Lighting is quite important for living space, so determining the number of lighting lights needed requires careful consideration based on many factors such as room area, purpose of use and interior architectural characteristics.
Housewives can refer to the following 4 things to help calculate the number of lights in the house appropriately, bringing high efficiency when using.
Determining standard lux
The lux is an index measuring the amount of light per unit of area. Each functional space in the house has different level of brightness requirements to ensure efficiency when used. Normally, the living room space will need 150-300 lux, the bedroom from 150 lux while the kitchen and bathroom space will need higher radiation of about 400 - 800 lux.
Determining the correct standard lux lux lux luxury will help ensure suitable lighting for the function of each space, while avoiding waste of energy in the family.
Calculating the total optical fiber
After determining the standard lux, it is necessary to calculate the total optical fiber (lumen) needed for the space using the standard formula. For example, a 20m2 living room with a standard luxury of about 300 will need a total brightness of 20x300 = 6,000 lumen.
Accurate calculation of total optics will help housewives choose the right number and type of light to ensure adequate light supply and energy saving.
Choosing the right light number
Each type of lamp has different output and output, usually measured in lumen per watt (lm/W). For example, if you use an LED light with a brightness of 600 lumen, to reach 6,000 lumen, you need about 10 lights. Choosing high-performance lights will help reduce the number of lights needed, saving costs and energy.
Factors affecting lighting efficiency
In addition to the above technical factors, the house also needs to pay attention to a number of other characteristics that will affect the lighting efficiency. For example, interior color, dark walls and ceilings will absorb more light, need to increase lighting intensity or use higher optical lights; or ceiling height, if the ceiling is higher than normal, will reduce luxury on the surface, so housewives can use lights with higher capacity or increase the number of lights.
