Abstract

A portable light comprises: a light body extending from a light head, one or more light sources supported by the light head and energizable to produce light, and one or more switches for selectively energizing the light sources. In one embodiment, the one or more switches are at substantially diametrically opposite locations on the light body, and plural light emitting sources and/or a light emitting source and a laser light source may be provided. In another embodiment, the light body defines an envelope line extending along a side thereof and has a recess inward of the envelope line. A clip may be configured to be disposed substantially in the recess of the light body and within the envelope line of the light body.

First claim

What is claimed is:

1 . A portable light comprising:
a light body defining a longitudinal axis and including a light head at a first end thereof and a light housing extending away from said light head; said light housing having an internal cavity for receiving a source of electrical power; a first light source supported by said light head and energizable to produce light directed outwardly from said light head substantially along the longitudinal axis; a first actuator at a first location on a half of said light body proximate said first end for selectively energizing said first light source to produce light; a second light source supported by said light head and energizable to produce light directed outwardly from said light head; a second actuator at a second location on the half of said light body proximate said first end for selectively energizing said second light source to produce light, wherein said second actuator is supported on said light body substantially diametrically opposite to said first actuator.

2 . The portable light of claim 1 wherein said second light source includes:
a light emitting diode energizable to produce light directed substantially transversely to the longitudinal axis; or
a laser light source energizable to produce light directed outwardly from said light head substantially along the longitudinal axis.

3 . The portable light of claim 1 wherein:
said light body has an opening through which light produced by said second light source passes in a direction substantially transverse to the longitudinal axis, and
said second actuator is supported on said light body adjacent to the opening in said light body for the light produced by said second light source.

4 . The portable light of claim 3 further comprising a lens in the opening in said light body. wherein said second actuator is supported on said light body immediately rearward of said lens.

5 . The portable light of claim 1 further comprising a cover, wherein said light body has an opening in a side thereof in which said cover is disposed, wherein:
if said second light source includes a light emitting diode energizable to produce light directed substantially transversely to the longitudinal axis, then said cover disposed in the opening is a lens through which light produced by said light emitting diode passes in a direction substantially transverse to the longitudinal axis; or
if said second light source includes a laser light source energizable to produce light directed outwardly from said light head substantially along the longitudinal axis, then said cover disposed in the opening provides a notice regarding said laser light source.

6 . The portable light of claim 1 wherein said light housing defines an envelope line extending along a side thereof away from said light head along a side of said light housing, said light housing having a recess in the side thereof inward of the envelope line; said portable light further comprising:
a clip disposed in the recess of said light housing, wherein the shape and size of the recess and the shape and size of said clip are configured so that said clip is substantially in the recess and substantially within the envelope line of said light housing,
whereby said clip does not extend substantially beyond the envelope of said portable light where it could catch on or snag an external object.

7 . The portable light of claim 6 wherein:
said clip is pivotable relative to said light housing; or
said clip is biased to pivot towards said light housing; or
said clip is proximate an end of said light housing distal said light head; or
said clip is located on a side of said light body opposite to a side of said light body that supports said second actuator; or
any combination of the foregoing.

8 . The portable light of claim 6 wherein said source of electrical power includes plural sources of electrical power, and wherein the internal cavity is configured to receive fewer of the plural sources of electrical power in side by side arrangement in a first location in the cavity adjacent the recess than at another location in the cavity.

9 . The portable light of claim 1 wherein said first light source produces a spot beam and said second light source produces a flood beam.

10 . The portable light of claim 1 wherein said first actuator actuates a first electrical switch for selectively energizing said first light source and said second actuator actuates a second electrical switch for selectively energizing said second light source.

11 . The portable light of claim 1 further comprising a first resistance in series with said first light source and a second resistance in series with said second light source, wherein:
said first resistance and said second resistance each have a respective ohmic value to render said portable light intrinsically safe; or
said first resistance and said second resistance each include a fuse, or
said first resistance and said second resistance each include a fuse and have a respective ohmic value to render said portable light intrinsically safe.

12 . A portable light comprising:
a light body defining a longitudinal axis and including a light head at a first end thereof and a light housing extending away from said light head; said light housing having an internal cavity for receiving a source of electrical power; a first light source supported by said light head and energizable to produce light directed outwardly substantially along the longitudinal axis; a first actuator for selectively energizing said first light source to produce light; a second light source supported by said light head and energizable to produce light directed outwardly substantially transversely to the longitudinal axis through an opening in said light body; a second actuator for selectively energizing said second light source to produce light, wherein said second actuator is supported on said light body adjacent to the opening in said light body for light produced by said second light source; and wherein said first actuator is supported on said light body substantially diametrically opposite to said second actuator.

13 . The portable light of claim 12 wherein said second light source includes:
a light emitting diode energizable to produce the light directed substantially transversely to the longitudinal axis.

14 . The portable light of claim 12 wherein:
said second actuator is supported on said light body adjacent to the opening in said light body for the light produced by said second light source.

15 . The portable light of claim 12 further comprising a lens in the opening in said light body through which the light produced by said second light source passes in a direction substantially transverse to the longitudinal axis.

16 . The portable light of claim 12 wherein said light housing defines an envelope line extending along a side thereof away from said light head along a side of said light housing, said light housing having a recess in the side thereof inward of the envelope line; said portable light further comprising:
a clip disposed in the recess of said light housing, wherein the shape and size of the recess and the shape and size of said clip are configured so that said clip is substantially in the recess and substantially within the envelope line of said light housing,
whereby said clip does not extend substantially beyond the envelope of said portable light where it could catch on or snag an external object.

17 . The portable light of claim 16 wherein:
said clip is pivotab
