Abstract

In order to achieve the most pronounced psychological effect of light, two core problems were identified, which the present invention solves: On the one hand, the user must become aware of the lighting and initially turn his gaze towards it and, on the other hand, he must maintain this gaze for as long as possible. To do this, it is necessary that the lighting mood presented has a harmonious effect on the user and gives them a lighting mood that suits the situation. The high flexibility of the device with regard to the emitted light also brings with it the challenge of making this flexibility profitably accessible to the user. The present invention solves the core problems with the help of four technical features: the separate controllability of individual light sources, the dynamic change of them emitted light in intensity and light color/spectral distribution, the adaptation of the light to activities/emotions/people in the environment, as well as the formation of a three-dimensional depth effect through the use of light-influencing material. This enables a device that takes the situation in the environment into account and automatically presents the user with a suitable lighting mood. It therefore appears harmonious and perfectly suited to the respective situation and stimulates the user to look for a long time.

Description

The psychological and physiological effects of light have been known for many years (see, for example, A. J. Elliot, M. D. Fairchild, A. Franklin: “Handbook of Color Psychology”, Cambridge University Press, 2015). The intensity and color of light are particularly important, but the dynamics with which both properties change over time also have an influence on the effect of light. While natural light can only be shaded but cannot be influenced further, artificial light, particularly through lighting technologies such as inorganic and organic light-emitting diodes, offers the advantage of a highly adaptable light source. These advantages are already being used in the context of “Human Centric Lighting” (HCL), i.e. user-centered lighting, for example to vary the blue and red components in the light spectrum and thus adapt the lighting effect according to the effect of natural light (see for example P. Boyce : “Exploring human-centric lighting”, Lighting Research & Technology. 2016;48(2)). Conventional lights are usually used, which enable light with a variable spectrum to be emitted using different light sources. This light is traditionally controlled according to the course of the day and does not take into account any particular activities/emotions/people in the environment. The effect of light is primarily subconsciously physiological, just like natural light affects the body. The present invention expands the lighting effect in particular to include a psychological component, which does not take on the technical function of a lamp, but rather creates a mood as ambient lighting. In order to achieve the most pronounced psychological effect possible, two core problems were identified in advance of development, which the present invention solves: On the one hand, the user must become aware of the lighting and initially turn his gaze towards it and, on the other hand, he must maintain this gaze for as long as possible. For the effect, it is irrelevant - at least during periods of typical usage scenarios - whether the gaze is continuous or is interrupted again and again. Only the total duration of the gaze is decisive for the effect. The present invention solves the core problems with the help of four technical features: the separate controllability of individual light sources, the dynamic change of the light emitted by them in intensity and light color/spectral distribution, the adaptation of the light to activities/emotions/people in the environment, as well as the Creating a three-dimensional depth effect through the use of light-influencing material.

The combination of dynamic changes, i.e. changes over time, of the intensity and light color/spectral distribution of individual light sources separately from one another and a three-dimensional depth effect has been proven to have the effect that the device generates attention and the user's gaze is “attracted”, similar to a fireplace or an aquarium. In order for the device to be held by the user either in the direct field of vision or at least in the peripheral field of vision for as long as possible, the lighting mood presented must have a harmonious effect on the user and provide him with a lighting mood that suits the situation. The high flexibility of the device with regard to the emitted light also brings with it the challenge of making this flexibility profitably accessible to the user. In order to do justice to both aspects, the present invention integrates a microelectronic control that detects at least one parameter that allows the detection of activities and / or emotions and / or people in the environment and, depending on this, the intensity and / or spectral distribution of the Light emitted by light sources is influenced. This enables a device that takes the situation in the environment into account and automatically presents the user with a suitable lighting mood. It therefore appears harmonious and perfectly suited to the respective situation and stimulates the user to look for a long time.

As a rule, one of two ways is implemented to react to emotions, activities and people in the room with light: Positively connoted emotions/activities/people in the room are reinforced by appropriate lighting moods, while negatively connoted emotions/activities/people are reinforced by corresponding ones lighting moods are counteracted. For example, the activity of partying with friends can be supported by strong colors with quick changes and movements, while a loud argument can be countered with soft colors and calm movements to calm people down, or light with a high proportion of blue and dynamic light for an early morning breakfast Movements ensure an activating start to the day.

The detection of parameters that allow conclusions to be drawn about the activity in the environment is crucial for the functionality of the device. Depending on the activity, one parameter of the environment is sufficient or several parameters must be evaluated to enable detection. It is often useful to take the time into account as an additional parameter, as this usually has a lot of significance regarding activities in the room. In the Evaluation of the parameters ideally takes into account the context in which the device is located. For example, simply by evaluating the temperature in a room, the activity in the room is recognized, for example a guest moves into his hotel room and switches on the heating in the room. By evaluating the ambient brightness, the case of entering the room in the evening can also be recognized by detecting the rapid increase in ambient brightness caused by switching on the room lighting. This shows that the time course of the value of the parameter can also be relevant to determine the activity. If the “ambient brightness” parameter is supplemented and/or replaced by the light color and/or color temperature and/or the spectral distribution of the light in the environment, further conclusions can be drawn about the activity. This makes it possible, for example, to recognize whether artificial light or natural light is illuminating the room and thus to determine activities such as cleaning the room with maximum brightness of the artificial light or, for example, relaxing in the evening by a fireplace or, for example, the incidence of natural light by opening the curtains after getting up in the morning.

The detection of noises can, for example, be used to record activities in the household such as vacuuming, blow-drying, mixing, cooking, clearing dishes, but also the ringing of the doorbell, the alarm clock and/or the telephone. More detailed insights into activity in the room can be obtained by recording speech using a microphone. For example, recorded conversations are evaluated using artificial intelligence methods and assigned to them known activities and/or emotions trained in the models. In a simple case, this can be done using keywords, although complete sentences should be evaluated for reliable results. On the one hand, activities can be recognized such as general conversations, telephone calls, games, stories read out, films, but also detailed information about the respective emotions of the people, such as arguments with an aggressive tone, a worried mood, sadness or joy.
Music and/or sounds can also be recorded via a microphone, enabling activities and/or emotions to be recognized. On the one hand, the mood of a piece of music and thus the mood in the room can be determined based on the pitch, volume and speed; on the other hand, specific pieces of music can be linked in advance to moods, which are then referenced when the respective piece of music is recognized. In addition, the sound frequency spectrum can be evaluated directly, for example to convert the sound level recorded for certain frequencies directly into intensities of the emitted light. For example, a light source can represent a specific frequency range. This type of control is based on the assumption that there is a direct connection between music and/or sound frequency spectrum on the one hand and the emotion and/or activity in the room on the other hand, which is why a direct mapping of music to the lighting mood is possible. This assumption is justified in many cases because music - similar to light - has a direct influence on the mood and emotions of people in the room and therefore a direct implementation of music in light transfers the effect of the music to the lighting and thereby strengthens it.

The scent in the room has a comparable effect on the mood and emotions of people. Therefore, this can be a suitable parameter for recognizing emotions, but can also make certain activities recognizable. With appropriate sensors (as described for example in US9696291 B2 ) activities such as cooking, roasting, baking, but also perfuming with room scents or decorating with freshly cut flowers can be recorded and accompanied with appropriate lighting.

Another parameter for detecting activity in the room is the number of people in the room. This can provide a more reliable statement about activities, especially in conjunction with other parameters. For example, the number of people in the room can be supplemented with the detection of ambient noise in order to reliably detect the activity of a party, for example. The number of people can be recognized, for example, by recording and evaluating spoken language, whereby artificial intelligence methods can provide suitable models, through infrared sensors or indirectly through the recognition of devices that are in the room and, for example, by Radio signals emitted by them can be detected (so-called “beaconing”). Assuming that a person is wearing a personal device (e.g. smartphone, SmartWatch, fitness tracker, headphones), the latter can also be used, for example, to distinguish people from each other and to implement personal lighting moods, depending on who is in the room located. In addition, activities can also be directly traced back to devices in the room, for example reading a book when an e-reader is switched on in the room or playing a video game when a video game controller is switched on in the room.

Furthermore, the evaluation of movements supports the detection of people and/or activities in the room. The level of detail of the activity recognition depends on the number of dimensions in which the motion recognition takes place. This can be seen as a distance in one dimension and thus as a liner movement, two-dimensionally as a movement in a surface or as a movement in a three-dimensional space, such as using a stereo camera (comparable DE102007023140A1 ), are recorded. For example, with the help of machine learning methods, known movement patterns can be identified from the recorded movements and conclusions can be drawn about which activities are most likely to be carried out in the room. This can be used, for example, to recognize activities such as reading a book, sitting on a couch, eating at the table, dancing in the room, working on a PC, drinking a drink or even singing on one Stage.

The air quality parameter is an indicator of activity, especially in rooms used by several people. For this parameter, sensors can measure CO2, CO, VOC, ozone and/or particulate matter, for example. For example, in classrooms, lecture rooms or offices, the CO2 content in the air can provide an indication of how long the room has been actively used by people without providing fresh air and can thus vary the lighting mood depending on the time of use. This can help to sensitize those present to a regular supply of fresh air and thus prevent their ability to concentrate from decreasing as the CO2 content in the room air increases.

The humidity, for example, can be used as a parameter to indicate the activity of heating, which usually causes it to decrease. The lighting mood can therefore follow this activity. If a parameter that represents the content of a screen is evaluated to control the lighting mood, the content of the screen and thus the activity of the people in the room can be deduced, for example, by processing colors, color proportions, color changes and/or frequencies of content change. If it is assumed that a film or an entertainment program is playing on the screen, the dark image content can, for example, indicate a dark mood in the film and thus, for example, the activity “crime evening” or “watching a horror film” which then determines the lighting mood in the room can be adjusted. Colorful image content with rhythmic color changes, for example, suggests “watching a music show”, while different shades of blue with gentle movements, for example, indicate underwater images, which can be taken into account in the lighting mood.

By evaluating at least one parameter that represents events in a computer game, it is possible to draw specific conclusions about the activity and/or emotion of a person in the room, for example when the goal of the game is achieved, a high score is cracked and/or elimination from the game game takes place. The lighting mood can accordingly enhance the activities and emotions in the game by adjusting according to the events.

The same applies to the example of at least one parameter that represents events in virtual reality (VR) and/or augmented reality (AR). This makes it possible to generate a comprehensive atmospheric experience in which the effect of the computer-generated event on the people in the room is enhanced by the appropriate lighting mood.
Regardless of the parameter taken into account, it is often possible and expedient to recognize activities from the respective parameters using artificial intelligence and/or machine learning methods, as there may be recurring patterns to which an activity can be assigned. For this purpose, for example, an AI-based, intelligent assistance system can be used to control the device. This is able to analyze texts that are spoken and/or read by the user using a “Natural Language Understanding” and “Sentiment Analysis” approach. The data obtained is interpreted and evaluated so that the system displays a lighting mood that is adapted to the content in real time.

An AI-based control also makes the flexible possibilities of lighting technology easily accessible to the user. It puts the user at the center and reduces the necessary need for interactions between user and device. Instead, the user and his activities are analyzed and the lighting mood is flexibly adjusted to the user's needs. This increases comfort for users in private environments and saves time and money for professional users in commercial environments. In addition to this aspect, climate-based control offers another significant advantage. It not only allows the activity-related selection of predefined lighting moods, but also the creation of lighting moods that match the activity based on the analyzed data. Creating content in this way creates the great added value that the range of the lighting experience increases many times over, because not for everyone For every conceivable action, an ideally coordinated lighting mood can be predefined in advance.

A first exemplary embodiment of the device for influencing the lighting mood consists of a regular arrangement of LED light sources on a circuit board with an aluminum core, which are mounted in a 6 by 6 grid on a square recycled plastic plate. Three light sources are placed at each intersection of the grid, each emitting the light colors red, green and blue. In this exemplary embodiment, the distance between the crossing points is approximately 10 millimeters, while the distance between the three light sources at the crossing point is approximately 0.1 millimeters. This gives the viewer the impression that the three light sources merge into a single pixel, with the spectral distribution of the emitted light being influenced by setting different intensities of the individual light sources. Each of the light sources is connected to an intensity control integrated circuit which is placed on the printed circuit board near the respective light source and contains the data for control via a wired bus system from a central data processing unit in the device. This central data processing unit is integrated into a wireless network and thus communicates with other devices that provide the parameters required to detect activity in the environment. In the exemplary embodiment, signals from a computer game are evaluated, which are converted into the appropriate lighting mood. In this way, the user's activity is recorded in detail and reacted to, for example when he overtakes an opponent in a racing game and the light shows blue pulsating waves, when he knocks down an opponent in a fighting game and the light flashes bright white when he is in a puzzle game sets a new time record and the light sparkles in shades of green or when he is eliminated from a “Jump & Run” game and the lighting slowly changes to dark red. The user sees the light sources with a three-dimensional depth effect, which makes them appear not as points, but as arcs that appear deeper than the device itself. This effect is achieved by a textile fabric (for example according to EP2284306B1 ) which is braced at a distance of around 30 millimeters above the light sources on an aluminum frame, which also holds the back panel made of recycled plastic. This creates a lighting effect that attracts attention and allows the device to achieve its effectiveness.

A second exemplary embodiment of the device for influencing the lighting mood consists of a regular arrangement of LED light sources on a rectangular circuit board made of a flame-retardant epoxy resin-glass fabric composite material in a grid of 14 by 28. Four light sources are placed at each intersection of the grid, each emitting the light colors red, green, blue and white. In this exemplary embodiment, the distance between the crossing points is approximately 50 millimeters, while the distance between the four light sources at the crossing point is approximately 0.1 millimeters. This gives the viewer the impression that the four light sources merge into a single pixel, with the spectral distribution of the emitted light being influenced by setting different intensities of the individual light sources. The light sources are electrically connected to one another in columns and rows, i.e. in a grid shape. The ends of the individual columns and rows are each connected to a column and row driver and an integrated circuit that can switch the individual light sources on/off independently of each other or at a certain intensity via multiplexing (alternatively Charlieplexing). The circuit receives the control data from a central data processing unit via a wired bus system. This central data processing unit is integrated into the device and has a connected microphone through which music and sounds in the environment are recorded and evaluated. The lighting mood is then created through audio visualization using, for example, a spectrum analyzer, correlation display, peak/level meter and/or waveform. The user sees the light sources with a three-dimensional depth effect, which makes them appear not as points, but as arcs that appear deeper than the device itself. This effect is achieved by a textile fabric which is clamped to an aluminum frame, which also holds the rear circuit board, at a distance of around 50 millimeters above the light sources. This creates a lighting effect that attracts attention and allows the device to achieve its effectiveness. The textile fabric influences the emitted light, but not the sound, so that the microphone cannot be seen from the viewer's perspective, which is positive for the product design. In a variant of this second exemplary embodiment of the device, an additional function of the device is achieved in that an acoustic foam with an open-pored surface into which sound waves can penetrate is placed in the installation space around the light sources in such a way that it does not create any shading that is visible to the user light sources. As a result, the device serves to absorb sound energy and thus reduce room noise in order to additionally influence the positive effect of light in the room through a positive sound impression.

A third exemplary embodiment of the device for influencing the lighting mood consists of an irregular arrangement of 147 LED light sources, which are placed in groups of three light sources each on 49 round circuit boards made of a flame-retardant epoxy resin-glass fabric composite material. The light sources in a group each emit the light colors red, green and blue and are at a small distance - in this exemplary embodiment approximately 0.5 millimeters - from one another. The distance between these groups is irregular and was determined during construction by a pseudo-random generator in the range of 1 to 100 millimeters. Likewise, for each group, a distance at which the light sources were mounted from the rear aluminum mounting plate was determined by a pseudo-random generator in the value range from 0 to 40 millimeters. In this exemplary embodiment, at a distance of 50 millimeters, a plastic plate is attached parallel to the rear mounting plate, into which microstructures have been introduced so that they can act as a holographic diffuser (for example, similar to the component described in US20120188791A1 ) and which create a three-dimensional depth effect. For the viewer, an arc appears instead of the point-shaped light sources. Because the groups of light sources are each at a different distance from the rear mounting plate and thus also from the structured plastic plate, the viewer receives a different depth effect for each group. Groups that are at a greater distance from the plastic plate produce a longer arc that reaches deeper than groups that are closer to the plastic plate. In this example, there is also an integrated circuit on the circuit board of each group to control the intensity of the three LED light sources in the group. The circuit receives the data for control via a bus system from a central data processing unit in the device. This central data processing unit has interfaces that provide the parameters required to detect activity in the environment. In the exemplary embodiment, devices in the environment are detected via radio signals (in this exemplary embodiment via Bluetooth) in order to adjust the control of the individual light sources and thus the lighting mood, depending on detected devices in the environment and thus indirectly on activities and people. For example, based on a recognized and previously stored smartwatch in the area, it is concluded that there is a known person in the area. One of the lighting moods stored for this person and classified as positive by this person is then displayed by transmitting the stored intensities for each individual light source from the central data processing unit via a bus system to the integrated circuits in each group.

A fourth exemplary embodiment of the device for influencing the lighting mood consists of a regular arrangement of LED light sources on a circuit board with an aluminum core, which are mounted in a grid of 19 by 29 on a rectangular plastic plate. Five light sources are placed at each intersection of the grid, each emitting the light colors red, green, blue, warm white (2700 K) and neutral white (4500 K). In this exemplary embodiment, the distance between the crossing points is approximately 20 millimeters, while the distance between the five light sources at the crossing point is approximately 0.1 millimeters. This gives the viewer the impression that the five light sources merge into a single pixel, with the spectral distribution of the emitted light being influenced by setting different intensities of the individual light sources. By adding two shades of white to the three primary colors, colors in the white range of the color space can be displayed with higher light quality (i.e. color rendering, for example) and efficiency. Each of the light sources is connected to an intensity control integrated circuit which is placed on the printed circuit board near the respective light source and contains the data for control via a wired bus system from a central data processing unit in the device. This central data processing unit is connected to a host PC via a USB interface and thus communicates with devices that provide the parameters required to detect activity in the environment. In this exemplary embodiment, the image data from a camera is evaluated in order to draw conclusions about the activities of people in the room. For example, a distinction is made between whether people are sitting at a table and eating or whether people are sitting on a sofa and watching TV or whether people are lying on a sofa and sleeping. The light sources appear to the user with a three-dimensional depth effect, which makes them appear not as points, but as cross-shaped arcs that appear deeper than the device itself. From each light source in the center, two arcs appear to extend into the depths. This effect is achieved by two textile fabrics which are clamped directly one above the other at a distance of approx. 20 millimeters above the light sources on an aluminum frame, which also holds the plastic plate on the back. This creates a lighting effect that attracts attention and gives the device its effect.

A fifth exemplary embodiment of the device for influencing the lighting mood consists of a regular arrangement LED light sources on an aluminum core PCB mounted in a 2 by 45 grid on a rectangular FR4 PCB. Three light sources are placed at each intersection of the grid, each emitting the light colors red, green and blue. In this exemplary embodiment, the distance between the crossing points is approximately 10 millimeters, while the distance between the three light sources at the crossing point is approximately 0.1 millimeters. This gives the viewer the impression that the three light sources merge into a single pixel, with the spectral distribution of the emitted light being influenced by setting different intensities of the individual light sources. Each of the light sources is connected to an intensity control integrated circuit which is placed on the printed circuit board near the respective light source and contains the data for control via a wired bus system from a central data processing unit mounted on the same printed circuit board. This central data processing unit is integrated into a wireless network and thus communicates with other devices that provide the parameters required to detect activity in the environment. The circuit board with the light sources, the integrated circuits for controlling their intensity and the data processing unit are placed inside a transparent plastic tube, the wall of which is lined from the inside with a textile fabric. For the user, the light sources appear to have a three-dimensional depth effect, which makes them appear as arches that appear to protrude beyond the limits of the device's installation space. This creates a lighting effect that attracts attention and gives the device its special effect.
