Abstract

A light system may include a luminaire comprising one or more light emitters and at least one optic. The light system may include a remote phosphor mask that is reversibly coupled with the luminaire using at least one reversible coupling mechanism. The remote phosphor mask may include one or more phosphors admixed with an optical material. The one or more phosphors may be capable of adjusting a color temperature of emitted light from the luminaire.

First claim

What is claimed is:

1 . A light system comprising:
a luminaire comprising one or more light emitters and at least one optic; and a remote phosphor mask that is reversibly coupled with the luminaire using at least one reversible coupling mechanism, the remote phosphor mask comprising one or more phosphors admixed with an optical material, wherein the one or more phosphors are capable of adjusting a color temperature of emitted light from the luminaire.

2 . The light system of claim 1 , wherein:
the remote phosphor mask is disposed outward of the at least one optic.

3 . The light system of claim 1 , wherein:
the remote phosphor mask is disposed between the one or more light emitters and the at least one optic.

4 . The light system of claim 1 , wherein:
a light emission portion of the remote phosphor mask comprises at least one contour that conforms to a three dimensional shape of one or both of the one or more light emitters and the at least one optic.

5 . The light system of claim 4 , wherein:
the at least one contour comprises a projection that defines at least one cavity; and the at least one cavity receives at least a portion of one or both of the one or more light emitters and the at least one optic.

6 . The light system of claim 1 , wherein:
the at least one reversible coupling mechanism comprises an adhesive.

7 . The light system of claim 1 , wherein:
the at least one reversible coupling mechanism is selected from the group consisting of a fastener, a clamp, an interference fit connection, a press fit connection, a clip, and a snap.

8 . The light system of claim 1 , further comprising:
a base that supports the one or more light emitters and the at least one optic; and an outer frame that extends over a portion of the remote phosphor mask and couples with the base to secure the remote phosphor mask to the luminaire.

9 . A remote phosphor mask for a luminaire, comprising:
a body formed of an optical material admixed with one or more phosphors, the body comprising a light emission portion, wherein:
the one or more phosphors are capable of adjusting a color temperature of emitted light from the luminaire, and
the body is configured to be reversibly coupled with the luminaire using at least one reversible coupling mechanism.

10 . The remote phosphor mask for a luminaire of claim 9 , wherein:
the remote phosphor mask is configured to be positioned remote from a light emitter of the luminaire.

11 . The remote phosphor mask for a luminaire of claim 9 , wherein:
the light emission portion of the remote phosphor mask comprises at least one contour that conforms to a three-dimensional shape of one or both of a light emitter and an optic of the luminaire.

12 . The remote phosphor mask for a luminaire of claim 9 , wherein:
the at least one reversible coupling mechanism comprises an adhesive applied to an inner surface of the remote phosphor mask.

13 . The remote phosphor mask for a luminaire of claim 9 , wherein:
the at least one reversible coupling mechanism is selected from the group consisting of a fastener, an aperture for receiving a separate fastener, a clamp, an interference fit connector, a press fit connector, a clip, and a snap.

14 . The remote phosphor mask for a luminaire of claim 9 , wherein:
the light emission portion of the remote phosphor mask has a substantially uniform thickness.

15 . A method of using a remote phosphor mask, comprising:
providing a remote phosphor mask on a luminaire, wherein:
the remote phosphor mask includes one or more phosphors; and
the remote phosphor mask is reversibly coupled with the luminaire using at least one reversible coupling mechanism;
emitting light from light emitters of the luminaire, wherein at least a portion of the light includes a shorter-wavelength light; absorbing, by the one or more phosphors in the remote lighting mask, at least a subset of the shorter-wavelength light; downconverting the subset of the shorter-wavelength light to longer-wavelength light; and emitting, by the one or more phosphors in the remote lighting mask, longer-wavelength light.

16 . The method of using a remote phosphor mask of claim 15 , wherein:
the longer-wavelength light has a correlated color temperature (CCT) of between about 2700K to 4000K.

17 . The method of using a remote phosphor mask of claim 15 , wherein:
the shorter-wavelength light has a correlated color temperature (CCT) of at least 5000K.

18 . The method of using a remote phosphor mask of claim 15 , further comprising:
generating a predetermined light distribution by passing light emitted from the light emitters through at least one optic.

19 . The method of using a remote phosphor mask of claim 18 , wherein:
the light emitted from the light emitters is passed through the at least one optic prior to being absorbed by the one or more phosphors.

20 . The method of using a remote phosphor mask of claim 18 , wherein:
the light emitted from the light emitters is passed through the at least one optic after being absorbed emitted by the one or more phosphors.
