Functional division
Lamps with different light sources are suitable for different places. For example, ceiling lamps using ordinary incandescent bulbs and fluorescent lamps are mainly used for lighting in places with a floor height of about 4 meters such as homes, classrooms, and office buildings. Intensity gas discharge lamps are mainly used for lighting in stadiums, hypermarkets and factories with a floor height of 4 to 9 meters. In order to achieve sufficient height for the work surface while saving electricity, fluorescent ceiling lights are often the first choice for lighting in homes, schools, shops and offices.
