Description

{Radiating Structure For Lighting Equipment}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat dissipation structure for an illumination lamp capable of rapidly dissipating heat generated from a circuit board on which an LED is mounted to the outside.

Typically, the light is installed in the interior of the building, providing illumination light indoors at night. In addition, when an illumination light is applied to a streetlight, illumination light can be provided to a vehicle driving the road at night or a walker walking the street.

In recent years, LED street lamps using a light emitting diode (LED) lamp as a light source have been developed.

LED is a luminescence phenomenon that occurs when a voltage is applied to a semiconductor, and the light is emitted by using such an electroluminescence. These LEDs have the advantages of long lifetime, high efficiency of electric power because they are directly converted to light energy, low power consumption, and longer life than ordinary bulbs (lamps).

However, the LED lamp has a problem of shortening the lifetime of the LED lamp due to the occurrence of high temperature during the light emission. Accordingly, when the LED lamp is used as a light source in a street lamp, a heat dissipation structure capable of emitting heat generated from the LED lamp to the outside is applied and used.

In order to release the heat generated from the LED lamp, the LED lamp is installed separately from the LED lamp in the street lamp, which is formed integrally with the LED lamp.

Since most of the heat dissipating structures are formed in the form of a pin so as to achieve the air-cooling type, there is a problem that the heat radiation efficiency is limited.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, a lighting structure for a lighting fixture according to an embodiment of the present invention includes a base frame 10, a heat dissipation member 20, a globe 30, a fixing frame 40, And a waterproofing member 50.

The base frame 10 may be composed of a metal plate having a high thermal conductivity, in which the PCB 2 to which the LED 1 is electrically connected is detachably mounted on the lower surface. The base frame 10 may have an insertion groove 11 for inserting the PCB 2 and a screw tab 12 may be formed on the outer side of the insertion groove 11 and the insertion groove 11. Therefore, the PCB 2 can be inserted into the insertion groove 11 as the bolt B is screwed into the screw tab 12 of the insertion groove 11.

The heat dissipating member 20 is formed on the upper surface of the base frame 10 to dissipate the heat generated from the LED 1 upward. The heat dissipating member 20 may be arranged such that a plurality of heat dissipating plates composed of a metal having a high thermal conductivity are radially dispersed. The heat dissipating plates 20, which are the heat dissipating members 20, may be formed in a round shape by being cut at an outer edge of the upper part, or formed at an angle to be inclined or cut. That is, since the edge of the heat dissipating member 20 is formed in a round shape, it is possible to minimize interference with external components and prevent external components from being damaged.

The globe 30 may be formed of a hemispherical transparent material so as to diffuse light emitted from the LED 1 mounted on a lower portion of the base frame 10. That is, the light emitted from the LED 1 may be transmitted through the globe 30 and diffused to be illuminated over a wide range. The outward flange 31 may be formed on the rim of the globe 30.

The fixed frame 40 is detachably fixed to the lower portion of the base frame 10 while the rim of the globe 30 is extended. The fixing frame 40 is formed in the shape of a ring and is formed with an engaging step 42 for engaging the outward flange 31 of the globe 30 along the inner rim and corresponds to the screw tab 12 of the base frame 10 A through hole 41 penetrating vertically is formed.

Further, the fixing frame 40 can be detachably fastened to the base frame 10 by the fastening member 60. The fastening member 60 may be formed of a bolt threaded into the screw tab 12 of the base frame 10 through the through hole 41.

The waterproofing member 50 is composed of a rubber ring that waterproofs between the upper surface of the fixed frame 40 and the lower surface of the base frame 10. [ That is, when the fixing frame 40 is brought close to the base frame 10 by the fastening of the fastening member 60, the rubber ring as the waterproofing member 50 is compressed and water is sealed between the fixing frame 40 and the base frame 10 do.

4 and 5, the present invention includes an illumination case 100 in which an inner space is opened downward so that the radiation member 20 is received inward, (200) in which the base frame (10) is installed in a state where the base frame (30) is exposed. Therefore, the illumination frame 200 can be installed in the illumination case 100 with the base frame 10 mounted on the illumination frame 200. In addition, an entire glove 101 covering the lower portion of the illumination case 100 may be installed in the illumination frame 200.

The LED case 1 is electrically connected to the LED case 1 while the LED case 1 is covered with the heat dissipating member 20 so that the heat dissipating member 20 accommodated therein is not exposed to the outside, A stabilizer 110 for supplying a commercial power source externally input to the PCB 2 while varying the rated power may be mounted and an illumination bracket 120 may be mounted to be fixed to a ceiling or a wall. Here, the ballast 110 can be fixed to the outside of the lighting case 100 by bolting, and the lighting bracket 120 is fixed to the outside of the lighting case 100 by bolting, and a hole through which the bolt or the fixing pin passes is formed .

Accordingly, the LED 1 is stably emitting the illumination light as the rated power is supplied stably through the ballast 110 in a state where the illumination case 100 is stably fixed to the ceiling or the wall surface by the illumination bracket 120 can do.

The hinge member 130 may be formed on the illumination bracket 120 such that the illumination case 100 is rotated at a predetermined angle and maintained in a rotated state. The hinge member 130 includes a rotation piece 131 protruding from the illumination case 100, a fixing piece 132 protruding from the illumination bracket 120 and contacting the side of the rotation piece 131, And a rotation unit 133 for allowing rotation of the rotary member 131 or restricting rotation of the rotary member 131.

Here, the rotation part 133 may be composed of a bolt passing through the fixing piece 132 and the rotating piece 131, and a nut screwed to the bolt. Therefore, the lighting case 100 is rotated at a predetermined angle with respect to the lighting bracket 120 fixed to the ceiling or the wall surface without tightening the bolt and the nut, and then the bolt and nut are tightened to rotate the lighting case 100 The state can be stably maintained.

The illumination frame 200 is formed with at least one glove hole 210 through which the globe 30 is exposed. Thus, one or more globes 30 may protrude downward through the glove holes 210 of the illumination frame 200.

Further, the illumination frame 200 may have an outer wall 220 protruding downward from an outer or outer frame. The outer wall 220 can guide the falling downward while preventing condensation formed by external rainwater or temperature difference from penetrating through the glove hole 210.

As described above, the present invention can be applied to an illumination lamp or a street lamp so that the heat generated from the PCB 2 on which the LED 1 is mounted can be quickly radiated through the heat radiation member 20 provided in the base frame 10, And can be widely applied to a street lamp installed on a street or an outdoor street lamp installed in an office or the like.
