Description

A kind of modular lighting dual-purpose flame-proof mine LED tunnel lamp of meeting an urgent need
Technical field
The utility model relates to technical field of lighting fixtures under the coal mine, is the emergent dual-purpose flame-proof mine LED tunnel lamp of a kind of modular lighting more specifically.
Background technology
Terrain environment is more special under the coal mine, the tunnel stringer of various functions is staggered, once something unexpected happened, the tunnel lamp loses mains supply, whole down-hole will be as dark as a stack of black cats, and will be totally unfavorable to withdrawing of operating personnel and rescue, therefore increase function of emergency illumination on the basis of tunnel lamp illumination, with convenient personnel escape in emergency circumstances, and provide ambient lighting for rescue.Shortcomings such as present tunnel lamp source mostly is fluorescent lamp or high-voltage gas discharging light, and power is bigger, and luminous efficiency is lower, has the emergency standby power heaviness that needs, and the crash time is short.The present band emergency function flame-proof mine tunnel lamp that uses, power supply circuits and charge-discharge control circuit, emergency lighting circuit are one, in the use, can't satisfy the needs of user flexibility configuring product function, on producing, can't realize the modular combination of assembling, load module does not have versatility, has improved production cost yet.
Summary of the invention
In order to overcome above-mentioned shortcoming, the purpose of this utility model is the emergent dual-purpose flame-proof mine LED tunnel lamp of a kind of modular lighting of design.The technical scheme of this utility model is: charging circuit 6, constant-current source module 8 and voltage detecting circuit 1 are connected with the 127V power supply respectively, charging circuit 6 is connected with booster circuit 5 with battery pack 3, three-terminal voltage-stabilizing circuit 4, emergent commutation circuit 2 respectively, three-terminal voltage-stabilizing circuit 4 is connected with emergent commutation circuit 2, emergent commutation circuit 2 is connected with voltage detecting circuit 1, constant-current source module 8 is connected with LED lamp group 7, and booster circuit 5 is connected with LED lamp group 7.Its advantage is: the emergent dual-purpose flame-proof mine LED tunnel modulated structure of this modular lighting is reasonable in design, the novelty that is skillfully constructed, and it is not changing on the lamp project organization basis, original tunnel, increase the emergency lighting circuit, and realized it is characterized in that the modularization of function of emergency illumination, do not change former lamp project organization, the 127V mains supply just often, use the constant-current source module for power supply, when losing the 127V power supply, automatically switch to battery-powered, start function of emergency illumination, make light fixture continue to light.In addition, the utility model becomes an independently functional module with the emergency lighting circuit design, can add arbitrarily and remove and do not influence the technical parameter of former lamp, and the tunnel lamp and the shared same set of lamp body parts of common tunnel lamp of emergency lighting are arranged, improve efficiency of assembling, reduced user's use cost.Led light source light efficiency height, energy-conservation uses led light source significantly to improve the emergency lighting time.Adopt the high LED of luminous efficiency as lighting source, and constant-current supply and emergent independent separately, flexible Application is convenient in modularized design.
Description of drawings
Fig. 1 schematic block circuit diagram, Fig. 2 circuit diagram.In the accompanying drawing: 1, voltage detecting circuit, 2, emergent commutation circuit, 3, battery pack, 4, the three-terminal voltage-stabilizing circuit, 5, booster circuit, 6, charging circuit, 7, LED lamp group, 8, the constant-current source module.
The specific embodiment
Charging circuit 6, constant-current source module 8 and voltage detecting circuit 1 are connected with the 127V power supply respectively, charging circuit 6 is connected with booster circuit 5 with battery pack 3, three-terminal voltage-stabilizing circuit 4, emergent commutation circuit 2 respectively, three-terminal voltage-stabilizing circuit 4 is connected with emergent commutation circuit 2, emergent commutation circuit 2 is connected with voltage detecting circuit 1, constant-current source module 8 is connected with LED lamp group 7, and booster circuit 5 is connected with LED lamp group 7.When the AC127V AC-powered just often, the constant-current source module is converted into direct current with interchange, be 7 power supplies of LED lamp group, LED lamp group 7 is normally lighted, at this moment, D2 point voltage in the voltage detecting circuit 1 reaches 12V, drive relay K 2 closures in the emergent commutation circuit 2, Vout in the three-terminal voltage-stabilizing circuit 4 provides high level by the relay K 2 in the emergent commutation circuit 2 to the B of the Q1 utmost point, K3 in the emergent commutation circuit 2 disconnects, in the booster circuit 57 of J4,8 bipods lose 9.6V power supply, j3+ in the booster circuit 5 then, 2 of j3-do not have emergent output, and the U3 module in the charging circuit 6 is charged to rechargeable battery at this moment.When not having the AC127V power supply, D2 point voltage in the voltage detecting circuit 1 is 0V, relay K 2 in the emergent commutation circuit 2 disconnects, the K3 closure, battery pack 3 is by the J4 power supply of relay K 3 in booster circuit 5,7,8 pin of J4 obtain 9.6V voltage, and boost module is lighted led lamp group 7 by j3+, j3-among J4 output continuous current.As can be seen, the emergency lighting circuit is totally independent of the constant-current source module from accompanying drawing, and the interpolation of function of emergency illumination and removal do not influence the technical parameter of former lamp, have realized modularized design fully.
