OPTICAL SYSTEM LIGHTING FOR BEAM SHAPING AND SENSOR LAMP USING IT WHEN FIRE OCCURRED

摘要

PURPOSE: An optical system lighting and a sensor light using the same in a fire are provided to irradiate the light with high output and reduce damage to an optical lens. CONSTITUTION: A collimating lens(13) is positioned between a plurality of Fresnel Lenses(17,18) and a light source(11). The Fresnel Lenses and the collimating lens optical system are mounted inside the sensor light case. A controller controls a fire sensing signal from the sensor sensing the temperature and smoke. A main light source of the sensor light is not turned on and a circuit is switched and connected to a DC emergency power unit. The light emitted from the light source is shaped to the required shape displaying the indication direction.
