  • Patent number: 10465876
    Abstract: Methods and apparatuses provide a supplemental light source, such as a strobe light, for a motor vehicle. An adapter may be provided to mount a supplemental light source to an existing primary light source, such as a parking and turn signal light bulb. A wiring assembly may interconnect the supplemental light source with a controller, such as a switch. The combined primary and supplemental light sources may then be inserted into a vehicle light housing through an existing light bulb aperture, without creating additional apertures or otherwise modifying the light housing.

  • Patent number: 10393348
    Abstract: An array of LEDs is supported by a support mechanism that both supports conductors leading to the LEDs and sinks heat from the LEDs. The support mechanism may be a transparent heat-conducting sheet or an array of cantilevered arms at different angles that support the LEDs and sink heat. This reduces the blockage of light. The LEDs are positioned generally in the focal plane of an array of concave mirrors that collimate the light. The LEDs and array of mirrors are translatable with respect to one another to steer the aggregate light beam to customize the emission. In another embodiment, multiple LEDs are positioned over each mirror in the mirror array, and the combination of LEDs illuminated over each mirror is used to steer the aggregate light beam from the luminaire.

  • Patent number: 10364975
    Abstract: A light module includes a light emitting diode (LED) array and a double-reflective assembly coupled to the LED array. The double-reflective assembly includes a lower member having a frame. The frame has an opening corresponding to the LED array. The frame and LED array are located in the same plane. The light module further includes a left bottom reflector and a right bottom reflector. The light module further includes an upper member which includes a left top reflector; and a right top reflector, wherein the left top reflector is attached to the left bottom reflector, and right top reflector is attached to the right bottom reflector, each forming an arbitrary left and right double-reflective assembly. A shape geometry and profile of each double-reflective assembly provides a pre-calculated combined non-circular asymmetrical intensity distribution pattern.

  • Patent number: 10285232
    Abstract: A headlight for a motor vehicle includes at least two light sources and a driver, which is arranged to vary the light intensities of the light sources with a phase shift to one another periodically between a minimum and a maximum and in the course of a period to set intermediate values between the maximum and the minimum. In a phase of the period, in which the first light source reaches the maximum of its light intensity, the light intensity of the second light source is situated at an intermediate value and increases.
