DOWNLIGHT WITH SCREW-FREE FIXATION STRUCTURE

BACKGROUND OF THE INVENTION
1. Field of the Invention

The present invention relates to a downlight, in particular to a downlight with screw-free fixation structure.

2. Description of the Prior Art

Currently available embedded downlights usually use screw locking or riveting to secure the light source board. These fixation methods usually require manual operation, which cannot be automated. These fixation methods not only increase the time and manpower costs in the production process but also incur a higher risk of human error. Additionally, the use of additional fixing components such as screws or rivets increases material costs. Therefore, these fixation methods result in increased production costs, reduced production efficiency, and may affect the overall quality and reliability of the product.

Furthermore, the currently available embedded downlights are installed in openings on the ceiling. However, the ceiling needs to be fixed with beams, hangers, joists, and other structures at the ceiling, causing some openings to potentially conflict with these structures. This situation renders currently available embedded downlights unable to be installed properly.

Moreover, the currently available embedded downlights are mostly of the vertical type, and the dip switch thereof are usually disposed on the driver. Due to the installation position of the driver, users are difficult to find out the dip switches. Thus, the currently available embedded downlights are inconvenient in use and cannot meet actual requirements.

The downlight with screw-free fixation structure in accordance with the embodiments of the present invention may have the following advantages:

(1) In one embodiment of the present invention, the downlight includes a lamp body and a light source board. The lamp body has a central hole, an inner ring body, and a plurality of protrusions. The inner ring body is disposed on the inner edge of the lamp body to partially cover the central hole. The protrusions are distributed along the inner edge of the lamp body and surrounding the central hole. A plurality of slots are formed respectively between the protrusions and the inner ring body. The light source board is disposed on the inner ring body and within the central hole, and engaged with the multiple slots. The light source board is disc-shaped. Via this screw-free fixation structural design, the downlight can securely fasten the light source board via a screw-free fixation mechanism, thereby reducing time and manpower costs in the production process and minimizing the risk of human error. Moreover, this screw-free fixation structural design eliminates the need for additional fixing components, thus reducing material costs. Consequently, the production cost of the downlight can be significantly reduced, and production efficiency enhanced.

(2) In one embodiment of the present invention, the light source board has a plurality of fixing holes, while one side of the light source board corresponding to the light source board is provided with a plurality of locking points. The locking points are inserted into the fixing holes. Via the slots, fixing holes, and locking points, a multifunctional fixing effect can be achieved, which not only achieves a snap-fit effect but also a press-fit effect. Therefore, this screw-free fixation structural design with multifunctional fixation effect can stabilize the light source board more effectively, enhancing the overall structural stability of the downlight.

(3) In one embodiment of the present invention, the downlight further includes a switch module and a control box. The switch module is disposed inside the control box, and the control box does not face the light-emitting surface of the light source board. Therefore, the control box and switch module do not affect the light-emitting effect of the light source board, and the user can conveniently operate the switch module to turn the downlight on or off, or adjust the brightness or color temperature thereof. As a result, the light emitting effect of the downlight can be effectively enhanced, and the downlight can be more convenient in use so as to provide the user with a great user experience.

(4) In one embodiment of the present invention, the light source board is disposed on the inner ring body within the central hole, with the inner ring body partially covering the light source board. Thus, one side of the light source board can partially protrude from the inner ring body, allowing the light source board to dissipate heat through the structure mentioned above, preventing damage due to overheating. This special heat dissipation structure design can effectively extend the service life of the downlight and enhance the reliability thereof.

(5) In one embodiment of the present invention, the shortest distance from the control box to the central axis of the lamp body's central hole is greater than half the radius of the lamp body's central hole. This side-mounted control box design creates a vacant space on one side of the control box. When the downlight is installed on the ceiling, this vacant space can accommodate beams or similar items to avoid interference with the structure of the building. Therefore, the downlight can be applied to various buildings, so the downlight can be more comprehensive in application and more flexible in use.

(6) In one embodiment of the present invention, the ultra-thin structural design of the downlight significantly reduces the thickness thereof, so it is convenient to install the downlight. Thus, the user can more easily install the downlight on various types of ceilings or walls, suitable for various buildings. At the same time, this structural design provides more possibilities for interior design to optimize the overall lighting effect. Therefore, the practicality of the downlight can be greatly enhanced.

FIG. 2 illustrates a perspective view of the downlight with screw-free fixation structure in accordance with one embodiment of the present invention. FIG. 3 is a top view of the downlight with screw-free fixation structure in accordance with one embodiment of the present invention. FIG. 4 is a schematic of a light source board and a lamp body of the downlight with screw-free fixation structure in accordance with one embodiment of the present invention. As shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4, the downlight 1 includes a lamp body 11, a light source board 12, a light cover 13, a control box 14, a switch module 15, two spring latches 16, and a power cable 17.

The lamp body 11 has a central hole 111, an inner ring body 112, four protrusions 113, and two holders 114. In this embodiment, the lamp body 11 can be made of non-metallic materials such as plastic. In another embodiment, the lamp body 11 can also be made of metal materials such as aluminum, copper, stainless steel, etc.

The inner ring body 112 is disposed on the inner edge of the lamp body 11 and partially covers the central hole 111. In this embodiment, the inner ring body 112 has a notch to accommodate the control box 14. One side of the inner ring body 112 has a plurality of locking points LP. In another embodiment, the inner ring body 112 can be a complete ring, and the control box 14 is disposed on the inner ring body 112.

The four protrusions 113 are distributed on the inner edge of the lamp body 11 and surround the central hole 111. The four protrusions 113 and the inner ring body 112 respectively form four slots. The number of protrusions 113 and slots can be adjusted according to actual needs.

The light source board 12 is disc-shaped. The light source board 12 is disposed on the inner ring body 112 and inside the central hole 111, and is mutually engaged with the four slots. The inner ring body 112 partially covers the light source board 12, such that one side of the light source board 12 is partially exposed from the inner ring body 112. The light source board 12 may have four straight sides 121 and two fixing holes 122. The two locking points LP are disposed on one side, corresponding to the light source board 12, of the inner ring body 112, and the two locking points LP are respectively inserted into the two fixing holes 122. In this embodiment, the number of straight sides 121 is equal to the number of slots. In another embodiment, the number of straight sides 121 is greater than the number of slots. In this embodiment, the number of fixing holes 122 is equal to the number of locking points LP. In another embodiment, the number of fixing holes 122 is greater than the number of locking points LP. The number of the above components can be adjusted according to actual needs.

The control box 14 is disposed on one side of the lamp body 11, and the switch module 15 is disposed inside the control box 14 and electrically connected to the light source board 12. The control box 14 also includes a power module and other necessary functional modules (not shown in the drawings), which are also electrically connected to the light source board 12. The switch module 15 can be used to turn the downlight 1 on or off, or adjust the brightness or color temperature of the downlight 1. In this embodiment, the switch module 15 can be a dip switch. In another embodiment, the switch module 15 can be a button, knob, or other similar component.

One end of the power cable 17 is connected to the control box 14, and the other end of the power cable 17 is connected to an external power source (such as mains electricity, generator, etc.).

The two holders 114 are disposed on one side of the lamp body 11, and two spring buckles 16 are respectively fixed on the two holders 114.

The light cover 13 is disposed on the other side of the lamp body 11 and covers the central hole 111 and the other side of the light source board 12. In one embodiment, the light cover 13 can be made of transparent or translucent materials, such as plastic, glass, etc.

As previous stated, the downlight 1 has a screw-free fixation structural design, so the light source board 12 can be fixed by a screw-free fixing mechanism, which can reduce the time and manpower costs in the production process and reduce the risk of human error. Furthermore, the screw-free fixation structural design does not require additional fixing components, thereby reducing material costs. Therefore, the production cost of the downlight 1 can be greatly reduced, and the production efficiency can be effectively improved.

In addition, through the above structure design, the control box 14 does not face the light-emitting surface of the light source board 12. Therefore, the control box 14 and the switch module 15 do not affect the light-emitting effect of the light source board 12, and the user can conveniently operate the switch module 15 to turn the downlight 1 on or off, or adjust the brightness or color temperature of the downlight 1. Therefore, the light-emitting effect of the downlight 1 can be effectively improved, so the downlight 1 can be more convenient in use in order to provide the user with a great user experience.

The embodiment just exemplifies the present invention and is not intended to limit the scope of the present invention; any equivalent modification and variation according to the spirit of the present invention is to be also included within the scope of the following claims and their equivalents.

Please refer to FIG. 5, which is a partial enlarged view of an inner ring body of the downlight with screw-free fixation structure in accordance with one embodiment of the present invention. As shown in FIG. 5, the inner ring body 112 has two plate bodies PB, and the two locking points LP are respectively disposed on the two plate bodies PB.

Please refer to FIG. 6, which is a schematic view of an assembling process of the downlight with screw-free fixation structure in accordance with one embodiment of the present invention. As shown in FIG. 6, the user can align the four straight sides 121 of the light source board 12 with the four protrusions 113 on the inner edge of the lamp body 11 and place the light source board 12 on the inner ring body 112. Then, the user can apply pressure towards the inner ring body 112 to press the light source board 12 to make the light source board 12 press the two locking points LP on the two plate bodies PB of the inner ring body 112. At this point, the two plate bodies PB pressed by the light source board 12 can provide resilience, causing the two locking points LP to be in an interference fit with the light source board 12. Subsequently, the user can rotate the light source board 12 to make the four slots GV of the lamp body 11 be engaged with the light source board 12. Finally, the user can stop rotating the light source board 12 when the two locking points LP are respectively inserted into the two fixing holes 112 of the light source board 12, and the structural strength of the plate bodies PB prevents the two locking points LP from disengaging from the two fixing holes 112 of the light source board 12. Consequently, the light source board 12 is engaged with the four slots GV of the lamp body 11, and the two locking points LP are respectively inserted into the two fixing holes 112 of the light source board 12.

Through the slots GV, fixing holes 112, and locking points LP described above, a multifunctional fixing effect can be achieved, which not only achieves a snap-fit effect but also a press-fit effect. Therefore, the screw-free fixation structural design with multifunctional fixing effect described above can more stably fix the light source board 12, thereby enhancing the overall structural stability of the downlight 1.

It is worthy to point out that currently available embedded downlights usually use screw locking or riveting to secure the light source board. These fixation methods usually require manual operation, which cannot be automated. These fixation methods not only increase the time and manpower costs in the production process but also incur a higher risk of human error. Additionally, the use of additional fixing components such as screws or rivets increases material costs. Therefore, these fixation methods result in increased production costs, reduced production efficiency, and may affect the overall quality and reliability of the product. Furthermore, the currently available embedded downlights are installed in openings on the ceiling. However, the ceiling needs to be fixed with beams, hangers, joists, and other structures at the ceiling, causing some openings to potentially conflict with these structures. This situation renders currently available embedded downlights unable to be installed properly. Moreover, the currently available embedded downlights are mostly of the vertical type, and the dip switch thereof are usually disposed on the driver. Due to the installation position of the driver, users are difficult to find out the dip switches. Thus, the currently available embedded downlights are inconvenient in use and cannot meet actual requirements. By contrast, according to one embodiment of the present invention, the downlight includes a lamp body and a light source board. The lamp body has a central hole, an inner ring body, and a plurality of protrusions. The inner ring body is disposed on the inner edge of the lamp body to partially cover the central hole. The protrusions are distributed along the inner edge of the lamp body and surrounding the central hole. A plurality of slots are formed respectively between the protrusions and the inner ring body. The light source board is disposed on the inner ring body and within the central hole, and engaged with the multiple slots. The light source board is disc-shaped. Via this screw-free fixation structural design, the downlight can securely fasten the light source board via a screw-free fixation mechanism, thereby reducing time and manpower costs in the production process and minimizing the risk of human error. Moreover, this screw-free fixation structural design eliminates the need for additional fixing components, thus reducing material costs. Consequently, the production cost of the downlight can be significantly reduced, and production efficiency enhanced.

According to one embodiment of the present invention, the light source board has a plurality of fixing holes, while one side of the light source board corresponding to the light source board is provided with a plurality of locking points. The locking points are inserted into the fixing holes. Via the slots, fixing holes, and locking points, a multifunctional fixing effect can be achieved, which not only achieves a snap-fit effect but also a press-fit effect. Therefore, this screw-free fixation structural design with multifunctional fixation effect can stabilize the light source board more effectively, enhancing the overall structural stability of the downlight.

Further, according to one embodiment of the present invention, the downlight further includes a switch module and a control box. The switch module is disposed inside the control box, and the control box does not face the light-emitting surface of the light source board. Therefore, the control box and switch module do not affect the light-emitting effect of the light source board, and the user can conveniently operate the switch module to turn the downlight on or off, or adjust the brightness or color temperature thereof. As a result, the light emitting effect of the downlight can be effectively enhanced, and the downlight can be more convenient in use so as to provide the user with a great user experience.

Moreover, according to one embodiment of the present invention, the light source board is disposed on the inner ring body within the central hole, with the inner ring body partially covering the light source board. Thus, one side of the light source board can partially protrude from the inner ring body, allowing the light source board to dissipate heat through the structure mentioned above, preventing damage due to overheating. This special heat dissipation structure design can effectively extend the service life of the downlight and enhance the reliability thereof.

Furthermore, according to one embodiment of the present invention, the ultra-thin structural design of the downlight significantly reduces the thickness thereof, so it is convenient to install the downlight. Thus, the user can more easily install the downlight on various types of ceilings or walls, suitable for various buildings. At the same time, this structural design provides more possibilities for interior design to optimize the overall lighting effect. Therefore, the practicality of the downlight can be greatly enhanced. As set forth above, the downlight with screw-free fixation structure according to the embodiments can definitely achieve great technical effects.

Please refer to FIG. 7, which is a schematic view of installing the downlight with screw-free fixation structure in accordance with another embodiment of the present invention. Please also refer to FIG. 1, FIG. 2, FIG. 3 and FIG. 4. As shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4, the downlight 1 includes a lamp body 11, a light source board 12, a light cover 13, a control box 14, a switch module 15, two spring latches 16, and a power cable 17.

The lamp body 11 has a central hole 111, an inner ring body 112, four protrusions 113, and two holders 114.

The inner ring body 112 is disposed on the inner edge of the lamp body 11 and partially covers the central hole 111. One side of the inner ring body 112 has a plurality of locking points LP.

One end of the power cable 17 is connected to the control box 14, and the other end of the power cable 17 is connected to an external power source (such as mains electricity, generator, etc.).

The two holders 114 are disposed on one side of the lamp body 11, and two spring buckles 16 are respectively fixed on the two holders 114.

Similarly, as described above, the downlight 1 has a screw-free fixation structural design, so the light source board 12 can be fixed by a screw-free fixing mechanism, which can reduce the time and manpower costs in the production process and reduce the risk of human error. Furthermore, the screw-free fixation structural design does not require additional fixing components, thereby reducing material costs. Therefore, the production cost of the downlight 1 can be greatly reduced, and the production efficiency can be effectively improved.

Besides, via the above structure design, the control box 14 does not face the light-emitting surface of the light source board 12. Therefore, the control box 14 and the switch module 15 do not affect the light-emitting effect of the light source board 12, and the user can conveniently operate the switch module 15 to turn the downlight 1 on or off, or adjust the brightness or color temperature of the downlight 1. Therefore, the light-emitting effect of the downlight 1 can be effectively improved, so the downlight 1 can be more convenient in use in order to provide the user with a great user experience.

As shown in FIG. 5, the inner ring body 112 has two plate bodies PB, and the two locking points LP are respectively disposed on the two plate bodies PB.

As shown in FIG. 6, the user can align the four straight sides 121 of the light source board 12 with the four protrusions 113 on the inner edge of the lamp body 11 and place the light source board 12 on the inner ring body 112. Then, the user can apply pressure towards the inner ring body 112 to press the light source board 12 to make the light source board 12 press the two locking points LP on the two plate bodies PB of the inner ring body 112. At this point, the two plate bodies PB pressed by the light source board 12 can provide resilience, causing the two locking points LP to be in an interference fit with the light source board 12. Subsequently, the user can rotate the light source board 12 to make the four slots GV of the lamp body 11 be engaged with the light source board 12. Finally, the user can stop rotating the light source board 12 when the two locking points LP are respectively inserted into the two fixing holes 112 of the light source board 12, and the structural strength of the plate bodies PB prevents the two locking points LP from disengaging from the two fixing holes 112 of the light source board 12.

Consequently, the light source board 12 is engaged with the four slots GV of the lamp body 11, and the two locking points LP are respectively inserted into the two fixing holes 112 of the light source board 12.

As shown in FIG. 7, when the downlight 1 is installed on the ceiling CE, the two spring buckles 16 can secure the downlight 1 to the ceiling CE.

Additionally, the distance Sd between the control box 14 and the central axis Mx of the central hole 111 of the lamp body 11 is greater than half the radius Rd of the central hole 111 of the lamp body 11. The side-mounted control box design creates a vacant space on one side of the control box 14. Consequently, when the downlight 1 is installed on the ceiling CE, the vacant space can be used to accommodate the beam BH or similar items, thereby avoiding the influence of the building structure on the installation of the downlight 1. Therefore, the downlight 1 can be applied to various buildings, making its application more extensive and flexible.

Similarly, with the aforementioned screw-free fixation structural design, the downlight 1 can secure the light source board 12 through a screw-free fixation mechanism, reducing time and manpower costs during production, and minimizing the risk of human error. Moreover, the screw-free fixation structural design does not require additional fixing components, thereby reducing material costs. Consequently, the production cost of the downlight 1 can be significantly reduced, and production efficiency enhanced.

Furthermore, as mentioned earlier, the light source board 12 has the fixing holes 122, while one side, corresponding to the light source board 12, of the inner ring body 112 is provided with the locking points LP, with each locking point LP inserted into each fixing hole 122. Through the slots GV, fixing holes 122, and locking points LP, a multifunctional fixing effect can be achieved, not only achieving a snap-fit effect but also a press-fit effect. Therefore, the screw-free fixation structural design with multifunctional fixing effect can more stably secure the light source board 12, enhancing the overall structural stability of the downlight 1.

As mentioned previously, the downlight 1 also includes a switch module 15 and a control box 14, with the switch module 15 set inside the control box 14, and the control box 14 not facing the light-emitting surface of the light source board 12. Consequently, the control box 14 and the switch module 15 do not affect the light-emitting effect of the light source board 12, and users can conveniently operate the switch module 15 to turn the downlight 1 on or off, or adjust the brightness or color temperature thereof. Thus, the light-emitting effect of the downlight 1 can be effectively enhanced, and the downlight 1 can be more convenient in use with a view to providing the user with a great user experience.

Similarly, the light source board 12 is disposed on the inner ring body 112 and inside the central hole 111, with the inner ring body 112 partially covering the light source board 12. Consequently, one side of the light source board 12 can be partially exposed from the inner ring body 112, allowing the light source board 12 to dissipate heat through the structure mentioned above, preventing damage due to overheating. This special heat dissipation structural design can effectively extend the service life of the downlight 1 in order to improve the reliability of the downlight 1.

The present invention also provides downlight 1 with side-mounted control box, which includes a lamp body 11, a light source board 12, and a control box 14. The lamp body 11 has a central hole 111 and an inner ring body 112. The inner ring body 112 is disposed on the inner edge of the lamp body 11 and partially covers the central hole 111. The light source board 12 is disposed on the inner ring body 112 and inside the central hole 111. The light source board 12 is disc-shaped. The control box 14 is disposed on one side of the lamp body 11. The shortest distance from the control box 14 to the central axis Mx of the central hole 111 is greater than half the radius of the central hole 111.

In one embodiment, the downlight 1 further includes a power cable 17. The control box 14 is connected to an external power source via the power cable 17.

In one embodiment, the downlight 1 also includes a switch module 15. The switch module 15 is disposed inside the control box 14 and electrically connected to the light source board 12.

In one embodiment, the lamp body 11 also includes a plurality of protrusions 113. The protrusions 113 are distributed on the inner edge of the lamp body 11 and surround the central hole 111. The protrusions 113 and the inner ring body 112 form a plurality of slots GV, with the light source board 12 being engaged with the slots GV.

In one embodiment, the light source board 12 has a plurality of straight sides 121.

In one embodiment, the number of the straight sides 121 is greater than or equal to the number of the slots GV.

In one embodiment, the light source board 12 has a plurality of fixing holes 122. One side, corresponding to the light source board 12, of the inner ring body 112 is provided with a plurality of locking points LP. The locking points LP are inserted into the fixing holes 122 respectively.

In one embodiment, the number of the fixing holes 122 is greater than or equal to the number of the locking points LP.

In one embodiment, the inner ring body 112 partially covers the light source board 12, allowing one side of the light source board 12 to be partially exposed from the inner ring body 112.

In one embodiment, the downlight 1 further includes a light cover 13. The light cover 13 is disposed on the other side of the lamp body 11, covering the central hole 111 and the other side of the light source board 12.
