Abstract
A radiation monitor for a lighting device, and operating methods and systems therefor are provided. In one example, a radiation monitor may include a first sensor receiving radiation output directly from a light-emitting element of the lighting device and radiation output from external sources; and a second sensor receiving the radiation output from the external sources without receiving the radiation output directly from the light-emitting element of the lighting device. The radiation monitor may determine an intensity of the radiation output directly from the light-emitting element based on a difference in the output signals from the first sensor and the second sensor.
