Technical Field
[0001] This utility model relates to the field of street light technology, specifically a high-brightness photovoltaic street light. Background Technology
[0002] Photovoltaic streetlights utilize the photoelectric conversion principle of photovoltaic cells to convert solar energy into electrical energy, which is stored in batteries. The stored electrical energy is then supplied to LED lights to provide illumination. Photovoltaic streetlights use natural light sources and do not consume electricity. Compared to traditional streetlights, photovoltaic streetlights significantly save energy, reduce energy waste, and decrease the cost of cable laying and maintenance. Photovoltaic streetlights have a wide range of applications, including urban roads, parks, squares, schools, factories, and other places. In existing technologies, the LED panels of photovoltaic streetlights generate a lot of heat during the lighting process. This heat cannot dissipate quickly inside the streetlight casing, which can easily lead to overheating of the LED chips, thus affecting the luminous efficiency and lifespan of the LED beads. Summary of the Invention

This heat cannot be quickly dissipated inside the street light casing, which can easily lead to excessively high temperatures in the LED chips, thereby affecting the luminous efficiency and lifespan of the LED beads.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-brightness photovoltaic street light, comprising an aluminum profile housing, a cast aluminum upper shell inserted into the top of the aluminum profile housing, a cast aluminum lower shell inserted into the bottom of the aluminum profile housing, a fixing groove provided on the front side of the aluminum profile housing, a lamp plate connected to the inner wall of the fixing groove, a lens fixedly connected to the front side of the aluminum profile housing, the lamp plate being fixedly connected to the lens, grooves equidistantly provided on both sides of the outer wall of the aluminum profile housing, and heat dissipation plates equidistantly provided on the back side of the aluminum profile housing.
[0005] Preferably, a clamp is provided on one side of the cast aluminum lower shell, and a fixing hole is provided on the side of the cast aluminum lower shell and the clamp that are close to each other.

It offers the following advantages: This high-brightness photovoltaic street light, through the cooperation of an aluminum profile housing, a cast aluminum upper shell, a cast aluminum lower shell, a fixing groove, a lamp panel, a lens, grooves, and a heat sink, uses a high thermal conductivity aluminum profile housing to fix the lamp panel. By providing heat sinks and grooves on the back and sides of the aluminum profile housing, the contact area between the aluminum profile housing and the external air is increased, further enhancing the heat dissipation effect. The heat generated by the lamp panel can be quickly conducted to the external environment through the aluminum profile housing, grooves, and heat sink, effectively preventing the photovoltaic street light from overheating during prolonged operation. This avoids the lamp panel's excessive temperature affecting the luminous efficiency and lifespan of the LED beads, thus helping to extend the lifespan of the high-brightness photovoltaic street light.
[0010] By using the interlocking mechanism between the cast aluminum lower shell, clamp, fixing hole, first fixing bolt, and protrusion, the fixing rod of the street light pole is inserted into the fixing hole between the cast aluminum lower shell and the clamp, and the first fixing bolt is tightened. At the same time, the protrusion increases the structural strength of the clamp, which clamps and secures the fixing rod of the street light pole. This allows for quick connection and stable fixation of the photovoltaic street light to the street light pole, preventing the street light from swaying under wind force. This helps to further improve the stability and safety of the street light after installation. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] In existing technologies, the LED panels of photovoltaic streetlights generate a lot of heat during the lighting process. This heat cannot be dissipated quickly inside the streetlight housing, which can easily lead to excessively high temperatures in the LED chips, thereby affecting the luminous efficiency and lifespan of the LED beads.
[0020] In view of this, the present invention provides a high-brightness photovoltaic street light. Through the cooperation of an aluminum profile housing, a cast aluminum upper shell, a cast aluminum lower shell, a fixing groove, a lamp panel, a lens, grooves, and a heat sink, the lamp panel is fixed using an aluminum profile housing with high thermal conductivity. By providing heat sinks and grooves on the back and sides of the aluminum profile housing, the contact area between the aluminum profile housing and the external air is increased, further enhancing the heat dissipation effect of the aluminum profile housing. The heat generated by the lamp panel is quickly conducted to the external environment through the aluminum profile housing, grooves, and heat sink, effectively preventing the photovoltaic street light from overheating due to prolonged operation. This avoids the lamp panel's excessive temperature affecting the luminous efficiency and lifespan of the LED beads, thereby extending the lifespan of the high-brightness photovoltaic street light.

The lens 6 is made of high light transmittance material, which can effectively improve the light transmittance and reduce light loss, thereby improving the lighting brightness and uniformity of the street light. The assembly of the aluminum profile housing 1, cast aluminum upper housing 2, cast aluminum lower housing 3, fixing groove 4, lamp board 5, lens 6, groove 7, and heat sink 8 utilizes the high thermal conductivity of the aluminum profile housing 1 to fix the lamp board 5.

The heat generated by the lamp board 5 is quickly conducted to the external environment through the aluminum profile housing 1, grooves 7, and heat sink 8, effectively preventing the photovoltaic street light from overheating due to prolonged operation. This avoids the lamp board 5's excessive temperature affecting the luminous efficiency and lifespan of the LED beads, thereby extending the lifespan of the high-brightness photovoltaic street light.

The cast aluminum upper shell 2 and the cast aluminum lower shell 3 are connected and fixed to the aluminum profile shell 1 through the slot structure and the long screw. The two ends are tightened with the anti-loosening nut 13 and two ordinary nuts respectively to prevent loosening, thereby improving the connection stability between the cast aluminum upper shell 2 and the cast aluminum lower shell 3 and the aluminum profile shell 1, and improving the overall strength of the photovoltaic street light shell structure.
