Abstract
A programmable flashlight with automatic light intensity adjustment means includes a flashlight casing, a light source, a programmable switch, a printed circuit board with a microprocessor coupled thereon, a power source and a sensor component. A light controlling program operable by the microprocessor is adapted to control electrical current passing through the light source according to intensity of incident light as detected by the sensor. A programming program operable by the microprocessor is adapted to control the programming of the functional sequence of the programmable switch and/or the parameters of each of the operation modes by sensing a sequence of ON and OFF light flashes as generated by an external device.

A programmable flashlight with automatic light intensity adjustment means which comprises
- a flashlight casing,
- a light source operable among a plurality of operation modes with each of the operation modes having a plurality of programmable parameters,
- a programmable switch for controlling the light source to switch among the plurality of operation modes according to a functional sequence,
- a printed circuit board with a microprocessor coupled thereon, and
- a power source,
- wherein a sensor component is attached to the flashlight casing, and the sensor component comprises a sensor casing and a sensor disposed therein, and the sensor is electronically connected to the light source, the switch, the printed circuit board and the power source;
- a light controlling program operable by the microprocessor is adapted to control electrical current passing through the light source according to intensity of incident light as detected by the sensor so that more current is passed through the light source when a lower intensity of incident light is detected, and less current is passed through the light source when a higher intensity of incident light is detected;
- a programming program operable by the microprocessor is adapted to
- control the sensor to sense a sequence of ON and OFF light flashes as generated by an external device with the sequence of ON and OFF light flashes being a representation of a binary code signal for programming the functional sequence of the programmable switch and/or the parameters of each of the operation modes,
- decode the sequence of ON and OFF light flashes sensed by the sensor to the corresponding binary code signal, and
- program the functional sequence of the programmable switch and/or the parameters of each of the operation modes with the decoded binary code signal.
