Dental light

A self-ventilating, enclosed, lighting device for dental, medical or the like uses having a frame of predetermined configuration with a light source mounted therein, a transparent shield mounted on and covering an open front thereof, and a light reflector mounted on the back and generally covering the open back. Inlet air passages are formed generally at the front of the device and exit air passages are formed generally at the back of the device. Airflow is created by convection heating of the air by the light source to cause an airflow into the lighting device through the inlet air passages, through the interior of the lighting device and around the light source, and out of the lighting device through the exit air passages for cooling the lighting device. The reflector is preferably pivotally mounted on the frame for being moved between an open position for access to the interior of the lighting device and a closed position during use of the lighting device. Handles are preferably connected to the frame by insulating means for insulating the heat generated in the lighting device from the handles to maintain the handles in a cool condition for touch by the user.
