Detailed analysis and simulation of how many W lamps are used in a large space

If the home has just been renovated, I am ready to buy LED lights, but do you know how many W LED lights are installed in the living room, bedroom, etc., to ensure that the light source is sufficient, is it bright?

Sufficient and bright, it is more convenient to evaluate after quantification.

The following is the illumination requirements of the hotel in the architectural lighting design standards can be used as a reference.

A brief introduction to some of the basic parameters of the luminaire, the following DIALux for a simple simulation:

The conditions are as follows:

Room: 3 x 4 meters, height 2.8 meters, wall reflection coefficient 50%, ceiling reflection coefficient 70%, floor reflection coefficient 70%, no sunlight, room

There is no window in the room, no furniture.

The room is mounted in the center of the ceiling with a single luminaire, with a luminous flux of 5000 lm and a beam angle of 120 degrees.

result

Floor illumination

In some cases, there will not be only one luminaire in the room, which is divided into ambient lighting and local lighting. In this case, the light is needed in the place where it is needed. The brightness of the insignificant place can be lower, and the utilization of light is higher. There is an sentiment, in which case the above basis is no longer applicable.

In this case, how many watts of light should be used? Guangmingyuan specially compiled a form for your reference.
