Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention; The following embodiments are provided to those skilled in the art to fully understand the present invention, and may be modified in various forms.

1 is a lighting apparatus according to a first embodiment of the present invention. FIG. 2 is a cross-sectional view taken along the line II ′ of FIG. 1.

1 and 2, the lighting device 100 includes a housing 110 formed of a lower surface 111 and a side wall 112, a reflector plate 120, and a housing 110 that seal an upper surface of the housing 110. A heat dissipation fin 140 formed on at least one side of the support 130, the reflector plate 120, and the support 130 that extends from at least one side wall and is bent into a region corresponding to the open surface 113 of the housing 110. And a light emitting device 150 disposed on the support 130 so as to face the reflecting plate 120.

The housing 110 is a body of the lighting device 100, and includes a lower surface 111 and a plurality of sidewalls 112 extending from an edge of the lower surface 111. Accordingly, the upper surface of the housing 110 has an open surface 113 exposed to the outside. In addition, the housing 110 may have an accommodation space formed therein to accommodate the power supply unit 160. For example, the housing 110 consists of four side walls 112 extending from the edge of the lower surface 111.

In addition, the housing 110 may be formed in the longitudinal direction. In the present embodiment, the first sidewall 112a and the third sidewall 112c represent the longitudinal direction of the housing 110. The second side wall 112b and the fourth side wall 112d represent the width direction of the housing 110.

The reflective plate 120 reflects the light emitted from the light emitting element 150 and seals the open surface 113 of the housing 110. In addition, the reflective plate 120 may be formed to be bent in the inner direction of the housing 110 to improve the reflectance of the light emitted from the light emitting device 150. For example, the cross section of the reflector plate 120 may be formed in a curved shape concave toward the inside of the housing 110. In this case, the reflector 120 is disposed at a predetermined interval on the front surface of the light emitting device 150. As such, the reflective plate 120 may be formed in a concave shape on the entire surface of the light emitting device 150 to reflect the light emitted from the light emitting device 150 to the outside, thereby indirectly illuminating the light. In addition, when the reflecting plate 120 is formed in a curved shape, the light of the light emitting device 150 having the straightness may be uniformly reflected as a whole, thereby improving the light emitting area. The reflective plate 120 may be formed of a group formed of a metal such as silver, gold, copper, and aluminum to reflect light emitted from the light emitting device 150. In addition, the reflective plate 120 may extend from the side wall of the housing 110 to be integrally formed with the housing 110 or may be fabricated in a structure separated from each other and then assembled.

The support 130 is for supporting the light emitting device 150, and may be formed to extend from one sidewall of the housing 110. For example, the support 130 extends from the first sidewall 112a of the housing 110 and extends from the extension 131 to correspond to the open surface 113 of the housing 110. It may be made of a bent portion 132 bent into one area. In this case, the extension part 131 extends in the same direction as the first side wall 112a, and the bent part 132 is parallel to the direction orthogonal to the extension part 131, that is, the lower surface 111 of the housing 110. It may be formed extending in one direction.

In addition, the support 130 may further include a side wall portion 133 surrounding the side wall of the light emitting device 150. In detail, the sidewall portion 133 may be formed to extend from one end of the bent portion 132 and may be inclined to surround the sidewall of the light emitting device 150. That is, the sidewall part 133 prevents the light emitted from the light emitting device 150 from emitting to the side surface of the light emitting device 150.

Here, the support 130 may be assembled after being formed integrally with the housing 110 or manufactured in a structure separated from each other.

As such, the support 130 includes an extension part 131, a bent part 132, and a sidewall part 133 to support the light emitting device 150 and directly expose the light emitted from the light emitting device 150 to the outside. As a result, the glare and afterimage of the user can be prevented.

The heat dissipation fin 140 is for dissipating heat generated from the light emitting device 150 to the outside, and is formed to protrude in an outward direction of the reflector plate 120 and the support 130. Specifically, the heat dissipation fins 140 are formed in a cylindrical or bar shape in order to increase the heating effect, and a plurality of heat dissipation fins 140 are disposed at predetermined intervals. For example, a plurality of heat dissipation fins 140 may be disposed outside the first and third side walls 112a and 112c and the extension part 131 of the housing 110. At this time, the heat dissipation fin 140 is disposed in a direction orthogonal to the first side wall 112a. In addition, the heat dissipation fins 140 may be formed integrally with the housing 110 or the support 130.

The light emitting device 150 is disposed on one surface of the support 130 facing the reflecting plate 120. For example, the light emitting device 150 is disposed at the bent portion 132 of the support 130 facing the reflecting plate 120. In addition, the light emitting device 150 may be electrically connected to a power supply unit accommodated in the housing 110 by wiring. In addition, the light emitting device 150 may be formed of any one of an LED (Light emitting diode) or an OLED (Organic Light Emitting Diodes). Such LEDs and LEDs may be formed of a single color or a combination of different colors.

The power supply unit 160 may be accommodated in the housing 110 to turn on the light emitting device 150. In detail, the power supply unit 160 may turn on the light emitting device 150 by converting the input power supplied from the power connection pin 170 into a DC power of a DC component. In addition, the power supply unit 160 may produce various lights through dimming value control. In this case, a separate wire may be further provided between the power supply 160 and the light emitting device 150 to electrically connect the power supply 160 and the light emitting device 150.

The power connection pins 170 may be installed at both ends in the longitudinal direction of the housing 110 and may receive input power of an AC AC component supplied from the outside. In addition, the power connection pin 170 may be formed of a conductive material to receive the input power of the AC AC component supplied from the outside.

3 is a cross-sectional view for describing a method of operating a lighting apparatus according to a first embodiment of the present invention.

Referring to FIG. 3, when the input power of the AC AC component is supplied from the outside through the power connection pin 170, the power supply unit 160 changes the input power of the AC AC component into the DC power of the DC component to emit light. 150). When the light 180 emitted from the light emitting device 150 is irradiated onto the reflecting plate 120, the light 180 emitted from the light emitting device 150 is exposed to the outside by refraction and reflection of the light 180. That is, the light 180 emitted from the light emitting element 150 is refracted by the reflector 120 and exposed to the outside of the lighting apparatus 100.

As such, when the light 180 emitted from the light emitting device 150 is exposed to the outside through the reflector 120, the glare phenomenon may be prevented as the light is directly exposed. In addition, as the light is diffused through the reflector 120, the light diffusion region may be expanded.
