The bedroom is a place of rest, and all that is done is with lighting that helps you rest and sleep. The color temperature and brightness of the lights can be lower, which is conducive to creating a resting and relaxing environment. The wattage of the bedroom ceiling lamp has a large relationship with the area of the room, generally speaking, roughly calculated, the bedroom can be about 3 watts a square. The color temperature and brightness of Japanese lamps may be on the high side, which can be about 2w per square. And the bedroom is a more personal place, and the most important thing is that you like it and feel comfortable.
If according to the illuminance standard, there are two main application scenarios in the general bedroom, one is the general daily activities, mainly rest and relaxation, the illumination is about 150lx, and there may be a situation where the control degree requirements are relatively high for reading, then the illuminance should be 300-500lx. At this time, you can actually choose to use a floor lamp or bedside lamp as an auxiliary lighting to improve the brightness of the basic lighting.
The formula for calculating the average illuminance is:
Average illuminance (e**) = luminous flux of the luminaire * space utilization coefficient (cu) * maintenance factor (k) area (s).
The luminous flux of lamps and lanterns is generally provided by the outer packaging of lamps or manufacturers, and the space utilization coefficient involves many influencing factors, such as lamp design, house height, reflectivity of room walls and floors, size, etc. Generally speaking, it is used indoors, with a floor height of about 3 meters, white walls, and wooden floors, and its utilization coefficient is 06-0.7 or so, and the maintenance coefficient is generally 07 or 08。Accurate values require the manufacturer to provide relevant data and make accurate calculations.
For example, if the bedroom is 10 square meters, the space utilization factor is set to 065, the maintenance factor is 08. If the luminous flux of the lamp is 2400lm.
The average illumination value of the room is 125lx, which basically meets the lighting requirements of the bedroom.
If it is a bedroom for the elderly, the eyesight of the elderly is weakened, and the brightness can be increased a little, which is more conducive to the elderly to see things clearly.
It is also necessary to pay attention to the size of the lamp, it is generally recommended that the diameter of the lamp is one-tenth to one-eighth of the diagonal length of the room, and it is too large or too small to appear not very harmonious with the room.
