Definitions
- This invention relates to a method and apparatus for the supply of power to electrical appliances such as electric lights and seeks to reduce the cost of operating such devices.
- electrical appliances are supplied with power via cables connected to a central source of electrical power such as the mains power supply or a generator. Where room heating is required.
- Electrical heaters can be used but it is generally considered to be more economical to employ a central heating system by which a fluid is heated in a single heating unit (often referred to as a "boiler") before flowing into spaces to be heated.
- the fluid can be a liquid such as water or oil which is made to circulate through a system of radiators; or it can be air which passes along ducts and out of vents to mix with and warm the ambient air in the spaces to be heated.
- This invention arose from the realisation that, because electrical appliances are normally installed in spaces which are served by a central heating system, the infrastructure of the central heating system, can be used to distribute relatively low cost energy to the electrical appliances, subject to a suitable interface being included, locally with respect to each appliance to convert the heat energy to electricity.
- a method of supplying electrical power to at least one electrical consumption point characterised in that a central heating system is used to transfer heat energy to a thermoelectric device connected to supply electricity to the said consumption point.
- the consumption point could take any of a variety of different forms.
- it could be a socket or other connector designed to be connected to an electrical appliance; or it could be a mobile phone charging device; or it could be the electrical appliance itself such as a lamp fitting.
- the invention is considered to have particular benefit for supplying power to light fittings because lighting is almost always required in spaces that are required to be heated.
- the device could be used as a main source of light or for emergency lighting.
- thermoelectric device attached to a radiator or otherwise arranged so that its hot side is heated by the circulating liquid or by the hot air from a vent of a hot air heating duct.
- the thermoelectric device is used to produce a local source of electricity which is then used e.g. to drive a light source such as a light emitting diode (LED) light source.
- the thermoelectric device and the consumption point may have a common housing so that they form a single unit. Alternatively they may have separate housings joined by an electrical conductor.
- thermoelectric device Where a circulating-liquid central heating system is used, it would be possible for the hot side of the thermoelectric device to be located within a central heating radiator so as to be in direct contact with the circulating fluid. However, it is preferred to employ a design that allows the hot side of the thermoelectric device to be held in close thermal contact with an exterior surface of the radiator. This allows the device to be easily retrofitted to an existing central heating system without penetrating.
- the cold part of the thermoelectric generator is preferably provided with a heat dissipation means, eg an arrangement of heat-conductive vanes or other projections to facilitate transfer of heat to the ambient air. Where the device is not required to be retrofitted, it would be possible to build it into the radiator between a wall of the radiator and a generally conventional arrangement of heat dissipation fins or equivalent.
- the invention is of particular value for use in a system where a number of electrical consumption points are needed since the provision of radiators at different locations provides a ready made mechanism for distributing energy to plural positions.
- Fig 1 is a schematic block diagram showing a light source constructed in accordance with the invention.
- Fig 2 shows how two or more light sources, like that of Fig 1, may be positioned on respective radiators of a water-circulation central heating system;
- Fig 3 shows, at 3A and 3B, vertical and horizontal cross-sections through the light source of Fig 1 and through a part of a radiator to which it is attached.
- a consumption unit in the form of a light fitting 1.
- the light fitting includes a thermoelectric generator IA which is an off- the-shelf component.
- the electrical output from the generator IA is passed to a power management circuit IB which provides a stabilized voltage to charge a re-chargeable battery 1C and to power a light emitting diode (LED) driver board ID which carried LEDs IE of sufficient power for illuminating a room or corridor.
- Power to the LED board ID is controlled by a movement sensor switch IF which is of conventional construction and which closes when a person is detected in the vicinity of the switch and for a fixed time thereafter.
- a movement sensor switch IF In series with the switch IF is another switch IG which is designed to open when ambient light conditions are sufficiently good to make it unnecessary to provide extra lighting.
- Fig 2 shows a fluid-circulation central heating system in which two light fittings 1, like that of Fig 1, are attached to respective radiators 2 connected to receive hot water from a boiler 3 via flow pipe 4 A and to return cooler water via pipe 4B to the boiler 3.
- Figs 3A and 3B show the physical configuration of one of the light fittings in more detail. It comprises a generally hemispherical housing IH of moulded synthetic plastics material having vents II at top and bottom and a front opening IJ.
- the housing has recesses on its edge to receive receiving permanent magnets IK (Fig 3B) by which it is attached to a conventional steel radiator 2.
- Its inner surface is formed with a recess that houses the re-chargeable battery 1C and lips or recesses that serve to locate the thermoelectric generator IA, a circuit board 5 and the LED board ID.
- Figs 3A and B show that the hot side of the thermoelectric generator is held in close thermal contact with a flat surface of the radiator. Its opposite, cold, side is defined by a finned heat dissipation block IA'.
- the circuit board 5 carries the power management circuit IB, the movement sensor IF and the light sensitive switch IG.
- a number of units like that shown in Fig 3 would be attached to radiators spaced along a corridor. Provided the sensor IG indicated that there was a low level of ambient light, each unit would provide illumination whenever a person entered its vicinity as detected by the sensor IF.
- the lighting system provided by the illustrated device uses energy distributed in the form of heat from a central heating system, it can be operated more economically than conventional lighting supplied via a conventional wired distribution system.
- the housing can be of a different shape, eg elongated, to fit onto flat parts of radiators that are ribbed or otherwise not flat.
- the housing could be attached to the radiator by means other than magnets eg by clamps or by adhesive, and the "hot" side of the thermoelectric generator could carry a deformable layer of heat conductive material or a heat-conductive adhesive layer to accommodate any imperfections in the shape of the radiator surface and thereby to provide a good thermal contact.
- the device could be shaped to fit over a standard cylindrical water pipe forming part of the heating system. Instead of lamps, the device could be designed to provide power to operate an intruder alarm, thermostatic controls for the central heating system, a battery charger eg for mobile and cordless phones and for many other purposes.
- Battery means any cell or group of cells for converting chemical energy to electrical energy and, in the case of a re-chargable battery, for reversing the process by converting electrical energy to chemical energy.
- Consumption Point means any device which consumes electrical energy or which acts as a connector or transformer for passing electricity to a device that consumes electricity.
- Fluid-flow heating system means a heating system comprising a heat source arranged to heat a fluid, and means for distributing the heated fluid into or through spaces to be heated.
- Radiator is a device connected in a fluid-flow central heating system, through which the heated fluid flows and which is designed to transfer the heat from the fluid to surrounding air by conduction, convection or radiation.
- Thermoelectric device means any device which has a "hot” part and a “cold” part and which generates an electric potential difference when the hot part is maintained at a higher temperature than the cold part.
