Abstract
An LED package comprises an LED for emitting LED light, and a conversion material remote to said LED for down-converting the wavelength of LED light. The package further comprises a reflector directing at least some of the LED light toward the conversion material, the conversion material down-converting the wavelength of at least some of the reflected LED light. A method for emitting light from an LED package comprising providing an LED, reflector and conversion material, and emitting light from said LED, at least some of the LED light emitted toward the reflector. The method further comprises reflecting at least some of the LED light toward the conversion material, and converting at least some of said reflected LED light at the conversion material. At least some of the converted reflected LED light is emitted by the LED package.
