Title:
HEATSINK FOR LIGHT
Document Type and Number:
WIPO Patent Application WO/2015/102422
Kind Code:
A1
Abstract:
The present invention relates to a light heatsink for cooling a lighting device by radiating heat generated from a light. The light heatsink, according to one embodiment of the present invention, is a heatsink for a light for radiating heat generated from the light, comprising: an outer case combined with the light; an inner case which is accommodated inside the outer case and is spaced therefrom such that a filling space is formed between the inner case and the outer case; and a cooling medium for cooling the light by being vaporized by the heat generated from the light in a part of the outer case combined with the light. Thus, the radiating device for a light improves a vaporizing speed of a cooling medium through a medium dispersing channel so as to prevent heat generated from an LED module from locally increasing in an outer case, such that a radiation effect is capable of being improved. 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.
