Abstract
A flashlight includes a light assembly at a first end of the flashlight. The light assembly includes an LED light generating module. The flashlight also includes a power assembly having a power management module body member which houses a charging input port, a USB output port, a LED power indicator, or a power indicator button. A selectively movable sleeve covers the charging input port, the USB output port, the LED power indicator, or the power indicator button when they are not in use, wherein the sleeve moves relative to the power management module body member in linear and rotational directions. The flashlight also includes a central body member between the light assembly and the power assembly.
Claims18
A flashlight, comprising:
- a light assembly at a first end of the flashlight, the light assembly including an LED light generating module;
- a power assembly including a power management module body member which houses a charging input port, a USB output port, a LED power indicator, or a power indicator button, a selectively movable sleeve covers the charging input port, the USB output port, the LED power indicator, or the power indicator button when they are not in use, wherein the sleeve moves relative to the power management module body member in linear and rotational directions;
- a central body member between the light assembly and the power assembly;
- and
- wherein movement of the sleeve is controlled via L-shaped grooves formed along an inner surface of the sleeve and mating track balls formed along an outer surface of the power management module body member of the power assembly.
2 more elements
A flashlight operated with either a rechargeable lithium ion battery or an alkaline battery, comprising:
- a light assembly at a first end of the flashlight, the light assembly including an LED light generating module;
- a power assembly at a second end of the flashlight, the power assembly including at least one of a charging input port, a USB output port, a LED power indicator, and a power indicator button, the power assembly further including circuitry for use in conjunction with either a rechargeable lithium ion battery or an alkaline battery, and the power assembly also including an electrical contact assembly with a central first electrical contact, a second electrical contact on one side of the first contact, and a third contact on an opposite side of the central first electrical contact, which all contact a first end of a battery;
- a contact formed along a second end of the LED light generating module, opposite the contact assembly, which contacts a second end of the battery opposite the first end of the battery;
- wherein when the battery is a rechargeable lithium ion battery, the central first electrical contact is engaged with a negative contact of the rechargeable lithium ion battery and the second electrical contact and third contact are engaged with a positive contact of the rechargeable lithium ion battery, and when the battery is an alkaline battery the central first electrical contact is engaged with a negative contact of the alkaline battery, the second electrical contact and third inactive contact are not in engagement with a contact of the alkaline battery, and the contact formed along the second end of the LED light generating module is engaged a positive contact of the alkaline battery;
- and
- a central body member between the light assembly and the power assembly.
