Abstract

Lighted headgear is provided to enable clear vision in poorly lit locations. The lighted headgear has lights, such as LEDs that generate narrow light beam cones. The headgear is preferably a baseball-type hat with the LEDs secured in small notches in the forward edge of the brim, or in light modules attached toward the brim forward edge. The lights can be similarly provided with a variety of other headgear types including rigid safety hats and rigid fire fighters helmets to name a few. In one form, the lights are positioned so that their respective light beam cones overlap to provide high brightness light in a conical overlap area that can be in the range of normal reading distances or at other distances depending on the intended use of the hat.

2. The lighted hat of claim 1 wherein the rear head-fitting portion includes a power source attached thereto and layers of material, and

electrical leads connected to the light emitting diodes that extend between the brim insert and the fabric material of the brim portion and between the material layers of the head fitting portion to the power source so that the leads are concealed from view for substantially the entire length thereof.

3. The lighted hat of claim 1 wherein the rear head-fitting portion comprises a crown portion of the hat having an adjustment strap at the rear thereof, and

a power module mounted to the strap including an actuator switch for selectively powering the light emitting diodes on and off.

4. The lighted hat of claim 1 wherein the pair of light emitting diodes each include a lens portion, and

compact light modules for the light emitting diodes each including a power source for the light emitting diode mounted therein, a user-operated on/off switch for selectively powering the diodes, and forward facing opening through which the lens portions of the diode projects adjacent the brim front edge portion for projecting light forwardly therefrom.

5. The lighted hat of claim 1 wherein the brim insert includes a pair of small, forwardly opening notches at the front edge portion thereof in which the pair of small, light emitting diodes are secured, and the fabric material includes a pair of cut-outs aligned with the brim insert notches so that the diodes can project therethrough.

6. The lighted hat of claim 5 wherein the head fitting portion includes an adjustment strap and a power source mounted to the adjustment strap.

7. The lighted hat of claim 1 including a power source and power supply medium for the light emitting diodes mounted to the head fitting and brim portions so as to avoid significant increase to the thickness of the brim portion.

8. The lighted hat of claim 7 wherein the head fitting portion includes an adjustment strap to which the power source is attached, the power supply medium includes electrical leads routed from the power source to the light emitting diodes between the fabric material and insert of the brim portion at the front edge thereof.

9. The light hat of claim 1 wherein the head fitting portion comprises a crown defining an interior space with the crown sized to fit snugly on a wearer'"'"'s head received in the interior space, and

a power source mounted to the crown external of the interior space thereof to keep the interior space free from obstruction for optimizing the fit and comfort of the crown when worn on a head.

10. The lighted hat of claim 1 including at least one thin photovoltaic cell for generating power for the light emitting diodes.

11. Headgear, comprising:

a crown for covering the wearers head, having opposed forward and rearward parts;

a brim forwardly extending from the forward part of the crown;

a housing attached to the rearward part of the crown;

an interruptible energy source disposed in the housing for energizing the lamp; and

electrical conductors coupling the lamp to the interruptible energy source.

12. The headgear of claim 11 further comprising a second lamp laterally adjacent the said lamp and received in the brim so as to be at least partly disposed between the upper and the lower surfaces of the brim.

13. The headgear of claim 12 wherein the brim defines notches for receiving the lamps in close fitting relationship so as to orient the direction of light emanating from the lamps.

14. The headgear of claim 13 wherein the lamps comprise wherein the lights are high intensity light-emitting diodes of a predetermined material so that the predetermined lighted area is generated by a narrow light beam.

15. The headgear of claim 12 wherein the lamp emits predetermined lighted areas each having a conical shape with the conical areas intersecting at a predetermined distance within a predetermined distance range so that the overlapping lighted area increases in size with increasing distance from the wearer'"'"'s face to minimize effects of light dissipation in the predetermined distance range.

16. The headgear of claim 14 wherein the interruptible energy source includes a power supply for energizing the lamps and a switch carried on the housing for selectively interrupting energization of the lamp.

17. The headgear of claim 16 wherein the power supply comprises at least one small disc-shaped battery power supply for the lamps to allow the housings to be compactly sized with each of the light-emitting diodes and the battery power supply therefor self-contained in respective ones of the housings.
