How to calculate the lamp hole of aluminum gusset plate secondary ceiling

Usually, the distance between the farthest two lamps is measured, and then the number of lamps to be placed between the two lamps is calculated and added up. Finally, the quotient of the number of lights between two lights plus 1 divided by the distance between the farthest two lights is the distance between the two lights at the turn-on position. First, determine the frame size.

Under normal circumstances, walk around the side plate, and then the frame size. If not, you can report directly to the manufacturer of the production framework and ask them to help you calculate.

After confirming the position of the frame, punch corresponding holes in the position.

It is necessary to determine the size of the opening according to the size of the downlight, that is, through the aperture of the downlight. The normal range is about 7~ 10 cm.

In addition, it is necessary to combine the overall height of the downlight. If it is higher, the size of the opening will be larger and the depth of the ceiling will be greater.

Downlights are generally installed in the ceiling, and there are different sizes when the ceiling is opened, such as 2 inches, 3 inches, 4 inches, 5 inches and so on.

Generally speaking, it is enough to choose an opening size of 4 inches and a diameter of 10 cm.
