  • Lamp unit and vehicle headlamp
    Patent number: 10359169
    Abstract: A lamp unit includes a light-emitting element array composed by a plurality of light-emitting elements, having respective individual irradiation regions constituting a high-beam light-distribution pattern and configured to be capable of being turned on individually, mounted in array on a substrate, a projection lens disposed in front of the light-emitting element array, and a reflector disposed below the light-emitting element array. Inter-light-emitting-element spacing within the light-emitting element array widens the more separated the elements are from the projection lens' optical axis.
    Type: Grant
    Filed: January 23, 2017
    Date of Patent: July 23, 2019
    Assignee: KOITO MANUFACTURING CO., LTD.

  • Vehicular infrared irradiation lamp
    Patent number: 8292479
    Abstract: A vehicular infrared irradiation lamp includes an infrared light-emitting element for projecting infrared light; a visible light-emitting element that emits visible light; and a transparent member provided at least partially adjacent to a light-emitting portion of the infrared light-emitting element. The transparent member radiates visible light received from the visible light-emitting element in a radiation direction of infrared light.
