The lamp consists of at least one electric light bulb (22) inside an inflatable transparent envelope (11) with an inflation system (13) including a fan (15), and a power supply. The bulb and fan assembly are surrounded by a transparent or translucent plastic cover (25) that acts as a flameproof insulating screen and an deflector for incoming air that cools the bulb(s) and inflates the envelope through apertures (28). The apertures are located at the upper end of the cover so that the balloon is inflated through the top, and the base of the cover has an open rim (26) that engages with a thrust surface on a support. A thermostat cuts off the power supply to the bulb(s) if the fan stops working. |
