| 20110141731 | REFLECTION-TYPE LIGHT-EMITTING ASSEMBLY - A reflection-type light-emitting assembly is provided. The reflection-type light-emitting assembly includes a reflector and a plurality of light-emitting elements. The reflector has a concave-shape body and a supporter. The supporter is formed by extending the rim of the concave-shape body toward the center thereof, so as to form a light-emitting opening of the reflector. The light-emitting elements are arranged on the supporter. Light rays emitted by the light-emitting elements fall on a reflecting surface of the reflector and then reflect off the reflecting surface to thereby exit the light-emitting opening. The light rays reflected off the reflecting surface and out the reflector are relatively soft rather than glaringly uncomfortable to the human eyes. | 06-16-2011 |
| 20110051475 | REGULATOR CIRCUITRY FOR REDUCING RIPPLE RESULTED FROM LINE VOLTAGE TRANSMITTING TO SECONDARY SIDE OF POWER TRANSFORMER - The present invention discloses a regular circuitry for reducing ripple resulting from a line voltage transmitting to a secondary side of a power transformer. The regular circuitry electrically connected in parallel with the power transformer includes a ripple sampling circuit, a proportional amplifier circuit, and a reversing amplifier circuit. The ripple sampling circuit selects a sampling ripple from the input port of the power transformer, which is electrically connected in series between a primary side rectification circuit and a secondary side rectification circuit. The proportional amplifier circuit receives the sampling ripple to generate an amplified sampling ripple. The amplified sampling ripple transmits to the reversing amplifier circuit so that a reversed sampling ripple is generated. Thus, the reversed sampling ripple can be input to the output port of the power transformer to superimpose on the signal output from the power transformer to reduce the ripple resulting from the line voltage. | 03-03-2011 |

The foldable solar energy apparatus includes a frame, a first solar energy module, an actuation module, and a power module. A photovoltaic panel is coupled to a first holder of the first solar energy module, and electricity generated by the photovoltaic panel is stored in the power module. The first holder is rotatably coupled to the frame so that the first holder is collapsible via the actuation module, which is disposed at the frame and connected to the first holder. The first holder and the actuation module provide the solar energy apparatus with a foldable function. Thus, the solar energy apparatus can be folded in response to changes in weather conditions, thereby preventing the photovoltaic panel from being damaged by bad weather. | 01-13-2011 |
| 20100328947 | LIGHT-EMITTING DIODE LIGHT SOURCE ASSEMBLY WITH HEAT DISSIPATION BASE - A light-emitting diode (LED) light source assembly with a heat dissipation base is provided. The LED light source assembly includes the heat dissipation base and a light bar. The light bar includes a flexible printed circuit (FPC) board and at least one LED unit which is disposed on the FPC board and electrically connected to the FPC board. The heat dissipation base has two retaining recesses for lodging the side portions of the FPC board, so the FPC board can be thermally conductively connected to the heat dissipation base. Because of the flexibility of the FPC board, it is easy to lodge the FPC board in the heat dissipation base via the retaining recesses. Thus, the cost for arranging the light bar can be economized. | 12-30-2010 |
| 20100320760 | Solar and Wind Power Generator Capable of Tracking Sunlight Automatically - A solar and wind power generator capable of tracking sunlight automatically is provided. The solar and wind power generator includes a base, a revolving column, a generator, a plurality of wind-collecting portions, a plurality of photovoltaic panels, and a secondary cell. The generator is disposed in the base. A wind-collecting element of each wind-collecting portion is coupled to the revolving column by a rotor brake. The revolving column is coupled to the generator. The wind-collecting elements, when driven by wind, rotate the revolving column so as for the generator to generate electric power. The photovoltaic panels are arranged on the wind-collecting elements to absorb sunlight and thereby generate electric power. Electric power generated by the generator and the photovoltaic panels is stored in the secondary cell. Inclination angles of the wind-collecting elements are adjustable by the rotor brakes, allowing the photovoltaic panels to face the sun and track sunlight automatically. | 12-23-2010 |
| 20100302765 | Solar Energy Street Lamp Structure with Adjustable Angle - A solar energy street lamp structure with an adjustable angle is provided. The solar energy street lamp structure includes a lamp holder, a lighting unit, a photovoltaic panel, an electric power storage portion, and an actuation portion. A frame and a holder of the lamp holder are movably coupled by pivot units. The electric power storage portion is placed inside the lamp holder. An actuation unit of the actuation portion is connected between the frame and the holder for adjusting an angle between the frame and the holder such that the lighting unit and the photovoltaic panel, both disposed on the holder, are adjustable synchronously. The photovoltaic panel and the lighting unit are rotatable according to an incident angle of sunlight by adjusting the holder. Thus, the solar energy street lamp structure generates power at enhanced efficiency and can emit light in various directions so as to have wide applicability. | 12-02-2010 |
| 20100302764 | SOLAR ENERGY STREET LAMP STRUCTURE WITH AIR PASSAGEWAY - A solar energy street lamp structure with an air passageway is provided. The solar energy street lamp structure includes a lamp support, a photovoltaic panel, a lighting unit, and a power module. The photovoltaic panel and the lighting unit are coupled with the street lamp, respectively. The power module stores power generated by the photovoltaic panel and provides the stored power to the lighting unit. Moreover, the air passageway is formed between a first body and a second body of the lamp support to enable air circulation. Thus, heat generated by the photovoltaic panel and the lighting unit in operation can be dissipated by air circulating through the air passageway. The solar energy street lamp structure with the air passageway is capable of effective heat dissipation and therefore has an extended service life. | 12-02-2010 |
