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.
Claims21
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.
