Ceiling lamp installation and use
As the heat of home decoration continues to heat up, the changes in ceiling lamps are changing with each passing day. They are no longer confined to the previous single lamps, diversified ceiling lamps, and diversified. They absorb the luxury and style of chandeliers and use ceilings. The installation method avoids the shortcomings of the large room that cannot be equipped with large luxury lighting. The lamp body of the ceiling lamp is mounted directly on the roof and is suitable for overall lighting, usually used in the living room and bedroom. The following points should be noted when installing and using the ceiling lamp:
(1) When installing ceiling lamps in masonry structures, use pre-embedded bolts, or use expansion bolts, nylon plugs or plastic plugs; do not use wooden wedges. And the bearing capacity of the above fixing member should match the weight of the ceiling lamp. To ensure that the ceiling lamp is fixed, reliable and can extend its service life.
(2) When fixing with expansion bolts, the bolt specifications should be selected according to the technical requirements of the product, and the drilling diameter and the buried depth should be consistent with the bolt specifications.
(3) The number of fixed lamp holder bolts should not be less than the number of fixing holes on the base of the lamp, and the bolt diameter should match the hole diameter; the lamp without fixed mounting holes on the base (self-punching during installation), each lamp is used for There should be no less than 2 bolts or screws, and the center of gravity of the lamp should match the center of gravity of the bolt or screw; only when the diameter of the insulation table is 75mm or less, it can be fixed by one bolt or screw.
(4) The ceiling lamp can not be directly installed on the flammable object. Some families use the three plywood after painting to lining the back of the ceiling lamp. In fact, this is very dangerous and must be insulated; if the surface of the lamp is near high temperature Insulation or heat dissipation measures should also be taken when combustible materials are used.
(5) Before installing the ceiling lamp, it should also be checked: 1 The section of the wire core leading to each lamp, the copper core cord is not less than 0.4mm2, and the copper core is not less than 0.5mm2, otherwise the lead must be replaced. 2 The connection between the wire and the lamp cap, the parallel wire connection between the lamp caps should be firm, and the electrical contact should be good, so as to avoid sparking between the wire and the terminal terminal due to poor contact, and danger occurs.
(6) If the screw cap is used in the ceiling lamp, the wiring should pay attention to the following two points: 1 phase wire should be connected to the terminal of the center contact, the neutral wire should be connected to the threaded terminal; 2 lamp cap The insulation case should not be damaged or leaked to prevent electric shock when replacing the lamp.
(7) Ceiling lamps equipped with incandescent bulbs, the bulb should not be close to the lampshade; the power of the bulb should also be selected according to the technical requirements of the product, not too large, to avoid the bulb temperature being too high, and the glass cover is broken and then splashed down. .
(8) The two wire ends connected to the ceiling of the ceiling lamp power supply should have good electrical contact. They should be wrapped with black rubber tape and kept at a certain distance. If possible, do not put the two wire ends under the same piece of metal. In order to avoid short circuit, danger occurs.
(9) Educate children not to throw balloons and other objects into the lamps indoors, so as to prevent the decorations hanging on the lamps from falling and injuring people or affecting the decorative effect of the lamps.
