Supply units is the housing for receiving

Gas lines and electrical lines suitable. The

Housing is elongated in a longitudinal direction, which means that the housing has a substantially greater extent in the longitudinal direction than in the perpendicular to the Longitudinally aligned transverse direction. The ratio between the longitudinal extent and transverse extent of a housing may in some embodiments be 5: 1, in some

Embodiments 10: 1 or larger. For further features of the profile-like housing of

Conventional generic supply units, reference is made to the documents EP 1 073 172 B1 and EP 1 096 629 AI, in particular to [0001] to [0003], [0008] to [0014] and the description of the figures of EP 1 073 172 B1 and [0002 ] to [0003], [0007] to [0010] and the description of the figures of EP 1 096 629 A1.

Generic supply units have at least one luminaire with at least one luminous means unit which comprises at least one luminous means. In particular are

Supply units known which at least one

Have lamp unit comprising a plurality of lighting means, in particular in a section in

Longitudinally arranged side by side. The

Illuminant unit may for example be designed so that it allows a room backlighting, in other examples, the lighting unit may emit light in a certain area of space, for example, to ensure the function of a reading light.

Usually, the lighting unit is arranged in the housing of the supply unit or has its own

Illuminant housing, which is connected to the housing of the

Supply unit is connected. The number of

Illuminant of the lighting unit and the arrangement of the light source in the lighting unit is depending on the desired, to be achieved with the light-emitting unit

Purpose set. The illuminant unit may in particular comprise at least two bulbs arranged side by side in the longitudinal direction. The portion in which the bulbs are arranged extends along the Longitudinal direction. The lighting means can also be arranged offset from each other in the transverse direction, in particular can across the transverse direction and the longitudinal direction of a surface

be stretched in which distributes the bulbs

are arranged. In particular, the lighting means can also be arranged one above the other in the transverse direction, such rows being arranged one above the other in the transverse direction

Lamps can be arranged side by side in the longitudinal direction. In addition, a control unit for controlling the at least one lighting unit is usually provided in the supply unit, in particular in the lamp, via which at least the switching on and off of the lighting unit is controllable.

A special further development of conventional

Supply units is known from document EP 0 739 618 B1. In this supply unit is the

Bulb unit arranged displaceably in the longitudinal direction of the housing of the supply unit, so that the position of the illuminated by the light emitting unit in the room area is correspondingly displaceable over a displacement of the lamp unit in the longitudinal direction. In this supply unit is thus a displaceability of the illuminated area for adjusting the illumination of the furniture arrangement in the room and the desired by persons in the room illumination characteristic possible. This takes place in this supply unit via a mechanical displacement of the lamp unit along the housing of the supply unit.

The described conventional supply units have several disadvantages. First, it is at the

described supply units only possible with the help of an additional dimming device, the

Illumination intensity, ie the intensity of the Illuminant units of the supply unit radiated light, to vary, so that the illumination intensity does not correspond to the particular situation in the room, such as

For example, a reading situation, a situation in which a weak backlight is desired, or an investigation situation in which a doctor a

Patients, for example, in his patient bed, in a room examined, can be adjusted. In addition, a shift of the one or the other

Illuminant units of the supply unit illuminated area only via a mechanical displacement of the

Bulb unit along the housing of

Supply unit done. For this purpose, a costly mechanical storage of the lighting unit or the

Illuminant units are required on the housing of the supply unit, and the shift is not usually by a patient lying in the bed itself

feasible but must be performed by a nurse. In addition, such storage of lighting units connected to the housing with hygienic disadvantages, since the storage can not be kept clean as desired.

The invention is based on the object

Supply unit to provide the above

described problems in known supply units at least partially corrects.

As a solution of said technical problem, the invention proposes a supply unit with the features of claim 1. The supply unit according to the invention is characterized in that within the section in which the lamps in the longitudinal direction side by side

Longitudinal direction. In this embodiment, the

Illuminant groups arranged side by side in the sense that the longitudinal centers of the lamp groups are arranged side by side. In one exemplary embodiment, all the lighting means groups have the same longitudinal length. In one embodiment, a plurality of lighting units are provided, which are offset from each other in the transverse direction. For example, at least some of the

Light emitting units of the supply unit emit light in a respective other emission direction. In one

Embodiment, the supply unit has a plurality of lamp units, wherein the lamp units are arranged offset from one another in the longitudinal direction. In one embodiment, the staggered arrangement of the illuminant units may consist in that illuminants of one illuminant unit are arranged offset to illuminants of the other illuminant unit. In one Embodiment overlap the

Bulb units in the longitudinal direction not. In one

Description in relation to the invention

Supply unit as preferably contained

have described features. The supply unit according to the invention may comprise a plurality of lights according to the invention, each having different feature combinations according to the invention. For example, the Supply unit according to the invention or one of the lights of the supply unit according to the invention comprise a control unit, via which the control of all lights of the supply unit is ensured. The control unit enables independent control of the different groups of lamps. As a result, one or more specific groups of lamps can be selected in a targeted manner via the control unit, so that only these groups of lamps emit light. Thus, via the control unit, a desired emission characteristic and / or a desired illumination range, which is ensured by the lighting means of the supply unit, can be set. Thus, in the case of the supply unit according to the invention, the illumination characteristic can be adapted to the respective situation and the respective wishes of the person in the room, without having to mechanically influence the supply unit and / or the lighting unit. Rather, the emission characteristic can be adjusted purely electronically via the control unit. As a result, the supply unit according to the invention brings considerable advantages. For example, a simple and inexpensive mounting of the lighting unit to the housing of the supply unit may be possible. For example, a very simple setting of the

Radiation characteristic of the bulbs of the

Supply unit emitted light be possible.

For example, the setting can be over

Actuator done electronically with the

Control unit is connected. This allows a person, such as a patient or a nurse, on actuation of the actuator influence on the

Illumination of the room. In addition, the supply unit according to the invention ensures hygienic

Advantages because the supply unit are formed in this way can be easily kept clean because no complicated mechanical bearings are necessary, which connect the lamp unit or the lamp units to the housing of the supply unit. In a particularly advantageous embodiment are as

Bulb LEDs provided. Due to their compact design, LEDs can be integrated into the supply unit in a particularly simple and visually appealing way. In addition, LED modules are particularly easy to control electronically. In one embodiment, the lighting unit is as

LED strips formed, wherein the LEDs in groups, d. H. as lighting groups, can be controlled separately. In particular, when using LEDs as the light source, it is possible to produce the illuminant unit separately from the supply unit as a complete LED module and to tune it to a control unit, so that the production of the invention

Supply unit can be particularly simplified, since only an integration of the complete LED module needs to be implemented in the supply unit, the LED module already with the control unit of the

Supply unit is tuned. In one

Embodiment, LEDs with different

Be provided light colors. In one exemplary embodiment, various illuminant units are provided, which each have exclusively LEDs with a specific light color. As a result, for example, a different light color can be ensured in different emission areas. In one embodiment, light-emitting device groups are provided in the lighting unit, which have LEDs with different light color. By the separate control of the lighting groups can

for example, the color with which the room in which the supply unit is arranged is illuminated, be changeable.

In an advantageous embodiment, the control unit is designed so that a lighting section in a certain longitudinal section length can be predetermined, within which the control unit activates the light emitting means for emitting light, wherein the longitudinal position of

Lighting section is adjustable via the control unit. In particular, the longitudinal section length and the longitudinal position for a particular lamp unit, in particular for different lamp units, can each be individually, adjustable or specifiable. These

For example, the embodiment can bring the advantage that a user can reduce the length of the

Lighting section, and thus the length of the section, in the light source of the lamp unit light

emit, can pretend and a shift of

Can realize lighting section in the longitudinal direction. For example, the longitudinal section length of the

Lighting section with a change in the

For example, the control unit may be set so that between the longitudinal section length of the lighting section and the longitudinal position of the

Lighting section a functional context

consists. In one embodiment, the longitudinal position of the illumination section is independent of the predetermined one

Longitudinal section length of the lighting section adjustable. Thus, for example, a user may first enter the

Set the illumination section length via the control unit and then the position of the lighting section in

Vary in the longitudinal direction. This can ensure that in the variation of the longitudinal position of the

Lighting section, the size of the illuminated by the bulbs of the lamp unit area not is changed. For example, the control unit may be set so that, given a variation of the longitudinal position of the illumination section, the same light intensity of the light emitted by the illumination means in the illumination section is always predetermined. In one

Embodiment, the longitudinal position of the

Lighting section can be adjusted manually via an actuator. For example, at the

Actuator a slider or can on the

Actuator buttons, such as plus, minus buttons as

Be provided control element, whereby a displacement of the longitudinal position of the lighting section can be manually easily realized.

In one embodiment, the control unit and the lighting unit are corresponding to each other

designed so that a certain intensity of illumination can be predetermined, with which the lamp unit emits light. For example, the illumination intensity may be a parameter that can be set in the control unit. For example, the

Lighting section length and the longitudinal position of a lighting section of the lamp unit can be changed independently of the predetermined illumination intensity. The specification of the illumination intensity can relate, for example, to the lighting unit as a whole, so that it is ensured that the

Lamp unit always the default

Lighting intensity is emitted via their bulbs. The specification of the illumination intensity can

For example, also done by everyone

Illuminant of the lamp unit, by the

Control unit is activated, a specific one

Lighting intensity is given, with which this light emits light. The illumination intensity, with the entire illuminant unit emits light, can be varied for example by a variation of the number of active, ie radiating bulbs, for example by a variation of the intensity, with the activated, ie radiating light bulbs

radiate. In particular, in one embodiment, the illumination intensity for each illuminant unit can be set separately so that each one

Light source unit is given a certain intensity with which this particular light emitting unit emits light. The embodiments of the invention, via which a variation of the illumination intensity is possible, allow a particularly good coordination of

Illuminance intensity with which all bulbs of the supply unit emit light, to the needs of the person in the room in which the supply unit

is arranged. For example, for a study of a patient, a higher illumination intensity

be specified as for a backlight

(General lighting), for example, for the use of a lighting unit as a reading light a certain, predetermined by the reading person and adjusted to their needs lighting intensity can be specified.

In one embodiment, the control unit is designed so that the number of activated by the control unit bulbs is adjustable. By way of example, this makes it possible to control the illumination intensity generated by the illuminant unit controlled by the control unit

is provided. For example, this can be a pleasant for a person in the room

Leuchterscheinungsbild the lighting unit of the

Be ensured supply unit.

In one embodiment, multiple illuminant units provided, which are arranged offset in at least one transverse direction to each other and / or light in each case

emit different solid angle ranges. As a result, a particularly good illumination of a room in which the supply unit is arranged can be ensured.

In particular, this may possibly illuminate a particularly large solid angle range in the room. Each bulb unit is forcibly so

trained to turn light into a specific one

Can radiate solid angle range. Therefore, in one

Embodiment by the offset in the transverse direction arrangement of a plurality of lighting units a larger

Solid angle area in the room to be illuminated.

For example, the solid angle ranges into which the respective illuminant units can emit light may overlap. In another exemplary embodiment, the illuminant units are arranged offset in the transverse direction with respect to one another such that their solid angle ranges do not overlap. In the provision of several

Lamp units is generally taken into account that not all of these light-emitting units must necessarily include each group of light sources, the

are arranged side by side and are independently controllable by the control unit. Such

Can be longitudinally controlled in one

Embodiment only for one or some of the

Be provided lighting means. In other

Embodiments can also all of

Lamp units of the supply units according to the longitudinal sections to be controlled.

In one embodiment, the supply unit comprises a plurality of lighting units each having a different light color. As a result, an even greater variation of the emission characteristic, by the supply unit is guaranteed, possible. For example, the

Illuminant units, each having a different light color, formed and on the

Supply unit may be arranged that their

Solid angle areas into which they can emit light overlap. This is a variation of the light color in the corresponding solid angle area in which the

Solid angle ranges of the lighting units with

overlap different light color, possible. In other embodiments, various

Solid angle regions may be provided, in each of which a different number of lighting units, each with a different light color overlap.

In one embodiment, multiple

Be provided with lighting units that perform different functions. For example, at least one of the lighting units can be designed as a reading light, at least one of the lighting units as

Background light for a general lighting, at least one of the lighting units as a signal light. In one embodiment, the illuminant units each have a different function, in one embodiment, at least some functions exert several illuminant units. It may be advantageous for the supply unit to have an optical element which is assigned to the lighting unit for predetermining the emission characteristic of the lighting unit. For example, anyone can

Each lighting unit to be assigned an optical element, for example, at least several

Lamp units each an optical element

be assigned. In other embodiments, an optical element may be associated with a plurality of illuminant units be. In particular, it may be advantageous that illuminant units, each in the same

Solid angle range can emit light, the same optical element is assigned. About the optical element or

a plurality of optical elements, the radiation characteristic of the emitted light from the light emitting units of the supply unit can be additionally influenced.

For example, a glare can be realized.

For example, through the optical element via

Diffraction and / or refraction the direction or the

Solid angle range, is emitted in the light from the light sources of the optical element associated lighting unit, be predetermined.

In one exemplary embodiment, the illuminant unit is arranged within a housing for protection against damage. For example, the housing may be transparent at a certain area. As a result, it can be specified that the illuminant unit emits light in the corresponding direction via the transparent region. Due to the arrangement of the lamp unit in the housing of the

Supply unit can be a particularly simple,

be ensured cost-effective and easy to keep clean design of the supply unit.

The supply unit may comprise an actuating device. In this case, the lamp of the supply unit may comprise an actuating device with operating elements, which is designed such that via the actuating device

Control parameters of the control unit for controlling the

Lamps of the lamp are manually adjustable.

For example, the actuator can so

be educated that electronically with the

Control unit is connectable or connected, for example via electrical lines or via a wireless Connection. About the actuator, a particularly simple manual control of

■ Be ensured lighting units of the supply unit, so that via the actuator, a person can easily adapt the emission characteristics of the lighting unit or the lighting means to their wishes.

Preferably, the actuator can be firmly connected to the supply unit. For example, the supply unit via an electrical cable, with the signals from the actuator to the

Supply unit can be communicated with the

Be connected actuator. The

Actuator is adapted to a patient and / or hospital staff adjusting the light of the supply unit to the environment of the patient

for example, to meet the needs of the

Patient or to the needs that involves examining the patient.

On the actuator are controls

intended. The controls can be configured for example as a button. The buttons can be mechanically formed, for example. The controls can, for example, in the form of icons on a touchpad

be realized. The person skilled in the art is conventional

Realization possibilities of corresponding controls known. In an advantageous embodiment, the actuating device and its associated

Control unit coordinated so that the

Actuator provides two different modes of actuation: In a first operating mode are

Basic settings in relation to the light of the

Supply unit vornehmbar, in the second

Actuation mode is a simple circuit for use the lamp of the supply unit feasible.

For example, different operating elements can be provided for the different operating modes.

For example, a different mode of operation of one and the same control element for the respective

Operating modes be provided. For example, in the first operating mode, the default is the maximum

Brightness of a lighting unit adjustable,

for example, about the maximum number of activatable lamps of the lamp unit and / or the maximum emission intensity of the light sources. For example, in the first actuation mode as the basic setting of the luminaire, a selection of the illuminant groups of a lamp can be made

Bulb unit take place in the second

Actuating mode can be activated. This can

For example, a position range can be selected, in which the activatable in the second actuation mode groups of bulbs are, so that the position from which light is emitted by the light emitting unit, when the light emitting unit is activated in the second actuation mode can be set. In one

For example, an operating element may be designed in such a way that, by a brief actuation,

for example, a brief mechanical pressing of the button, a switching, d. H. For example, a switching on and off in the second Betätigungsmodus-, is feasible,

whereas by a long operation of the control element, such as a press for at least three seconds, a change to the first operating mode is possible, then then in the first operating mode by briefly pressing the control adjustment parameters for the

Basic setting of the lamp can be set.

For example, the first operating mode for

Setting the basic settings of the luminaire in one Embodiment by again long pressing the

Control element are left in another

Embodiment by a non-actuation of

Control over a period of time, for example, over five seconds.

In an advantageous embodiment, the

Supply unit according to the invention on several lights. Each lamp is designed to illuminate an environment of a particular patient. In this

Embodiment, it may be advantageous that each lamp is assigned a separate control element, so that both the setting of the basic setting of the lamp and the operation of the lamp in the second

Actuation mode can be easily tuned to the desired environment of each patient. In such an embodiment, the supply unit has two

Control units, wherein each lamp a

certain control unit is assigned and one each

Actuator communicates with exactly one of the control units. In another such embodiment, the supply unit has only one control unit, wherein the actuating devices in each case with the

Control unit communicate that over each one

Actuation device via the control unit of

Supply unit, a setting or circuit of the respective actuator associated lamp is possible.

In an advantageous embodiment, the actuating device comprises as operating elements

Patient controls and personal controls. On the actuator, the controls are marked accordingly. For example, the

Patient controls and the personal controls too be provided at different locations on the actuator. For example, for the

Patient controls a handpiece may be provided which is connected by a cable to the supply unit and which the patient can hold in his hand, whereas the

Personnel controls are integrated in the housing of the supply unit. In another embodiment, each different handpieces for the

Patient controls and personal controls

be provided. The patient's handpiece can, for example, with the handle of a conventional, on the

Supply unit integrated nurse call systems coincide, the patient controls are provided on the handle of the nurse call systems. The distinction between patient controls and

Personnel controls is meaningful to the effect that the respective control elements can be assigned different control signals that the controls at

Transfer operation to the control unit. For example, it may be provided that only via the

Personnel controls an operation of the

Actuator in the above-described first actuation mode is possible with the basic settings of the lamp can be made. For example, the personal control elements and the patient operating elements can each be set so that they output certain predefined signals to the control unit when the actuating device is operated in the second operating mode for simple switching or operation of the light.

For example, via the patient controls a

Switching on and off of illuminant units and / or dimming of illuminant units, ie, for example, a change in the number of light-emitting bulbs of the illuminant units or a change in the Intensity, emit light with the bulbs of the lamp units, allows his. For example, personnel controls may be provided, the operation of which cause a particular circuit of the lamp.

For example, such a control signal can be assigned to a personal control element that illuminates the patient environment with maximum brightness, ie. H. that

All illuminant groups that illuminate the patient's environment are activated with all their illuminants. Such a personal control element can

For example, an optimal illumination of the

Allow patient environment for examination of the patient via actuation of the control element.

For example, another operator control element can be assigned to a night lighting state of the luminaire, so that via actuation of this operator control element

Illuminant groups of a lamp unit are activated with their bulbs that allow a discreet, non-disturbing backlight. By the

Provision of personal controls and

Patient controls can thus be ensured a particularly simple operation of the light of the supply unit, as the respective controls certain

Control signals for controlling the control unit can be assigned, so that by a few operating steps, possibly by simply pressing only one

Control a desired lighting situation

can be brought.

In an advantageous embodiment, several of the control elements are each assigned to the specification of control parameters to exactly one of the respective control element

Bulb unit formed. This has the advantage that on such a control exactly the

Illuminant unit can be controlled, which the can provide desired lighting situation.

For example, a lighting unit can be designed as a reading light, for example, a

Illuminant unit as a backlight for a

General lighting be formed, which is an indirect

Lighting of the room ensured. By an operating element is assigned to exactly one light emitting unit, just the desired in the particular situation

Illumination characteristic over the one

Illuminating unit be particularly easy to adjust.

In particular, it is possible that different

Operating elements are assigned to the same lamp unit. For example, an operating element can be assigned to exactly one lighting unit, with one being different

Operating element can be assigned to both this one illuminant unit and a further lamp unit. For example, an operating element of the reading light can be assigned, another operating element of a maximum possible illumination, for example one

Examination lighting, so that over the first

Control element only the reading light is adjustable, on the second control the reading light at the same time with all other lights. The assignment of

Controls to illuminant units allows a particularly simple and quick handling of the light of the supply unit.

Furthermore, in a further embodiment, a central actuating element for the specification of

Control parameters of the control unit may be provided. The central actuator is electronically connected to the control unit of the supply unit, so that from the central actuator control signals to the

Control unit can be sent. The central

Actuator can, for example, as a door switch be formed, at the front door and / or the

Bathroom door of a sickroom is installed. However, the central actuating element may, for example, also be an actuating element in a nurse's room, via which a central actuation of the supply unit and / or all supply units in one area of a

Hospital is possible. The central actuating element is thus spatially removed from the supply unit and not visually perceptible directly with the

Supply unit connected. By the central

Actuating element, for example, the light of

Supply unit be controlled so that they

General lighting ensures, for example, an indirect room lighting with a given intensity. The central actuating element can thus be used to predetermine which light source groups are activated by which light source unit. For example, by the central

Actuator also be a night lighting adjustable, d. H. an activation of lighting groups one

Light source unit ensures that a decent

To ensure the lighting of a room. For example, the lamp can be completely switched off via the central actuating element. For example, an examination illumination can be activated via the central actuating element, in which a high illumination of the room is ensured by means of a plurality of the light sources.

In one embodiment, the control unit, the central actuator and the actuator are coordinated so that the central

Actuator generally priority to the

Actuator outputs control signals. This means that, via the actuation of the central actuating element, the control unit controls the light of the supply unit in accordance with the control signal of the central actuating element controls, wherein the set by the actuator device settings are overwritten. In a further exemplary embodiment, the central actuating element is designed so that the control signal set by the central actuating element can be reset by a further actuation of the central actuating element, after which the setting parameters of the luminaire previously set via the actuating device are set again. A corresponding

Prioritization of the central actuator can bring the advantage that, for example, a

Night lighting or examination lighting via the central actuator is centrally adjustable, without the patient settings, over the

Actuator were set, this can prevent. A reset of the control signals of the central actuator by further pressing the

Actuator can bring the advantage that after the end of a certain situation that requires a certain illumination of the patient environment, the desired and previously set by the patient

Setting parameters of the lamp are set again.

In a further embodiment is at the

Supply unit an interface to a

Sister emergency call system provided, taking at the

Supply unit an emergency call button for triggering a

Sister emergency call is provided. In this advantageous embodiment, the emergency call button is directly on the

Supply unit provided. Preferably, the

Interface integrated with the nurse call system in the lamp, preferably in the actuator, so that a patient in the same actuator can find both the emergency call button and the controls for controlling the lamp. Preferably, one of the Operating elements of the actuating device designed as the emergency call button, wherein the emergency call button for outputting a control signal to the control unit for activating at least one of the lighting means as

Emergency luminaire unit formed illuminant unit of the lamp is formed. In this embodiment, the lamp comprises an emergency call center unit. By pressing the emergency call button, at least one light source of the emergency call light unit is activated. The described embodiment can bring several advantages:

For example, on the emergency call button a particular actuator such a light source of

Emergency lighting unit be activated, that the

Illuminant above the patient bed lights, from which the emergency button was pressed. Hospital staff can thus already entering a patient room

immediately recognize from which bed the emergency call was made. For example, a further advantage may be that the patient can recognize by the illumination of the illuminant of the emergency call center unit that he has made the nurse call and he with

Hospital staff can count.

Preferably, the supply unit comprises a

Interface for the inclusion of a central

Reassurance signal, the interface so

is formed, that via it a control signal to the control unit for activating a lighting means designed as a reassurance unit

Bulb unit of the lamp can be output. These

Embodiment, for example, bring the advantage that a patient on the central

Reassurance signal and thus on the activation of a light bulb of the tranquilizer unit can be displayed to hospital staff on the way to him is. In one embodiment, the

Tranquilizer unit and the

Emergency call center unit coincide. In one

Embodiment may be one of these two

Illuminant units, in one embodiment, both of these lamp units with another

Illuminant unit, coincide, It can on the emergency button a first group of bulbs this

common illuminant unit be activated, via the central reassurance signal a second

Light source group of the common lamp unit.

Thus, for example, the patient can recognize when he has made the nurse call and in turn recognize when the nurse call has been detected and staff is on the way to him. The feedback of a reaction to a

Sister emergency call via a central tranquilizer can exert a particularly calming effect on a patient and prevent panic. The realization of the

described control options via interfaces requires the professional implementation of the interfaces and communication of the interfaces with the control unit, for example via a correspondingly designed bus.
