[0002] A ceiling light is a type of lighting fixture, and as the name suggests, the top of the fixture is relatively flat, and when installed, the bottom is completely attached to the flat surface of the roof, hence the name. Compared to other high-spec lighting fixtures such as chandeliers, ceiling lights are relatively inexpensive and have a simple structure, and they can be seen everywhere in ordinary corridors and rooms.

[0003] When installing a ceiling lamp, it is common to leave a mounting box on the mounting surface in advance, and a locking device is installed inside the mounting box to connect it to the lamp fixture. This type of installation structure does not require driving expansion screws into the mounting surface, simplifying the installation steps and improving installation efficiency. However, this method requires a corresponding locking seat (mounting device) on the lamp body to engage with the locking device, and because the locking seat is an independent module, there is a relatively large fitting gap between the lamp body and the locking seat, which causes a decrease in the sealing performance of the lamp body.

[0022] 1 to 7, an easy-to-install lamp provided by the present invention will be described. In one embodiment, the easy-to-install lamp provided by the present invention includes a lampshade 1, a driving device 3, a light source assembly 4, a base plate 5, and a fastening member 6. The lampshade 1 is connected to the base plate 5. The base plate 5 and the lampshade 1 surround a receiving chamber, and the light source assembly 4 and the driving device 3 are installed within the receiving chamber. The fastening member 6 is also installed within the receiving chamber and connected to the base plate 5. A mounting hole is formed in the base plate 5. The fastening member 6 includes a fixing portion 601 and a fastening portion 602 that are angularly distributed. The fastening portion 602 extends outside the receiving chamber through a mounting hole opened in the base plate 5 so as to be fitted and engaged with a mounting box. The fixing portion 601 is connected to the base plate 5 and closes the mounting hole.

[0023] Compared to the prior art, the lamp provided in this embodiment is easy to install. The fastening member 6 is connected to the base plate 5, and the fastening portion 602 of the fastening member 6 passes through a mounting hole in the base plate 5, extends out of the housing chamber, and engages with the mounting box, realizing the connection between the base plate 5 and the mounting box. In this way, the connection with the mounting box can be achieved without the need for a separate mounting device, simplifying the structure and reducing production costs. In addition, the fixing portion 601 closes the mounting hole, ensuring the sealing of the housing chamber, preventing external foreign objects from entering the housing chamber, and extending the service life of the lamp.

[0024] Specifically, the driver 3 is electrically connected to the light source assembly 4 .

[0025] Alternatively, the fixing portion 601 may be screwed or fastened to the base plate 5 or glued.

[0026] The mounting box has a locking hole, and the engaging portion 602 engages with the locking hole to realize the connection between the base plate 5 and the mounting box.

[0027] In some embodiments, referring to FIG. 7, the base plate 5 is provided with a plurality of stop sheets 501, which surround and form stop grooves that fit the fixing portions 601, and the fixing portions 601 are provided within the stop grooves.

[0028] The fixing portion 601 is provided in the stop groove, and the stop sheet 501 can restrict the position of the fixing portion 601, thereby improving the stability and reliability of the connection between the fixing portion 601 and the base plate 5. Furthermore, the stop sheet 501 can be used to position the fixing portion 601 during installation, thereby improving installation efficiency. Multiple stop sheets 501 may be provided at intervals to facilitate insertion and removal of the fixing portion 601.

[0029] In some embodiments, referring to FIGS. 1, 3, and 5, the base plate 5 further includes a locking hole and a relief hole. The easy-to-install lamp further includes a locking assembly 7 disposed within the housing chamber, the locking assembly 7 including a locking block 701, an elastic member 702, and a driving block 703. The locking block 701 is disposed within the housing chamber. The locking block 701 has a locking portion 7011 extending through the locking hole and out of the housing chamber, the locking portion 7011 being used for insertion and mating with the mounting box. As shown in FIG. 7, a locking groove 7012 is disposed on the side of the locking block 701 away from the locking portion 7011. The elastic member 702 is disposed within the locking groove 7012, and the elastic member 702 is configured to have a clamping force that holds the locking portion 7011 and the mounting box in place. The driving block 703 includes a driving part 7032 located in the accommodation chamber and a pressing part 7031 drilled in the relief hole, and the driving part 7032 is used to separate the locking part 7011 from the mounting box.

[0030] After the fastening portion 602 of the fastening member 6 is fastened to the mounting box, the locking portion 7011 of the locking block 701 passes through the locking hole and is inserted into the corresponding groove of the mounting box by the action of the elastic member 702, thereby locking the base plate 5 to the mounting box. When it is necessary to separate the base plate 5 from the mounting box, a force is applied to the pressing portion 7031 of the driving block 703, causing the driving portion 7032 to press the locking member, which then presses the elastic member 702, thereby separating the base plate 5 from the mounting box. In this embodiment, the elastic member 702 locks the locking portion 7011 to the mounting box, ensuring that the fastening member 6 and the mounting box remain engaged and improving the strength and reliability of the connection between the base plate 5 and the mounting box. Furthermore, the driving block 703 applies a force to the locking block 701 to separate the locking portion 7011 from the mounting box, thereby unlocking the fastening member 6 from the mounting box.

[0031] Optionally, the axes of the lock hole and the relief hole are parallel, and the driving part 7032 abuts or is connected to the lock block 701, so that when the pressing part 7031 is pulled, the lock block 701 moves in the opposite direction until the lock part 7011 and the mounting box are separated.

[0032] In some embodiments, referring to FIGS. 5 and 7, the lock block 701 is provided with an inclined guide surface, the driver 7032 has a connecting groove that fits the lock block 701, the lock block 701 is inserted into the connecting groove, and the driver 7032 abuts against the guide surface.

[0033] By biasing the pressing portion 7031, the driving portion 7032 can be moved toward the lock block 701, thereby causing the driving portion 7032 to press the lock block 701. Because a guide surface is provided, the driving portion 7032 can press the guide surface to move the lock block 701 away from the mounting box (pressing the elastic member 702 when the lock block 701 moves away from the mounting box), thereby realizing separation of the lock portion 7011 and the mounting box.

[0034] Optionally, the lock block 701 has a drive ramp that fits against the guide surface, and the drive ramp contacts the guide surface to reduce resistance when the driver 7032 pushes the lock block 701 to move in the reverse direction.

[0035] Specifically, the axis of the lock hole is perpendicular to the axis of the relief hole.

[0036] In some embodiments, referring to FIG. 5, the drive block 703 further includes a stop sheet 7033 connected to the drive portion 7032, and the stop sheet 7033 abuts against the base plate 5 and is used to position the drive portion 7032.

[0037] The stop sheet 7033 is positioned within the accommodation chamber and can abut against the base plate 5, thereby limiting the drive unit 7032 within the accommodation chamber and preventing the drive unit 7032 from moving out of the escape hole and causing the drive block 703 and the base plate 5 to separate.

[0038] In some embodiments, referring to Figures 1, 3 and 6, the easy-to-install lamp is arranged in a housing chamber and further includes a lens 2 connected to a base plate 5, and the lens 2 includes a light-reflecting area 202 and a light-transmitting area 201 arranged around the outer periphery of the light-reflecting area 202, and the light-transmitting area 201 is arranged corresponding to the light extraction side of the light source assembly 4.

[0039] The light emitted by the light source assembly 4 passes through the light-transmitting area 201 before being projected outward, which makes the light projected from the lampshade 1 softer and more uniform. The light-reflecting area 202 blocks the light from passing through, avoiding the problem of reduced brightness caused by light scattering.

[0040] Optionally, the light-transmitting area 201 can be made of a highly diffusive material or other surface treatment to improve the light extraction effect. The shielding area (i.e., the light-reflecting area) can be made of a transparent material to facilitate visual inspection and installation. The shielding area can be made of a highly reflective surface treatment to improve reflection efficiency and enhance the light extraction effect.

[0041] In some embodiments, referring to Figures 3 and 6, the lens 2 further includes a mounting bracket 203 connected to the outer peripheral surface of the light-transmitting area 201, and the mounting bracket 203 is connected to the base plate 5 and engages with the lampshade 1.

[0042] Because the diameter of the base plate 5 is relatively large, directly connecting the base plate 5 to the lampshade 1 not only requires a larger number of mounting members to ensure connection stability, but also makes the installation process relatively complicated. In this embodiment, the base plate 5 is connected to the lampshade 1 using mounting brackets 203, eliminating the need for mounting structures on the base plate 5 and simplifying the structure of the base plate 5. Furthermore, because the size of the lens 2 is smaller than that of the base plate 5, fewer mounting brackets 203 can be used, simplifying the installation process and reducing production costs.

[0043] Optionally, the mounting bracket 203 is screwed or hooked to the base plate 5 and the lampshade 1 respectively.

[0044] In some embodiments, referring to FIG. 4, the mounting bracket 203 includes a bracket body 2031 and a connection flange provided on the outer edge of the bracket body 2031, the bracket body 2031 being connected to the outer peripheral surface of the light-transmitting area 201 and also being connected to the base plate 5, and the connection flange being configured to abut against the lampshade 1 in the vertical direction.

[0045] After the bracket body 2031 is fixed to the base plate 5, the lampshade 1 is rotated until the connecting flange abuts against the mounting portion of the lampshade 1 in the vertical direction, thereby realizing the connection between the lampshade 1 and the mounting bracket 203. This embodiment has a simple structure, is easy to install, improves installation efficiency, and makes it easy to remove the lampshade 1 for subsequent maintenance of the lighting fixture.

[0046] 4, in some embodiments, a first mounting hole is formed in the bracket body 2031, a second mounting hole that matches the first mounting hole is formed in the base plate 5, and connecting members are inserted into the first and second mounting holes. The connecting flange includes a connecting portion 2032 and a stop portion 2033 that are angled, the connecting portion 2032 is used to abut against the lampshade 1 in the vertical direction, and the stop portion 2033 is used to position the lampshade 1 in the circumferential direction.

[0047] After aligning the first and second mounting holes, the connecting member is inserted into the first and second mounting holes to connect the bracket body 2031 to the base plate 5. Then, the lampshade 1 is rotated until the connecting portion 2032 of the connecting flange abuts against the mounting portion of the lampshade 1, and the stop portion 2033 blocks the lampshade 1 in the circumferential direction, preventing the lampshade 1 from rotating any further. At this point, the lampshade 1 is connected to the mounting bracket 203. The stop portion 2033 prevents the lampshade 1 from being separated from the connecting portion 2032 due to the lampshade 1 rotating at an excessively large angle.

[0048] Optionally, the connecting member is a threaded member or a fastening member 6 .

[0049] In some embodiments, referring to FIG. 4, the lampshade 1 has a mounting portion that abuts and fits with the mounting bracket 203, and the easy-to-install lamp fixture further includes an elastic locking sheet 8 connected to the mounting bracket 203, the elastic locking sheet 8 and the stop portion 2033 are circumferentially spaced apart, and the mounting portion of the lampshade 1 is located between the elastic locking sheet 8 and the stop portion 2033.

[0050] When the lampshade 1 is connected to the mounting bracket 203, the mounting portion of the lampshade 1 presses the elastic locking sheet 8, and after the elastic locking sheet 8 is deformed to a certain extent under the force, the mounting portion of the lampshade 1 separates from the elastic locking sheet 8 and enters the space between the elastic locking sheet 8 and the stop portion 2033. After separating from the mounting portion, the elastic locking sheet 8 returns to its original state due to its own elasticity and can regulate the position of the mounting portion of the lampshade 1 in the circumferential direction. In this embodiment, the elastic locking sheet 8 and the stop portion 2033 regulate the position on opposite sides of the mounting portion, respectively, improving the stability and reliability of the connection between the lampshade 1 and the mounting bracket 203.

[0051] There is no limit to the number of mounting brackets 203 provided with the elastic locking sheet 8. Optionally, at least one mounting bracket 203 is connected with the elastic locking sheet 8.

[0052] Optionally, the elastic locking sheet 8 is screwed or fastened to the mounting bracket 203 .

[0053] The above are only preferred embodiments of the present invention, and do not limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
