Universal L.E.D. Safety Light for Head-Wear

The current invention involves an improvement over arrangements for putting a light on an existing cap or head-wear component. The invention uses an existing cap's rear end, length-adjustable belt to support the light and thereby save production costs and simplify the structure. One can also, using the same "length-adjustable belt" tooling, provide a single piece of the length-adjustment belt for stitching on the side of the cap or head-wear. Whether on the side or back, the invention adds to any cap an eye-catching light show for use during night time activities or for increasing the fun of outdoor activities in general.

A light device with several light emitting diode or diodes is arranged to be mounted on the soft and flexible belt which is a part of conventional caps, in order to provide length or cap-size adjustment at the rear of the cap. The mounting also can be on a single piece of adjustable length belt which has been stitched on a side of the cap or other location suitable for warning purposes. By using the existing soft/flexible plate material of the length-adjustment belt and by not spending for expensive tooling, a user's safety can be enhanced at low cost while providing lighting at the rear end or side of the cap. The plate or frame design utilizing the length-adjustable belt is easily stitched on any soft material such as cloth, leather, PVC, or wool to form a head-wear.

The LED drivers may be in the form of a conventional electric circuit or an integrated circuit which drives the D.C. power battery to trigger the LED or LEDs and provide a light show. The light show may include flashing, steady, fade-in-out, sequential, or chasing effects. The circuitry is completely conventional, however, and therefore not described in detail herein. The components may include, for example, a diode, transistor, capacitor, integrated circuit, D.C. battery, and switch, all of which are provided on the printed circuit board.

The current invention may be applied to all existing head-wear and provides a brilliant light for personal safety with very low cost. The invention only requires an LED and circuit board with some Velcro.TM. to fix on the inner edge of the conventional cap or head-wear.

The primary object of the present invention is thus to provide a useful illuminated universal LED safety light for head-wear. The objects of the invention will become clearer from an inspection of the detailed description of the invention and from the appended claims.

The preferred universal LED safety light for head-wear shown in FIG. 1 uses an existing rear end "length-adjustable belt" made up of straps (01) and (02), one of which includes projections (40) and the other of which includes holes (41) having diameters approximately the same as the holes for adjusting, as is known, the size of the cap. Strap (02) further includes three round holes (03) for holding several light emitting diodes (04) on one side. By stitching two straps (01) and (02) of the adjustable length belt on the cap itself using separate stitches (05) and (06), a channel (07) can be provided to let wire harness (08) pass through to the inner side of cap to be connected with an electric circuit board (09). Electric circuit board (09) has a built-in D.C. power supply or batteries (10), and a conventional or integrated circuit (11) for triggering the LED (04) to exhibit special effects such as flashing, sequential, random, fade in-out, chasing, etc. One on-off switch (16)is also included on the electric circuit board to provide a system on-off function. The circuit board (09) is attached to the cap by two pieces of Velcro.TM. (12) and (13), one of which is stitched to a proper location in the inner part of the cap and the other of which is attached to the board.

FIG. 3 shows the construction of a revised "adjustable length belt" with several round hole or holes to catch the projections of the other piece. A raised surface (22) is designed for containing the LED or LEDs (04) in holes (23) to fix the LED at a proper location. A back panel (25) covers the wire harness (26) and the portions of the LEDs (64) inside of the raised surface (22) to provide a solid light container with two LED lead wires extending to the electric circuit board.

From FIG. 4, we can easily see how the back plate (30) is held on the rear surface (56) of the adjustable length belt. A lower level recess (27) is provided to keep the back plate at the same level with rear surface (56). Several plastic projections (28) higher than the surface (56) of the belt pass through the holes (29) and are affixed using a soldering gun to melt the projections (28) secure back plate (30) to the belt.

FIG. 5 shows details of the stitches used to hold the "adjustable length belt" made up of straps (01) and (02) on the cap in the manner also illustrated in FIG. 7. Two disconnected stitches on two sides of the belt allow two wire harnesses (32) to pass through the channel and into the inner part of cap to connect with the above-described electric circuit board.

FIG. 6 shows another stitching arrangement for holding a single strap (02) of the "adjustable length belt" on the surface of cap, the stitching extending partially or completely around the edge of the single strap (02)', which can thus be used in a side-mounted lighting arrangement of the type shown in FIG. 8 without the need for extra tooling other than that already used to make the adjustable-length belt.
