Description

Technical Field

[0001] This utility model relates to the field of street lamp housing technology, specifically an integrated die-cast street lamp housing. Background Technology

[0002] Streetlights are lighting fixtures installed along roads to provide illumination. Their main purpose is to provide light for pedestrians and vehicles at night, ensuring traffic safety and convenience. Streetlights include the lamp housing, which is often also called the lamp head and is one of the main components of a streetlight, primarily used to support and fix the light source.

[0003] A search revealed that patent application number 202021915120.1 discloses a housing for a solar street light, comprising a profile tube, an end block, a first housing, a second housing, and a tail plate; the end block is sealed and fixed at the front opening of the first housing; the profile tube comprises two, which are arranged parallel to each other and respectively fixed on the left and right sides of the first housing; the left and right ends of the rear side of the end block are detachably fixed to the front ends of the two profile tubes; the second housing is located between the two profile tubes and can slide back and forth, and is located on the rear side of the first housing; the tail plate is sealed and fixed at the rear opening of the second housing; the left and right ends of the front end of the tail plate are detachably fixed to the rear ends of the two profile tubes.

[0004] Although the solar street light's housing facilitates battery replacement and improves work efficiency through the design of the second housing and two profile tubes, the housing does not easily dissipate internal heat, which can easily lead to damage to the internal light panel due to overheating.

[0005] Therefore, we propose an integrated die-cast street light housing. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an integrated die-cast street light housing, which solves the problem that existing devices are not good at dissipating heat from inside the housing, which can easily lead to damage to the internal light panel due to overheating.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an integrated die-cast street light housing, including a die-cast housing, wherein a first groove is provided on the bottom surface of the die-cast housing, and a lamp plate groove for mounting a lamp plate is provided in the middle of the bottom surface of the first groove.

[0008] A connecting part is provided in the middle of the right side of the top surface of the die-cast housing. A convex shell connected to the lamp plate slot is provided on the side of the top surface of the die-cast housing near the connecting part. A wire hole is opened in the middle of the side wall of the convex shell near the connecting part. A heat dissipation fin is fixedly installed on the side of the top surface of the die-cast housing away from the connecting part in a linear array. The heat dissipation fin has an arc-shaped cross section and is made of copper.

[0009] Preferably, a second connecting hole is provided at the four corners and the center of each edge of the top surface of the die-cast housing, and a transparent baffle is provided below the die-cast housing. The top surface of the transparent baffle is provided with a third connecting hole that corresponds to the second connecting hole. The transparent baffle can protect the lamp plate inside the lamp plate slot.

[0010] Preferably, the outline of the transparent baffle is the same as the outline of the first groove, the transparent baffle is located inside the first groove, and the transparent baffle is detachably installed on the bottom surface of the die-cast housing by bolts and nuts. The bolts pass through the second connecting hole and the third connecting hole and cooperate with the nut to fix the transparent baffle inside the first groove, so as to facilitate the removal of the transparent baffle from the inside of the first groove.

[0011] Preferably, the bottom surface of the first groove is provided with a first sealing groove and a second sealing groove located on the outer ring of the lamp plate groove. The first sealing groove is located on the outer ring of the second sealing groove. The first sealing groove and the second sealing groove are respectively movably fitted with a first sealing strip and a second sealing strip. The top surface of the transparent baffle is in close contact with the bottom surface of the first sealing strip and the second sealing strip. The first sealing strip and the second sealing strip can increase the sealing between the transparent baffle and the first groove, thereby preventing external rainwater from entering the interior of the lamp plate groove, which is beneficial to protecting the lamp plate inside the lamp plate groove.

[0012] Preferably, an annular sealing ring is fixedly fitted on the inner wall of the wire hole. The annular sealing ring is made of silicone. The wire connecting the lamp plate groove passes through the inner ring of the annular sealing ring. The surface of the wire is squeezed by the inner wall of the annular sealing ring, which can increase the sealing between the annular sealing ring and the wire and prevent external rainwater from entering the interior of the lamp plate groove through the gap between the annular sealing ring and the wire.

[0013] Preferably, the connecting part includes an arc-shaped plate and a side plate. The arc-shaped plate has side plates on both its front and rear sides. The arc-shaped plate and the side plates are fixedly installed in the middle of the right side of the top surface of the die-cast housing. The top surface of the side plate has a first connecting hole. The die-cast housing, the convex shell, and the connecting part are integrally die-cast structures. The arc-shaped plate, the side plates, and the first connecting hole facilitate the connection of the die-cast housing to the lamp post of the street light using a nut.

[0014] This utility model provides an integrated die-cast street light housing. It has the following advantages:

[0015] 1. This integrated die-cast street light housing absorbs the heat generated by the lamp panel inside the lamp panel slot during illumination through the die-cast housing, and dissipates the heat inside the die-cast housing to the air through heat dissipation fins. This can increase the heat dissipation efficiency of the lamp panel, thereby avoiding damage caused by excessive heat of the lamp panel. By accommodating the excess length of wires and controllers connected to the lamp panel, it is simple and convenient to use. It solves the problem that existing devices are not easy to dissipate the heat inside the housing, which can easily lead to damage to the lamp panel inside due to overheating.

[0016] 2. The integrated die-cast street light housing, through the cooperation of the first sealing strip and the second sealing strip set inside the first sealing groove with the transparent baffle, can increase the sealing between the transparent baffle and the first groove. At the same time, by the inner wall of the annular sealing ring pressing the outer surface of the wire connected to the light panel, the sealing between the annular sealing ring and the wire can be increased, thereby preventing rainwater from the external environment from entering the interior of the light panel groove and causing short circuit damage to the light panel, thus improving the protection effect of the light panel.
