Abstract:
A method of a light color temperature switching control for an LED lamp includes using a first LED lighting load emitting a low color temperature light and a second LED lighting load emitting a high color temperature light, using a light diffuser covering the first LED lighting load and the second LED lighting load to create an effect of a mingled color temperature for the LED lamp, using a power switching circuitry to execute a power allocation algorithm to manage electric powers respectively delivered to the first LED lighting load and the second LED lighting load while keeping a total electric power delivered unchanged to control a diffused light with desired color temperatures. A light intensity of the LED lamp is also adjustable by keeping a ratio of electric power allocation between the first LED lighting load and the second LED lighting load without shifting the mingled color temperature.

Claim (Index 1):
A method of performing a light color temperature switching control mode for an LED lighting device, comprising:\n using at least two LED lighting loads emitting lights with different color temperatures including at least a first LED lighting load emitting a light with a low color temperature and a second LED lighting load emitting the light with a high color temperature to form a light emitting unit; using a light diffuser to cover the at least two LED lighting loads emitting lights with different color temperatures to create a diffused light with a mingled color temperature; using a power switching circuitry installed between a power source and the at least two LED lighting loads including at least the first LED lighting load and the second LED lighting load for controlling an electric power delivered from the power source to the light emitting unit; using a power allocation algorithm to execute a reverse yet complementary power adjustment process for managing a first electric power X delivered to the first LED lighting load and a second electric power Y delivered to the second LED light such that a total electric power T delivered to the light emitting unit remains unchanged while the mingled color temperature of an illumination of the light emitting unit thru the light diffuser can be adjusted according to the following color temperature tuning formula;\n CT app =CT 1 \u00b7X /( X+Y )+ CT 2 \u00b7Y /( X+Y ), \n wherein CT app  is the mingled color temperature of the light emitting unit thru the light diffuser, CT 1  is the low color temperature of the first LED lighting load and CT 2  is the high color temperature of the second LED lighting, where the sum (X+Y) represents the total electric power T delivered to the light emitting unit; wherein X/(X+Y) represents a ratio of the total electric power allocated to the first LED lighting load and Y/(X+Y) represents a remaining ratio of the total electric power allocated to the second LED lighting load;\n using an external control unit comprising at least a first external control device to activate the power allocation algorithm for selecting a desired mingled color temperature.
