Development of 'Simple-Selcon N Type' luminary with built-in PIR sensor

摘要

A compact PIR sensor control unit was developed using semiconductor switching for high reliability and using a power-efficient switching power supply. The sensor was incorporated into a lighting fixture with the same form factor as a conventionaltwo-tube FHF32 luminaries. These "Simple Selcon N Type" lighting fixtures offer energy-saving sensor-controlled lighting without special electrical construction.
