Description
Technical field
The present invention relates to a kind of lighting lamp more particularly to a kind of lamps and lanterns that may act as emergency lighting.
Background technique
Since LED light source has, brightness is high, low power consumption and other advantages, be increasingly used as various occasions illumination it
With.And light LED light source using battery and allow its persistently illuminate one section of longer time so as to during alternating current short interruption after
Continuous illumination is also desirable way.Although conventional emergency light has the function of that disconnect alternating current lights automatically, does not have
The function that power supply is also turned off manually can also be lighted and disconnect manually by powering on.
Market lamps and lanterns on sale are the functional requirements for not being able to satisfy following scene at present: using conventional for electrical connection side
Formula, in the case where there is alternating current supply, lamps and lanterns control light on and off by switch on wall;In the case where alternating current interrupts suddenly, lamps and lanterns are certainly
It is dynamic to light and be controlled by switch on wall its closing or light again.If the time that alternating current interrupts suddenly is to be in personnel activity
The frequent time, then lamps and lanterns light the fear that can reduce personnel automatically and collision is unexpected;If the time that alternating current interrupts suddenly
It is to be in the time of daytime or personnel activity infrequently, then after lamps and lanterns light automatically, people prefer to first close such lamp
Tool is just opened, and be as when alternating current does not interrupt right with retaining the electric power that lamps and lanterns are stored up when in need
Lamps and lanterns are opened on the switch on wall answered.
Then a kind of new lamp for being able to satisfy the above scene is needed.
Summary of the invention
The present invention provides a kind of safe emergency light, can be used as conventional lighting lamps and lanterns and is used, and can during commercial power interruption
It is realized and is closed by switch on wall.
The following technical solution is employed:
Safe emergency light, including main light source, main light source power supply circuit, key light source control circuit, chip power anode VCC are raw
At circuit, charging circuit, battery, hot terminal J9 and zero curve terminals J10;It particularly, further include programmable control chip
U2, power loss observation circuit and test circuit;The input terminal of the chip power anode VCC generative circuit is being connected to the battery just
The anode of pole and main light source power supply circuit;The output end of the chip power anode VCC generative circuit is chip power anode
VCC, chip power anode VCC power to the programmable control chip U2;The programmable control chip U2 includes for supervising
It surveys the first detection foot PTB5 of city's electricity condition, detect foot PTA3, for controlling main light source control for the second of input test feedback
The first output pin PTB6 that circuit processed opens and closes and the second output pin PTA2 for issuing test pulse;The first detection foot
PTB5 is connected with the output node of power loss observation circuit;The second detection foot PTA3 is connected with the output node for testing circuit;

It is supplied in normal situation in alternating current:
(1) when switch on wall is connected, alternating current in addition to feeding to main light source power supply circuit, also correspond to from hot terminal J9 and
Zero curve incoming end feeds to power loss observation circuit, and power loss observation circuit works due to must be electric at this time, then programmable control coremaking at this time
Piece U2 controls key light source control circuit by the first output pin PTB6 and enables, so that lamps and lanterns be enabled to light.
(2) when switch on wall disconnects, power loss observation circuit is because power loss is without working, and programmable control chip U2 exists at this time
It works under the action of battery electric power and learns power loss observation circuit power loss, in the case, programmable control chip U2 is logical
It crosses the second output pin PTA2 and issues specific pulse to test circuit, test circuit for the specific pulse and transfer to firewire wiring
J9 and zero curve terminals J10 is held, since switch on wall is to disconnect at this time, then the second detection foot PTA3 will receive continuous letter
Number, programmable control chip U2 can determine whether out it is artificially to turn off the light in the case, then passes through the first output pin PTB6 and controls
Key light source control circuit deactivates, so that lamps and lanterns be enabled to extinguish.
In the case where alternating current accidental interruption:
(1) when switch on wall is on, power loss observation circuit is because power loss is without working, programmable control coremaking at this time
Piece U2 works under the action of battery electric power and learns power loss observation circuit power loss, and programmable control chip U2 passes through second
Output pin PTA2 and issue specific pulse to test circuit, test circuit by the specific pulse transfer to hot terminal J9 and
Zero curve terminals J10 is to turn on due to switch on wall at this time, and pulse can be through switch on wall and hot terminal J9 and zero curve
Terminals J10 and be not turned off electrical appliances of switch on wall or power switch (because usually having it when accident power-off into other
His electrical appliance and firewire and zero curve is in an ON state), thus the second detection foot PTA3 can receive pulse signal, can compile at this time
Process control chip U2 can determine whether out it is accident power-off, then will control key light source control circuit by the first output pin PTB6 and open
With, even also lamps and lanterns light, realization emergency lighting.Hereafter, switch on wall is turned off manually in user, then referring to above to alternating current supply
The explanation of normal condition (2), the second detection foot PTA3 will receive continuous signal, and programmable control chip U2 can determine whether out it is people
To turn off the light, then passes through the first output pin PTB6 and control key light source control circuit and deactivate, so that lamps and lanterns be enabled to extinguish.
(2) when switch on wall is in closed state, referring to above to the explanation of alternating current supply normal condition (2), the second inspection
Continuous signal will be received by surveying foot PTA3, and programmable control chip U2 can determine whether out it is artificially to turn off the light, then pass through the first output
Foot PTB6 and control key light source control circuit deactivate, so that lamps and lanterns are still in OFF state.Hereafter, user opens wall manually
Switch, then referring to the explanation of alternating current accidental interruption situation (1), the second detection foot PTA3 can receive pulse signal, at this time above
Programmable control chip U2 can determine whether out it is accident power-off, and main light source control electricity will be then controlled by the first output pin PTB6
Road enables, even also lamps and lanterns light, realizes emergency lighting.
Safe emergency light of the invention, which has, can be used for conventional lighting, and when accident power-off can light automatically, but can pass through
The characteristics of switch on wall is closed, and the mode of connection is conventional, use easy to spread.
