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.
Larger space needs to be increased by other auxiliary light sources, and it is not suitable to use a single main light, then the wattage of main light can be reduced.The wattage of the light bulb may not be in line with the calculated value, but the actual selection results may vary by 15%Consider the selection principle of lamps and lanterns economically:1, large space should not use LED, LED lights now about 2.1 yuan /w, but the same illuminance, energy-saving fluorescent lamp less than half.2, frequent opening and closing of the lights, energy-saving lamps should not use, you can choose incandescent lamps, such as corridors3, the table lamp as far as possible (read) as far as possible not to use energy-saving fluorescent lamp, hurt eyes4, closed narrow lamps, as far as possible without LED lights, heat is not good, aging fast5, LED lights, try not to direct eyes, dazzling. Can be placed aloft, such as ceiling lamps, or in a lampshade.
Home improvement, if it is led lamps, then 1w/ square meters, that is, the living room 25 flat, choose 25w.But the bedroom can be a little smaller, hit a twenty percent off, or 15 flat, choose 12w.Similarly, the kitchen enlarged 1.1 times, the toilet 0.9 times, the study 2 times.If it is energy-saving fluorescent lamp, then you need to take 3 times.If it's an incandescent lamp, it will take 7.5 times.That is, led: energy-saving fluorescent lamp: incandescent lamp =1:3:7.5.The lamp light absorbing light shade effect, etc. Considering the effect, may need to take the numerical calculation of expansion coefficient of 1.1~1.5.
24 watts is enough, but also look at the lamp brand, but it is best to buy a big point, can not use so much to turn off part or change to warm colors
LED lights in the living room are generally around 20W, if there are other lights at the same time, or the number of lights a little bit more, you can consider 15W or so.
