Embodiment Construction

[0071] An illumination device in an embodiment includes: a light emitting part having a light emitting element; a light guide part provided on a light irradiation side of the light emitting part; and a reflection part having a An end portion on the opposite side, a through hole exposing the light guide part, and a first reflective surface inclined in a direction toward the central axis of the light guide part toward the light emitting part side.

[0072] According to this illuminating device, the intensity of light irradiated in a predetermined direction can be increased.

[0073] Also, the light guiding part may further have an illuminating part protruding from the through hole.

[0074] As long as there is an irradiating portion protruding from the through hole, the light distribution of light irradiated toward the front side of the lighting device can be easily controlled by changing the shape, size, etc. of the irradiating portion.

[0075] Furthermore, the reflective por...

Abstract

A lighting device (1) according to an embodiment includes: a light emitting section (2) that has a light emitting element (21); a light guide (4) that is provided on a side of radiation of light of the light emitting section (2); and a reflection section (5) that is provided in an end section of the light guide (4) on the side opposite the side of the light emitting section (2) and includes a through hole (5b) that exposes the light guide (4) and a first reflection surface (5a) that is inclined in a direction in which a side of the light emitting section (2) approaches a side of a center shaft of the light guide (4).

Description

technical field [0001] Embodiments of the present invention relate to a lighting device and a lighting device for a moving object. Background technique [0002] A conventional lighting device includes a light emitting element such as a light emitting diode (LED), a light guide for guiding light irradiated from the light emitting element, and a dispersion section provided at the tip of the light guide. [0003] According to such a lighting device, for example, the same light distribution characteristic as that of an incandescent bulb can be obtained. [0004] However, depending on the use of the lighting device, etc., it may be preferable to increase the intensity of light irradiated in a predetermined direction. [0005] Furthermore, when light is irradiated through the dispersing part, the loss may increase.
