Precautions for installing ceiling lamps
1. The two wire ends connected to the power supply line of the ceiling lamp should have good electrical contact and should be wrapped with black tape respectively and kept at a certain distance. If possible, try not to put the two wire ends under the same metal sheet to avoid short circuit and danger.
2. If the ceiling lamp uses a screw-type lamp holder, the following two points should be noted when wiring:
(1) The phase line should be connected to the terminal of the center contact, and the neutral line should be connected to the threaded terminal;
(2) The insulating shell of the lamp holder should not be damaged or leak electricity to prevent electric shock when replacing the bulb.
3. Rooms with high floors or vibrating ceilings are suitable for installing ceiling lamps. When installing ceiling lamps in masonry structures, embedded bolts should be used, or expansion bolts, nylon plugs or plastic plugs should be used for fixing; wooden wedges should not be used. And the load-bearing capacity of the above-mentioned fixings should match the weight of the ceiling lamp. To ensure that the ceiling lamp is fixed firmly and reliably, and to extend its service life.
4. When using expansion bolts for fixing, the bolt specifications should be selected according to the technical requirements of the product, and the drilling diameter and buried depth should be consistent with the bolt specifications.
5. Educate children not to throw balloons and other objects at lamps indoors to prevent the decorations hanging on the lamps from falling and injuring people or affecting the decorative effect of the lamps. When installing, special attention should be paid to the reliability of the connection between the lamp and the installation. The connection must be able to withstand a weight equivalent to 4 times the weight of the lamp without deformation.
6. The clearance height of the ceiling lamp is very small, and its effect is like a group attached to the ceiling. For spaces with low floor heights, thinner lamps can be selected; for spaces with high floor heights, cylindrical lamps with a certain height should be selected. For some rooms with larger areas, you can also choose a unified and varied ceiling lamp design and assembly, which will produce a new light environment artistic effect.
7. Ceiling lamps cannot be installed directly on flammable objects. Some families use painted plywood to line the back of the ceiling lamp for beauty. In fact, this is very dangerous and heat insulation measures must be taken; if the high-temperature part of the lamp surface is close to flammable objects, heat insulation or heat dissipation measures must also be taken.
8. Before installing the ceiling lamp, the following should also be checked: (1) The cross-section of the wire core of each lamp should not be less than 0.4mm2 for copper core soft wire and 0.5mm2 for copper core, otherwise the lead wire must be replaced. (2) The connection between the wire and the lamp holder and the connection between the parallel wires of the lamp holders should be firm and the electrical contact should be good to avoid sparks between the wire and the terminal due to poor contact, which may cause danger.
9. For 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 product technical requirements and should not be too large to avoid the bulb temperature being too high and the glass cover breaking and splashing down to injure people.
10. The number of bolts for fixing the lamp holder should not be less than the number of fixing holes on the lamp base, and the bolt diameter should match the hole diameter; for lamps without fixed mounting holes on the base (drill holes by yourself during installation), each lamp should be fixed with no less than 2 bolts or screws, and the center of gravity of the lamp should coincide with the center of gravity of the bolts or screws; only when the diameter of the insulating platform is 75mm or less, can one bolt or screw be used for fixing.
