The result of psychological medisine shows that if one stay in darkness for a long time, he will become sullen. Regulation of the human endocrine will be effected. So it is good to health when you sleep with low light. Here is one electric health care night light. The internal wiring is shown as above. The capacitance reduce the 220V municipal electric power. After rectification of diode D1-D4, it supports diode D5-D9 lightening. The diode uses green light, because green light makes one feel calm and relax. The light of the electric health care night light is soft. It looks like the light of moon and make a warm atmosphere. It helps one become calm and fall asleep peacefully. The light uses semiconductor light emitting devices. The power is only 0.3 Watt. It saves power a lot and durable. (View)

Intergrated circuit CA3083 has 5 NPN transistor. They are used in the same P-type substrate. You can use it as PNPN thyristor switch. Their public substrate is used as anticathode. If any button closed switch connected with controlled silicon, the anticathode load relay will be pulled in and the alarm will send warning signal. If any sensing switch on portal or window is colsed by the thief, the corresponding light will be lighten and point out where the thief is. Before the computer resets by cut off the power supply, the warning will keep sounding. In normal times, the circuit does not cost any power. The controlled silicon can support power for the circuit.
