Patent ID: 8651714

Claim:
A portable lighting device configured to be attachable to a helmet or bicycle frame, comprising: a housing configured to fit within the palm of a hand, and further includes a slot for attachment to the helmet or bicycle frame, and one or more air vents in the housing to provide air flow to an interior of the housing for cooling; a pair of high brightness light-emitting diode sets (Hi-LEDs) are contained within the housing to project light from a front surface of the housing, while being cooled by air flow from the one or more air vents; one or more regular light-emitting diodes (LEDs) contained within the housing to project light from an upper exterior surface of the housing; electrical circuitry including a processor and a memory, the electrical circuitry is contained within the housing and is configured to operate respectively the Hi-LEDs and the regular LEDs; and two user-input interfaces configured to be operatively mounted on the upper exterior surface of the housing adjacent the regular LEDs, wherein the memory is an electrically erasable programmable read-only memory (EEPROM) storing two or more brightness level settings for the Hi-LEDs, including a bicycle mode of operation and a special non-bicycle mode of operation, further wherein the EEPROM is configured to be reprogrammable by a user to store at least one different brightness level settings for the Hi-LEDs in response to the user operating at least one of the user-input interfaces and the Hi-LEDs can provide a brightness of at least 1000 lumens.
