Embodiment Construction
[0052] Figure 1a and 1b The use of a room dividing lighting device 120, 122 according to the first aspect of the invention in a privacy mode of operation is schematically shown. For example, space 102 is an open office. In the space 102, a first person 106 is sitting at his desk 121 and does not wish to be disturbed since he has to concentrate on his work. Thus, a first person 106 wants a kind of sub-space 104 around his desk that is somewhat separated from space 102 . The first person 106 does not want the second person 114 and the third person 118 to be too close to his table, which means he does not want the second person 114 and the third person 118 to enter the subspace. If the other persons 114, 118 are not too close, he is not distracted by their presence and it is more difficult for the second person 114 and the third person 118 to start a conversation with the first person 106 . According to a first aspect of the invention there is provided a room dividing lightin...

Abstract
A room dividing lighting device 120, 122, the use of the room dividing lighting device and a method of installing the room dividing lighting device are provided. The room dividing lighting device 120, 122 comprises a light emitting means. The room dividing lighting device 120, 122 is used for separating a subspace 104 from a space 102 to prevent a person 114, 118 from coming close to or entering the subspace 104 in a privacy operational mode of the room dividing lighting device 120, 122. The light emitting means emits light in an upward direction and is configured to emit, in a privacy operational mode, glary light in a light beam 108 for hindering the person 114, 118 who enters the light beam 108 or crosses it with his eyes 112, 116. The light emitting means comprises at least one light source and a light redirection means. The light redirection means receives light from the at least one light source and is configured to redirect, at least in the privacy operational mode, the received light in the light beam 108.
Description
technical field [0001] The invention relates to a room-dividing lighting device for separating sub-spaces from spaces. Background technique [0002] Typically in an office, a relatively large number of people work in a single room. In particular, it is relatively difficult in an open office to prevent people from being disturbed by other people present in the same open office. Traditionally, cubicle dividers have been placed around the desks of people who do not wish to be disturbed or who require a certain amount of privacy. [0003] Published patent application US2010 / 0177533 discloses a privacy panel which can be used to obtain privacy for persons located behind the privacy panel. In a specific embodiment of the privacy panel, the privacy panel is a transparent panel positioned between the person requiring privacy and other persons. The transparent plate comprises light sources arranged at least at one edge of the transparent plate, and if the light sources are in oper...
