The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, a driving pre-installed backlight structure 10 of an embodiment includes a pre-installed base 100 and a mounting component 200. The mounting component 200 is used to be set on a light source lamp panel 21, and locks the light source lamp panel 21 on the pre-installed base 100. Specifically, the locking is a rotation locking or a snap-on locking. In this embodiment, the locking is a rotation locking.

[0037] The driving pre-installed backlight structure 10 also includes a hollow sheet frame 300, a driving module 400 and a backlight assembly 500. A hollow area is opened in the pre-installed base 100, the hollow sheet frame 300 is arranged in the hollow area, the driving module 400 is arranged on the hollow sheet frame 300 and accommodated in the hollow area, and a wiring terminal 401 is arranged on the driving module 400. The wiring terminal 401 is used to connect the wires of the building body, so that the wires pass through the hollow area and are connected to the wiring terminal 401, thereby energizing the driving module 400.

[0038] In this embodiment, a plurality of hollow openings 110 are provided on the pre-installed base 100, and the hollow openings 110 and the hollow sheet frame 300 are avoided. Furthermore, the hollow openings 110 and the hollow sheet frame 300 are combined into a hollow area. When the driving module 400 is working, the heat generated by the work is dissipated from the pre-installed base 100 through the hollow openings 110 to achieve a better heat dissipation effect and ensure the normal operation of the lamp.

[0039] like Figure 1 and Figure 4 As shown, in one embodiment, the backlight assembly 500 includes a light source 510 and a dimming element 520. The light source 510 is disposed around the side of the pre-installed base 100. The light source 510 is also electrically connected to the power terminal of the driving module 400. The dimming element 520 is disposed around the light-emitting surface of the light source 510, and the dimming element 520 and the light source 510 are disposed concentrically. Further, the dimming element 520 is a silicone lens, which is used to reduce the glare value of the light irradiated by the light source 510, thereby making the light softer.

[0040] In this embodiment, if Figure 2 As shown, the light source component 510 is completely arranged around the side of the pre-installed base 100. Furthermore, when the light source component 510 is powered on, the light generated by the light source component 510 will be transmitted through the dimming component 520 to irradiate the periphery of the pre-installed base 100 to achieve the effect of supplementary backlighting. Such a structure and the position of the light source component 510 do not affect the overall structure of the pre-installed base 100, and thus the flatness of the pre-installed base 100 is better.

[0041] Of course, the light source 510 is not limited to being completely arranged around the side of the pre-installed base 100. In another embodiment, the light source 510 is partially arranged around the side of the pre-installed base 100 to achieve the effect of supplementary backlighting. The effect diagram is shown in FIG. Figure 3 shown.

[0042] In one embodiment, the pre-installed base 100 is an annular base. It is understood that when the pre-installed base 100 is an annular base, the light source 510 is disposed around the side of the pre-installed base 100, so that when the light source 510 is powered on and irradiates light, the periphery of the pre-installed base 100 can be illuminated to achieve the effect of supplementary backlighting. Of course, the pre-installed base 100 is not limited to an annular base. In other embodiments, the pre-installed base 100 can also be a square base, a pentagonal base, a hexagonal base, etc.

[0043] like Figure 5 As shown, in one embodiment, the pre-installed base 100 is provided with a limiting groove 120, the limiting groove 120 is arranged toward the hollow sheet frame 300, and a part of the structure of the driving module 400 abuts against the inner wall of the limiting groove 120. It can be understood that the driving module 400 is detachably mounted on the hollow sheet frame 300, and when the driving module 400 is installed, the driving module 400 is installed on the hollow sheet frame 300, wherein a part of the structure of the driving module 400 abuts against the limiting groove 120, so that the driving module 400 is stably installed without deviation, and ensures that the power terminal of the driving module 400 is electrically connected to the light source component 510.

[0044] like Figure 5 and Figure 6 As shown, in one embodiment, a clamping protrusion 410 is convexly provided on one side of the driving module 400, and a connecting port 121 is provided on the inner wall of the limiting groove 120, and the clamping protrusion 410 is clamped in the connecting port 121. It can be understood that when the driving module 400 is installed so that a part of the structure of the driving module 400 abuts against the inner wall of the limiting groove 120, the clamping protrusion 410 is clamped in the connecting port 121, so that the driving module 400 is preliminarily connected to the pre-installed base 100.

[0045] In one embodiment, there are multiple locking protrusions 410 .

[0046] In one embodiment, there are multiple connection ports 121 .

[0047] Furthermore, when the number of the snap-fitting bosses 410 and the connection ports 121 is multiple and equal, each snap-fitting boss 410 is snap-fitted to the corresponding connection port 121, so that the driving module 400 is initially connected to the pre-installed base 100, and the driving module 400 is not prone to positional displacement.

[0048] like Figure 5 and Figure 6As shown, in one embodiment, the driving module 400 is provided with a power connection part 420, and the inner wall of the limiting groove 120 is provided with a power terminal 122, the power connection part 420 is electrically connected to the power terminal 122, and the light source part 510 is electrically connected to the power terminal 122. It can be understood that when the driving module 400 is initially connected to the pre-installed base 100, the power connection part 420 is in contact with the power terminal 122. When the driving module 400 is powered on, the power connection part 420 is powered on and connected to the power terminal 122. Since the power terminal 122 is electrically connected to the light source part 510, the light source part 510 is powered on to illuminate the periphery of the pre-installed base 100.

[0049] like Figure 4 As shown, in one embodiment, the pre-installed base 100 includes an annular upper cover 101, an annular lower cover 102 and a mounting plate 103 connected in sequence, the power terminal 122 is arranged on the annular upper cover 101, the backlight assembly 500 is arranged on the outer peripheral side of the annular lower cover 102, and the hollow sheet frame 300 is arranged on the mounting plate 103. In this embodiment, the annular upper cover 101 and the annular lower cover 102, and the annular lower cover 102 and the mounting plate 103 are all connected by screws. When the annular upper cover 101, the annular lower cover 102 and the mounting plate 103 are combined into the pre-installed base 100, since the backlight assembly 500 is arranged on the outer peripheral side of the annular lower cover 102, and the driving module 400 is installed in the pre-installed base 100, its power connection part 420 contacts the power terminal 122, so as not to affect the overall structure of the pre-installed base 100, that is, the flatness of the pre-installed base 100 is better.

[0050] like Figure 1 and Figure 2 As shown, in one embodiment, the driving pre-installed backlight structure 10 further includes a locking member 600, the driving module 400 is provided with a through hole, the hollow sheet frame 300 is provided with a screw hole 301, the threaded portion of the locking member 600 passes through the through hole and is located in the screw hole 301, and the top of the locking member 600 abuts against the driving module 400. It can be understood that after the driving module 400 is initially connected to the pre-installed base 100, the driving module 400 and the hollow sheet frame 300 are fixed by the locking member 600, that is, the driving module 400 and the hollow sheet frame 300 are connected by screwing, so that the driving module 400 is further fixed in the pre-installed base 100.

[0051] like Figure 7 As shown, the present disclosure also provides a quick-connect ceiling lamp 20, including a light source lamp panel 21 and a driving pre-installed backlight structure 10 of any of the above embodiments, wherein the light source lamp panel 21 is connected to the pre-installed base 100 via a mounting member 200. Further, the light source lamp panel 21 can be screwed or snapped onto the pre-installed base 100 via the mounting member 200.

[0052] like Figure 6 and Figure 7As shown, in one embodiment, the light source lamp panel 21 is provided with a power supply seat 21a, and the driving module 400 is provided with a power supply ring 430, and the power supply ring 430 is electrically connected to the power supply seat 21a. It can be understood that after the light source lamp panel 21 is connected to the pre-installed base 100, the power supply ring 430 contacts the power supply seat 21a, and when the driving module 400 is powered on, power can be connected between the power supply ring 430 and the power supply seat 21a, so that the light source lamp panel 21 is powered on and performs lighting work.

[0053] Compared with the prior art, the present invention has at least the following advantages:

[0054] 1. The above-mentioned driving pre-installed backlight structure 10 includes a hollow sheet frame 300, and the driving module 400 is arranged on the hollow sheet frame 300 and located in the hollow area. When the driving module 400 is powered on, the heat generated by the work is dissipated through the hollow area, so that the heat dissipation effect of the driving module 400 is better.

[0055] 2. The above-mentioned driving pre-installed backlight structure 10 also includes a backlight component 500, and the backlight component 500 is arranged in the pre-installed base 100, wherein the light source component 510 surrounds the side of the pre-installed base 100, so that when the driving module 400 is powered on, the light source component 510 is energized, and the light source component 510 illuminates the periphery of the pre-installed base 100 through the dimming component 520 to achieve the effect of supplementing the backlight, and does not affect the overall structure of the pre-installed base 100, so that the flatness of the pre-installed base 100 is better.

[0056] The above embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
