Product Features
DGS series explosive miner roadway lamp adopted LED light source as one kind green and environmental roadway lamp.it has advantages of smart 、 light weight、long life-span、non-pollution、maintenance-free、energy- saving and high security etc .
The roadway lamp adopted high lumen and power LED light source,which is high luminous efficiency,long life span and no need to change the light source within the life span .
The roadway lamp use the high voltage die- casting aluminum as frame ,surface powdered anti- static spraying ,also ,choose the rubber sealing element and tempered & transparent glass with excellent function high temperature resistance 、 aging resistance and integration design .
Main technology parameters：
Roadway lights Model Rated voltage V(AC) Rated power (W) Irradiation distance(m) Illumination(Lx) Maximum Dimensions(mm) Weight(kg)
DGS12/127L(A) 127 12 3 ≥10 217*147*190 1.6
DGS18/127L(A) 127 18 3 ≥10 217*147*190 1.6
DGS24/127L(A) 127 24 3 ≥10 716*217*147 2.4
DGS30/127L(A) 127 30 3 ≥10 716*217*147 2.4
Power supply voltage fluctuation range：when power supply voltage is fluctuant under the rated voltage between 75%~110% ,the roadway lamp should be lighten up.
Main uses and and scope of application
Miner explosive roadway Led is suitable for the roadway of underground the coal mine which has mixed explosive gas like methane 、 coal dust and indoor lighting application .it is not allowed to used as mine digging work .
Environment condition
Can be applied for below situations
a)Environment air pressure 86～110Kpa；
b)Environment temperature-20～+40°；
c)Air relative humidity isnt higher than 98%(+25°C)；
d)Underground coal mine having methane explosive mixture；
e)The environment with no obvious shaking and fierce vibration .
Product type
Explosive type ：Mining Explosive-proof
Explosive symbol ： ExdI.
Product operation standard
MT221-2005《Coal mine explosion-proof lamps and lanterns》and GB3836-2000《Electrical equipments used in the explosive gas environment 》。
Product construction
Mining explosive- proof Led roadway lamp is made up by three parts:light source (including LED light source ,reflector and electronic component plate etc ), explosive-proof frame (including die -casting aluminum , tempered &transparent glass frame ,rubber sealing element etc),protective cover .
Installing use and operation
Before installing ,pre-made hook for hanging the lamps ,must be solid and reliable.the distance between two lamps should be less than 30%,if the cable bending is too much ,then should add middle hook.
It must use three core antiflaming cable including ground wire.get off the hold- down nut at the two wire holes,disassemble the power cord clamp ,open the top cover ,handle with care,dont damage the explosive surface .put the hold- down nut 、 washer and sealing ring accordingly to the power cable ,then get the cable to the wiring cavity .
Getting the power zero line and firing line to copper screw (nonpolar requirement).connecting the ground wire to the relative cavity position,use the socket spanner and screwdriver twist to lock the hold-down nut and ground wire screw.the connecting should be very reliable .
After adjusting the cavity cable ,use the spanner to tighten the hold-down nut,be careful not to make the cable rotate itself.hold-down nut must compress the sealing ring tightly to avoid the water into the cavity ,or will cause the short circuit and damage the power source .after assemble the power cable plate,tighten the both ends screws.
Assemble the top cover carefully,to check the top cover water-proof sealing ring ,rotating the top cover slightly to the cavity ,align to the connecting hole ,and assemble the tighten bolt.if apply the cascading connect to assemble the lamps,it have to use wall plate at the power cable enter of lamp of the cascading end.
