Description

Technical Field

[0001] This utility model relates to the field of LED street light technology, and in particular to a wide-angle LED street light. Background Technology

[0002] Traditional LED streetlights mount LED panels on a single plane, with the light primarily illuminating directly below the LED light source. However, the light poles are typically 12-20 meters high, and the spacing between them is generally 35-40 meters. This results in a long, dark section of road between adjacent poles, creating an alternating pattern of bright and dark areas that poses a safety hazard for nighttime pedestrians. Therefore, there is a need to research and develop an LED streetlight with a wider beam angle. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned problems existing in the prior art and to provide a wide-angle LED street light.

[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution: A wide-angle LED street light includes an aluminum lamp housing, an aluminum mounting base, and a light-transmitting lamp cover. The aluminum mounting base and the light-transmitting lamp cover are both installed at the bottom of the aluminum lamp housing. The bottom of the aluminum mounting base has multiple parallel support surfaces arranged sequentially from bottom to top. An LED light panel is installed on each support surface. The LED light panel and the aluminum mounting base are both covered by the light-transmitting lamp cover. A bevel is provided between any two adjacent support surfaces. A mirror reflective film is pasted on the bevel. The angle between the bevel and the adjacent support surface above it is 100° to 120°.

[0005] Preferably, the angle between the inclined surface and the adjacent support surface above it is 110°.

[0006] Preferably, the aluminum mounting base is in the shape of a boss.

[0007] Preferably, the aluminum mounting base has multiple internal heat dissipation fins fixedly attached to it.

[0008] Preferably, a cylindrical aluminum tube is fixed to one side of the aluminum lamp housing, and the aluminum tube is connected to the interior of the aluminum lamp housing.

[0009] Preferably, the outer side of the aluminum lamp housing is provided with a plurality of evenly distributed external heat dissipation fins.

[0010] Preferably, multiple support columns are fixed to the top of the aluminum lamp housing, and a plastic sunshade is installed on the top of the support columns to reduce sunlight from shining on the aluminum lamp housing.

[0011] Preferably, the bottom end of the aluminum lamp housing is provided with a downwardly extending flange, and the bottom end of the flange is lower than the bottom edge of the light-transmitting lampshade.

[0012] The beneficial effects of this utility model are as follows: LED light panels are installed on multiple support surfaces arranged sequentially from bottom to top and parallel to each other, and a mirror reflective film is pasted on the inclined surface between adjacent support surfaces. Part of the light emitted by the LED light panels directly illuminates the road surface, and the other part is reflected to the side of the LED street light through the mirror reflective film, thereby increasing the illumination angle range of the LED street light and enabling the light emitted by the LED street light to illuminate the middle of the road section between two adjacent light poles, thus weakening the alternation of black and white on the road.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] like Figures 1 to 5 As shown, a wide-angle LED street light 100 includes an aluminum lamp housing 1, a boss-shaped aluminum mounting base 2, and a light-transmitting lamp cover 3. The aluminum mounting base 2 and the light-transmitting lamp cover 3 are both installed at the bottom of the aluminum lamp housing 1 with screws. A round aluminum tube 11 is fixed to one side of the aluminum lamp housing 1, and the aluminum tube 11 is connected to the inside of the aluminum lamp housing 1.

[0016] When this wide-angle LED street light 100 is installed on the light pole, the aluminum tube 11 is fitted onto the light pole, and a fastening bolt is screwed into the nut at the bottom of the aluminum tube 11, so that the tail end of the fastening bolt abuts or is screwed into the light pole, thereby connecting and fixing the aluminum tube 11 to the light pole.

[0017] The bottom of the aluminum mounting base 2 has four parallel support surfaces 21 arranged sequentially from bottom to top. Each support surface 21 is equipped with an LED light board 4. The LED light board 4 is installed on the support surface 2 using foam adhesive or self-tapping screws. Both the LED light board 4 and the aluminum mounting base 2 are covered by a light-transmitting lampshade 3.

[0018] An LED driver 7 is installed in the aluminum lamp housing 1, and the LED driver 7 is connected to the LED lamp board 4 by wires. A wire through hole is opened on each support surface 21 of the aluminum mounting base to facilitate the passage of the wires connecting the LED driver 7 and the LED lamp board 4.

[0019] A beveled surface 22 is provided between any two adjacent support surfaces 21. A mirror reflective film 5 is attached to the beveled surface 22. The angle between the beveled surface 22 and the adjacent support surface 21 above it is 100~120°.

[0020] Multiple internal heat dissipation fins 23 are fixed in the aluminum mounting base 2, and several evenly distributed external heat dissipation fins 12 are provided on the outer side of the aluminum lamp housing 1. The internal heat dissipation fins 23 dissipate the heat in the aluminum mounting base 2 to the aluminum lamp housing 1, and the heat in the aluminum lamp housing 1 is dissipated to the air around the wide-angle LED street light 100 through the aluminum lamp housing 1 and the external heat dissipation fins 12, thereby reducing the internal temperature of the wide-angle LED street light 100.

[0021] Multiple support columns 13 are fixed to the top of the aluminum lamp housing 1, and a plastic sunshade 6 is installed on the top of the support columns 13 to reduce sunlight from shining on the aluminum lamp housing 1.

[0022] The bottom of the aluminum lamp housing 1 is provided with a downwardly extending flange 14, and the bottom of the flange 14 is lower than the bottom edge of the light-transmitting lamp cover 3, so that the flange 14 acts as a drip line to prevent liquid on the outside of the aluminum lamp housing 1 from flowing into the light-transmitting lamp cover 3.

[0023] A sealing gasket is sandwiched between the light-transmitting lampshade 3 and the aluminum lamp housing 1 to prevent moisture from entering the light-transmitting lampshade through the gap between the light-transmitting lampshade and the aluminum lamp housing 1; sealant is applied between the aluminum tube 11 and the lamp post to prevent rainwater from entering the aluminum tube. Other gaps or holes are sealed using the same sealing method as described above, which involves installing sealing gaskets or applying sealant.

[0024] like Figure 6As shown, the angle between the inclined surface 22 of the wide-angle LED street light and the adjacent support surface 21 above it is 110°. The wide-angle LED street light is installed on two light poles with a height of 12 meters and a spacing of 40 meters. At this time, the angle between the inclined surface 22 and the horizontal plane is 20°. When the wide-angle LED street light is working, the light is reflected by the mirror reflective film on the inclined surface and then shines on the ground. According to the trigonometric function, the farthest distance the light shines on the ground is X = 12 * cot20°. Through calculation, X is approximately equal to 32.97 meters. Therefore, the middle part between two adjacent light poles can be covered by the reflected light from the LED street lights on the two light poles, thereby improving the light brightness in the middle area between two adjacent light poles.
