that is fixed in cooperation with the chassis 100 is provided inside the lamp housing.

[0040] See Figures 3 to 7 , the light-emitting module 300 includes a lamp board 310 and a base 320 for fixing the lamp board 310. The base 320 is provided with a card slot 330 extending circumferentially. The chassis 100 is provided with a clamping member 110 that cooperates with the card slot 330. Anti-withdrawal portions 331 and elastic portions 332 are respectively provided on two opposite sides of the card slot 330. When the clamping member 110 reaches the anti-withdrawal portion 331, the elastic portion 332 stores energy. When the clamping member 110 crosses the anti-withdrawal portion 331, the elastic portion 332 releases the stored energy to restrict the clamping member 110 from disengaging. Specifically, the anti-withdrawal portion 331 is a clamping protrusion 333 provided on one side of the card slot 330. The elastic portion 332 is a spring piece 334 fixed on the other side of the card slot 330. One end of the spring piece 334 is fixed, and the other end extends suspendedly along the path of the card slot 330, and the suspended position is directly opposite to the clamping protrusion 333.

[0041] In this embodiment, the light-emitting module of the ceiling lamp is replaceable. When installing the light-emitting module 300, the card slot 330 of the base 320 can be fitted to the engaging part 110 of the chassis 100. During installation, the engaging part 110 extends into the card slot 330 along the extension path of the card slot 330 until it reaches the anti-withdrawal part 331. When the engaging part 110 reaches the anti-withdrawal part 331, the engaging part 110 abuts against the elastic part 332, causing the elastic part 332 to deform, and the engaging part 110 continues to penetrate deeper into the card slot 330. After the engaging part 110 passes over the anti-withdrawal part 331, the elastic part 332 releases its force and returns to cooperate with the anti-withdrawal part 331 to restrict the engaging part 110 from coming out, thus achieving a good snap-fit fixation.

[0042] In addition, during the process of the engaging part 110 passing over the anti-withdrawal part 331, the engaging part 110 first moves towards the elastic part 332 in a direction perpendicular to the extension path of the card slot 330, and then is pushed back by the elastic part 332 in a direction perpendicular to the extension path of the card slot 330. At the moment of being pushed back, the engaging part 110 impacts with one side of the card slot 330, generating a clicking sound, indicating that the snap-fit is in place.

[0043] See Figure 9 , due to the increasing demand of consumers for personalized lighting, they hope to be able to change parameters such as the color, brightness, and color temperature of the ceiling lamp in a simple way. In some embodiments, the ceiling lamp includes a driving power module 400 fixedly fitted to the chassis 100, and the driving power module 400 is provided with a magnetic part magnetically fitted to the chassis 100. The driving power module 400 also has a through-hole 402 through which a fastener can be passed to be fixed to the chassis 100. The driving power module 400 is provided with a knob 403 for adjusting the color temperature and / or power. Since the driving power module 400 can adjust the color temperature and power through the knob 403, the required power and color temperature of consumers can be adjusted during the installation of the driving power module 400.

[0044] Most traditional ceiling lamp replacement modules are integrated modules of light source and driver. In actual applications, the entire integrated module needs to be replaced. For example, when the light source is normal but the driver is damaged, or when the light source is damaged but the driver is normal, the entire integrated module needs to be replaced, resulting in a relatively high replacement cost. In this embodiment, the light-emitting module 300 and the driving power module 400 are independent modules from each other. When the light source module is damaged or the driving power module 400 is damaged, the corresponding module can be replaced separately, greatly saving the replacement cost.

[0045] The increasing awareness of environmental protection also prompts people to seek more energy-efficient and environmentally friendly lighting solutions. The ceiling lamp provided in this embodiment allows the replacement of the driving power module 400 and the light-emitting module 300, which has significant advantages in improving energy efficiency and helps to reduce energy consumption. At the same time, the progress of manufacturing technology makes the production of ceiling lamp replacement modules more efficient and the cost gradually decreases, thus improving its market feasibility and popularity.

[0046] In addition, the driving power supply can be provided with a microwave sensor for sensing the movement of objects in space. The driving power supply module 400 and the light-emitting module 300 are respectively provided with quick wiring terminals 404 for realizing electrical connection with each other, including male and female ends of quick circuit connectors that are adapted to each other. The above-mentioned quick wiring terminals 404, microwave sensor, and knob 403 are all arranged on the same circuit board within the driving power supply module, greatly reducing the volume of the entire driving power supply module 400, and correspondingly reducing the volume of the plastic housing used for the driving power supply module 400.

[0047] See Figure 3 and Figures 5 to 8 , in some embodiments, the base 320 has support columns 321 that raise the light-emitting module 300 based on the chassis 100. The support columns 321 are hollow columns, and the support columns 321 are used to install fasteners or magnetic parts 322 for fixedly adsorbing to the chassis 100. The support columns 321 of this embodiment can be used for magnetic fixation or for fixing the light-emitting module 300 by passing fasteners through, thereby providing multiple compatible installation methods. The first installation method: using fasteners such as screws to pass through and fix the base 320 of the light-emitting module 300 to the chassis 100; the second installation method: using the magnetic part 322 to adsorb and fix the base 320 of the light-emitting module 300 to the chassis 100, at this time the chassis 100 is made of iron or the chassis 100 is provided with a magnet that cooperates with the magnetic part 322; the third installation method: using the snap-fit cooperation between the card slot 330 of the base 320 and the engaging part 110 of the chassis 100.

[0048] See Figures 5 to 8 , in some embodiments, the base 320 of the light-emitting module 300 is provided with hot melt columns 325, and the lamp board 310 is provided with through holes 311 that are adapted to the hot melt columns 325. The hot melt columns 325 pass through the through holes 311, and after the ends of the hot melt columns 325 are melted and solidified, an enlarged diameter part is formed to fix the lamp board 310. A positioning groove 323 adapted to the lamp board 310 is arranged on the base 320, and the bottom of the positioning groove 323 is provided with hot melt columns 325 and light-emitting holes 324. The positioning groove 323 on the base 320 is of an annular structure, and the lamp board 310 is of an arc structure and is composed of multiple pieces, which are sequentially spliced to form an annular shape. The lamp board 310 includes an aluminum substrate 314 and LED lamp beads 315 arranged on the aluminum substrate, and the LED lamp beads are adapted to the light-emitting holes 324. A pre-positioning member 312 is arranged between adjacent lamp boards 310, and the pre-positioning member 312 has a blocking part 313 that restricts the lamp board 310 from slipping out of the positioning groove 323. In this embodiment, the lamp board 310 is fixed to the base 320 by using the hot melt columns 325, which is firmly fixed and simplifies the installation process.

[0049] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification. When the technical features in different embodiments are embodied in the same drawing, the drawing can be regarded as also disclosing the combination examples of the respective embodiments involved.

[0050] The above-described embodiments merely represent several implementation manners of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application.
