Abstract: A light emitting apparatus receives an external power. A switching unit is electrically connected with a light emitting unit to form a serial circuit. A first electrical connection element is electrically connected with the external power and the light emitting unit. A second electrical connection element is electrically connected with the external power and the switching unit. A sensing unit is electrically connected with the first electrical connection element, the second electrical connection element and the switching unit.

Abstract: A device for heating a substrate with light from a flash lamp having a semiconductor switch connected in series to the flash lamp. After triggering of a trigger electrode of the flash lamp, a first drive signal and a second drive signal are output from a gate circuit. The time period when the semiconductor switch is on due to the second drive signal is longer than the time period that the semiconductor switch is on by the first drive signal. Then, the semiconductor switch is switched on and off by the first drive signal and the substrate temperature is increased to a temperature, which is lower than the desired temperature to be targeted, and is maintained a that temperature for a short time, after which the surface temperature of the substrate is increased to the desired target temperature.
