Description

Technical Field

[0001] The utility model relates to the field of lighting, in particular to the technical field of LED ceiling lamps. Background Art

[0002] In traditional ceiling lamps, the lamp beads are concentrated in the middle, and the heat generated by such concentration of lamp beads is also concentrated. If the heat dissipation design of the lamp is not good enough, the temperature in the middle may be too high. The concentrated lamp beads may accelerate the light decay under long-term high temperature operation, reducing the effective service life of the lamp.

[0003] At the same time, the concentration of lamp beads will produce a strong light spot, resulting in uneven light in the lighting area, affecting the comfort and practicality of the lighting.

[0004] However, the conventional design of dispersed lamp beads also has problems. The first is the increase in cost and maintenance difficulty. The second is the difficulty in performance. When the lamp beads are dispersed and the brightness is high, the brightness of the lamp beads in the concentrated part will be high, causing certain visual interference to the human eye.

[0005] Therefore, how to improve heat dissipation performance while solving the problem of uneven light has become a topic that needs to be improved in the lighting industry. Utility Model Content

[0006] In view of the above technical limitations, the utility model aims to design an LED ceiling lamp to solve the problems of heat dissipation and lighting uniformity.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An LED ceiling lamp comprises a chassis and a mounting bracket arranged on the upper part of the chassis, wherein the chassis comprises an outer ring wall arranged on the outer periphery and a positioning ring wall arranged on the inner periphery of the outer ring wall;

[0009] It also includes a first LED light strip, a light panel, and a light housing which are sequentially arranged at the lower part of the chassis;

[0010] The first LED light strip is arranged on the inner side of the outer ring wall, the light board is in contact with the positioning ring wall, and the light housing supports the first LED light strip and the light board.

[0011] Compared with the prior art, this case utilizes the outer ring wall on the outer periphery of the chassis and the positioning ring wall on its inner periphery to form an annular space, and arranges a first LED light strip on the inner periphery of the outer ring wall to disperse the light points, thereby improving the heat dissipation problem and uneven light caused by the concentration of light points.

[0012] In some embodiments, a second LED light strip is provided on the periphery of the positioning ring wall to supplement the light source.

[0013] In some embodiments, the positioning ring wall is provided with a positioning opening, and the inner periphery of the positioning ring wall corresponding to the positioning opening is provided with a positioning column for fixing the second LED light strip. The positioning opening facilitates fixing the second LED light strip while taking into account heat dissipation and light transmission.

[0014] In some embodiments, the positioning ring wall is provided with at least one light-transmitting opening to supplement the heat dissipation and light-transmitting effects.

[0015] Preferably, an arc-shaped ring inclined downward toward the outer ring wall is provided between the positioning ring wall and the outer ring wall of the chassis, so that an optical angle is formed between the positioning ring wall and the outer ring wall, and the light output is more uniform.

[0016] In some embodiments, a light-transmitting lamp holder is further included and is disposed between the first LED light strip and the positioning ring wall. The lamp holder is located on the upper portion of the second LED light strip and serves to provide a uniform light effect for the light of the second LED light strip.

[0017] In some embodiments, the positioning ring wall is provided with at least one wire opening to facilitate the connection between the LED light strip and the circuit board.

[0018] Preferably, the light board includes a first light board and a second light board which are sequentially arranged at the lower part of the chassis.

[0019] Preferably, the thickness of the first lamp board is smaller than that of the second lamp board, so that sufficient light can be irradiated through the thin first lamp board, and then the light can be distributed more evenly through the thicker second lamp board.

[0020] In some embodiments, a support ring capable of supporting a light board is provided in the middle of the chassis, so as to support the installation of the light board and avoid excessive light being concentrated in the middle. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0030] Please refer to the installation and structure of the LED ceiling lamp of this utility model Figures 1 to 3 The LED ceiling lamp of this case includes a chassis 100 and a mounting bracket 200 mounted on the upper part of the chassis. The upper and lower positions are shown in the figure for the convenience of explanation, based on the corresponding directions when the LED ceiling lamp of this case is installed and used. The mounting bracket 200 is a component for mounting the LED ceiling lamp.

[0031] Embodiment 1.

[0032] The chassis 100 includes an outer ring wall 110 disposed on the outer periphery of the chassis 100. Specifically, a step 101 is formed between the outer ring wall 110 and the outermost side of the chassis 100. The outer periphery in the above description is close to the outer periphery based on the overall chassis 100. The outer periphery of the outer ring wall 110 includes at least one buckle 111, and the inner periphery includes at least one positioning groove 112. The positioning groove 112 can be formed by an L-shaped rib disposed on the inner side of the outer ring wall 110. At the same time, the chassis 100 also includes a positioning ring wall 120 on the inner periphery of the outer ring wall 110.

[0033] The circuit board 300, the first LED light strip 400, the light board 500, and the light housing 600 are arranged in sequence at the lower part of the chassis 100 of the LED ceiling lamp in this case. Specifically, the circuit board 300 is a device for controlling the light, which will not be described in detail here. The first LED light strip 400 is a light source rolled into a ring shape, which is inserted into the positioning groove 112 as described above, and then the light board 500 is installed, and the light board 500 conflicts with the positioning ring wall 120. Then the lamp housing 600 is inserted into the buckle 111 provided on the outer ring wall 110 of the chassis 100, and the outer wall of the lamp housing 600 can dock with the step 101. At this time, the lamp housing 600 can just support the first LED light strip 400 and the light board 500. That is, the first LED light strip 400 can be positioned by the upper and lower support of the positioning groove 112 and the lamp housing 600. And the light board 500 can be positioned by the support of the positioning ring wall 120 and the lamp housing 600.

[0034] In some preferred embodiments, the light board 500 may be configured as a first light board 510 and a second light board 520 sequentially arranged at the lower part of the chassis 100, and the thickness of the first light board 510 is less than the thickness of the second light board 520. Sufficient light can be irradiated through the thin first light board 510, and then the thicker second light board 520 can be used to make the light distribution more uniform.

[0035] In this way, the dispersed installation of the light source can be realized through a simple structure. And by utilizing the annular space formed between the outer ring wall 110 and the positioning wall ring 120, the first LED light strip 400 is arranged on the outer ring wall 110 to disperse the installation of the light source and disperse the light-emitting points, thereby improving the heat dissipation problem and uneven light caused by the concentrated light source.

[0036] Embodiment 2.

[0037] As for the light source, other light sources can be added to the annular space formed between the outer ring wall 110 and the positioning wall ring 120. Figures 3 to 5 On the basis of setting the light source on the outer ring wall 110, a second LED light strip 700 can be set on the periphery of the positioning ring wall 120. For specific installation methods, please refer to Figure 7 and Figure 8 . A positioning opening 121 is provided in the positioning ring wall 120, and the positioning opening 121 is provided in the lower part of the positioning ring wall 120, that is, the position facing the light board 500. A positioning column 122 for fixing the second LED light strip 700 is provided on the inner periphery of the positioning opening 121 of the positioning ring wall 120 corresponding to the positioning opening. Because the second LED light strip 700 has no support, it needs to be positioned from the positioning column 122 through the positioning opening 121. Here, it can be positioned by means of screws or gaskets, etc., and no specific limitation is made. Moreover, the positioning opening 121 can also play a role in heat dissipation and light transmission. Regarding the positioning of the second LED light strip 700, a plurality of positioning plates 123 can be provided on the outside of the positioning ring wall 120 to clamp the second LED light strip 700, which will not be repeated here.

[0038] Please refer to Figure 6 In some embodiments, in addition to the positioning opening 121, the positioning ring wall 120 may also be provided with at least one light-transmitting opening 124 to supplement the heat dissipation and light-transmitting effects. The number and position of the openings 124 may be adjusted as required.

[0039] In some embodiments, the positioning ring wall 120 may be provided with at least one wire opening 125 to facilitate the connection of the LED light strip and the circuit board 300. The LED light strip here refers to the first LED light strip 400 and the second LED light strip 700.

[0040] At this time, the second LED light strip 700 is located near the upper part of the chassis 100. Preferably, an arc ring 130 is arranged between the positioning ring wall 120 and the outer ring wall 110, which is inclined downward toward the outer ring wall 110. Compared with the flat plate form, the arc ring 130 forms an optical angle for the light source, and the light output is more uniform.

[0041] Furthermore, a light-transmissive lamp holder 800 is provided between the first LED light strip 400 and the positioning ring 120. The lamp holder 800 is located on the upper part of the second LED light strip 700, and plays a role in uniform light effect of the light of the second LED light strip.

[0042] Embodiment three.

[0043] In some embodiments, a support ring 140 is provided in the middle of the chassis 100 to support the light board 500, and is used to support the installation of the light board 500 and avoid too much light being concentrated in the middle. In particular, when multiple light sources are used, the problem of light being concentrated in the center will occur due to the ring-shaped light source design. The design of the support ring 140 can avoid the problem of light being concentrated in the center. At the same time, the mounting bracket 200 can be installed at the support ring 140.

[0044] As mentioned above, this case protects an LED ceiling lamp, and all technical solutions that are the same or similar to this case should be deemed to fall within the protection scope of this case.
