10429555 · 2019-10-01 ·

An automobile headlamp comprising a light source; a photochromic lens; and a one-way mirror positioned between the light source and the photochromic lens such that when viewing the light source through the photochromic lens, the one-way mirror conceals at least a portion of the light source.

Lamp assembly with anisotropic heat spreader and vehicle having the same

A lamp assembly includes an outer lens, a lamp housing connected to the outer lens, a projector assembly having a projector lens, a lighting source, and an anisotropic heat spreader. The lighting source is adjacent to and partially within the projector assembly, and has a printed circuit board (PCB) connected to one or more light-emitting diodes, each emitting the light. The heat spreader, for instance a sheet of polycrystalline graphite, is connected to the PCB and extends beyond a surface area of the PCB into a lamp cavity. The heat spreader is configured to direct heat away from an LED junction toward a predetermined lower temperature zone of the lamp cavity. A vehicle includes a body and the lamp assembly.

Apparatus for radiating light from a virtual source
10422498 · 2019-09-24 · ·

A lighting assembly that includes an LED source that generates a light cone (solid angle); and a transparent near field lens having a front surface, a collimating surface, and an aspherical groove. The collimating surface collimates the light cone into a beam that reflects off of the front surface toward the aspherical groove, and the aspherical groove directs the beam away from the lens as an exit cone from a virtual focal point, positive virtual focal ring or a negative virtual focal ring. The exit cone may be evenly distributed, substantially forward or substantially rearward from the virtual focal point or virtual focal ring. Parabolic or aparabolic reflectors can be employed with lighting assemblies having a virtual focal point or virtual focal ring, respectively, to reflect the exit cone in a vehicular exterior lighting pattern.
