Automotive LED headlamp modules are provided. An automotive LED headlamp module according to an embodiment of the present invention includes a metal plate for supporting an LED lamp; And a second region formed of heat-dissipating plastic and including at least one protrusion for improving a specific surface area in a first region, which is a receiving portion for accommodating a part or all of the metal plate, and an opposite region corresponding to the first region. It is implemented including; a heat dissipation case comprising a. Accordingly, by including a metal plate and including a heat dissipation case made of heat-dissipating plastic, excellent heat dissipation performance can be expressed by not only excellent thermal conductivity but also thermal radiation. In addition, since the metal plate is made of light metal or the heat radiation case includes a protrusion made of heat-radiating plastic rather than a metal pin or a metal plate, excellent heat dissipation performance is exhibited and there is a light effect. In addition, as it contains a heat-radiating filler of an appropriate particle diameter and an appropriate content, a metal plate is inserted-molded and accommodated in a heat-radiating case, and includes a heat-dissipating plastic and a hetero-injected joint, it has excellent bonding properties between parts, especially for bonding between dissimilar materials. Since the bonding strength between parts is very excellent, the effect of excellent durability can be expressed.
