FIELD: lighting engineering, integrated circuits for microelectronics and electronic material science. SUBSTANCE: white light source built around blue-color nitridegallium light-emitting diode is so designed that blue light is partially converted into yellow light by means of luminescent converter assembled of single-crystalline piles on transparent substrate, then blue and yellow rays are mixed up to generated white light. EFFECT: enhanced efficiency of phosphor conversion, eliminated phosphor degradation, improved environmental friendliness. 6 cl, 5 dwg _
