Embodiment 1
As in figure 2 it is shown, the work process of the present embodiment has a following four situation:
1, opening (i.e. connecting the connection of external power grid and described power circuit 1, lower same) as on and off switch K1, when external power grid has AC to power, power circuit 1 powers to the second lamp group 22, and the second lamp group 22 is lighted.Power circuit 1 is charged the battery by the 3rd rectifier tube D3, the 4th rectifier tube D4 simultaneously.When battery underfill, over-charging of battery protection circuit 3 is not turned on, and the first lamp group 21 is in OFF state (grid of the 4th metal-oxide-semiconductor M4 of the detection on-off circuit 4 that now, has a power failure ends higher than its source voltage) because of voltage because of unpowered.When battery is charged to given voltage; voltage dividing bias circuit in over-charging of battery protection circuit 3 makes the reference electrode potential of the first controllable accurate source of stable pressure U1 and the second controllable accurate source of stable pressure U2 be increased to its conducting; now; transistor seconds Q2 turns on because there being bias voltage with the base stage of third transistor Q3; thus; the unwanted currents provided by power circuit 1 imports the first lamp group 21 by the 22nd resistance R22, the 23rd resistance R23, so that the first lamp group 21 is lighted.
2, opening as on and off switch K1, when external power grid is powered without AC, the second lamp group 22 unpowered does not works.Battery supply passes through the first current-limiting resistance R1, again by the first transistor Q1, the first metal-oxide-semiconductor M1 and the 4th metal-oxide-semiconductor M4 during other load (now the load of other in external power grid resistance is relatively low), " AC2 " end and the second resistance R2 unlatching power failure detection on-off circuit 4 in X1, on and off switch K1, " AC1 " end, external power grid, thus, after making the battery output current limliting by second current-limiting resistance R24, R25, power to the first lamp group 21 so that it is light.
3, (disconnecting the connection of external power grid and described power circuit 1, lower same) when on and off switch K1 is to close, first lamp group the 21, second lamp group 22 unpowered is extinguished.
4, when first lamp group the 21, second lamp group 22 is bright light, photoconductive 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, " 2nd " foot of control chip U5 is without output, " HD " end low level in Fig. 1, the 4th transistor Q4 cut-off in inductive switch circuit 6.The most described non-inductive signal of sensor circuit 5 exports.
When first lamp group the 21, second lamp resistance is for OFF state, the described photoconductive resistance R31 in Fig. 5 can't detect light, and " 2nd " foot of control chip U5 is without output.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 is sent, described control chip U5 " 2nd " foot then can export positive voltage and by R29 " HD " end output high level in Fig. 1, so that the 4th transistor Q4 in inductive switch circuit 6, first metal-oxide-semiconductor M1, 4th metal-oxide-semiconductor M4 conducting, now, battery passes through the second current-limiting resistance R24, R25 (the i.e. the 24th resistance and the parallel connection of the 25th resistance) powers to the first lamp group 21, first lamp group 21 is lighted.
Arriving when the time delay one preset in sensor circuit 5, the high level output of " 2 " foot of control chip U5 i.e. transfers to without output, and the first lamp group 21 is extinguished.
This control structure is especially suitable for people and gets up in the night to urinate night into use during lavatory.
The circuit of the present embodiment, uses isolation double-voltage electric power to power, and advantage is that charging rate is fast, isolates low-voltage circuit, and the safest, shortcoming is that power-efficient is relatively low.
Embodiment 2
In the present embodiment, the ground end after described first lamp group 21 is serially connected with the 3rd lamp group 23 between the current reflux end of power circuit 1.
As it is shown on figure 3, the work process of the present embodiment has following six kinds of situations:
1, in this situation; first lamp group 21 is lighted in the same manner as in Example 1 with extinguishing process; its difference is when the first lamp group 21 is lighted; 3rd lamp group 23 is also lighted, and in this structure, current loop is power circuit 1 current output terminal, over-charging of battery protection circuit the 3, first lamp group the 21, the 3rd lamp group 23 and power circuit 1 current reflux end.
2, in this situation, the first lamp group 21 is lighted in the same manner as in Example 1 with extinguishing process, this kind of situation, and the 3rd lamp group 23 is extinguished because of no current.
3, when on and off switch K1 is for closing, the first lamp group the 21, the 3rd lamp group 23 unpowered is extinguished.
4, this kind of situation is substantially the same manner as Example 1, and except for the difference that the illuminator 2 in this kind of situation is the first lamp group 21 and the 3rd lamp group 23.
It addition, the first lamp group 21 and the 3rd lamp group 23 be in OFF state and house, place nobody time, alarm signal can be sent by warning system to house owner people.When i.e. manager having thief to enter the room, as the infrared ray sensor KP1 in Fig. 6 collects the infrared induction signal of movement, control chip U6 " 2nd " foot output positive voltage, make the 5th metal-oxide-semiconductor M5 conducting via the 40th resistance R40 in " HT " end, Fig. 2, thus, warning circuit is connected.
5, open as on and off switch K1, when external power grid has AC to power, the outfan of power circuit 1 makes the 6th metal-oxide-semiconductor M6 turn on by the 41st resistance R41, the 6th diode D6, is powered for Baffle Box of Bluetooth circuit by " BLUE-" end, makes Baffle Box of Bluetooth work (as shown in Figure 7).
