Problems solved by technology

In certain applications, however, the luminaire needs to be assembled in the case of a high space at a short distance from the ceiling or at a great distance from the ceiling, which on the one hand leads to undesired heights on the ceiling side. Luminous density, which would be detrimental to the installation of such luminaires and thus limit the operational possibilities, or on the other hand would result in too low a luminous density on the ceiling side at large suspension heights and would be desirable in the space The proportion of indirect light becomes too small

Embodiment Construction

[0029] The main part of the luminaire denoted by reference numeral 1 as a whole includes a housing 2 having a first light emitting area 4 on its emission side, that is, on its side facing the space 3 to be illuminated. A light emitting area in the luminaire 1 of this exemplary embodiment extends substantially over the entire side of the housing 2 facing the space 3, and thus preferably extends in the emitting surface E1.

[0030] The housing 2 encloses the housing internal space 5 by the light-transmitting bottom wall 2a on the emission side, the opposite side wall 2b, and the rear wall 2c opposite to the first emission area 4, in which the internal space of the housing passes not shown At least one connecting device 6 for at least one lamp 7 connected to a power source is provided and fastened to, for example, the inner wall of the housing. The lamp 7 may be, for example, a so-called fluorescent lamp, and an operating device 8 is associated with the power source of the lamp. The...

Abstract

The light (1) has a housing (2), and a light emission region (4) with a light influencing element (9) provided at one side of the light. Another light emission region (21) with another light influencing element (22) is provided at another side of the light for direct lighting. The another light influencing element is adjustable in two different positions (S1,S2)

Description

Technical field [0001] The invention relates to a luminaire according to the preamble of claim 1. Background technique [0002] In the case of this type of luminaire, the luminaire is of a known design, especially previously known as a suspended luminaire. The important feature of the luminaire is that it has a first light emitting area on one side of its housing for direct lighting of the space, and a first light emitting area for indirect lighting of the space and arranged on the luminaire. The second light emitting area on the back side opposite the area. The purpose of the second light emitting area with the light-transmitting light influencing element is to illuminate the periphery of the illuminator at the side and / or the rear to reduce the light intensity between the first light emitting area and the periphery of the illuminator Differences, and / or indirect lighting in addition to direct lighting, particularly at the rear of the luminaire, improves the lighting of the sp...
