Abstract
A hand held light having a light assembly is disclosed having a substrate carrying a light emitting element. A phosphor layer is disposed atop the substrate and light emitting element. A photoluminescent layer is disposed atop the phosphor layer.
Claims21
A hand held light having a light assembly, the light assembly comprising:
- a substrate carrying a light emitting element, said light emitting element coupled to a power source;
- a phosphor layer disposed atop the substrate and light emitting element, encapsulating the lighting emitting element such that all light emitted from the light emitting element passes through, or is attenuated by the phosphor layer, wherein the phosphor layer comprises a luminescent formulation configured to convert light emitted from the light emitting element to white light;
- and
- a photoluminescent layer disposed about the phosphor layer such that light emitted from the light emitting element that passes through the phosphor layer passes through or is attenuated by the photoluminescent layer, wherein the photoluminescent layer comprises a photoluminescent formulation.

A hand held light having a light assembly, the light assembly comprising:
- a substrate carrying a plurality of light emitting element, said light emitting elements coupled to a power source;
- a phosphor layer disposed about the substrate and a first portion of the plurality of light emitting elements, encapsulating the first portion of the plurality of lighting emitting elements such that all light emitted from the first portion of the plurality of light emitting element passes through, or is attenuated by the phosphor layer, wherein the phosphor layer comprises a luminescent formulation configured to convert light emitted from the first portion of light emitting elements to white light;
- and
- a photoluminescent layer disposed about a second portion of the plurality of light emitting elements such that all light emitted from the second portion of the plurality of light emitting elements passes through or is attenuated by the photoluminescent layer.

A method of propagating light through a light assembly, comprising:
- providing power to a light emitting element disposed about a substrate, resulting in the propagation of a wavelength of light from the light emitting element;
- propagating the wavelength of light through a phosphor layer, converting the wavelength of light into white light;
- propagating a portion of the converted wavelength of light through a photoluminescent layer disposed adjacent the phosphor layer.
- exciting photoluminescent material within the photoluminescent layer from the photoluminescent layer;
- and
- propagating photoluminescent light from the photoluminescent layer.

A lighting assembly, comprising:
- a substrate carrying a plurality of light emitting element, said light emitting elements coupled to a power source;
- a photoluminescent layer disposed about the substrate wherein the photoluminescent layer comprises a luminescent formulation configured to convert light emitted from the light emitting elements to white light;
- and
- wherein the a photoluminescent layer comprises a photoluminescent formulation having a fluorescent material or a phosphorescent material therein.
