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.
Claims17
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,
- 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.
1 more element
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,
- the body is configured to be reversibly coupled with the luminaire using at least one reversible coupling mechanism, and
- 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.
1 more element
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;
- down converting 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, wherein the longer-wavelength light has a correlated color temperature (CCT) of between about 2700K to 4000K.
