Description

The invention relates to a device for illuminating a subject area, having a reflector screen comprising at least one reflection element.

Corresponding devices for illuminating a motif area, having a reflector screen comprising a reflective element, are basically known from the prior art. Umbrella-like devices provided with a reflective material on the inside of the screen are known by the term softbox. These take up a light source in their center, the emitted light of which is emitted or directed to a subject area. Such devices are relatively heavy and unwieldy when installed with a lamp. The power supply for the lighting means must also be handled in addition to the device itself. Finally, the field of application of the illuminant used can be restricted, so that it is necessary to carry several illuminants with you in order to use the illuminant with the corresponding effect depending on the application.

The invention is based on the object of specifying a device for illuminating a motif area which, in particular, offers simple and handy handling as well as a large scope of performance with regard to the lighting options or the illumination of the motif area.

The object is achieved by a device for illuminating a subject area according to claim 1. The dependent claims relate to possible embodiments of the device.

The invention relates to a device for illuminating a subject area, having a reflector screen comprising a reflection element.

The device is characterized in that in or on the reflector screen, in particular in or on the reflection element, at least one LED illuminant, in particular a plurality of LED illuminants, is or is arranged for at least partially direct and / or indirect illumination of a motif area. are. Direct illumination of the motif area means that the light emitted by the at least one LED light source is directly, i.e. H. in a direct way or without an object in the room standing in the way between the LED light source and the subject of the subject area. In the case of indirect illumination of the subject area, the at least one LED light source is arranged in such a way that the light emitted by the LED light source does not take a direct route but only after it is reflected on a reflective surface, e.g. B. Wall or ceiling of a room is "steered" in the direction of the subject. If the light emitted by the LED illuminant experiences a reflection on reflective surfaces of the device itself and then reaches the subject area directly, this is to be understood as direct illumination.

It is possible that the at least one reflection element is set up to form a three-dimensional shape, in particular a curved body with a light exit opening through which light exit opening the light emitted by the at least one LED illuminant can be exited to a motif area. In this case, at least the LED lighting means is arranged or configured or configured, at least in sections, in an interior of the body, which has a three-dimensional shape, at least during normal use. The illumination of a motif object in the motif area can generally include the generation of different light and / or shadow effects as well as influencing the image characteristics or the effect of the motif object. Typically, such devices are used to illuminate a subject object of a subject area when taking photos and / or films, with flash or continuous light devices being used. The LED lighting means described here are primarily intended to be used as permanent light sources. In this case, it may be necessary to change the location and / or the alignment of the device for illuminating a subject area, so that a low weight and easy handling are desirable. Because the reflector screen, in particular the reflective element, is provided with at least one LED light source, and especially in the event that the device does not include any other light sources besides the LED light sources, the total weight of the device is relatively low and can easily be replaced with Hand shifted or held.

The at least one LED lighting means can be arranged, for example, in or on a component of the reflector screen or in a component of the reflection element.

As an alternative or in addition, at least one LED light source can be arranged on the side of the reflector screen, in particular of the reflection element, facing the light exit opening.

At least one LED illuminant can also be arranged on the side of the reflector screen, in particular of the reflection element, facing away from the light exit opening, in this case pointing the reflector screen or the reflective element at least in sections has an opening and / or a transparent section and / or a translucent section which is arranged relative to the LED illuminant in such a way that the light emitted by the LED illuminant through the opening, the transparent Section and / or the translucent section can pass through to reach a motif area via the light exit opening. Finally, it is possible for a first LED lighting means to be arranged on a side facing the light exit opening and a second LED lighting means to be arranged on a side of the reflector screen facing away from the light exit opening, in particular of the reflection element or in a component of the reflector screen, in particular of the reflection element.

The three-dimensional, in particular arched and / or curved body formed at least in sections by the at least one reflection element can for example have a symmetrical or asymmetrical shape at least in sections. For example, the three-dimensional, in particular curved, body has the shape of a rotationally symmetrical body, i. H. the body can be rotated by defined angles on one axis, in particular on its longitudinal axis, and in the process reproduces itself again; this can also be referred to as n-fold rotational symmetry. The three-dimensional, in particular curved, body can alternatively or additionally have a rotationally symmetrical shape. For example, the three-dimensional body has, at least in sections, the shape of a pyramid, a truncated pyramid, a cone and / or a truncated cone. Here, the three-dimensional body can have the shape of a straight or inclined geometric body, in particular a polyhedron. The base area and / or possibly the top surface of the geometric body, in particular a truncated pyramid-shaped or frustoconical geometric body can be that of an equilateral, equiangular, symmetrical and / or asymmetrical n-gon (polygon). The jacket surface of the geometric body can have a straight course in section at least in sections, alternatively or additionally the jacket surface can also have a shape which is curved in section at least in sections.

Alternatively or additionally, for example, the light exit opening or a projection of the edge of the light exit opening into a plane can have an n-angular shape, e.g. B. have the shape of an equilateral, an equiangular or a regular polygon which is in particular in a main plane of extent of the light exit opening, d. H. in a plane formed by the light exit opening. The three-dimensional, in particular arched, body can, for example, have the shape of a tub, a pot, a funnel, with a tub opening or a pot opening forming the light exit opening, so that the LED illuminants are preferably in an interior of the tub-like, pot-like or funnel-like body can be arranged.

The three-dimensional, in particular curved, body can be formed, for example, by a single reflection element or by a plurality of reflection elements. If a plurality of reflection elements are used, they can be arranged in an overlapping manner, for example, at least in the position of use of the device or the reflector screen, so that the transitions of the individual reflection elements forming the three-dimensional, in particular curved, body are formed without interruption. The arched shape of the body enables the light incident on this surface to be reflected on the inside or on the surface area facing the light exit opening and thus enable the light provided by the device to illuminate the subject area to be aligned, bundled and / or focused . In other words, uncontrolled spreading of the light emitted by the device for illuminating the subject area is prevented. This aligned, bundled and / or focused light can have been generated by at least one (first) LED lamp of a first lighting device and / or by at least one further lamp, which is not necessarily based on LED technology, of another lighting device.

Alternatively or additionally, it is possible for the at least one reflective element to be set up to form a body having a three-dimensional shape, in particular a curved body, with a reflective area facing or facing the motif area, the at least one LED light source on the one facing away from the reflective area Side of the reflective element is arranged, so that the light emitted by the at least one LED illuminant reaches the subject area for indirect illumination. A device is thus provided which makes it possible to indirectly illuminate the subject area using its LED lighting means. Here, the three-dimensional shape of the body of the at least one reflective element serves on the one hand as a support means for carrying the at least one LED illuminant and, on the other hand, as a structural measure to prevent direct illumination of at least one LED illuminant carried by the reflective element, so that at least this one reflective element only indirectly to illuminate the subject area can be used. The reflective element can optionally have a reflective surface which, when used as intended, is directed towards or facing a motif area. The reflective surface can serve to reflect light directed towards the device on the motif area side and thus contribute as a surface that acts passively on the illumination of the motif area or an active component of the device in the illumination of the motif area.

It can be provided, for example, that the reflector screen and in particular the reflection element do not have any reflective and / or reflective areas for the light emitted by the device via the at least one LED lamp. In this case, the in particular umbrella-like reflector screen serves as a volume body for holding the at least one lighting device or for holding at least one LED lamp and at the same time as an obstacle to prevent light from falling into the subject area from lighting or reflection sources located behind the device.

In a preferred embodiment, the at least one LED lighting means is arranged or formed in or on the side of the reflection element facing the light exit opening. This can have the advantage that in the case of a collapsible reflector screen in its collapsed state, the at least one LED illuminant is located inside the collapsed reflector screen and the at least one LED illuminant is thus protected from mechanical influences.

It is possible for the at least one LED lighting means to be detachably or permanently attached in or on the reflector screen, in particular in or on the reflection element. A solvable, i.e. H. Non-destructively releasable attachment of the at least one LED illuminant to the reflector screen or in or on the reflective element enables an LED illuminant, for example a defective one, to be replaced. It can e.g. B. be provided that several (ie at least two, preferably a large number of) potential fastening locations for fastening an LED lamp in or on a reflector screen, in particular in or on a reflective element, and optionally all potential fastening locations with an LED lamp can be provided or an LED light source can be placed or fastened selectively at the desired fastening locations. So z. B. depending on the target of the illumination or the light and / or shadow effect to be generated on the motif area, a desired arrangement of several LED lamps in or on the reflector screen, or in or on the reflective element. So z. B. several LED lamps in a first configuration can be arranged homogeneously and / or symmetrically within the surface of the reflection element and in a second configuration inhomogeneously or asymmetrically. The detachable fastening can preferably be designed or set up in such a way that tool-free dismantling and / or mounting of the at least one LED light source is made possible. For this purpose, the reflective element can be connectable to an energy supply unit at the potential fastening locations for an LED lighting means via an energy supply interface. As an alternative or in addition, it is possible that the variable placement of the LED lamps ensures that a first LED lamp is placed in a first position on the reflector screen at a central position forming a first lamp device and in a further placement or position. is used in a further configuration of this LED lighting means in a decentralized area for at least partial formation of a further, decentralized lighting device.

It is possible that the reflector screen comprises a folding mechanism and at least one, in particular flexible, reflective element, the reflective element being able to be displaced by the folding mechanism between an open or extended use position and a folded or retracted non-use position. The expanded position of use means that in this position the at least one reflection element has a greater extent than in the folded non-use position and / or that in this position the at least one reflection element is positioned and / or aligned in such a way that at least one device-side illuminant, in particular at least one Device-side LED light source, illuminates the subject area by emitting light, or that the emitted light can be used to illuminate the subject area. The use position forms an arrangement and / or alignment of the at least one reflective element with a larger extension than is the case in a non-use position; in the non-use position the device and in particular the at least one reflection element occupy a more compact volume than in the use position. The folding mechanism can, for. B. be constructed in the manner of an umbrella, typically the reflection element can have an at least partially flexible and / or elastic property, so that a tension acts on the reflection element preferably in the position of use. The aforementioned relative displaceability of at least one LED lamp to a carrier or the relative displaceability of the at least one carrier to a reflector screen relates to a displaceability that can be achieved without folding or folding the Reflector screen and thus while this is in a use situation or use position is associated. In other words, the reflector screen remains in its position of use during the displacement of the carrier, in particular the LED light source, possibly despite certain changes in geometry, in particular at least of reflective partial areas of the reflector screen.

It can prove to be advantageous if an, in particular rechargeable, electrical energy storage unit for supplying energy to the at least one LED light source is arranged in or on the reflector screen, in particular the energy storage unit is detachably fastened in or on the reflector screen. Because the motif area is illuminated at least partially by means of LED lamps, a relatively small and lightweight energy supply unit or energy storage unit can be used to supply it with energy. Because the energy supply unit or the energy storage unit is so compact and light, the manageability of the device is increased, in particular if the device is relocated. The energy storage unit can be operated with an electrical voltage, in particular an output voltage, of 10 to 24 volts, in particular 12 to 16 volts. The performance of the power supply unit can, for. B. 60 to 250 Wh. Optionally, the energy storage unit can be connected to the reflector screen by a detachable, in particular detachable, fastening or connection without tools. For this purpose, z. B. at least one energy storage unit can be connected to the reflector screen, in particular to the reflective element, via an energy supply interface. It can prove to be advantageous if the energy supply interface or the fastening of the energy storage unit is designed as a standardized interface or as a standardized fastening interface. For example, the energy supply unit can be detachably connected to the reflector screen, in particular to the at least one reflection element, via a so-called V-mount interface. The energy storage unit can be used, for example, to supply energy to part of the at least one lighting device or to supply energy to all of the lighting devices of the device. So that the energy storage unit can both the z. B. supply decentralized LED light sources as well as a centrally located additional light source.

By using at least one LED lighting means for the first and / or the further lighting device, an electrical battery and / or an electric accumulator can be used for the voltage supply of the LED lighting means, which has a low weight and a small volume, so that this contributes to an easily manageable device for illumination. The at least one LED lighting means can be connected or connectable to the energy storage unit, for example, via an electrical line connection, the line connection being arranged or designed in such a way that during a displacement of the reflection element between the use position and the non-use position, the line connection does not bend or bend, in particular none or a fold, preferably the line connection is oriented at least predominantly radially to a fold center of the reflector screen. Because the line connection experiences no or as few bends as possible, the risk of a line break is reduced. In particular, when the reflector screen has an umbrella-like folding movement between a use position and a non-use position, it can be advantageous if at least some, in particular all, line connections extend radially from a fold center, since in this case there is little or no risk of bending , in particular a folding of the line connections results. The reflector screen can stiffening elements, e.g. B. struts include, which supports at least one flexible reflective element at least during the use position and / or tensions. It is possible for at least one line connection to run at least in sections, in particular predominantly, in or on a stiffening element. An LED light source consists of a light-emitting diode and thus of a light-emitting semiconductor component whose electrical properties correspond to a diode.

It is possible that a control unit is provided which can be or is assigned to the at least one LED light source and by means of which at least one lighting parameter of the LED light source, in particular the light intensity and / or the color temperature and / or light color of at least one LED light source, can be changed at least in sections. Alternatively or in addition, the control unit can change the at least one lighting parameter in a time-varying manner. Also z. B. the device comprise a first group comprising at least one LED illuminant and a second group comprising at least one LED illuminant, the first and the second group being controllable independently of one another by one of the first and second groups of LED illuminants assignable or assigned control unit are. The control can relate to the lighting parameters of the respective LED lighting means and / or the assignment of at least one LED lighting means to a defined group. To control the LED lighting means, for example, each individual LED lighting means can directly or indirectly with the Control unit connected. Because the lighting parameters of the at least one LED light source can be changed, it is easy and convenient to intervene in the action of the device while illuminating a subject area, so that a targeted change or influencing of the light and shadow effects in the illuminated subject of the subject area can be reached. Here, the control unit can control both the first and the further lighting device and thus in particular influence both the central and the decentralized light generation within the three-dimensionally shaped body.

The control unit can, for example, be connected to a portable electronic terminal or to an electronic mobile device via a wired or wireless data connection for the exchange of data, in particular control data. The control unit itself can also be designed as the portable electronic terminal. For example, a smartphone, a tablet computer and / or a portable computer (e.g. laptop) can be used as the electronic terminal. A wireless connection of the electronic terminal can be implemented by means of a radio connection, in particular as a short-range radio connection (e.g. Bluetooth connection). The data connection can for example be designed as a unidirectional or bidirectional connection.

It is also advantageous, for example, if the device has a first group comprising at least one LED illuminant and a second group comprising at least one LED illuminant, the LED illuminants of the first group being different from the LED illuminants of the second group in at least one Differentiate between parameters of the light that can be emitted in each case. These parameters can e.g. B. in particular the light intensity, the color temperature and / or light color. For this purpose, the grouped LED lighting means can be designed to be variably controllable via a control unit or have an unchangeable characteristic or property or the light emitted by them that differs at least in one parameter, so that, for example, B. a first group of LED lamps emits a light in a first color temperature and a second group of LED lamps emits a light in a color temperature different from the first color temperature, and by activating or deactivating the respective group of LED lamps, an effect based on the color temperature of the illumination of the subject area can be achieved. In other words, a setting of the overall emission characteristic of the device for illuminating a subject area can be achieved through a different control of the at least two groups of LED lighting means.

The at least two groups of LED lighting means can be distributed homogeneously and / or inhomogeneously over the curved body or over the at least one reflection element. For example, in the use position of an umbrella-like reflector screen, a first group of LED lamps can be arranged or formed, in particular exclusively, in a sector section lying between two lines extending radially from a folding center of the reflector screen in the use position.

It is possible that the device for illuminating a motif area comprises a connection area arranged or formed in or on a reflector screen, in particular in or on a reflective element, preferably in or on an edge area of the light exit opening, for at least temporary connection of the connection area to an attachment element. The attachment element can be designed, for example, as a diffuser, spot attachment, screening flap, mask, film filter, glass color filter and / or honeycomb filter attachment. Here, the attachment element can cover LED lighting means at least partially on the area of the reflector screen, in particular the reflective element, facing and / or facing away from the motif area and thereby changing the lighting characteristics of the LED lighting means. A diffuser is to be understood as an aid by means of which hard direct light becomes perceptible as softer in the impression and extreme light-shadow contrasts and, if necessary, disturbing reflections are reduced. The diffuser can be formed, for example, from a semi-transparent material and can, for. B. as a, in particular white, cloth or as a flexible element in the area of the light exit opening of the three-dimensional, in particular curved, body can be connected to the reflector screen via the connection area. The connection of the attachment element with the reflector screen can preferably take place via a releasable non-positive and / or positive connection, e.g. B. this is designed as a Velcro connection. This z. B. be illuminated through the attachment element.

It can prove to be advantageous if a further illuminant is arranged on the reflector screen, in particular the further illuminant is arranged in a central area of the reflector screen, the further illuminant being designed as a halogen spotlight, as an LED illuminant and / or as a daylight illuminant. The further illuminant can be attached to the reflector screen in a detachable or non-detachable manner. The central area of the reflector screen and / or the further illuminant can be arranged, for example, on a main axis of extension of the reflector screen and / or on a straight line extending perpendicular to the main axis of extension of the reflector screen. For this purpose, z. B. the reflector screen have a recess, in particular a central opening, for receiving the further illuminant, wherein a receiving means for releasably receiving a further illuminant can be provided in the region of the recess or the central opening. The receiving means can, for. B. be designed as a ring element which, in addition to the receiving function for the further lighting means, also has a stabilizing function for at least one component of the reflector screen, in particular at least one reflection element. Thus, if necessary, struts or stiffening elements can be fastened over the ring element, in particular in an orientation extending radially away from it.

A light source designed as a daylight light source, in particular a further light source, is distinguished by emitted light with a color temperature of approx. 5300 to 6500 K and a spectral composition corresponding to natural light. The light emitted by the further illuminant reaches the motif object or the motif area through the light exit opening. The further illuminant is thus a supplementary illuminant which is provided in addition to the at least one LED illuminant and which, for example, can be attached to or removed from the device depending on the desired light effect.

It is thus possible for the further illuminant to form a further illuminant in a central area of the body having a three-dimensional shape and thus to be arranged in addition to the LED illuminants which are arranged in or on the reflector screen or reflective element and which form a first illuminant. The further lighting means, in particular LED lighting means, of the further lighting device can preferably be arranged or formed at a distance from the center of the reflector screen and thus be arranged around the centrally arranged further lighting means of the further lighting device. In particular, when the three-dimensional body is designed to be reflective at least in sections in its regions facing at least the first lighting device, it is advantageous if the further lighting device is arranged centrally. The central arrangement, in particular the arrangement of the further lighting device on an axis, in particular on a mirror axis, of the three-dimensional body optimizes the reflective property of the three-dimensional body for the light emitted from at least the further lighting device.

It can be provided, for example, that the further lighting device is arranged on a, in particular rod-shaped, carrier or includes such a carrier. The rod-shaped carrier can preferably be arranged on or parallel to an axis, in particular to an axis of symmetry, of the body having a three-dimensional shape. Here, the at least one lighting means of the further lighting device and / or an LED lighting means of the first lighting device can be arranged on the end of the rod-shaped carrier facing away from the three-dimensional body.

Because the LED lighting means is at a distance from the three-dimensional body and thus from the reflective areas of the reflection element, favorable radiation of the light emitted by the LED lighting means can be achieved. The carrier can be designed in such a way that it enables a distance between the at least one further illuminant, in particular the further LED illuminant, from the body having a three-dimensional shape or from the reflective element.

It is possible that at least one further lamp, in particular further LED lamp, is movably mounted on the carrier and / or that a carrier carrying at least one further lamp is displaceable relative to the reflector screen and / or relative to the reflection element, in particular at least a further illuminant, in particular a further LED illuminant, can be displaced along or parallel to the longitudinal axis of the carrier relative to the carrier and / or the carrier can be displaced along or parallel to its longitudinal axis relative to the reflector screen. The movable mounting or the at least temporary mobility is given in each case in the case of a construction of the device intended for the purpose of illumination, that is to say, for example, that in the case of a built-up device or in the case of a built-up arched body this in its curvature or in its three-dimensional extension remains at least essentially unchanged and only a relative displacement of at least one further illuminant, in particular an LED illuminant, to a reflector screen, in particular to a reflective element, is carried out. The fact that the reflector screen can have a different curvature in different areas makes it possible for the angle of incidence from this lamp to be reduced by the movement of the further illuminant, in particular the further LED illuminant, relative to the reflector screen or relative to the reflection element emitted light on the reflective surface of the reflector screen can be changed or varied. This leads to a change in the illumination characteristics in the subject area and thus forms a further design options for the illumination of a subject area. For example, the carrier is mounted in a carrier holder arranged on the reflector screen side or in a steady manner in relation to reflection elements, at least in sections so as to be linearly movable and / or rotatable.

The mobility of the further illuminant, in particular the further LED illuminant, relative to the carrier and / or the movability of the carrier relative to the reflector screen can be lockable at least temporarily by means of a locking means. In other words, the locking means enables an at least temporary locking of the mobility of the at least one further illuminant, in particular the at least one further LED illuminant, relative to the reflector screen or relative to the reflective element. Here, optionally or in addition, a carrier mounted movably relative to a reflection element can be designed to be lockable.

It is possible for at least one lighting means, in particular an LED lighting means, of the further lighting device to be set up to emit light radially from the carrier, in particular radially to a longitudinal axis of the carrier. A radial emission of light from the carrier means that the light in the plan view z. B. radially from the center of the light source, in particular the LED light source, starting extends away, but in the side view d. H. can be emitted along the longitudinal axis of the carrier and / or along the longitudinal axis of the reflector screen within an angular range of 10 to 170 °, preferably in an angular range of 15 to 165 °, particularly preferably in an angular range of 20 to 160 °.

It can prove to be advantageous if at least one ventilation opening is provided through which, at least when the reflector screen is in use, air between the side of the reflector screen facing a light exit opening and a side of the reflector screen facing away from the light exit opening can be passed through, in particular flow through, or through , can. Because at least one ventilation flow is arranged or formed in the area of the at least one LED light source and / or in the area of the further light source, a gas exchange and, in particular, a cooling effect can be achieved due to the air flow flowing there, so that thermal energy of the LED -Light means and / or the other light source can be transported away from this. The at least one ventilation opening can be designed in the form of a point, line, or surface, in particular slot-like ventilation openings are placed in at least one or between two adjacent reflection elements.

The at least one reflection element can, for example, be embodied at least in sections at least on the side facing the light exit opening in white, silver and / or gold. This reflective section of the reflective element designed in this way, at least in sections, enables the light hitting it to be reflected, and different light and / or shadow effects in the motif area can be achieved in a targeted manner through the respective specific color design of the reflective section. The reflective paint can be applied, for example, as a coating to the reflective section of the reflective element.

In addition to the device described herein for illuminating a subject area, the invention also relates to a reflector screen for a device described herein. The reflector screen, in particular the at least one reflection element of the reflector screen, can thus be equipped with a fastening section for the detachable or non-detachable fastening of at least one LED light source. Such a fastening portion can, for. B. be designed as a Velcro connection. Furthermore, such a reflector screen can be equipped with a fixing section which is set up to hold an energy storage unit detachably or permanently.

In addition to the device described herein for illuminating a motif area and a reflector screen described herein, the invention also relates to an insert for mounting on a device for illuminating a motif area, the device having a reflector screen comprising a reflective element, the insert at least one at least one LED illuminant , in particular a plurality of LED lighting means, comprising lighting device and the insert can be arranged in or on the reflector screen, in particular in or on the reflective element, with the at least one LED lighting means for at least partially in the mounted state of the insert in or on the reflector screen Illumination of a subject area can be used. For example, one or more LED lighting means are attached to a carrier element and / or a carrier and can be connected to a reflector screen or to a reflection element by fastening the carrier element and / or a carrier to the latter. The carrier means the element which is arranged, in particular centrally, in the three-dimensionally shaped body and which carries the further lighting device. The carrier element can carry a first lighting device, the further lighting device and / or the carrier carrying the first lighting device. In the connected state, at least one LED light source can be set up and / or aligned in such a way that its light-emitting surfaces are directed to a light exit opening of a curved body of the reflector screen and the emitted light strikes the motif area at least in sections after passing through the light exit opening. With such an insert, a reflector screen can optionally be used with or without an LED light source. The insert can, for example, have an energy storage unit for supplying energy to the at least one LED light source and / or a holder on which such an energy storage unit can be arranged at least temporarily. If the energy storage unit can be releasably fastened to the insert, it can be exchanged after the energy storage unit has been discharged. Alternatively or in addition, the energy storage unit can have an interface for connecting a charging cable.

All advantages, details, designs and / or features of the device according to the invention can be transferred or applied to the reflector screen according to the invention and / or to the insert according to the invention.
