Fluorescent lamps and recently LEDs are mainly used as lighting means for evacuation guidance lights. Fluorescent lamps and LEDs lose strength as the distance increases and are scattered by smoke or dust. The visible distance that can be done is rapidly shortened, and it is not possible to perform its functions properly.

Recently, an evacuation guidance lamp has been proposed that irradiates a laser beam that can be easily recognized even if smoke fills up inside a building due to a fire, as the light intensity does not decrease and it goes straight for a long distance and does not lose its straightness even when passing through smoke. is becoming Registered Patent No. 0699361 discloses a non-path induction using a laser diode and an optical lens to project characters and symbols. The laser beam as in the above registered patent has strong straightness and excellent transmittance even in thick smoke, so it can be recognized quickly from a long distance.

On the other hand, shadow (gobo) lighting has been used a lot in recent years for advertisements of products installed in department stores or roads, and for policy promotion of city or ward offices. A shadow illuminator is a lighting that projects the LED light onto the image glass to illuminate the wall, floor, and ceiling of a building to use the principle that light transmits through the concave and convex lenses.

Such a shadow illuminator is a device that displays light on a surface such as a screen, and a user connects a power source to an illuminator that generates light and passes light through an image filter to transmit the desired content.

Korean Patent Laid-Open No. 10-2021-0061612 discloses a portable gobo illuminator that produces a gobo lighting effect using an LED light source, a plurality of lenses, and an image filter. Conventionally known shadow lighting devices, such as the portable gobo illuminator, can be effective for advertisements and for providing information to inform events, but when a fire occurs, light is reflected due to smoke or the illumination is weak, so to guide an emergency door or an evacuation route located at a remote location. was difficult
