Lighting device and lighting fixture

摘要

A lighting device (10) and a lighting fixture (30) of the embodiment of the present invention comprises a thermally conductive main body (13) having a substrate support portion (13e) in one end portion, and having a through-hole (13g) and a groove portion (13h) formed in the substrate support portion (13e), the through-hole (13g) penetrating from the one end portion to the other end portion of the main body (13), the groove portion (13h) extending continuously from the through-hole (13g), a substrate (14) mounted with a semiconductor light-emitting device (11), and disposed on the substrate support portion (13e), an electrical connector (15) connected to the semiconductor light-emitting device (11), a power supply device (12) housed in the main body (13) and configured to light the semiconductor light-emitting device (11), a wire (16) connected to the power supply device (12) and to the electrical connector (15) while being inserted through the through-hole (13g) and the groove portion (13h), and a base member (17) provided in the other end portion of the main body (13)and connected to the power supply device (12). Therefore a lighting device (10) and a lighting fixture (30) of this embodiment of the present invention reduced in size, is configured to be suitable for mass production and is capable of producing a certain luminous flux.
