Abstract: Embodiments of the present invention relate to a lighting apparatus capable of providing three-dimensional effects at the same time as the surface emission of light sources by using a half-mirror member for reflecting and transmitting parts of light. In particular, by adopting the half-mirror member for transmitting a part of and reflecting another part of light emitted from a surface-emitting light source module, the present invention allows the implementation of a mirror-like image when the light is off, and allows the implementation of a light image providing various three-dimensional effects when the light is on.

Abstract: Embodiments of the present invention relate to a lighting apparatus which allows a three dimensional effect to be felt while surface light is emitted in a light source using a half-mirror member configured to reflect and transmit some light. Particularly, the present invention employs a half-mirror member configured to transmit some light emitted from a light source module configured to emit surface light and reflect the remaining light to implement an image like that reflected by a mirror when the lighting apparatus is off and a light image through which various three-dimensional images are felt when the lighting apparatus is on.
