A circuit board coupling structure for a lighting device is provided to increase a lifespan of the light device by protecting the circuit board from the vibration and impact through a fixing stand holder and a holder fixing unit. A circuit board coupling structure for a light device includes a circuit board fixing stand(110), a fixing stand holder(120), and a holder fixing unit(130). A plurality of LED(Light Emitting Diode)s are arranged in a circuit board(100). The circuit board fixing stand fixes the circuit board. Both ends of the circuit board fixing stand are inserted into the fixing stand holder. The fixing stand holder protects the circuit board from the external vibration and the electrical impact. The fixing stand holder is coupled to the inner part of the holder fixing unit. A lamp case(140) is installed between the fixing stand holder and the holder fixing unit. The fixing stand holder and the holder fixing unit are made of the soft insulating material. |
