Here, the projection surface 20 of the lighting device 200 according to the present invention is used for the wall of the building, it is preferable to be used as an indirect light rather than direct lighting is located in the wall, ceiling, etc. in the interior of the building.

The housing 220 is formed such that all the portions except the opening 221 can not transmit light so that the light generated by the light source unit 210 can be irradiated through the opening 221. Any configuration can be used as long as the light generated by the light source unit 210 can be irradiated through the opening 221.

For example, the housing 220 has an opening 221 formed at one end thereof, and the cross section may have one of a cylinder shape, a horn shape, and a horn shape having a circle, an ellipse, various shapes, and a polygonal shape. Can be.

The housing 220 is provided with a fixing member such as a bracket (not shown) so that the light source unit 210 to be described later is installed, and a wire (not shown) for supplying power to the light source unit 210 is penetrated therein. It may be installed, such as a configuration for power supply and fixing of the light source unit 210.

The opening 221 is a portion in which the light generated by the light source unit 210 is emitted and may have various shapes such as a rectangle, a circle, an ellipse, and a star shape.

In particular, the opening 221 passes through the pattern forming unit 230 through which light generated by the light source unit 210 passes to form an outline of an image projected onto the projection surface 20.

Therefore, the contour of the image projected on the projection surface 20 may be variously formed according to the shape of the opening 221.

On the other hand, the housing 220 may be further coupled to the installation member for installation on the bar, ceiling, etc. bar installed in the building.

The light source unit 210 is installed inside the housing 220 to generate light, and may include one or more LED elements, in particular, one LED element.

The light source unit 210 may have any configuration as long as it includes a LED element to generate light.

The pattern forming unit 230 is configured to be installed on the optical path generated from the light source unit 210 so that the pattern 21 is included in the light projected on the projection surface 20 can be various configurations.

For example, the pattern forming unit 230 may be made of transparent glass, synthetic resin, or the like, and may be configured as a transparent member having patterns of various patterns formed on the surface thereof, or may be variously configured such as a transparent display device through which light is transmitted.

In this case, when the transparent display device that transmits light to the pattern forming unit 230 is used, the display signal may be remotely transmitted by wire or wirelessly.

The pattern formed by the pattern forming unit 230 may be configured in various ways, including at least one of a still image and a video.
