PURPOSE: An LED module is provided to improve heat dissipation efficiency by forming a PCB made of metal or heat dissipation materials entirely or partially. CONSTITUTION: An LED module(10) comprises one or more LEDs, a PCB(12) and a magnet(17). The LED is mounted on the front of the PCB. The PCB is attached to a lighting device base with the magnet. The entire or rear of PCB is made of metal or heat dissipation materials. The magnet is mounted on the PCB with the magnetic force. One or more heat dissipation grooves are formed on the rear of the PCB. |
