Abstract

The FET heat sink can be closely attached to the converter case to dissipate heat generated from the FET installed inside the converter that supplies the LED module to the outside. The FET which generates a lot of heat inside the luminaire converter is attached to the FET heat sink by the FET fixing plate, and the heat conduction tape attached to the outer surface of the FET heat sink allows the FET heat sink to contact the converter case well. . The FET heat sink is in close contact with the converter case by a close plate spring coupled to the sliding groove formed on the inner upper surface. Since the contact plate spring has elasticity, the FET heat sink is pushed toward the converter case, so the FET heat sink is tightly adhered to the converter case, so the FET heat sink transfers the heat absorbed from the FET to the converter case to be quickly released to the outside. The heat dissipation effect can be obtained.

FET heat sinks 40 are provided on both side surfaces of the converter case 12. FET 20 is installed on one side of the FET heat sink 40. The FET 20 is fixed to the FET heat sink 40 by the fixing plate 22. Since the FET heat sink 40 is located between the FET 20 and the converter case 12, heat generated in the FET 20 is absorbed into the converter case 12 through the FET heat sink 40 and is externally provided. The heat generated by the FET 20 is discharged to the outside. At this time, in order for the FET heat sink 40 to transfer heat to the converter case 12 smoothly, the FET heat sink 40 should be in close contact with the converter case 12, and the FET heat sink 40 is the converter case ( If it is not closely attached to 12), heat is not smoothly transferred, and heat of the FET 20 is not well discharged to the outside, which causes the failure of the converter 10 while degrading the performance of the FET 20.

Referring to FIGS. 3 to 5, first, an LED module (not shown) used for lighting or outdoor signage receives power applied from the outside through the converter 100. The converter 100 converts a high-voltage AC power applied from the outside into a constant low voltage suitable for the LED module and supplies the LED module to the LED module to smoothly perform the lighting function.

In the electronic component provided inside the converter 100, a lot of heat is generated and the heat generated from the electronic component is quickly discharged to the outside so that the converter 100 does not cause a failure. The converter case 110 constituting the converter performs a heat sink function for dissipating heat to the outside.

The inside of the converter case 110 is provided with a FET heat sink 120 for absorbing heat generated from the electronic component to discharge to the outside through the converter case (110). The FET heat sink 120 has a plate shape and is installed in the longitudinal direction on both inner sidewalls of the converter case 110. On one side of the FET heat sink 120, the FET 130 is installed by the FET fixing plate 132. The heat generated by the FET 130 is immediately absorbed by the FET heat sink 120, the FET heat sink 120 quickly releases the absorbed heat to the outside through the converter case 110. At this time, in order for heat to be smoothly transferred from the FET heat sink 120 to the converter case 110, the FET heat sink 120 and the converter case 110 should be in close contact with each other.

The contact plate spring 140 for pushing and pushing the FET heat sink 120 toward the converter case 110 so that the FET heat sink 120 and the converter case 110 can be closely adhered to the FET heat sink 120. Is installed.

The FET heat sink 120 is provided with a sliding coupling groove 122 to which the close spring 140 is coupled so that the close plate spring 140 may be installed in the FET heat sink 120.

The sliding coupling groove 122 is formed at a predetermined depth in the longitudinal direction of the FET heat sink 120 while positioned above the FET fixing plate 132. In this case, the sliding coupling grooves 122 are formed in the two FET heat sinks 120 respectively provided on both inner sidewalls of the converter case 110, and the sliding coupling grooves are formed in the two FET heat sinks 120, respectively. 122 is formed to correspond to each other.

The contact plate spring 140, which is an elastic body inserted into the sliding coupling groove 122, has a plate shape having a predetermined length and thickness. The close plate spring 140 is bent in both sides in the longitudinal direction to have a depressed ([]) shape. In addition, the insertion end portion 142 is bent in the outer direction in the entire length direction so that the insertion end portion 142 in the state in which both sides of the close plate spring 140 is bent.

Both ends of the contact plate spring 140 is bent to have the same direction as the entire longitudinal direction, and both ends of the contact plate spring 140 has one side edge to be smoothly coupled to the sliding coupling groove 122. It is rounded round. That is, since both ends of the close plate spring 140 is half rounded and half has an original state at a right angle, when the rounded portion of the close plate spring 140 is fitted into the sliding coupling groove 122, the close plate The spring 140 pushes and pushes the FET heat sink 120 having the sliding coupling groove 122 toward the converter case 110.

A heat conduction tape 150 is attached between the FET heat sink 120 and the converter case 110 so that the FET heat sink 120 is always in close contact with the converter case 110. Both surfaces of the heat conductive tape 150 are attached to the FET heat sink 120 and the converter case 110, so that the FET heat sink 120 and the converter case 110 may be in close contact with each other. Since the heat conductive tape 150 has a property of transferring heat well, the FET heat sink 120 performs a heat radiating function to transfer heat absorbed from the FET 130 to the converter case 110 well.
