PURPOSE: A lighting device is provided to reduce power consumption, to maximize optical efficiency, and to reduce the thickness of a device. CONSTITUTION: A case(10) passes light through a penetrated hole(11) and diffuses light to an outer side through a diffusing part(12). A discharge cover(20) discharges heat in the side of the case. An LED module(30) comprises a power supply part which includes a connecting terminal in a one side. A reflective plate(40) reflects the radiation of an LED. A controller is connected to the LED module and controls an operation according to a preset sequence. |
