1. When installing a ceiling lamp in a masonry structure, use pre-embedded bolts or fix it with expansion bolts, nylon plugs or plastic plugs. Wooden wedges are not allowed. In addition, the carrying capacity of the above-mentioned fixing parts should match the weight of the ceiling lamp to ensure that the ceiling lamp is fixed firmly and reliably, and its service life can be prolonged.
2. When using expansion bolts to fix, the bolt specifications should be selected according to the technical requirements of the product, and the drilling diameter and embedding depth must be consistent with the bolt specifications.
3. The number of bolts for fixing the lamp holder should not be less than the number of fixing holes on the base of the lamp, and the diameter of the bolts should match the hole diameter; lamps without fixed mounting holes on the base (punch holes during installation), each lamp is used for fixing The number of bolts or screws should not be less than two, and the center of gravity of the lamp must be consistent with the center of gravity of the bolts or screws; only when the diameter of the insulating table is 75mm or less, one bolt or screw can be used for fixing.
4. LED ceiling lights cannot be directly installed on combustible objects. Some families use painted three plywood to line the back of the ceiling lights for beautiful appearance. In fact, this is very dangerous and heat insulation measures must be taken; if the high temperature part of the surface of the lamp is close to When combustible materials, heat insulation or heat dissipation measures should also be taken.
5. Check before installing LED ceiling lamp:
①The cross-section of the wire core leading to each lamp, the copper core flexible wire is not less than 0.4mm², and the copper core is not less than 0.5mm², otherwise the lead must be replaced.
②The connection between the wire and the lamp cap, and the connection of the parallel wire between the lamp caps should be firm, and the electrical contact should be good, so as to avoid the occurrence of sparks between the wire and the terminal due to poor contact, which may cause danger.
6. Teach children not to throw balloons and other objects at the lamps indoors, so as to avoid the decorations hanging on the lamps falling and hurting people or affecting the decorative effect of the lamps.
