LED light part i.e. energy-efficient/energy-saving lamp, has LED chips including color temperatures from color temperature spectrum of specific Kelvin combined with LED chips with low color temperature and LED chips with high red/blue parts

摘要

The light part i.e. energy-saving lamp, has multiple LED chips with different color temperatures from color temperature spectrum of 2160-3300 Kelvin combined with LED chips with low color temperature and LED chips with high red part and high blue part. LED chips with high color temperature are provided on a circuit board. Group of LED chips are arranged in rectangular form. The LED chips with the high color temperature are switched-off by canceling power. The LED chips with low color temperature are set under voltage, and reduce power during dimming process.
