Description

Improved room light

The present invention relates to an improved room lamp, in particular a

Room lamp in which the brightness, color temperature, the color of the light output, the angle of the light output and the illuminated area are freely adjustable during operation.

In the prior art lamps are known which are dimmable and the color temperature and the color of the light output are adjustable. The adjustment of the light color and the color temperature can be carried out by means of a remote control. There are also so-called spots known whose illumination angle can be adjusted after installation.

Lamps with a variable color temperature and / or a variable color of the light output require a relatively large amount of space, so that they are unsuitable for modern lighting. Spots have the disadvantage that the angle of the light output can be adjusted only by a mechanical adjustment of the spot. There are also LED-based lights known, but still require a relatively large amount of space.

EP 1 434 277 A1 relates to a beam condensing element which is connected to a light source and a luminous surface with wedge-like regions.

EP 2 518 398 A2 proposes adjustable and pivotable LED groups.

The invention has as its object to provide a room lamp, which overcomes the aforementioned disadvantages of the prior art.

The object of the invention is achieved by a room lamp according to claim 1 or 2 and a method according to claim 15.

A room lamp according to the invention, which is designed to illuminate a room controllably at different angles, has a plurality of luminous elements and a first luminous element with a plurality of light-deflecting devices, on each of which a luminous element is arranged, each luminous element emitting light into a light-deflecting device. At least one light-directing device comprises a collimating region, in which the light rays of the luminous element, which is arranged on the light-directing device, are parallelized, and at least one prism region, each of which forms part of the light-emitting device

redirects parallelized light rays. Through the at least one prism area can very space-saving luminaire and thus a space-saving room lamp can be achieved. Different light-guiding devices can have different prism areas, as a result of which a luminous element can emit light at different angles. By switching on, dimming and switching off light-emitting elements which are arranged on predetermined light-deflecting devices, the angle and / or the range of the light output can be varied during operation. The lighting elements can be arranged in the light-guiding device. This results in a very space-saving room lamp together with the light-deflecting device with the integrated collimation area and prism area.

A prism area of a light-directing device may have an area inclined to the light beams that are parallelized by the collimation area. The inclined portion of a part of the light directing means may reflect the parallelized light. This is the case when the angle of the inclined area is greater than the critical angle. The critical angle may be the critical angle of Snell's law of refraction. The light rays run in a medium that is optically denser than air. The light-guiding devices may be made of a plastic, for example of a polymer plastic,

for example PMMA.

The inclined portion of a part of the light-deflecting devices may break the parallelized light. The latter may be the case if the angle of the collimation area with respect to the parallelized light beams is lower than the critical angle. Through this

Measures, the required space can be reduced.

A plurality of first light directing means outputs the light coming from a first one

A plurality of second light-directing devices emit the light emitted from a second light-emitting element into a second light-directing device at a second angular range, and an optional plurality of third light-directing devices emits the light. which is emitted from a third light-emitting element into a third light-directing device, at a third angle range. The room lamp according to the invention can emit light at different angles in a room, so that desired effects for a user arise and the lighting can be optimized depending on the current use. The light output of the room light can vary depending on the current use. The light output of the room lamp, lighting can create a dining table during the meal or lighting a part of a room, for example when watching TV. The room lamp according to the invention can have any number of light-directing devices which emit the light each in a predetermined angular range. The

Angle ranges of the light output of the room lamp may at least partially overlap or differ from each other.

The inclined regions of a light-directing device can each have a different angle with respect to an imaginary plane. This ensures that a light deflecting device can emit light over a larger angular range, thereby increasing the visual comfort for a user of the room lamp.

The prism areas may extend over a plurality of light-deflecting devices, and the inclined area may have the same angle with respect to an imaginary lighting plane along the prism area. Consequently, a majority

Lichtlenkeinrichtungen light in a predetermined angular range, whereby the

Homogeneity of the light output and the spatial angle spectrum can be increased in an axis perpendicular to the illumination plane.

A plurality of prism areas and / or a plurality of light-deflecting devices may be arranged concentrically. This will increase the comfort of light output for one

User again increased.

A plurality of light-deflecting devices may be arranged in a line. Thereby, a room can be illuminated by the room lamp in a manner that is reproducible to a user.

The inclined regions of the prism regions of a light-directing device can be inclined in the same direction, in particular the same spatial direction. It can thereby be ensured that an angle range of a light-directing device is illuminated as homogeneously as possible since a plurality of light sources are present which emit light at a similar angle.

The first luminous element with the plurality of light-deflecting devices may be formed in one piece. Thereby, the luminous body can be manufactured by an efficient manufacturing method such as an injection molding method, an extrusion die or the like. The lighting element may be an LED. The light-emitting element can be arranged at least partially in the light-directing device. Through each of these

Measures can be created a particularly space-saving room lamp. Luminous elements of different colors can be arranged in light-guiding devices whose inclined areas each have the same angle. Thereby can

Angle segments are illuminated with different colors.

The first luminous element can emit light downwards in use, the room luminaire furthermore having a second luminous element which emits light upwards. The room lamp can be attached to the ceiling by means of a cable. The room lamp can be attached in any other way. A diffuser may be arranged on the first luminous element and / or on the second luminous element. As a result, a homogeneous light output is achieved in the room.

The angle of a cylinder-conical region between the collimation region and the prism region may be inclined with respect to the parallelized light such that the farther it is from the light source, the narrower the cylinder-conical region is. This can ensure that the luminous bodies can be produced by means of an injection molding or an extrusion process.

Each light-directing device can have one to five, preferably two to four, more preferably three, prism areas. Two to four prism areas are a compromise between overall height and losses due to rounded edges.

The room lamp may further comprise an orientation determining device, which is designed to determine an orientation of the room lamp. The room light may further comprise a transmitting device and / or receiving device, which is designed to receive a, preferably wireless, signal. The

Receiving means may drive the lighting elements in response to the received signal. By orientation determination device, the orientation of the room lamp can be determined in relation to the orientation of an electronic control unit. The electronic keypad may be a mobile electronic device such as a telephone, a smart phone, a tablet computer, a portable computer, or the like. The mobile electronic device may have a built-in compass. The Orientierungsermittlungseinrichtung the room lamp can also be a compass. The orientation determination device of the room lamp can alternatively or additionally determine the position of the operating device on the basis of the received signal, for example the direction, the field strength or the like. This can especially when a plurality of communicating room lights are performed.

The position of the operating device can be determined by means of radio signal location. It is also possible to use the signal field strength as an additional source of information, if it is received by several, optionally mutually communicating, lamps, for example by means of triangulation.

The HMI device may display a representation of the room to be illuminated or a virtual area that would correspond to an ideal room. In one embodiment, the room light can transmit an orientation to the operating device. The operator device may change the orientation of the representation of the room to be illuminated in response to the transmitted orientation, for example, rotate or display another representation.

The invention also discloses a room lamp with a

Orientation determination device, which is adapted to an orientation of the

Determine room light, and a receiving device, which is adapted to receive a signal, wherein the receiving means drives the light emitting elements in response to the received signal. The room light can be developed as previously described.

The object of the invention is also achieved by a method for controlling the light output of a room lamp with the following steps. The size and / or the color and / or the brightness and / or at least one area to be illuminated in the room and / or the angle of the light output of the room lamp is controlled by means of a gesture on a touch-sensitive screen of an operating device, for example a portable electronic device. The orientation of the portable electronic device is detected. The size and / or the color and / or the brightness of the area to be illuminated and the orientation of the portable electronic device is attached to the

Room light sent. The orientation may alternatively or additionally from the

Room light to be transferred to the HMI device. The assignee of the present invention reserves the right to separately claim protection for these aspects.

The room light may drive the light elements for at least one area in response to the received size and / or the received color and / or the received brightness. The at least one area to be illuminated by the room lamp can be fixed on the touch-sensitive screen by means of a drawing movement on a partial area corresponding to the area to be illuminated. The brightness of at least one partial area to be illuminated by the room light can be increased the longer a corresponding partial area of the touch-sensitive screen is touched. The brightness of at least one sub-area to be illuminated by the room light can be increased the faster it is painted over a corresponding sub-area of the touch-sensitive screen. The brightness of at least one partial area to be illuminated can be increased, the more frequently a corresponding partial area of the sensitive area

Screen is touched and / or the more frequently over a corresponding portion of the touch-sensitive screen deleted and / or the more pressed on a sub-area.

The room light can be used for downward lighting and / or for upward lighting in response to a gesture such as a click or

Double-click on an icon on the touch-sensitive screen to full

Light output to be switched. The room light can be for the downward

Lighting and / or for the upward lighting in response to a double click on a symbol on the touch-sensitive screen to full

Light output to be switched. The brightness of the downwardly directed illumination and / or the brightness of the upward illumination may be varied in response to a shift of a symbol on the touch screen, for example by uniformly increasing or decreasing the brightness of all the light elements. The brightness of the down-facing illumination and / or the upward-facing illumination in response to a swipe gesture can be varied with one finger or with two fingers on the touch-sensitive screen.

The brightness of a partial area to be illuminated is reduced after a deletion symbol has been touched on the touch-sensitive screen and a character movement has been carried out over a corresponding partial area of the touch-sensitive screen which corresponds to the partial area to be illuminated. The brightness of a partial area to be illuminated can be reduced after a deletion symbol has been touched on the touch-sensitive screen, the brightness being reduced the more, the longer a corresponding partial area of the latter subsequently becomes

touch-sensitive screen is touched. The brightness of the sub-area to be illuminated is reduced after a deletion symbol on the touch-sensitive area Screen is touched, wherein the brightness of the sub-area to be illuminated is the more reduced the faster then over a corresponding sub-area corresponding to the area to be illuminated, the touch-sensitive screen is deleted. The brightness of a partial area to be illuminated can be reduced after a deletion symbol has been touched on the touch-sensitive screen, the more frequently the brightness of the partial area to be illuminated is subsequently touched and / or deleted over a corresponding partial area of the touch-sensitive screen ,

The downward illumination and / or the upward illumination may be turned off in response to a touch and / or a double-click on an icon on the touch-sensitive screen.

The color temperature of the light output of the room lamp can be selected by marking a point on a two-dimensional representation of possible color temperatures. The color of the light output of at least a portion of the room light can be selected by marking a point on a two-dimensional representation of possible colors. The light output of the room light can be changed in response to an external event. The external event may be an electronic message, such as an SMS, an e-mail, or a warning message from a warning service. The light output of the room light can be changed in response to the time.

For example, the light output in response to a sunrise, a

Sunset and / or be changed as alarm and / or sleep function. The light output of the room light can be changed in response to an external parameter, such as light, sound, the detection of persons, for example by means of optical sensors or the like.

The method may include the step of rotating a representation of the area to be illuminated in response to orientation and / or change in the orientation of the portable electronic device and / or the room light. The representation of the area to be illuminated may be a representation of the space and / or a virtual space and / or an ideal space.

With reference to FIGS. 1 to 6, a first luminous body with a plurality of light-deflecting devices 102, 104, 106, 108, 110, 112, 114 is described. As can be seen in FIGS. 1 to 3, six first light-directing devices 1 14 are arranged in a first inner circle. The first light-deflecting devices 1 14 include a recess 120 in FIG a light-emitting diode 122 is arranged, as can be seen in Figures 4 to 6. The light of the light emitting diode 122 enters the first light guide, the operation of which will be hereinafter referred to, and occurs at the three priming areas 1 14a, 1 14b, 1 14c by being deflected at the inclined faces of the prism areas

relatively steep angle in a first angular range of about -10 ° to about 20 °. The light emerging from the first light-directing device 1 14 is scattered by a diffuser 150 for homogenization. Furthermore, unwanted light rays that arise, for example, due to an optical Inperfektion of the components used, scattered and attenuated. To simplify the illustration, the scattering by the diffuser 150 is not shown in the figures.

A plurality of second light-deflecting devices 1 12 are arranged concentrically around the plurality of first light-deflecting devices 1 14. The light emerges from the inclined surfaces of the prism regions 12a, 12b, 12c in a second angular range of approximately 0 ° to approximately 40 ° and is thus more deflected than the light output of the first light-directing devices 14. The mode of operation of the second light-directing devices 1 12 will be described in more detail below with reference to FIG.

A plurality of third light-directing means 1 10 is arranged concentrically around the plurality of second light-directing means 1 12. The light that passes through a light emitting diode in the

Recess 120 is reflected at the inclined surfaces of the prism-like portions 1 10a, 1 10b, 1 10c and exits the prism areas in a third

Angle range, which is shallower than the second angle range, and is scattered in the diffuser 150 and homogenized. The third angle range is about 10 ° to about 60 °. The third angular range is directed in a different direction than the first angular range, the second angular range, and the fourth angular range described below.

A plurality of fourth light-directing devices 108 are arranged concentrically around the plurality of third light-directing devices 110. The light of a light emitting diode 122 enters the fourth light guide body 108 via the recess 120, and is reflected on the inclined surfaces of the prism areas 108a, 108b, 108c before leaving the prism area at a fourth angle range of about 20 ° to about 70 °. emerges and is scattered and homogenized by the diffuser 150.

A plurality of fifth light-directing devices 106 are arranged concentrically around the plurality of fourth light-directing devices 108. The light of a light emitting diode comes over the

Recess 120 in the fifth light guide 106 and is at the inclined Areas of the prism areas 106a, 106b, 106c reflected before it from the

Prism areas under a fifth angle range of about 30 ° to about 80 °, which is shallower than the fourth angular range, emerges and then scattered in the diffuser and homogenized.

A plurality of sixth light-deflecting devices 104 are arranged concentrically around the plurality of fifth light-deflecting devices 106. The light of a light-emitting diode 122 enters the sixth light-deflecting device 104 via the recess 120 and is reflected on the inclined surfaces of the prism areas 104a, 104b, 104c before it emerges from the

Prism areas at a sixth angle range of about 35 ° to about 85 ° and then homogenized and scattered in the diffuser.

A plurality of seventh light-deflecting devices 102 are arranged concentrically around the plurality of sixth light-deflecting devices 104. The light of a light emitting diode comes over the

Recess 120 in the seventh light-deflecting device 102 and is reflected on inclined surfaces of the prism portions 102a, 102b, 102c, before it from the prism areas at a seventh angular range of about 40 ° to about 90 °, the shallower than the sixth angle range, from the 7th light deflector 102 before entering the diffuser 150 for scattering and homogenization. The third, fifth and sixth

Angles are opposite to the first, second, fourth and seventh angular ranges.

With reference to FIG. 3, it can be seen that the prism areas of the first light-directing device 1 14, the second light-directing device 12, the third

Lichtlenkeinrichtung 1 10, the fourth light-deflecting device 108, the fifth

Light guide 106, the sixth light guide 104 and the seventh

Light deflector 102 are arranged concentrically circumferentially. The prism areas of the light directors 102-114 are formed in the manner of Fresnel lenses.

FIG. 2 shows in perspective collimating regions 124 of the light-directing devices 102 - 1. At the end of the conical collimation region 124 is a recess 120, in which a light-emitting diode is arranged.

The collimating portion 124 will be described with reference to FIG

Sectional view described in more detail. In Kollimationsbereich is the

Recess 120, in which the light emitting diode 122 is arranged. The collimating region 124 parallelizes at its conical surfaces the light of the light emitting diode in substantially three exemplary radiation bundles as a frequency distribution 126, 128, 130. The

Collimating region 124 and the light directing devices 102-1 14 may be formed of a transparent plastic, such as PMMA.

With reference to Figure 5, the operation of the first light-guiding devices 1 14 and the second light-guiding devices 1 12 is exemplified by the second

Lichtlenkeinrichtungen 1 12 explained. The light rays parallelized by the collimation area 124 impinge on the inclined surfaces of the three prism areas 112a, 112b, 112c and are therefrom broken away by the solder, since the inclined surfaces of the

Prism areas 1 12a, 1 12b, 1 12c opposite the parallelized light beams are below the critical angle.

Referring to FIG. 6, the operation of the third light guide 1 10, the fourth light guide 108, the fifth light guide 106, the sixth light guide 104, and the seventh light guide 102 will be explained using the example of the sixth light guide 104. The parallelized light beams impinge on the inclined surfaces of the prism areas 104a, 104b, 104c at an angle greater than the critical angle. Thus, the beams 130, 132, 134 are reflected on the inclined surfaces of the prism portions 104a, 104b, 104c and exit the sixth light deflecting means on the surfaces opposite to the inclined surfaces. It is understood that the inclined surfaces may be coated to reduce the losses, for example by means of reflective coatings. The inclined surfaces may have reflectors.

As can be seen in Figures 5 and 6, extends between the conical Kollimationsbereich, which tapers in the direction of recess 120, and the

Prism areas 104a, 104b, 104c, 112a, 112b, 112c, a cylinder cone tapering towards prism areas 104a, 104b, 104c, 112a, 112b, 112c. This

Cylinder cone 126 is required so that the luminous body 100 by means of a

Injection molding or an extrusion die can be produced.

The inclination of the cylinder cone may be from about 1 ° to about 2 °. It can thereby be achieved that the deviation from an ideal cylinder has only a small influence on the quality of the light output. In all the light-guiding devices, the inclined surfaces of the prism areas may have different inclinations with respect to each other so as to enable each

Lichtlenkeinrichtung emits light under a wider angle spectrum.

Reference is made to FIGS. 7 to 10, which show a second luminous element 200. The second luminous element 200 comprises a light-guiding body 208, which has a convex curvature at a first region 208a when viewed from the outside, and is planar at a second region 208b, which lies opposite the first region 208a. In addition to the first region 208a and the second region 208b, there is a third region 208c, which, viewed from the outside, has a convex curvature. Opposite the third region 208c, a light-emitting diode 204 is arranged in a concave recess. Below the second region 208b, a first reflective surface 210 is disposed. At the third region 208c, a second reflective surface 212 is disposed. The third area 208c is disposed adjacent to the first area 208a. The expression besides also includes that the first region 208a and the second region 208c need not necessarily touch each other. In the embodiment illustrated in FIGS. 7 to 10, the third region 208c is below the first region 208a. Relative to the second region 208b, the curvature of the first region 208a is in an angular range between about -5 ° to about -30 °. Opposite the second region 208b, the curvature of the third region 208c is in an angular range between about 30 ° to about 60 °.

FIGS. 8 to 10 show that the light beams 214, 216, 218 emerging from the light-emitting diode are reflected in the first area 208a and the second area 208b until the exit angle of the light beams is below the critical angle and the light beams are below a flat angle Angle from the light guide 208 exit. As a result, a flat indirect lighting, such as the ceiling can be achieved.

In FIG. 9, it can be seen that light rays 216 emerging from the light emitting diode 204 at an angle near the optical axis are reflected by the second reflective surface 212 at the third region 208c of the light guide body 208 and thereby into comparatively flat rays within the light source Lichtleitkörper 208 are converted, which are then reflected by the light guide body 208 and the reflective surface 210 until they emerge from the light guide body 208 at the first region 208a at a shallow angle, which is lower than the critical angle. The light is forwarded in Lichtleitköper 208 as in a glass fiber due to the total reflection. Once the angle is low enough, it exits the light guide body at the bulge 208a at the first region.

The light guide body 208 may be formed substantially annular and the plurality of second light-emitting diodes 204 may be annular and / or formed in segments for delimiting the light regions on the second light-emitting body.

Reference is made to FIG. 11, which shows an arrangement of first light-emitting diodes 122. The first light-emitting diodes 122 are arranged concentrically. Other patterns are possible, such as hexagonal. The light-emitting diodes 122 can be arranged in the recess 120 of the light-directing devices 102-1. The LEDs are arranged concentrically in several circles. A circle of an arrangement of concentrically arranged light-emitting diodes 122 has light-emitting diodes which are assigned to exactly one type of light-directing devices 102-1 14 and are arranged in the recess thereof. Within a circle light emitting diodes of different colors and / or different

Be arranged color temperature. The arrangement of the LEDs of different types can be done alternately or by sector.

Reference is made to FIG. 12, which has an arrangement of second light-emitting diodes 204 which are arranged in a circle. The second light-emitting diodes 204 are arranged on the second light-emitting body 200. The second light emitting diodes 204 may emit a different color temperature and / or a different light color. The different types of light emitting diodes 204 may be arranged by sectors.

Referring to Fig. 13, a user interface for setting a lighting pattern of the room lamp is shown. The user interface can be on a portable electronic device, such as mobile phone, smart phone, a

Tablet computers can be displayed, which may have an orientation device. The dark illustrated portion 306 corresponds to an area to be illuminated, which is to be illuminated by the room lamp. The more often a user touches a location 306 and / or an area 306 on the touch screen user interface after a first icon 302 has been pressed, the brighter that area will be illuminated. Alternatively or in addition, a partial area can be illuminated brighter by the room light, the faster it is painted over a partial area 306 on a touch-sensitive screen or this partial area 306 is touched. Alternatively, or in addition, a subarea can be illuminated the brighter, depending longer and / or the more touches a sub-area 306 of the touch-sensitive screen and / or wiped over this.

The illumination of an area to be illuminated can be reduced by touching a deletion symbol 304 and then touching the area 306 whose illumination is to be reduced. The longer a spot 306 is touched, the faster it is painted over a partial area 306, and / or the more frequently it is painted over a spot or a partial area 306, the more the illumination can be reduced. On the user interface third symbols can be arranged, by means of which the

Lighting the room lamp to full power or can be turned off. Further, a slidable icon 308 may be displayed on the touch-sensitive screen, by means of which the illumination of the room lamp as a whole may be increased or decreased.

The user interface shown in FIG. 13 can be used both for controlling the

Light emitting diodes 122 on the first luminous element as well as for the control of the second

Light emitting diodes 204 are used on the second luminous 200. It can also be controlled several room lights These can be two different

User interfaces are used.

Referring to Figure 14, which illustrates a user interface of a

Touchscreen displays at different colors and

Color temperatures are displayed. The user can change the light output and / or the color of the light emitted by the room lamp by touching a desired color temperature or desired color.

The room lamp comprises a transmitting and receiving device 192 (see FIG. 1) with which the information about the partial areas to be illuminated, the color temperature and / or the color output are received. Further, the orientation of the mobile electronic device is transmitted to the user interface for controlling the light output.

The orientation determining device of the mobile electronic device may be a compass.

The room lamp comprises an orientation determination device 194, for example a compass. On the basis of the signals from the orientation determining device 194 and the orientation of the mobile transmitted by the mobile electronic device electronic device can in one embodiment, the receiving device 192 to transform the data on the subregions to be illuminated in the coordinate system of the room lamp and drive the corresponding light-emitting diodes.

In another embodiment, the room light transmits via the transmitting and receiving device 302, the orientation of the room lamp 200 relative to the mobile electronic device. The mobile electronic device adjusts a representation of the area to be illuminated to the transmitted orientation.

The data can be transmitted over an IP network, Bluetooth or any other network (NFC, near field communication).

If multiple room light used in a room, additional information about the duration of wireless signals can be determined, for example, the orientation and / or position of the mobile electronic device.

FIG. 15 shows a section through a room lamp 1 according to the invention. The room lamp is attached by means of a cable 22 to the ceiling. It is understood that the room lamp can be attached to any other lamp stand. On a circuit board 20, the first light emitting diodes 122 are directed downward and the second light emitting diodes 204 arranged upward.
