(1) When installing ceiling lamps in masonry structures, use embedded bolts or with expansion bolts, nylon plugs or plastic plugs. Do not use wooden wedges. And the carrying capacity of the fixing member should be matched with the weight of the ceiling lamp. To ensure that the ceiling light fixed, reliable, and extend its service life.
(2) When using expansion bolts, the bolt size should be selected according to the technical requirements of the product. The drilling diameter and the depth of embedding should be in accordance with the bolt size.
(3) the number of fixed lampholder bolts should not be less than the number of fixed holes on the base of the fixture, and the bolt diameter should be matched with the aperture; no fixed mounting holes on the base of the lamp (installation of self-drilling), each lamp for Fixed bolts or screws should not be less than 2, and the center of gravity of the lamp should be consistent with the center of gravity of the bolt or screw; only when the insulation table diameter of 75mm and below, can be used a bolt or screw fixation.
(4) ceiling lamps can not be directly installed in the combustible objects, and some families in order to beautiful paint with the three plywood lining behind the ceiling, in fact, this is very dangerous, must take insulation measures; if the lamp surface high temperature parts close Combustible materials, but also to take insulation or cooling measures.
(5) Ceiling light installation should also check: ① lead to each lamp wire core section, copper core cord is not less than 0.4mm2, copper core is not less than 0.5mm2, otherwise the lead must be replaced. ② wire and the lamp connection, the connection between the lamp connection between the wire should be strong, electrical contact should be good, so as to avoid contact with the wire and the terminal between the spark, and dangerous.
(6) If the ceiling lamp is used in the screw head, then the wiring should pay attention to the following two points: ① phase line should be connected to the center of the terminal, the zero line should be connected to the threaded terminal; Insulated housing should not be damaged and leakage, to prevent the lamp when the electric shock.
(7) installed with incandescent bulbs ceiling lamps, bulbs should not keep the shade; bulb power should also be selected according to product technical requirements, not too much to avoid the bulb temperature is too high, the glass rupture down after splashing The
(8) with the ceiling power supply line connected to the two threads, electrical contact should be good, but also with a black rubber cloth wrapped, and maintain a certain distance, if possible, as far as possible not to put the two threads on the same piece of metal , To avoid short circuit, dangerous.
(9) education children do not indoors in the room to throw balloons and other objects, so as not to hang the ornaments on the lights fall or affect the decorative effect of lighting.
