Abstract:
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.
Abstract:
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.

A foldable solar energy apparatus is provided. 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.

The present invention discloses a solar energy lamp having a fiber display. The solar energy lamp includes a lamp support, a photovoltaic panel, a lighting module, a fiber display module and a power module. The photovoltaic panel is disposed on the lamp support and the lighting module is disposed on a housing of the lamp support for lighting. The fiber display module is located at an appropriate location of a pole set of the lamp support for watching. Besides, the power module can save the electrical power generated by the photovoltaic panel and the power module also can control the lighting module and the fiber display module to turn on or turn off. Because of the usage of the photovoltaic panel, the solar energy can be the power source of the lighting module and the fiber display module. Thus, it can achieve the purpose of saving energy.
Abstract:
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.
Abstract:
The present invention discloses a lamp structure for illuminating and displaying. The lamp structure includes a lamp support, an elevator module, a lighting-displaying module and a control module. The elevator module is combined with a rod of the lamp support. The lighting-displaying module is combined with the elevator module to elevate or lower with the movement of the elevator module and the control module is used to control the elevator module. The lighting-displaying module elevating with the elevator module to a first location is switched to an illumination mode for illuminating, while the lighting-displaying module lowering with the elevator module to a second location is switched to a display mode for displaying. The elevator module is controlled by the control module to elevate or lower so that the lighting-displaying module is at an appropriate location for illuminating or displaying to extend the application field of the lamp structure.
