Flashlight with multiple light sources
The present disclosure generally relates to lights and flashlights, and more specifically to a handheld flashlight which has at least two LED light sources and the ability to change between the light sources by twisting the head portion of the flashlight.
1. A flashlight assembly comprising:
a housing;
a yoke assembly comprising,
a yoke body affixed to the housing, said yoke body having a central axis, and a transverse guide slot,
a yoke plate slidably captured in the transverse guide slot, said yoke plate further including a drive slot, and
a first LED and a second LED both mounted to said yoke plate in spaced relation and aligned with the transverse guide slot; and
a head assembly rotatably assembled with the housing and having a focal axis coaxially aligned with said yoke central axis,
said yoke plate being slidably movable between at least a first position wherein said first LED is aligned with said focal axis, and a second position wherein said second LED is aligned with said focal axis,
said head assembly including a drive pin extending from a rearward end thereof and axially offset from said focal axis,
said drive pin engaging said drive slot in said yoke plate wherein rotation of said head assembly relative to said yoke assembly causes a corresponding sliding movement of said yoke plate between said first and second positions.
2. The flashlight assembly of claim 1 wherein said guide slot encompasses a transverse line extending across said yoke body and through said central axis.
3. The flashlight assembly of claim 2 wherein said drive slot is offset from said central axis and extends perpendicular to said transverse line.
4. The flashlight assembly of claim 2 wherein said first LED and said second LED are aligned on said transverse line.
5. The flashlight assembly of claim 3 wherein said first LED and said second LED are aligned on said transverse line.
6. The flashlight assembly of claim 1 wherein said head assembly includes a reflector cup, said reflector cup defining said focal axis.
7. The flashlight assembly of claim 2 wherein said head assembly includes a reflector cup, said reflector cup defining said focal axis.
8. The flashlight assembly of claim 4 wherein said head assembly includes a reflector cup, said reflector cup defining said focal axis.
9. The flashlight assembly of claim 1 further comprising a receiver ring secured to an upper end of said housing, said yoke body affixed to said receiver ring.
10. The flashlight assembly of claim 9 , further comprising a grip ring secured about said head assembly and rotatably received about the upper end of said housing and said receiver ring.
11. The flashlight assembly of claim 1 wherein said yoke body further comprises an arcuate detent slot, and said head assembly including a detent pin which rides within said detent slot, said detent slot having detents therein to define said first and second positions.
12. A flashlight assembly comprising:
a housing;
a power source within the housing;
a yoke assembly comprising,
a yoke body affixed to the housing, said yoke body having a central axis, an upper surface and a transverse guide slot extending across said upper surface and encompassing a transverse line extending through said central axis,
a yoke plate slidably captured in the transverse guide slot, said yoke plate further including a drive slot offset from said central axis and extending perpendicular to said transverse line, and
a first LED and a second LED both mounted to said yoke plate in spaced relation and aligned on said transverse line; and
a head assembly including a reflector cup having a focal axis, said head assembly being received in assembled relation with said housing, said focal axis being coaxially aligned with said yoke central axis,
said yoke plate being slidably movable between at least a first position wherein said first LED is aligned with said focal axis, and a second position wherein said second LED is aligned with said focal axis,
said head assembly including a drive pin extending from a rearward end thereof and axially offset from said focal axis,
said drive pin engaging said drive slot in said yoke plate wherein rotation of said head assembly relative to said yoke assembly causes a corresponding sliding movement of said yoke plate between said first and second positions.
13. The flashlight assembly of claim 12 further comprising a receiver ring secured to an upper end of said housing, said yoke body affixed to said receiver ring.
14. The flashlight assembly of claim 13 , further comprising a grip ring secured about said head assembly and rotatably received about the upper end of said housing and said receiver ring.
15. The flashlight assembly of claim 11 wherein said yoke body further comprises an arcuate detent slot, and said head assembly including a detent pin which rides within said detent slot, said detent slot having detents therein to define said first and second positions.
16. The flashlight assembly of claim 12 wherein said yoke body further comprises an arcuate detent slot, and said head assembly including a detent pin which rides within said detent slot, said detent slot having detents therein to define said first and second positions.
17. The flashlight assembly of claim 13 wherein said yoke body further comprises an arcuate detent slot, and said head assembly including a detent pin which rides within said detent slot, said detent slot having detents therein to define said first and second positions.
