摘要

#CMT# #/CMT# The unit has an assembly provided for fixation of the unit to a wall or ceiling and comprising a cover (9) and a case (8) that are connected together by transversal movement. A diffuser casing (1) having an electronic circuit is mounted on the cover in a manner to rotate around a pivot axis. A passage section is formed in the casing and the cover at the height of the pivot axis. #CMT# : #/CMT# Independent claims are also included for the following: (A) utilization of a lighting unit as an emergency lighting system (B) utilization of a lighting unit as a signaling system (C) utilization of a lighting unit as a walk light system. #CMT#USE : #/CMT# Used as an emergency lighting system, a signaling system and a walk light system (claimed). #CMT#ADVANTAGE : #/CMT# The diffuser casing having the electronic unit is mounted on the pivot axis, so that the casing can be pivoted to the desired position easily for adjusting the angle and direction of diffusion of light and hence the space to be illuminated can be controlled in a simple and easy manner. The passage section is formed in the casing and the cover at the height of the pivot axis, thus permitting to pass electric connection cables from the cover towards the electronic circuit without any damage of the cables due to the rotational movement of the casing. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side view of a lighting unit. 1 : Diffuser casing 4, 5 : Lateral sides 8 : Case 9 : Cover 10, 11 : Arms.
