摘要:
A white LED module includes a circuit board, a blue LED chip disposed on the circuit board, a green light source of an LED chip or phosphor disposed on the circuit board, and a red light source of an LED chip or phosphor disposed on the circuit board. At least one of the green and red light sources is a phosphor, which is excited by the blue LED chip to radiate. The blue LED chip emits light in a triangular region defined by color coordinates (0.0123, 0.5346), (0.0676, 0.4633) and (0.17319, 0.0048), the green light source emits light in a triangular region defined by color coordinates (0.025, 0.5203), (0.4479, 0.541) and (0.0722, 0.7894), and the red light source emits light in a triangular region defined by color coordinates (0.556, 0.4408), (0.6253, 0.3741) and (0.7346, 0.2654).
