This emission characteristic is useful for applications like displays which require large viewing angles. For applications requiring a more brilliant emission characteristic it is necessary to place an optical lense in front of the LED.
The innovation presented herein, provides a new type of (white) light source with a most brilliant emission characteristic for applications which need brilliant white-light, e.g. automobile headlights.
The innovation uses amorphous materials composed of symmetry-free, diamondoid-like cluster molecules which are readily available from ubiquitous resources instead of phospors for the conversion of infrared (IR) light into white-light. The emission characteristic of the original IR-light is to a great extent pre-served, so that by use of, e.g., IR-Laser-diodes the brilliancy of the IR-excitation-light is preserved within the emitted white-light, resulting in an extraordinary brilliant source of white-light.
The invention can be applied advantageously in any application that needs brilliant white-light, e.g. headlights of any type, microscopes, projecting systems etc., within science, technology and economy (optoelektronics / illuminating engineering).
The excitation frequency of the new method for the conversion of invisible light into visible white-light is using infrared light instead of ultraviolet light. The brilliancy of the excitation light-source is maintained throughout the whole conversion process so that, e.g. by use of an IR-laser-diode as source of excitation light, the brilliancy of the original laser light is preserved within the finally emitted white-light.
The method has been proven to work on laboratory scale by use of IR-laser-diodes as source of excitation light, but will also work with any other source of IR-light.
Currently the area of illuminating technology experiences a fundamental upheaval by use of LED-technology. By providing convenient access to most brilliant white-light LEDs, the technology presented herein is expected to have great market potential.
