Abstract
A sensor module is integrated into a lighting fixture. The sensor module includes one or more environmental sensors and can be readily installed in or removed from the lighting fixture. In one embodiment, a heatsink of the lighting fixture is configured to receive the sensor module. Readings from the environmental sensors may be passed to control electronics associated with the lighting fixture and used to control the light output of the lighting fixture. The readings may also be passed on to other lighting fixtures, which may also use the readings to control their light output.
Claims26
A lighting fixture comprising:
- a main structure;
- a light source provided within the main structure and configured such that light emitted from the light source is directed out of the main structure toward an illuminated area;
- a heatsink coupled to the lighting fixture below the main structure and thermally coupled to the light source, the heatsink having an internal surface, which houses the light source and is exposed to the main structure, and an external surface, which is opposite the internal surface and is exposed to the illuminated area;
- and
- a sensor module coupled to the external surface of the heatsink such that the sensor module is below the heatsink.
A sensor module for a lighting fixture housing a light source on a top surface of a heatsink, the sensor module comprising:
- a housing;
- at least one environmental sensor exposed through the housing;
- a lens attached to the housing and covering the at least one environmental sensor;
- and
- a connection mechanism configured to engage a bottom surface of the heatsink, which is opposite the top surface.
