Abstract:
A technology for configuring a lifestyle LED light with a tunable light color temperature is disclosed. The technology of tuning the light color temperature is made possible by blending two LED loads emitting light with different color temperatures thru a light diffuser with an arrangement that a first electric power delivered to a first LED load emitting light with a low color temperature and a second electric power delivered to a second LED load emitting light with a high color temperature are reversely and complementarily adjusted for tuning a diffused light color temperature such that a total light intensity generated by the LED light is kept essentially unchanged.
