Document Type and Number:
Japanese Patent JP6960103
Kind Code:
B2
Abstract:
To provide a vehicular lighting device which can suppress the current flowing in a light-emitting element and suppress the sudden fluctuation of the entire light flux even when the voltage applied to the vehicular lighting device is increased, and provide a vehicular lighting fixture.SOLUTION: A vehicular lighting device related to an embodiment includes: a socket; and a light-emitting module provided on one end side of the socket. The light-emitting module includes: a substrate having a wiring pattern; a plurality of light-emitting elements which is electrically connected to the wiring pattern and connected in series; a plurality of thermistors which is electrically connected to the wiring pattern and connected in parallel; a first resistance which is electrically connected to the wiring pattern; and at least one second resistance which is electrically connected to the wiring pattern. The plurality of thermistors connected in parallel is connected in series to the plurality of light-emitting elements connected in series, the first resistance and the second resistance.SELECTED DRAWING: Figure 2
