Abstract
An LED device comprises an LED chip or LED chip array for emitting light of a color spectrum, the LED chip or array being mounted on a component having a component surface. At least one color is applied to the component surface where the color is selected to reflect light to color tune the light emitted from the LED device to obtain a desired CRI.
Claims25
An LED device comprising:
- an LED for emitting light, the light comprising at least one color constituent of a color spectrum, the LED mounted on a component having a component surface;
- a non-white colorant of a first color applied to the component surface where the color is in the color spectrum of the at least one color constituent wherein the colorant is not disposed over the LED.
An LED device comprising:
- a plurality of LED chips each of the LED chips emitting light of a color spectrum, the plurality of LED chips mounted on a component having a component surface;
- a non-white colorant applied to the component surface where the colorant is in the color spectrum of at least one of the plurality of LED chips wherein the colorant is not disposed over the plurality of LED chips.
An LED device comprising:
- an LED chip for emitting light of a color spectrum, the LED chip mounted on a component having a component surface;
- a non-white colorant applied to the component surface where the colorant is selected to reflect non-white light that is mixed with the light emitted from the LED chip to color tune the light emitted from the LED device to obtain a desired CRI wherein the colorant is not disposed over the LED chip.
An LED device comprising:
- an LED chip for emitting light of a color spectrum, the LED chip mounted on a component having a component surface;
- a non-white colorant applied to the component surface where the colorant is in a second color spectrum that is different than the color spectrum wherein the colorant is not disposed over the LED chip.
An LED device comprising:
- an LED chip for emitting light of a color spectrum, the LED chip mounted on a component having a component surface;
- a non-white colorant applied to the exposed surface where the colorant is selected to reflect light to color tune the light emitted from the LED device to obtain a desired CRI wherein the colorant is not disposed over the LED chip wherein the colorant matches the light emitted from the LED device.
