Lighting apparatus

摘要

It is expected to provide a lighting apparatus that can improve the radiation performance. In a lighting apparatus that includes a light source unit and a heat sink radiating the heat generated by the light source unit and is recessed and installed to an attaching hole opened on a mounted portion, the heat sink is exposed at least partially to a side where the light from the light source unit is emitted from the attaching hole. For example, when installed to a ceiling having a heat insulated structure, the heat generated by the light source unit and transferred to the heat sink is transferred inside the heat sink and radiated from one part to the air at the side where the light from the light source unit is emitted from the attaching hole. Therefore, the radiation performance can be improved.

主权项

1. A recessed lighting apparatus that emits light in a predetermined direction, comprising:
a light source that generates the light; a radiator that radiates heat generated by the light source; a terminal block that is connected to plural electric wires for supplying power or signal; and plural mounting members,wherein
a part of the radiator is exposed in a direction opposite to the predetermined direction, a direction for connecting the plural electric wires to the terminal block is substantially equal to a direction from the terminal block to at least one of the plural mounting members, the terminal block is configured with a first terminal block portion and a second terminal block portion, the first terminal portion is connected to an electric wire having a higher rigidity than an electric wire connected to the second terminal portion, and a direction from the first terminal block portion to the second terminal block portion is substantially equal to the predetermined direction.
