Abstract: A solar tracking device for solar panel includes a barrel body, a light transmitting unit, a projecting unit, a photosensor unit, and a lens. The light transmitting unit is disposed at a first end of the barrel body oriented toward the sun. The light transmitting unit has a light-transmittable crossing point provided at a center thereof. The projecting unit is an opaque member arranged between the first end and a second end of the barrel body. The photosensor unit is arranged to one side of the projecting unit, so that the projecting unit is located between the light transmitting unit and the photosensor unit. The photosensor unit has a locating center preset at a center of the projecting unit. The lens is arranged between the projecting unit and the photosensor unit. The barrel body is a telescopic barrel enabling the solar tracking device to switch between different operating angle modes.

Abstract: A photoelectric lens module is utilized to focus a light source. A fabrication method comprises steps of providing a first substrate; positioning a plurality of gap units on the first substrate, and forming a plurality of gap regions amongst the gap units on the first substrate; providing a second substrate comprising a plurality of photoelectric lens units, in which the positions of the photoelectric lens units are corresponding to the locations of the gap regions; and filling a transparent rubber in the gap regions in such that the first substrate and the second substrate are adhered closely.

Abstract: A light emitting diode lens structure includes a lens having an upper section and a lower section. The lower section is provided with a light emitting diode accommodation part. The upper section is coated with a specular reflection layer to form a reflecting surface facing the light emitting diode accommodation part. An illumination apparatus with the light emitting diode lens structure includes a lampshade, a locking module, an electrode module, and a light emitting diode. The lampshade has a reflecting light surface and an aperture. The locking module is coupled on the lampshade and has a through hole corresponding to the aperture. The electrode module is coupled on the locking module and corresponds to the through hole. This design provides a significant reduction in glare to reduce eyestrain.

Abstract: A solar power generating device includes a solid cylindrical conductive body partially surround by a hollow cylindrical conducting layer with an insulating layer located between them, and a solar energy converter located at an end of the conductive body with two electrodes separately electrically connected to the conducting layer and the conductive body, so that the solar power generating device is configured as a plug-in module that could be very easily mounted to and dismounted from a circuit board.

Abstract: A solar power generating device includes a first conductive body, a second conductive body and an insulating body sequentially disposed on the first conductive body, and a solar energy converting unit. The first conductive body has a conducting post upward projected from a hollow sleeve portion of the insulating body and a through opening of the second conductive body, so that a conducting section at a top of the conducting post is exposed at the insulating sleeve portion. The solar energy converting unit is mounted on the conducting section of the first conductive body and in electric contact with the second conductive body. With these arrangements, the solar power generating device may be mounted on a circuit board without the need of distinguishing the polarities of electrodes, and can therefore be easily mounted to and dismounted from the circuit board and be conveniently replaced when necessary.
