DETAILED DESCRIPTION OF EMBODIMENTS Before describing several embodiments of the device, it is to be understood that the device is not limited to the details of construction or process steps set forth in the following description. It will be apparent to those skilled in the art having the benefit of the present disclosure that the device is capable of other embodiments and of being practiced or being carried out in various ways. The present disclosure may be better understood in view of the following explanations: As used herein the term “optical display device” may refer to electrically operated optical apparatus that is capable of providing an observer with a perception of a real-life sky when gazing into an output aperture of the device. The device creates a virtual sky scene. The virtual sky scene may have a perception of infinite depth (as for a real-life sky). The device may be dimensioned such that it is suitable for attachment to a ceiling or wall (e.g. a side wall, including a window) of an interior or a building, e.g., it is less than 1.5 meters or 2 meters or 3 meters in lateral and / or longitudinal dimension; it may be greater than 0.20 meters in lateral and / or longitudinal dimension; it may have a depth of less than 0.5 meters. The output aperture may extend over a substantial amount of the lateral and / or longitudinal dimension of the device, e.g. within a frame that frames the output aperture that has a peripheral width of 0.5 - 5 cm in said lateral and / or longitudinal dimension. The device may recreate characteristics of said real-life sky. As used herein, the term “characteristics of a real-life sky” may refer to any optical characteristic of the real-life sky that is capable of measurement and replication in output light from the optical display device. A characteristic may include one or more of the following: a real-life colour of a real-life sky light component; a real-life colour of a real-life sun light component; a real-life intensity of a real-life sky light component; a real-life intensity of a real life sun light component, and; an angle of the real life sun light component. As used herein, the term “intensity” may refer to any quantity related to a brightness perceived by a user, e.g., one or more of a: radiant intensity, measured in watts per steradian (W / sr); luminous intensity, a measured in lumens per steradian (Im / sr), or candela (cd); Irradiance; luminous power, or luminous flux) measured in lumen. As used herein, the term “colour” may refer to a colour measured by a suitable colour system which may enable digital representation, e.g., colour correlated temperature (OCT) or a colour space, including RGB, sRGB, a Pantone collection, CIELAB or CIEXYZ etc. As used herein, the term “real-life colour” may refer to a colour as measured by a colour system, which is assigned, e.g., as an average or other numerical approximation, to an object. The object can be the sun or the sky. Said colour of the object may be measured without interference (including substantial interference) from other objects in the sky scene. As used herein the term “real-life sky” may refer to a sky view that an observer observes when gazing through a window (e.g., in a side wall or ceiling) of a structure or otherwise from the ground. The portion of the sky view observed typically comprises the sun and surrounding sky, but in some cases, it may only comprise only the former or the latter. Hence a real-life sky may include a real-life sky light component and / or may include a real-life sun light component. The real-life sun light component may include a circular (including substantially circular) yellow / white sun (e.g., a warm colour) and includes direct light. The real-life sky light component includes indirect light from the sun and is absent the real-life sun light component. The real-life sky light component may include: a clear sky component, e.g., a blue / cold colour, and / or; cloud component e.g., a white / grey colour. The clear sky component may surround (including partially or fully) the circular sun. The cloud component can surround and extend over (including partially or fully) the sun. As used herein “warm” in respect of the sun light component may refer to a yellow and / or white colour. The CCT may be 3000 - 5000k. As used herein “cold” in respect of the sky light component may refer to a blue and / or white colour. The CCT may be 5000 - 10000K. As used herein the term “perception of infinite depth” may refer to a depth of an object (e.g., the sky and / or sun) in three dimensions being perceived as infinitely far away from an observer with stereopsis (e.g., binocular vision). A perception of infinite depth may be provided by one or more of: binocular convergence; motion parallax, and; accommodation visual depth perception cues, e.g., no conflict exists between these visual perception cues. The condition of infinite depth may be determined based on gaze vectors of the eyes of an observer having the same and / or a similar alignment when looking into the device as for looking at the sky and / or sun in the real-life sky. The condition of infinite depth based on motion parallax may be determined based on the image of the sun appearing to be projected from the same location, e.g., moving, as an observer moves laterally and / or longitudinally across the output aperture. An observer user may maintain the same gaze vector associated with infinite depth during said motion. As used herein the term “sky scene” or “virtual sky scene” may refer to a scene comprising a virtual representation that an observer observes when gazing through the output aperture of the optical display device. A sky scene may include a virtual sky light component and / or may include a virtual sun light component as defined herein. The sky scene may include a circular (including substantially circular) sun coloured image of the sun light component. The sun may be surrounded (including partially or fully) and / or overlapped (including partially or fully) by the sky light component. Alternatively, the sky scene may include the sky light component and no sunlight component. As used herein the term “perception of a sky scene” may refer an observer perceiving a sky scene as being present in the real world, based on the construction by the device of a virtual sky scene that is sufficiently representative, e.g., in terms of chromatic and spatial distribution of light, to present as in the real-life sky. As used herein the term “artificial sky light component” or “diffuse light component” may refer to artificial light that is representative of the real-life sky light component (e.g., absent the real-life sun light component), which can include a clear sky component and / or a cloud component (where both components are present the average component may be used) during daylight, sunset or sunrise. It may be representative of the real-life sky light component in respect of one or more of: colour, e.g., as defined by a CCT (e.g., 5000 - 10000K), the colour may only be blue or optionally white, e.g. to exclude sunrise / sunset conditions; diffusivity; luminance profile or intensity; other suitable parameter, and; a variance of any of the aforesaid over an output aperture of the device. The diffuse light component may be uniform such that is does not vary by more than 10% or 20% or 30% or 40% over the entire output aperture, e.g., in terms of one or more of: colour; luminance (e.g. in candelas per square meter (cd / m2), including luminance profile); intensity, and other suitable parameter. More particularly, said one or more parameters may be uniform to the extent where they do not vary by more than 10% or 20% or 30% or 40% for any given circular area on the output aperture of 10 mm diameter over at least 90% of the output aperture. In a particular example, the diffuse light is propagated over a HWHM solid angle that is at least 4 times larger or 9 times larger or 16 times larger than for the subtending HWHM solid angle of the sun light measured in Sr. The artificial sky light component may have a lumen of 3000 - 10.000, or 4000 - 7000. The diffuse sky light component in the output light may have a Lambertian distribution. A Lambertian distribution may refer to a type of diffuse reflection or scattering of light from a surface. The Lambertian model assumes that a surface reflects light uniformly in all directions. This means that the intensity of the reflected light is proportional to the cosine of the angle between the incoming light direction and the surface normal. As used herein the term “sun light component” or “direct light component” may refer to artificial light that is representative of the real-life sun light component. It may be representative of the real-life sun light component in respect of one or more of: colour, e.g. as defined by a CCT (e.g. 3000 - 5000k, which is less than that of the sky light component); divergence (e.g. an angle of divergence of the light rays may be no more than 5 or 2 or 1 or 0.5 degrees relative each other); luminance profile or intensity; other suitable parameter, and; a variance of any of the aforesaid over an output aperture of the device. In a particular example, the luminance profile of the sun light may have a narrow peak in the angular distribution around the direction of propagation which is subtended by a HWHM solid angle smaller than 0.2 sr or 0.3 sr. The sun light component may be projected uniformly over the output aperture, e.g., such that an average direction of propagation within a circle of diameter 10 mm at any position over the output aperture does not vary in angle by more than 2 or 5 or 10%. The sun light component may present to a user when looking into the device, as a circular disc positioned at infinity. As used herein the term “collimated light” may refer to light that has been processed by a collimated light generation system, which may form the sun light component. As used herein the term “output aperture” may refer to a viewing window of the device into which an observer can gaze. The output aperture may be 0.3 - 2 m x 0.3 - 2 m. The output aperture outputs the output light which is generated by the device. The output aperture may include a transparent member or a void instead of such a member. The output aperture may include a frame that frames the transparent member. As used herein the term “transparent member” may refer to a medium through which the output light is projected. The transparent member may be planar. The transparent member may be formed of glass or plastic or other suitable material. As used herein the term “reflective member” may refer to an object that is capable of reflecting an image by specular reflection. It can include a member with any surface in which the texture or roughness of the surface is smaller (smoother) than the wavelength of the incident light. It may include surfaces formed of one or more of the following reflective materials: metals; metal oxides, and; dielectric materials. Examples of which include silver, aluminium, a titanium oxide based material including titanium dioxide or titanium trioxide. Any of the aforementioned may be applied as a thin coating on a glass carrier. As used herein the term “a reflective and partially transmissive member” or “partially reflective member” may refer to a reflective member as defined above, which is additionally configured to transmit therethrough a portion of light which is not reflected. An example of which is a member formed with a lesser thickness than for the aforedescribed reflective material. The transmissivity maybe less than 50% or 30% for incident electromagnetic radiation. The thickness of the reflective material may be any one or the following: less than 700 nm; less than 100 nm; less than 50 nm, and; less than 5 nm, with any of the aforementioned maximum thickness ranges implemented with a minimum thickness of 1 nm. As used herein the term “output light generation system” may refer to a single (or a distributed system) capable of generating the output light.

[General system description] Referring to figure 1, the system 2 at a customer location comprises: lighting control devices 4 for control of light 6, and electrical circuitry 8 for control of various characteristics of the light 6, as will be discussed. The electrical circuitry 8 may be distributed on one or more of: one or more of the lighting control devices 4; a server system (not illustrated); an external device (not illustrated). The lighting control device 4 comprises the electrical circuitry 8 for control of operation of the lighting control device 4 based on a device parameter (as will be discussed) stored on electronic memory (not illustrated) of the electrical circuitry 8. In variant embodiments, which are not illustrated: the system comprises a single or other number of devices, in the instance of multiple devices, said devices can be arranged in series with each other as a combinatory assembly or at various locations on a room / through a building; each device comprises its own dedicated electrical circuitry rather than the electrical circuitry controlling multiple devices. Referring to figure 2, a general lighting control device 4 is arranged as an optical display device comprises: an output light generation system 10 for generation of the output light 6; an output aperture 12 for of the output light 6, and the electrical circuitry 8 for control of the output light generation system 10. The output light 6 is generally projected in the depth directed 104, which is orthogonal to the plane of the output aperture 12. [First example] Referring to figure 3 a first device example of the device 4, which incorporates features and associated variants of the aforedescribed general device 4, comprises the output light generation system 10 arranged as a diffuse light generation system 14. In the first example, the output light generation system 10 does not comprise a collimated light generation system, hence the output light 6 includes only a sky light component 16. Referring to figure 4, in further detail the first example comprises the diffuse light generation system 14 arranged with a waveguide 18 and a light source 20. The output aperture 12 comprises a transparent member 22 and is defined by a frame 24. The device 4 includes a housing 26 to house said components. The output aperture 12 is planar and is aligned in the longitudinal direction 100 and lateral direction 102. A thickness of the device 4 is arranged in the depth direction 104. The frame 26 surrounds the transparent member 22 and gives an impression of a real-life window or skylight frame. The light source 20 emits light in the longitudinal direction 100 into a side face of the waveguide 18. The waveguide 18 includes redirecting features (not illustrated) though its section which scatter the internally reflected light from the light source 20. The light emitted from the light source 20 is retained within the waveguide 18 by total internal reflection until it encounters a redirecting features and is scattered enabling it to exit the waveguide 18 as the diffuse sky light component 18. In variant embodiments, which are not illustrated: the diffuse light generation system is alternatively configured; uncoupling features are on an edge of the waveguide, which are configured to decouple the light therefrom; the diffuse light generation system comprises a backlit rather than an edge lit arrangement. The transparent member 22 includes an interior face 36 that faces into the device 4, and into the output light generation system 10 and an exterior face 38 that faces away from the device 4 (which an observer gazes directly into) and a side face 40 extends between the interior face 36 and the exterior face 38 and around a periphery of the interior face 36 exterior face 38. The transparent member 22 is aligned in the longitudinal direction 100 and lateral direction 102. The frame 24 includes: an interior side face 42; an outer side face 44; a top face 46, and; a bottom face 48. The top face 46 is arranged at a greater depth in the depth direction 104 than the bottom face 48. [Second example] Referring to figures 5 and 6 a second device example includes the features of the first example and associated variants, but with the output light generation system 10 additionally implementing a collimated light generation system 28 to generate a sun light component 30. The collimated light generation system 28 includes a light source 32 and a collimating system 34. The light source 32 projects a light beam (not illustrated) to the collimating system 34, which processes the received light beam to output collimated light which subsequently becomes the sun light component 30. The light source 32 is implemented as a 2-dimmensional array of LEDs, which can be arranged on a common substrate (not illustrated) that extends in the lateral direction 100 and the longitudinal direction 102. The collimating system 34 is implemented as a 2-dimmensional array of lenses (not illustrated), each of which being associated with an LED. A homogenising element (not illustrated) may optionally be implemented subsequent to the collimating system 34 to remove stray light which may be introduced by the collimating system 34 and / or the light source 32, e.g. as an absorbent honeycomb through which the collimated light passes. In variant embodiments, the collimated light generation system is alternatively implemented, including: as a single or 1-dimensional array of light sources, which are expanded over the output aperture, e.g. by using an expansion system, which can include one or more reflective members and prism sheets, and; the collimating system is alternatively implemented as parabolic reflectors or other collimating systems; the collimated light generation system is implemented as a laser light source, which may obviate the collimating system. The collimated light generation system may also be separate from the diffuse light generation system, e.g., as a spotlight. In variant embodiments, which are not illustrated, the lighting control device is alternatively configured for example: the lighting control device is arranged as an light control arrangement which comprises apertures that are controllable to let natural light pass, e.g. an automated shade / blind system with the apparatus controlled by the electrical circuitry; an other electronic device in communication with an optical display device to control its operation, e.g. computer module, said control may be to control groupings of said optical display devices, or a sensor system to sense light in a room. [Configuring of light control device] Referring to figure 7 a system 70 for configuring the lighting control device 4 is illustrated. The lighting control device 4 may implement the features of any preceding embodiment (e.g. the first or second device example of the optical display device) of another embodiment disclosed herein. The system 70 comprises a customer electronic device 72 as defined herein; a device parameter configuring computer system 74; a lighting control device configuring computer system 76, all of which communicate with each other over a computer network 78 as defined herein. As used herein the term “computer system” may refer to a server system as defined herein. It may include electrical circuitry as defined herein in, e.g. one or more processes and electronic memory. The computer system may by represented as one or more modules (e.g. a software module) each providing a function. The customer may for example be one or more of: a purchaser of the lighting control device; the end user (e.g. including an owner / leaser of the installation building); a specifier (e.g. including an interior designer or architect) who may purchase / install the lighting control device on behalf of the end user. The customer electronic device 72 is typically a mobile phone or other personal computer system. The configuration parameter is typically determined by an application (e.g. a mobile or web application) which may be supplied by one or more of the: manufacturer; configurer; distributor, e.g. from a computer system thereof. In variant embodiments, which are not illustrated, the system is alternatively implemented, for example any of the computer systems may be integrated or otherwise distributed e.g. as a cloud based computer system, for example, the device parameter configuring computer system and the lighting control device configuring computer system may be implemented on the same computer system. Referring to figure 8, a method of configuring the lighting control device 4 is illustrated, which comprises: Block 120: receiving a purchase request for the lighting control device 4, e.g. from the customer electronic device 72 or another electronic device (not illustrated) implementing the application (or a different application). The purchase request may comprise the transmission (e.g. implemented by the application) of electronic information from the customer electronic device to a computer system of a retailing entity, e.g. one or more of the: manufacturer; configurer; distributor. Block 122: receiving from the customer electronic device 72, a configuration parameter on the device parameter configuring computer system 74. The receipt of the purchase request on the computer system may trigger the computer system to send a request to the customer electronic device 72 for the configuration parameter. Alternatively, the request may be initiated by an application running on the customer electronic device 72, or by another suitable arrangement. The application of the customer electronic device 72 receives an input via a user interface from the customer to determine the configuration parameter. For example, the input may be a selection of: location information, e.g. one or more of: a point on a map; coordinates; and address including Zip / Post Code; actual time zone; longitude and latitude; a circadian rhythm of a property of light at the customer location; other like information. In other examples, the selection includes: light information as defined herein; operational information as defined herein, or; other like information. The application generates the configuration parameter as an identifier, which is associated with said input. For example, the identifier comprises an alpha and / or numeric string which encodes / is associated with the input selection. In variant embodiments: the configuration parameter is alternatively configured, e.g. it comprises the input selection directly, e.g. as one or more payloads, including the location specific information rather than an identifier etc; the configuration parameter may be entered by the customer absent a request for the configuration parameter or a purchase request. The customer electronic device is typically located at the customer location, which is remote from the configuring location. Block 124: obtaining at least one device parameter of the lighting control device based on the configuration parameter. This step may comprise look-up with a database of the or each device parameter based on the received configuration parameter. Other models may be implemented, e.g. a numerical calculation based on a mathematical function relating the device parameter to the configuration parameter. The or each device parameter may comprise one or more of: light information as defined herein; operational information as defined herein, or; other suitable parameters. Block 124 is executed by the device parameter configuring computer system 74, which may be located at one or more of: a manufacturing location (e.g. where the lighting control device 4 is fully or partially assembled); a configuring location (e.g. where the lighting control device 4 is fully or partially configured according to block 126); a distributor location (e.g. where the device is sold and / or shipped); other location including as a cloud based distributed computing system typically other than that of the customer location. Block 126: implementing configuring of the lighting control device 4, whilst the lighting control device is arranged at a configuring location (e.g. the manufacturing location or a distributor location or location other than the customer location) by: A) storing the at least one device parameter on non-transient electronic memory of the electrical circuitry of the lighting control device. For example, the or each device parameter may be transferred from the lighting control device configuring computer system 76 over a computer network to the electrical circuitry 8 of the lighting control device 4. The computer network may comprise a wireless network, and / or the electrical circuitry 8 of the lighting control device 4 may implement wireless energy transmission arrangement. In this way the lighting control device 4 may remain in packaging material during said transfer of the device parameter. B) associating the at least one device parameter with an identifier stored on non-transient electronic memory of the electrical circuitry of the lighting control device. For example, the or each device parameters defined for association with the lighting control device 4 at block 124, are assigned to a unique identifier of the lighting control device 4. The identifier is both stored on the electrical circuitry 8 of the lighting control device 4 and on a database of the lighting control device configuring computer system 76. The database associates the or each device parameter with the identifier, e.g. as a look-up arrangement. Once the lighting control device 4 is connected to a computer network (e.g. at the customer location), the electrical circuitry 8 of the lighting control device 4 transfers the identifier to the lighting control device configuring computer system 76 (e.g. after receiving a request from said computer system). The lighting control device configuring computer system 76 uses he identifier to look-up the or each device parameter from the database, and transfers the or each device parameter over the computer network to for storage on non-transient electronic memory of the electrical circuitry 8 of the lighting control device 4. In this way the lighting control device 4 may remain in packaging material during the configuring. Block 128: transfer of the configured lighting control device 4 to the customer location (e.g. subsequent to configuring of the lighting control device). This step may comprise computer implemented steps, which are executed by a computer system of the system 70, e.g. a shipping computer system (not illustrated), for providing shipping information to a shipper (e.g. a logistics company). The shipping information may comprise location information of the customer location and / or a consignment (e.g. the lighting control device 4) to the shipper. The step may also comprise the physical act of shipping the configured lighting control device 4. In variant embodiments, blocks may be executed in other orders, or some blocks may be omitted: for example: blocks 120 and / or block 128 may be omitted; block 120 may be executed after any step; block 124 and block 126 may be executed after shipping. [Configuring of via application] Referring to figure 9, a user interface 140 (e.g. a touch display) of the customer electronic device 72 comprises a graphical output of the application. Referring to figure 10, a method of configuring the lighting control device 4 is illustrated, which comprises: Block 130: supply of input related to the configuration parameter, e.g. via the user interface of the application executed on the customer electronic device 72. In an example the input comprises location information that is associated with a geographical location of the customer location, e.g. one or more of: a point on a map is selected; coordinates are entered; a time zone is entered. Alternatively: the location may be automatically obtained from a GPS of the customer electronic device 72; or a default location may be assumed. Block 132: the application provides (e.g. via the user interface) a graphical profile 142 as shown in figure 9, which comprises a 2-dimensional curve of a property of output light from the output light generation system 10 of the optical display device 4 that is to be configured remotely. In the example the property of the output light is colour in OCT vs. time for a 24-hr cycle (e.g. a day, circadian rhythm). In other examples other properties of the output light may be represented graphical in this way, e.g. intensity, including in lumen, or melanopic ratio, or other colour representations etc. The graphical profile 142 is determined based on the location information provided at block 130, e.g. in the example, the OCT profile is determined based on empirical data associated with the customer location identifier from the location information. For example, the identifier is sent via the application over the computer network to a server system of the configurer, with the graphical profile being returned to the application as information for display on the user interface. Alternately a default profile is used for the property of output light from the output light generation system 10 of the optical display device 4. Block 134: the application is configured to receive a user input to adjust the graphical profile. For example, the time and the property of output light may be displayed by the user interface as nodes that can be selected and moved to change the graphical profile, e.g. as drag and drop functionality. Other adjustment may alternately be implemented, e.g. by entering of values manually. Block 136: the application implements the adjusted graphical profile as the or each configuration parameter, e.g. for the configuring method associated with figure 8. The application may also be arranged to control the associated property of the output light of the lighting control device directly, e.g. once said device is installed at the customer location, e.g. via Block 132 and Block 134 which are implemented as above with Block 136 alternatively implemented to control the parameter. By using the same application for pre-shipping configuration and post installation configuration, the user may be familiar with the same user interface.
