Heat warning safety device using light emitting diodes
First Claim
1. A heat alert safety device for warning individuals that a surface of a stove containing two or more heating elements may be hot, comprising:
- (a) a controller (b) a source of electric power (c) for each heating element on the surface, a heat sensor beneath the surface and adjacent the heating element for ascertaining and communicating the temperature of the heating element to the controller, a plurality of light emitting diodes adjacent the heating element, the plurality of light emitting diodes configured to represent a predetermined heat warning symbol, said symbol alone communicating that the surface is dangerously hot, the symbol readily visible only when illuminated to an observer who can also readily see the surface, the source of electric power in electric communication with the plurality of light emitting diodes so that the light emitting diodes can be illuminated, the controller capable of receiving temperature information from the heat sensors and controlling the light emitting diodes so that whenever a specified surface temperature of a particular heating element is reached, the symbol is illuminated and remains illuminated as long as the specified surface temperature of that heating element is maintained, the heat warning symbols positioned so that an observer approaching a heating element of the stove from any direction when said heating element is dangerously hot can readily see and understand the heat warning symbol of that heating element.

Abstract
Heat alert safety device for warning individuals that a surface containing multiple heating elements has residual heat wherein a configuration of light emitting diodes that comprises a heat warning symbol specific that one heating element receives electric power whenever a specified temperature of that heating element is exceeded. A controller of the LEDs receives information from a heat sensor adjacent the heating element. The symbols are positioned so that an observer approaching a heating element of the stove from any direction when the heating element is dangerously hot can readily see and understand the heat warning symbol for that heating element. In one embodiment, the heat warning symbol comprises an arrangement of LED'"'"'s that forms a perimeter around the heating element interrupted by the letters “HOT” or partially encircles the heating element but is positioned between the heating element and an observer approaching the heating element. The warning device is adjustable for brightness and incorporates sound and blinking.
