Method for emitting filament lamp-like light by LED lamp, involves controlling LEDs with different color temperatures independent of each other such that temperatures and mixed light outputs of LEDs are considered during dimming of lamp

摘要

The method involves mixing light outputs of two LEDs (4, 5) with different color temperatures, where one of the LEDs emits light of low color temperature and the other LED emits light of high color temperature. The LEDs are controlled independent of each other such that the color temperatures and the mixed light outputs of the LEDs are considered during dimming of a LED lamp. Operating current of the LEDs is controlled by a controller (7) during dimming of the LED lamp, and radiation power of the LED lamp is adjusted by an input device (6).
