LIGHTING DEVICE

摘要

PURPOSE: A lighting device is provided to properly arrange light emitting diode modules which have different radiation angles, thereby increasing the brightness of light. CONSTITUTION: A lighting device includes a housing unit(100), a light emitting unit(200), and a cover unit(300). The housing unit includes a base plate(110) which is bent downward. The light emitting unit is placed on the base plate and includes a plurality of light source units which has different light radiation angles according to the installation area of a base plate. The cover unit is placed in the housing to protect the light emitting unit. The light emitting unit includes at least one first light source unit(210), at least one pair of second light source units(220), and at least one par of third light source units. The second light source units have larger light radiation angles than the first and third light source units.
