  • Patent number: 10220770
    Abstract: A guide lamp for a vehicle is provided that guides nearby vehicles or pedestrians as to the path of a vehicle. The guide lamp includes a sensing unit that is configured to sense a path change attempt of the vehicle and a lamp unit that is configured to generate a road beam pattern indicating a direction toward the path change of the vehicle. The lamp unit includes one or more light sources and a light emitter that is configured to generate the road beam pattern by emitting light generated by the light sources in two or more different directions.

  • Patent number: 10076995
    Abstract: An automotive lamp provides information to vehicles approaching from at least one side of the rear of a vehicle of the driving state of the vehicle by irradiating light for forming a road pattern indicating the driving state of the vehicle. The automotive lamp includes a detection unit configured to detect a driving state of a vehicle, a reversing lamp configured to indicate a reverse movement of the vehicle, a lamp unit configured to irradiate light for forming a road pattern indicating the state of the vehicle to the rear of the vehicle such that the road pattern can be formed on at least one side of the vehicle. A control unit is configured to control the lamp unit based on the detected driving state of the vehicle. The luminous intensity of the lamp unit is equal to, or greater than, the luminous intensity of the reversing lamp.

  • Patent number: 10006600
    Abstract: Provided is an automotive lamp which forms a stereoscopic image by transmitting light of a light source through a lenticular lens. The automotive lamp includes: a light source; and a light pattern forming component which forms a plurality of light patterns by transmitting light emitted from the light source, wherein the light pattern forming component enables a light pattern of a different image to be observed based on a viewing angle, and light patterns of different images provide a continuous motion as the viewing angle changes sequentially in a specific direction.

  • Patent number: 9889792
    Abstract: The present disclosure provides an automotive lamp, and more particularly, to an automotive lamp capable of informing an ambient vehicle approaching from one side behind the vehicle of a vehicle state by irradiating light of a road pattern to indicate the vehicle state to an area behind the vehicle. The automotive lamp includes a lamp unit disposed in a rear lamp housing of a vehicle and a detection unit configured to detect whether a reverse shift stage is selected. The lamp unit is configured to irradiate a first light distribution pattern that forms a reversing light signal pattern in the rearward direction of the vehicle, and a second light distribution pattern that forms a road pattern on the rearward road surface of the vehicle. The first light distribution pattern and the second light distribution pattern are formed simultaneously, when the reverse shift stage is selected.
