PURPOSE: An LED module for a lighting device is provided to increase diffusion diameter of the light by reducing an incline of mounting parts from a central part to an outer part. CONSTITUTION: An LED module for a lighting device includes a circuit board(10), a plurality of mounting units(20), and a plurality of LED chips(30). The plurality of mounting parts are made of copper foil and include a central mounting part(21) and peripheral mounting parts(22). The central mounting part is arranged in the central part of the circuit board. The peripheral mounting parts are arranged around the central mounting part and are horizontally patterned by the etching. The incline of the peripheral mounting parts is reduced to the outer part from the central part of the circuit board. The plurality of LED chips are mounted on the plurality of mounting parts. |
