Radar energy-saving lamp is a human microwave sensing switch. When someone walked into the effective range, the lights turn on automatically, after a period delay of the automatic shut down. If the body in the range of activities, sustained light will lighten. Radar energy-saving lamps also have light control function, so that lights only at night. Figure is a radar-type energy-saving lamp circuit diagram. (View)

The figure as shown, 555 and R1、R2、C1 build up the astable multivibrator, the oscillation frequency is about 10KHZ, the duty cycle is nearly 50%. VT2、VT3 are used as the switch to amplify the current. When the oscillating square wave is high, VT2, VT3 will be conduction and then discharge to the LC; when the current is low, the energy storage of L supply power to the burden by the freewheeling diode circuit. When the condition is overvoltage, DW will breakdown and VT1 conduction saturated, C<0.7V, this process play the fuction of regulator and dynamic balance.

The pilot lamp which is installed in scene can helps the driver to determine the situation behind car. The phototransistor is used as optical signal sensor, when light shines on the photodiodor, relay J0 closes and one of the normal-open contact close too, if the green light open, it means that there is no obstacle behind car. If there are some obstacles block the light, relay J0 does not close, red light opens.

The darkroom exposure timer lamp circuit is as shown, the ne555 time base circuit and the potentiometer rp, capacitor c form the single-stable trigger. Usually the circuit is in reset state, pin-3 of ne555 send out the low-level current, relay K does not operate, exposure light E does not shine. LED led2 is designed as the indicator light, this indicator lightilluminates the dial of potentiometer rp. At this point the internal discharge of ne555 is conducted, capacitor C1 is shorted and can not be charged. k can be the small medium-power electromagnetic relay such as jzc-22f and dc12v.
