Patent ID: 8760057

Claim:
A far infrared ray ceramic bulb structure, comprising: a ceramic substrate having an upper surface and a lower surface; a light emitting element formed on a sapphire substrate and connected to the lower surface of the ceramic substrate; a far infrared thermal radiation film formed on the upper surface of the ceramic substrate, having a surface microscopic structure, and consisting of a mixture of metal and nonmetal; a circuit unit; a bulb shell; a bulb shade enclosing the light emitting element and the lower surface of the ceramic substrate; and a connector connecting the bulb shell and enclosing the upper surface of the ceramic substrate; wherein, the connector is connected to an external power source, the circuit unit is provided in the connector, the connector is connected to the circuit unit through a first electrical connection line to supply electrical power, the circuit unit is connected to the light emitting element through a second electrical connection line to transfer electrical signal(s) or supply electrical power used to drive or turn on the light emitting element, and the far infrared thermal radiation film propagates heat generated by the light emitting element and the circuit unit towards the lower surface of the ceramic substrate by thermal radiation consisting of at least far infrared ray.
