Description

Technical Field

[0001] The utility model relates to the technical field of lamp controllers, in particular to a high-heat dissipation integrated solar controller. Background Art

[0002] The structure of a solar street light primarily consists of a lamp body and a controller. In existing lamp designs, the driver board and controller are integrated onto a single circuit board and then mounted inside the housing. The entire housing cavity is then sealed with thermally conductive adhesive to provide a waterproof and moisture-proof seal. Heat generated by the circuit board is then transferred to the housing via the adhesive for dissipation. While this controller design simplifies the circuit board structure and assembly by integrating the driver board and controller onto the same board, using thermally conductive adhesive to dissipate heat from the circuit board is inefficient and requires a large amount of adhesive. Furthermore, since the circuit board is coated in thermally conductive adhesive, damage to the circuit board is impossible to repair. Utility Model Content

[0010] A retaining ring is provided on the sensor; one end of the sensor passes through the second positioning hole; the retaining ring is pressed against the inner wall of the shell; the end of the sensor extending out of the shell is covered with a pressure ring and a sealing ring; the inner wall of the pressure ring is provided with an internal thread matching the external thread; after the internal thread is threadedly connected to the external thread, the pressure ring presses the sealing ring against the outer wall of the shell.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0026] The sensor 5 is essentially the same as that of the prior art, so it is not described in detail here. The sensor 5 is used to sense external signals and generate signals to turn on the lamp. The outlet 202 is used to connect wires. The driver circuit board 2 and the control circuit board 3 are essentially the same as those of the prior art, so it is not described here in detail here. The only difference is that the driver circuit and the control circuit are separated on different boards and processed separately.

[0027] The driver circuit board 2 is connected to the control circuit board 3 via wires. The wires of the control circuit board 3 are led out through the glue potting frame 404 and the wire outlet hole 401. Because the glue potting frame 404 is filled with glue, the wire outlet hole 401 is sealed effectively. The glue potting of the side surface of the glue potting frame 404 only needs to seal the cross-section of the glue potting frame 404, greatly reducing the amount of glue used. The driver circuit board 2, which mainly generates heat, is directly attached to the heat dissipation base plate 1 to dissipate heat, improving heat dissipation efficiency.

[0028] As a preferred embodiment of the present invention, a plurality of support platforms 403 are provided on the inner bottom wall of the housing 4; a clamping block 406 is provided on both the left and right inner side walls of the housing 4; the driving circuit board 2 is clamped between the clamping block 406 and the support platform 403;

[0029] When the driver circuit board 2 is inserted from the open end face of the housing 4, after the driver circuit board 2 squeezes the wedge-shaped surface of the clamping block 406, the plastic deformation of the housing 4 allows the driver circuit board 2 to pass through the clamping block 406 smoothly. Finally, the driver circuit board 2 is clamped on the supporting platform 403 by the clamping block 406, preventing the driver circuit board 2 from shaking inside the housing 4.

[0030] As a preferred embodiment of the present invention, a countersunk hole 402 is provided on the shell 4; a threaded hole 102 is provided on the heat dissipation base plate 1; a bolt passes through the countersunk hole 402 and is threadedly connected in the threaded hole 102; the shell 4 is connected to the heat dissipation base plate 1 by the bolt, thereby realizing a detachable connection of the heat dissipation base plate 1 on the shell 4.

[0031] As a preferred embodiment of the present invention, a plurality of heat dissipation fins 101 are evenly distributed on a surface of the heat dissipation base plate 1 away from the driver circuit board 2; the heat dissipation fins 101 can increase the heat dissipation area of the heat dissipation base plate 1 and improve the heat dissipation efficiency of the driver circuit board 2.

[0034] The sensor 5 and the pressure ring 6 are fixed by a threaded connection and the sealing ring 7 is compressed, which can improve the waterproof effect and realize the detachable connection between the sensor 5 and the housing 4.

[0035] As a preferred embodiment of the present invention, the sensor 5 is provided with a switch hole 501; a power switch is disposed within the switch hole 501. The power switch is used to control the power on and off of the entire circuit, which is essentially the same as in the prior art. When the lamp is not used for an extended period of time or is being transported, turning off the power switch can prevent the control circuit from continuously drawing power, thereby reducing battery power consumption when not in use. A waterproof cover is provided over the switch hole 501 to prevent water from seeping in through the switch hole 501.

[0036] As a preferred embodiment of the present invention, the sensor 5 is any one of an infrared sensor and a photoelectric sensor.

[0037] As a preferred embodiment of the present invention, a first positioning through hole 301 is provided on the control circuit board 3; after the sensor 5 passes through the first positioning through hole 301 and the second positioning hole 405 in sequence, the retaining ring 503 presses the control circuit board 3 against the inner wall of the housing 4;

[0038] The control circuit board 3 is tightly connected with the retaining ring 503 of the sensor 5. The control circuit board 3 is installed at the same time as the sensor 5 is assembled, thereby improving the assembly efficiency of the controller.
