Preferably, the lamp has a housing element in which both the

Light emitting means, as well as the control means are arranged. This is beneficial with Reference to a particularly simple control of the light emitting means by the control means, as well as with respect to the manufacturing cost of the lamp.

Preferably, the control means are exclusively for controlling the

Light emitting means designed. This makes the lamp particularly easy to design. Preferably, the control means are designed to operate autonomously.

Preferably, the luminaire further comprises a brightness sensor for detecting an ambient brightness, wherein the brightness sensor for generating the

This makes it particularly easy to provide the presence information. Preferably, the luminaire has a clock, wherein the clock is designed to generate the time information. This makes the time information particularly easy to make available. Alternatively or additionally, the control means are preferably connected to the Internet and / or a broadcasting, in particular for generating the information relating to the daylight and / or the time information.

Preferably, the lamp has a control for manual off and

Turn on the control means and to manually turn on and off the

Light-emitting means. Thus, the automatic control of the light emitting means can be manually overwritten if necessary, so to speak.

Preferably, the lamp is a floor lamp or a

Pendant light.

The invention is explained in more detail below with reference to an embodiment and with reference to the drawings. Show it: Fig. 1 is a sketch of a lamp according to the application and Fig. 2 is a functional sketch for controlling the lamp.

In Fig. 1 is a perspective sketch of a lamp according to the application, shown here by way of example in the form of a pendant lamp. The lamp points

Light emitting means 1 for generating a first light output and a second light output, wherein the second light output differs from the first light output. The light-emitting means 1 may comprise LEDs, for example.

Preferably, the lamp comprises a housing element 9, in which the

Light emitting means 1 are arranged. In the case of a pendant lamp, the housing element 9 may be configured to be attached or suspended via suspension elements on a support, for example in the form of a room ceiling.

For example, the design may be such that the first light output and the second light output each comprise a first, upward light portion 7 and a second, downward light portion 8, wherein the second light output from the first light output in the ratio between the intensity of the second light component 8 differs from the intensity of the first light component 7. With the first, upward light portion 7 can be an indirect lighting of a room achieve, with the second, downwardly directed light compartment 8 direct lighting. The two light outputs thus differ in the ratio between the indirect illumination to the direct illumination.

Furthermore, for example, the design may be such that the two light outputs differ in a color and / or a color temperature and / or in the intensity of the emitted light. It can also be provided that the two light outputs differ in a so-called accent light. A combination of the mentioned differences can also be provided.

Further preferably, the design is such that the light emitting means 1 also for generating a third light output and in particular beyond are still further light outputs designed, with the same applies to the third and the other light outputs and the corresponding differences as for the first light output and the second light output. In this way, with the light several - especially more than two - create different lighting moods.

Furthermore, the luminaire comprises control means 2 for activating the light-emitting means 1. FIG. 2 outlines a functional sketch for controlling the luminaire, in which the control means 2 are symbolically sketched in separated form. The control means 2 are further configured to acquire input data 3, wherein the control means 2 are designed to drive the light emitting means 1 in response to the input data 3, such that the light emitting means 1 generate either the first light output or the second light output. This is indicated symbolically in FIG. 2 by two thick arrows.

In this case, the input data 3 comprises time information 4, information 5 relating to the daylight, and presence information 6.

The information that the luminaire takes into account can therefore be divided into three different categories.

The time information 4 may include, for example, the time of day and / or the season or the like. In this way it can be achieved that corresponding information is taken into account by the luminaire, on the basis of which a time is determined by the control means 2, at which the light emitting means 1 are switched on and, for example, an adjustment of the color or color temperature of the emitted light is undertaken.

In particular, the control means 2 may have a preprogrammed schedule for the control of the light emitting means 1. The schedule may, for example, relate to the intensity of the emitted light. Additionally or alternatively, the schedule may relate to the color and / or the color temperature of the emitted light. Additionally or alternatively, the schedule may relate to the ratio between the intensity of the second light component 8 and the intensity of the first light component 7. By doing Timetable may include, in particular, a time of sunrise and a time of sunset.

The information concerning the daylight 5 is of particular importance when the luminaire is positioned in an area which is influenced by daylight entering from the outside. Here it plays a role, whether it is sunny or the sky is covered or whether it rains and the like. Depending on this, the type and distribution of the incident light from the outside can change, which can then be taken into account by the light accordingly. For example, it can be provided that by appropriate control of the light emitting means 1 by the

Control means 2, the ratio between the intensity of the second light portion 8 is changed to the intensity of the first light portion 7 in response to the information relating to the daylight. In the third category, the presence information 6 or presence information, it is important whether and, if appropriate, how many persons are located in an area illuminated by the luminaire. The presence of a single person, for example, indicates that they are working or reading or working at a desk if they are permanently in the area. If, on the other hand, several persons are responsible, a meeting or the like could take place here, possibly requiring a different type of light delivery. For example, it can be provided that by the control means 2 the

Light emitting means 1 are kept switched off, as long as according to the presence information 6 no person is in an environment of the lamp.

These three categories mentioned represent the basic information, on the basis of which the light output of the luminaire is then changed or adjusted accordingly by the control means 2. Optionally, however, could be additional

Information such as the brightness in an area to be illuminated and / or the volume or the like.

To provide the control means 2, the input data 3, can

For example, be provided that the lamp has a brightness sensor for detecting an ambient brightness, wherein the brightness sensor for generating the the daylight information is designed. Alternatively or additionally, it may be provided that the luminaire has a presence sensor, wherein the presence sensor is designed to generate the presence information.

Alternatively or additionally, it may be provided that the luminaire has a clock, wherein the clock is designed to generate the time information.

However, it is not absolutely necessary that the luminaire has a corresponding sensor or a clock, because it can also be provided alternatively or additionally that the luminaire is transmitted by other means, in particular wirelessly or the like, corresponding input data. For example, it may be provided for this purpose that the control means 2 are connected to the Internet and / or a broadcasting, in particular for generating the information 5 relating to the daylight and / or the time information 4.

In any case, however, it is provided that said information 4, 5, 6 or the input data 3 are evaluated and processed accordingly by the luminaire itself and then the luminaire autonomously adjusts a specific way of emitting light. Accordingly, the control means 2 are preferably designed to operate autonomously. The control means 2 are preferably configured exclusively for controlling the light-emitting means 1, that is, in particular not for controlling further light-emitting means, for example a further light. Preferably, the control means 2 are arranged in the housing element 9.

The design could also be such that the luminaire can emit an additional accent light or the like; This, too, can then optionally be adjusted as a function of the information available to the luminaire 4, 5, 6.

In Fig. 2, the light - as far as alternative to the embodiment shown in Fig. 1 as a pendant - sketched as a floor lamp. This may have a lamp post 11 which is fixed to a lamp base 12, wherein the lamp base 12 serves as a base of the lamp. On the other hand, on the lamp post 11 a

Luminaire head 13 attached, which forms the housing element 9 of the lamp here. As further sketched by way of example in FIG. 2, it can be provided that the luminaire also has an operating element 10 for the manual switching on and off of the control means 2 and for the manual switching on and off of the light-emitting means 1. Thus, it can be achieved, in particular, that the actuation of the light-emitting means 1 by the control means 2 is as it were overwritten by actuation of the operating element 10.

With a luminaire according to the application, it is thus possible to achieve that it can autonomously and autonomously respond to corresponding information and, adapted thereto, effects a corresponding light emission. With a luminaire according to the application, a suitable illumination can be provided automatically at a reasonable cost depending on external influences. If several lamps according to the application are operated in one room, it is possible by appropriate programming to achieve a light output of the lamps, which to this extent is coordinated with each other.
