Description

Technical Field

[0001] This application belongs to the technical field of the housing components of equipment, and particularly relates to a housing for an LED floodlight. Background Art

[0002] An LED floodlight is a lamp that makes the brightness on a specified illuminated surface higher than the surrounding environment, also known as a spotlight. It is mainly used in large-area working sites, mine fields, building outlines, stadiums, overpasses, monuments, parks, flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights.

[0003] Among them, in this field, ordinary technicians generally regard the side with the LED light source as the front and the front side of the entire floodlight, and the opposite side as the back and the rear side; and when installing, the surface on the side of the fixing frame is the lower side. In a high-voltage floodlight with the publication number CN215982174U, in its overall structure, the lamp cover and the lamp body are connected front and back, and components such as circuit boards are fixed to the back of the lamp body through bolt parts. In an LED floodlight with a protection structure with the publication number CN214249307U, its lamp holder and the lamp cover housing are also fixed front and back.

[0004] In this regard, the applicant believes that arranging the bolt fasteners on the back of the floodlight affects the overall aesthetics of the floodlight, and the front-and-back fastening method is not conducive to the waterproofing of the floodlight. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the existing problems, and provides a housing structure in which the lamp body is arranged inside the housing, and the openings for the lamp body to enter and exit the housing are opened on the lower side.

[0006] In order to achieve the above technical purpose, the following technical solution is now provided. A housing for an LED floodlight includes a housing base body. The housing base body has a first opening, and the first opening is the placement opening for the LED light-emitting lamp. The housing base body has a second opening, and the second opening is located on one of the adjacent sides of the first opening and serves as the inlet and outlet for the internal component group.

[0007] In this technical solution, the surface where the first opening is located is considered the front by those skilled in the art. The sides adjacent to this front are considered the left and right sides and the upper and lower sides by those skilled in the art. Among them, the second opening of this technical solution is located on the adjacent side of the first opening. In the view of those skilled in the art, its set position is on the upper side or the lower side, because brackets must be provided on the left and right sides, which can also be directly obtained from the comparative documents; and the purpose in this technical solution is for aesthetics and waterproofing, so this side is preferably the lower side. Only the lower side is the side that consumers do not pay attention to, and rainwater will not easily splash on and seep into the interior of the floodlight.

[0008] In an implementable manner, connection feet of a fixing bracket are arranged on a pair of side surfaces on both sides of the first opening, and the fixing bracket can pass through the front of the second opening when the connection feet are rotated to a proper angle. It is determined that the surface where the second opening is located is below the fixing bracket.

[0009] In an implementable manner, the second opening has fixing bases located inside the housing base at four vertices, and bolt holes are arranged inside the fixing bases.

[0010] In an implementable manner, two fixing bases at the first opening are first base blocks, and the remaining two fixing bases are base strips, and the base strips penetrate through the housing base.

[0011] In an implementable manner, the first opening has base blocks located inside the housing base at four vertices, where the ones adjacent to the second opening are first base blocks; the remaining two are second base blocks; limiting rods pointing to the first opening are arranged on the first base blocks and the second base blocks. The edge of the first opening is basically flush with the inner surface of the inner cavity of the housing, and only the first base blocks and the second base blocks are left for limiting, which ensures that the heat in the inner cavity of the housing can also be dissipated from the first opening.

[0012] In an implementable manner, an auxiliary part for limiting and protecting the LED light is arranged at the first opening. The auxiliary part includes a decorative plate arranged on the limiting rod and engaged with each LED light bead; it also includes a glass baffle glued to the inner side of the first opening; and the free end of the limiting rod abuts against the glass baffle.

[0013] In an implementable manner, a card slot for limiting a bottom plate on which a light is installed is arranged inside the housing base. The card slot is linear and points from the housing base to the second opening.

[0014] In an implementable manner, a dial for displaying the rotation angle is arranged on the connection foot. After the dial and the connection foot are matched, they are fixed to the housing base by countersunk head rivets.

[0015] In an implementable manner, a light-shielding cover sleeved outside the housing base is arranged between the housing base and the connection foot. The light-shielding cover has an extension at the first opening; when the light-shielding cover is installed or disassembled, it slides along the direction of the first opening.

[0016] The utility model has the following beneficial effects compared with the prior art:

[0017] The housing is integrally formed, and has a first opening for the LED to emit light in the front and a second opening on the side of the first opening as the inlet and outlet of the lamp body, realizing the full coverage of the housing for the lamp body. And the structure of the lamp cover enables the lamp body to only slide into the housing through the guide rail, saving the use of fixing parts, ensuring that the housing is a whole structure, and realizing the beauty and waterproofness of the outer shell.

[0018] The edge of the first opening fits against the inner surface of the housing base, that is, the area is the same as the cross-section of the housing base, and only the base block is left for fixing so that the first opening still has the function of heat dissipation. The setting of the internal card slots in the housing base enables clear division of each area inside the housing and effective fixation. Description of the Drawings
