| 20090067152 | ROTATING LAMP - The inventive rotating lamp comprises a substrate, a translucent globe mounted on the substrate, a shaft portion set in the substrate, a rotatable member rotatably supported by the shaft portion, a main reflecting mirror, arranged on the upper surface of the rotatable member, having a light reflecting surface constituted of a paraboloid, a light-emitting diode and a drive portion rotating/driving the rotatable member, and the optical axis of the light-emitting diode and the reflecting surface of the main reflecting mirror intersect with each other. Thus, a rotating lamp employing a light-emitting diode capable of delivering light emitted from the rotating lamp to a distance place by improving reflection efficiency can be obtained. | 03-12-2009 |
| 20090091914 | ROTATING LAMP - A rotating lamp comprises a translucent globe, a shaft portion, arranged in the globe, made of a material containing metal, an LED device provided on the shaft portion, a rotatable support member rotatably set along the outer peripheral direction of the shaft portion, a reflecting mirror supported by the rotatable support member for reflecting light received from the LED device, a driving portion rotating/driving the rotatable support member and a heat radiating portion provided on the shaft portion. Thus, heat generated in LED devices can be discharged and a problem resulting from heat can be solved. | 04-09-2009 |

| 20090148114 | THREE-DIMENSIONAL PHOTONIC CRYSTAL AND MANUFACTURING METHOD THEREOF - A three-dimensional photonic crystal includes a structure that includes first, second, third, and fourth layers in this order. The structure of each layer includes a flat surface as one end surface, and first, second, and third structural portions. The first structural portion has a first width along the flat surface and a first height from the flat surface. The second structural portion has a second width larger than the first width and a second height larger than the first height. The third structural portion has a width and a height that continuously or stepwise change in the extending direction of the structure. The flat surface at the structural portion of one of two adjacent layers in the first layer to the fourth layer contacts a surface opposite to the flat surface at the second structural portion of the other of the two adjacent layers. | 06-11-2009 |
| 20090201960 | THREE-DIMENSIONAL PHOTONIC CRYSTAL LIGHT EMITTING DEVICE - The three-dimensional photonic crystal light emitting device includes a three-dimensional photonic crystal, and a defect forming a resonator in the three-dimensional photonic crystal. In the three-dimensional photonic crystal, an N-cladding layer formed of an N-type semiconductor, an active layer disposed inside the resonator, a P-cladding layer formed of a P-type semiconductor, a tunnel junction layer, and a first N-conductive layer formed of a first N-type conductor are arranged in this order. Electric conductivity of the first N-type conductor is higher than that of the P-type semiconductor. The light emitting device achieves high carrier injection efficiency and a high optical confinement effect. | 08-13-2009 |

| 20090092368 | METHOD FOR FABRICATING THREE-DIMENSIONAL PHOTONIC CRYSTAL - At least one exemplary embodiment is directed to a method for fabricating a three-dimensional photonic crystal. In the method for fabricating the three-dimensional photonic crystal, a plurality of layers can be defined as one unit, and the total thickness of the one unit can be controlled such that an average layer-thickness of the plurality of layers in the one unit is about equal to the ideal layer-thickness so that a photonic band-gap occurs in a desired wavelength region. | 04-09-2009 |
