An imitation candle (10) is made from a translucent material (22) having light transmissive properties similar to paraffin. The translucent material (22) is shaped to appear reduced by burning. An LED (24), or similar high intensity light source, is set in a cavity (26) enclosed within translucent material (22). An amber colored LED (24) produces a light similar in color to candle light. The material (22) diffuses the light emitted from the LED (24) to create a warm, natural looking glow. A randomizing energization circuit (46) varies light emission levels from the LED (24) in a pseudo-random manner to simulate the flicker of candle light.

La présente invention concerne une bougie artificielle (10) faite d'un matériau translucide (22) présentant des propriétés de transmission de lumière semblables à la paraffine. Le matériau translucide (22) est profilé pour paraître diminué par la combustion. Une DEL (24), ou une autre source lumineuse de forte intensité semblable, est placée dans une cavité (26) comprise dans le matériau translucide (22). Une DEL de couleur ambrée (24) produit une lumière semblable au niveau des couleurs à la lumière d'une bougie. Le matériau (22) diffuse la lumière émise par la DEL (24) pour créer une incandescence semblant naturelle, chaude. Un circuit d'excitation par randomisation (46) modifie les niveaux d'émission de lumière de la DEL (24) de manière pseudo-aléatoire pour simuler le clignotement de la lumière de bougie.
