1. An electronic candle, comprising:
- a housing;
an LED light source positioned at least partially within the housing;
a battery for energizing the LED light source;
a microprocessor coupled to the LED light source and programmed to control illumination produced by the LED light source;
a sensor positioned inside the housing to detect a blow of air directed at the electronic candle, the sensor coupled to the microprocessor and including a two-stage electronic circuit that includes one or more transistors and one or more resistors configured to generate a signal in response to detection of the blow and to provide the signal to the microprocessor; and
an additional sensor coupled to the microprocessor and configured to detect a tilt of the electronic candle.

Abstract
An electronic candle includes a housing, an LED light source, a battery, and one or more sensors to detect a blow of air or a tilt of the electronic candle. The electronic candle further includes a microprocessor that is coupled to the LED light source, to the blow sensor and to the tilt sensor. The microprocessor is programmed to control illumination produced by the LED light source, to receive signals indicative of the detection of a blow, and to detect a tilt of the electronic candle.
