An example of a suitable material is disclosed in US Pat. No. 5,821,541. The present invention provides an LED configuration embedded in a light transmissive substrate and for generating electrical power to operate the LED configuration. An integrated system for a solar cell. Figure 3 illustrates an example of a light output device of the present invention. A substrate arrangement 1 〇 includes first and second transparent substrates and a transparent laminate layer between the substrates ( As shown in Fig. 2), a plurality of light source devices 12 are integrated into the laminated layer. The light source devices 12 include one or more LEDs 4 of the type shown in Fig. 2. Therefore, the 'light source configuration is as shown in Figs.

Can be The battery configuration 15 is charged by the at least one photovoltaic cell and is used to drive the light source device 12. The solar cell or the solar cells are configured to be at least translucent. Suitable solar cells are commercially available from XsunX (trademark The company uses a transparent conductive oxide as a connector and uses an amorphous germanium photosensitive cell. An amorphous one having an annealed 13198I.doc 200920985(R) (ie, polycrystalline germanium) is disclosed in US Pat. No. 6,180,871. A similar configuration of cells. There have been many studies on solar cells with good transparency to the visible spectrum. Another example is designed to transmit visible light while converting ultraviolet radiation to electricity. Another example of a transparent solar cell has been proposed by Toshiba Corporation of Japan, which relies on a titanium dioxide nanocrystal coated with a dye. When illuminated by light, the dye is injected into the semiconducting titanium to generate electricity. This is an improved version of the known Graetzel battery. Graetzel batteries have improved transparency over conventional solar panels. However, the early Graetzel design relied on a liquid electrolyte to supplement the dye with electrons. Designed by Toshiba Corporation of Japan, the liquid electrolyte is encapsulated in a durable solids that can withstand temperatures up to i 2 〇 °C in a "crosslinking" gel. These examples are merely to demonstrate that many different solar cells can be incorporated into the device of the present invention' and that such cells can have different degrees of transparency in the visible spectrum. The solar cells used should be selected depending on the efficiency of converting incident light into electricity and the degree of transparency desired. The apparatus of the present invention is made by bonding an LED and a solar cell to a glass substrate 1 having a patterned transparent conductor 3. The second glass substrate 2 is laminated to the first glass substrate, wherein the LEd and the solar cell are embedded in the laminated layer 5. In the example shown, the LEDs are arranged in a parallel branch' each of the branches has three LEDs connected in series. In this case, the total voltage is about 9 to 1 〇 V plus a voltage drop across the conductive coating that may be a few volts. The power generated by the solar battery 13 is converted by a power converter 14 into a voltage (for example, I] V) used to charge the battery and then drive the LEDs for use in 131981.doc •10-200920985. ° In the example shown, a rechargeable battery array is provided, such as ten 1.2 V nickel-hydrogen (NiMH) batteries 15 in series. A light sensor 16 connected to the power converter 控制 controls whether the power converter feeds the batteries (during the day) to charge the battery, or whether the batteries supply power to the LEDs (at night) for Provide a light output.

The device of the present invention can be applied to many different applications, for example, road number w $ road lighting, building roof lighting, garden lighting, and advertising signs. The road is marked with special features; t problem. LED lighting is increasingly being used for the reason that these standards usually require an external power supply to operate (4). When the two cable-wound wires are used as the external cable connection for the lighting system, the reliability of the system is affected by unfavorable weather conditions. By providing solar cells and LEDs in a glass: structure, the reliability will not be subject to conditions and no external power connections are required, and the installation of the device is more free. • Another application to Guanzhuang has a glass ceiling. Building area 1 gentleman's atrium, hotel lobby, walkway and shopping mall. The traditional method of illuminating such areas is nothing more than a pole mount or a suspended downlight. This issue: The system provides more attractive functional lighting. The system of the present invention can be used to make thinner units (including backlights) of the lighting system and this provides 131981.doc 200920985 for more attractive lighting solutions used in urban renewal meters, for example, painting. Even when using a glass, allowing 4c, too / /, slabs (such as viewing the night sky), the present invention also has the decorative ceiling effect to be added. In the -glass ceiling application, there is no need to be unsightly. Trunking or other galvanic piping is required. Other applications include emergency lighting systems, ^ U is the system that can tolerate total power outages. Beta can also be used to temporarily illuminate the system, in ',,, For example, portable lighting for expositions, exhibitions or markets. The above examples have been shown to be small [5 car engraved, beta soap column light source. However, it should be understood

The dry multi-LED device dares to enter a large glass plate. A typical distance between the LEDs is J two i cm to 1 〇 cm ′, for example, about 3 cm. The above example allows each light source to also include a single LED or multiple LEDs. A glass substrate is used, but a plastic substrate can of course be used. The /ED array and the required control circuitry can be combined into an integrated device or such a low resistance interconnect wire connection. In the description and request items,? The components have been rendered substantially transparent. This means that at least 50% of the energy of the visible spectrum is transmitted, and preferably at least 75% or 85%. The term transparent refers to "transparency", and the transparent component can be translucent (i.e., with some image distortion). Those skilled in the art will appreciate a variety of modifications. [Simplified Schematic] Figure 1 shows schematically glass.
