  • Patent number: 10676015
    Abstract: To eliminate a space for adjusting an optical axis, which is provided between an extension and a lamp unit to adjust the optical axis of a headlight. An extension and a lamp unit are contained in a housing. The circumference of the lamp unit is joined to the extension, whereby the lamp unit is fixed to the extension so as to eliminate a space between the circumference of the lamp unit and the extension. The extension is coupled to the housing via an optical axis adjuster. The optical axis adjuster makes the extension and the lamp unit tilt integrally, thereby adjusting the optical axis. Thus, the optical axis is adjustable although a conventional space for adjusting the optical axis is not provided, whereby the appearance of the headlight is improved.

    Abstract: A multifunction lighthead for mounting to a vehicle includes several groups of LEDs arranged to provide distinct light emission patterns. Each group of LEDs and associated optics are selected and positioned to produce light emission patterns needed to meet lighting standards applicable to the vehicle. Such standards may require wide angle light emission, which is enhanced by supporting groups of LEDs that project away from the vehicle body, enhancing visibility of the lighthead from directions close to a plane defined by the body panel. The projecting support for the LEDs and optics for a wide angle light emission pattern may be employed to support LEDs arranged for ground illumination. Other groups of LEDs in the same lighthead may be arranged with optics to provide area illumination in support of arrest, search, triage or other emergency functions.
