Description

Technical Field

[0001] This utility model belongs to the field of street light technology, specifically relating to a high-efficiency LED street light module. Background Technology

[0002] Existing streetlights mainly use LED streetlight modules, among which the 3030 type LED chips are the most frequently used. The luminous efficacy of the 3030 type is the highest at 160~170 lm / W. To further improve the luminous efficacy, 5050 type LED chips are needed. However, the production cost of using 5050 type LED chips is very high, and because the 5050 type LED chips have a larger light-emitting surface, their heat dissipation performance is weaker. Therefore, the streetlight cover needs to enhance the heat dissipation function, which will significantly increase the cost for manufacturers. Therefore, in order to improve the luminous efficacy, it is necessary to improve the existing 3030 type structure to further enhance its luminous efficacy. Utility Model Content

[0003] The purpose of this utility model is to solve the problems in the background technology and provide a high-efficiency LED street light module. Based on the 3030 type specification, the street light module has redesigned the structure of the street light and adopted 112 3030 type LED beads, which can significantly improve the luminous efficiency of the street light.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A high-efficiency LED street light module includes a heat sink, a lamp cover, a lamp board, and reflective paper. Heat dissipation fins are machined on one side wall of the heat sink. The lamp cover is mounted on the other side wall of the heat sink. A receiving cavity is machined on the side wall of the lamp cover closest to the heat sink. A sealing ring that tightly contacts the heat sink is installed on the side wall of the lamp cover. A lamp board is mounted on the heat sink inside the lamp cover, and multiple 3030 type LED beads are mounted on the lamp board. A lens corresponding to each LED bead is mounted on the lamp cover. The lens and lamp cover are integrally formed. The reflective paper is laid between the lamp board and the lens, and clearance openings corresponding to the positions of each LED bead and screw holes are machined on the reflective paper.

[0006] The lampshade has mounting openings that correspond one-to-one with the positions of the lenses. The lenses are fixed in a convex manner at the mounting openings, and a gap is left between the inner wall of the lens and the inner wall of the lampshade. The reflective paper concentrates the light from the LED beads into the gap.

[0007] The radiator has a wire hole in the middle, and a waterproof wire is installed in the wire hole. The waterproof wire is fixed on the radiator and connected to the positive and negative terminals of the lamp board.

[0008] The high-efficiency LED street light module provided by this utility model has the following beneficial effects:

[0009] (1) By setting up a high-efficiency LED street light module with a lens and 3030 LED beads, and with the help of reflective paper, the diffused light can be gathered between the lamp panel and the lens and then passed through the lens, so that the luminous efficacy of the 3030 LED beads can be increased from 160~170Lm / W to 220Lm / W, and the overall luminous efficacy of the street light can be 195~205Lm / W. In this way, the lighting effect that high-power LED beads can achieve is achieved with low-power LED beads, and at the same time, there is no need to redesign the heat dissipation of the street light.

[0010] (2) By setting up an installation port and molding the lens and lampshade together, the modularity of the street light can be improved on the one hand, and the spacing between the LED beads and the lens can be guaranteed on the other hand, thus ensuring the light efficiency.

[0016] like Figures 1-3As shown, the high-efficiency LED street light module provided in this embodiment includes a heat sink 1, a lamp cover 2, a lamp board 3, and reflective paper 4. Heat dissipation fins are machined on one side wall of the heat sink 1. A wire hole 10 is machined in the middle of the heat sink 1, and a waterproof wire 11 is installed inside the wire hole 10 and fixed to the heat sink 1. The lamp cover 2 is installed on the other side wall of the heat sink 1. A receiving cavity is machined on the side wall of the lamp cover 2 closest to the heat sink 1. A sealing ring 9 is installed on the side wall of the lamp cover 2 to tightly contact the heat sink 1. A lamp board 3 is installed on the heat sink 1 inside the lamp cover 2. The waterproof wire 11 is connected to the positive and negative terminals of the lamp board 3. A reflective paper 4 is installed on the lamp board 3. Two 3030 type LED beads 6, 112 LED beads 6 are arranged in six columns, each column is arranged sequentially, avoiding the position of screw holes. The lamp cover 2 is equipped with a lens 7 corresponding to each LED bead 6. The lamp cover 2 is machined with mounting holes 8 corresponding to the positions of the lenses 7. The lenses 7 are fixed in a convex manner at the mounting holes 8. The lenses 7 and the lamp cover 2 are integrally formed. The reflective paper 4 is laid between the lamp board 3 and the lenses 7. A gap is left between the inner wall of the lens 7 and the inner wall of the lamp cover 2. The reflective paper 4 concentrates the light of the LED beads 6 into the gap. The reflective paper 4 is machined with avoidance holes 5 corresponding to the positions of each LED bead 6 and screw holes.

[0017] The principle of this utility model is:

[0018] After the light panel 3 is powered on, the light emitted by the 3030 LED beads 6 is transmitted through the lens 7, and the scattered light is refocused on the lens 7 by the reflective paper 4 and transmitted through the lens 7. This can achieve the effect of focusing the light, so that the lighting effect of the 3030 LED beads 6 is close to that of the 5050 LED beads 6. Moreover, the heat dissipation of the light panel 3 is still provided by the 3030 LED beads 6, so there is no need to redesign the heat dissipation of the street light.
