Claim of US Patent No. 10,045,414

1. A method for increasing the luminous intensity of an ultraviolet light emitting diode, comprising:mounting the ultraviolet light emitting diode on a substrate, with an electric heater mounted on the substrate;
using a controller to control the electric heater to heat the ultraviolet light emitting diode through the substrate, and using a temperature sensor to detect a temperature of the ultraviolet light emitting diode;
using the controller to supply electricity to the ultraviolet light emitting diode when the ultraviolet light emitting diode reaches a working temperature; and
making the ultraviolet light emitting diode to emit an ultraviolet light.
