Abstract

The invention consists of a removable device that can be fitted easily to radiators or other domestic heating outlets and uses the heat energy available to generate low-level electrical power. The device can be clamped magnetically to a hydronic radiator and provides lighting without any extra power input than would normally be provided to the radiator.

Description

Means for Providing Thermally Generated Light
Description
One embodiment of this invention consists of a lighting appliance according to figure A thermoelectric generator a. is connected thermally to a heatsink b on one side and to a domestic radiator c. on the other side.
The thermoelectric generator is connected electrically to a power conditioning board d The board supplies power to a multiplicity of light emitting diodes (LEDs) e.
When the radiator is in use, there is generated a temperature gradient between the radiator and the heatsink which is cooled by ambient air, turn The thermal gradient causes heat flow through the generator, which in tein-generates an electric potential between the two output wires f.
The power conditioning board converts the current and voltage from the generator to appropriate current and voltage for the LEDs.
In this way light is provided to the room that the radiator is in. Additionally no mains or battety electrical power is required to provide this light.
There is no loss of heating capacity of the radiator as thermal energy taken into the invention is converted into electrical energy and thence into light energy which, when it falls upon any surface within the room, will be converted back into heat energy.
Any loss of energy in the system and also the heat given off by the heatsink manifests as thermal energy and therefore no net heating is lost.
This invention is intended for use on hydronic heating systems. Advantageously in winter when the heating system is most in use the available natural light is at a minimum and thus this invention can be of most use. Advantageously the light provided by this invention requires no extra expenditure of electrical or thermal energy than would otherwise be used. Therefore it provides light without any extra use of fossil fuels. Expenditure by the user on electricity for lighting purposes can be reduced by use of this device. One embodiment includes electrical storage and thus the stored up clectricity can be released to give a greater intensity of lighting when needed. Alternatively the device can be used for security purposes by being provided with a sensor that will detect the presence of intniders. Additionally the device can be used as emergency lighting when mains power is unavailable.
Unlike the invention, prior art use of thermoelectric generators involved attachment of generators to combustion devices to provide power for lighting and other purposes.

Claims (6)

  1. Claims I. A removable device whereby heat from a heating system is utilised to generate electrical power by use of thermoelectric generators for the purpose of lighting.
