A kind of emergency light, comprise drive circuit and light-emitting component, described drive circuit comprises ultracapacitor, gate-controlled switch and voltage stabilizing circuit, gate-controlled switch is connected between the input of ultracapacitor and voltage stabilizing circuit, the output of voltage stabilizing circuit links to each other with light-emitting component, and ultracapacitor is luminous by the voltage stabilizing circuit driven light-emitting element.
Described light-emitting component is a light emitting diode matrix.
Also comprise display circuit, this display circuit links to each other with described ultracapacitor, shows ultracapacitor institute carried charge by voltage sample.
Comprise also being used to detect the probe circuit that whether has a power failure that described probe circuit output control gate-controlled switch makes it when having a power failure or brightness connection gate-controlled switch when being lower than set point.
Also comprise charger, the output of charger connects ultracapacitor.
Described charger comprises constant-current circuit, and the output of this constant-current circuit links to each other with ultracapacitor, the input input DC signal of this constant-current circuit.
Described charger also comprises first diode, and the negative pole of described first diode links to each other with the input of constant-current circuit, the positive pole input DC signal of described first diode.
Described charger also comprises the AC/DC circuit and second diode, and the output of this AC/DC circuit links to each other with the positive pole of second diode, the input input AC signal of this AC/DC circuit.
Described charger also comprises charge switch, and this charge switch is controlled the ultracapacitor that outputs to of constant-current circuit.
Adopt the beneficial effect of above scheme:
(1) owing to adopt ultracapacitor as energy-storage travelling wave tube, with respect to rechargeable battery, the charging interval is short, can recharge, can shave once more fast again; The capacity of ultracapacitor is minimum with the capacity of the increase variation of charging times, and the life-span is long, discharges and recharges number of times greater than 100,000 times; Can realize 30-120 minute fluorescent lifetime by the capacity that changes ultracapacitor; The ultracapacitor internal resistance is little, and the charging loss is little, and energy savings especially is suitable for open-air no electrical network, has automobile or the hand generator just can quick charge.
(2) adopt light emitting diode matrix luminous, the life-span is longer than fluorescent lamp or incandescent lamp, and can regulate luminosity by the control light emitting diode matrix.
(3) probe circuit is set, in case receive power cut signal, and visit the signal that brightness need be thrown light on inadequately, need not manual control and just connect emergency light, greatly strengthened the practicality of emergency light.
(4) since ultracapacitor in use, its voltage is linear and descends, and therefore is connected to display circuit on ultracapacitor, shows ultracapacitor institute carried charge by voltage sample, whether can conveniently control needs emergency light is charged.
(5) after charging was finished, charger stopped charging automatically by the feedback turn off charge switch.
