Abstract

A light-weight headlamp has a housing containing at least one SMD LED mounted to a circuit board on an inner housing made of thermally non-conductive material fixed to and disposed partly in a pivot mount. The pivot mount is pivotally connected to a mount assembly that is connected by one or more straps to a power source housing containing an electrical power source. The straps hold the mount assembly and power source housing to a users head and a wire connects the power source to the SMD LED. A shield disposed partly in the pivot mount is slidably engaged over the inner housing. A bezel with lens is connected to the shield and changes the shape of a light beam from the SMD LED as the shield slides on the inner housing.

First claim

What is claimed is:

1 . A light-weight headlamp comprising:
a light source housing ( 12 ) containing at least one SMD LED ( 122 ) for generating light when energized; a mount assembly ( 14 ) for pivotally carrying the light source housing; a power source housing ( 16 ) adapted to containing an electrical power source; at least one strap ( 18 , 20 ) connected between the mount assembly ( 14 ) and the power source housing ( 16 ) and adapted to hold the mount assembly and the power source housing to a users head; and a connecting wire ( 24 ) for electrically connecting the power source housing ( 16 ) to the SMD LED for energizing the SMD LED with electrical power from the power source in the power source housing to generate light; the light source housing ( 12 ) comprising:
a rear pivot mount ( 113 ) pivotally connected to the mount assembly ( 14 ) and defining an interior volume;
an inner housing ( 116 ) made of thermally non-conductive material disposed at least partly in the interior volume and having a rear end fixed to the pivot mount ( 113 );
a shield ( 114 ) disposed at least partly in the interior volume and slidably engaged over the inner housing ( 116 );
a circuit board ( 117 ) having a front surface to which the SMD LED is mounted and a rear surface engaged to a front end of the inner housing ( 116 );
a bezel ( 120 ) connected to a front end of the shield ( 114 ); and
a lens ( 120 ) in the bezel for focusing light from the SMD LED.

2 . The light-weight headlamp of claim 1 , wherein the bezel is made of thermally non-conductive material.

3 . The light-weight headlamp of claim 1 , wherein the shield is made of thermally non-conductive material.

4 . The light-weight headlamp of claim 1 , wherein the bezel is made of thermally non-conductive material in the form of ABS.

5 . The light-weight headlamp of claim 1 , wherein the shield is made of thermally non-conductive material in the form of ABS.

6 . The light-weight headlamp of claim 1 , wherein the thermally non-conductive material of the inner housing is ABS.

7 . The light-weight headlamp of claim 1 , wherein the inner housing and the shield are cylindrical.

8 . The light-weight headlamp of claim 1 , wherein the inner housing and the shield are cylindrical and are both made of thermally non-conductive material.

9 . The light-weight headlamp of claim 1 , wherein the inner housing and the shield are cylindrical and are both made of thermally non-conductive material in the form of ABS.

10 . A light-weight headlamp comprising:
a light source housing ( 12 ) containing at least one SMD LED for generating light when energized, the light source housing ( 12 ) comprising: a rear pivot mount ( 113 ) defining an interior volume; a cylindrical inner housing ( 116 ) made of thermally non-conductive material disposed at least partly in the interior volume and having a rear end fixed to the pivot mount ( 113 ); a cylindrical shield ( 114 ) disposed at least partly in the interior volume and slidably engaged over the inner housing ( 116 ); a circuit board ( 117 ) having a front surface to which the SMD LED is mounted and a rear surface engaged to a front end of the inner housing ( 116 ); a bezel ( 120 ) connected to a front end of the shield ( 114 ); and a lens ( 120 ) in the bezel for focusing light from the SMD LED; a mount assembly ( 14 ) for pivotally carrying the pivot mount ( 113 ) of the and light source housing ( 12 ); a power source housing ( 16 ) adapted to containing an electrical power source; at least one strap ( 18 , 20 ) connected between the mount assembly ( 14 ) and the power source housing ( 16 ) and adapted to hold the mount assembly and the power source housing to a users head; and a connecting wire ( 24 ) for electrically connecting the power source housing ( 16 ) to the SMD LED for energizing the SMD LED with electrical power from the power source in the power source housing to generate light.

12 . The light-weight headlamp of claim 10 , wherein the bezel is made of thermally non-conductive material.

13 . The light-weight headlamp of claim 10 , wherein the shield is made of thermally non-conductive material.

14 . The light-weight headlamp of claim 10 , wherein the bezel is made of thermally non-conductive material in the form of ABS.

15 . The light-weight headlamp of claim 10 , wherein the shield is made of thermally non-conductive material in the form of ABS.

16 . The light-weight headlamp of claim 10 , wherein the thermally non-conductive material of the inner housing is ABS.
