摘要： Disclosed is a fan module used in electronic equipment and the like. The fan module of the present invention includes a dust-collecting part which has an air’-suction port and an air-discharge port, and which has a rotational region forming a passage linking the air-suction port to the air-discharge port and has a dust-collection box for collecting dust and detritus rotating in the rotational region; and a fan which is joined to one side of the dust-collecting part and makes air flow into the rotational region. The present invention can use centrifugal force to effectively remove various forms of dust and detritus contained in the air which flows into the casings of electronic equipment, household appliances and the like due to the action of a fan. Further, since a filter is not used, there is the advantage that the cooling efficiency is not reduced by the dust collection as the smooth flow of the air being sucked in is not disturbed. Further, from the long-term point of view, the thermal efficiency of electronic equipment and the like can be substantially improved as the amount of dust and detritus accumulated inside electronic equipment is minimized.

摘要： The present invention relates to an LED illumination apparatus and a manufacturing method thereof. The LED illumination apparatus according to one embodiment of the present invention comprises: a body in which a heat sink including a plurality of heat radiation fins is formed in a first area of a bottom surface portion thereof and in which a light source loading area is formed in a second area different from the first area in the bottom surface portion; a substrate loaded on the light source loading area of the body; and an LED light source module provided on the substrate. According to the present invention, since the heat sink is formed in the bottom surface portion of the body, the reduction of heat radiation efficiency in the LED illumination apparatus due to dust or excrement of birds and the like can be minimized. In addition, since the body is manufactured by extrusion molding, the manufacturing cost of the LED illumination apparatus can be remarkably reduced in comparison with prior die casting. In addition, since the length of the body can be adjusted arbitrarily, the present invention can be designed in various shapes according to a desired heat radiation area.
