Description

Technical Field

[0001] The utility model relates to the technical field of LED floodlights, in particular to a housing of an LED floodlight with high heat dissipation efficiency. Background Art

[0002] A floodlight is a lamp with a higher illuminance on the designated illuminated surface than the surrounding environment. It is also called a spotlight. Usually, it can be aimed in any direction and has a structure that is not affected by climatic conditions. It is mainly used in large-scale mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc.

[0003] At present, the installation of floodlights needs to be adjusted according to the actual application situation, so the bases of existing floodlights are mostly U-shaped, in order to facilitate installation and be able to perform pitch adjustment within a certain range. However, in the prior art, the overall adjustment range is small, and after installation, it can only be adjusted around the connection between the U-shaped bracket and the floodlight. Once the installation is completed, it cannot be adjusted horizontally, which increases the difficulty of installation and requires repeated measurements before fixing. In addition, the lighting angle adjustment is also limited to a certain range. In view of this, we propose an LED floodlight housing with high heat dissipation efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide an LED floodlight housing with high heat dissipation efficiency, which can solve the problem that it is difficult to adjust the lateral angle due to the inability to rotate and adjust.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a housing of an LED floodlight with high heat dissipation efficiency comprises a mounting chassis, the upper surface of the mounting chassis is fixedly connected with a threaded sleeve, the upper surface of the mounting chassis is provided with a rotating disk, the upper surface of the rotating disk is fixedly connected with a limiting ring, the outer surface of the threaded sleeve is sleeved with a second limiting ring, the inner wall of the limiting ring is provided with a rotating groove matched with the second limiting ring, the limiting ring is rotatably sleeved on the outer surface of the threaded sleeve, the upper end of the threaded sleeve extends out of the upper surface of the limiting ring, the internal thread sleeve of the threaded sleeve is sleeved with a locking bolt, the upper surface of the rotating disk is fixedly connected with two brackets, a floodlight is rotatably connected between the two brackets, the outer surface of the mounting chassis is fixedly connected with two mounting ears, the upper surfaces of the two mounting ears are provided with second bolts, and the lower ends of the two second bolts are respectively threaded through the lower surfaces of the two mounting ears.

[0006] Preferably, the outer surface of the mounting chassis is provided with a scale groove, and the outer surface of the rotating disk is provided with an indication groove.

[0007] Preferably, a mounting compartment is provided inside the floodlight, an air inlet is provided on the front surface of the floodlight, and a filter is fixedly connected to the inner wall of the air inlet.

[0008] Preferably, the other side of the air inlet extends into the interior of the installation compartment, and an air outlet is provided on the rear surface of the floodlight.

[0009] Preferably, a second filter is fixedly connected to the inner wall of the air outlet, and a cooling fan is provided on the inner wall of the air outlet.

[0010] Preferably, heat dissipation plates are provided on four side surfaces of the floodlight.

[0011] Preferably, one side surface of the four heat dissipation plates close to the floodlight is fixedly connected to a heat conducting plate, and the other side surface of the heat conducting plate extends into the interior of the air inlet.

[0012] Preferably, a third bolt for installation is provided on a surface of the heat dissipation plate on one side away from the floodlight.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The housing of the LED floodlight with high heat dissipation efficiency will gradually move downward when the locking bolt is rotated by tightening the locking bolt again. After the locking bolt is lowered, the nut at its upper end contacts the upper surface of the limit ring to complete the locking. Through the above structure, when the lateral angle of the floodlight needs to be adjusted, it only needs to be disassembled and reinstalled. It can be rotated and adjusted by loosening the locking bolt, which improves its adjustment speed and increases its practicality.

[0015] 2. The housing of the LED floodlight with high heat dissipation efficiency allows cold air to cool the components in the installation compartment and then be discharged through the exhaust port. The second filter can prevent the cooling fan from being exposed and prevent debris from entering it. Through the above structure, not only can the adjustment accuracy be improved through the cooperation of the scale groove and the indicator groove, but the subsequent heat dissipation structure can also be used to ensure that the floodlight will not malfunction due to heat accumulation caused by long-term internal operation during use, thereby increasing the service life of the floodlight.
