Patent abstract
A light emitting apparatus (8) includes one or more light emitting chips (10) that are disposed on a printed circuit board (12) and emit light predominantly in a wavelength range between about 400 nanometers and about 470 nanometers. The printed circuit board includes: (i) an electrically insulating board (14); (ii) electrically conductive printed circuitry (20); and (iii) an electrically insulating solder mask (22) having vias (24) through which the one or more light emitting chips electrically contact the printed circuitry. The solder mask (22) has a reflectance of greater than 60% at least between about 400 nanometers and about 470 nanometers.
