Selection of lighting principles

Lighting design, select meet the requirements of function and the lighting quality, ease of installation and maintenance, low long-term operating costs of lamps, you should consider the following aspects:

(1), optical characteristics, such as light distribution and glare control;

(2), economy, luminaire efficiency, the initial investment and long-term operating costs;

(3) and special environmental conditions, if there is risk of fire and explosion dangerous environment, dust, humidity, vibration and chemical corrosion environment;

(4) should coordinate with the building, lighting appearance;

(5), the luminous efficiency (η) high: η = φ φ o/l, depending on the reflector shape and material, light, diffused reflector and grille shape or materials;

(6) the IP level, in line with environmental conditions.
