Sihainet: in daily life, LED lamp is a very popular lamp. Many families choose to install LED lights for decoration. But many people don't know how many watts the LED light in the bedroom needs. Some people also find that the LED lights often flicker when they are off, so what's the matter with the LED lights off and flicker? May as well and small make up understand next!
How many watts does the LED light need in the bedroom
According to the current general bedroom area, LED lights generally choose 10 to 15 watts, the light in the bedroom is not too bright, so 10 watts is recommended.
What's the matter with the led off and flashing
The lights have been turned off, but the lights flash for a while. Although this flicker has no effect on the power consumption, the lights flash for a while in the dark night. You think it's a ghost movie!
The reason why the light flashes:
There are many reasons for the flicker of electric lights. Go to Baidu search, and the answer is that the zero line and the live line are connected reversely, that is, the switch controls the zero line. But this kind of situation often seldom occurs, the electric light switch controls the live wire, this is the electrician's most basic knowledge, the decoration electrician should not even understand this.
In addition, LED lamps are popular nowadays, but the internal resistance of LED lamps is small. If the electric light is in a narrow and circuit dense environment, such as balcony, it is easy to produce induced current, causing the electric light to flash.
Secondly, observe the flashing lights. If there are multiple lights flashing in the room, and these lights belong to the same circuit, consider the reverse connection of the zero line and the live line in the distribution box. If it is confirmed that the zero line and the live line in the distribution box are connected reversely, the two lines at the lower opening of the circuit breaker need to be exchanged. After the exchange, make sure to mark. The line colors of the zero line and the live line in this circuit are exchanged to avoid any impact on future maintenance.
Switch control zero line, in addition to flashing lights, may also produce electric shock hazard. If this problem is found, it must be changed in time, do not be afraid of trouble.
If it is confirmed that the zero line and the live line are not connected reversely, it is possible that the electric lamp generates self induced current. This situation has a feature, that is, the flashing frequency of LED is relatively high, the flashing frequency of fluorescent lamp is relatively low, or it may not flash after replacing the fluorescent lamp. In this case, there are two ways. One is to replace the incandescent lamp. Since the incandescent lamp has no rectifier, it will not generate self induced current. The disadvantages are low brightness, low life and power consumption.
Or buy a 220 V relay, and connect the relay coil in series to the circuit to absorb the induced current.
Advantages of LED bulb
1. LED bulb has a long service life. Generally speaking, compared with other general lamps, LED bulbs have a very long service life, which can reach more than 50000 hours.
2. LED bulb can adapt to a variety of state environment, general energy-saving lamp is very easy to break if it is in the state of frequent opening and closing, and led bulb can adapt to this high state of the working environment.
3. The production of LED bulb integrates the world's top light distribution technology. Its light source is a surface light source, which can increase the luminous surface and is very friendly to people's eyes.
4. There are no harmful substances such as mercury and lead in the LED bulb, so it has no pollution to the environment.
Disadvantages of LED bulb
1. Although the light attenuation of LED lamp is low, it is basically for high-power LED lamp, while the light attenuation of low-power LED lamp is still relatively large.
2. The light color of LED lamp is white light. Due to some defects in manufacturing process and the matching error of lens, it is easy to form a yellow circle when using, which will affect the lighting effect.
