What should be paid attention to when installing LED ceiling lights?

1 Pay attention to two points during installation.

a. During the installation process, do not apply any pressure to the lead frame;

b. The place where it is installed on the circuit board, the spacing between the mounting holes on the circuit board.

2 Do not change the structure of the LED ceiling light.

During cleaning and maintenance, care should be taken not to change the structure of the LED ceiling lamp, and do not replace the components of the LED ceiling lamp casually.

3. Replace the LED ceiling light with a new one in time if there is a problem.

Replace the aging LED ceiling lamp in time according to the light source parameters provided by the sign to prevent unsafe phenomena such as ballast burning.

4 Look at the product manual of LED ceiling light.

After buying back LED lamps such as LED ceiling lamps, do not be busy installing them first, you should carefully look at the marks of LED lamps and read the installation and use instructions, and then install and use the lamps and lanterns according to the provisions of the manual, otherwise there may be danger.

5 Do not turn on and off LED ceiling lights frequently.

Try not to switch frequently when using LED ceiling lights, because the current through the filament is greater than the current when the LED ceiling lamp is frequently started, which makes the filament temperature rise sharply and accelerate the sublimation, which will greatly reduce the service life of the LED ceiling lamp, so it is necessary to minimize the number of switches of the LED ceiling lamp.

6 Precautions for cleaning LED ceiling lights.

It is forbidden to use unknown chemical liquids to clean LED lamps, which may damage the surface of LED resin and even cause resin cracks, if necessary, please immerse the LED in alcohol at room temperature for less than one minute.

7. There are three points to pay attention to in terms of safety.

a. Comply with public safety when using LED ceiling lights;

B. Direct visual vision of the LED ceiling lamp in the lit state will make the eyes uncomfortable and painful for a few seconds, so try not to look directly at the lit LED ceiling lamp;

c. It is forbidden to look directly when the ultraviolet LED ceiling lamp is lit.

Pay more attention.

When installing ceiling lamps in masonry structures, embedded bolts should be used, or fixed with expansion bolts, nylon plugs or plastic plugs; Do not use wooden wedges. And the bearing capacity of the above fixings should match the weight of the ceiling lamp. To ensure that the ceiling lamp is securely fixed, reliable and can extend its lifespan.

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 burial depth should be consistent with the bolt specifications.

The number of bolts 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; For lamps and lanterns without fixed mounting holes on the base (punch holes by themselves during installation), each lamp should have no less than 2 bolts or screws for fixing, 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 table is 75mm or less, it can be fixed with 1 bolt or screw.

Ceiling lamps can not be directly installed on combustible objects, some families use painted splints to line the back of ceiling lamps for the sake of beauty, 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 combustibles, heat insulation or heat dissipation measures should also be taken.

Before the installation of the ceiling lamp, it should also be checked: The cross-section of the wire core leading to each lamp, the copper core soft wire is not less than, and the copper core is not less than, otherwise the lead wire must be replaced. The connection between the wire and the lamp head, the connection of the parallel wire between the lamp head should be firm, and the electrical contact should be good, so as to avoid the danger of sparks between the wire and the terminal due to poor contact.

If the ceiling lamp is used in the screw lamp, the following two points should be paid attention to its wiring: the phase wire should be connected to the terminal of the center contact, and the neutral wire should be connected to the terminal of the thread; The insulated housing of the lamp head should not be damaged or leakage to prevent electric shock when replacing the bulb.

Ceiling lamps with incandescent bulbs, which should not fit snugly against the shade; The power of the bulb should also be selected according to the technical requirements of the product, not too much, so as to avoid the temperature of the bulb being too high, and the glass cover will splash down and hurt people after it is broken.

The electrical contact between the two wires connected with the power supply of the ceiling lamp should be good, and they should be wrapped in black tape respectively, and keep a certain distance, if possible, try not to put the two wires under the same piece of metal, so as to avoid short circuit and danger.

Teach children not to throw balloons and other objects indoors, so as not to hurt people or affect the decorative effect of lamps and lanterns.

Like a regular ceiling lamp, there's nothing special about it. The chassis is fixed, or one screw is in **, or three screws are fixed.

1.The electrical contact between the two terminals connected to the power supply of the ceiling lamp should be good, wrapped with vinyl cloth respectively, and kept at a certain distance. If possible, try not to put both terminals under the same metal sheet to avoid a short circuit and danger.

The phase wire should be connected to the terminal of the center contact, and the neutral wire should be connected to the screw terminal; When replacing the bulb, the insulated housing of the lampholder should not be damaged or leaking to prevent electric shock. When installing ceiling lamps in masonry structures, they should be secured with embedded bolts or with expansion bolts, nylon plugs or plastic plugs. Do not use wooden wedges.

And the bearing capacity of the above-mentioned fixings should match the weight of the ceiling lamp. This ensures that the ceiling lamp is fixed firmly and reliably, extending its service life.

2.When using expansion bolts for fixation, the bolt specifications should be selected according to the technical requirements of the product, and the drilling diameter and embedding depth should be consistent with the bolt specifications. Drill holes in the roof of the shed with the chassis.

Drill holes and lower the expanded rubber stopper. Thread the wires through the chassis and secure the chassis with screws. Wiring.

Install tubes and shades. After the lamp is installed, the power is turned on and the light test is turned on. Ceiling lamps cannot be mounted directly on combustible objects.

Some homes use painted plywood to decorate the back of ceiling lamps for added aesthetics. In fact, this is very dangerous, and it is necessary to do a good job of thermal insulation.

3.If the surface of the luminaire is flammable at high temperatures, thermal insulation or heat dissipation measures should also be taken. Ceiling lamps with incandescent bulbs, the bulb should not be near the lampshade; The power of the bulb should also be selected according to the technical requirements of the product, not too high, so as not to cause the temperature of the bulb to be too high, and the glass cover will fall down and hurt people after it is broken.

The electrical contact between the two terminals connected to the power supply of the ceiling lamp should be good, wrapped with vinyl cloth respectively, and kept at a certain distance. If possible, try not to put both terminals under the same metal sheet to avoid a short circuit and danger.

4.Ceiling lights are used very frequently. Therefore, when buying ceiling lamps, it is recommended to choose big brand merchants to cooperate and ask for invoices from merchants as much as possible.

If there is a problem, it can be repaired or replaced. Ceiling lights are used very frequently. Therefore, when buying ceiling lamps, it is recommended to choose big brand merchants to cooperate and ask for invoices from merchants as much as possible.

If there is a problem, it can be repaired or replaced. Special attention should be paid to the power cord of the ceiling lamp, the cross-sectional area of the wire must be greater than mm, because the lamp is live, and the fingers should not touch the metal lamp head during installation, so as to avoid the risk of electric shock.

When installing, you should determine the location of the installation, generally in the living room for installation, and you also need to close the electric switch, and then install the base reserved wire hole, you need to pay attention, can not be screwed very tightly, pay attention to cut off the power supply, pay attention not to destroy the lamp, and should also tighten the screws.

When installing, we must choose the right lamps, and then we should also pay attention to the selection of size and specifications, and at the same time, we should also pay attention to the location of the installation, and try to choose a professional decoration master for installation. When installing, pay attention to the connection between the live wire and the neutral wire, and try to choose the dark wire.

When installing, it can be installed on the ceiling in the room, and it is also necessary to pay attention to the connection of the line during installation, pay attention to close the electric switch in advance for installation, pay attention to the installation compactly, there can be no gaps, and pay attention to the overall color.
