The light source should be selected based on the characteristics and requirements of the production process. Suitable light sources include electrodeless lamps (see this entry for details on electrodeless lamps), tri-phosphor thin-diameter straight fluorescent lamps, metal halide lamps, or high-pressure sodium lamps. Electrodeless lamps and thin-diameter fluorescent lamps are recommended when the light source is 4m or less above the ground; electrodeless lamps and metal halide lamps can be used in higher factory buildings (above 6m); high-pressure sodium lamps can be used where color rendering is not required.
Electrodeless Lamps:
1. Places where lamps are frequently switched on and off and require instantaneous starting;
2. Places with overhead cranes where glare needs to be avoided;
3. Places with long lamp usage times and high power consumption where energy saving, power saving, and cost saving are required;
4. Places requiring strict color identification (such as spectral analysis rooms, chemical laboratories, etc.).
Incandescent Lamps:
(1) Places with strict requirements for preventing electromagnetic interference.
(2) Places where lamps are frequently switched on and off.
(3) Places with low illuminance requirements and short lighting times.
(4) Localized and temporary lighting.
High color rendering tri-color fluorescent lamps are recommended for locations requiring strict color identification (e.g., spectral analysis rooms, chemical laboratories).
High-power rocket launcher energy-saving lamps:
(1) Locations where lamps require frequent switching and instantaneous start-up;
(2) Factory height below 10 meters, preferably 4-8 meters;
(3) Locations with high electricity consumption requiring energy saving, power saving, and cost saving;
(4) Locations with a long lamp lifespan, generally 3-5 years;
(5) Locations requiring high realism (e.g., precision machinery, spectral analysis rooms, chemical laboratories).
Ceramic metal halide lamps:
(1) Factory height above 10 meters;
(2) Locations with high illumination requirements;
(3) Locations with high electricity consumption requiring energy saving, power saving, and cost saving;
(4) Locations requiring high realism (e.g., precision machinery, spectral analysis rooms, chemical laboratories).
