Embodiments of color temperature modulation

An embodiment of the color temperature regulation of the color temperature tunable LED luminaire shown in fig. 1-6 is described below with reference to fig. 7-8. Fig. 7 is a schematic diagram of adjusting the color temperature of the LED light using the color temperature adjusting key of the present machine shown in fig. 1-6 according to an embodiment of the present invention. FIG. 8 is a schematic circuit diagram of the embodiment shown in FIG. 7 for adjusting the color temperature of the LED light by using the color temperature adjusting key of the LED lamp local machine.

As shown in fig. 7-8, the trigger signal is provided to the microcontroller unit MCU of the LED luminaire by pressing the color temperature adjustment key 30 once (i.e., once to turn on/off the circuit). The memory of the MCU can be used for setting (burning) the matching combinations of the working currents of the LEDs with different color temperatures (for example, x% I in the case of mixing two lights with different color temperatures) ₀ +y％I ₀ In which I ₁ Operating current of LED light of a first color temperature, I ₂ The values of x and y for the operating current of the LED light of the second color temperature can be arbitrarily set as required, as long as x + y =100 is ensured).
