    Abstract: A lighting apparatus includes a circuit board having a highly reflective top surface; at least one LED chip mounted on the top surface of the circuit board, the at least one LED chip being operable to emit light of a first color. A phosphor film having an arcuate inner surface is configured to maintain a predetermined finite distance from the at least one LED chip, the phosphor film being disposed such that light emitted from the LED chip radiates upon the phosphor film, the inner surface of the phosphor film hooding the top surface of the circuit board so as to form a multi-reflection zone to reduce light absorption by the at least one LED chip and reduce direct light leakage from between the phosphor film and the top surface of the circuit board. The phosphor film containing phosphors that down convert at least a portion of the light of the first color into light of a second color, that when mixed together with the first color produces visible white light.
