Abstract
A method for increasing the luminous intensity of an ultraviolet light emitting diode includes heating an ultraviolet light emitting diode to a working temperature, and supplying electricity to the ultraviolet light emitting diode at the working temperature to make the ultraviolet light emitting diode emit ultraviolet light. An apparatus for increasing the luminous intensity of an ultraviolet light emitting diode includes a substrate, an ultraviolet light emitting diode mounted on the substrate, an electric heater mounted on the substrate, a temperature sensor, and a controller electrically connected to the ultraviolet light emitting diode, the electric heater, and the temperature sensor. The controller can heat the ultraviolet light emitting diode through the substrate. When the temperature sensor detects that the temperature of the ultraviolet light emitting diode reaches a working temperature, the controller supplies electricity to the ultraviolet light emitting diode to make the ultraviolet light emitting diode emit ultraviolet light.
