1. A Light Emitting Diode (LED) module comprising:
- a lighting unit including an LED chip;
a module body supporting the lighting unit at a leading end and extending from the leading end to a rear end for a predetermined length, the leading end being structured to guide light from the lighting unit in an upward direction, the module body being made of a high thermal conductivity material and having a through hole extending through the length of the modular body;
a connector sealingly coupled to the rear end of the module body, the connector having a conductor inserted into and extending through the through hole in the module body for supplying external voltage to the lighting unit; and
a transparent member coupled with the leading end of the module body to seal and protect the lighting unit and a portion of the conductor exposed from the leading end of the module body from an external environment.

Abstract
The present invention relates to an LED module for automobile headlights. The LED module comprises a water proof structure together with a heat radiating structure in order to prevent the permeation of external moisture while efficiently radiating heat to the outside. The LED module may be combined with a lamp housing and a radiator to constitute an automobile headlight.
