Abstract

A wireless headlight assembly for attachment to an eyewear frame is disclosed. The wireless headlight assembly comprises a battery pod containing a battery connected to a lower housing element, which controls the application of power from the battery to an attached headlight assembly containing a headlight.

Claims

1. A cordless headlight assembly comprising:

a headlamp comprising;

a housing; and

a light source, wherein the light source is positioned within the housing; and

a battery assembly, attached to the headlamp, comprising;

a lower assembly comprising;

an electronic assembly configured to control a voltage applied to the light source;

a touch control switch element, electrically connected to the electronic assembly, configured to;

detect a contact of the touch control switch element; and

provide an indication of said detected contact to the electronic assembly, wherein the electronic assembly controls said voltage applied to the light source based on receiving the provided indication; and

a battery pod, attached to the touch control switch element, comprising;

a battery, therein, said battery configured to provide said voltage to the electronic assembly, wherein a connection between the battery pod and the touch control switch element is one of;

a screw thread connection, a bayonet connection, a snap fit connection, a magnet connection, a ball plunger connection, an expanding collar connection and a cam lock coiled spring connection.

2. The assembly of claim 1, further comprising:

a connecting element attached to the lower assembly.

3. The assembly of claim 2, wherein the connecting element is one of:

a “

T-slot”

connector, a slotted connector, and a screw thread connector.

4. The assembly of claim 1, wherein said battery pod is removably attached to the touch control switch element.

5. The assembly of claim 1, wherein the light source comprises:

at least one light emitting diode.

6. The assembly of claim 5, wherein the at least one light emitting diode emits a light in one of:

a ultra-violet light range, a visible light range and an infra-red light range.

7. The assembly of claim 1, wherein the headlamp is pivotally attached to the lower assembly.

8. The assembly of claim 1, wherein the touch control switch element comprises:

a mechanical switch, wherein the contact causes a change in a position of the switch.

9. The assembly of claim 1, wherein the touch control switch element comprises:

a capacitive switch, wherein the contact causes a change in a capacitance of said capacitive switch.

10. An eyewear comprising:

a frame configured to;

attach to a user;

a headlight assembly, attached to the frame, comprising;

a housing comprising;

at least one lighting element;

a battery pod element, attached to the head light assembly, comprising;

a lower element comprising;

a circuit configured to;

control application of a voltage to the at least one lighting element;

a touch control switch element, electrically connected to the circuit, configured to;

detect a touch of the touch control switch element; and

provide an indication of said detected touch to the circuit, wherein the circuit controls application of the voltage to the at least one lighting element based on the provided indication; and

a battery pod, attached to the touch control switch element, comprising;

a battery configured to provide said voltage to the circuit, wherein a connection between the battery pod and the touch control switch element is one of;

a screw thread connection, a bayonet connection, a snap fit connection, a magnet connection, a ball plunger connection, an expanding collar connection and a cam lock coiled spring connection.

11. The eyewear according to claim 10, wherein the frame is selected from one of:

a headband, a monocular assembly, and an eyeglass.

12. The eyewear according to claim 10, wherein the frame comprises:

at least one lens; and

a telescopic lens associated with each of the at least one lens.

13. The eyewear according to claim 12, wherein an orientation of the at least one lighting element is substantially comparable to an orientation of the telescopic lens.

14. The eyewear according to claim 10, wherein the frame comprises a connection element and the headlight assembly comprises a matching connection element.

15. The eyewear according to claim 14, wherein the connection element is a T-slot connector.

16. The eyewear according to claim 15, wherein an orientation of the battery pod is adjustable with respect to the frame.

17. The eyewear according to claim 10, wherein the housing is pivotally attached to the lower assembly.

18. The eyewear according to claim 10, wherein the touch control switch element comprises:

a mechanical switch, wherein the touch causes a change in a state of the switch.

19. The eyewear according to claim 10, wherein the touch control switch element comprises:

a capacitive switch, wherein the touch causes a change in a capacitance of the capacitive switch.
