Furthermore, since a moving passage formed by a capillary protrusion enables smooth circulation of a cooling medium so as to uniformly distribute the cooling medium to the entire filling space, heat generated from an LED module is uniformly distributed to the entire part of the outer case, thereby improving a radiation effect. Furthermore, since a radiation fin increases an area coming in contact with outside air, a radiation effect is capable of being improved.
