[0107] Next, a lighting device 1 according to a second embodiment of the present invention will be described with reference to FIG. 5 . Incidentally, the same components as those in the first embodiment are denoted by the same reference numerals, and descriptions thereof are omitted.

[0108] In this embodiment, the difference from the lighting device 1 according to the first embodiment is that it is only arranged so as to be aligned with the design optical axis L2 of the light guide portion 9 of the light guide member 2 (see Figure 1B ) consistent with one first LED 14A is provided on one light source unit 3A, and is arranged only with the design optical axis L2 of the light guide portion 9 of the light guide member 2 (see Figure 1B ) consistent with another first LED 14B is provided on another light source unit 3B.

[0109] In addition, the optical characteristics of the light guide member 2 easily form a light gradient so that light emitted from one first LED 14A brighte...

Abstract

An object of the present invention is to provide a vehicle interior lighting device capable of showing light movement with a small number of light sources and capable of reducing costs. The vehicle interior lighting device (1) includes: a light guide member (2); a light source unit (3A); another light source unit (3B); and a control unit (31). The control unit (31) turns on another light source unit (3B) after turning on one light source unit (3A), turns off one light source unit (3A) after turning on another light source unit (3B), and turns off one light source unit (3A) Then switch off the other light source unit (3B).

Description

technical field [0001] The present invention relates to an on-vehicle interior lighting device for illuminating a cabin of a vehicle or the like. Background technique [0002] Such as Figure 6 As shown, as the vehicle-mounted interior lighting device 101, it is proposed that by arranging a plurality of light sources 121 to 128 in the cover 120, by sequentially lighting the light sources 121 to 128 in one direction, and by sequentially turning off the light sources in one direction, 121 to 128 to produce lighting effects that make light flow in one direction, such as Figure 7 shown (for example, see Patent Document 1 to Patent Document 3). [0003] In such an on-vehicle interior lighting device 101 , lighting and turning off of the light sources 121 to 128 are controlled by a control unit 131 having a control circuit.
