  • Patent number: 11092308
    Abstract: A light emitting element, a reflector, a projection lens, and a movable shade are arranged in a lamp chamber. As the movable shade is erected, a low beam is formed. As the movable shade is tilted, a travelling beam is formed. The reflector and a sub reflector are integrally formed. The movable reflector reflects the reflected light reflected by the sub reflector toward the projection lens. The sub reflector is positioned in a range of an outer shape of the projection lens.

  • Publication number: 20210025560
    Abstract: A first camera unit (111) acquires an image including at least an area ahead of a vehicle based on a first optical axis (X1). A second camera unit (112) acquires an image including at least an area on the left of the vehicle based on a second optical axis (X2). When viewed from an up-down direction of the vehicle, the first optical axis (X1) and the second optical axis (X2) intersect with each other.

  • Patent number: 10711966
    Abstract: A light source includes a substrate on which an excitation light source is mounted, a lens including a light transmitting portion that transmits light from the excitation light source and a body attached to the substrate, a first thermal expansion absorber that protrudes from the body and has high heat resistance and elasticity, and a cover fixed to the substrate in a state where the body of the lens is sandwiched between the cover and the substrate via the first thermal expansion absorber.

  • Patent number: 9981595
    Abstract: Provided is a vehicle lamp including an optical unit including an optical element and a solenoid that drives the optical element; and a driving circuit configured to receive a voltage from a DC power supply and apply a driving voltage to the solenoid. The driving circuit includes a signal generating circuit that generates a notification signal indicating whether or not the solenoid is open-circuited. The signal generating circuit generates a first signal as the notification signal when the solenoid is normal. The notification signal is set as a second signal that is different from the first signal when open-circuit of the solenoid is detected.

  • Patent number: 9546768
    Abstract: A vehicle headlamp includes a lamp unit including a light source and being disposed inside a lamp outer casing, an actuator including a drive shaft and being detachable from a certain portion, a joint including a coupling portion and being detachable from the lamp unit, the coupling portion being coupled to the drive shaft in a state in which the joint is attached to the lamp unit. The lamp unit includes a plurality of unit configuration portions including the light source. The lamp unit is formed with a communication space which opens at least downward. At least one of the unit configuration portions can be removed at least downward through the communication space in a state in which the actuator has been detached from the certain portion and the joint has been detached from the lamp unit.
