Abstract

An electrical device is described having surface mounting structure for mounting the electrical device in one of at least three different mounting patterns. In one embodiment, the electrical device is a lampholder having an occupancy sensor. In this embodiment, the occupancy sensor defines a coverage area and an un-coverage area when the lampholder is mounted to a surface, such as a ceiling, via the surface mounting structure; and, the surface mounting structure includes four sets of keyholes enabling the lampholder to be mounted to fasteners on the surface in one of a plurality of different mounting patterns for positioning the un-coverage area in a desired location, such as, for example, opposite the closest entry point to a room. The coverage area corresponds to a detection field of the occupancy sensor. Motion in the detection field is detected by the occupancy sensor.

Claims

1. A lampholder comprising:

a base having a lamp socket;

a sensor mounted on the base; and

surface mounting structure provided on the base for mounting the electrical device to a surface, wherein the surface mounting structure includes at least two sets of openings with each set having at least two openings.

2. The lampholder according to claim 1, wherein the at least two sets of openings each include at least one keyhole, and wherein each keyhole has a large end aperture and an elongated slot.

3. The lampholder according to claim 1, wherein the surface mounting structure is arranged and configured to enable the lampholder to be mounted to the surface in one of at least four different mounting patterns.

4. The lampholder according to claim 1, further comprising a lamp guard configured for being removably mounted to the base.

5. The lampholder according to claim 1, wherein the sensor is an occupancy sensor having a detection field, and wherein the lamp socket is disposed at least partially outside the detection field.

6. A lampholder comprising:

a base having a lamp socket;

a sensor provided on a first side of the base;

a lamp guard configured for being removably mounted to the first side of the base; and

surface mounting structure provided on a second side of the base for mounting the lampholder to a surface, wherein the surface mounting structure includes at least two sets of openings with each set having at least two opening.

7. The lampholder according to claim 6, wherein the at least two sets of openings each include at least one keyhole, and wherein each keyhole has a large end aperture and an elongated slot.

8. The lampholder according to claim 6, wherein the surface mounting structure enables the lampholder to be mounted to the surface in one of at least four different mounting patterns.

9. The lampholder according to claim 6, wherein the sensor is an occupancy sensor configured to define a coverage area and an un-coverage area when the lampholder is mounted to the surface, and wherein the lamp guard is at least partially is disposed outside the coverage area.

10. A method for mounting device lampholder to a surface, said method comprising the steps of:

providing lampholder comprising;

a base comprising a lamp socket, a sensor and mounting structure, the mounting structure being disposed on a first side of the base and being arranged and configured to mount the electrical device to a surface, wherein the mounting structure comprises at least two sets of openings each set having at least two openings, wherein the sensor is disposed on a second side of the base;

aligning at least one of the two sets of openings to a plurality of fastening locations in the surface; and

securing the electrical device to the surface by at least partially installing a plurality of fasteners in the fastening locations.

11. The method according to claim 10, wherein the at least one of the two sets of openings includes at least one keyhole, and wherein the keyhole has a large end aperture and an elongated slot, and further comprising the steps of:

rotating the electrical device to place at least one of the plurality of fastener within the elongated slot of the at least one keyhole.

12. The method according to claim 10, further comprising the step of selecting a mounting orientation for the lampholder from one of four different mounting orientations prior to the aligning step.
