The battery holder 45 comprises a spring contact, second contact 17D, a wire 42 forming an electrical connection, a gasket 30 providing a water tight seal, and a hollow compartment 27 as illustrated in FIG. 6 for receiving a 1.5V alkaline type dry cell battery 14 of a C size. However, a rechargeable battery maybe used instead of a dry cell battery 14, and in addition, batteries having sizes other than C maybe used. The assembly of the battery holder 45 includes a contact spring which is fixed therein the end portion of the hollow compartment 27 by an adhesive, and then thereby soldered to the wiring 42 which meets the contact spring via an aperture 19 within the end portion of the hollow compartment 27.

Following the installation of a battery 14, the negative terminal thereof meets the contact spring, allowing for a flow of current from the wiring 42 to the negative terminal of the battery 14. Further, following the installation of the light emitting device 44 the contact spring also urges the battery 14 forward, thereby allowing for a flow of current from the positive terminal of the battery 14 to the upper electrical contact 17A of the light emitting device 44, which is explained in greater detail below. The second contact 17D is fastened within a cavity of the lower front portion of the battery holder 45 by screw or the like. The second contact 17D is then thereby soldered to the wiring 42 completing an electrical connection with the contact spring thereof. The second contact 17D is also configured to provide a resilient force ensuring a constant electrical connection with the lower electrical contact 17B of the light emitting device 44. Concluding the arrangement and assembly of the battery holder 45, the battery holder 45 is fixed within the cavity 24A of the helmet shell by an adhesive, which also provides protection against the elements such as rain or dust.

FIG. 5, illustrates an exploded isometric view of the light emitting device 44 assembly of the present invention. Included is a base 29 which has a upper and lower electrical contact 17A,17B, two cavities 24 configured for receiving the upper and lower electrical contacts 17A,17B, contact modules 13, electrical wiring 42, resistors 49 as illustrated in FIGS. 9A,9B and an aperture 19 upon the front portion of the base 29 provided for receiving the fastening screw 18. The electrical contacts 17A,17B are position therein cavities 24 of the back end portion of the base 29 arranged to align and interact with electrical contacts 17D, and the positive terminal of the battery 14. The electrical contacts 17A,17B are fastened within the cavities 24 by applying an adhesive such as glue. The electrical contacts 17A,17B may be relatively small and square shaped. The electrical contacts 17A,17B are soldered to the electrical wiring 42 via an aperture 19 within the inner back end portion of the cavities 24. The wiring 42 thereof rest upon the surface of the base 29 and is thereby soldered at the opposite end to the terminals of the contact modules 13, thereby forming an electrical connection. The contact module 13 configuration is of the nature to interact with contact pins 10 in a manner to open and close a circuit when choosing a mode of operation thereby activating the LEDs 25A,25B. The contact modules 13 are fastened upon the surface of the base 29 by either an screw or adhesive. The contact modules 13 configuration include positive and negative contacts 17C which are spring loaded thereby allowing for some depression into the contact modules 13 when engaging the contact pins 10. There is also openings configured within the base 29 for receiving the lower bottom portion of the contact modules 13.

Also include is a second housing 36, a light source consisting of Light Emitting Diodes (LEDs) 25A,25B, tension mechanism 15, four contact pins 10 for making electrical contact with the contact modules 13, six apertures 19 for receiving LED 25A,25B terminals, an aperture 19 for receiving the tension mechanism 15, and a hollow portion. The contact pins 10 thereof are inserted therein four apertures 19, extending downward within the hollow portion of the second housing 36. The pins 10 maybe fastened in place by either an adhesive or screwed, provided external threads are present thereon. Following the installment of the contact pins 10, the positive and negative terminals of the LEDs 25A,25B are then thereby inserted within apertures 19, and then thereby soldered to the contact pins 10. The pins 10 provide an electrical path between the LEDs 25A,25B terminals and the fixed contacts 17C of the contact modules 13 when in the selected modes first or second, thereby forming a closed circuit. The LEDs 25A,25B, are activated when in the first mode, upon selecting the second mode LEDs 25A are activated. The top portion of the tension mechanism 15 is inserted within an aperture 19 of the second housing 36 extending downward through the hollow portion thereof, further through an aperture 19B to meet with the bottom portion thereof, thereby coupling the first and second housing 35,36. The aperture 19B and tension mechanism 15 configurations allows for movement of the second housing 36 upon the first housing 35 in a horizontal direction when choosing a mode of operation. The tension mechanism 15 further provides a resilience in which works to secure the device 44 in a chosen mode of operation even when the helmet 26 is jarred or dropped. Furthermore, the tension mechanism 15 may also include a component for which preventing any additional movement that may thereby be inapplicable during installation of the light emitting device 44 to the helmet 26.

The light emitting device 44 assembly further include the fastening of the bulb cover 23 to the second housing 36 by applying an adhesive, providing a permanent bond and water tight seal. The bulb cover 23 configurations provides covering while also providing a contact point by which the user chooses a mode of operation, by urging the bulb cover 23 forward to the first or second mode, and by urging the bulb cover 23 in the opposite direction when choosing the off mode. The bulb cover 23 configurations may include a reflective interior coating and an exterior and interior shape configured to direct light from the helmet 26. The bulb cover 23 maybe formed of a transparent or translucent material enabling light to pass.

Concluding the assembly of the lighting device 44. The base 29 is now thereby fastened to the first housing 35 by applying an adhesive, completing the light emitting device 44 assembly.

Referring now to FIGS. 6-8, the light emitting device 44 is configured to attach and detach to the helmet 26. The device 44 is attached to the helmet 26 by inserting a screw 18 through apertures 19, and then thereby inserting the screw 18 within the fastening hole 21. As illustrated in FIG. 3, the fastening hole 21 is configured within the shell of the helmet 26.

As illustrated in FIGS. 9A and 9B, the hardhat 26 of the present invention has two modes of operation, which include a first and second mode. The first mode activates LEDs 25A which emit light continually forward. The LED 25B is also activated which emits light in a blinking motion. The first mode provides the wearer with lighting while also alerting others of the wearers position. Also, the second mode activate LEDs 25A and deactivates LED 25B.
