Title: LEDoS projection system

Description:
CROSS REFERENCE TO RELATED APPLICATION 
     This application claims priority to U.S. provisional application No. 61/795,336, filed on Oct. 15, 2012 and entitled: “Intelligent Traffic Light (iTL) with LEDoS Projection System.” The entirety of this provisional application is incorporated herein by reference. 
    
    
     TECHNICAL FIELD 
     This disclosure generally relates to a light emitting diode on silicone (LEDoS) projection system, e.g., multi-color LEDoS prism-based projection system and related embodiments. 
     BACKGROUND 
     The global high-brightness (HB) LED market grew 93% from $5.6 B in 2009 to $10.8 B in 2010, according to market research firm Strategies Unlimited after analyzing market demand as well as the supply-side activity of more than 40 HB-LED component suppliers. LCD monitor and TV backlights led the growth spurt, followed by mobile display applications. 
     The replacement of incandescent light bulbs in traffic lights around the world is arguably the first large-scale deployment of LEDs. According the Department of Transportation in California and Arizona, USA, the cost of electricity consumed in operating signalized intersection 24 hours a day averages about US$1,000 per year. The electricity bill is about 8-10× lower using the LED lights. Figuring in the periodic maintenance cost of bulb replacement during light traffic hours, the somewhat higher initial cost of LED traffic lights can be paid back in 12-18 months. This one of the main reason behind the early adoption of LED in traffic light by cities around the world. 
     In the future, to build a sustainable environment, electronic systems for our civil infrastructure, such as the traffic lights, must be advanced in several aspects. Specifically, they should be: manufactured efficiently to reduce e-waste: multi-functional systems for providing more functionality with less raw materials; deployed efficiently to eliminate redundant installation for different purposes; operated efficiently so that the same energy can be reused to perform vital functions for our ecosystem. 
     The above-described background is merely intended to provide an overview of contextual information regarding networks, and is not intended to be exhaustive. Additional context may become apparent upon review of one or more of the various non-limiting embodiments of the following detailed description.

Likewise, server  1604  can encode information and transmit the information via communication framework  1606  to one or more clients  1602 . 
     Referring now to  FIG. 17 , there is illustrated a block diagram of a computer operable to execute the disclosed LEDoS projection systems. In order to provide additional context for various aspects of the subject specification,  FIG. 17  and the following discussion are intended to provide a brief, general description of a suitable computing environment  1700  in which the various aspects of the specification can be implemented. While the specification has been described above in the general context of computer-executable instructions that can run on one or more computers, it is noted that the specification also can be implemented in combination with other program modules and/or as a combination of hardware and software. 
     Generally, program modules include routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the inventive methods can be practiced with other computer system configurations, including single-processor or multiprocessor computer systems, minicomputers, mainframe computers, as well as personal computers, hand-held computing devices, microprocessor-based or programmable consumer electronics, and the like, each of which can be operatively coupled to one or more associated devices. 
     The illustrated aspects of the specification can also be practiced in distributed computing environments, including cloud-computing environments, where certain tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote memory storage devices. 
     Computing devices can include a variety of media, which can include computer-readable storage media and/or communications media, which two terms are used herein differently from one another as follows. Computer-readable storage media can be any available storage media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable storage media can be implemented in connection with any method or technology for storage of information such as computer-readable instructions, program modules, structured data, or unstructured data. Computer-readable storage media can include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disk (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or other tangible and/or non-transitory media which can be used to store desired information. Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium. 
     Communications media typically include (and/or facilitate the transmission of) computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and includes any information delivery or transport media. The term “modulated data signal” or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communications media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. 
     With reference again to  FIG. 17 , the example environment  1700  for implementing various aspects of the specification includes a computer  1702 , the computer  1702  including a processing unit  1704 , a system memory  1706  and a system bus  1708 . The system bus  1708  couples system components including, but not limited to, the system memory  1706  to the processing unit  1704 . The processing unit  1704  can be any of various commercially available processors. Dual microprocessors and other multi-processor architectures can also be employed as the processing unit  1704 . 
     The system bus  1708  can be any of several types of bus structure that can further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures. The system memory  1706  includes read-only memory (ROM)  1710  and random access memory (RAM)  1712 . A basic input/output system is stored in a non-volatile memory  1710  such as ROM, erasable programmable read only memory, electrically erasable programmable read only memory, which basic input/output system contains the basic routines that help to transfer information between elements within the computer  1702 , such as during startup. The RAM  1712  can also include a high-speed RAM such as static RAM for caching data. 
     The computer  1702  further includes an internal hard disk drive  1714  (e.g., EIDE, SATA), which internal hard disk drive  1714  can also be configured for external use in a suitable chassis (not shown), a magnetic floppy disk drive  1716 , (e.g., to read from or write to a removable diskette  1718 ) and an optical disk drive  1720 , (e.g., reading a CD-ROM disk  1722  or, to read from or write to other high capacity optical media such as the DVD). The hard disk drive  1714 , magnetic disk drive  1716  and optical disk drive  1720  can be connected to the system bus  1708  by a hard disk drive interface  1724 , a magnetic disk drive interface  1726  and an optical drive interface  1728 , respectively. The interface  1724  for external drive implementations includes at least one or both of Universal Serial Bus (USB) and IEEE 1594 interface technologies. Other external drive connection technologies are within contemplation of the subject specification. 
     The drives and their associated computer-readable storage media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer  1702 , the drives and storage media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable storage media above refers to a HDD, a removable magnetic diskette, and a removable optical media such as a CD or DVD, it should be noted by those skilled in the art that other types of storage media which are readable by a computer, such as zip drives, magnetic cassettes, flash memory cards, cartridges, and the like, can also be used in the example operating environment, and further, that any such storage media can contain computer-executable instructions for performing the methods of the specification. 
     A number of program modules can be stored in the drives and RAM  1712 , including an operating system  1730 , one or more application programs  1732  (e.g., an image projection program), other program modules  1734  and program data  1736 . All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM  1712 . It is noted that the specification can be implemented with various commercially available operating systems or combinations of operating systems. 
     A user can enter commands and information into the computer  1702  through one or more wired/wireless input devices, e.g., a keyboard  1738  and a pointing device, such as a mouse  1740 . Other input devices (not shown) can include a microphone, an IR remote control, a joystick, a game pad, a stylus pen, touch screen, or the like. These and other input devices are often connected to the processing unit  1704  through an input device interface  1742  that is coupled to the system bus  1708 , but can be connected by other interfaces, such as a parallel port, an IEEE 1594 serial port, a game port, a USB port, an IR interface, etc. 
     A monitor  1744  or other type of display device is also connected to the system bus  1708  via an interface, such as a video adapter  1746 . In addition to the monitor  1744 , a computer typically includes other peripheral output devices (not shown), such as speakers, printers, etc. 
     An LEDoS projection system  1770  can be connected to the system bus  1708  via an interface. In an aspect, LEDoS projection system  1770  can comprise various systems presented herein. In response to receiving instructions, such as from processor  1704 , LEDoS projection system  1770  can generate an image  1772 . It is noted that LEDoS projection system can project image  1772  onto a display such as a display of monitor  1744  and/or an external display. 
     The computer  1702  can operate in a networked environment using logical connections via wired and/or wireless communications to one or more remote computers, such as a remote computer(s)  1748 . The remote computer(s)  1748  can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment appliance, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer  1702 , although, for purposes of brevity, only a memory/storage device  1750  is illustrated. The logical connections depicted include wired/wireless connectivity to a local area network  1752  and/or larger networks, e.g., a wide area network  1754 . Such local area network and wide area network networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which can connect to a global communications network, e.g., the Internet. 
     When used in a local area network networking environment, the computer  1702  is connected to the local network  1752  through a wired and/or wireless communication network interface or adapter  1756 . The adapter  1756  can facilitate wired or wireless communication to the local area network  1752 , which can also include a wireless access point disposed thereon for communicating with the wireless adapter  1756 . 
     When used in a wide area network environment, the computer  1702  can include a modem  1758 , or is connected to a communications server on the wide area network  1754 , or has other means for establishing communications over the wide area network  1154 , such as by way of the Internet. The modem  1758 , which can be internal or external and a wired or wireless device, is connected to the system bus  1708  via the serial port interface  1742 . In a networked environment, program modules depicted relative to the computer  1702 , or portions thereof, can be stored in the remote memory/storage device  1750 . It is noted that the network connections shown are example and other means of establishing a communications link between the computers can be used. 
     The computer  1702  is operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, restroom), and telephone. In an example embodiment, wireless communications can be facilitated, for example, using Wi-Fi, Bluetooth™, Zigbee, and other 802.XX wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices. 
     Wi-Fi, or Wireless Fidelity, allows connection to the Internet from a couch at home, a bed in a hotel room, or a conference room at work, without wires. Wi-Fi is a wireless technology similar to that used in a cell phone that enables such devices, e.g., computers, to send and receive data indoors and out; anywhere within the range of a base station. Wi-Fi networks use radio technologies called IEEE 802.11 (a, b, g, n, etc.) to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE 802.3 or Ethernet). Wi-Fi networks can operate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps (802.11a), 54 Mbps (802.11b), or 170 Mbps (802.11n) data rate, for example, or with products that contain both bands (dual band), so the networks can provide real-world performance similar to wired Ethernet networks used in many homes and/or offices. 
     As it employed in the subject specification, the term “processor” can refer to substantially any computing processing unit or device comprising, but not limited to comprising, single-core processors; single-processors with software multithread execution capability; multi-core processors; multi-core processors with software multithread execution capability; multi-core processors with hardware multithread technology; parallel platforms; and parallel platforms with distributed shared memory.
