EMERGENCY LED ILLUMINATION DEVICE FOR FIRE PREVENTION

摘要

PURPOSE: An emergency LED device for preventing a fire is provided to enable people to evacuate a dangerous zone by providing light of a long wavelength in an emergency situation. CONSTITUTION: A lighting unit(110) is received in a housing. Long wavelength LEDs are alternatively arranged on a substrate in the lighting unit. A switching module(180) forms a current path from the lighting unit. An SMPS(Switching Mode Power supply) temperature sensor is formed in an SMPS(140). A sensor module(120) includes a smoke sensor and a temperature sensor.
