Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Example (b):

as shown in fig. 1 and fig. 2, an aquarium lamp for dimming and color mixing by using potentiometers includes at least one group of aquarium lamps, and a plurality of potentiometers corresponding to the number of the group of aquarium lamps, the potentiometers are respectively disposed in a driving circuit of each group of aquarium lamps, the potentiometers divide a power voltage of the driving circuit, and a knob of the potentiometer is rotated to change a driving value of each group of aquarium lamps; in this embodiment, the aquarium light includes three groups of LED lights, and the light emitting colors corresponding to the three groups of LED lights are red, green, and blue, respectively.

Dimming power supplies can be simulated by three LED lamps, each controlling one color, e.g., red, green, blue. Different resistance values are generated by three independent rotary knobs of the potentiometer, different analog voltages are generated by voltage division, analog voltage signals are respectively transmitted to three adjustable light sources, each power source outputs different circuit values to drive corresponding LED lamps, the LED lamps emit light with different brightness under different currents, stepless dimming can be realized for three colors, and countless colors can be mixed.

In this embodiment, the driving circuit includes alternating current commercial power, rectifier bridge and constant current driver chip, alternating current commercial power through output direct current after the rectifier bridge rectification, direct current is through after the potentiometre partial pressure input constant current driver chip, constant current driver chip with the aquarium lamp is connected. As shown in fig. 2, the circuit principle of the specific driving circuit is that AC-L and AC-N are AC mains input terminals, AC is converted into dc through a fuse F1 and a rectifier bridge BD1, and the dc is filtered by a capacitor C1, a capacitor C2 and a capacitor C3, so that the voltage is stable, U1, U2 and U3 are constant current driving chips of the LED lamp, in this embodiment, 781mt 6 is selected, the three paths of operation principles are the same, and the principle of the constant current driving chip U1 is described by taking the path as an example: the direct current charges a constant current driving chip U1VCC through a resistor R1 and a resistor R2 to provide working voltage for the constant current driving chip U1VCC, a capacitor C7 is a decoupling capacitor to filter interference, a resistor R10 and a resistor R11 are current-limiting resistors to adjust the maximum value of output current, 2 pins of the constant current driving chip U1 are input ports of analog signals, the voltage range is 0-1.8V, when a knob of a potentiometer rotates, the voltage of the pin connected with a divided voltage can change from 0V to 1.8V, at the moment, the driving current can be proportional to the voltage to output current, and therefore the current of the circuit can be adjusted, and the brightness of each color can be adjusted. The working principle of the potentiometer knob group is as follows: the resistor R16 and the resistor R17 take electricity from the rectified capacitor, the voltage is stabilized through the voltage stabilizing tube ZD1, the voltage is 5V, then the voltage is divided through the resistor R18 and the potentiometer JP1, and the resistance value is changed when the knob is adjusted, so that the divided voltage is changed. The other two groups have the same principle.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
