Title:
Regulation of the color temperature in the LED lighting system whose light can be modulated
Document Type and Number:
Japanese Patent JP6002699
Kind Code:
B2
Abstract:
A LED lighting system, such as a dimmable LED lamp, that may simulate the performance of an incandescent bulb. LED strings of different colors are connected to the output of a single LED driver that regulates an overall intensity of light produced by the LED lighting system. The color of the LED lighting system is controlled by circuitry, such as one or more switches, that allocates current between the LED strings to change the color temperature of light emitted by the LED lighting system as the light intensity changes.
