Lamp installation requirements and methods

(I) Installation requirements

1. Lamps and fittings should be complete. There should be no defects such as mechanical damage, deformation, paint peeling, and lampshade cracking.

2. The bearing capacity of the fixture on the wall ceiling of the installed lamp should match the weight of the fixture.

3, hanging lamp should be equipped with a hanging box, each hanging box can only hold a set of chandelier. The surface of the pendant lamp must be well insulated and no joints are allowed. The conductor cross-section must not be less than 0.4 square millimetres. The wiring in the terminal box should take measures to prevent the lamp head from being forced to drop the lamp. Lamps with a weight of more than 1 kilogram should be equipped with a hanging chain. When the weight of a chandelier lamp exceeds 3 kilograms, it should be fixed by a pre-embedded hook or bolt. The light of the hanging chain light should not be pulled, and the light line should be forked together with the hanging chain.

4. The ceiling lamp with incandescent lamp as light source shall not be directly installed on the combustible component; the lamp shall not be close to the lamp cover; when the distance between the lamp and insulation table is less than 5 mm, heat insulation measures shall be taken between the lamp and the insulation table. . The power of the incandescent lamp must not exceed the maximum power allowed by the luminaire.

5, when the fluorescent light source, the ballast should be installed on the phase line, in the lamp should be to prevent the lamp foot off the shell, and in the lamp box should have a margin, giant lamp frame and the ceiling of the decorative line parallel, lamps The frame should be close to the ceiling.

6. The screw base phase should be connected to the terminal on the center contact. The neutral wire should be connected to the screw terminal. The insulating cover of the lamp base should be complete, without damage and leakage.

7. The hook of the fixed lantern should not be smaller than the lamp hook, and the minimum diameter of the lamp should not be less than 6mm.

(two) installation methods of several lamps

Chandeliers: When the chandelier is installed on the concrete top surface, it can be fastened with embedded parts, penetration bolts and expansion bolts. The size and the weight of the visual luminaire when installing determine the specifications of the expansion bolt used, but the minimum should not be less than M6 (mm), the multi-head chandelier should not be less than M8 (mm), and the number of bolts should be at least two. Light self-tapping expansion tube screws cannot be used.

Ceiling light: ceiling lights have a round, square or rectangular base (chassis), base sizes vary. The base of the lamp can be fastened with expansion bolts, or it can be fastened with wood screws on the embedded bricks. If the lamp base diameter exceeds 100 mm, 2 screws must be used. Lamp base installation If using embedded bolts, penetration bolts, the bolt diameter must not be less than 6 mm. Fixtures can be fixed on the platform using wood screws. The number of wood screws should not be less than the number of mounting holes given by the fixture.

Wall lamp: The wall lamp can be used with or without a base station depending on the structure of the base. When using the platform, fix the platform first and then fix the wall light on the platform. The base station is usually made of wooden boards, the thickness of the board should be greater than 15 mm, and the surface should be painted with decorative paint. When the wall light is installed, it can be fixed by screwing in the mounting screw hole of the lamp position box, or it can be fixed on the wall surface by punching, pre-embedded wood bricks or using plastic expansion tube screws. Wall lamp base screws are generally not less than 2. The installation height of the wall lamp is generally 2~2.2 meters from the center of the lamp, and the wall lamp installed on the bedside is preferably 1.2~1.4 meters.

Downlights: Downlights are recessed luminaires suitable for ceilings. The basic form of the lamp is cylindrical, and the lamp mouth is a lead-plated, titanium-plated or nickel-plated metal wide-brimmed ring. After the lamp is installed, it closely adheres to the top surface and has a good decorative effect. Symmetrical sides of the lamp body have a snap spring as a device for fixing the lamp. The opening is in the direction of the lamp and the butterfly nut is used to adjust the spacing of the circlip. installation steps:

a. Drill the hole on the ceiling according to the size of the downlight and the installation position.

b. Connect the reserved power cord in the ceiling with the downlight.

c. Adjust the wing nut fixing the spring nut to make the height of the spring sheet the same as the ceiling thickness.

d. Push the downlight into the ceiling opening and install a suitable bulb.
