OPTICAL DEVICE WITH SENSOR AND METHOD OF MAKING AND USING SAME

摘要

Optical devices (100) that contain a sensor (140) are described. More particularly, optical devices that contain a light source (120), cavity (110) and sensor (140), in which the optical device (100) may provide an optimal light output from an output surface (112) of the cavity (110) based on various characteristics of the light are described. Additionally, methods of making and using such optical devices as well as arrays of such optical devices are disclosed.
