35. A method of fabricating a lighting device having a reduced total amount of phosphor, the method comprising the step of
providing a LED light source; -
providing a diffuser structure with an amount of phosphor, the diffuser structure configured for color mixing of the light from the LED light source and for spatially separating the amount of phosphor from the LED light source, whereby the amount of phosphor used is reduced at least 5 percent by weight compared to a similar lighting device having;
(i) the phosphor deposited on the LED light source and (ii) having substantially similar spatially correlated color temperature (CCT) variance or angular color homogeneity. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)
