DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-3The utility model provides a technical solution for a hollow high-protection downlight: a hollow high-protection downlight, comprising a lamp body 1, wherein the lamp body 1 is divided into a power cavity 16 and a light source cavity 17, wherein the light source cavity 17 comprises a lens 4 at the outermost side of the lamp body 1, wherein a sealing groove is arranged in the lens 4, wherein a sealing ring 3 is arranged in the sealing groove, and a light source board 2 is arranged on the side of the sealing ring 3, wherein the power cavity 16 comprises a mounting bracket 13 in the lamp body 1, wherein a power box 11 is arranged in the mounting bracket 13, wherein a main board 10 is arranged in the power box 11, wherein a cable line 1 6 and two cable lines 2 15 are respectively arranged on the main board 10, wherein a power cover 9 is arranged on one side of the power box 11, wherein a protective coil 1 8 is arranged on the cable line 1 6, and protective coils 2 12 are arranged on the two cable lines 2 15, wherein the product is designed with a hollow separation structure, which not only forms an upward and downward air convection, realizes that a small size can achieve high power, but also realizes a high protection level of the product through chamber-type waterproofing, and at the same time, the product has a simple structure, fast assembly, and low labor cost.

[0020] See also Figure 1-3 A wire pressing piece 7 is provided on one side of the light source board 2, a sealing gasket 5 is provided between the light source board 2 and the wire pressing piece 7, a protective coil 3 14 is provided on the two cables 15, a hollow hole 1 is provided on the front of the lamp body 1, and a hollow hole 2 of the mounting bracket 13 is provided.

[0021] When in use, air enters the interior of the lamp body 1 through the hollow hole 1 on the front side of the lamp body 1. Since the power cavity 16 and the light source cavity 17 generate heat when the lamp is in use, the air entering the interior of the lamp body 1 through the hollow hole 1 will be heated. Then, by using the principle of thermal expansion and contraction of air, the density of the air will decrease after being heated and the volume will increase, thereby rising. After the hot air rises to the mounting bracket 13, it will be discharged from the hollow hole 2 of the mounting bracket 13 to the outside of the lamp body 1, thus forming a cycle of internal and external air convection, effectively taking away the heat inside the lamp body 1 and reducing the temperature of the lamp surface.

[0022] At the same time, the power cavity 16 and the light source cavity 17 inside the lamp are separated, and the space between them will also generate air flow, so that the power cavity 16 and the light source cavity 17 can be in full contact with the air, which can maximize the removal of heat generated when the lamp is in use, thereby reducing the temperature difference between the inner and outer surface temperatures of the lamp, effectively ensuring the service life of the product, and allowing the design of higher-power lamps in limited space.

[0023] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
