Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a control circuit of two colour temperatures of single channel, including the power of adjusting luminance 1, light modulator 2, first light emitting component 3, second light emitting component 4 and resistance 5, 1 positive terminal electric connection in the power live wire of power of adjusting luminance, 1 negative pole end electric connection in the power zero line of power of adjusting luminance, 1 control terminal electric connection in light modulator 2 of power of adjusting luminance, 1 input of power of adjusting luminance connects in parallel in first

light emitting component

3 and 4 input of second light emitting component through the wire, first

light emitting component

3 and 4 output of second light emitting component pass through wire electric connection in 1 input of power of adjusting luminance, first light emitting component 3 is established ties by multiunit lamp pearl and forms, second light emitting component 4 is established ties by lamp pearl and a set of resistance R and forms.

The number of the groups of lamp beads in the second light-emitting component 4 is more than one group less than that of the groups of lamp beads in the first light-emitting component 3, and the dimming power supply 1 is one of silicon controlled rectifier dimming, Pwm dimming, resistance dimming, 0-10v dimming and DALI dimming. The dimmer 2 is of the DV-600P type. The resistor R is an adjustable resistor, wherein the resistor is a numerical value obtained by calculating the lamp bead VF.

One specific application of this embodiment is: the lamp beads in the first light-emitting component 3 can be 6000 k; the final lamp bead of the second light-emitting component 4 is a 2000k lamp bead; wherein, 12 lamp beads of 6000k are connected in series, the normal voltage of each lamp bead is 3v at 60ma, and the total voltage of the 12 lamp beads is 36 v; the 2000k lamp beads are 11 series connected with a 50 ohm resistor 5 in series, when the current is 60ma, the resistance voltage difference is 3v, the 11 lamp beads are connected in series with 33v, and the 11 lamp beads and the resistor 5 are connected in series with the voltage of 36v when the current is 60 ma; therefore, when the lamp beads are operated at 100% of power, the lamp beads at 2000k and 6000k emit light by 100%, and the emitted mixed color temperature is about 4000 k. When the total current is small, for example 6ma, assuming that all the current flows through the resistor 5 and the voltage is 0.3v, the current becomes smaller and smaller, the current is large when passing through the lamp bead (2000k) in the second light emitting component 4, and finally, the current completely passes through the lamp bead string of the second light emitting component 4, and the lamp bead string of the first lamp bead basically does not emit light because the voltage difference is lower than that of the lamp bead. The on-current of the first color temperature can be adjusted by adjusting the size of the series resistor 5, for example, 20% of the brightness of the first color temperature starts to be on; further, from the habit of people to use, low brightness requires a warm color temperature, and high brightness requires a cool white color temperature; the second light emitting component is preferably a warm white color temperature of 2000 k.
