Abstract:
A system and methods for light-emitting diode (LED) devices with a dimming feature that can tailor a color point shift in the light color temperature of a scattering/transparent layer to enlarge a dim to warm range are disclosed herein. A light-emitting device may include a wavelength converting structure configured to receive light from a light emitting semiconductor structure and an adjacent light scattering structure. The light scattering structure may comprise a plurality of scattering particles with a lower refractive index (RI) than the RI of the matrix material in which the scattering particles are disposed. The wavelength converting structure may include a red phosphor and a green phosphor such that to adjust overlap between green emission and absorption by the red phosphor to correspondingly adjust scattering and magnitude of color shift. In an embodiment, the light scattering structure may be integrated in the wavelength converting structure.

Claim (Index 1):
A light-emitting device configured to produce a white light comprising:\n a light emitting semiconductor structure configured to emit blue light at a first peak wavelength; a wavelength converting structure disposed in a path of the light emitted by the light emitting semiconductor structure and comprising a first phosphor material configured to absorb blue light at the first peak wavelength and in response emit green light at a second peak wavelength, and a second phosphor material configured to strongly absorb blue and green light with an absorption maximum between about 450 nanometers and about 500 nanometers and in response emit red light at a third peak wavelength; and a light scattering structure disposed in paths of light emitted by the light emitting semiconductor structure, the first phosphor material, and the second phosphor material, the light scattering structure comprising a plurality of scattering particles of a first material having a first index of refraction (n 1 ) dispersed in a second material having a second index of refraction n 2 , (n 2 \u2212n 1 ) having a larger magnitude at 25\u00b0 C. than at 100\u00b0 C., the light scattering structure arranged with respect to the wavelength converting structure to scatter back toward the first and second phosphor materials at least a portion of light emitted by the light emitting semiconductor structure, the first phosphor material and the second phosphor material.
