If central air conditioning is not installed, the overall decoration effect of designers is generally 20-40. As a matter of fact, personally, it is not recommended to install a light trough. One is that the aesthetic degree has not increased much, and the other is that it has increased unnecessary costs. 12 cm is the minimum size and is not recommended. Even if I did, it wouldn't work. The size is too small, the lamp can't come out, the light is uneven, and the plaster line around the lamp trough is very ugly. Width: no more than 35 cm, height: 14 cm, depth of lamp groove: 5 cm, and vertical edge around reflector lamp groove: 5 cm. LED aluminum slot lamp embedded lighting; We often see linear light sources on Tik Tok network, as shown in the following figure. The size and width of linear lamps are usually 1cm to 5cm, and the height of lamps is usually 1cm to 3cm. The main function of the reflective lamp trough on the ceiling is to hide the light source and make it shine evenly. The size of the indoor ceiling reflective lamp trough is flexible, and the size of the lamp trough is determined according to the ceiling shape, ceiling height and light source in the reflective lamp trough.

I'm glad to answer this question. The ceiling lighting trough is generally 200 high and 400 wide. Specifically, the size can also be determined according to the size of the room and the golden ratio. Around the suspended ceiling, the suspended ceiling with reflective lamp trough generally comes down 13CM, and the maximum is not more than 15CM. The thickness of 7CM, that is, the slot size of the light strip = 13-7=6CM, which is relatively simple and generous. At present, the decoration is more about materials than decoration, that is, the decoration materials should be used well, but not gaudy. I suggest not to arrange reflective grooves indoors, because it is easier to hide ash.

According to the height of the indoor floor, the minimum size is generally 5 cm to 20 cm. The height of the hollow floor of the villa is more than four meters, and the living room can be between twenty and thirty centimeters, and the living room is between 280 and 400. If you are worried that the ratio is not good, you can ask the master to give you a line to the top on the spot, so that you can see whether the ratio is appropriate. Now most of the decoration is headlights (mostly several groups of lights are adjustable), downlights and light belts.
