  • the switch 631 can be any of a number of types of switches, including but not limited to one or more DIP switches, one or more SIPP switches, one or more rocker switches, one or more reed switches, one or more magnetic switches, one or more rotary switches, one or more rotary dials, one or more selectors or selector switches, one or more slide switches (as shown in Figure 6C), one or more snap switches, one or more thumbwheels, one or more toggles or toggle switches, one or more keys or keypads, and one or more buttons or pushbuttons.
  • the switch 631 of Figures 6A-6C is a slide switch.
  • the switch 631 has a body 671 and a number of coupling features 672 (in this case, pins) disposed on the bottom of the body 671 that allow the switch 631 to become electrically coupled to an electrical connector 629 on the substrate 625 (and therefore also to one or more of the other components 663 mounted on the substrate 625, such as a controller, as described above).
  • adjacent to the coupling features 672 can be disposed one or more mechanical coupling features 679 (e.g., tabs, posts).
  • mechanical coupling features 679 can act as guides to properly position and align the coupling features 672 of the switch 631 relative to an electrical connector 629 mounted on the substrate 625.
  • an actuator 673 that extends outward from a plate 676.
  • the plate 676 is disposed within the body 671 and has a length that is less than the length of the body 671.
  • the plate 676 also corresponds to a slot 674 that traverses the top end of the body 671.
  • the actuator 673 extends through the slot 674 and can be accessible by a user.
  • the switch 631 can include a number of detents and/or other features to limit or create discrete stopping locations for the actuator 673 (and so also the plate 676) along the length of the slot 674.
  • Each of these detents and/or other features can be associated with a certain value of a variable that affects the operation of the luminaire 600. For example, if the switch 631 is used to select a CCT, the left end 681 of the slot 674 can be associated with 5000 K, detent 682 can be associated with 4000 K, detent 683 can be associated with 3500 K, detent 684 can be associated with 3000 K, and right end 685 of the slot 674 can be associated with 2700 K.
  • Example switches 631 can be used with a new luminaire 600.
  • example switches 631 can be retrofit into existing luminaires.
  • Figures 6A-6C show that the switch 631 is disposed within and coupled to the housing 605, the switch 631 can alternatively be disposed within and/or coupled to some other portion (e.g., the trim 610) of the luminaire 600.
  • a luminaire can be manufactured without the switch, but with the ability to receive an example switch at a later time (e.g., during installation).
  • Figure 7 shows a luminaire 700 that is configured to receive a switch in accordance with certain example embodiments. Referring to Figures 1A-7, the luminaire 700 can be substantially the same as the luminaires discussed above, except as described below.
  • the luminaire 700 of Figure 7 can include an housing 705 that is cylindrical in shape, having a top surface 706 and a side surface 707. Coupled to the bottom end of the housing 705 of Figure 7 can be a trim 710. Further, hanger clips 702 can be used to hold the luminaire 700 in place upon installation. In this case, the example switch is not coupled to the luminaire 700. Instead, there is a removable plug 789 disposed in the aperture 775 that traverses the top surface 706 of the housing 705. The removable plug 789 can be used to keep dust and other elements in the ambient environment from entering the cavity formed by the housing 705.
  • Example switches can be incorporated into any of a number of different types of luminaires (light fixtures). For example, as shown in Figures 6A-7, example switches can be used with down light fixtures.
  • luminaires that can be used with example switches can include, but are not limited to, troffer lights, under cabinet lights, pendent lights, recessed lights, and wall scones, [0066] As will be appreciated by those of ordinary skill, the textual and illustrated disclosure provided herein supports a wide range of embodiments and implementations.
  • a luminaire can comprise: a housing; a substrate disposed in the housing; a first plurality of light emitting diodes that are mounted to the substrate and that have a first color temperature; a second plurality of light emitting diodes that are mounted to the substrate and that have a second color temperature; and a plurality of manual switches that are disposed at the housing for permanently configuring the luminaire to: provide illumination of the first color temperature by enabling the first plurality of light emitting diodes; provide illumination of the second color temperature by enabling the second plurality of light emitting diodes; and provide illumination of a third color temperature that is between the first color temperature and the second color temperature by enabling the first plurality of light emitting diodes and the second plurality of light emitting diodes.
