发明名称 Multiple conversion material light emitting diode package and method of fabricating same
摘要 An emitter package comprising a light emitting diode (LED) emitting light at a wavelength within a wavelength range and a plurality of phosphors. Each of the phosphors absorbs at least some light from the LED and re-emits a different wavelength of light. The package emits a combination of light from the LED and the plurality of phosphors, with the phosphors having excitation characteristics such that the emitter package emits light within a standard deviation of a target color for LEDs emitting at the wavelengths with the wavelength range. A method for fabricating emitter packages comprising fabricating a plurality of LEDs, each of which emits at a wavelength within a range of wavelengths. Each of the LEDs are arranged in a respective package with a plurality of conversion materials so that at least some light from each of the LEDs is absorbed and re-emitted by its corresponding conversion materials. The plurality of conversion materials have excitation characteristics that compensate for different LED emission wavelengths within the LED range of wavelengths such that each of the LED packages emits light within a standard deviation from a target color.
