Q:15 square meters of living with the Duodawa number LED ceiling lamps
General: the chandelier diameter of not more than 1/4 of the width of the living room (if your living room is 15 square meters, I estimate is 4 meters X4 meters, so your living room is 4 meters wide, so the lamp diameter of no more than one meter, maintained at about 800 mm in diameter and so on it) if the ceiling. The 400X800, select the appropriate square. If it's round, suggest 600. And the size of the power, then the living room of the LED lights are generally around 20W on it.
Q:Approach to LED ceiling lamp wiring method
Red and blue? Two red together, two blue together to form a pair of lines, and then separately in the 220V fire and zero, casually pick the root, regardless of color.
Q:LED ceiling light mounted in the living room, with subsection and remote control. The first paragraph (the first switch) all lights are blue (color change);
Check the switch first. Is there anything wrong with it?
Q:LED ceiling lamp, why is the light still dark after the power is switched off?. Is this power consumption?
No, there is silver light in the energy-saving lamp. After the light is turned off, the power has been cut off. Only the silver light is left behind. Don't worry about the electricity!
Q:What are the advantages and disadvantages of LED ceiling lamp?
High quality product price, quality assurance,,, but there are also more serious fever, heat environment, good, up to 20 thousand hours in the life is very difficult, do not believe in life. What business publicity 100 thousand hours also LED too strong point, is not conducive to a wide range. Household lighting; color; there is not too good, in particular, is not recommended for reading!
Q:Does the LED ceiling light sleep mode?
Hello, LED is to look at the ceiling type, if is dimmable LED ceiling lamps, can have a sleep mode, want to know more information about the LED dimming ceiling lamps, can use Baidu Search Fan Fuhua, to my blog, light adjustable LED ceiling lamp, the brightness is from 0 to the brightness, brightness will do what you want.
Q:LED annular patch ceiling lamp used less than half a year, a few days ago suddenly become very dark, what is the reason, how to solve?
Two possibilities. 1, the drive power fails, and its output current becomes low, resulting in distribution to the LED, current down, LED dimming. (this will be specific to see the driver power, for many reasons) proposed to change the whole light2, the original LED and drive power does not match. The maximum current output drive current is more than LED can bear, a long time, resulting in serious decay, dark (personally think that this is a great possibility that now drive the cost down, LED accounted for a lot of cost). It is recommended to change LED, the same number of strings, plus a few more (that is, increase the number of LED)Or please professional people with change, this is not bad, then, bad, basically the whole is better, and the main problem is matching.
Q:Led why does the ceiling lamp change brightness once a switch is applied?
Inside of your ceiling lamp, there is a sectional switch, and the ceiling lamp is divided into three groups. Each time, the brightness is increased by one group. Wish success.
Q:How does the LED ceiling lamp power supply match?
Change the lamp, the output 300V, accidentally, will give you a surprise, the old power estimation is bad, direct plus constant current driver or RC Buck Driver, do not use, is definitely fake products, if you have electrical maintenance capability, see the lamp string and the way to change. With a good supply, if there is no knowledge, forget it, or to spend money to buy, after all, LED is to use safety and environmental protection, get hurt yourself but not good.
