Improvements in the construction of electric heating devices, characterized in that the electrical resistance, adequate to develop the minimum of light energy, is placed in two helices, in a refractory of two entrances, placed exactly in the focus of a parabolic screen, and is protected by a molten grid; a switch for connection to 120 or 220 volts is inserted in the resistance circuit.
