The kitchen belongs to home lighting, home lighting to meet the basic illuminance requirements of about 100lx, the illuminance of home lighting is a reference suggestion, unlike public space lighting, such as library lighting, etc. is a mandatory requirement.
The overall illumination of the kitchen is about 100lx, and the value range can be about 75-150lx. For working surfaces such as countertops, vegetable sinks and other places, it is recommended to use an illumination of about 200-500lx.
Let's assume that the kitchen area is 3 meters * 4 meters, which is about 12 square meters.
The formula for calculating the average illuminance is: average illuminance = luminous flux of lamps and lanterns Number of lamps and lanterns Space utilization coefficient Number of maintenance and room area
The space utilization coefficient and maintenance coefficient of the kitchen are slightly lower, 07 and 08 bar.
The luminous flux of the lamp is about 2132lm, assuming that the luminous efficiency of the lamp is 80lm w, the specific amount needs to consult the manufacturer, and the power is 2678W, that is, about 30W LED lamps are fine. There is nothing wrong with a little brighter kitchen.
It is generally recommended to use a combination of panel lights + downlights, you can install a panel light of about 18W in the kitchen, and then install 2 downlights of about 6W above the working surface on the operating surface and the vegetable sink.
The panel light has a large glossy surface, and the light is uniform and comfortable.
Then use a downlight with a comfortable light mark, high light efficiency and high color rendering above the working surface, which can increase the illuminance to about 200-300lx.
Of course, if you think this is more troublesome, you can use a simpler method, and the kitchen can be about 3w per square.
