2, when mains switch K1 opens, when external power grid is powered without AC, the second lamp group 22 does not work without power supply.Battery supply is by the first current-limiting resistance R1, the first transistor Q1, the first metal-oxide-semiconductor M1 and the 4th metal-oxide-semiconductor M4 in power failure sense switch circuit 4 is opened again by other loads (other load resistance now in external power grid is lower) in X1, mains switch K1, " AC1 " end, external power grid, " AC2 " end and the second resistance R2, thus, after the current limliting that battery is exported by second current-limiting resistance R24, R25, power to the first lamp group 21, make it light.
3, (disconnect the connection of external power grid and described power circuit 1, lower same) when mains switch K1 is closedown, the first lamp group 21, second lamp group 22 is extinguished without power supply.
4, when the first lamp group 21, second lamp group 22 is bright light, photo resistance R31 (being arranged in the first lamp group 21 and/or the second house, lamp group 22 place) in sensor circuit 5 as shown in Figure 5 can detect light intensity, now, " 2 " the pin no-output of control chip U5, " HD " in Fig. 1 holds low level, and the 4th transistor Q4 in inductive switch circuit 6 ends.Namely the non-inductive signal of described sensor circuit 5 exports.
When the first lamp group 21, second lamp resistance is for OFF state, the described photo resistance R31 in Fig. 5 can't detect light, " 2 " the pin no-output of control chip U5.If now, first lamp group 21, when having people to move in the second house, lamp group 22 place, infrared sensor KP1 in Fig. 5 will sense the infrared ray that this person sends, described control chip U5 " 2 " pin then can export positive voltage and export high level by R29 to " HD " end in Fig. 1, thus make the 4th transistor Q4 in inductive switch circuit 6, first metal-oxide-semiconductor M1, 4th metal-oxide-semiconductor M4 conducting, now, battery is by the second current-limiting resistance R24, R25 (namely the 24 resistance and the 25 resistance is in parallel) powers to the first lamp group 21, first lamp group 21 is lighted.
Arrive when the time of delay one of presetting in sensor circuit 5, namely the high level output of " 2 " pin of control chip U5 transfers no-output to, and the first lamp group 21 is extinguished.
This control structure is especially applicable to people and gets up in the night to urinate night and to use into during lavatory.
The circuit of the present embodiment, uses isolation double-voltage electric power to power, and advantage is that charging rate is fast, and isolation low-voltage circuit, slightly safe, shortcoming is that power-efficient is lower.

2, in this situation, the first lamp group 21 is lighted with extinguishing process in the same manner as in Example 1, this kind of situation, and the 3rd lamp group 23 is extinguished because of no current.
3, when mains switch K1 is for closing, the first lamp group 21, the 3rd lamp group 23 are extinguished without power supply.
4, this kind of situation is substantially the same manner as Example 1, is the first lamp group 21 and the 3rd lamp group 23 unlike the lighting device 2 in this kind of situation.
In addition, the first lamp group 21 and the 3rd lamp group 23 be OFF state and in house, place nobody time, send alarm signal by warning system to house owner people.When namely having thief to enter the room in manager, as the infrared ray sensor KP1 in Fig. 6 collects the infrared induction signal of movement, control chip U6 " 2 " pin exports positive voltage, makes the 5th metal-oxide-semiconductor M5 conducting via the 40 resistance R40 in " HT " end, Fig. 2, thus, warning circuit is connected.
5, when mains switch K1 opens, when external power grid has AC to power, the output of power circuit 1 makes the 6th metal-oxide-semiconductor M6 conducting by the 41 resistance R41, the 6th diode D6, is Baffle Box of Bluetooth circuit supply, makes Baffle Box of Bluetooth work (as shown in Figure 7) by " BLUE-" end.
When mains switch K1 opens, when external power grid is powered without AC, battery supply makes the 6th metal-oxide-semiconductor M6 conducting by the 4th metal-oxide-semiconductor M4 of conducting, the first metal-oxide-semiconductor M1, the 39 resistance R39, the 7th diode D7, equally, held as Baffle Box of Bluetooth circuit supply by " BLUE-", make Baffle Box of Bluetooth work (as shown in Figure 7).
6, when mains switch K1 opens, when external power grid has AC to power, the output of power circuit 1 leads to remote control circuit remote control adjustment receiving circuit by the 5th diode D5, " YK+ " end and " BT+ " termination power supply, and user can be arranged information such as times by remote controller.
Under any circumstance, when sensor circuit in Fig. 6 senses that someone moves, just the inductive switch circuit in Fig. 2 is opened, then, the output of battery supply holds LED clock project circuit (as shown in Figure 8) by " BT+ ", LED50 projection lamp is bright, its light sent by information projection such as the times of liquid crystal display screen LCD1 on wall or floor.
Adopt non-isolated constant-current decompression power supply, series-fed, advantage is that power-efficient is higher, and shortcoming is series-fed current limited, and charging rate is slow.After adding projecting function, product has more novelty, and warning circuit shares the electricity of rechargeable battery simultaneously, and shares infrared sensor, as long as seldom cost just can be integrated, reduces the use of dry cell.
