Electric heat apparatus used for heating food, for use in house, has one radiation source that is adapted to be electrically energized and operated, and another radiation source that is adapted to be excited by one radiation

摘要

The electric heat apparatus (10) has a radiation source (20) which emits one radiation with one wavelength, when exciting the radiation source (20). The radiation source (22) emits another radiation with another wavelength, when exiting the radiation source (22). The radiation source (20) is adapted to be electrically energized and operated. Another wavelength is greater than one wavelength. The radiation source (22) is adapted to be excited by one radiation. The radiation source (22) is designed to generate population inversion, when excited by one radiation.
