Abstract
A flashlight having multiple light sources that may be actuated by a user. A first light source located at or near a first end of the flashlight provides a concentrated, linear beam of light from a head module that is generally parallel with the flashlight when the first light source is actuated. A reflector focuses the beam of light. A second light source in combination with a reflector located a tail module, which is at or near a second end of the flashlight, provides radial illumination with respect to the tail module when the second light source is actuated. The reflector diffuses illumination at the tail module. A switching mechanism enables a user to selectively actuate or deactuate the first and/or second light sources.
Claims40
A portable, hand-held flashlight configured to provide generally radial illumination, the flashlight comprising:
- a power source;
- means for containing the power source;
- means electrically coupled to the power source for providing generally radial illumination, wherein the means for providing generally radial illumination comprises means for diffusing the illumination, the means for diffusing the illumination comprising a diffusing reflector configured such that light is reflected away from peripheral surfaces of the diffusing reflector such that the portable, hand-held flashlight emits generally radial illumination, wherein the means for providing generally radial illumination is located at a first portion of the means for containing;
- and wherein the flashlight further comprises:
- means located at a second portion of the means for containing for providing illumination.
A portable, hand-held flashlight configured to provide radial illumination, the flashlight comprising:
- a power source;
- a first light source electrically coupled to the power source, the first light source configured to provide illumination;
- a flashlight housing configured to house the power source and the first light source;
- a reflector housed by the housing, the reflector configured so as to diffuse the illumination of the first light source, the reflector configured such that light from the first light source is reflected away from peripheral surfaces of the diffusing reflector such that the portable, hand-held illumination flashlight emits generally radial illumination and
- a second light source housed by a different portion of the flashlight housing from the first light source.
A portable, hand-held flashlight system comprising:
- a housing;
- a first light source contained within the housing such that the flashlight is configured to provide generally linear illumination;
- a second light source contained within the housing;
- at least one reflector contained within the housing, wherein a combination of the second light source and the reflector provide generally radial illumination, wherein the reflector is a diffusing reflector that is configured such that light from the second light source is reflected away from peripheral surfaces of the diffusing reflector;
- and
- a power supply housed within the housing for selectively providing power to at least one of the first and second light sources.
A portable, hand-held flashlight system comprising:
- a housing:
- a first light source contained within the housing,
- a second light source contained within the housing;
- at least one reflector contained within the housing, wherein a combination of the second light source and the reflector provide generally radial illumination, wherein the reflector is a diffusing reflector that is configured such that light from the second light source is reflected away from peripheral surfaces of the diffusing reflector:
- and
- a power supply housed within the housing for selectively providing power to at least one of the first and second light sources.
- wherein the power source comprises a cartridge that holds at least one battery.
A portable, hand-held flashlight comprising:
- a housing portion;
- a tail module coupled to the housing portion;
- a diffusing reflector mounted within the tail module;
- a light source contained within the tail module such that the light source emits generally radial illumination with respect to the tail module;
- a power source for providing power to the light source, wherein the diffusing reflector is configured such that light from the light source is reflected away from peripheral surfaces of the diffusing reflector;
- and
- a second light source mounted in the housing portion, the second light source configured to receive power from the power source.
A handheld, portable flashlight that provides focused illumination from a first end and/or radial illumination from a second end, the flashlight comprising:
- a portable, electrical circuit;
- at least one battery electrically coupled to the portable electrical circuit;
- a housing configured to contain the portable electrical circuit and the at least one battery;
- a first light source at one end of the housing, the first light source being electrically coupled to the electrical circuit;
- a first reflector positioned adjacent the first light source such that the combination of the first light source and the first reflector provides a generally linear illumination;
- a second light source at an opposing end of the housing;
- and
- a second reflector positioned adjacent the second light source such that the combination of the second light source and the second reflector provides generally diffused illumination, such that the flashlight selectively provides generally linear and/or radial illumination, wherein the second reflector is configured such that light from the light source is reflected away from peripheral surfaces of the diffusing reflector and wherein the diffusing reflector prevents linear illumination through the second reflector.
