Abstract
The present invention discloses unique flashlight head construction that includes an array of lighting elements individually arranged in a corresponding array of reflector cups. Each lighting element in the flashlight head of the present invention is individually contained within a single reflector cup that both collects and directs the emitted light while protecting the lighting element from damage. Further, the present invention provides a unique structure that facilitates the sealing of the flashlight head to enhance the manufacture of a durable and waterproof flashlight.
Claims20
A flashlight assembly comprising:
- a housing having a bottom wall and a side wall extending upwardly from said bottom wall, an electrically conductive path extending from said bottom wall upwardly along said side wall and a threaded opening opposite said bottom wall;
- a battery having a first contact and a second contact said battery received within said housing wherein said first contact is in electrical communication with electrically conductive path;
- a flashlight head, said flashlight head including,
- a tubular enclosure having a side wall, and an end wall, wherein inner surfaces of said end wall and said side wall cooperate to define said tubular enclosure having an open end, said end wall having at least one inwardly extending aperture,
- a mounting board received in said open end of said enclosure, and
- at least one LED mounted on said inner surface said mounting board having first and second contact leads, said first contact lead in electrical communication with said first contact of said battery, said at least one LED being slideably received within said at least one aperture in said end wall;
- and
- a switch assembly disposed between said second contact lead of said LED and said second contact of said battery, said switch assembly being operable to selectively energize said lighting element.

An LED flashlight comprising:
- a tubular housing having a bottom wall and a side wall extending upwardly from said bottom wall;
- a battery having a first contact and a second contact said battery received within said housing;
- a flashlight head connected to said tubular housing opposite said bottom wall, said flashlight head including,
- a tubular side wall having an inner and outer surface,
- an end wall having an inner and outer surface, wherein said inner surfaces of said end wall and said side wall cooperate to define an open end of said enclosure and said outer surfaces of said end wall and said side wall cooperate to form an outer surface of said assembly, and
- at least one inwardly extending bore in said end wall, said bore having a side wall which is integrally merged with said outer surface of said end wall,
- a mounting board received in said open end of said enclosure, said mounting board having electrical contacts thereon, said contacts in electrical communication with said first and second battery contacts, and
- at least one LED mounted on said mounting board, said at least one LED being slideably received within said at least one bore in said end wall such that said LED is exposed to the exterior environment surrounding said assembly;
- and
- a switch assembly disposed between one of said battery contacts and one of said electrical contacts on said mounting boars, said switch assembly being operable to selectively energize said LED.
