摘要

The present invention relates to a hybrid LED lighting apparatus based on a PLA plastic complex and a thermal-conductive micro-line having thermal-conductive nano particle powder for improving heat radiation performance and using natural resources. The present invention relates to an LED lighting apparatus having a lamination structure which sequentially includes an LED surface lighting unit (110), a heat sink (120), and an LED surface lighting case (130). The LED surface lighting unit (110) and the LED surface lighting case (130) include a PLA plastic complex having no thermal-conductive nano particle powder. The heat sink (120) includes a PLA plastic complex having thermal-conductive nano particle powder to maximize radiation performance by coming into contact with a thermal conductive line (112) region of the LED surface lighting unit (110). Accordingly, thermal conductivity may be improved on LED lighting requiring a high radiation performance by uniformly distributing the thermal conductive nano particle powder inside the PLA plastic complex which is harmless to a human body and a nature and ensures cost stability. Further, a micro thermal conductive line is formed by selective addition, and an optimized state of the micro thermal conductive line structure is provided in order to improve radiation performance due to a radiation plate formed of a PLA plastic complex having thermal-conductive nano particle powder, and to maximize the radiation performance in an LED surface lighting unit formed of a PLA plastic complex having no thermal-conductive nano particle powder according to the related art.
