Meeting room, training room, maintenance room and other spaces with simple visual requirements: low-grade 200lx, medium-grade 300lx and high-grade 500lx.
Lighting layout can be divided into three types, namely basic lighting (ambient lighting), accent lighting, decorative lighting and emergency lighting. Basic lighting is generally used in offices, while some places such as home and some clothing stores will use some lighting methods combining the three. The specific lighting method depends on the scene.
Selection of light source type:
(1) If there are no special requirements, gas discharge lamps with high luminous efficiency should be selected as far as possible. When incandescent lamps are used, the power should not exceed100W. ..
(2) Fluorescent lamps should be used in lower rooms (below 4~4.5m), and HID lamps should be used in higher places.
(3) fluorescent lamps are mainly straight tubes, and single-ended and self-ballasted fluorescent lamps (compact) can be used when necessary (such as decoration); Straight fluorescent lamps have higher light efficiency, longer service life and more stable quality; The advantages of self-ballasted fluorescent lamps are that most of them use rare earth tricolor powder and there are many electronic ballasts.
(HID lamps should use metal halide lamps and high-pressure sodium lamps, and generally do not use mercury lamps. Metal halide lamps are superior to high-pressure sodium lamps in color rendering and spectral characteristics, and have better visual effects in most places.
