Lamp system with green-blue gas-discharge lamp and yellow-red led

摘要

The invention relates to a lamp system having—a gas-discharge lamp with a color point in the green-blue,—an LED with a color point in the yellow-red, and—an optical component for additive mixing of the light from the gas-discharge lamp and the LED, and to a corresponding method of illumination. A blue and green emitting fluorescent lamp is particularly suitable as gas-discharge lamp, and a red-yellow-emitting AlGaInP LED or a red-emitting AlGaAs LED as LED. Through additive mixing of the light from these high-efficiency light sources, the invention provides a highly efficient light source affording good color rendering, which contains all three primary colors and is particularly suited to the highly efficient generation of white light.
