Lighting control device and lighting control method for vehicle lamp, and vehicle lamp system

Abstract

The purpose of the present invention is to reduce the feeling of discomfort when performing a sequential turn instruction. A lighting control device for a vehicle lamp is used for controlling lighting of the vehicle lamp, and the lighting control device carries out the following control: flickering a light emitting area of the vehicle lamp at a first brightness; during the lighting of the light-emitting region, either one or more bright spots formed by causing a partial region of the light-emitting region to have a second luminance higher than the first luminance, or one or more dark spots formed by causing a partial region of the light-emitting region to have a second luminance higher than the first luminance, are moved within the light-emitting region. The one or more dark spots are formed by causing a partial region of the first light-emitting region to have a third brightness lower than the first brightness.

Description

technical field [0001] The present invention relates to, for example, a vehicle lighting system used as a turn signal (winker). Background technique [0002] As one type of winkers used in vehicles, there is known a winker in which a plurality of light emitting units are sequentially turned on with a time difference (for example, refer to Patent Document 1). Here, such a lighting method is called sequential turn indication. A vehicle lamp that performs such a sequential turn instruction is, for example, controlled to repeat an operation in which each light emitting unit is turned on sequentially from the inside toward the outside of the vehicle, and then all the light emitting units are simultaneously turned off. [0003] However, in the vehicular lamps that perform sequential turn instructions as described above, people who visually recognize the vehicular lamps (for example, pedestrians, drivers of other vehicles, etc.) increase the recognition of lateral movement from th...

Problems solved by technology

[0003] However, in the vehicular lamps that perform sequential turn instructions as described above, people who visually recognize the vehicular lamps (for example, pedestrians, drivers of other vehicles, etc.) increase the recognition of lateral movement from the inside of the vehicle toward the outside. such a load

Therefore, compared with the conventional type of turn signal that simply blinks repeatedly, the turn signal that performs sequential turn indication may bring a sense of incongruity as a light for direction indication.
