Candle emulation

Abstract

A wax candle simulation device with random flicker electric circuitry, comprising at least two miniature light bulbs mechanically vertically closely arranged with the filaments therein arranged at an angle. The bulbs are contained within a flame shaped translucent housing and are connected to an electrical circuitry comprising two transistors, with one driving the other (inverter) with an external control and a switch between them set by resistor values. Additional resistors slow down light bulb shut down and the filaments are constantly pre-heated with a slow cool down, whereby the transition between the lighting of the light bulbs is very gradual. A single counter IC, creates the external driver circuitry with a portion of the IC providing a low stability oscillator and another portion operating as a counter with outputs connected to resistors. The other ends of the resistors are parallel and connected to the inverter. A random selector depends on the counter with the parallel original value of the resistors deciding the start of the inverter, which also depends on value selection, oscillator stability and the number of outputs used. This creates a variety of values which will repeat only several minutes later if the oscillator is stable at the time. The components have low tolerances whereby there are no two candle emulations of the same pattern.
