Latest Patents

One of Steen's latest patents is for a White LED headlight. This innovative vehicle headlight employs a plurality of LED units that emit white light. Each LED unit utilizes chip-on-board technology, where LED semiconductor chips are mounted directly to a submount substrate using solder or stud bumps. An elongated lens is molded over the LED unit in contact with a base substrate. The light emitted from the semiconductor chip is reflected and directed by the lens to generate a beam of light. Additionally, some of the light emitted from the LED semiconductor chip is redirected back to the submount substrate to be reflected back into the lens, increasing the light intensity of the LED unit. Several of the elongated lenses and associated LED units are optically glued to a single prism that collects all of the light beams from all of the LED units.

Another significant patent is for a center high mounted stop lamp that includes a plurality of LEDs mounted on a printed circuit board. TIR lenses are employed to focus the light from the LEDs, providing an even lighting appearance. The TIR lenses include a prism for directing the light in a desired direction. The circuit board and lenses are mounted in a housing, ensuring that each LED includes a separate lens configured relative to it to provide the desired collection and reflectance of the light. The housing features a plurality of posts that extend through openings in the circuit board and the lenses to align the LEDs to the lenses relative to the housing.
