Description

Technical Field

[0001] This utility model relates to the field of driver power supplies, and in particular to heat dissipation housings for LED driver power supplies. Background Technology

[0002] LED lights, also known as light-emitting diodes, are solid-state semiconductor devices that convert electrical energy into visible light. Compared to traditional incandescent and fluorescent lamps, LED lights have many advantages. LED lights have a much higher luminous efficiency than traditional lighting equipment, converting more electrical energy into light energy, thus being more energy-efficient. The lifespan of LED lights can typically reach tens of thousands of hours, far exceeding that of incandescent and fluorescent lamps, reducing replacement frequency and maintenance costs. LED lights do not contain harmful substances such as mercury, and will not pollute the environment after disposal. LED lights have a very fast response speed, capable of instantly lighting up or turning off, and can be frequently switched on and off or have their brightness adjusted without damage. Therefore, they are becoming increasingly popular in the lighting market.

[0003] The driver power supply for LED lights is a power converter that transforms the power supply into a specific voltage and current to drive the LED light to emit light. Existing LED driver power supplies are usually integrated with the LED light body.

[0004] LED driver power supplies generate heat when operating. The housing of an LED driver power supply usually has several heat sinks and cooling fans on its surface to cool it down. After long-term use, a lot of dust will stick to the surface of the heat sinks and cooling fans. Dust will seriously affect the heat dissipation efficiency, so it is necessary to clean it regularly. The heat sinks and cooling fans in the housing of existing LED driver power supplies are usually fixedly connected to the housing, which is not convenient for cleaning dust. Utility Model Content

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An LED driver power supply heat dissipation housing includes a housing and heat sinks. The housing contains an electrical control cavity for mounting the main control circuit board. Several heat sinks are evenly distributed on the sidewalls of the housing. A cooling fan is located at the end of the housing furthest from the opening of the electrical control cavity, aligned with the heat sinks. An annular mounting groove is provided on the sidewall of the housing, within which a heat sink base is installed. Several heat sinks are disposed on the surface of the housing. A positioning slot is provided on the surface of the housing, within which a fan base is installed. The cooling fan is mounted at the end of the fan base furthest from the housing. A protective cover is provided on the outer side of the cooling fan, with its edge connected to the edge of the fan base. A limit slider is provided on the sidewall of the fan base, connected to the fan base by a spring. A limit slot is provided on the inner wall of the positioning slot, into which the limit slider can be inserted. A reset button is provided within the limit slot, extending from the end furthest from the fan base to the surface of the housing. Contact points are provided on the bottom surface of the positioning slot and the surface of the fan base.

[0008] Furthermore, the side wall of the fan base is provided with a positioning groove, the side wall of the positioning slot is provided with a positioning boss, the positioning groove and the surface of the positioning boss slide in contact, the limiting slider is provided in the positioning groove, and the limiting slot is provided on the surface of the positioning boss.

[0009] Furthermore, a dust filter is provided at one end of the protective cover near the heat sink, and the dust filter is connected to the protective cover via a connecting ring.

[0010] Furthermore, the surface of the housing is provided with a panel groove for mounting the main control switch.

[0011] Furthermore, a light source bracket is provided inside the electrical control cavity, and the edge of the light source bracket is connected to the side wall of the electrical control cavity by bolts. The light source bracket is provided with fixing screw holes.

[0012] Furthermore, the end of the housing away from the cooling fan is provided with a threaded interface for mounting a lampshade.

[0013] Furthermore, the heat sink is uniformly and vertically arranged on the surface of the heat sink base around the axis of the housing.

[0014] Compared with the prior art, the advantages of this utility model are as follows: It is equipped with an annular mounting groove and a positioning slot. The heat sink is mounted on the heat sink base, which is detachably mounted in the annular mounting groove. The cooling fan is detachably connected to the housing via the fan base. The heat sink base is slidably connected to the annular mounting groove. After the fan base is inserted into the positioning slot, the limiting slider is inserted into the limiting slot, fixing the fan base in the positioning slot. The protective cover presses against the surface of the heat sink base, fixing it in the annular mounting groove. When cleaning the heat sink and cooling fan is required, pressing the reset button pushes the limiting slider, causing it to disengage from the limiting slot. The fan base is then removed from the positioning slot. The heat sink base can then be pulled out from the annular mounting groove towards the positioning slot, allowing for comprehensive dust removal and cleaning of the heat sink and cooling fan, making dust removal and cleaning more convenient.
