Description

The invention relates to a switch unit with at least one base part.

Switch units are known in the art. These are used for switching on and off devices and devices, in particular in the form of light switches for switching on and off of light sources of a room lighting. It happens that conventional light switches upon entering a dark room are not immediately found, but rather cumbersome after this, before the room lighting can be turned on. As a temporary light, a light source is partially plugged into a socket near the door, so that you can possibly find the light switch by the low light that emits this auxiliary light. However, if such a temporary light is not provided, when entering dark rooms there is the problem that the light switch is badly located.

The present invention is therefore an object of the invention to solve this problem, that is, an easy findability of a switch unit, in particular a light switch, regardless of the lighting conditions in the room that is entered to allow.

The object is achieved by a switch unit according to claim 1, characterized in that at least one compared to the base member movably arranged switch presence detector unit is provided with presence detector and pressure and / or rotary switch functionality. Further developments of the invention are defined in the dependent claims.

This creates a combination of a presence or motion detector and a switch element as a switch presence detector unit, which combines the advantages of a presence or motion detector with the advantages of a switch. The switch presence detector unit is movably disposed opposite to the base portion of the switch unit to initiate a switching operation upon movement of the switch presence detector unit. The base part of the switch unit can be the power part of this, which is arranged and fixed, for example stationary in a room wall. Opposite this stationary part, the switch presence detector unit is movably arranged as an operating unit of the switch unit. The mobility can be allowed to a small extent, for example limited by a few mm, such as 1 to 2 mm. For triggering a switching operation of the switch presence detector unit, in particular at least one switch contact is provided. To reset the switch presence detector unit to its initial position prior to actuation, one or more return elements, such as spring elements, may be provided.

The switch presence detector unit may serve in addition to manually actuating the at least one switch contact for automatically switching on at least one light source of room lighting and / or one or more visual and / or acoustic signals for easy locating of the switch unit at least upon detecting the presence and / or emit the movement of a person in the detection area of the switch unit, whereby the person quickly finds the switch for switching on the light source even in dark rooms. The switch presence detector unit may comprise at least one infrared presence sensor element in which the thermal radiation is measured by persons or other heat sources, such as animals, moving in the detection area of a sensor element.

The presence or movement detector part is thus provided with a pressure and / or rotary switch functionality, which means that when a compressive force or rotational movement on the switch occupancy detector unit, this moves and thus as a conventional pressure switch, button or rotary switch Switching can trigger. The switch presence detector unit thus has a push-button, push-button or possibly rotary switch function. Upon entering a room can be done in a conventional manner actuation of the switch.

Advantageously, at least one lens unit is provided with at least one first illuminating means for illuminating the lens unit in order to provide backlighting of the actuatable part of the switch unit, ie the switch presence detector unit and to make it easy to find and / or to provide a status indication can indicate the operating state of the switch unit. Such a backlight thus represents an optical signal for finding the switch unit. For example, by backlighting with different colored light emitting diodes (LEDs), the functional state of the switch are displayed, for. B. by a red and a green LED. Advantageously, furthermore, at least one second light source can be provided, which radiates light in a space downwards in the direction of the floor and also represents an optical signal for locating the switch unit. However, it can also be provided a brightness-dependent and / or dependent on the presence of a presence or movement signal driving a room lighting and / or the second light source. Is in providing a presence signal or motion signal dependent control by the at least one Sensor element detects a movement, such as opening a room door and / or the presence of a person in the room, thereby the at least one second light source can be turned on, which is advantageously arranged in the lens unit or at least in the region of the lens unit or alternatively or additionally in a frame or frame part of the switch unit can be arranged.

Advantageously, at least one device is provided for adjusting one or more light intensities of the at least one second light source, wherein the selection from the set of set light intensities can be effected by a control unit. The values of the luminous intensities which can be selected via the control unit can be adjusted via adjusting devices, such as potentiometers. By setting the number of luminous intensity values, there is a set of selectable luminous intensity values, from which the control unit can be used depending on the desired mode in which the switch unit is working or should work, e.g. B. the mode of a nightlight or orientation light, make an appropriate choice. Furthermore, by means of an advantageously provided brightness sensor, the ambient brightness in the space surrounding the switch unit, which is to be illuminated by the room lighting, controlled by the control unit interacting with the switch unit, can be detected and compared with a predefinable or predetermined twilight threshold value. If the ambient brightness in the room falls below the predetermined twilight threshold, then the at least one second light source can be activated to emit light. If a movement or the presence of a person detected in the room, the at least one second light source from a first predetermined or predetermined light intensity or light intensity to a second predetermined or predetermined light intensity or light intensity, the z. B. higher than the first, change. The second intensity of light may also be less than or equal to the first intensity or intensity. Furthermore, upon detecting a movement or the presence of a person in the room, the at least one second light source can be switched off and the intended main room lighting can be switched on. Even without detection of a movement or presence of a person in the room, upon detection of decreasing ambient brightness in the surroundings of the switch unit, the at least one second light source can be switched on with a first light intensity or light intensity by the switch presence detector unit or the brightness sensor. As a result, the switch presence detector unit can be found without detecting a movement in the room with decreasing ambient brightness in the room without further notice upon entering the room by a person.

The lens unit is translucent or transparent to allow passage of light to detect the movement or presence of a person in the room.

Advantageously, the lens unit is provided with at least one conical arranged therein and / or conical reflector. By means of this, the light beams of the first luminous means, in particular of at least one light-emitting diode (LED), can be directed / directed into the frontal area of the lens unit or the lens, ie the area in front of the lens, so that no stray radiation into the remaining switch presence detectors Unit falls. Such an incidence of stray light would otherwise falsify a brightness measurement, which is advantageously provided for deciding to turn on the second light source. A light bundling in the direction of the at least one sensor element, which is provided for presence detection, is performed by the lens unit, through which the incident rays are focused to the sensor element.

For detecting the ambient light in the vicinity of the switch unit, the switch presence detector unit advantageously comprises, as already mentioned, at least one brightness sensor. In order to protect it against light from the light emitted by the at least one light source of the lens unit, the brightness sensor is advantageously protected or shaded or shaded within a housing of the switch presence detector unit by a device with respect to the light emitted or emitted by the at least one light source arranged. The device may be the reflector, wherein the brightness sensor is arranged on a side facing away from the at least one light source side of the reflector, so that the at least one brightness sensor hidden behind or below the reflector in a contact with the environment of the switch unit or brought Area can be arranged. The light emitted by the at least one light source can thereby essentially not be detected by the brightness sensor or the light emitted by the at least one light source is not detected by the brightness sensor as ambient light. For example, the at least one brightness sensor in the interior of the switch presence detector unit, in particular in the lens unit, arranged below the tapered surfaces of the reflector, ie on the side facing away from the reflector, and light-permeable only via light channels or in the arrangement region of the brightness sensors Lens unit with the outside of the switch unit, so the environment of this, in conjunction, so that stray light can be kept away from the brightness sensor. This can ensure that the actual ruling in the room Detected light conditions and the decision regarding the possible switching on the at least one second light source for making the switch element or the switch unit is based.

In addition to providing the at least one first luminous means for backlighting of the lens unit in the switch presence detector unit, in particular for displaying the operating state, the at least one second light source and at least one of these associated light exit opening may be provided, wherein the at least one second light source independent of the at least a first light source can be switched. The at least one second light source is advantageously designed as a so-called downlight, ie for illuminating a region of a room arranged below the switch unit in the installed state. Accordingly, the light exit opening is advantageously provided on the underside of the switch presence detector unit when arranging the switch unit in the installed position in a room, ie in particular when mounted on a room wall. In order to set or provide the targeted light emission only over a predetermined angular range, the at least one second light source can be arranged in a housing provided with the light exit opening. As a result, a light propagation in the switch presence detector unit can be avoided and the light propagation can be focused and shaped specifically. By providing a surrounding the second light source housing, which is also provided with a light exit opening to allow light to escape from this, on the one hand a scattering of light of the second light source in the interior of the switch presence detector unit and thus in the field Lens unit, which is backlit by the first bulb can be avoided. On the other hand, can be selectively adjusted by the housing and its light exit opening in conjunction with the light exit opening, which is provided in the switch presence detector unit, the light exit angle of the second light source.

The light exit opening on the housing surrounding the second light source can be covered by a transparent or translucent cap or cover, wherein the cover can also be colored in order to allow a colored light exit. The second light source is advantageously used as night and / or orientation light and is directed at arranging the switch unit in particular on a room wall down to avoid dazzling of people in the room.

Due to the independent switching of the first light source and the second light source optionally one or the other light source or both together emit light, z. B., when the first light only serves the status display. For the user, there is thus the freedom of choice as to whether he wishes to switch on the at least one first illuminant or to have it switched on or the at least one second light source or both. Accordingly, a driving device can be provided, via which the setting can be selected.

The at least one second light source is in particular likewise at least one light-emitting diode (LED). In particular, two LEDs are provided. The light color can be, for example, 3000 Kelvin. The at least one second light source may be disposed symmetrically with respect to the housing of the switch presence detector unit with respect to the central axis thereof to permit symmetrical light exit of the light cone emitted by the second light source with respect to the switch unit. Basically, however, an asymmetrical arrangement is possible.

The at least one first luminous means and / or the at least one second light source can be made dimmable and a device for dimming can be provided. Such a dimming, ie changing the brightness, z. B. by pressing or by turning a rotary switch or pressing a button, etc., also remotely controlled. This makes it possible, the respective light source or the respective light source first with only low brightness, ie a predetermined or predetermined first intensity or intensity to bring to light, for example, for permanent operation in detecting a loss of brightness, ie falling below a predetermined or predefinable twilight threshold, in the vicinity of the switch unit, such as at dawn and dusk. If a movement in the room and / or the presence of a person / heat source is detected by the at least one sensor element, the first light source and / or the second light source can emit or emit a different amount of light with a second presettable or predetermined light intensity or intensity, ie preferably shine brighter.

Upon detection of a presence and / or movement of a person in the room, the at least one first illuminant of the lens unit and / or the at least one second light source may remain switched on, that is to illuminate with the second illuminance or intensity. As soon as no movement and / or presence of a person in the room is detected any longer, the at least one first lighting means and / or the at least one second light source can be switched off again after a possible adjustable delay time, that is, again with the first light intensity or intensity to shine.

The room lighting of a room can be switched on by manually operating the switch presence detector unit. Further, it is possible, despite detecting the presence / presence of a person in the room by the at least one sensor element no actuation of the switch-presence detector unit, the room lighting automatically turn on. The switching on of the room lighting can thus be controlled manually by actuating the switch presence detector unit. Additionally or alternatively, due to the detection of a presence and / or movement signal by the at least one sensor element of the switch unit, the room lighting can be switched on automatically. In automatic as well as manually switching on the room lighting via the switch presence detector unit dimming the room lighting can be provided, in particular a rising with increasing time brightness of a corresponding light source of the room lighting. By switching on the room lighting, be it automatically or manually, the at least one second light source can be switched off. This can also be done automatically abruptly or under dimming.

The switch presence detector unit thus comprises on the one hand the at least one sensor element for presence and / or movement detection and on the other hand the at least one brightness sensor for detecting the ambient brightness in the surroundings of the switch unit, so that on the one hand the at least one second light source can be controlled and On the other hand, a dimming or switching on of the room lighting according to the detected signal of the at least one sensor element is made possible. The at least one second light source can permanently light with a comparatively low brightness, which preferably corresponds to the first light intensity, and serve as so-called night light, or with a greater brightness, which preferably corresponds to the second light intensity, and serve as a so-called orientation light , Furthermore, the at least one second light source of the switch presence detector unit can only be switched on if the at least one sensor element perceives a decreasing brightness in the room and / or a presence and / or movement of a person in the room, so that the room entering person can find the switch unit and press. If the switch element is not actuated, a signal for switching on the room lighting can be dispensed with further detection of presence and / or movement of the person in the room by the sensor element or by the evaluation of a control unit, the presence and / or motion signal detected at the sensor element is used to turn off the room lighting by the control unit and no longer detected presence signal and / or motion signal for switching off the room lighting. Switching off the room lighting can be done with a predefinable delay time.

The lens unit can be chosen differently with respect to its detection range, for example, a flattened or hemisphere lens can be used, which allows a semicircular detection range in the wall mounting of the switch unit. Other lens forms and lens optics, for example Fresnel lenses, may also be used.

Further advantageously, at least one rechargeable energy store for supplying the lighting means and / or light sources can be provided with power in the switch unit. The at least one rechargeable energy store can be designed as a modular unit and be provided with at least one connecting device for insertion into the switch unit and connecting to the first light source and / or the second light source. By arranging the rechargeable energy storage, in particular accumulators, as a module unit in the switch unit a simple insertion and removal is possible. Advantageously, this module unit is arranged in the housing of the switch unit in a frame element in order to protect the at least one rechargeable energy store, which is arranged on a corresponding board against mechanical attacks and spatially separate from the or the other electronic components of the switch unit, wherein the module unit comprising the at least one rechargeable energy store is advantageously arranged between the front-side switch presence detector unit cover, which comprises the at least one lens unit, and electronic components for actuating the switch unit.

By the modular units of the switch unit spring elements can also extend, which serve the resilient provision of the switch presence detector unit in training as a button.

1 shows a plan view of a switch unit 1 , This includes a switch presence detector unit 10 , This is in 2 outlined in detail. It can be angular in plan, as in 1 indicated, or be round. Other shapes are possible. The switch presence detector unit 10 is like 1 and also 3 can be removed in a frame 11 the switch unit 1 inserted. It protrudes over its outer surface 19 addition, as the side view of the switch unit 1 in 3 can be removed. When installing the switch unit 1 in an in 3 indicated room wall W can the frame 11 are locked in a metal frame and a arranged in the room wall W part 80 the switch unit 1 in a tin 81 be housed in the room wall W and a housing 17 exhibit. The part 80 includes the power section of the switch unit, thus the circuit of the switch unit 1 , and a control unit 8th located in the switch presence detector unit 10 is arranged. The part 80 is fixedly arranged in the wall W, while the frame 11 on this rests and the switch presence detector unit 10 at least in part out of this or this one (see 3 ) and movable towards the part 80 or the housing 17 is. By providing this mobility, the switch presence detector unit receives 10 its switch functionality, thereby becomes the switch. To trigger a switching of a light source of a room lighting 9 At least one contact switch on the movable switch Presence detector unit 10 be provided as the in 3 indicated dome switch 130 , When moving, especially moving, the switch presence detector unit 10 this comes with the contact switches 130 in contact, actuates these, and the contact switches solve a switching operation in the at least one light source of the room lighting 9 out. The control unit 8th to control the switching operations is via a connection 18 with at least one light source of the room lighting 9 connected. The connection 18 may be in the form of a cable and / or as a radio link or otherwise, and is in 3 indicated by a dashed line.

The switch presence detector unit 10 has a lens unit for motion / presence detection 13 on. This is from a first cover 12 and a second cover member 14 Flanked on two sides, ie between the two cover elements 12 . 14 arranged, like 1 can be seen. However, the arrangement can also be varied. The lens unit 13 is here exemplarily elongated rectangular and narrower than the two cover elements 12 . 14 , In order to allow a light or radiation passage, the lens unit 13 transparent, in particular translucent or opaque, may also be transparent. The two cover elements 12 . 14 are not translucent. The lens unit 13 is with a reflector element 3 Mistake. At its center is a sensor element 4 arranged. To a radiation entrance in the direction of the sensor element 4 to enable is the lens unit 13 especially permeable to infrared rays when the sensor element 4 designed to detect the presence of a person in a room via infrared radiation measurement. The reflector element 3 is conical in the direction of the sensor element 4 designed to taper.

The lens unit 13 comprises one or more lenses, may be provided in particular with Fresnel lenses. The provision of Fresnel lenses is particularly suitable because with a comparatively flat design short focal lengths and a high light or radiation incidence yield are possible. The sensor element 4 , in particular infrared sensor element, is inside the switch presence detector unit 10 added. The sensor element 4 captures presence signals and motion signals. For detecting the brightness in the environment of the switch unit 1 are exemplary two brightness sensors 5 intended. These are how 1 can be taken on two opposite sides 110 . 111 inside the lens unit 13 below the tapered surfaces of the reflector element 3 arranged. In the in 2 shown cross-sectional view are two of the brightness sensors 5 indicated. These are due to their arrangement below the conical surfaces of the reflector element 3 against scattered radiation from LEDs 6 in the area of the lens unit 13 are arranged, protected, as the reflector element 3 that of the light emitting diodes 6 outgoing rays of light only in the frontal area 112 the lens unit 13 directs. An incidence of stray light from the LEDs to the brightness sensors 5 can be avoided, it is only a lateral incidence of light on the brightness sensors 5 provided by the arrows P1 and P2 in 2 is indicated.

Inside the switch presence detector unit 10 in the area of the lens unit 13 is the number of LEDs 6 arranged as the first light source of the switch presence detector unit. These are as in 1 and 2 indicated on a circuit board 7 and approximately parallel or perpendicular to the outer surface 15 the lens unit 13 on a side wall 16 arranged by this. The light-emitting diodes 6 are essentially flat, so they are only slightly inside 114 the lens unit 13 protrude into it. The light-emitting diodes 6 can z. B. to indicate the operating status and be designed as red and green LEDs. Like the sketchy cross-sectional view of the switch presence detector unit 10 in 2 can be taken, are the brightness sensors 5 , as already mentioned, by the reflector element 3 from the LEDs 6 sealed off, so that the brightness sensors 5 be shadowed by this, thus a decoupling from the light emitting diodes 6 emitted light and scattered light is thereby provided.

The function and operation of the switch unit 1 can via the control unit 8th to be controlled, in particular in the switch presence detector unit 10 and here exemplarily in the housing 17 the switch unit 1 is arranged, but may also be arranged outside of this, in particular at a central location of the room or a building and / or in the region of a light source of the room lighting 9 , About the control unit 8th is a switching on and off of the room lighting 9 of the room and / or individual light sources of the room lighting 9 possible. The room lighting 9 is in 3 merely indicated and may include a number of light sources, commonly removed from the switch unit 1 arranged at one or more locations of a room and with the switch unit 1 about the connection 18 are connected.

In addition to the first light source in the form of light emitting diodes 6 here is a second light source 50 intended. The control unit 8th can be the second light source 50 to the effect that this in the idle mode of the switch unit 1 lights with a low brightness, so only emits a small amount of light, preferably one corresponds to the first predetermined or predetermined light intensity or intensity, thus only serves as a night light, over which the switch unit can be found and operated by a person in the dark or on a person can orient themselves in a room at least roughly. Another example of use is as a night light for nursery rooms, so that the or the in-room children are not exposed to complete darkness and thus provided by the provision of the night light quiet. Will the switch presence detector unit 10 the switch unit 1 actuated, thereby becomes the room lighting 9 turned on and the second light source 50 switched off. The operation of the switch presence detector unit 10 can be done in the usual way, being at the bottom 20 the contact switches, as exemplified in 3 indicated dome switch 130 are arranged, which respond when pressure is applied to these and a switching operation for switching on and / or off the at least one light source of the room lighting 9 trigger. The contact or dome switch 130 can also be designed so that when they operate an otherwise usual at switches noise, in particular cracking noise, is delivered. The switch presence detector unit 10 can also be stored tiltable and accordingly the contact switches are arranged so that when tilting a switching operation can be triggered. Furthermore, it is also a forming of the switching presence detector unit 10 with a rotational mobility possible, wherein the one or more contact switch in this case to trigger in the rotating movement of the switch presence detector unit 10 can be trained.

Alternatively or additionally, by the sensor element 4 the presence of a person in the room and automatically detects the room lighting 9 be turned on. For example, a switch-on is initially possible with a low brightness. Will the actuation of the switch presence detector unit 10 After that, the room lighting can be detected 9 fully switched on, so the brightness can be increased accordingly, thus the light output through the room lighting 9 , If there is no further actuation of the switch presence detector unit 10 , if necessary, the low light output through the room lighting 9 be maintained.

Furthermore, it is possible that after a predetermined or predetermined period of time, the room lighting 9 is completely turned on when the sensor element 4 detected further movement or presence of at least one person in the room and also the brightness sensors 5 detect a falling below a predetermined twilight threshold or a brightness threshold. Even without pressing the switch presence detector unit 10 can thus over the room lighting 9 fully switched on, a specifiable light intensity or amount of light thereby from the room lighting 9 be delivered. If no further movement in the room or also no presence of at least one person more in the room determined, after a predetermined period of time for a persistence of the room lighting can continuously or gradually 9 be reduced amount of light emitted, possibly down to zero, so until the room lighting 9 is completely switched off. In turn, it can only be that of the second light source 50 amount of light left to a night light for finding the switch unit 1 or the switch presence detector unit 10 provided.

The second light source 50 can be made dimmable to light them with different brightness, for example, for standby operation, as already mentioned above, only with a very low brightness, upon detecting the presence of a person in the detection area with a higher or higher brightness finding the switch unit 1 for the person to facilitate or at least provide an orientation light for them, provided the room lighting 9 is not switched on or should be. The light intensity, in particular two different light intensities, the second light source 50 is / are application-specific (free) selectable. The first light intensity preferably leads to a less bright illumination of the second light source than the second light intensity, so that a night light can be created with the first light intensity and an orientation light with the second light intensity. Furthermore, the follow-up times for both a night and an orientation light can be selected application-specific (free).

As embodiments, a semi-automatic mode and a full-automatic mode of the switch unit will be described below 1 or control unit 8th described in more detail by this. In semi-automatic mode, the second light source automatically turns off when a certain brightness value is undershot 50 turned on as a downlight with a first light intensity. Upon detection of a movement or the presence of a person in the room or detection area of the switch presence detector unit 10 becomes the second light source 50 controlled to emit light of a second intensity. After expiry of a predefinable or predetermined follow-up time, the second light source illuminates 50 again with the first light intensity (eg as night light). Will during the follow-up period, in which the second light source 50 Emits light of the second intensity by manually operating the switch unit 1 the room lighting 9 turned on, then becomes the second light source 50 completely switched off. Once the room lighting 9 is switched off, either by pressing the switch unit 1 or automatically after the overrun time has elapsed, the second light source lights up 50 again with the first light intensity (eg as night light).

In fully automatic mode, the second light source automatically turns off when a certain brightness value is undershot 50 switched on with the first light intensity. Upon detection of a movement or the presence of a person in the room or detection area of the switch presence detector unit 10 becomes the second light source 50 switched off and the room lighting 9 switched on. Will no movement or presence of a person in the room or detection area of the switch presence detector unit 10 If more is detected, the second light source lights up after a predefinable or predefined delay time has elapsed 50 again with the first light intensity. Is by manually pressing the switch unit 1 the room lighting 9 although a movement or the presence of a person in the room or detection area of the switch presence detector unit 10 is detected, then the second light source 50 switched on with the second light intensity. Thereafter, no movement or presence of a person in the room or detection area of the switch presence detector unit 10 more detected, the second light source is lit. 50 after expiry of the predefinable or predetermined follow-up time automatically back to the first light level.

In both half and full auto modes, when the room lighting is on 9 when the switch unit is operated again 1 (especially in training as a button) the room lighting 9 turned off and the second light source 50 switched on again as orientation light. The latter can be switched back to the first light intensity or completely switched off after expiry of a follow-up time or automatically again with respect to its light intensity.

Furthermore, to illuminate, for example, a narrow, long room, such as a corridor or corridor, also several switch units 1 be connected via a bidirectional remote line. This allows a master / slave operation, the settings with regard to the brightness value or the light intensity and the delay times at the respective individual switch unit 1 can be made. That means that on every single device or each switch unit 1 individual values can be set, which differ from the values of the other switch unit (s) 1 or the settings of the values at some or even all switch units 1 can be the same. So is a switch unit 1 set to slave mode, so apply to this switch unit 1 however, the parameters set at this and not the parameters set on the switch unit which is set to the master mode. A synchronization of the switch units 1 is thus only manually by adjusting the respective values or parameters of the individual switch units 1 possible to each other. The main or room lighting 9 is to the master switch unit 1 connected. On the remote line is that of a slave switch unit 1 signal generated by a detected movement / presence or by manually operating a switch unit 1 generated signal is passed to the master switch unit. This in turn evaluates this signal and outputs the resulting information about the switching of the second light source 50 to the slave switch unit (s). The detection of the movement or the manual operation of the switch unit 1 However, it can also be done on the master switch unit, which then sends a corresponding signal to switch the second light source 50 transmitted to the slave switch unit (s). By the signals of the master switch unit is then according to the settings of the respective slave switch unit, the luminous intensity or intensity of the second light source 50 controlled, so this depending on the direction of the master-switch unit in the mode of a night (first light intensity) or orientation light (second light intensity), or the second light source 50 switched off when the master switch unit is the main or room lighting 9 turns. Is the main or room lighting 9 is switched on, by manually pressing any switch unit 1 sent via the remote line, a corresponding signal to the master switch unit, which in turn the main or room lighting 9 turns off, the second light source 50 with the first light intensity, wherein the signal for switching on the second light source 50 transmitted to the slave switch unit (s) at the first level of light through the remote line.
