Simple principle
Lighting should play a finishing touch in the room. Overly complicated shapes and overly complicated colors are not suitable for designing simple rooms.
Convenience principle
Most people have experienced the shackles of replacing the ceiling light bulb: stepping on the table, stepping on the chair, heading 90 degrees, raising his arms over the head to a height of 2. 5 meters or even higher. When choosing a luminaire, it is important to consider replacing the lamp.
Energy saving principle
The energy-saving light bulb saves electricity and has good illumination, and it will not emit too much heat. It is suitable for multi-head lamps. Energy-saving bulbs are mostly standard screws, and chandeliers are available in two sizes, one is standard and can use energy-saving bulbs; one is non-standard and cannot use energy-saving bulbs. Be careful when choosing: Spotlights are mostly non-energy-saving products.
Safety principle
Be sure to choose the lamps of regular manufacturers. Regular products are marked with total load. Depending on the total load, it is possible to determine how many wattages to use, especially for multi-head chandeliers, ie: number of heads × watts per bulb = total load. In addition, the bathroom and kitchen with large moisture should use waterproof lamps.
Functional principle
For different rooms with different functions, different styles and illuminations should be installed. The living room should use bright and rich lamps; the bedroom should use lamps that make people lie on the bed; the children's room should use colorful and varied lamps; the bathroom should use simple waterproof lamps; the kitchen should be convenient. Wipe and clean lamps; some places that require special performance can also choose spotlights.
