Lighting fixture with image sensor
First Claim
1. A lighting fixture comprising:
- a solid state lighting source that is responsive to a drive signal;
an image sensor configured to capture an image during an image capture period in response to an image capture signal; and
a control system configured to;
during an on state, control the drive signal such that light for general illumination is emitted from the solid state lighting source;
during an off state, control the drive signal such that no light for general illumination is emitted from the solid state lighting source; and
when capturing the image;
provide the image capture signal; and
control the drive signal such that light for image capture is continuously emitted from the solid state lighting source throughout the image capture period, wherein images are captured at different times throughout the on state and the off state and the light for general illumination differs from the light for image capture by at least one characteristic during the off state.

Abstract
A lighting fixture with a control system, a light source, and an image sensor is disclosed. The image sensor is configured to capture an image in response to an image capture signal. The light source emits light in response to a drive signal. The control system provides the drive signal to control the light emitted by the light source, and when an image needs to be captured, provides the image capture signal. When capturing an image, the control system may coordinate the drive signal and the image capture signal so that the image sensor captures the image when the light source is emitting light, if light is needed or desired. The control system may control the drive signal to control the light emitted by the light source or control other lighting fixtures in the lighting network based, at least in part, on information derived from one or more captured images.

27. A lighting fixture comprising:
-
a solid state lighting source that is responsive to a pulse width modulated drive signal, wherein each cycle of the pulse width modulated drive signal has an active portion in which light for image capture is continuously emitted and an inactive portion in which the light for image capture is not emitted; an image sensor configured to capture an image during an image capture period in response to an image capture signal; and a control system configured to; during an on state, control the pulse width modulated drive signal such that light for general illumination is emitted from the solid state lighting source; during an off state, control the pulse width modulated drive signal such that no light is emitted from the solid state lighting source; and when capturing the image, provide the image capture signal such that the image capture period falls within the active portion of the pulse width modulated drive signal. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)
