The invention concerns a devicefor illuminating an objectwith a controlled light intensity, the light intensity being controlled when the light intensity fulfills a plurality of conditions to be fulfilled, the plurality of conditions comprising a condition relative to the intensity at a given time and a condition relative to the dose during a period of time.

Device for illuminating an object with a controlled light intensity and associated method

The present invention concerns a medical device () intended to be worn by a human wearer, the medical device () defining a first area () and a second area (), each area being intended to be positioned in front of a respective eye of the wearer. The medical device () comprises a frame (), comprising a rear shell (). The rear shell () defines a hole () facing the first area () and the rear shell () is opaque facing the second area (). The medical device () also comprises an optical module () in the first area (). The optical module () comprises a light source () and an optical system (). The optical module () is arranged to send a light beam through the hole (). The medical device () further comprises an electronic circuitry (), adapted to command the optical module ().

Medical device intended to be worn in front of the eyes

A pixel cell circuit comprises an electrode, one or more main photosensitive elements electrically coupled to the electrode for outputting a stimulation signal to the electrode responsive to light illumination, and a shunt arrangement comprising a shunt switch electrically coupled in parallel across the one or more photosensitive elements, and a control arrangement operatively coupled to the shunt switch and configured for placing the shunt switch in an open state responsive to incident light received at the pixel cell and placing the shunt switch in a closed state if no incident light is received at the pixel cell.
