Portable lighting device with an illuminated indicia
The invention provides a portable lighting device with an elongated main body that includes a housing with receiver, and a power source positioned within the receiver. An operational mode selector assembly with a switch assembly that is actuated by a user is operatively coupled to the power source. An illumination assembly is electrically coupled to both the operational mode selector and the power source. The illumination assembly has a primary light source with a light emitter that emits light axially along a longitudinal axis of the main body or housing through a lens. A secondary light source with a light emitter emits light substantially perpendicular to the axis to illuminate an indicia located in a side region of the illumination assembly. During operation of the portable lighting device, the components of the illumination assembly are arranged such that: (i) the primary light source does not illuminate the indicia, (ii) the secondary light source does not emit light through the lens, (iii) an appreciable amount of light emitted from the primary light source does not mix with light that is emitted from the secondary light source within the portable lighting device, and (iv) an appreciable amount of light emitted from the secondary light source does not mix with light that is emitted from the primary light source within the portable lighting device.

5. The portable lighting device of claim 1 , wherein the indicia is formed within a removable panel that is positioned radially outward of a collimator residing within the illumination assembly and proximate the lens.
6. The portable lighting device of claim 1 , wherein the illumination assembly further includes:
a indicia panel retainer with an outer surface and a indicia aperture,
a panel with an outer surface, and
wherein, when the panel is inserted within the indicia aperture, the outer surface of the indicia panel retainer and the outer surface of the panel are substantially flush with each other.
7. The portable lighting device of claim 6 , wherein the illumination assembly further includes an illumination housing with an inner surface and an indicia opening; and
wherein an extent of the outer surface of the panel is positioned against the inner surface of the illumination housing and the indicia is positioned within the indicia opening of the illumination housing.
8. The portable lighting device of claim 1 , wherein the secondary light source is comprised of a plurality of light emitters that are arranged radially outward of the primary light source.
9. The portable lighting device of claim 1 , wherein the indicia is defined by an opening that is formed through an extent of the portable lighting device that is located outward of the secondary lighting source.
10. The portable lighting device of claim 1 , wherein a lumen output from the primary light source is greater than a lumen output from the secondary light source.
11. A flashlight comprising:
a main body that includes a receiver;
a power source positioned within the receiver of the main body;
an operational mode selector assembly with a switch assembly that is operatively coupled to the power source;
an illumination assembly electrically coupled to both the operational mode selector and the power source, the illumination assembly having:
a primary light source with a light emitter configured to emit light in a substantially axial direction through a lens,
a secondary light source with a light emitter configured to illuminate an indicia formed in a side region of the illumination assembly, and
wherein, during operation of the portable lighting device: (i) the primary light source does not illuminate the indicia and (ii) the secondary light source does not emit light through the lens.
12. The flashlight of claim 11 , wherein the illumination assembly includes a collimator that prevents: (i) an appreciable amount of light emitted from the secondary light source from mixing with light that is emitted from the primary light source within the portable lighting device, and (ii) an appreciable amount of light emitted from the primary light source from mixing with light that is emitted from the secondary light source within the portable lighting device.
13. The flashlight of claim 11 , wherein the indicia is formed within a removable panel that is positioned radially outward of a collimator residing within the illumination assembly and proximate the lens.
14. The flashlight of claim 11 , wherein the illumination assembly further includes:
a indicia panel retainer with an outer surface and a indicia aperture,
a panel with an outer surface, and
wherein, when the panel is inserted within the indicia aperture, the outer surface of the indicia panel retainer and the outer surface of the panel are substantially flush with each other.
15. The flashlight of claim 14 , wherein the illumination assembly further includes an illumination housing with an inner surface and an indicia opening; and
wherein an extent of the outer surface of the panel is positioned against the inner surface of the illumination housing and the indicia is positioned within the indicia opening of the illumination housing.
16. The flashlight of claim 11 , wherein the secondary light source is comprised of a plurality of light emitters that are arranged radially outward of the primary light source.
17. The flashlight of claim 11 , wherein the indicia is defined by an opening that is formed through an extent of the portable lighting device that is located outward of the secondary lighting source.
18. The flashlight of claim 11 , wherein a lumen output from the primary light source is greater than a lumen output from the secondary light source.
