Description:ILLUMINATING SYSTEM FOR FLEXIBLE LIGHT DISTRIBUTION

FIELD OF THE INVENTION:

[0001] The present invention relates to an improvement, or a modification of the invention claimed in the specification applied under the application number 201911014012 (parent application). The parent application relates to street light automation system provisioned to communicate wirelessly for illumination of street lights. The present invention is in continuation with the parent application and relates to a street light automation system that provides flexible light distribution along a road by means of a fiber optic cable.

BACKGROUND OF THE INVENTION:

[0002] In general, street lights are installed at roadsides in order to provide safety for vehicle traffic or human walking at night. Conventionally, the lamps are turned on or off by wireless services that operates switches installed as and when required. For an instance, the method of turning on and off the street lamp at a predetermined time is performed by an automatic program, i.e., human assistance for lighting and turning off is not necessary. However, since the time of turning on and off the street lamp varies depending on the annual seasons, there is a problem of changing the program every time. In addition, there is a disadvantage in that the cost of producing the program is excessive.

[0003] Further, with the explosive growth of wireless services, the problems of network performance, upgrading construction cost, energy consumption and the like of the traditional wireless access network become more and more serious. The traditional distributed base station makes the cost of the communication operator on the laying and operation and maintenance of the network become larger and larger as the limited frequency spectrum resources are not effectively reused. The traditional street lamp control method is single and rigid that cannot meet the requirements of real-time monitoring and intelligent management requirements of modern lighting.

[0004] Additionally, most of the existing urban street lamp systems are uniformly turned on and off, the influence of many factors such as district, time, climate, stream density and the like are not considered, and particularly, the street lamps are still turned on at night when the traffic flow and stream are less, so that a considerable part of power resources are wasted.

[0005] There is, therefore, a dire need to develop a system for transmission of signals by most economical resources.

SUMMARY OF THE INVENTION:

[0006] The following presents a simplified summary of the invention to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the present invention. It is not intended to identify the key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some concept of the invention in a simplified form as a prelude to a more detailed description of the invention presented later.

[0007] The improvements and/or modifications from the main invention:
The parent application discloses a street light automation system provisioned to communicate wirelessly for automatic on-off or step dimming control provisions of the LED based street lights, thereby reducing the emission of carbon content to a huge extent by dimming the lights when it is not required. The present invention improves upon the main invention by providing an illuminating system compatible with optical signal transmission and electric energy transmission for providing flexible light distribution along a road.

[0008] It is, therefore, an object of the present invention to achieve optimal signal transmission for controlling brightness of street lamps according to object existence within a pre-determined area.

[0009] Another object of the present invention is to prevent the waste of energy caused by always lighting ON the street light without any requirement.

DETAILED DESCRIPTION OF THE INVENTION:

[0014] Embodiments, of the present disclosure, will now be described with reference to the accompanying drawing.

[0015] The following detailed description illustrates the invention by way of example, and not by way of limitation. This description will clearly enable one skilled in the art to make and use the invention and describes several embodiments, adaptions, variations, alternatives, and uses of the invention, including what we presently believe is the best mode of carrying out the invention.

[0016] The present invention relates to a communication system having synchronization with plurality of equipments or other systems for providing seamless connectivity to users through a transmission channel. More particularly, the communication system may provide various light signals or combination of light signals for use in association with communication of information. These light signals may also be encoded. According to the present invention, such light signals may be transmitted by a cable made by tying several strands of optical fiber to a particular equipment while ensuring protection against long-term sunlight and ultraviolet rays to satisfy safety of the equipment.

[0017] Reference is now made to FIG. 1 an exemplary communication system (100) for providing seamless connectivity to multiple smart devices or other systems within a given area. In another words, FIG. 1 shows a simplified block diagram of how Internet access can be provided with an optical fiber cable. The communication system (100) may be provided with a number of services to select when accessing cloud services over an Internet (102). In one example, the communication system (100) may communicate with sewage plant (104) for treatment of sewage water. In another example, the communication system (100) may communicate with pump automation system (106) for controlling activities within a pump station.

[0018] In yet another example, the communication system (100) may communicate with an illumination system (108) for flexible light distribution provided along a road. It may be noted that the sewage plant (104), the pump automation system (106), and the illumination system (108) may alternatively be referred as system (106,108,110). The system (106,108,110) may correspond to ethernet based systems that follows one or more known IP (Internet Protocol).

[0019] In an embodiment, a server (110) may be kept within a given premises and acts as a source of dedicated communication network called as Network Operation Centre (NOC). The server (110) is enabled to receive a set of information from the systems (104, 106, 108) by wired or wireless communication means. Further, the server (110) may be configured to operate on a switch (112) to control various functions of the systems (104, 106, 108). In one example, the switch (112) may connect systems (104, 106, 108) in a network to each other, enabling them to operate by exchanging data packets. Further, the switch (112) can be a hardware device that manage physical networks or software-based systems. It may be noted that the switch (112) may operate on the data-link layer, or Layer 2, of the Open Systems Interconnection (OSI) model.

[0020] Further, the systems (104, 106, 108) may transmit signals to the server (110) through an optical line terminal (114). The optical line terminal (114) may act as endpoint hardware device in a PON (Passive optical network). It connects with the switch (112) for uplink and transfers optical signal through the PON. Thereafter, the optical signal may be disturbed by a panel (116) through its uplink uniformly across all output ports to a plurality of Optical Network Terminals ONTs (118). In an example, the ONT (118) is a device that connects fiber optic cables to other wiring such as ethernet based systems (106,108,110) and other multiple devices such as a smart grid (120), a telephone (122), a laptop (124), and the like. Further, the system (104, 106, 108) may comprise plurality of splitter for distributing optical signal uniformly across all output ports to different ONTs.

[0021] Reference is now made to FIG. 2 that illustrates the illuminating system (108) connected with Internet (102) and ONTs (118) through optical fiber cables for flexible light distribution along a roadside. Further, an internet provider (202), connected to the Internet (102), may provide Internet Access (204) to a relay (206) through control cable (207). In order to inject the signals via a street light control apparatus (208) that can modulate, alter, or otherwise adapt the Internet signals (not shown) for transmission over the ONTs (118) to poles (2101, 2102,) through power cable (209). In one case, the ONTs (118) may comprise of optical line terminal that enables illumination along the roadside. Alternatively, the optical line terminal may correspond to a plurality of fiber optic cable (212) of pre-determined length.

[0022] In an embodiment, the illumination system (108) may relate to a plurality of street lamps (2141, 2142) having an illumination function using the optical cable (212), i.e., the street lamp (2141, 2142) is used according to the installation place, such as the highway, the main road in the city, commercial district road, residential district road. Further, the light communication system may be formed of a single row, single source, or an array of Light Emitting Diode (LED) units (not shown) configured on a light support and in electrical communication with a controller and a power supply, battery, or other electrical source. In one case, the optical line terminal or the fiber optic cable (212) is provided at a periphery of an upper head of a pole member.

[0023] The plurality of LED units may be mounted on a pole member (2161, 2162), wherein each of the LED units is divided in at least two groups. The first group is provisioned to enable a dim state for the plurality of LED units and a second group is provisioned for automatic switching ON/OFF of the plurality of LED units. The functioning of the LED units is based upon object existence within a pre-determined area. More particularly, an object detecting unit may generate an object detection information based upon the object existence. Upon determination of the object existence, a mini panel pertaining to each LED unit may allow the optical line terminal (212) to illuminate each group at a time depending upon the object detection information. In one example, the mini control panel may be monitored by a control unit comprising a main controller panel. Further, each LED unit is capable of communicating with the control unit using the optical line terminal.

[0024] The foregoing descriptions of exemplary embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiment was chosen and described in order to best explain the principles of the invention and its practical application, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.
