Sunlight lighting reflective mirror sun following device

Abstract

A sunlight lighting reflective mirror sun following device comprises two sunlight localization sensors, wherein one of the sensors is used for judging the sun direction on a vertical face, and the other sensor is used for judging the sun direction on a horizontal face. Due to the fact that any sunlight direction in space can be divided into two directions in the vertical face and the horizontal face, the two sunlight localization sensors can judge sunlight in any direction, a controller collects signals generated by the sunlight localization sensors and then controls and drives motors to rotate, a first motor drives a mirror frame to rotate along a horizontal shaft, a second motor drives a reflective mirror to rotate along a vertical shaft, and therefore the reflective mirror can freely rotate in a 360-degree range, and sunlight at any direction can be reflected by the reflective mirror to vertically and downwards irradiate a courtyard through automatic adjustment of the angles of the reflective mirror. The device is reasonable in design, simple in structure, energy-saving, environmental friendly, simple and convenient to operate, and capable of effectively solving the lighting problem of windows in a high-rise building courtyard.

Description

technical field [0001] The invention relates to an illuminating device, in particular to a sunlight illuminating reflector and sun tracking device. Background technique [0002] With the acceleration of urban construction, high-rise buildings have sprung up like mushrooms after rain. Super high-rise buildings have more floors and occupy a larger area than ordinary buildings, resulting in extremely poor lighting in some rooms. In order to solve this problem, patios are designed on the top of many high-rise office buildings, luxury commercial buildings and other buildings for lighting and ventilation. However, only relying on the patio is not enough to allow the internal rooms of the building to be illuminated at any time during the day. As the sun rises and sets in the west, some rooms will not be exposed to natural light at a certain period of time, so they rely on indoor lighting devices for lighting, which causes energy consumption. massive consumption. If there is a li...

Problems solved by technology

However, only relying on the patio is not enough to allow the interior rooms of the building to be illuminated at any time during the day. As the sun rises and sets in the west, some rooms will not be exposed to natural light at a certain period of time, so they rely on indoor lighting devices for lighting, which causes energy consumption. massive consumption of

If there is a lighting device that can automatically irradiate sunlight vertically downwards from the top of a high-rise building into the patio at any time, it can solve the lighting problem of the windows in the patio of the above-mentioned high-rise building.
