Recommendations for the selection of household indoor lighting fixtures:
There are many styles of lamps, but try to avoid chandeliers. Although the shape is good-looking and the light is turned on, it is very atmospheric, but it is difficult to clean. Especially for crystal lamps, the hanging crystal beads are seriously dusty, and it is difficult to remove them by yourself.
1. Select spotlights, downlights, ceiling lights, not chandeliers
There are many styles of lamps, but try to avoid chandeliers. Although the shape is good-looking and the light is turned on, it is very atmospheric, but it is difficult to clean. Especially for crystal lamps, the hanging crystal beads are seriously dusty, and it is difficult to remove them by yourself. It costs a lot to ask someone to wash them. Moreover, this kind of chandelier is hung down and the layer height is high. Unless the layer height is more than 3 meters, it is not recommended to choose it.
Like the current commercial housing, it is more suitable to choose spotlights or downlights. Whether it is decoration or lighting, it can achieve the effect. The ceiling lamp is simple and elegant, easy to install, very suitable for small rooms with insufficient floor height.
2. Choose warm colors instead of cool colors
The color temperature of the light source of the lamp affects the comfort of the living room. It is recommended to choose warm colors and avoid cool colors. Warm colors give people a sense of intimacy and comfort, while cool colors are clear but always have a sense of alienation, which is not suitable for home atmosphere. Generally, the indoor color temperature of 3000-4000K is the most suitable.
3. Select color rendering > 90, not less than 90
Color rendering (Ra) sounds very professional, but it actually refers to the true degree of color displayed by the light shining on the object. Under normal circumstances, the lower the color rendering, the more unrealistic the color, and the human eye is easy to get tired after watching it for a long time.
Therefore, when choosing lamps and lanterns, pay attention to its color rendering index, which is usually marked. It is recommended to choose lamps with Ra>90, which are more suitable for home use.
4. Choose the right wattage instead of high wattage
The wattage determines the brightness of the lighting. Since different areas of the room have different lighting requirements, you cannot blindly believe that high-wattage lamps are good, and the wattage should be selected reasonably according to the actual situation.
5, wattage selection
The wattage of the living room should be selected according to the specific area, which can be calculated according to 2.5-3w/㎡. For example, 20-30㎡ choose 60-80w, 40-50㎡ suggest 220-280w, etc. The kitchen, like the living room, is calculated according to the formula. 3-5㎡ choose 8-13w, 5-10㎡ is recommended to choose 13-25w.
Choose 16W lamps in the bathroom, and you can buy induction lamps for auxiliary lighting, which is convenient for use at night. The bedroom is dominated by soft light sources, it is recommended to choose 13-25w; if the room is large, you can choose 38-50w.
