FIELD: lighting. ^ SUBSTANCE: invention concerns of time, temporary, essentially emergency lighting facilities and can be applied at night construction and roadway maintenance works in case of power outage, at emergency recovery operations. Plant contains support with in-built air-supply passage under pressure, support fastener to ground or bearing surface structure. Air flexible bag with inlet opening is attached to support. In front of inlet opening there is air valve connecting bag cavity to air source through air-supply passage. Light source is mounted inside of bag. Bag is provided with curvature and shaper modifier. Internal surface of bag section behind horizontal symmetry axis towards support is light-reflecting. Transmission ratio of bag reflecting sector is lower than transmission ratio of bag sector that is opposite to bag reflecting sector. Bag is separable connected to hollow-core and tubular support. Said air-supply passage is mounted within its cavity. ^ EFFECT: enhanced performance of lighting plant with provided displacement of light spot within illuminated surface and modified geometry of light spot. ^ 10 cl, 32 dwg |
