1. A light source device, comprising:

  • a substrate having an upper surface;

    at least one first light-emitting diode (LED) chip disposed on the upper surface and electrically connected to the substrate; and

    at least one second LED chip disposed on the upper surface and electrically connected to the substrate, wherein a first distance from the upper surface to a top surface of the at least one first LED chip is higher than a second distance from the upper surface to a top surface of the at least one second LED chip, and a thickness of the at least one second LED chip is different from a thickness of the at least one first LED chip,wherein the at least one first LED chip comprises a first chip substrate, the at least one second LED chip comprises a second chip substrate, and a thickness of the second chip substrate is different from a thickness of the first chip substrate.
