Automatic sunlight tracker of 3 dimensional movement reflective mirror sunlighting device

摘要

The present invention relates to a solar tracking device comprising: a distance adjusting unit which automatically adjusts the distance between a condenser lens and a position tracking sensor based on the luminosity of sunlight; and an infrared blocking member which prevents temperature inside a housing from rising above a fixed temperature. The solar tracking device can adjust the housing in virtual X, Y, and Z-axial directions. Provided is the solar tracking device with the distance adjusting unit comprising: the cylindrical housing; the condenser lens which is positioned in an upper opening of the housing; the position tracking sensor which is positioned on a lower opening of the housing and is made of plural photo cells to track the position of the sun based on light incident through the condenser lens; and the distance adjusting unit which adjusts the distance between the condenser lens and the position tracking sensor. The distance adjusting unit comprises: a vertical movable pin of which one end is coupled and fixed with a board in which the position tracking sensor is mounted; a motor which vertically moves the vertical movable pin; a luminosity sensor which senses the luminosity of incident sunlight; a controller which drives the motor based on the luminosity transmitted from the luminosity sensor; a mounting base which is fixed and installed inside the housing and wherein the motor is mounted; and a guide rod which is fixed and coupled with the base, inserted into a guide hole drilled on the board, and guides the vertical movement of the board without tilting the board.
