This standard specifies the safety requirements for ventilated luminaires using ventilation ducts or openings for ventilation (forced ventilation). The lamps use tubular fluorescent lamps as the light source, and the power supply voltage does not exceed 1000V. This standard should be read together with GB 7000.1-1996 "General Safety Requirements and Tests for Lamps". It should be noted that this standard only stipulates the safety requirements of ventilated luminaires, and does not specify the performance requirements. Notes: 1 The terms "ventilated" and "ventilated" in this standard refer to forced ventilation. 2 This standard does not impose requirements on the use of tungsten filament lamps and gas discharge lamps other than tubular fluorescent lamps.
