Abstract: An actuator is disclosed. The actuator, which includes a base; a shaft, of which one end is rotatably joined to the base; a case secured to the other end of the shaft; a magnet mounted on one side of the case; a coil secured to the base to face the magnet; a mirror joined to the case and positioned on a light path to reflect light; and a guide having a guide hole that is capable of controlling the rotation angle of the mirror, not only has a small volume to be applicable to a mobile terminal, but also allows easy control of the mirror.

Abstract: A fan having a dust-proof apparatus includes: a casing having a passage; a rotation driving unit installed inside the casing; a plurality of blades positioned in the passage and coupled to a rotational shaft of the rotation driving unit so as to be rotated; and a dust-proof member installed at an entrance of the passage to cover the entrance of the passage, and integrally coupled to the blades so as to be rotated together with the blades. Since insects or big dusts can be prevented from being introduced according to an air flowing generated as the blades are rotated, and the coupling state between parts is firm. In addition, since the eccentricity is minimized, the parts are not damaged, and as a noise generation is restrained, so that reliability can be heightened.

Abstract: An electrodeless lighting apparatus using microwave comprises: a waveguide for transmitting microwave generated in a magnetron; a mesh screen coupled to an outlet portion of the waveguide for blocking a leakage of the microwave and passing light; a bulb located in the mesh screen for emitting light by generating plasma by the microwave; and a globe installed on outer area of the mesh screen so that the light generated in the bulb can be radiated to omnidirection, that is, the globe is installed around the bulb instead of a reflector and a light guide which are used in the conventional art, and thereby, a structure of the lighting apparatus can be made simply and an omnidirectional lighting can be performed.

Abstract: In a lighting apparatus using microwave energy including a magnetron for generating microwave energy, a bulb for generating lights by the microwave energy, a wave guide for connecting the magnetron and the bulb and transmitting the microwave energy generated in the magnetron to the bulb and a casing housing the magnetron and the wave guide and combining with the bulb, a cooling system of a lighting apparatus using microwave energy comprises a heat exchanger installed to the exterior of a magnetron and having a coolant path, a radiating unit installed to the exterior of a casing and radiating heat of the coolant heated while passing the path of the heat exchanger, and a flow generating means installed between an outlet of the radiating unit and an inlet of the heat exchanger in order to make the coolant circulate the heat exchanger and the radiating unit.
