<p>PURPOSE: A dimming device for an LED lamp is provided to reduce the number of components by simultaneously controlling a plurality of LED lamps through one dimming unit. CONSTITUTION: The dimming device includes a rectifying unit(100), a dimming unit(200), and a plurality of LED driving units. The rectifying unit rectifies AC power to DC power. The dimming unit transforms the power provided from the rectifying unit to a voltage with a preset level. The plurality of LED driving units are connected in parallel to the dimming unit. The LED driving unit drives the LED lamp by converting the current flowing in an LED lamp(400) based on the voltage applied from the dimming unit.</p> |
