Description

Technical Field

[0001] The utility model belongs to the technical field of lighting equipment, and particularly relates to a floodlight with a U-shaped mounting bracket. Background Technique

[0002] The phenomenon of uneven light spot refers to the large difference in light intensity at different positions within the illumination area of the floodlight. In the design of the lamp, the light-emitting body, the light-emitting angle, and the layout of the reflector of the lamp will all affect the distribution of light. When these elements cannot be effectively coordinated, it will cause uneven light spots. In addition, uneven brightness distribution is also a common problem, especially in large-area lighting places, such as sports fields or squares. When the number of floodlights is insufficient or the installation height is unreasonable, it is easy to form bright areas and dark areas in certain areas, affecting the overall lighting effect.

[0003] In response to these problems, conventional countermeasures include using efficient optical designs, adding more floodlights to increase the overall lighting density, and using dimming technologies to improve the brightness distribution. Although these methods can improve the floodlight uniformity to a certain extent, there are also some drawbacks. Adding floodlights can effectively fill the shadow areas, but this will also lead to an increase in energy consumption and a heavier burden on equipment maintenance. Especially in large venues, the initial installation cost and the later operation cost may both increase significantly. Therefore, we hope to design a floodlight with a new structure to solve this problem. Content of the Utility Model

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a floodlight with a U-shaped mounting bracket, including: a floodlight body 100 and a heat dissipation component 200. A heat dissipation component 200 for rapid heat dissipation is fixed at the rear end of the floodlight body 100. The floodlight body 100 includes a lamp cover 110, a lamp housing 120, a fixing frame 130, and a dimming component 150;

[0027] The lamp cover 110 is installed on the upper side of the lamp housing 120 by screws. The fixing frame 130 is dampingly hinged to the rear end of the lamp housing 120. A dimming component 150 is installed inside the lamp housing 120, and a lamp board 160 is installed at the bottom of the lamp housing 120;

[0028] The heat dissipation component 200 includes a mounting plate 210, a protective net 230, an axial flow fan 240, and a mounting cylinder 250. A mounting cylinder 250 is integrally formed and stretched downward in the middle of the mounting plate 210. A protective net 230 is installed at the lower end of the mounting cylinder 250, and an axial flow fan 240 is installed inside the mounting cylinder 250 through the protective net 230.

[0029] Please refer to Figures 1 to 4 , a plurality of fins 121 are arranged at equal intervals on the rear surface of the lamp housing 120. Four reinforcing columns 122 with threaded holes 123 are arranged on the rear surface of the lamp housing 120, and the four reinforcing columns 122 are distributed in a rectangular structure.

[0030] The dimming component 150 includes a frosted reflector 151, a hammered reflector 152, and a mirror reflector 153. The mirror reflector 153 is placed at the bottom of the lamp housing 120, and the bottom of the mirror reflector 153 is sleeved on the upper edge of the lamp board 160.

[0031] The sectional length of the mirror reflector 153 gradually decreases from top to bottom. The upper end of the mirror reflector 153 abuts against the bottom of the hammered reflector 152;

[0032] The size and structure of the lower end of the hammered reflector 152 are both matched with the size and structure of the upper end of the mirror reflector 153. The sectional length of the hammered reflector 152 gradually decreases from top to bottom. The entire dimming component 150 forms a trapezoidal structure, which can make the projected light more uniform.

[0033] The lower end of the frosted reflector 151 abuts against the upper end of the hammered reflector 152. The size and structure of the lower end of the frosted reflector 151 are both matched with the size and structure of the upper end of the hammered reflector 152. The sectional length of the frosted reflector 151 gradually decreases from top to bottom.

[0034] As the first embodiment of the present utility model, in actual use, the light emitted by the LED lamp beads on the lamp board 160 diverges in all directions. The light projected onto the inner wall of the mirror reflector 153 is concentrated towards the middle part at the upper end of the dimming component 150 under the action of specular reflection. The concentrated light is projected through the hammer surface reflector 152. Part of the light is projected onto the inner wall of the hammer surface reflector 152. After the diffuse reflection on the inner wall of the hammer surface reflector 152, the light is concentrated again and becomes more uniform. When the light is about to be projected out of the lamp housing 120, it will pass through the frosted reflector 151. The light projected onto it undergoes diffuse reflection again. The frosted reflector 151, the hammer surface reflector 152, and the mirror reflector 153 cooperate together to not only ensure the irradiation intensity of the projected light, but also make the light distribution more uniform. Moreover, the two diffuse reflections can greatly reduce the dazzling effect of the light.

[0035] Please refer to Figures 1 to 5 , four corners of the upper surface of the mounting plate 210 are respectively penetrated downward to form a fixing hole 220. The number and distribution positions of the fixing holes 220 are matched with the number and distribution positions of the threaded holes 123;

[0036] The mounting plate 210 is fixed to the rear surface of the lamp housing 120 through the fixing holes 220, threaded holes 123, nuts, and bolts, and the mounting plate 210 does not directly contact the multiple fins 121.

[0037] As the second embodiment of the present utility model, in actual use, the mounting plate 210 does not directly contact the multiple fins 121 (nuts are installed between the mounting plate 210 and the strengthening columns 122 to lift the mounting plate 210). This means that the mounting plate 210 will not hinder the ventilation effect of the multiple fins 121. In a place with a relatively high temperature during use, when the floodlight body 100 is turned on, the axial flow fan 240 installed inside the mounting cylinder 250 is synchronously started. The axial flow fan 240 quickly pumps the outside air and blows it towards the lamp housing 120. This greatly increases the air flow rate between the multiple fins 121. After the heat generated by the lamp board 160 is transferred to the fins 121 on the rear side of the lamp housing 120, it can be taken away by the rapidly flowing air current. And the rapidly flowing air current can stir the air around the entire floodlight, making the surrounding air constantly flow, which helps to improve the heat dissipation effect of the floodlight, and further ensures that the floodlight body 100 can work stably in a place with a relatively high temperature (the floodlight body 100 is not suitable for working in an outdoor unobstructed environment).

[0038] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
