Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to an LED lamp power drive device for a high-efficiency heat dissipation guide rail. Background Art

[0002] The power driver provides power to the lamp. In terms of LED lamps for guide rails, the traditional power driver is assembled with the guide rail in the form of a power driver box to provide power for the LED lamp installed on the guide rail. When installing and using, the guide rail is first installed on the ceiling or wall, and then the power driver box is installed on the guide rail in a fixed connection manner, and the power connector on the power driver box is electrically connected to the conductive plate in the guide rail, thereby providing power for the LED lamp on the guide rail to emit light.

[0004] 1. After the traditional power drive box is installed on the guide rail, the length of its power cord usually needs to be cut very short. If the power cord is too long, it can only be arranged in the cavity of the power drive box in a messy way, which poses a great safety hazard and is not conducive to the heat dissipation of the internal power module;

[0005] 2. The power module inside the power driver box will generate heat when working, but the traditional power driver box is usually designed to be relatively closed, and there are messy power cords arranged in the cavity, which makes the space in the cavity more dense, making it easier for the power module to overheat, causing safety accidents and damaging power driver devices, lamps and other equipment.

[0006] 3. The traditional power drive box lacks the snap-on structure and positioning structure when installed with the guide rail, which makes it impossible to quickly snap-on install and position the power drive box when it is installed on the guide rail, resulting in low installation efficiency and insufficient installation stability of the power drive box.

[0040] The high-efficiency heat dissipation guide rail LED lamp power drive device comprises a bottom shell 10 and a connection cover 20, wherein the bottom shell 10 has a cavity 101 with an opening upward, a power module 30 is installed in the cavity 101, and the connection cover 20 is detachably or fixedly covered on the cavity 101 of the bottom shell 10. By covering the connection cover 20 on the cavity 101, the power module 30 in the cavity 101 can be basically fixedly installed. After the connection cover 20 is covered and connected with the bottom shell 10, the power drive device as a whole is roughly in the shape of a strip box. When installing the power drive box, the top of the connection cover 20 is detachably assembled with the guide rail a, and then the power drive box is detachably installed on the guide rail a, providing power for the LED lamp on the guide rail a to emit light.

[0041] The connecting cover 20 has a cover convex portion 201 and a cover concave portion 202, both of which are arranged at the top of the connecting cover 20, and the cover convex portion 201 and the cover concave portion 202 are arranged at different sides of the top of the connecting cover 20. For example, in the length direction of the connecting cover 20 and the direction of connection with the guide rail a, the cover convex portion 201 is arranged on one side of the length direction of the connecting cover 20, and the cover concave portion 202 is arranged on the other side of the length direction of the connecting cover 20.

[0042] The connecting cover 20 is detachably connected to the guide rail a through the cover convex part 201. In addition, the cover convex part 201 is provided with a power connection hole 2014 that passes through the top and bottom of the connecting cover 20. The connecting cover 20 and the bottom of the cover convex part 201 are provided with a power connector 32 that is electrically connected to the power module 30. The plug piece of the power connector 32 passes through the power connection hole 2014 upward and extends out of the surface of the cover convex part 201.

The wiring seat 31 is electrically connected to the power module 30 through the wires, and the wires connected to the wiring seat 31 can be neatly arranged in the setting direction of the wire storage groove 2021.

[0044] In this way, the cover recess 202 of the connecting cover 20 is provided with a wire storage groove 2021 in the wire routing direction, and the wires are arranged and arranged through the wire storage groove 2021; compared with the previous implementation method of simply hiding the wires in the cavity 101 of the power drive box, the present application arranges the wires in the wire storage groove 2021 of the connecting cover 20, avoiding the stacking of wires in the cavity 101 of the bottom shell 10, which causes the air in the space of the power module 30 to be blocked, thereby making the direction of the wires more organized, improving the heat dissipation effect of the power drive device, and reducing safety hazards. Moreover, longer wires can also be hidden, without the need to cut the wires, which is convenient for subsequent maintenance and avoids waste of resources.

[0045] Preferably, a plurality of heat dissipation holes 2011 are provided on the cover convex portion 201, and the plurality of heat dissipation holes 2011 are generally strip-shaped, and the strip-shaped heat dissipation holes 2011 are extended in the length direction of the connection cover 20, and the plurality of heat dissipation holes 2011 are connected to the inside of the bottom shell 10, so as to allow the power module 30 to circulate air and dissipate heat. In this way, compared with the closed design of the previous power drive box, by providing a plurality of heat dissipation holes 2011 on the connection cover 20, the air in the cavity 101 can be circulated outward, thereby further improving the heat dissipation effect of the power drive device.

[0046] In the embodiment of the present application, the inner wall of the cavity 101 of the bottom shell 10 is provided with a supporting convex edge 102, which is integrally formed on the inner wall of the cavity 101, and the supporting convex edge 102 is arranged on the inner wall of the cavity 101 along the circumference of the bottom shell 10, so as to form a supporting convex edge 102 arranged at a certain height and in a horizontal direction on the inner wall of the cavity 101. The bottom edge of the connecting cover 20 is provided with a right-angled cover body edge groove 203, and the cover body edge groove 203 is arranged around the edge of the connecting cover 20, so that the bottom edge of the connecting cover 20 forms a ring-shaped cover body edge groove 203. When installing the connecting cover 20, through the cooperation of the cover body edge groove 203 and the supporting convex edge 102, the four edges of the connecting cover 20 can be roughly supported and connected, so that the connecting cover 20 is more stably and accurately covered on the bottom shell 10.

[0047] Moreover, a plurality of vertically extending connection posts 103 are also provided on the inner wall of the cavity 101. The plurality of connection posts 103 are arranged along the direction in which the support flange 102 is provided.

[0048] In the embodiment of the present application, a plurality of support platforms 104 are further provided on the inner wall of the cavity 101 of the bottom shell 10. Specifically, a support platform 104 is provided on the inner wall of the cavity 101 at both ends of the bottom shell 10.

Similarly, the snap-fit ​​component 11 is also arranged corresponding to the positioning notch 105 at the bottom of the cavity 101. The outer side of the snap-fit ​​component 11 is arranged in an arc-shaped surface. Since the bottom of the positioning notch 105 and the support platform 104 are on the same horizontal plane, the snap-fit ​​component 11 can also be supported on the bottom of the positioning notch 105, and the outer side surface of the snap-fit ​​component 11 can be exposed to the outer surface of the bottom shell 10 through the positioning notch 105.
