Abstract

A light source module includes a light source, a reflector reflecting light emitted by the light source, and a display on which the light reflected by the reflector is incident, spreading the light in a location on which the light is incident. A position of the location of the display on which light is incident continuously moves in at least one direction according to a motion of the reflector.

First claim

What is claimed is:

1 . A light source module, comprising:
a light source; a reflector reflecting light emitted by the light source; and a display on which the light reflected by the reflector is incident, spreading the light in a location on which the light is incident, wherein a position of the location of the display on which light is incident, continuously moves in at least one direction according to a motion of the reflector.

2 . The light source module of claim 1 , wherein the spread light has a pattern of moving in a direction along the display.

3 . The light source module of claim 2 , wherein the reflector implements a predetermined signal by allowing the display to repeatedly display the pattern in predetermined cycles.

4 . The light source module of claim 2 , wherein a speed and a direction of the light, of the light source, moving along the display are controlled by a rotational speed and a rotational direction of the reflector.

5 . The light source module of claim 1 , wherein the display has a structure convexly protruding in an advancing direction of the light.

6 . The light source module of claim 1 , wherein the display is semitransparent or non-transparent and includes a light-spreading material.

7 . The light source module claim 1 , wherein the reflector has a rotational axis in a direction perpendicular to an optical axis of the light source and rotates in a clockwise or counter-clockwise direction with respect to the light source.

8 . The light source module claim 1 , wherein the reflector includes a first plane and a second plane disposed opposite to the first plane and reflects the light emitted by the light source through the first plane and the second plane.

9 . The light source module of claim 1 , wherein the light source includes a semiconductor light-emitting device emitting light having linearity.

10 . The light source module of claim 1 , wherein the light source includes a package body having a recess, an LED chip mounted in the recess, a wavelength conversion layer filling the recess and encapsulating the LED chip, and a lens disposed on the LED chip.

11 . The light source module of claim 1 , further comprising a driver driving the reflector to rotate.

12 . The light source module of claim 1 , wherein the light source is the only light source emitting the light that is reflected by the reflector.

13 . A light source module, comprising:
a light source emitting light having linearity; a display on which the light emitted by the light source is incident, spreading the light in a location on which the light is incident; and a reflector disposed on a path of light to have a rotational structure and reflecting the light emitted by the light source to the display, wherein a motion of the reflector is controlled to implement a pattern of an image in which the light incident on the display moves in at least one direction along the display.

14 . The light source module of claim 13 , wherein a moving pattern of the light moving along the display is repeatedly displayed in predetermined cycles, and the cycle, a moving speed, and a moving direction are controlled by a rotational speed and a rotational direction of the reflector.

15 . The light source module of claim 13 , wherein the light source is the only light source emitting the light that is reflected by the reflector.

16 . A lighting device, comprising:
a light source module; a housing accommodating the light source module therein; and a cover installed on the housing and covering the light source module, wherein the light source module is the light source module of claim 1 .

17 . The lighting device of claim 16 , wherein the cover partially includes a display of the light source module.

18 . A light source module, comprising:
a display including a plurality of regions arranged in one direction; and a rotatable reflector receiving light emitted by a single light source, and reflecting the received light to the display, wherein the plurality of regions of the display are sequentially illuminated along the one direction by the reflected light in accordance with rotation of the rotatable reflector.

19 . The light source module of claim 18 , wherein each of the plurality of regions spreads the reflected light incident thereto.

20 . The light source module of claim 18 , wherein a moving pattern of the light moving along the display is repeatedly displayed in predetermined cycles, and the cycle, a moving speed, and a moving direction are controlled by a rotational speed and a rotational direction of the reflector.
