Embodiment
With reference to the accompanying drawings, will be described in detail embodiment of the present utility model.
Fig. 1 is the overall structure figure of the explosion-proof identification light of the utility model.This explosion-proof identification light comprises housing 6, is adhesive in the luminous element of housing 6 front surfaces, the power supply circuits 7 in the housing 6, luminous element comprises the armorplate glass 9 that is arranged in order from front to back, mark plate 10, by luminous plaque 3, insulating blanket 11 that light-emitting diode is formed, also be provided with the electric wire 8 that connects power supply circuits 7 and luminous plaque 3.
Fig. 2 is the circuit block diagram of the explosion-proof identification light of the utility model.Power supply circuits 7 comprise the commutation circuit 2 that is connected with luminous plaque 3, the power circuit 1 that is connected with commutation circuit 2 respectively and charged lithium cells 4, wherein also be provided with the charging control circuit 5 that is used to connect power circuit 1 and charged lithium cells 4, charging control circuit 5 adopts the linear lithium cell charging chip of high accuracy.
Fig. 3 is the circuit diagram of the explosion-proof identification light of the utility model.The commutation circuit 2 of the explosion-proof identification light circuit of the utility model adopts electromagnetic relay, and charging control circuit 5 comprises linear lithium cell charging chip of high accuracy and switch block.In order to make the brightness of illumination height, described light-emitting diode has adopted high brightness LED.
Specify the course of work of the explosion-proof identification light circuit of the utility model below according to Fig. 3.
At first, behind external ac power source (220V/50Hz) process transformer TC, rectifier bridge VD, filter capacitor C1, the voltage stabilizing circuit (three-terminal voltage-stabilizing integrated chip L7806CF), export stable 6V direct voltage.
Then, this 6V direct voltage is used to switch electricity work and charging work.
Switch operating is mainly finished by electromagnetic relay HHC66A (T73), the coil of electromagnetic relay is connected on the 6V direct voltage of external power source output, its contact is the single-pole double throw formula, a pair of normally opened contact and a pair of normally-closed contact are arranged, the shared common point in these two pairs of contacts, common point is connected on the luminous plaque positive pole by diode D4.Behind 6V direct voltage serial connection two diode D2, D3 that external power source generates, be connected to the Chang Kaiduan contact of electromagnetic relay, the positive pole of battery BAT is connected to the normal-closed end contact of electromagnetic relay.Under this connected mode, when the outside has power supply to supply with, the coil electricity adhesive of electromagnetic relay, the normally opened contact closure, normally-closed contact disconnects, and luminous plaque circuit and external power source loop are connected, and luminous plaque is directly by the external circuit supply power.When external power source cuts off, the coil blackout of electromagnetic relay, the contact resets, and the luminous plaque circuit excises from external power source, then connects with charged lithium cells BAT loop, and luminous plaque voltage is provided by charged lithium cells.Simultaneously, two diode D2, D3 of above-mentioned serial connection have also played reverse blocking function, prevent that charged lithium cells is to the external circuit back discharge.
Charging process is: when external power source, the 6V direct voltage is powered to luminous plaque through two diode D2, D3, simultaneously, and behind the 6V direct voltage process diode D1, for charged lithium cells provides stable voltage.Charging chip adopts the linear lithium cell charging chip of high accuracy VA7205CF.When charged lithium cells was charged, this charging chip was monitored the voltage of charged lithium cells at any time, when the voltage of charged lithium cells approaches to saturation, promptly transferred constant voltage charge (trickle charge mode) to by constant current charge; Behind the voltage saturation of charged lithium cells, Q1 stops charging process by switch block.When the voltage of charged lithium cells drops to certain value, start again by switch block Q1 charging process.So circulation makes charged lithium cells be in the full state of electric weight all the time, is the emergent electric energy that provides sufficient that uses at any time.
In addition, owing to adopted adhesive means between the housing of this explosion-proof identification light and the luminous element, and luminous element and power supply circuits separate fully, so be applicable to IIA, IIB, the IIC class explosive gas atmosphere of 1 district, hazardous area, 2 district, the Applicable temperature group is T1-T6.
