DIRECTLY EMBEDDED LED LUMINAIRE WITH SEPARATE POWER SUPPLY DEVICE, AND DIRECTLY EMBEDDED THIN LED LUMINAIRE WITH SEPARATE POWER SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a directly embedded LED luminaire with a separate power supply device, and a directly embedded thin LED luminaire with a separate power supply device, enabling miniaturization of a lamp heat sink, reduction of thermal influence on a semiconductor, and replacement of a lamp only at the end of the lifetime of an LED by separately placing a LED light source and a power supply device while maintaining compatibility with a current lighting fixture.;SOLUTION: This luminaire fits an existing circular opening portion for embedding and an existing lighting fixture, and has an LED lighting fixture provided with an LED lamp and a power supply device separately placed, and an exclusive dc wiring to connect between the terminal portion of the LED lamp and the power supply device which are separately placed. This thin luminaire fits an existing circular opening portion for embedding, and constituted of a thin lighting fixture, an LED lamp with a thin heat sink provided at the upper end corner inside the thin lighting fixture with an exclusive base inclined, and a power supply device provided separately from the exclusive base through an exclusive dc wiring.;COPYRIGHT: (C)2011,JPO&INPIT
