As the patent No. be: 200520067583.6, denomination of invention is for kind of the Chinese utility model patent of the human body inductive lamp of band LED lamp, a kind of sense light is disclosed, by low-voltage circuit, sensing element, signal amplification circuit, comparator circuit, timer circuit, night on daytime control circuit and bulb form, it is characterized in that by day drawing in the control circuit at night and connect accepting under the state of human body sensing alive circuit and LED lamp for one tunnel night.The utility model has solved human body inductive lamp when do not work the night of dark, and people's eyes be can't see anything, and the life inconvenience that brings, as long as human body inductive lamp is in the human body sensing slave mode, the LED lamp just sends colored light.The shortcoming that exists is: 1, owing to there is not stand-by power supply, if during mains failure, sense light can not be lighted, and still can not normally use; 2, all use the LED lamp, considering to have certain brightness, LED wants a lot (40 or more), so in a single day, have a power failure, drag with battery, very power consumption, very short time, the point of battery just exhausted, can certainly strengthen the power of battery, but cost can rise significantly, market can't be accepted.
(3) summary of the invention
For overcome existing sense light do not have stand-by power supply, can not emergency service when the mains failure, deficiency that cost is high, even if a kind of emergent sense light of two-burner lamp that stand-by power supply also can normal power supply when mains failure, cost is low that provides is provided the utility model.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of pair of emergent sense light of light source, comprise LED lamp, human inductor, step-down finishing circuit, the city is electrically connected step-down rectifying circuit, described human inductor connects the LED lamp, described sense light also comprises common bulb, stand-by power supply and power supply switch circuit, and the output of described step-down rectifying circuit connects the mains supply end of power supply switch circuit; The output of described step-down rectifying circuit connects charging circuit simultaneously, and described charging circuit connects stand-by power supply, and described stand-by power supply connects the stand-by power supply end of power supply switch circuit; Described civil power connects common bulb by the K switch 3 that is subjected to human inductor control; Described stand-by power supply connects the LED lamp by the K switch 2 that is subjected to human induction switch control; Described power supply switch circuit comprises that being used to detect the power line dead electricity gets electric detecting unit, is used for according to connecting the stand-by power supply end after the detection power line dead electricity, get the control module that the mains supply end is connected in electric back, the output connection human inductor of described control module.
Further, described power supply switch circuit is a semiconductor control circuit.
Or: described power supply switch circuit is a relay circuit.
The beneficial effects of the utility model mainly show: even if 1, provide the stand-by power supply also can normal power supply when mains failure; 2, adopt during normal power supply common bulb, adopt the LED lamp when emergent, reduced cost; 3, adopted power supply switch circuit, intellectuality.
(4) description of drawings
Fig. 1 is the outside schematic diagram of sense light;
Fig. 2 is the circuit diagram of sense light.
(5) specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, Fig. 2, a kind of pair of emergent sense light of light source, comprise LED lamp 1, human inductor 2, step-down finishing circuit 3, the city is electrically connected step-down rectifying circuit 3, described human inductor 2 connects LED lamp 1, described sense light also comprises common bulb 7, stand-by power supply 4 and power supply switch circuit 6, and the output of described step-down rectifying circuit 3 connects the mains supply end of power supply switch circuit 6; The output of described step-down rectifying circuit 3 connects charging circuit 5 simultaneously, and described charging circuit 5 connects stand-by power supply 4, and described stand-by power supply 4 connects the stand-by power supply end of power supply switch circuit 6; Described civil power connects common bulb 7 by the K switch 3 that is subjected to human inductor control; Described stand-by power supply connects LED lamp 1 by the K switch 2 that is subjected to human induction switch control; Described power supply switch circuit 6 comprises that being used to detect the power line dead electricity gets electric detecting unit, is used for according to connecting the stand-by power supply end after the detection power line dead electricity, get the control module that the mains supply end is connected in electric back, the output connection human inductor 2 of described control module.
Described power supply switch circuit 5 is a semiconductor control circuit.Or: described power supply switch circuit 5 is a relay circuit.
In control module, adopt single-pole double throw formula K switch, can adopt semiconductor control device or relay to realize.Described stand-by power supply 4 is rechargeable battery or battery etc.Described human inductor 2 is the pyroelectric infrared-sensing switch, perhaps other inductive switches.
When the civil power normal power supply, power supply switch circuit 5 is failure to actuate, human inductor 1 operate as normal; When the civil power dead electricity, the test side of power supply switch circuit 5 detects the dead electricity signal, and the stand-by power supply end is connected in the control module saltus step, the stand-by power supply power supply, and when human inductor has detected man-hour, K switch 2 closures, the LED bulb is lighted; After the operation of city power recovery, the test side of power supply switch circuit 5 detects power on signal, and control module is saltus step once more, connect the mains supply end, recover mains-supplied, when human inductor has detected man-hour, relay coil is charged, drives K switch 3 closures, and common bulb is lighted.
