Description

The invention relates to a portable light-emitting device comprising at least one support with light sources, a power source for the light sources and a control unit for controlling the light sources according to the preamble of claim 1.

Numerous disorders of human condition are due to lack of light, especially in the blue frequency range. One of these mood disorders is known as "winter depression". In general, winter depression or Seasonal Affective Disorder (SAD), which is a depressive disorder, occurs in the autumn and winter months, in addition to depressive symptoms such as depressed mood, reduction of energy level, and Anxiety, atypical symptoms such as prolonged sleep duration, increased appetite for sweets, weight gain, increased suicide rate, increased accident frequency, etc. These complaints are due to the fact that in the normal case special ganglion cells in the retina react to blue light and suppress the secretion of melatonin. If this blue light component is missing through a little sky light in winter, various symptoms of illness such as the SAD syndrome can occur.

These symptoms can be combated by artificial supply of blue light. Blue light is therapeutically effective and is effective not only for seasonal depression, but also generally for energy and light deficiency, jet lag, or premenstrual syndrome (PMS).

Therefore, various devices have been proposed to artificially produce and deliver blue light to the human eye. In most cases, these devices are designed as stationary devices, in front of which the person to be treated has to sit or lie. These devices thus have the disadvantage that a therapy carried out with them is difficult to integrate into everyday life. Instead, devices that do not require daily activity restrictions would be preferable. For this purpose portable devices have been proposed. From WO2006 / 109969 Al, a device is known in which a bow-shaped holding part can be hooked to the ear cup, to which a rod-shaped carrier is attached. At the end of this rod-shaped support a light source is attached, which is thus located in the temple area. However, such a device is hardly suitable for daily use in public because of its size, shape and weight, and particularly not applicable to eyeglass wearers. Furthermore, it is impractical to handle, store and transport. Moreover, it is limited to the arrangement of a single light source at the end of the rod-shaped support, whereby there is a limitation in the number of light sources and their color spectrum.

It is therefore an object of the invention to provide a light-emitting device which can be carried inconspicuously close to the head with high wearing comfort and, in particular, allows a simultaneous wearing of the device with commercially available spectacles. Furthermore, the handling, storage and transport of corresponding devices should be facilitated.

These objects are achieved by the features of claim 1. Claim 1 hereof relates to a portable light-emitting device comprising at least one light source carrier, a light source power source, and a light source driving controller, which is arranged to carry the carrier as a flexurally elastic carrier tape, and at both ends of the carrier tape, respectively a holding body is provided, the holding bodies containing the power source and the control unit and being distributed on the carrier tape between the two holding bodies distributed at least two light sources or light source groups along the longitudinal direction of the carrier tape, which are connected to the power source and the control unit.

The invention thus provides, due to the use of a flexurally elastic carrier tape, an extremely thin embodiment of the carrier, which is flexible in the longitudinal direction of the carrier tape. The carrier band can thus be applied in an arc shape from one area of the wearer's temples through the upper viewing area of the eyes to the other area of the temples. The fixation on the head of the carrier takes place by holding bodies arranged on both sides at the end of the carrier band, which in particular can be designed such that they represent a counterweight to the portion of the carrier band which projects freely from the region of the support of the carrier with respect to the contact points of the carrier band at the ears. The carrier tape can thus be fixed to the head of the wearer without support point on the wearer's nose, and is held in place only by achieving a balance between the portion of the carrier tape extending freely in the viewing area of the eyes and the holding bodies located behind the ears. The flexural elasticity of the carrier tape means that, although the carrier tape is flexible in the longitudinal direction of the carrier tape, it is sufficiently stiff in the transverse direction of the carrier tape to be able to absorb forces acting in the carrier tape plane perpendicular to the longitudinal axis of the carrier tape. Further stabilization of the carrier tape may be achieved by frictional forces between the templating band and the temple area, as well as the clamping action of the holder body between the pinna and the head of the wearer. Since in this way no support point on the nose of the wearer is required, the device according to the invention can also be used by spectacle wearers. In this case, the carrier tape usually runs along an upper frame part of the spectacles and is usually hardly visible after execution of the spectacles. The erfmdungsgemäße device can thereby also be worn in everyday life easily for longer periods.

The holding bodies are also used according to the invention as a receptacle for the power source and the control unit. According to the invention, the light sources are arranged distributed on the carrier band between the two holding bodies as at least two light sources or groups of light sources along the longitudinal direction of the carrier band and are preferably connected to the power source and the control unit via a flexible printed circuit board. The light emission takes place in an eye-oriented manner, that is to say in the direction of the eyes of the wearer, with one light source or light source group in each case being directed in its light emission into one eye of the wearer. The light sources are arranged for this purpose on that side of the carrier tape, which faces the eyes.

The light sources are preferably designed as light-emitting diodes (LEDs) for a color spectrum in the blue or blue-white light region, if the device according to the invention is to be used for the treatment of winter depression. For beam shaping of the emitted light, it is proposed that the carrier tape is provided with a transparent envelope which, in the region of the light sources, preferably performs a light beam shaping through a bead protruding from the carrier tape. Since the transparent envelope is optically more dense than the surrounding air, refraction of the emitted light from the bead into the surrounding air causes refraction from the solder. This refraction of light can be used to focus the emitted light in one of the two eyes by making the envelope bead-like in this area and thus acting as a lens.

Preferably, the light sources are independently controllable by the control unit. This measure is particularly advantageous when using two groups of light sources, since, for example, the brightness of the different light sources of a light source group can be regulated independently of one another. However, any color patterns can also be formed in this way, or the light sources can also be used as status displays of various operating parameters, such as the power source and the like. The use of two groups of light sources also allows adjustment to different eye distances by activating appropriately spaced light sources. However, the driving of the light sources can also be used, for example after starting the device, a gradual increase in light brightness and a change in the light frequency from incipient red to orange and yellow to the last blue light or blue-white light to simulate a sunrise. Likewise, when the device is turned off, this process can be reversed to simulate sunset.

Since the activation of the individual light sources can take on complex forms, especially when using two light source groups, it is also proposed that the

Control unit with an external device, preferably a mobile phone, is connectable by means of a wireless connection. In this way, computing power can be transferred to the mobile phone and a simple graphical user guidance, such as for selecting color variants, light emission sequences or a user-defined, timed light emission enabled. The status of the device according to the invention may also be indicated on the external device, e.g. the state of charge of the power source. Furthermore, the device according to the invention can thus also become the subject of correspondingly specialized mobile application software ("apps").

Further, since the carrier tape is held at the head of the carrier by achieving a balance between the portion of the carrier tape extending freely within the field of vision of the carrier tape and the holding members disposed behind the ears, it may further be provided that the free portion of the carrier tape measured along the carrier tape is length adjustable. The free portion of the carrier tape is the portion of the carrier tape lying between the two holding bodies. As will be explained in more detail below, the holding body can also be fastened on a carrier which is displaceable or pivotable relative to the carrier belt, or the respective holding body can be surrounded by a housing which can be displaced relative to the carrier belt. In these cases, the free section of the carrier belt is that section which lies between the two carriers or between the two housings. In this way, the portable device can be adjusted to different head diameters to achieve optimum fit of the carrier tape. Only in exceptional cases, the use of a nose clip to fix the 'carrier tape will be required.

Furthermore, it is proposed that at least one of the holding bodies has a magnet. The magnet is assigned a counterpart arranged on the other holding body and suitably designed, for example in the form of a metal plate or a second magnet. The magnet and counterpart may be designed in such a way that the holding bodies can be fastened to each other, thereby facilitating the storage of the device according to the invention when not in use. The carrier tape can be wound or rolled up due to its flexibility and held in this state due to the mutually adhering holding body. In this way, the device can be stored in a box or the like to save space.

However, the magnet of the respective holding body can also be designed so that it is electrically conductive for coupling to an external charging device and the current source can be charged via a charging circuit connected to the magnet. The storage location of the device according to the invention can thus also be designed as a charging device, so that at the same time a charging of the power source takes place during the storage. In order to avoid unintentional short circuit due to contact of the holding bodies when the portable device is removed, it can be further provided that the charging circuit has a switch which can be closed by magnetic force. For such a device can be provided in a corresponding manner, a charging device having a receptacle for the carrier tape with an activation magnet for the switch, and magnetically coupled with the magnets charging contacts. The activation magnet can now be placed in the receptacle so that when inserting the carrier tape with its Haltekörpem in the recording of the charging device of the activation magnet comes in the vicinity of the switch and closes the charging circuit. At the same time, the holding bodies with their magnets are magnetically coupled and fixed to the charging contacts of the receptacle. In this way, the charging circuit is closed, with the charging current flowing from a power supply of the receptacle via the charging contacts, the electrically conductive magnets of the holding bodies and the closed switch of the charging circuit into the current source of the portable device.

Furthermore, it is proposed that additional elements in the form of a camera, a position sensor, a temperature sensor or a display, preferably one display per eye, are arranged on the carrier band.

The invention will be explained in more detail below by means of exemplary embodiments with the aid of the attached figures.

In the following, the invention will be described in more detail with reference to the attached figures, wherein the various embodiments and their properties are explained in particular.

To that end, there is shown in Fig. 1 a portable ophthalmic emission device according to the present invention in use, wherein a flexurally elastic carrier tape 1 with light sources 7 (seen approximately in Fig. 3) is placed on the user's head and between the pinna and the head of the wearer extends into the back ear area. In this case, the carrier tape 1, which is flexible in the longitudinal direction and rigid in the transverse direction, at both ends in each case a holding body 2, which are arranged in the use position in each case behind an ear of the user. The light sources 7 are directed towards the user's eyes in their light emission and are distributed along the longitudinal direction of the carrier tape 1, wherein in Figs. 3 and 4, light beams of the light sources 7 directed towards the eyes are shown in the form of arrows.

2 a shows a first embodiment of an open holding body 2 of the portable device, the holding body 2 having a power source, for example in the form of a rechargeable or exchangeable battery 3, a control unit 4, a switch 5 for switching on and off and a magnet 6. If necessary, the button 5 can also be used to activate and deactivate different functions of the device. FIG. 2b shows a second embodiment of an open holder body 2 of the portable device with a rechargeable battery 32 as a power source. This embodiment appears particularly advantageous because the entire holding body 2 can not only be made flatter, but also as a closed body. When using a battery 3, an interchangeability of the battery 3 must be ensured, and thus a possible opening of the holding body 2. In the case of a rechargeable battery 32 as shown in Fig. 2b, however, the holding body 2 may also be designed as a waterproof plastic body. Furthermore, a displaceability or tiltability of the holding body 2 relative to the carrier tape 1 can be realized more easily, as will be explained in more detail below with reference to FIGS. 27-29.

In Fig. 2c, an embodiment is shown in which the power source in the form of a battery 32 and the magnet 6 are arranged in a first holder body 2, and the control unit 4 with the button 5 and a charging socket 29, such as a USB socket for charging the battery 32 in the second support body 2, wherein the charging socket 29 for receiving a corresponding charging plug 30, such as a USB connector is used. The control unit 4 and the power source as well as allfallig other electronic components must therefore not be located in one and the same holding body 2, but can also be arranged distributed on both holding body 2.

FIG. 3 is a detail view of the portable ophthalmic emission device of FIG. It can be clearly seen here that the portable device is disposed approximately at the level of the eyebrows during use in the upper viewing area of the user, with the light sources 7 arranged on the carrier belt 1 emitting in the direction of the eyes. Moreover, it can be seen that the carrier tape 1 preferably comprises a carrier material 8 and a printed circuit board 9 attached to it, to which the light sources 7 are arranged.

Fig. 4 is a plan view of the portable ophthalmic emission device in use, with only the eyes schematically shown by the user. In this case, the light sources 7 form two groups, each of which is directed in its light emission to an eye of the user and focused on the relevant eye.

Fig. 5 shows an embodiment of the internal structure of the carrier tape 1 of the portable device, wherein a transparent enclosure 15 is provided around the substrate 8 and the circuit board 9. In the region of the light sources 7 for light beam shaping, this transparent envelope 15 has a bead 16 projecting from the carrier tape 1 in the direction of the eyes. Since the transparent envelope 15 is optically more dense than the surrounding air, upon the passage of the emitted light from the bead 16 into the surrounding air, refraction from the solder occurs. The bead 16 thus serves as a lens for focusing the emitted light into one of the two eyes.

Fig. 6a and Fig. 6b respectively show a side view of the portable device of Fig. 1, wherein the support body 2 are slidably disposed on the carrier tape 1 in order to adjust the measured along the carrier tape 1 distance between the two Haltekörpem 2 and thus in-use a state of equilibrium between the carrier tape 1 and the Haltekörpem 2 zuerzielen. Figures 7a and 7b show another way of balancing or equilibrium state in which the carrier tape 1 or the whole apparatus is displaced relative to the ears of the user. In addition, as shown in Figs. 8a and 8b, in each of the two holding bodies 2, a cavity 10 may be arranged in which a weight 11 for balancing is located. ;

Moreover, as shown in Fig. 9, on the carrier tape 1, a nose-distance holder 12 may be arranged for properly spacing the light sources 7 from the eyes of the user and as additional support for the carrier tape 1, the nose-distance holder 12 preferably being attachable and having different embodiments, for example normal to the carrier tape 1spend, or in the form of a loop.

FIG. 10 shows two different bending states of the flexurally elastic carrier tape 1 if the carrier tape 1 is made resilient, the inner layer of the carrier tape 1 shown in FIG. 10 corresponding to a tension-free condition, and the outer layer of the carrier tape shown in FIG .1 a tense state. This tensioned condition can be used to stabilize the carrier tape 1 on the wearer's head since the frictional forces between the temples 1 and the temples are increased. In addition to the clamping action of the body 2 between the pinna and the head of the wearer, the grip is sufficient so that no Support point on the nose of the wearer is more necessary, and the inventive device can also be used by spectacle wearers. It should be noted, however, that a resilient action of the carrier tape 1 is not a necessary characteristic of the flexurally elastic carrier tape 1.

The flexurally elastic carrier tape 1 is flexible in the longitudinal direction and stiff in the transverse direction, wherein the carrier tape 1 or the carrier material 8 and the printed circuit board 9 are flexible in the longitudinal direction such that they can also be rolled up, as in FIGS. 11 to 12 Hereinbei preferably at least one holding body 2 has a magnet 6 and the second amanderen end of the carrier tape 1 arranged holding body 2 a suitably formed counterpart, for example in the form of a second magnet 6 (see Fig. 1 la-c) or a metal plate 31st (see Fig. 12e), whereby it is possible for the carrier tape 1 to be fixed in the rolled-up state, as shown in Fig. 11c and 12e, for example. The carrier tape 1 can also be arranged in a case 14 for safekeeping, as can be seen in FIG. 12d. 12e shows a rolled-up arrangement of the device according to the invention for an embodiment of the holding body 2 according to FIGS. 2b and 2c, that is to say with a narrow and preferably slightly curved battery 32.

FIGS. 13 and 14 show that the holding bodies 2 can be arranged on the carrier tape 1 in the form of a plug-in connection (FIG. 13) or by means of an intermediate plug (FIG. 14). This plug-in capability also allows interchangeability of the holding body 2, about to be able to change between an embodiment of the holding body 2 according to Fig. 2a and Fig. 2b, or to allow better adaptation to the head shape of the respective carrier by using differently shaped holding body 2.

Moreover, in a further embodiment, the holding bodies 2 can be rotatably arranged on the carrier tape 1, as can be seen in FIG. 15, whereby the apparatus can be stowed more easily. Furthermore, an individual adaptation to the user is possible, whereby a higher wearing comfort is achieved.

FIG. 16 shows an axonometric view of the device according to the invention which is concealed from an upper frame part of a pair of spectacles. Due to the narrow executability of the carrier tape 1, use of the portable device is also readily possible for spectacle wearers.

Preferably, the light sources 7 are individually controllable, whereby, for example, the brightness of the sometimes differently formed (red, green, blue) light sources 7 can be regulated independently of each other, whereby, among other things, any color patterns can be formed. To illustrate this is shown in Figs. 17a and 17b shows a temporal sequence of activated light sources 17 and deactivated light sources 18. However, it can also be understood from Figs. 17a and 17b that the use of two light source groups allows the light emission to be optimized for different eye distances by selecting the activated light sources 17 at a corresponding distance.

In addition, different arrangements of light sources 7 arranged on the carrier tape 1 are shown in FIGS. 18a to 18c, wherein exactly two light sources 7, of which one is directed in its light emission into an eye of the user, are arranged on the carrier tape 1 according to FIG. According to FIG. 18b, two groups of light sources 7 are arranged on the carrier tape 1, one of which is directed in its light emission into an eye of the user. On the other hand, according to FIG. 18a, a continuous row of light sources 7 can also be used, which however, in the course of their activation, are usually controlled in the form of two light source groups.

Moreover, as shown in Fig. 19, additional elements may be arranged on the carrier tape 1, for example in the form of a camera 19, a position sensor 20 or a temperature sensor 21. As indicated in FIG. 20, at least one display 22, preferably one display 22 per eye, could be arranged on the carrier tape 1 in addition to the light sources 7, not shown.

Fig. 21 shows a possible course of the brightness of the light of the light sources 7 as a function of time, wherein it can be seen, for example, that a gradual increase in light brightness and a change in light color from incipient red to orange and yellow to the final blue light or Blue-white light can take place to simulate a sunrise. Similarly, when the device is turned off, this process can be reversed to simulate a sunset. The simulation of a

Sunrise or sunset can be with several different colors. Light sources 7 (red, green and blue) are accomplished.

In a further embodiment, additional lighting elements can be arranged on the side of the carrier tape 1 facing away from the user's eye, as can be seen in FIG. These luminaries thus do not emit their light in the direction of the user's eyes.

In addition, the portable device can also be controlled by means of an external device 23, for example a mobile telephone, as shown in FIG. This has the additional advantage that, for example, the color or brightness calculations for driving the light sources 7 do not have to take place in the portable device itself, as a result of which computing power can be saved to the control unit 4 and a more comfortable operation and status polling of the device can be achieved. The specified by means of their own application software control can be sent in another following wireless, for example by means of WLAN or Bluetooth from the external device 23 to the arranged in the holding body 2 control unit 4, which controls the light sources 7 and further regulate about the light brightness of the light sources 7 in compliance with the transmitted data. In this case, it is also possible for data acquired by the camera 19, the position sensor 20, the temperature sensor 21 or other sensors and the light sources 7 to be used for purposes of biofeedback by means of a corresponding program which is likewise stored on the external device 23.

FIG. 24 shows an embodiment of the holding bodies 2 in which the magnet 6 is electrically conductive for coupling to an external charging device and the rechargeable battery 3 is chargeable via a charging circuit connected to the magnet 6. The charging circuit in this case has a switch 26 which can be closed by magnetic force. Fig. 25 shows an axonometric view of an associated charging device comprising a receptacle 24 and a charging battery 28 and / or a power supply as a power supply. In addition, two activation magnets 25 and two charging contacts 27 for the two holding bodies 2 are provided in the receptacle 24. The receptacle 24 is designed such that the carrier tape 1 can be inserted with the two Haltekörpem 2eollollt, wherein in the state of charge shown in FIG. 26, the magnets 6 are in contact with the charging contacts 27 and the switches 26 are in the vicinity of the activation magnet 25. In this way, by means of the activation magnets 25, the switch 26 and thus the charging circuit are closed, the charging current subsequently being transferred from the charging battery 28 of the receptacle 24 via the charging contacts 27, the electrically conductive magnets 6 of the retaining bodies 2 and the closed switch 26 of the charging circuit into the rechargeable Battery 3 of the portable device flows.

FIGS. 27a-b show detailed views of further embodiments with a holding body 2 according to FIGS. 12b and 12c. The narrow executability of the battery 32 and thus the holding body 2 favors embodiments in which a change in the overall length of the device according to the invention is possible, such as by the holding bodies 2 are each surrounded by a relative to the carrier tape 1 displaceable housing 34, as shown in Fig. 27. The displaceability of the housing 34 relative to the carrier tape 1 shortens or lengthens the overall length of the device and thus allows for better adaptability of the device to individual head shapes. FIGS. 28a-c show detailed views of a further embodiment in which a carrier 33 is provided on which the respective holding body 2 is rotatably and slidably mounted. In this way, not only the overall length of the device can be adjusted, but also the relative angle of the carrier 33 to the carrier tape 1, whereby additional wearing comfort can be achieved. A further embodiment for achieving an adaptability of the overall length of the device is shown in FIGS. 29a-c, wherein the respective holding body 2 is displaceably arranged on a carrier 33, which in turn is designed for maximum wearing comfort in the ear area.

The invention thus provides a light-emitting device which can be worn with high wearing comfort inconspicuously close to the head and in particular enables a simultaneous wearing of the device with commercially available spectacles. Furthermore, the handling, storage and transport of corresponding devices are facilitated.
