Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to fig. 3, the panel light in this embodiment includes a chassis 1 having a cavity with a downward opening, a light emitting module 2 and a light guiding module 3 disposed in the chassis 1, and a light-transmitting plate 4 covering the opening of the chassis 1. The light emitting component 2 is annular and is arranged on the periphery of the light guide component 3.

The chassis 1 can be formed by plastic injection molding or by direct integral stamping of metal parts. Be equipped with recess 11 along circumference on the medial surface of chassis 1, light-passing board 4 joint is in the recess 11, and then realize the installation of light-passing board 4 on chassis 1. In this way, the light guide assembly 3 is correspondingly arranged above the light-transmitting plate 4, and at the same time, forms a support for the light-emitting assembly 2. The groove 11 is formed in the edge of the bottom plate 1, so that the lower edge of the bottom plate 1 is not exposed below the light-transmitting plate 4 too much, and the structure is more attractive.

The cross-section of recess 11 is the arc in this embodiment, so is convenient for light-passing board 4 to install. During the installation, through light-passing board 4's small deformation, push light-passing board 4 into recess 11 in, the installation operation is very convenient.

Usually the thickness of cavity can be greater than leaded light subassembly 3 in the chassis 1, for better fixed leaded light subassembly 3, avoids leaded light subassembly 3 to take place to rock in chassis 1 and influence the light-emitting effect, in this embodiment, is equipped with annular support ring 5 along circumference between leaded light subassembly 3 and the light-passing board 4. The top wall of the chassis 1 is at least provided with a concave part 12 in the middle, and the light guide assembly 3 and the light transmission plate 4 are limited between the concave part 12 and the support ring 5. So through support ring 5 and lower recess 12 for the setting that leaded light subassembly 3 can be firm is in the cavity on chassis 1, avoids leaded light subassembly 3's stability, and the light guide effect can not be influenced correspondingly. The light emitting element 2 generates heat during operation, which is conducted to the light guiding element 3 in close proximity to the light emitting element 2, and the recess 12 is in contact with the light guiding element 3, thereby improving the heat dissipation of the light guiding element 3.

In order to realize the heat dissipation to light emitting component 2 as far as, light emitting component 2 includes annular flexible sheet and a plurality of LED lamps of setting on the flexible sheet inner peripheral surface, and the flexible sheet is fixed on chassis 1's inner peripheral surface, and the heat that light emitting component 2 during operation produced can be quick dispels the heat through chassis 1 for this panel light also can effectively realize the heat dissipation even do not additionally set up heat dissipation part, guarantees the normal work of panel light. In order to improve the radiating effect of flexible board, the flexible board in this embodiment adopts flexible aluminum material to make, and its heat dissipation is fast, does benefit to the life-span that improves the LED lamp, and the heat of conducting on the flexible board passes through the base and expands to the external environment again. The light emitted from the light emitting assembly 2 is printed on teeth based on the structure of the light emitting assembly, and this problem is solved by the structure of the support ring 5 described below in this embodiment.

The support ring 5 in this embodiment is inclined radially outward from top to bottom, the cross section of the support ring 5 is wedge-shaped, that is, the thickness of the upper part of the support ring 5 is greater than that of the lower part, the top surface of the support ring 5 is planar and is attached to the lower surface of the light guide assembly 3, and the lower edge of the support ring 5 extends to the connection between the inner side wall of the chassis 1 and the light-transmitting plate 4, that is, the lower edge of the support ring 5 extends to the position where the upper part of the groove 11 is connected with the light-transmitting plate 4. Through this support ring 5 for form the clearance space between light guide component 3 and the light-passing board 4, make on the one hand the light of 3 outputs of light guide component have longer propagation path before penetrating light-passing board 4, the light of each direction jets out again after fully mixing in this clearance space, makes the light of jetting out from light-passing board 4 more even, soft, and light is more comfortable, and the difficult light that appears the tooth seal form. On the other hand, the support ring 5 shields the light emitted from the light emitting component 2 directly or through a short light guide path at a position close to the light emitting component 2, so that the light at the position where the tooth-printed light is most concentrated can be shielded, the tooth-printed light is prevented from being emitted directly, and the uniformity of the emitted light is improved. In addition, the support ring 5 is inclined outwards from top to bottom along the radial direction, so that the area of the light emitting surface is not affected, and the area of the light emitting surface is maximized.

The light guide assembly 3 comprises a light guide plate 31 and reflective paper 32 arranged above the light guide plate 31, wherein the reflective paper 32 can be made of environment-friendly PET materials, and the reflective paper 32 can transmit and reflect light so as to reflect the light to the light guide plate 31 and reduce the loss in the light transmission process. The light guide plate 31 is made of a high-light-transmission PMMA material, the light guide plate 31 made of the material has high light transmittance, and the emitted light can achieve a soft and non-dazzling light emitting effect, so that the light emitting uniformity is improved. The light guide plate 31 is made of PMMA material, which is beneficial to the optical analysis and design of the light guide plate 31, and is convenient for the automatic production of the light guide plate 31.

The light-transmitting plate 4 can be an environment-friendly high-light-transmittance quality plastic flat plate, the thickness of the light-transmitting plate 4 is specifically selected according to needs, the light-transmitting plate 4 can prevent external sundries from entering the chassis 1, and meanwhile, the light-transmitting plate can also play a good role in light transmission, so that a good light-transmitting effect is achieved.

The edge of the chassis 1 is also provided with a flange 13 which is turned outwards horizontally, and the upper surface of the flange 13 is provided with a gasket 6. For the sake of aesthetic property, the outer periphery of the turned-over edge 13 is also bent and extended upwards, so that when the turned-over edge 13 is observed from bottom to top, the edge of the turned-over edge 13 is smoothly transited, and the appearance is more beautiful. The gasket 6 can fill the space between the chassis 1 and the panel lamp mounting surface, and the influence of the unevenness of the mounting surface on the mounting attractiveness is avoided.

When the panel lamp is assembled, the chassis 1 can be inverted, and then the light emitting component 2, the light guide component 3 and the light transmission plate 4 are sequentially installed. After the light transmission plate 4 is installed, the installation is completed. The utility model provides a panel light is realizing the installation of light-passing board 4 through recess 11 on chassis 1 to utilize the installation of light-passing board 4 on chassis 1 to realize the support to light-emitting component 2, leaded light subassembly 3, this structural part is few, during the assembly, need not extra mounting, can realize the installation of each part on chassis 1, the assembly operation is more convenient.
