ITC has filed a patent for a light projector assembly that includes a projector integrated with a light bar. The projector and light bar share power and control wires from a wire harness. The projector has a projector aperture that allows light to pass through and direct onto a ground surface. The light assembly is clear and sealed to protect the projector and lens components. The assembly also reduces the number of wires and parts, resulting in cost savings for vehicles. GlobalData’s report on ITC gives a 360-degree view of the company including its patenting strategy.

The patent filed is for a light projector assembly
A recently filed patent (Publication Number: US20230125300A1) describes a light projector assembly that offers several innovative features and cost-saving measures. The assembly consists of a projector connected to a light bar, with both sharing power and control wires from a wire harness. The projector has a projector aperture that allows light to pass through and project onto a ground surface. The light assembly within the projector is clear and sealed to protect the projector and lens components. By reducing the number of wires and implementing a pass-through power configuration, the assembly reduces the number of parts and overall cost to the vehicle.
One notable feature of the light projector assembly is the inclusion of a lens stack, which includes a collimation lens set, an image slide, and a zoom and aberration lens set. The lens stack has a minimized or reduced height size and offers customization options with preferred logos and patterns for projection onto the ground surface. A cover is configured to house and cover the light assembly, with endcaps covering both the front and rear portions of the assembly to retain it onto the end of the light bar. Potting material is used inside the cover to seal the assembly from external environmental conditions.
The patent also highlights the direct soldering of power source wires to a printed circuit board in the projector housing. One power source wire is soldered directly to the board, while the second power source wire extends to the light bar. This soldering arrangement further simplifies the wiring and reduces the number of components required, contributing to cost savings for the vehicle.
Overall, this light projector assembly patent introduces various improvements and cost-saving measures. The integration of a lens stack, customizable image slide, and sealed light assembly enhances the functionality and durability of the projector. The reduction in wires and implementation of a pass-through power configuration contribute to a simplified design and lower costs for the vehicle.
