Ceiling with consumption of essential knowledge
1, lamp installation of the building known as the ceiling close to the ceiling with lamps, ceiling lamps used to provide indoor environment with illumination. Indoor lamp light source can be used with ordinary incandescent light bulbs, fluorescent, high intensity discharge lamps, tungsten halogen lamp and so on. The ceiling light with a different application of different places, use the ceiling with fluorescent and incandescent lamps used in home, classroom, office and other space-storey 3-meter premises lighting, power and light source larger high-intensity gas discharge lamp is mainly used for sports venues, large shopping malls and factory floor such as the height of 4-9 meters places Lighting. Energy-saving at the same time in order to get enough brightness in the face, home, school, shops and office lighting products are the first choice for a fluorescent ceiling. Been widely used in a fluorescent ceiling should meet basic safety requirements.
2, the main safety requirements and electromagnetic compatibility requirements
(1) lamp wiring cross-sectional area of internal / external wiring cross-sectional area should be larger than 0.5mm2/0.75 mm2.
(2) The lamps should be durable to use. The use of fluorescent lamps should be used not only in the normal state to resume normal work, and in the event of lamp aging, damage to the case provides an exception to protect the ballast. Incandescent bulb lamp shell, lamp shade, insulation, etc. In the endurance test lamp should not burnt, not deformed.
(3) sufficient electrical creepage distance and clearance.
(4) The lamps in the main safety components, insulation material should be heat-resistant, fire-resistant.
(5) The lamps should have sufficient protective measures against electric shock.
(6) The lamps should have a reasonable structural design and integrity of the processing technology.
(7) lights of electromagnetic disturbance shall be within the limits specified in the standard.
(8) lamps harmonic currents should be within the limits specified in the standard.
