Abstract: A new ocular contact lens has been designed to increase the amount of light reaching the retina. The contact lens edge is chamfered to redirect and increase the light reaching the retina. A light source encircles and contacts the straight or curved chamfered edge. Additionally, a reflective cylinder and its top wall encircle the lens to block any loss of light. This distal edge of the contact lens may be rounded to increase the angle of retina visible. A new ocular imaging camera has a low-light camera subassembly with server, a photosensor next to low-light camera, a short cylindrical housing, a space between the camera subassembly and the housing, an internal program in server to detect good or poor image quality and an alarm for poor image quality, wherein an operator recaptures the image. A system has a highly efficient method to screen and diagnose a large number of patients using the new ocular contact lens and ocular imaging camera. The system receives and processes the photographs.

Abstract: An LED module for a luminaire has a downwardly directed heat sink comprising cooling fins that extend rearward from the module's front end and downward from its top wall, which has a top face that abuts the underside of a luminaire carrier plate. A circuit board carrying at least one LED is mounted on the front face, and a prism is mounted to the heat sink over the LED(s). The front (light-emitting) face of the catadioptric prism has several prominent side-by-side sections which emit beam patterns that diverge laterally and overlap in a central region.
