Ceiling lights are popular today for their beauty and soft light. Ceiling lights are installed directly on the roof, suitable for overall lighting, and are usually used in bedrooms, dining rooms, and parlors. The question many people have is: How do you install a ceiling light? What tools should be prepared? What issues should be noted in the installation process? Here we give you an introduction.
When installing ceiling lights in masonry structures, pre-built bolts should be used, or fixed with expansion bolts, nylon plugs or plastic plugs; wooden wedges should not be used. And the bearing capacity of the above fixings should match the weight of the ceiling lamp. To ensure that the ceiling lamp is fixed firmly and reliably, and can extend its service life.
When fixed with expansion bolts, the bolt specifications should be selected according to the technical requirements of the product, and its drilling diameter and buried depth should be consistent with the bolt specifications.
The number of fixed lampholder bolts should not be less than the number of fixed holes on the base of the lamp, and the bolt diameter should match the aperture; no fixed installation holes on the base of the lamp (installation of their own holes), each lamp should be used to fix the bolt or screw should not be less than 2, 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 and below, only 1 bolt or screw can be used Fixed.
Ceiling lights should not be installed directly on combustible objects, some families use painted plywood lined behind the ceiling lights for aesthetic purposes, which is actually very dangerous and must be insulated; if the high-temperature parts of the lamp surface are close to combustible objects, insulation or heat dissipation measures should also be taken.
Ceiling lights should also be checked before installation: the cross-section of the wire cores leading to each lamp, copper-core flexible wire not less than 0. 4 square millimeters, copper cores not less than 0. 5 square millimeters, otherwise the lead must be replaced. The connection between the wire and the lamp head, the connection of the parallel wire between the lamp head should be solid, and the electrical contact should be good, so as to avoid the danger of sparking between the wire and the terminal due to poor contact.
If the ceiling lamp is used in the screw head, the wiring should also pay attention to the following two points: 1) the phase wire should be connected to the terminal of the center contact, the zero wire should be connected to the terminal of the thread; 2) the insulation shell of the lamp head should not be broken and leakage to prevent electric shock when replacing the bulb.
The two wires connected to the power inlet of the ceiling lamp, electrical contact should be good, but also separately wrapped with black tape, and maintain a certain distance, if possible, try not to put the two wires under the same piece of metal, to avoid short circuit, a danger.
