PHOSPHOR-CONVERTED LIGHT EMITTING DIODE DEVICE |
摘要 |
A light emitting diode is provided which is capable of emitting a first light having a first peak wavelength. The light emitting diode is provided with a phosphor layer overlying the light emitting diode and capable of absorbing the first light and emitting a second light having a second peak wavelength. The phosphor layer includes a pattern of holes positioned to allow the first peak wavelength to exit through the holes without being absorbed by the phosphor layer, and wherein the holes are placed to facilitate more of the first peak wavelength to exit the phosphor in the area of the holes than the second peak wavelength.
