Abstract: A sun-tracking solar power generating apparatus includes an upright post (10), a frame (20) located above the upright post, a pivot device (30) pivotally mounted between a top of the upright post and a bottom of the frame, an inclination adjusting device (40) mounted between the upright post and the frame, multiple solar panels (50) mounted on the frame, and a temperature adjustment device (60) mounted on the bottom of the frame. Each of the solar panels includes a self-cleaning reflective layer (53) disposed at an outer face thereof. The self-cleaning reflective layer is made of Teflon material.

Abstract: A solar power generating system includes a solar power generating device (10), a microbubble cleaning device (20) mounted on the solar power generating device, a temperature adjustment device (30) mounted on the solar power generating device, and a controller (40) electrically connected with the solar power generating device, the microbubble cleaning device, and the temperature adjustment device. The microbubble cleaning device produces a liquid containing microbubbles and is controlled by the controller to inject the liquid outward to clean a surface of the solar power generating device. The temperature adjustment device is used to regulate an ambient temperature of the solar power generating device. The controller receives data of power generation from the solar power generating device, and controls on/off operation of the microbubble cleaning device and the temperature adjustment device.

Abstract: A light collector (1), a plurality of densely distributed light collecting protrusions (11) protruding upward from the light collector (1), and a light collecting curved surface (111) is provided on the light collecting protrusions (11) in a curved manner; a plurality of densely distributed Fresnel lenses (12) protruding downward from the light collector (1), and a light emitting curved surface (121) being provided underneath the Fresnel lenses (12) in a curved manner. The light collector (1) of the present invention has low production cost and an effect of increasing light usage rate.

Abstract: A setting/driving circuit is provided for use in conjunction with an IC logic unit, such as a CPU having one or more multi-function pins, to provide two or more sets of data, such as a set of parameter data and a set of control data, via the same multi-function pins to the CPU. The setting/driving circuit includes a tri-state buffer and a parameter setting unit composed of two resistors and a switch, such as a jumper. When the tri-state buffer is disabled, the parameter data set by the switch is transferred to the multi-function pin of the CPU. On the other hand, when the tri-state buffer is enabled, the input data to the input port of the tri-state buffer is transferred to the multi-function pin of the CPU. The tri-state buffer can be integrated within the chip set without having to increase the total number of pins on the chip set so that the layout complexity on the motherboard can be simpler and thus easier to assemble compared to the prior art.
