  • Modular LED imaging projector and optical systems
    Patent number: 11611730
    Abstract: The disclosure relates to modular LED imaging projector and optical systems and apparatuses. A light-emitting diode (LED) engine module emits a light beam that is homogenized and focused through a predetermined focal point. The LED engine module is detachably attached to a posterior connection point of a base body assembly. A collimating lens within the base body assembly refocuses the light beam to reduce divergence.
    Type: Grant
    Filed: February 11, 2021
    Date of Patent: March 21, 2023
    Inventors: Brian Robert Moon, John W. Luhrs
  • Lens-fitted retrofit LED lamp system
    Patent number: 11421830
    Abstract: The disclosure describes systems and methods for retrofitting a light fixture using a lens-fitted retrofit assembly. The lens-fitted retrofit assembly is attached anterior to the LED lamp engine. A lens-fitted retaining adapter of the lens-fitted retrofit assembly includes at least one curved portion that matches a radius of curvature of a lens holder of the light fixture. The lens-fitted retrofit assembly is held into the light fixture based at least in part on the lens-fitted retaining adapter and the lens holder.
