Abstract: According to one aspect, a thermal protection device is provided having an electrical input for receiving input DC power and an electrical output for connection to a load. A heating circuit is coupled to the electrical input for developing one of first and second different heat magnitudes depending upon a temperature magnitude in the housing. An additional circuit is in thermal communication with the heating circuit for providing output DC power to the electrical output when the first heat magnitude is developed and for interrupting the output DC power when the second heat magnitude is developed.

Abstract: A sensor module for a lighting fixture includes a light sensor and a sensor cover over the light sensor. The sensor cover includes a front surface and a light focusing surface opposite the front surface. The front surface is configured to face an area of interest that is generally illuminated by the lighting fixture. The light focusing surface is opposite the front surface and includes a number of lens sections, each of which is configured to focus light from a different portion of the area of interest toward the light sensor. By including a number of lens sections each focusing light from a different portion of the area of interest, a relatively large area of interest can be observed while maintaining desirable aesthetics of the sensor module.
