Definitions

  • the present invention relates generally to solar powered lighting systems and in particular the invention provides a lighting system with intelligent power management.
  • Embodiments of the present invention are directed toward autonomous solar-powered footpath/park/street lamps, centrally-powered multiple lamp systems, warning/advertising signs and billboards, security lighting and emergency lighting supply.
  • solar powered lighting systems are known wherein standard solar cells, battery accumulators and lighting devices are combined in a conventional manner.
  • these prior art systems generally suffer from poor efficiency and/or poor component lifetimes resulting in relatively high overall installation and maintenance cost. Summary of the Invention
  • the present invention consists in a lighting system comprising photovoltaic energy conversion means arranged to convert light energy into electrical energy, energy storage means arranged to store said electrical energy and to deliver said energy as required, lighting means connected to the energy storage means via power regulating means arranged to control the delivery of power to the lighting means, control means arranged to determine a lighting demand and to control the regulating means to provide power to the lighting means in response to the lighting demand, and proximity detection means arranged to detect the presence of an object or person in or near the illuminated field of the lighting means, the control means being responsive to the proximity detection means when determining the lighting demand.
  • the proximity detecting means includes a motion detection device and/or an acoustic detection device, such as a microphone, whereby any motion or any sound above a predetermined threshold detected in the vicinity of the lighting means, will create a light demand resulting in an increase in the intensity of the light output of the lamp.
  • control means includes a stored energy monitoring means arranged to monitor flow of energy into and out of the energy storage means and to maintain an indication of currently available stored energy.
  • the control means will preferably adjust the energy delivered to the lighting means in response to lighting demands, available stored energy and time of day in order to maintain reserve lighting capability which is a function of an expected time of remaining darkness.
  • control means maintains lighting demand history statistics and adjusts the anticipated lighting requirement in accordance with those statistics.
  • control means will also maintain charging history statistics, determine an expected charging rate for upcoming charging periods and adjust energy usage to increase the probability of long term availability of lighting capability.
  • the present invention consists in a method of controlling a photovoltaic powered lighting system including photovoltaic energy conversion means, battery accumulator means, lighting means, power regulating means for regulating power to the lighting means from the battery accumulator means, proximity detection means and control means, the method comprising the steps of maintaining the lighting means at a predetermined standby state by controlling the power regulating means to supply a standby power level, periodically or continuously monitoring the proximity means to determine if an object or person has moved toward or remains in or near the field of illumination of the lighting means to determine a lighting demand, continuously monitoring the power energy available in the accumulator, determining the demand probability to the next charging period when a lighting demand exists, calculating a maintainable usage rate that will allow the probable demand to be met with the currently available stored energy and regulating power to the lighting means in accordance with the maintainable usage rate while a demand exists.
  • control means will periodically or continuously update the demand probability to the next charging period taking into account current demand and will adjust the maintainable usage rate accordingly.
  • Figure 1 shows a block diagram of an embodiment of the invention
  • Figure 2A- is a set of flow charts illustrating the programme flow in the controlling programme of the embodiment of Figure 1.
  • the primary function of a solar-powered lighting system becomes one of resource management, that resource being energy.
  • incident radiant energy from the sun is converted to electrical energy by the photovoltaic cells 11.
  • This electrical energy is converted to chemical energy by the storage battery 12, where it is stored until required for illumination.
  • the storage battery 12 converts the stored chemical energy back to electrical energy.
  • the lamp 13 converts this electrical energy back to radiant energy to provide illumination. All of these processes of energy conversion and storage must be achieved as efficiently as possible to provide an effective solar-powered lighting system.
  • Each of the major energy conversion devices - photovoltaic cells, storage battery and lamp/reflector - are all critical components in achieving the efficiencies desirable for a viable solar lighting system.
  • the responsibility of managing the energy collection, conversion and storage processes is the function of the Intelligent Solar Lighting System 10 illustrated in Figure 1.
  • the system 10 must accomplish these tasks while achieving maximum efficiencies, minimum energy losses and ensuring maximum system component life.
  • the system 10 comprises two discrete elements: the system “hardware” and the embedded system “software” represented by the flow charts of Figure 2A-M. It is the controller "software” resident in the Digital Logic Engine 25 that provides the intelligence to drive the solar lighting system energy management.
  • the tasks of the controller 25 may be clearly divided into two functional areas: 1. the management of collecting, storing and computing energy during daylight; 2. the management of utilising the stored energy for illumination at night.
  • the controller 25 must ensure that the available energy collected and stored is maximised whilst the life of the storage batteries is also maximised.
  • the controller 25 monitors sensors for battery voltage 15, PV cell voltage 14, charging current 17, battery temperature 16 and PV cell temperature 18. "Dithering" techniques (refer Fig. 2H, item 187) are employed to achieve maximum power point tracking for the PV cells.
  • the storage battery 12 is computer modelled (refer Fig. 2G, items 171-180) and data from the sensors is processed to ensure optimum charging rates and maximum battery life via battery charger/regulator 26.
  • the controller 25 maintains records of energy statistics and varies the computer modelling to predict changes in performance with battery ageing. The collected energy is accurately measured and the available stored energy is computed from the dynamic computer battery modelling.
  • the controller 25 In managing the utilisation of stored energy, the controller 25 provides a level of illumination commensurate with demand. Sensors detecting noise 19 and movement 21 enable the controller 25 to determine the utilisation of the area being serviced by the lamp.
  • the controller 25 processes data reflecting area utilisation, ambient light levels, time-of-day, time-of-year, geographic variables, available stored energy and statistical energy usage patterns to determine not only when to provide illumination, but how much illumination to provide.
  • Embodiments of the invention are arranged to efficiently drive any of the following lamp types with variable luminance: Induction, fluorescent, low/high pressure vapour, resonant- transformer metal halide. This range of lamps will provide solutions to lighting applications which have the following disparate demands: maximum service life, best colour rendering index, lowest capital cost, highest efficiency.
  • the induction lamp represents a revolutionary new lamp technology.
  • the lamp employs the combination of electromagnetic induction and gas discharge.
  • a ferritecore inductor is excited at a frequency of 2.6 MhZ.
  • the resulting electromagnetic field causes eddy currents to flow in the low- pressure gas, producing ionisation.
  • the resulting recombination radiation in the ultraviolet spectrum causes a coating on the inside wall of the glass envelope to fluoresce.
  • the induction lamp has the following attributes: exceptionally long life, very high efficiency, flicker-free operation, excellent colour rendering index, instantaneous start-up, constant light "quality" with varying illumination.
  • the extraordinary induction lamp lifetime offers the unique possibility of a hermetically sealed lamp/reflector compartment. This will permit the utilisation of very high performance reflector materials that would normally be damaged by dust or condensation. In turn, this will permit a very highly efficient lamp/optical system to be used.
  • PV array 11 In an autonomously solar-powered lamp, it is desirable to keep the size of the photovoltaic (PV) array 11 as small as possible in order to reduce the engineering complexities associated with wind loading. It is also desirable to keep the PV array size at a minimum to enable industrial designers to produce an aesthetically acceptable result.
  • a "wireless" communications link 22 is provided between individual lamps in a system.
  • This radio communications network enables:
  • embodiments of the invention will include a power transmission system 23 to transmit electrical energy between units with minimum losses. This is achieved through HF power transmission over low- loss RF transmission lines. This feature also enables a solution to the problem of differential shading in autonomous-supply lighting, by sharing collected energy between neighbouring units.
  • a power controller 27 is also provided to channel energy directly from the storage batteries, from the HF power network, or energy from an existing power grid 24. This approach enables solar energy to supplement existing energy supply, or to provide emergency lighting in the absence of grid supply.
  • the controller 25 provides the "intelligence" to select the energy source and control the amount of energy delivered to the lamp(s).
  • a system of speech annunciation may also be incorporated into some embodiments of the invention.
  • This system enables pre-recorded digitally stored speech messages to be delivered upon sensing the presence of a person. Warning messages associated with environmental factors, such as UV radiation levels, could be initiated automatically local sensors.
  • the "wireless" communications link will support digital speech message packets, enabling real-time speech messages to be originated at a central node and distributed to the network.
  • Figures 2A-2E illustrate, Reset, Initialization and Executive functions of the controller and the operation of these functions will be readily understood by a skilled addressee.
  • Figures 2L and 2M illustrate simple interrupt routines which will also be readily understood.
  • this illustrates the operation of a section of the control program known as the day/night supervisor.
  • a test 161 is performed to test a day/night flag and if the flag is set to indicate that it is presently daytime, control passes to a first path 162.
  • a test 163 is performed to determine if the time of day agrees with the day/night flag and if not, the state of the flag is changed 164 to "Early Night" recognising that the time must have just passed the transition from day to early night.
  • the night/day decision is based on stored information of year round clear sky light levels for the lamp location.
  • an ambient light test 165 is performed and if this indicates a low ambient light level (eg. due to cloud cover) then the day/night flag will again be set 164 to Early Night.
  • control is passed to the day supervisor Routine (refer Fig. 2G). Otherwise, when the day/night flag is set to early night, control signals are initiated 166 to slowly ramp the lamp output from off to the current maximum threshold. The ambient light threshold of the light detection subsystem is then increased 167 to allow for the output of the lamp and minor fluctuations in ambient illumination.
  • test 161 indicates that the day/night flag is set to early night
  • a time of day test 168 is performed and if this test confirms that the time is early night, control reverts to the Supervisor Background Routine (refer Fig. 2J). Otherwise, the day/night flag is set to "Late Night” 169 and control signals are initiated 170 to ramp down the light output of the lamp to the current minimum threshold. Control is then handed over to the late night supervisor (refer Fig. 21) awaiting an indication of activity in the area covered by the lamp (see later description of late night supervisor).
  • test 161 indicates that the day/night flag is set to late night
  • a time of day test 261 and ambient light test 262 are performed and if these indicate that the day/night flag is correct, control is passed to the Late Night Supervisor Routine of the program (refer Fig. 21), otherwise the day/night flag is set to day 263 control signals are initiated 264 to turn off the lamp, the ambient light threshold is decreased 265 and control is passed to the Supervisor Background Routine (refer Fig. 2J).
  • the Day Supervisor routine first performs a number of steps to check the status of the battery including reading the measurement of ambient and battery temperature 171; reading the measurement of battery voltage 172; reading a measurement of change in energy stored 173 and testing the computer model of the battery 174 and 175 to determine if the model is still valid. In the event that the model is not valid the model parameters are revised 176.
  • the battery model is then used to compute the total stored energy 177 and to determine if the battery is fully charged 178. In the event that the battery is fully charged, the state of the charger is tested 179 and if on, control signals are initiated 180 to turn the charger off and control is returned to the Supervisor Background Routine (refer to Fig. 2J).
  • the program goes on to check the charging conditions (refer Fig. 2H). Firstly, the charge rate is checked 181 and if below maximum the current charge current is measured 182 and the optimum charge current computed 183 and compared 184 with the actual current. If the charging current is not optimum the charging rate is adjusted 185 and the charging status updated 186.
  • the charging rate is at maximum the PV cell voltage and temperature are measured 287
  • the charge current is measured 188
  • the maximum power point of the PV cell is computed 189
  • Dither processing is performed 190.
  • the operating parameters are then compared with the computed maximum power point 181 to determine if charging is optimal and if not the Dither flags are updated 187 and the charging rate adjusted 282.
  • the energy storage statistics are then updated and control is passed to the Supervisor Background Routine (refer 15 Fig. 2J).
  • the lamp status is first tested to determine if the lamp output is high or ramping up and in each case control passes immediately back to the Supervisor Background Routine. If the lamp status indicates that the lamp output is low or ramping down the motion status, noise status and telemetry status are tested 192, 193. 194 to determine if there is any reason to increase light output, such as detection of motion or as the result of a telemetry signal requesting a change. If no change is required control reverts to the Supervisor Background Routine (refer Fig. 2J), otherwise control signals are initiated 195 to ramp the lamp output up and the sensor block flag is set 196 before returning control to the Supervisor Background Routine.
  • FIGS 2J and 2K show the flow of the controller program in the Supervisor Background Routine. This section of the program performs housekeeping tasks and switches control to other sections of the control program.
  • the first task that the Supervisor Background Routine performs is to transfer all real-time calls to poll service 301, after which a day/night test is performed 302 to switch control to the relevant part of the supervisor program. If it is currently night time (i.e. lights on and no charging) the energy usage is measured 303 the remaining stored energy computed 304 and energy usage projections computed 305.
  • a test 306 determines whether it is currently late night or early night and energy reserves are compared with expected demand 307, 308. In the event that energy levels are good the energy use statistics are updated 314 (refer Fig. 2K), whereas if energy reserves are low the maximum light levels are adjusted 309.310 and in the case of late night operation the time ⁇ out values are adjusted 401 before control passes to the second part of the Supervisor Background Routine shown in Fig. 2K.
  • Supervisor Background Routine performs periodic housekeeping tasks 315, performs diagnostics tests, 316, 317, tests the diagnostic status 318, sets error flags 319,320 in accordance with the outcome of the diagnostic test and returns control to the Executive Task
  • the Executive Task Supervisor Routine responds to any error flags, if set, or if no errors exist passes control back to the Day/Night Supervisor Routine (refer Fig. 2F), the Day Supervisor Routine (refer Fig. 2G) or the Supervisor Background Routine (refer Figs. 2J & 2K).
  • control systems could be retro-fitted to existing street lighting installations or supplied as component parts of new street lighting proposals.
  • Figure 1, communications (22), may be either by radio link or signalling over the existing power network.

Abstract

Un système d'éclairage intelligent (10) maximise l'énergie disponible collectée et stockée ainsi que la durée de vie des batteries de stockage en surveillant la tension des batteries (15) et des cellules photovoltaïques (14), le courant de charge (17), la température des batteries (16) et celle des cellules photovoltaïques (18). Les batteries de stockage (12) sont conçues par ordinateur et des données provenant de capteurs sont traitées de façon à assurer des régimes de charge optimaux et une durée de batterie maximale grâce à un régulateur (26) de chargeur de batterie. Ce système (10) gère en outre l'utilisation de l'énergie de façon à fournir un niveau d'éclairage correspondant à la demande. Des détecteurs de son (19) et de mouvement (21) permettent à ce système (10) de déterminer l'utilisation d'une zone devant être éclairée par une lampe (13). Le circuit de commande traite des données d'utilisation de zone et de niveau d'éclairage ambiant, des variables chronologiques, saisonnières et géographiques, et des modalités d'utilisation statique de l'énergie stockée pour déterminer à quel moment fournir quel éclairement.
