DISPLAY LIGHTING ARRANGEMENT

摘要

A lighting arrangement includes a spot light (13) supported within a tapered duct (20) which is mounted in a housing (15) by means of an eye-ball bearing. A pressurising unit (31) and a booster unit (32) produce a flow of air along the duct in the direction of light emission. The reflector (12) of the spotlight constricts the air flow path producing a convergent jet of cooling gas in front of the spot light.
