POLYCHROMATIC ELECTROLUMINESCENT DEVICE

摘要

Several elementary light sources are connected in series and energized simultaneously to emit electroluminescent radiation at different wavelengths. The light flux emitted by a first source is larger than that of the second source when a current is injected into each source, and the light flux of the second source is larger than that of the first source when a current of a different intensity is injected into each source.
