    摘要： A segmented light or optical power emitting device and an illumination device are described. The segmented device includes a die having a light or optical power emitting semiconductor structure that includes an active layer disposed between an n-layer and a player. Trenches are formed in at least the semiconductor structure and separate the die into individually addressable segments. The active layer emits light or optical power having a first color point or spectrum. At least one wavelength converting layer is adjacent the die and converts the light or optical power to light or optical power having at least one second color point or spectrum and limits an energy ratio of the pump light or optical power that passes through the at least one wavelength converting layer unconverted to total light or optical power emitted by the light or optical power emitting device to less than 10%.
