<p>PURPOSE: A ventilation system with lighting has excellent energy saving effect in comparison with existing lighting using a safety device and a fluorescent lamp by using a light emitting diode (LED) light. CONSTITUTION: A ventilation system with lighting comprises a circular ventilation main body (10), an air control unit (20), and an LED light (30). The ventilation main body comprises an air path (11), a bracket (12) which is installed on one end of the air path and has a female screw unit, and a light flange (13) installed in the lower part and having an edge part rolled to the upper outer side. The air control unit comprises a screw shaft (21) connected to the female screw unit of the bracket and a control member (22) controlling the discharge amount of the air. The control member reduces the amount of the air discharged through the air path by being moved to the air path in the inner center of the ventilation main body when the screw shaft rotates along the female screw unit of the bracket or increases the amount of the air discharged through the air path as the screw shaft gets far from the air path in the rotation along the female screw unit of the bracket. The LED light is installed in the edge of the light flange and inside the control member controlling the discharge amount of the air.</p> |
