US 2021/0170940 A1 · LAMP FOR VEHICLE

Abstract

A lamp for a vehicle includes a lamp unit including a plurality of light emitting areas arranged in a direction; a mode determination unit configured to determine a selected light emitting mode among a plurality of light emitting modes of the lamp unit; and a control unit configured to cause at least one of the plurality of light emitting areas to generate light having a first color or a second color based on the determined light emitting mode. In particular, the plurality of light emitting modes comprises: a first light emitting mode in which the light of the first color is generated from the plurality of light emitting areas; and a second light emitting mode in which the light generated from each of the plurality of light emitting areas is changed from the first color to the second color sequentially.

A lamp for a vehicle, comprising:

a lamp unit including a plurality of light emitting areas arranged in a direction;
a mode determination unit configured to determine a selected light emitting mode among a plurality of light emitting modes of the lamp unit;
and
a control unit configured to cause at least one of the plurality of light emitting areas to generate light having a first color or a second color based on the determined light emitting mode,
wherein the plurality of light emitting modes comprises:
a first light emitting mode in which the light of the first color is generated from the plurality of light emitting areas;
and
a second light emitting mode in which the light generated from each of the plurality of light emitting areas is changed from the first color to the second color sequentially from a first side to a second side along the arrangement direction of the plurality of light emitting areas.

A method of operating a lamp for vehicle comprising a plurality of light emitting areas each configured to generate light having a first color or a second color, the method comprising:

generating the light of the first color in each of the plurality of light emitting areas;
during a first time segment of a turn-on period, changing the light in each of the plurality of light emitting areas from the first color to the second color sequentially from a first side to a second side along an arrangement direction of the plurality of light emitting areas;
during a second time segment of the turn-on period, which follows the first time segment of the turn-on period, generating the light of the second color in each of the plurality of light emitting areas;
and
changing the light in each of the plurality of light emitting areas from the second color to the first color simultaneously and sustaining the light of the first color during a turn-off period,
wherein the first time segment of the turn-on period is initiated in response to a turn signal being input, and thereafter, the first time segment of the turn-on period, the second time segment of the turn-on period, and the turn-off period are repeated.
