Patent ID: 8162506

Claim:
An illuminating apparatus comprising: a light source comprising a substrate and at least one light emitting diode arranged on the substrate; a supporting member connected to the substrate, the supporting member comprising a light emitting surface at a side thereof distant from the at least one light emitting diode; a first film and a second film attached to each other and arranged at the light emitting surface of the supporting member, the first film comprising a first phosphor doped therein, the second film comprising a second phosphor doped therein, each of the first phosphor and the second phosphor capable of being excited by light emitted from the at least one light-emitting diode and converting a wavelength of the light into a desired wavelength; wherein the first film further comprises a third phosphor, the first film defines a plurality of first regions arranged in an array, the first phosphor is doped into every odd-numbered first region in a sequence of the first regions, and the third phosphor is doped into every even-numbered first region in the sequence of the first regions; wherein the second film further comprises a fourth phosphor, the second film defines a plurality of second regions arranged in an array, the second phosphor is doped into every odd-numbered second region in a sequence of the second regions, and the fourth phosphor is doped into every even-numbered second region in the sequence of the second regions; and wherein the first regions of the first film are respectively directly opposite to the second regions of the second film.
