DETAILED DESCRIPTION
The Figures illustrate a flashing light system 1 configured to provide a warning indication, the system 1 comprising: a plurality of lights 9 configured to flash in predetermined sequence; a transceiver 13 configured to enable wireless communication; a controller 3 configured to receive a control signal from the transceiver 13 and use the received signal to control the flashing sequence of the plurality of lights 9, wherein the control signal controls the time of day that the plurality of lights 9 are flashing.
Fig. 1 schematically illustrates an example flashing light system 1. The flashing light system 1 may be configured to provide a warning indication. The flashing light system 1 may be configured to provide a warning indication to motorists or passersby. The flashing light system 1 may be located close to potential hazards such as level crossings, pedestrian crossings or schools to warn the passersby and motorists of the potential hazards. In such examples the flashing light may only need to be turned on at particular times, for example when a train is approaching a level crossing or at the beginning and end of a school day.
The times at which the flashing lights need to be provided may be dependent on the location of the flashing light system 1. It is to be appreciated that a plurality of flashing light systems 1 may be provided and each flashing light system may need to be actuated at different times.
The example flashing light system 1 illustrated in Fig. 1 comprises a controller 3, a transceiver 13 a photovoltaic power source 5, storage means 7, a plurality of lights 9 and an ambient light detector 11. The components of the flashing light system 1 may be provided as a single unit. The single unit may be connected to, or otherwise mounted on, street furniture such as a lamp post or road sign.
The controller 3 may comprise means for controlling the system 1. The controller 3 may be configured to send inputs to and receive inputs from, the transceiver 13, the photovoltaic power source 5, the storage means 7, the light 9 and the ambient light detector 11. The controller 3 may be configured to control each of the components of the system 1.
In same examples the controller 3 may comprise one or mare processors and memory circuitry 15. The processors may be microprocessors. The memory circuitry 15 may be configured to store computer program instructions which may be accessed by the one or more processors to enable the one or more processors to control the flashing light system 1 or to control components of the flashing light system 1.
In some examples more than one controller 3 may be provided. For example, a first controller may be provided, as described above, and a second controller may also be provided. The second controller may be configured to detect the output of the photovoltaic power source 5. The second controller may be configured to detect whether it is day or night and provide an appropriate control signal to the first controller 3. In some examples the second controller could also control the level of charging of the photovoltaic power source 5.
In some examples the memory circuitry 15 may be configured to store information which is received via the transceiver 13. The stored information may then be used to control the plurality of lights 9. In some examples the memory 15 may be configured to store information which may be used to control the plurality of lights 9 for a future period of time. For instance the opening and closing times of a school for the next year or several years may be stored in the memory circuitry 15.
The transceiver 13 may comprise any means that enables the flashing light system 1 to send data to and receive data from a remote controller. The remote controller may be located a long distance away from the flashing light system 1. For example the remote controller may be located in a different building, town or city. This may enable a centralised controller to control the flashing light systems 1 over a wide geographical area.
The transceiver 13 may be configured to enable wireless communication. In some examples the transceiver 13 may be configured to enable long range wireless communication. The transceiver 13 may enable the flashing light system 1 to operate in a radio network cellular communications network or to establish a connection to the internet or any other suitable connection.
In some examples the transceiver 13 may also be configured to enable short range wireless communication. The short range wireless communication could comprise a Bluetooth connection, or a wireless local area network (WLAN) or any other suitable type of connection. This may enable the flashing light system 1 to be controlled by a user located close to the flashing light system 1. For example where the flashing light system 1 is located close to a school a user such as lollipop lady may be controlling the traffic around the school and may wish to change the pre-programmed settings of the flashing light system 1. For example there may be an accident or traffic congestion or people crossing the road which may require the flashing light system to be turned on at an additional time.
In the example illustrated in Fig. 1 the transceiver 13 has been illustrated as a single entity. It is to be appreciated that the transceiver 13 may comprise a separate transmitter and receiver. It is also to be appreciated that more than one transmitter and more than one receiver may be provided within a single flashing light system.
Some of the flashing light systems 1 may comprise a photovoltaic power source 5. The photovoltaic power source 5 may comprise any means which may be configured to convert solar energy into electrical power. In some examples the photovoltaic power source 5 may comprise one or more panels comprising photovolta ic semiconductors. The photovolta ic semiconductors may be configured to create an electric current from incident solar energy.
Some of the flashing light systems 1 may comprise a storage means 7. The storage means 7 may be configured to store electrical energy. The electrical energy which is stored by the storage means 7 may comprise energy obtained from the photovoltaic power source 5. In some examples the storage means 7 may comprise a battery which may be charged by the photovoltaic power source 5.
The storage means 7 may be connected to the photovoltaic power source 5 so that the electrical energy can be transferred from the photovoltaic power source 5 to the storage means 7. The storage means 7 and the photovoltaic power source 5 may be controlled by the controller 3 so that the controller can control when power is transferred from the photovoltaic power source 5 to the storage means 7.
The plurality of lights 9 may comprise any means which may be configured to convert electrical energy into light. In some examples the plurality of lights 9 may comprise a light emitting diode (LED). In some examples the plurality of lights 9 may comprise a plurality of LEDs. The LEDs may have low power consumption. The size and number of LEDs may be selected to meet the light levels required. In some examples the LEDs may be selected to meet official light safety standards.
The plurality of lights 9 may be arranged in pairs. The pairs of lights 9 may be arranged to flash in particular patterns. For example the lights may be arranged to flash alternately or synchronically.
The plurality of lights 9 may have a plurality of different operational modes.
The plurality of lights 9 may have an off mode in which it is turned off so that no light is generated. When the plurality of lights 9 are in the off mode the power generated by the photovoltaic power source 5 is not needed by the plurality of lights 9 and so it may be provided to the storage means 7. The controller 3 may control the flashing light system 1 so that when the plurality of lights 9 are in the off mode the power is provided to the storage means 7.
The operational modes of the plurality of lights 9 may also comprise a plurality of on modes. Each of the on modes may have a different brightness level.
This may enable the same plurality of lights 9 to provide different brightness of light as is required. The controller 3 may control the brightness of light which is provided by controlling which of the operational modes of the plurality of lights 9 is selected.
The different on modes of the plurality of lights 9 may require different amounts of power to generate the required brightness level. For example the brightest on mode may require more power than a duller on mode or the off mode. In such examples if the photovoltaic power source 5 is not generating enough power then the plurality of lights 9 may obtain additional power from the storage means 7. This may be the case if it is night time, or during cloudy or foggy weather conditions which have low levels of solar power but require a bright light to be provided.
If the photovoltaic power source 5 is generating more power than is required then the excess power may be provided to the storage means 7. This may be the case if it is day time, or during sunny weather conditions which have high levels of solar power and so do not require a very bright light or do not require any additional light at all.
The plurality of lights 9 may be configured to flash on and off to provide a warning indication. The warning light may be configured to flash on and off at predefined times.
In some examples the flashing light system 1 may comprise an ambient light detector 11. The ambient light detector 11 may comprise any means which may be configured to detect the ambient light levels around the flashing light system 1 and provide the controller 3 with an input signal indicative of the detected ambient light levels. The ambient light detector 11 may comprise one or more photosensors or other suitable means which may be configured to convert incident light to an electrical signal.
The ambient light detector 11 may be synchronised with the flashing of the plurality of lights 9 so that the ambient light is detected when the plurality of lights 9 have flashed off. This may avoid the light generated by the plurality of lights 9 from affecting the measurements obtained by the light detector 11.
Fig. 2 schematically illustrates an example method which may be implemented using the control system of Fig. 1 and as described above.
The method comprises, at block 21, enabling wireless communication 21.
The step of enabling wireless communication may comprise using the transceiver 13 to establish a wireless communication connection between the flashing light system 1 and a remote controller. The wireless communication connection may comprise an internet connection or a cellular communication connection or any other suitable communication connection. The wireless communication connection may be a long range communication connection.
The method also comprises, at block 23, receiving a control signal. The control signal may be received from the remote controller via the transceiver 13. The control signal may comprise information which may be used to control the flashing of the plurality of lights. For example the control signal may comprise information which controls the time of day at which the plurality of lights 9 are to be activated. Such information may include details such as the opening and closing time of a school or information relating to a train
timetable.
Some of the information received in the control signal may be stored in the memory circuitry 15. The information stored in the memory circuitry 15 comprises information used for controlling the flashing light system for a future period of time.
At block 25 the method comprises using the received information to control the plurality of lights 9. For example the received information may be used to control the time of day at which the plurality of lights 9 are configured to flash.
The embodiments of the invention may provide a flashing light system 1 which may be controlled remotely. This may enable a centralized controller to control a plurality of flashing lights systems 1. This may also enable changes to the pre-programmed times for flashing to be made without someone having to visit the flashing light system 1. This may provide for a more efficient flashing light system 1 for providing a warning light indication.
In some examples the efficiency of the flashing light system may be increased by using the ambient light detector 11 to monitor the ambient light around the flashing light system 1. The ambient light detector 11 may monitor the ambient light for an extended time interval. For example the ambient light detector 11 may monitor the ambient light for a period of ten minutes. This may avoid the flashing light system 1 responding to a temporary change in the light level such as a passing cloud or other object temporarily obstructing the incident sunlight. The controller 3 may then control the brightness of the plurality of lights 9 in order to use power most efficiently. The controller 3 may control the brightness of the plurality of lights 9 by controlling which of the plurality of on states is selected. For example if it is determined that the ambient light is very bright then the plurality of lights 9 may be turned to a higher brightness setting. If is determined that the ambient light level is very low then the plurality of lights 9 may be configured in a lower brightness setting.
The controller 3 may also control the power which is provided to the plurality of lights 9 by the photovoltaic power source 5 and the storage means 7. The controller 3 may be configured to determine how much power is being generated by the photovoltaic power source 5. If this energy is sufficient then all the power supplied to the plurality of lights 9 may be provided directly from the photovoltaic power source 5. If this energy is not sufficient then additional power may be provided to the plurality of lights 9 from the storage means 7.
In some instances the photovoltaic power source 5 may be generating more power than is needed by the plurality of lights 9. In such instances the controller 3 may control the photovoltaic power source 5 to provide the surplus power to the storage means 7. This may be used to save the power so that it can be used at a time when the photovoltaic power source 5 is not generating sufficient power for the plurality of lights 9.
The flashing light system 1 may be configured to operate without any additional power source. This may mean that there is no requirement to connect the flashing light system I to a mains power supply. This may make the flashing light system 1 easier to install as it removes the need to dig up the ground to connect a street light to a power supply. This may also enable a street light to be operable with zero carbon emissions.
The blocks illustrated in the Fig. 2 may represent steps in a method and/or sections of code in a computer program. The illustration of a particular order to the blocks does not necessarily imply that there is a required or preferred order for the blocks and the order and arrangement of the block may be varied.
