Abstract: A method for making a lighting device includes: obtaining a circuit board having one or more light emitting devices; obtaining a housing configured to receive the circuit board; placing the circuit board in the housing; then dispensing a conformal coating material onto the circuit board; allowing the dispensed conformal coating material to spread and level; and curing the conformal coating material to form a cover or lens on the circuit board. A lighting device may include: a housing configured to receive a light emitting circuit and a battery; a light emitting circuit including one or more light emitting diodes mounted to a circuit board; a translucent or transparent conformal lens formed to cover the one or more light emitting diodes; and an electrical switch for selectively energizing the light emitting diodes to produce light. The housing may be in a shape resembling a key.

Abstract: A method for charging a battery may comprise: setting an initial low charge current level; repetitively interrupting charging in a periodic cycle, and: measuring an open circuit battery voltage when charging is interrupted, determining from the open circuit battery voltage a corresponding predetermined charging current; applying the predetermined charging current; and repeating the periodic cycle. A method may also comprise: setting an initial charge current level, measuring the supply voltage, and decreasing the charge current level if the measured supply voltage is less than a predetermined voltage.

Abstract: A portable light includes a base and a light source supported by the base. The base includes at least two deployable legs, wherein the legs cooperate with the base in providing a three point support for the light, e.g., for aiding stability. The at least two deployable legs may include a brace between the legs, wherein the legs when braced cooperate with the base in providing the three point support, e.g., for aiding stability. The portable light may also include a pole on the base and the light source on the pole; and the pole may be a telescoping pole.

Abstract: A portable light includes a base having a deployable pole pivotably supported on the base, and a light source supported on the deployable pole. A latch is configured to retain the deployable pole in a deployed position and to release the deployable pole from the deployed position at which it is retained. The latch includes a latch plate that is biased to move toward the deployable pole to engage a base end thereof when the deployable pole is in the deployed position and that is movable to release the deployable pole.

Abstract: A portable light may comprise: a light body having an illumination, e.g., white, light source and one or more laser light sources, each light source being selectively energizable for producing light; and a switch for selectively energizing the illumination light source and/or the laser light sources. The one or more laser light sources provide diverging narrow beams of laser light, so as to appear as spaced apart dots or spots of laser light on objects illuminated by the beams of laser light. Because the laser light beams diverge, the distance between the dots is proportional to the distance to the object which the dots illuminate. A TIR optical element may also be disposed in front of the illumination light source for receiving the light produced thereby.

Abstract: A portable light may comprise: a light body defining at least a part of a passage, a light source supported by the light body, a switch for controlling the light source, and a deployable hanger for hanging the light from an object. The deployable hanger may comprise: a spring finger proximate the passage, and a hanger ring having at least first and second flat surfaces disposed in the passage and engaging the spring finger. The spring finger bears against the first flat surface of the hanger ring for biasing the hanger ring to a first position and bears against the second flat surface of the hanger ring for biasing the hanger ring to a second position.
