White light source device

A white light source device, comprising:

• a first light-emitting element having a first wavelength conversion unit and a first light-emitting unit in the first wavelength conversion unit, wherein the first light-emitting element emits a first light beam;
• and
• at least a second light-emitting element, wherein each of the second light-emitting elements has a second wavelength conversion unit and a second light-emitting unit in the second wavelength conversion unit, a top surface of the first wavelength conversion unit and a top surface of the second wavelength conversion unit are free from coverage of a molding structure, the second light-emitting element emits a second light beam, an emission spectrum of the second light beam is different from an emission spectrum of the first light beam, and each of the first light-emitting element and the second light-emitting element are spaced apart from each other;
• wherein the first light beam and the second light beam are mixed into a white light beam, and a color fidelity index of the white light beam is greater than 90.
