Abstract
A source of white light constructed of a vacuum glass chamber, containing an optically active element, a generator of an IR electromagnetic radiation beam equipped with a laser IR diode, a battery, a focusing lens, and, optionally, a reflector characterized in that the optically active element contained in the vacuum chamber is a thin layer graphene matrix with the thickness of up to 3 mm Embodiments also relate to a method of white light generation by the above-mentioned white light source.
Claims6
A white light source comprising:
- a vacuum glass chamber containing an optically active element, a generator of an IR electromagnetic radiation beam equipped with a laser IR diode, a battery, a focusing lens, and, a reflector, wherein the optically active element contained in the vacuum chamber is a thin layer graphene matrix with the thickness of up to 3 mm wherein after excitation by means of the beam of radiation generated by the laser IR diode, the optically active element emits white light with the color rendering index (CRI) above 96, wherein the excitation power of 0.3-0.6 W is generated by means of an electromagnetic radiation beam generator, after which the exciting beam is passed through the focusing lens and then directed onto the graphene matrix at the angle of 45-90° in relation to the matrix surface, which, as a result of excitation, emits radiation in the white light range.
