Light source with light sensor

摘要

There are provided systems, devices and methods for operating a light source with a light sensor to provide a desired light output. In particular, in one embodiment, there is provided a light control system. The light control system includes a light source and a light sensor that share a common light pathway. Additionally, the light control system includes a controller electrically coupled to the light source and the light sensor. The controller operates the light source and the light sensor alternatively during a periodic cycle having a frequency of approximately 60 Hz or greater to achieve a desired visual effect based on ambient lighting conditions.

1. A light control system for an electronic device, comprising:
a light source; a light sensor separate from the light source and configured to sense ambient light levels; a light pathway shared by the light sensor and the light source; a controller communicatively coupled to the light source and the light sensor, the controller configured to alternately activate the light source and the light sensor during a periodic cycle to illuminate at least a portion of the electronic device, wherein the controller activates the light sensor after a predetermined delay following deactivation of the light source and wherein the controller dynamically adjusts an output of the light source during the periodic cycle based on a sensed amount of ambient light present after the predetermined delay; and the light source and light sensor are disposed on a planar surface of a common substrate.
