Illumination device for opening up of construction work and enhancing construction of the clockwork with such a lighting device and method for operating a lighting device of a development of construction work

摘要

The invention relates to an illumination device (100) for a development of construction work, in particular elevator shaft or tower of a wind power plant. The illuminating device consists of a plurality of lamps (210, 220) as lighting means of which one behind the other and with a distance (230) are arranged relative to one another and with electrical lines (240, 250) are connected. The lines (240, 250), and the lamps (210, 220) are in a transparent and flexible casing (200) is arranged. The present invention also relates to a development of construction of the clockwork with such an illuminating device (100) and a method for operating a lighting device (100) of a development of construction work. The object of the invention, it is the disadvantages of the prior art to be overcome, to provide a possibility to provide an emergency lighting the simple and / or is to be installed at low cost, the emergency lighting is to have a high degree of operational reliability. According to the invention for this purpose, it is provided that the lamps (210, 220) to at least two groups (310, 320) and are combined in the housing (200) at least one additional electric line (260, 270) is arranged, wherein at least one of the lines (250, 260, 270) solely with the lamps (210, 220) of one of the groups (310, 320) is connected. It is also inventively provided that, in the case of the illuminating device (100) in an emergency operation at least a portion of the lamps (210, 220) of an auxiliary voltage source (410) is supplied.
