Wearable headlight devices and related methods

A method of operating a headlight device, the method comprising:

• providing a headlight device comprising:
• a luminaire comprising:
• a luminaire housing comprising a first end, a second end opposing the first end, and a heat sinking chamber disposed therebetween, wherein a plurality of luminaire vents are disposed in a ring about the heat sinking chamber of the luminaire housing;
• an optical assembly disposed in the first end of the luminaire housing;
• a heat sink and a light source disposed in the heat sinking chamber of the luminaire housing;
• a venting tube extending from the second end of the luminaire housing;
• an air moving device provided outside of the luminaire housing;
• and
• an exhaust tube connecting the venting tube and the air moving device;
• and
• generating an airflow by the pulling air into the plurality of luminaire vents via the air moving device;
• controlling a temperature of the light source by flowing the air through the luminaire vent and over the heat sink thereby heating the air;
• expressing heated air from the luminaire housing via the venting tube;
• flowing heated air from the venting tube into the exhaust tube and through the exhaust tube to the air moving device;
• and
• expelling the heated air out through the air moving device, which is disposed outside of the luminaire.

A headlight device comprising:

• a luminaire disposed proximate a front portion of the headlight device, the luminaire comprising:
• a luminaire housing comprising a first end, a second end opposing the first end, and a heat sinking chamber disposed therebetween, wherein a plurality of luminaire vents are disposed in a ring about the heat sinking chamber of the luminaire housing;
• an optical assembly disposed in the first end of the luminaire housing;
• a heat sink and a light source disposed in the heat sinking chamber of the luminaire housing;
• and
• a venting tube extending from the second end of luminaire housing;
• an air moving device disposed proximate a rear portion of the headlight device which at least partially opposes the front portion, the air moving device also being disposed outside of the luminaire housing and configured to generate an airflow by pulling air into the luminaire via the plurality of luminaire vents, moving the pulled air across the heat sink thereby heating the air, and expelling the heated air from the rear portion of the device;
• and
• an exhaust tube connecting the venting tube extending from the luminaire to the air moving device to facilitate air flow of the heated air from the heat sink in the front portion of the device to the rear portion of the device to expel the heated air.
