Specific embodiment is：A kind of indoor curtain lamp control circuit, it is characterised in that in LED power transformer (figure In be not drawn into) output end one singlechip controller is set, the singlechip controller can pass through three branch of programming Control The make-and-break time of six two level branch line access points of line circuit, i.e., by controlling the pulse current of two level branch line access point, control The brightness of LED, lighting time and light order.

Further, each branch line circuit is both provided with two two level branch lines, and six two level branch lines connect monolithic respectively Six interfaces of machine controller and ground connection, each two level branch line can individually form complete loop.

Further, described LED have LED11, LED21, LED31, LED41....LED1n, LED2n, LED3n and The multigroup lamps of LED4n, n represent the positive integer more than 1.

Further, the LED1n and LED2n it is adjacent series connection and it is positive and negative connect, LED3n and LED4n it is adjacent series connection and just It is anti-phase to connect.

Further, the LED1n and LED2n of the series connection are connected in parallel with the LED3n and LED4n to connect.

Further, the connection and singlechip controller of described LED1n, LED2n, LED3n and LED4n according to branch line circuit Complete complete loop.

The utility model also provides a kind of curtain lamp, using at the top of window indoors, between curtain and glass pane, curtain lamp Lamp employs above-mentioned control circuit.

Further, the curtain lamp can control the pulse current of six two level branch line circuit access points by single-chip microcomputer, And then control the brightness of LED, lighting time and light order.

The utility model and existing Technical comparing, have significant effect, essentially consist in：

(1) as a result of singlechip controller, triode and LED special arrangement, the LED1n and LED2n of series connection are just Anti-phase to connect, the LED3n and LED4n of series connection are positive and negative to connect, when pulse current along positive direction by when only have one of which LED It is bright, pulse current back through when, another group of LED is bright, so by the direction of the pulse current that controls each branch road and when Between, you can complete the lighting time to multigroup LED etc., light the control of order.

(2) by being set in three branch line circuits, transposition circuit and LED etc. are positive and negative to connect and triode the application Use, realize only with three branch line circuits to control the on and off of any combination of four groups of LEDs, with it is existing at least The design of four branch line circuits is compared to the use for saving wire, and wiring is simpler.

(3) control circuit is simple, and each individually two level branch line circuit can form single loop, and one of them is bad , other can be used alone, and be easy to later period maintenance and replacing.

(4) different lamp combinations are versatile and flexible, and using effect is good, can be widely applied to various occasions.

(5) it is low using LED power consumption, energy-conserving and environment-protective.

(4) illustrate：

Fig. 1 is the control circuit schematic diagram of indoor curtain lamp in the application.
