Appl. No.:

11/335486

Inventors:

Mark W. Snyder - Hockessin DE, US
Norman A. Messinger - Center Square PA, US

Assignee:

Streamlight, Inc. - Eagleville PA

International Classification:

H05B 37/02

US Classification:

315200A, 315224, 315307

Abstract:

An electronic circuit comprises a switching voltage boosting circuit and a current regulating circuit for controlling current flowing through a solid state light source. A control circuit controls the current regulating circuit and the switching voltage boosting circuit to control the magnitude of current flowing through the solid state light source. An error signal produced by the control circuit for controlling the current flowing through the solid state light source may further control the switching voltage boosting circuit.

Filed:

Jun 14, 2010

Appl. No.:

12/814862

Inventors:

Mark W. Snyder - Hockessin DE, US

Assignee:

Streamlight, Inc. - Eagleville PA

International Classification:

H04B 10/00
F21L 4/00

US Classification:

398172, 362157

Abstract:

A system may comprise a portable light and a receiver therefor. The portable light for illuminating may comprise: a light source, a housing supporting the light source, a processor selectively energizing the light source from an electrical power source to produce illumination, a switch controlling the processor, and a memory storing data relating to the portable light, wherein the processor modulates the light source responsive to the stored data. The receiver receiving data transmitted by the portable light may comprise: a receiver housing including a light sensitive receiver receiving data emitted by the light source; and a receiver processor reproducing a representation of the data stored in the memory and providing the decoded received data for perception by a human and/or for use by a computing device.

Appl. No.:

13/428470

Inventors:

Mark W. Snyder - Hockessin DE, US
Raymond L. Sharrah - Collegeville PA, US
Thomas D. Boris - Collegeville PA, US
Brian Orme - Phoenixville PA, US

International Classification:

H05B 37/02
F21L 4/00

US Classification:

315291, 362157

Abstract:

An electronic circuit and/or method that determines a type and/or size of a battery in a light and controls operation of a light source may comprise: a circuit measuring the voltage of the battery; and a processor for determining the measured battery voltage. The processor may compare the measured battery voltage and a predetermined voltage and set an operating condition of the light source based upon the difference between the measured battery voltage and the predetermined voltage. The processor may apply a predetermined load to the battery for a predetermined time and measure battery voltage during the predetermined time; and determine the difference between the measured voltage of the battery and the measured battery voltage during the predetermined time.
