Abstract

A signal guide for a sensor device is disclosed herein. The signal guide can include a base having a number of proximal apertures, where at least one of the proximal apertures is configured to be disposed proximate to at least one transceiver of the sensor device. The signal guide can also include a body disposed adjacent to the base, where the body includes at least one main channel, where the at least one main channel is configured to transmit at least one signal between the at least one main channel and the proximal apertures. The signal guide can further include a distal end disposed adjacent to the body opposite the base, where the distal end includes at least one distal aperture, where the at least one distal aperture is configured to transmit at least one signal between the a main channel and an ambient environment.

First claim

What is claimed is:

1. A signal guide for a sensor device of a light fixture, the signal guide comprising:
a base comprising at least one proximal aperture, wherein the at least one proximal aperture is configured to be disposed proximate to at least one transceiver of the sensor device, wherein the sensor device measures at least one parameter used to operate the light fixture for illuminating a volume of space;
a body disposed adjacent to the base, wherein the body comprises at least one main channel, wherein the at least one main channel is defined at a proximal end by the at least one proximal aperture; and
a distal end disposed adjacent to the body opposite the base, wherein the distal end comprises at least one distal aperture, wherein the at least one distal aperture defines a distal end of the at least one main channel, wherein the at least one distal end, the at least one main channel, and the at least one proximal aperture are configured to transmit at least one signal between the at least one transceiver and an ambient environment,
wherein the distal end is within a line of sight to a field of control in the ambient environment, wherein the field of control is a subset of the ambient environment,
wherein the distal end is configured to independently receive an ambient signal that originates within the field of control and fail to receive another ambient signal that originates outside the field of control,
wherein the ambient signal is configured to travel through the body and the base, wherein the body has a first cross-sectional shape and size that differs from a second cross-sectional shape and size of the base or the distal end so that the ambient signal that originates within the field of control is received and so that the another ambient signal that originates outside the field of control is not received,
wherein the first cross-sectional shape and size and the second cross-sectional shape and size are configured to define the field of control, and
wherein the at least one proximal aperture, the at least one main channel, and the at least one distal aperture are configured to deliver an undistorted version of the ambient signal from the field of control to the sensor device so that the sensor device accurately measures the at least one parameter.

2. The signal guide of claim 1 , wherein the at least one proximal aperture, the at least one main channel, and the at least one distal aperture are further configured to transmit at least one sensor signal that originates from the at least one transceiver of the sensor device to the ambient environment.

3. The signal guide of claim 1 , wherein the at least one distal aperture, the at least one main channel, and the at least one proximal aperture form a continuous channel.

4. The signal guide of claim 1 , wherein the at least one main channel comprises material that transmits the ambient signal between the at least one distal aperture and the at least one proximal aperture of a plurality of proximal apertures with substantially no loss or distortion.

5. The signal guide of claim 1 , wherein the at least one distal aperture comprises a plurality of distal apertures that are configured linearly with respect to each other at the distal end.

6. The signal guide of claim 1 , wherein the at least one main channel comprises a plurality of main channels, wherein the at least one proximal aperture comprises a plurality of proximal apertures, wherein each of the plurality of main channels and the plurality of proximal apertures are physically separated from each other within the body.

7. The signal guide of claim 6 , wherein the body has at least one physical gap separating the plurality of main channels and the plurality of proximal apertures.

8. The signal guide of claim 1 , wherein the at least one main channel is non-linear.

9. The signal guide of claim 1 , wherein the at least one distal aperture is substantially contiguous when the at least one distal aperture is a plurality of distal apertures.

10. A sensor device subassembly for a light fixture used to illuminate a volume of space, comprising:
at least one sensor comprising at least one transceiver, wherein the at least one transceiver sends or receives at least one signal, and wherein the at least one sensor measures at least one parameter used to operate the light fixture; and
a signal guide disposed adjacent to the at least one transceiver, wherein the signal guide comprises:
a base comprising at least one proximal aperture, wherein the at least one proximal aperture is disposed proximate to the at least one transceiver of the at least one sensor;
a body disposed adjacent to the base, wherein the body comprises at least one main channel that is defined at a proximal end by the at least one proximal aperture; and
a distal end disposed adjacent to the body opposite the base of the signal guide, wherein the distal end comprises at least one distal aperture that defines a distal end of the at least one main channel, wherein the at least one distal aperture, the at least one main channel, and the at least one proximal aperture transmit the at least one signal between the at least one transceiver and an ambient environment,
wherein the distal end is within a line of sight to a field of control in the ambient environment, wherein the field of control is a subset of the ambient environment,
wherein the distal end is configured to independently receive an ambient signal that originates within the field of control and fail to receive another ambient signal that originates outside the field of control,
wherein the ambient signal is configured to travel through the body and the base, wherein the body has a first cross-sectional shape and size that differs from a second cross-sectional shape and size of the base or the distal end so that the ambient signal that originates within the field of control is received and so that the another ambient signal that originates outside the field of control is not received,
wherein the first cross-sectional shape and size and the second cross-sectional shape and size are configured to define the field of control, and
