Abstract
A heat-dissipating headlamp assembly comprises a housing including a light source such as a light-emitting diode (LED) disposed therein, and a detachable heat shroud covering the rearward portion of the housing. In the preferred embodiment the housing includes a pair of opposing detents, and the detachable heat shroud includes a pair of opposing protrusions that cooperate with the detents to hold the shroud in position. The assembly further includes a mounting bracket extending downwardly from the rearward portion for attachment to a headband, spectacle frames, or other head-worn item, and the heat shroud includes an upper rearward notch to accommodate the electrical cable connected to the light source and a lower rearward notch to accommodate the mounting bracket. The heat shroud is generally cylindrical in shape, and so, too, is the housing, at least where the heat shroud attaches thereto.
