Abstract
A light emitting device with selective reflection function being applied to general light emitting device and AC-type light emitting device is revealed. The light emitting device includes at least one vertical light emitting unit, at least one selective reflection layer and a phosphor layer. The selective reflection layer is disposed over the vertical light emitting unit and the phosphor layer is arranged over the selective reflection layer. Thus first colored light from the vertical light emitting unit passes the selective reflection layer and then to be converted into second colored light by the phosphor layer. The selective reflection layer reflects the second colored light while the first colored light is mixed with the second colored light to form mixing colored light. By the selective reflection layer that prevents the second colored light emitting into the light emitting unit, the lighting efficiency of the light emitting device is enhanced.
