How to connect the two ends of led lamp? Nowadays, led lights are the first choice in many families' daily life, but many people don't know how to install them. Here is an article about how to connect the two ends of led lights.

How to connect the two ends of led lamp? 1There are two wires at both ends of the LED lamp. When wiring, first distinguish the positive and negative poles of the lead, and then connect the positive lead with the positive terminal of the power adapter, and the negative lead with the negative terminal of the power adapter. When wiring, it should be noted that there are two charged zero lines at both ends of the LED fluorescent lamp, which are connected together. Don't connect all the live wires to one end.

What are the common types of lamps?

1, there are many kinds of lamps, including chandeliers, ceiling lamps, downlights and wall lamps. Among them, chandeliers and ceiling lamps are the most common indoor main lights. The chandelier is decorative and has a certain height. If you want to install chandeliers in the living room and other spaces, you should pay attention to whether the indoor floor height is low, so as to avoid the space looking depressed. When choosing chandeliers, we try to choose adjustable lamps.

2. Downlights are mostly installed on the ceiling as auxiliary light sources, and we can also design multiple downlights as substitutes for indoor main light sources as needed. Pay attention to the distance between the downlight and the wall when installing the downlight, because the downlight will heat up when working, and it will bake the wall yellow if it is too close to the wall. Indoor downlights should not be installed too much or too close. When installing the downlight, its mounting bracket should be stable and can bear the product weight of 10 times.

3. Wall lamps with various styles and soft light are often installed in balconies, corridors, bedrooms, living rooms and other places as supplementary light sources and decorative lights. For example, we install a wall lamp at the bedside, which is convenient for us to get up at night, read books and so on. Pay attention to the installation height of the wall lamp when installing it. Wall lamps are generally installed at a distance of 144 cm to 185 cm from the working face, and so on.

How to connect the two ends of led tube? If it is DC low voltage, the red line is positive and the black line is negative. If it is connected to the positive and negative poles, the LED light will light up. If it is double-ended, pay attention to the positive and negative poles, put the lamp in the lamp holder, and then turn the lamp. Power on to see if it can light up normally.

The two lines of LED lamp can be divided into two situations. One case is that one is the zero line and the other is the live line. There is no need to connect the lamp, just connect it directly to 220 volts. If the wire comes from the inside of the power supply, it should be connected to the circuit board of the lamp, but pay attention to distinguish the positive and negative poles, otherwise the wrong connection will lead to the burning of the lamp bead.

Matters needing attention in the use of led tubes

1, the LED tube is extremely close to the top of heaters such as electric, gas and kerosene stoves, or directly meets steam. Ordinary lamps should not be used to prevent high temperature from damaging lamps and bringing harm to people.

2. Lamps and lanterns must be used at predetermined voltage and frequency. All grounding lamps and lanterns must always check the wiring and grounding conditions to prevent the danger caused by leakage.

3. Indoor lamps cannot be moved to outdoor use, because the requirements of indoor and outdoor lamps are different, and indoor lamps do not have the ability to resist the sun and rain.

How to connect the two ends of led tubes 3 ED fluorescent tube wiring can be divided into three types, namely double-ended wiring, single-ended wiring and staggered wiring.

The upconverter and ballast in traditional fluorescent lamps are not used in LED fluorescent tubes, and the inductive ballast will consume some power. According to the actual measurement, the input power of 18WLED fluorescent lamp can reach 20 and 5W without removing the inductive ballast, which wastes 2 and 5W.

Suggestion: 1. The upconverter must be removed. 2. If it is really inconvenient, you can remove the inductive ballast.

Under the above three connection modes, led fluorescent tubes can work normally with or without inductive ballast.

Double-ended connection is a common connection method in the early days, because it is convenient to connect and simple to age. So far, many LED lamp manufacturers have adopted it. Shorten the two pins of the lamp holder, and then connect it to the internal constant current power supply. This connection mode can work normally only by removing the traditional upconverter.

Single-ended wiring method: one end of the led tube is not connected, and the two pins at the other end are respectively led to a constant current driving power supply. There is no connection between the two lampholders. The biggest advantage of this is safety. If one end of the led tube is electrified with alternating current, the other end will never be charged. When replacing the traditional fluorescent lamp, it is necessary to remove the original upconverter, replace the upconverter fuse and install the lamp tube.

Staggered wiring is a relatively new wiring method. This line pair

There are some requirements for the internal drive of LED tubes, which require two AC input terminals. The biggest advantage of this connection mode is that it can work normally with or without an infinite frequency converter. Only the lamp tube needs to be replaced when replacing, and the operation is very convenient. This connection is compatible with electronic ballasts such as Philips, OSRAM, Hitachi, Panasonic and Toshiba.
