[0020] Figure 1 is an exploded structural schematic diagram of the panel light according to the embodiment of the present utility model;

[0021] Figure 2 is a cross-sectional view of the panel light according to the embodiment of the present utility model. Detailed Embodiments

[0022] This embodiment provides a panel light conducive to heat dissipation, as Figure 1 and Figure 2 shown. It includes a heat dissipation housing 1, an EVA buffer cotton 2, a light guide plate 3, a diffusion plate 4, a heat dissipation ring 5, and a light source board 6. The heat dissipation housing 1 is made of aluminum alloy, and the heat dissipation ring 5 is a metal ring, specifically an aluminum ring.

[0023] The heat dissipation housing 1 is in a plate-like structure. The heat dissipation ring 5 is in a circular shape and is tightly sleeved on the edge of the heat dissipation housing 1, and the heat dissipation ring 5 is in surface contact with the heat dissipation housing 1. The light source board 6 is firmly attached to the inner wall of the heat dissipation ring 5. The EVA buffer cotton 2, the light guide plate 3 and the diffusion plate 4 are all circular and are arranged below the heat dissipation housing 1 and within the heat dissipation ring 5. Among them, the EVA buffer cotton 2 and the diffusion plate 4 are optional. In this way, the light source board 6 is located between the light guide plate 3 and the heat dissipation ring 5, so that the emitted light of the light source board 6 is directly opposite to the outer side wall of the light guide plate 3.

[0024] Specifically, the heat dissipation ring 5 is formed by enclosing an outer side plate 51, a top plate 52, an inner side plate 53 and a bottom plate 54. The top plate 52 and the inner side plate 51 are perpendicular to each other. The light source board 6 is attached to the outer wall of the inner side plate 51 facing the center of the light guide plate 3. The edge of the heat dissipation housing 1 is fixedly installed on the top plate 51 of the heat dissipation ring 5 by screws to ensure close surface contact between the two, which is beneficial to heat dissipation. The bottom plate 54 is provided with a heat dissipation arc surface 541. The arc surface design can increase the surface area of the heat dissipation ring 5 and further facilitate heat dissipation. Preferably, the heat dissipation arc surfaces 541 of the entire heat dissipation ring 5 are connected to form a spherical zone surface or a surface close to a spherical zone surface, and the center of the spherical zone surface is located below the light guide plate 3. In this way, while ensuring the heat dissipation effect, it is also beneficial to light emission. The outer side plate 51 covers or shields the edge of the heat dissipation housing 1.

[0025] The panel light further includes a mounting bracket 7. The upper part of the heat dissipation housing 1 is provided with a mounting part 11. The mounting bracket 7 is fixedly installed with the heat dissipation housing 1 through the mounting part 11, so as to realize the fixation of the mounting bracket 7 and the panel light, and then the panel light is installed on the required panel through the mounting bracket 7.

[0026] More specifically, the mounting bracket 7 is a cross bracket. The mounting part 11 protrudes upward. The four ends of the cross bracket are all bent downward and buckled on the mounting part 11. Four L-shaped grooves 12 are provided at the edge of the mounting part. The four ends of the mounting bracket 7 are fixedly corresponded to the four L-shaped grooves 12 through bolts, and the bolts 8 pass through the innermost ends of the L-shaped grooves 12.

[0027] Alternatively, each of the four ends of the cross bracket is provided with a mounting bolt. The mounting bolt enters from the opening of the L-shaped groove 12, and by rotating the mounting bracket 7, the mounting bolt is moved into the innermost end of the L-shaped groove 12 to realize the snap fixation of the mounting bracket 7 and the heat dissipation housing 1.

[0028] In fact, the connection relationship between the heat dissipation housing and the heat dissipation ring can be various. For example, the edge of the heat dissipation housing can also cover the heat dissipation ring, as long as the heat dissipation ring and the heat dissipation housing can be closely attached to achieve heat conduction and at the same time ensure the mechanical seal of the two.

[0029] The above embodiments are only the preferred embodiments of the present utility model, and cannot be used to limit the scope of protection of the present utility model. Any non-substantive changes and substitutions made by those skilled in the art based on the present utility model shall fall within the scope of protection required by the present utility model.
