Abstract

There is provided a lighting apparatus using a filter and a condenser for LED illumination in which an optical filter to obtain diverse optical patterns as a user desires is connected to a condenser for LED illumination without using any additional device.

The lighting apparatus in which the optical filter can be exchanged comprises: a LED for generating a light source for illumination, a condenser for concentrating the light source generated from the LED, and an optical filter connected to the condenser, for providing an optical pattern, wherein the optical filter is connected to the condenser so as to be attachable to or detachable from the condenser.

Claims

1. A lighting apparatus using a filter and a condenser for LED illumination, comprising:

a LED for generating a light source required for illumination;

a condenser for concentrating the light source generated from the LED; and

an optical filter connected to the condenser, for providing an optical pattern, and

wherein the optical filter is connected to the condenser so as to be attachable to or detachable from the condenser.

2. The lighting apparatus according to claim 1, wherein a connecting unit for connecting the optical filter to the condenser is a hook device formed to be connected to each of the optical filter and the condenser.

3. The lighting apparatus according to claim 2, wherein the hook device comprises:

a connection opening formed at both ends of the condenser, and a connection hook formed at both lower ends of the optical filter, to be connected to the connection opening formed at the condenser.

4. The lighting apparatus according to claim 1, wherein the optical filter changes a direction and a pattern of light being reflected in the condenser.
