VERTICAL TYPE LED LIGHTING APPARATUS OF WHICH THE HEAT DISSIPATION IS ENHANCED

摘要

The present invention relates to a vertical LED lighting apparatus (1). A power device support (321) is hung in a space, so that an upper surface and a lower surface may be dissipated at the same time. External air via a central focusing plate (331) spreads sideways at a high speed through a narrow gap between heat dissipation fins (330a) and is externally discharged from a lighting case (200) while a contact area of the external air on the heat dissipation fins (330a) is maximized, so that a cooling effect may be significantly increased by the heat dissipation fins (330a). External air runs against a central portion of a heat dissipation plate (330) through a through hole (331a) of the central focusing plate (331) and is then scattered in all directions, and heat is prevented from being concentrated on a central portion of an LED module (340). In the vicinity of a portion at which the power device support (321) and the heat dissipation plate (330) are provided, the external air runs against a side wall of the lighting case (200) so that the lighting case (200) may be cooled. Thus, even when a person holds the lighting case (200) with a hand, the risk of a burn may be significantly reduced.
