Lighting device and lighting fixture

Abstract

A lighting device (10) 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.

Description

technical field [0001] The present invention relates to a lighting device and a lighting fixture using a semiconductor light emitting element such as a light emitting diode as a light source. Background technique [0002] In recent years, instead of incandescent lamps (electric filament lamps), lighting devices such as bulb-type light-emitting diode (light-emitting diode, LED) lamps, which use semiconductor light-emitting elements with long life and low power consumption, that is, light-emitting diodes, as light sources, have been adopted as lighting devices. Light source for various lighting fixtures. When constituting an illuminating device using such a light emitting diode as a light source, it is necessary to take advantage of the advantages of the light emitting diode to be compact, to increase productivity for mass production, and to obtain a light beam equivalent to an incandescent lamp. [0003] For example, JP-A 2008-91140 (publication) discloses an LED light bulb ...

AI Technical Summary

Problems solved by technology

Therefore, there are problems that the connection part of the power supply wire is disconnected due to external force when the board is fixed to the appliance body, or the wire is detached from the quick-connect terminal of the terminal board, making it unsuitable for mass production.
