Field of the Invention This invention relates to light output devices, particularly but not exclusively, to discrete light sources associated with a transparent substrate structure. [Prior Art] A known example of this type of light-emitting device is a so-called r LED in glass device. An example is shown in Figure i. Typically a glass sheet is used in conjunction with a transparent conductive coating (e.g., IT〇) to form an electrode. The conductive coating is patterned to form an electrode that is coupled to a semiconductor LED device. The assembly is formed by laminating the glass with lED in a thermoplastic layer (for example, polyvinyl butyral, PVB) or an organic resin layer. Applications for this type of equipment are racks, display cabinets, building facades, partitions, wall cladding, and decorative lighting fixtures. The light output device can be used for illumination of other objects for display of an image or simply for decorative purposes. In existing products, the LED is a white light source. In order to produce a color output, it is possible to provide LEDs with color filters such that each produces a color. However, the use of LEDs with color filters is inefficient due to the loss of large amounts of light. Alternatively, it is possible to use LEDs of the same type for different color outputs. However, these LEDs have different voltage and current characteristics, so these LEDs must be grouped or individually addressed. Therefore, there is a need for an efficient method of producing more than one color wheeling with low light loss and without the need for many different types of structures. 136557.d〇< 200946814 In some applications it is also necessary to have an angular phase in accordance with the obvious effect, which is also difficult to implement using the prior art. SUMMARY OF THE INVENTION According to a first aspect of the present invention, a light output device is provided, comprising: - a substrate configuration; - at least one light source within the substrate configuration and having at least a portion within the substrate configuration a light output laterally guided; and one of the passive light source elements configured to form a portion of the substrate configuration for outputting the output light in response to the light source output; wherein the at least one light source and the passive light source components Adapted to project at least two different colors in different output regions of the device, thereby producing - multi-color images, or projecting at least two different colors in different output directions, thereby producing different color effects from different viewing positions. This configuration enables the use of a single designed source of light, and the passive source elements (i.e., non-electrically driven) are used to produce different color outputs or viewing direction dependent colors. A light source is preferably used to cause a plurality of nearby passive light source elements to emit output light. The passive light source elements can include light emitting elements having an illuminating light output. In this case, the light source may comprise a uv light source or a blue-violet light source. The use of illuminating elements enables different color outputs to be provided at different locations and has illumination from a single type of source. The illuminating elements may comprise organic and inorganic luminescent and phosphorescent particles, which may be of any shape and size. 136557.doc 200946814 In an alternative configuration, the passive light source elements can include light reflecting particles. These light reflecting particles are dispersed in a random orientation or in a selected orientation. ° These reflective particles can be used as a substantial passive source. This allows a device with many effective light sources to be formed from a reduced number of active light source components. The reflective particles can also have color dependent reflection characteristics so that different colors can be output again from different parts of the device or in different directions. The reflective particles can also have a dynamically electrically controllable orientation. The orientation of the particles can also be controlled by other means, such as by a magnetic field or heat. In alternative configurations, the passive source elements can have angular dependent light output colors. For example, a dichroic mirror or layer having a grating structure can be used to selectively reflect light of a particular color and transmit light of other colors at a particular angle. In all cases, the substrate arrangement preferably includes a first substrate and a second substrate' and the passive source elements and the source of the source are between the substrates. The passive light source elements can be embedded in a resin layer between the substrates. Preferably, the device has an electrode configuration that is provided within the substrate configuration and includes at least a translucent electrode, wherein the at least one light source (preferably - the array of light sources) is electrically driven by the electrodes. Each light source can include a LED device or a group of LED devices. The present invention also provides a method of providing a light output, comprising: generating a light source output from at least one light source in a substrate arrangement of a light output device, the light source output being at least partially laterally guided within the substrate configuration B6557 .doc -6-200946814; and - utilizing the light source output to illuminate one of the passive light source elements in the substrate arrangement such that the at least one light source and the passive light source elements project at least two different output regions of the device The output light of different colors, thereby generating a multi-color image, or projecting output light having at least two different colors in different output directions, thereby generating different color effects from different viewing positions.

Between the glass plates are (semi)transparent electrodes "and 3b (for example formed using IT0 or thin wires), and an LED 4 connected to the transparent electrodes 3a and 3b. - Thermoplastic layer 5 is provided Between glass plates 1 and 2 (for example, pVB or UV curable resin). When a transparent electrode is used, it is not visible to the viewer, and its etc. does not introduce non-uniformity to the light output. Preferably, the actual use of the eight-hearted W #礅发罝's electrodes are imperceptible to the viewer. If the conductor configuration does not introduce significant light transmission changes (for example, because it is not patterned) 'Or because the pattern is invisible, one brother) shell! greater than or 4 to 5% transparency, the foot U makes the system transparent. 7〇0/ , Φ Λ Preferably, the transparency is greater than ° Good is 90%, and even the best is 99. If you talk about the dip diagram or the I conductor configuration (for example, because of the use of thin wires), the transparency is better 136557.doc 200946814 More than 8〇%, more preferably 90%, but optimally greater than 99%. Extremely - transparent material such as IT0 Or, the electrodes == a transparent material (such as copper), but which is sufficiently thin to make the electrodes invisible in normal use. Examples of suitable materials are disclosed in US-A-5 281 351 A particularly opaque conductive material may be a conductive ink deposited by m-screen printing or ink jet printing, as this allows the conductor arrangement to be deposited in a more economical manner. The glass sheets typically have a hl mm to The thickness between the electrodes is typically from 0.01 mm to 3 mm, for example about 15 mm. The thermoplastic layer has a thickness of from 5 mm to 2 mm, and the range of resistance of the electrodes is 丨Ohm/square to 8 〇 ohm/square, or 1 ohm/square to 5 〇 ohm 7 square, or more preferably 2 ohm/square to 20 ohm/square, or 10 ohm/square to 30 ohm/square. a light output device, wherein the light source in the structure in which the substrate is disposed has a light output that is substantially laterally guided in the substrate configuration, the light system is used to illuminate a passive light source element that forms part of the structure of the substrate configuration one Arranging, thereby projecting output light. This enables different illumination effects to be implemented based on the passive light source elements. The passive light source elements are not electrically driven to emit light, but instead redirect or convert light from the source, for example By 'reflecting, refracting/diffusing or exhibiting emission such as illuminating and illuminating light. Figure 3 shows a first example of the light output device of the present invention. The substrate configuration again includes a first substrate 1 and a second substrate 2 And one of the arrays [Fig. 136557.doc 200946814 3 shows only one of the cross sections, and a 2x2 array is shown in plan view at the bottom of FIG. 3). This electrode configuration is not shown to make the figures simpler. The light source 4 is in the configuration of the substrate configuration as in the example of Figure 2, but has a light output that is generally laterally oriented within the substrate configuration. This can be achieved by providing a side-emitting LED (for example, a wafer having a reflective top smear) whereby light can only escape laterally. One configuration of the passive light source component 6 is provided within the structure of the substrate configuration. In the example of Fig. 3, the passive light source elements 6 comprise illuminating elements' and their responses responsive to the excitation of the LED output to emit light. For example, the LED includes a UV light source or a blue-violet light source, and the light emitting elements can provide a desired light output, which can be white light or light having any other desired color. The light-emitting elements 6 may be dispersed in a resin 5 for laminating the substrates. In the example of Figure 4, the light-emitting elements comprise luminescent ceramic elements, and as shown in the lower portion of Figure 4, a regular pattern can be provided. This configuration can be used to provide different color outputs from the top and bottom surfaces of the device. This can be accomplished by mounting the light-emitting elements against two substrates, preferably one set of light-emitting elements being provided via a substrate, and the other set of light-emitting elements providing an output via another substrate. In the simplest case, the light-emitting elements 6 have only one color, so that if portions of the light output from the (active) light source are also escaping from the substrate configuration, the device generally has two output colors. The active light 136557.doc 200946814 source 4 causes a color output and the passive light sources 6 cause another color output. As shown in Fig. 5, a decorative effect can be produced by forming the luminescent particles into a desired pattern, and Fig. 5 shows two passive light source elements 6a and 6b having different luminescent colors. Fig. 6 shows the decorative effect produced by forming a light-emitting region having a desired pattern, and it is also possible to reuse materials which emit different colors. In the above examples, the "passive" light sources are light-emitting elements. However, several of these benefits can be obtained based on reflection or diffraction. Fig. 7 shows light-reflecting particles 1 such as sheets or illuminating sheets, which are again embedded in the resin layer and illuminate the LEd 4 using one side. In Figure 7, the particles 10 have a random orientation. Figure 8 shows a method of permanently fixing the orientation of the particles as shown in Figure 8a by the curing process. This random orientation provides an angular dependent viewing effect as shown in Figure 9, and this is considered to be required for some decorative lighting applications. The left image in Figure 9 shows the twist (normal) viewing direction. The intermediate image shows a 35 degree viewing angle and the right image shows a 7 degree viewing angle. At these different angles, the viewer can experience mirror reflections from light from different particles that can be colored. In the same way, various diffractive colors at different angles can be experienced from the diffractive particles. Instead of using a random orientation, the microparticles can be oriented by external stimuli such as an electric or magnetic field during the coagulation step of the figure. The particles 1〇 may be specularly reflective, diffusely reflective, or a combination thereof. They may also be partially transparent, such as a thin layer of aluminum (less than 136557.doc -10·200946814 for partial reflectivity and partial selection. Color effects may also utilize reflection' by utilizing as utilized in the description below The layer having the grating structure and the color-dependent reflection characteristics of the multilayer structure or the sterol type sheet are implemented. The particles can be selected to reflect only one color and are transparent to the other colors. Therefore, the particles are used as color choppers.

In Fig. 1 (and Figs. 12 and 13), R represents red light, G represents green light, and B represents blue light. The sheets can be aligned using external stimuli such as electric fields and magnetic fields. By applying a field in different directions, the desired orientation of one of the sheets can be induced. The direction of the sheets can be fixed after polymerization of the resin. Figure 11 shows that the reflective particles do not have to be fixed but are movable. In this case, a liquid is used instead of the _ laminate. In this way, the sheets produce a dynamic illuminating effect due to their reorientation. It is important for this to be that the sheets have a density that is comparable to the density of the liquid. Density matching can be achieved by using a thin liquid of a metal having a non-metallic layer (e.g., a polymer). The orientation of the sheets can be achieved by the applied electric field and thus the dynamic effects are achieved. The Out:: Polar Configuration display is used to control the orientation of the particles 10 to change the output direction as indicated by arrow 12. It is also possible to use the spacers in which the sheets are interspersed. It is also possible to make the sheets depend on the driving characteristics to achieve different sheet orientations. 4 Drive characteristics can vary with the device Figure 11 shows a possible electrode for an in-plane electrode with alternating polarity 136557.doc 11 200946814 Configuration 'Although other electrode configurations can also be used. The above examples utilize illumination or reflection to provide a "passive" source output. - An alternative is to use a periodic structure with angular dependent wavelength reflection and diffraction effects. This can be used to provide different color outputs at different viewing locations, for example, as shown in Figure 9 for different viewing positions. The figure shows how the diffraction can be used to lighten the light from the outside of the substrate. The structure 16 is diffracted to direct different colors in different output directions. The structure 16 is provided on the substrate 1. On top. Various fabrication methods can be used to fabricate such structures, including molding, embossing, lithography, and holography. It is also possible to embed a sheet of the desired structure in the LED. The top of the substrate of the glass structure. The wavelength-angle dependent property can be adjusted by changing the size of the structures (e.g., pitch) or the material properties of the structures (e.g., refractive index). The structure i6 can be implemented as - or Multilayer structure, cholesteric material and photonic crystal structure, etc., provide angular reflection wavelength reflection effect. The multilayer structure has the advantages of low absorption, long life, temperature and light stability, and is easy to manufacture. The plurality of layers are coated with a substrate to produce a multilayer structure. The change in refractive index in the layer induces a reflection band. The position of the reflection band exhibits an angular dependence. A polymer film is formed by extrusion molding. In a similar manner, a cholesteric liquid crystal sheet can also be used for this purpose. These films are made of so-called self-assembled liquid crystals, which can be crosslinked polymers or glasses. Linear polymers. By controlling the thickness of individual layers and their refractive indices, the long-angle dependent properties of the wave 136557.doc 200946814 can be adjusted. In the case of 3D photonic crystals, periodic 3D structures can be used. The structure can be combined with an optical outcoupling structure to embed light from the LED in the glass light output device. Figure 13 shows the use of a dichroic mirror (as a wavelength waver) 1 $, 2 〇 and an optical outer structure or The structures 16 implemented as a layer in the form of a grating or diffuser. The LED embedded in the glass light-emitting device may be completely covered by the structures or layers (Fig. 14A), partially covered (Fig. 14B), or by wavelength-angle Patterned according to the structure (Fig. 14C). For example, the structures can be used to form a patterned trademark or the word. The structures or layers 16 can be positioned on the outer side of the substrate embedded in the substrate device (Fig. 15A). Within (Fig. 15B) or both (Fig. 15C). A scratch resistant material or an additional coating may be used. For example, the structures may be made of a sol gel material. The structures and layers may be included in the LED embedded in the glass. Internally, the angle-dependent illuminating effect is used to enhance the decorative appearance of the panels. While other applications such as furniture and other decorative items are possible, the present invention is particularly advantageous for signboards, decorative lighting such as lamps, windows, architectural glass, and security. In the above context, the term multi-color image means an output from a device comprising at least two different colors, the at least two different colors being substantially independently provided at different locations on the output surface such that the at least two The color can be individually identified by the viewer at different locations on the output surface. Similarly, different color effects from different viewing positions mean a different total 136557.doc -13- 200946814 body color impression by the viewer Seen in different viewing positions, the detailed example above uses an LED light source, but the present invention is applicable to other light sources. Various other possibilities are within the scope of the various aspects of the invention as defined by the appended claims. It will be apparent to those skilled in the art that various other modifications are possible.
