AN ILLUMINATION APPARATUS

摘要

The disclosure provides an illumination apparatus, particularly a desktop lamp, for forming a first lighting pattern of a first correlated color temperature on the surface, like cool white, a second lighting pattern of a second correlated color temperature on the surface, like warm white, the second lighting pattern being around the first lighting pattern, wherein the color temperature gradually changes from the first color temperature to the second color temperature in the portion of the surface between the first lighting pattern and the second lighting pattern. Additional light sources like light emitting diodes, an optical thin film attenuator with gradual transmittance of blue or a phosphor coating may be used.
