Abstract:
1. A light source device, comprising: a plurality of light-emitting diodes (LEDs), chromaticities of a part of the LEDs falling in a first area of a chromaticity coordinate diagram, while chromaticities of the other LEDs falling in a second area of the chromaticity coordinate diagram, the second area and the first area being point symmetric to a first white center of the chromaticity coordinate diagram, a chromaticity coordinate value farthest from the white center in the first area being (X a carrier, the LEDs being disposed on the carrier, and a chromaticity difference of any two adjacent LEDs in the chromaticity coordinate diagram being (ΔX, ΔY), wherein |ΔX|≦0.01 and |ΔY|≦0.01.
