Cut wire core, then tin plate circle, rinse, smashed. According to its already device take soft plastic tube length of messenger wire broken, and the plastic pipe at both ends of the pipe head cut in half, the length of 20 mm, then the suspension wire wear into the plastic tube. Wear comfortable device set on the plastic tube. The crane lifted the lid and the lamp cover respectively set into the messenger wire at both ends, holding good insurance clasp, then cut into two and a half of soft plastic tube end close lap, heat bonding, then put the lamp line pressure on the hanging box and light mouth stud. Such as screws, find out the phase line and tag them, finally according to the plastic (wood) will disconnect the lamp installed machine installation joint method.
3.4.1.2 fluorescent lamp installation:
A suction, fluorescent lamp installation: according to the design to determine the location of the fluorescent lamp, fluorescent lamp against the building surface, fluorescent light box should completely cover the lamp box, on the position of the lamp box lay a hole into the line, to the power cord into the box and on into the line hole should be set plastic pipe to protect the wire. Looking for a good lamp box of the location of the screw hole, in light boxes on the floor of good hole with a drill, screw with machine screws and firm, should be used at the other end of the box tube expanding bolt to be fixed. If a fluorescent lamp is installed on the ceiling, should use the self tapping screws to fix light boxes on the keel. After light box fixed, the box to press the power supply cord into the terminal board (porcelain connector). The lamps and lanterns of reflector is fixed on the box, and adjust the box straight, finally the fluorescent tube is installed.
B chain hoist fluorescent lamp installation: according to the height of the installation of lamps and lanterns, the whole chain hoist good, hang chain hoist in light box hook, not all installed on the roof of the building plastic (wood), compiling fork will lead in that order within the chain hoist, and introduce light box, the box of into line hole should be set on a soft plastic tube to protect wire, pumped light boxes inside the terminal board (porcelain connector). Wire and the lamp socket box out of the power cord connection, with sticky plastic belt and black tape layered bind tightly. Straighten out joint buckle in the flange, flange should lift (box) center and the plastic on the center (wood), use wood screws to twist firmly. The reflectors of lamps and lanterns with machine screws on light boxes, adjust light feet, the last of tube installed.
3.4.1.3 various lanterns installation:
A combined type suction top lanterns installation: according to the embedded bolt and the position of the lamp box, use electric drill on the plate of lamps and lanterns good mounting holes and the outlet hole, when installation will plate in order to connect the power cord and from the lamps and lanterns of the wires and bind tightly. Should as far as possible put the wire into the socket box, and then put the plate mounting holes on the embedded bolt, make all round plate and ceiling tiejin, tighten it with the nut, and adjust the lamp, hanging lamps and lanterns of all kinds of ornaments, and for tubes and bulbs.
B hanging lanterns installation: will the lamps and lanterns and inserted the embedded good derrick, lamps and lanterns hanging pin is inserted after its tail to break into a swallow, and flatten it. Conductor is the good start, bandage sealed, straighten out after push up lamps and lanterns of upper buckle bowl, will joint such as the inside, and buckle bowl close to the ceiling, tighten the set screws. Adjust the light. Good light bulbs, and finally with chimney.
The installation of 3.4.1.4 band:
According to the envelop dimensions determine the bracket of lamps and lanterns of strong point, according to the specific weight of lamps and lanterns again carefully business accounting, made by stent material support, well after, according to the installation position of lamps and lanterns, tube expanding bolt embedded parts and the bracket fixed tightly. Light band of support can be directly fixed on the main keel; Big band must be under good embedded parts, the first light of stents with screws on the embedded parts, fixed bracket, use a light box machine screws on the scaffold, to introduce the power cord to a light box and the wire connection of lamps and lanterns and bind tightly. Adjust the light mouth and light foot, mount bulb or tube, superior lampshade, adjust the frame of lamps and lanterns should be parallel to the ceiling decoration line below. If symmetrical installation of lamps and lanterns, the vertical center axis should be in a straight line, deflection should not be greater than 5 mm.
The installation of 3.4.1.5 wall lamp:
First according to the shape of lamps and lanterns choosing appropriate wooden table (board) or lamps and lanterns of lamps and lanterns tap to put on it, allowance to symmetric around, and then use electric drill open good outlet hole in the plank and mounting holes, and also good installation holes on the bottom plate of lamps and lanterns, lamp holder of the lamps and lanterns line from wood (plate) thrown in the outlet hole, on the wall of the lamp box joint, and bind tightly, will be the joint into the box. The wood or wood for lamp holder box, with metope, available machine screws to wood directly fixed in the box on the ear, such as wood should be with tube expanding. Adjust the wood (plate) or tap of lamps and lanterns to make it a right not skew, reoccupy machine screws to screw in the wood of lamps and lanterns (board) or lamps and lanterns on the tap, finally with good light bulbs, lamp or chimney. Installed on the wall lamp, outdoor lamps and lanterns of the counter or tap and metope between should add waterproof rubber gasket, and should play good drainage hole.
