Definitions

  • the present invention mainly relates to heat source and more particularly use of Light Emitting Diode (LED) as heat source.
  • LED Light Emitting Diode
  • thermostat in series with the coil. Heating is commonly done to temp of 180- 200 degree Celsius.
  • Heating elements are Nichrome, resistor wire like kanthal (FeCrAI) wire, Nichrome wire and strip, cupronickel (CuNi) etc.
  • the LED is often small in area (less than 1 mm 2 ), and integrated optical components may be used to shape its radiation pattern.
  • Early LEDs were often used as indicator lamps for electronic devices, replacing small incandescent bulbs. Recent developments in LEDs permit them to be used in environmental and task lighting. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching.
  • Another objective of the present invention is to reduce the power consumption for heating purposes like iron box, bread toaster, water heater etc by using LED as a heat source which is nearly 1/10 times less as compared with current coil based technology.
  • the figure shows an example of developing a led iron Box.
  • the led iron box consists of power supply, current driver, illumination device (led array), and heat conducting plate or base plate (heat conducting plate acts as heat sink).
  • the high power LED array linked to a heat conducting plate using thermal conductive dielectric.
  • the suitable supply to LED array forms an LED iron box.
  • the thermal conductive dielectric ensures thermal conduction without electric conduction to the plate.
  • LED array it should be provided with a particular range of current.
  • present invention uses a suitable current driver.
  • Input supply to DC of suitable current or DC from battery can be directly used, which is then supplied to LED array. When LED turns ON the heat is produced.
  • the LED array is mould on to base plate using thermal dielectric and the led array transfers the heat to the base plate.
  • the present invention "LED as a heat source” reduces power consumption for heating purposes.

Abstract

La présente invention se rapporte à un système permettant d'obtenir de la chaleur à partir d'au moins un dispositif d'éclairage à des fins de chauffage. Selon un mode de réalisation, le système comprend : une alimentation électrique destinée à alimenter le circuit de commande de courant, l'alimentation électrique comprenant une alimentation alternative ou continue ou les deux, un circuit de commande de courant couplé à au moins un dispositif d'éclairage pour fournir le courant en continu, le circuit de commande de courant convertissant son entrée en alimentation continue appropriée, au moins un dispositif d'éclairage ayant au moins un module électroluminescent qui reçoit l'alimentation continue du circuit de commande de courant pour éclairer avec de l'énergie thermique, et une plaque de base (un dissipateur de chaleur) positionnée dans la région inférieure du ou des dispositifs d'éclairage, la plaque de base étant destinée à recevoir l'énergie thermique d'au moins un dispositif d'éclairage tout en éclairant et la diffusant de façon uniforme, améliorant la recombinaison Auger non radiative, la sortie de chaleur peut être améliorée et le rendement lumineux peut être réduit, ce qui permet de réaliser une diode électroluminescente qui constitue une meilleure source de chaleur.
