1. A lighting device comprising:
- a body;
a light emitting module which is disposed on the body;
an optical member which is disposed on the light emitting module and is installed to be movable along an optical axis of the lighting device; and
a reflector which is disposed between the body and the optical member and reflects light emitted from the light emitting module,wherein a shape of the reflector is changed according to the moving of the optical member and direct pressure of the optical member on the reflector,wherein a light distribution angle and a light distribution range of light passing through the optical member are variable depending on the change of the shape of the reflector,wherein the reflector includes a plurality of reflection plates, and wherein the light emitting module includes a hinge in order that each of the reflection plates is movably coupled to the body, andwherein the reflection plates are automatically folded by gravity, and wherein the optical member controls unfolding of the reflection plates.

Abstract
A lighting device includes a body, a light emitting module disposed on the body, an optical member disposed on the light emitting module and configured to be movable up and down, and a reflector disposed between the body and the optical member; a shape of the reflector being changed by moving the optical member, such that the light distribution angle and range of light reflected by the reflector and passing through the optical member are adjusted.

9. A lighting device comprising:
-
a body which has one side; a light emitting module which is disposed on the one side of the body; a cap which is disposed on the light emitting module and through which light emitted from the light emitting module passes; a reflector which is disposed between the one side of the body and the cap and surrounds the light emitting module; and a cover which includes an opening in which the cap is disposed and is coupled to the body in such a manner as to be movable up and down on the one side of the body, wherein an inclination of the reflector based on the one side of the body is changed by the moving cover and direct pressure of the cap on the reflector, wherein the reflector includes a plurality of reflection plates, and wherein the body includes a hinge in order that each of the reflection plates is movably coupled to a surface of the body, and wherein the reflection plates are automatically folded by gravity, and wherein the cap controls unfolding of the reflection plates. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
