Abstract: A wavelength conversion device and a light source system, including: a substrate; a first light-emitting portion disposed on the substrate, wherein the first light-emitting portion includes a first light guide area and a counterweight area provided on the same layer as the first light guide area, the first light guide area being used for guiding first light, and the counterweight area being used for making the weight distribution of the wavelength conversion device substantially uniform; and a second light-emitting portion provided on the substrate on the same side as the first light-emitting portion, the second light-emitting portion including a conversion area, and the conversion area being used to convert at least a part of excitation light into excited light for emission when the excitation light is received.
