Flashlight
First Claim
1. A flashlight comprising:
- a) a housing having at least one cell and having a transparent lens on a forward end thereof;
b) an LED light source connected to said at least one cell;
c) collimating optics positioned adjacent said LED to refract said rays of light forwardly;
d) a first paraboloid reflector having a concave reflective surface positioned within said housing to receive rays of light from said collimating optics and to reflect said rays rearwardly;
e) a second paraboloid reflector having a concave reflective surface positioned within said housing to receive rays of light reflected rearwardly from said first paraboloid reflector and to further reflect said rays forwardly through said transparent lens.

Abstract
A flashlight is disclosed which includes a housing adapted to receive one or more battery cells and having a transparent lens on a forward end thereof. An LED light source connected to the cell is utilized in conjunction with collimating optics positioned adjacent the LED to refract rays of light from the LED forwardly. A first paraboloid reflector having a concave reflective surface is positioned within said housing to receive rays of light from the collimating optics and to reflect the rays rearwardly and a second paraboloid reflector having a concave reflective surface is positioned within said housing to receive rays of light reflected rearwardly from the first paraboloid reflector and to further reflect the rays forwardly through the transparent lens.

20. A flashlight comprising:
-
a) a housing having at least one cell and having a transparent lens on a forward end thereof;
b) an LED light source connected to said at least one cell, said LED light source when energized emitting rays of light in a generally hemispherical light pattern;
c) collimating optics positioned adjacent said LED to direct said rays of light into a first generally cylindrical pattern of light with light rays being generally parallel to one another and directed in a forward direction along an optical axis;
d) a first paraboloid reflector having a concave reflective surface attached to an inner side of said transparent lens, said first paraboloid reflector having a focus point positioned on said optical axis and positioned to receive rays of light from said collimating optics and first generally cylindrical pattern of light and to reflect said rays rearwardly generally through said focus point; and
e) a second paraboloid reflector having a concave reflective surface positioned within said housing and having a focus point positioned on said optical axis to receive rays of light reflected rearwardly from said first paraboloid reflector and to further reflect said rays into a second generally cylindrical pattern of light with light rays being generally parallel to one another and directed in a forward direction along an optical axis and out of the housing through said transparent lens. - View Dependent Claims (21)
