Light emitting diode device having structure for preventing thermal deformation

The present invention relates to an LED illuminator, and more particularly, to heat the heat generated by the LED to the outside of the illuminator to prevent thermal deformation of the illuminator and reinforce the strength of the base to minimize the thermal deformation even if high temperature is generated An LED illuminator having a prevention structure.

As a conventional illuminator, illumination light sources, such as a fluorescent lamp and a halogen bulb, are used. The light source generally has a problem of high heat generation, weak vibration, and large amount of electric power. In addition, the irradiator using the light source as an irradiation light source requires a replacement operation as the lamp goes out, and the illumination structure becomes large, and the voltage fluctuations. There is a drawback that the change in the amount of light is large, so that the practicality is not sufficient.

In order to solve the above problem, a change from a conventional light source to an illuminator using an LED (LED) light source has been sought.

Illuminator using the LED light source according to the prior art may be divided into being suspended on the ceiling or installed on the wall according to the installation position.

Hereinafter, it will be described as an example that is installed on the ceiling, the conventional illuminator is disposed on the base, the illumination plate disposed on the bottom of the base, the circumference of the illumination plate is fixed to the base by a plurality of fasteners to support the illumination plate The front frame, which is inserted into the inside of the front frame is composed of a light emitting module for irradiating light to the illumination plate.

The light emitting module includes a printed circuit board (PCB) electrically connected to a power supply unit and a plurality of LEDs that are lit by a power applied to the printed circuit board.

The front frame is composed of four frames woven in the form of a square frame. The frame has a module insertion part which is opened toward the lighting plate side to insert the light emitting module therein, and has a box-shaped frame body having diagonal portions at both ends in the longitudinal direction, and extending toward the center from the front side of the frame body. The plate is supported by a light plate support portion, extending from the rear side of the frame body toward the outside and a jaw is formed at the end is made of the base support is fixed to the fastener as the base is seated.

The four frames configured as described above are coupled in a direction perpendicular to each other along the shape of the base and are coupled to be in contact with diagonal portions on both sides.

The power supply unit is installed in the center of the base as a box mounted with a PC, safety device, etc., in which an electric element is mounted.

According to a conventional lighting fixture using the LED as a light source has the following problems.

The LED of the light emitting module generates heat of high temperature when it is turned on by applying power, and the heat formed by the lighting plate, the base, the front frame, and the power supply unit is sealed from the outside, so the heat generated from the LED is heat. This does not diverge outside, resulting in a rise in temperature inside the fixture over time. Accordingly, there is a problem that thermal deformation (bending deformation due to heat) of the lighting plate and the base occurs.

In addition, as the power supply unit supplies power to the LEDs, high-temperature heat is generated from itself, and the heat is transferred to an enclosed space formed in the lighting plate, the base, the front frame, and the power supply unit, and the heat is generated larger than the heat generated from the LEDs. There is also a problem that causes thermal deformation.

And, when the fixture is suspended from the ceiling hanger structure for hanging the fixture is formed. The hanger structure of the conventional illuminator is a method of cutting and bending a portion of the base to form a hanger portion, and a hanger or the like fixed to the ceiling is fixed to the hanger. However, the hanger part of the conventional illuminator is formed integrally with the base so that the bent part may be broken, and if the position of the ceiling hanger does not match, the hanger may be suspended from the ceiling. There is also a problem.

The present invention is to solve the problems as described above, even if the light emitted from the LED and the heat of the power supply itself is generated by circulating the external low temperature air inside the illuminator so that the illuminator temperature does not rise to high temperature and illuminator temperature It is an object of the present invention to provide an LED illuminator capable of preventing heat deformation in which the structure is not thermally deformed by reinforcing the strength of the structure even if the value rises.

LED illuminator capable of preventing the heat deformation according to the present invention for achieving the above object, a plate-shaped base; A light emitting module having a plurality of light emitting diodes mounted on the light receiving power; An illumination plate seated on one surface of the base and emitting light emitted from the light emitting module; And a front frame coupled to a circumference of the base to support the lighting plate, wherein the base includes a heating hole and a reinforcing part for dissipating heat inside the fixture to the outside.

According to the LED illuminator capable of preventing heat deformation according to the present invention, the heat generated inside the illuminator (heat caused by the light irradiated by the LED, the heat of the power supply itself) is discharged to the outside, and the internal temperature of the illuminator causes deformation of the structure. Since it does not rise to the temperature, it is possible to prevent thermal deformation of the lighting plate, base, etc., and also, even if the internal temperature of the fixture increases to some extent, the base is strengthened through the beads and ribs, so that the support for bending deformation is exerted. It can prevent the deformation of the structure, which can improve the durability of the product and extend its life.

The hanger pin for hanging the fixture on the ceiling is detachably installed so that the hanger pin can be installed according to the position of the hanger fixed to the ceiling, and the hanger pin is arranged at the circumference of the fixture to facilitate the illuminator. It can be installed.

The lighting plate 20 may emit light to the outside through scattering and diffuse reflection after being irradiated from the light emitting module 40, and may be an advertisement board having an editorial or the like formed on a surface thereof, or a plate for illumination only.

The light emitting module 40 is mounted on the printed circuit board 41 and the printed circuit board 41 electrically connected to the power supply unit 60 through a wire or the like, and the power supply unit 60 through the pattern of the printed circuit board 41. It consists of a plurality of LEDs 42 that are powered on from the power supply.

The front frame 30 is a quadrangular frame form is composed of four frames (30-1, 30-2, 30-3, 30-4) are combined.

Since the frames 30-1, 30-2, 30-3, and 30-4 have the same configuration, only one example will be described in detail.

As shown in FIG. 2, the frame 30-1 extends toward the center of the box-shaped frame body 31 having the module inserting portion 31a on which the light emitting module 40 is mounted, and the inner bottom of the frame body 31. It is formed and is formed on the light plate support portion 32, the lighting plate 20 is seated, the base support portion 33 is formed extending to the outside of the frame body 31, the base 10 is seated.

The module inserting portion 31a of the frame body 31 is formed to be open toward the lighting plate 20 side, so that the light emitting module 40 is inserted. The light emitting module 40 is inserted into the module inserting portion 31a so that the LEDs 42 face the lighting plate 20.

At the end of the lighting plate support part 32 and the end of the base support part 33, support jaws 32a and 33a are formed to support the lighting plate 20 and the base 10 so as not to shake.

Frame 30-1 has diagonal portions 34 and 35 (see Fig. 3) formed at both ends thereof, respectively. The oblique portions 34 and 35 are portions to which four frames 30-1, 30-2, 30-3, and 30-4 are formed in a rectangular frame shape.

The base 10 is bent to protrude upward from the other side of the plate-shaped base body 12, the base body 12 is inserted into the inner side of the support jaw of the front frame 30, the front frame 30 Fastening part 13 fixed by the fastener 11, both ends are connected to the corner of the base body 12 and is formed to communicate with the outside in the cross bead 14, cross bead 14 protruding upwards Comprising a plurality of heat generating holes 15 for dissipating heat inside the base body 12 to the outside, a plurality of reinforcing portion 16 is formed in a square in the base body 12.

The base 10 is bent so that the fastening portion 13 is disposed above the base body 12 and does not shake with respect to the front frame 30 before fastening the fastener 11, so that the fastening operation of the fastener 11 is performed. This is easy.

The cross-bead 14 is projected to the rear by embossing the base body 12 and guides the hot air inside the base 10 to be discharged to a relatively low temperature through the heat generating hole 15 by the density difference. In order to guide the discharge rate of air rapidly, it is preferable that it is formed in a curved shape. That is, when the heat generating hole 15 is formed on the flat surface of the base body 12, light may be lost through the heat generating hole 15, but the cross beads 14 protrude upwardly (backward) from the base body 12. As light is diffusely reflected through the surface of the cross bead 14, the amount of light loss may be reduced.

The cross bead 14 may be formed diagonally to the discharge of the air to the base 10 to prevent the base 10 from bending deformation in all directions.

The heating hole 15 is formed to a size that can maximize the heating effect while minimizing the loss of light.

Although the heat inside the base 10 is released by the heat generating holes 15, the amount of this discharge is small, so that the temperature inside the base 10 may be high. Thus, even if the temperature inside the base 10 is increased, the base 10 may be increased. The reinforcement part 16 is formed so that it may not bend by heat.

The reinforcement part 16 may be formed in the base body 12 by embossing or padded on the surface of the base body 12, and a plurality of reinforcement parts may be formed at regular intervals along the sides of the base 10 at a center side. have.

The power supply unit 60 is installed in the center of the base 10 as a box on which a PC, a safety device, etc., in which an electric element is mounted, is mounted.

The present invention is coupled to a plurality of hanger pins (50). The hanger pin 50 is screwed between the periphery of the base body 12, which is the outermost part of the illuminator, and the support jaw 33a of the front frame 30, and a ring 51 is provided. In other words, the hanger is installed on the ceiling is fitted to the ring 51, the illuminator is installed.

The installation method of the present invention illuminator is as follows.

A plurality of hanger pins 50 are screwed to the illuminator to prepare the illuminator, and the illuminator is mounted on the hook 51 of the hanger pin 50 on a hook installed on the ceiling. Hanger pin 50 is installed on the outermost of the fixture is easy to hang the hook 51 of the hanger pin 50 to the hook of the ceiling.

When installing the fixture in this way, if the position of the ceiling hanger and the hanger pin 50 does not match, the fixture is crooked, the hanger pin 50 may be removed from the fixture and then screwed elsewhere to install the fixture in a predetermined position.

The action of the LED illuminator having a heat deformation preventing structure according to the present invention configured as described above is as follows.

The light irradiated from the LED 42 of the light emitting module 40 is scattered and diffused between the lighting plate 20 and the base 10 to be emitted to the outside through the lighting plate 20 to illuminate the surroundings or to the lighting plate ( If the ad text is formed in 20), the ad text is illuminated.

On the other hand, the LED 42 is heat is generated with the irradiation of light, LED 42 has the advantage that the heat generation is not large, because there is no heat at all, the heat between the lighting plate 20 and the base 10 In addition, the heat of the power supply unit 60 does not radiate to the outside and is transferred to the sealed space between the lighting plate 20 and the base 10. As the lighting time increases, the temperature between the base 10 and the lighting plate 20 increases, and as the air density increases as the temperature increases, the air density inside the fixture becomes higher than that of the outside air, and the inside of the fixture The hot air of the is discharged to the outside through the heating hole (15). The cross bead 14 is formed in a curved shape to induce the air inside the fixture to be released at a high speed, thereby preventing a sudden rise in the temperature inside the fixture.

On the other hand, it is possible to prevent the rise of the internal temperature of the illuminator by radiating the hot air inside the illuminator through the heat radiating hole 15 to the outside, but heat deformation may occur in the base 10 depending on the material of the base 10, but the base ( Since the cross bead 14 and the reinforcing portion 16 of 10) prevent the front, rear, left, and right bending deformation of the base 10, the base 10 is not bent.

Although the LED has been described as the light emitting means in the above detailed description, the present invention is not limited thereto, and the LED may be applied to a discharge type illuminator such as a cold cathode fluorescent lamp (CCFL) or an external electrode fluorescent lamp (EEFL).
