Principles of selecting lamps

Principles of selecting lamps

    In lighting industry, you should choose lamps that not only meet the requirements of using functions and lighting quality, but also are easy to install, maintain and have low long-term operating costs. The following aspects should be considered:

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

(2) Economics, such as lamp efficiency, initial investment and long-term operating costs;

(3) Special environmental conditions, such as fire danger, explosion danger, dust, humidity, vibration and chemical corrosion environment;

(4) The appearance of the lamps should be coordinated with the building;

(5). High efficiency (η): η = ΦL / ΦO, depending on the shape and material of the reflector, the size of the light outlet, the shape and material of the diffuser cover or grille;

(6) IP rating that meets environmental conditions.
