Sunlight collector module and a hybrid illumination system having the same

A hybrid illumination system, in cooperated with a solar photovoltaic module, comprising:

• a sunlight collector module including a base, a first reflective element, a second reflective element, a light-guide element, and a beam splitting element, wherein the first reflective element disposed on the base;
• the second reflective element disposed on a side, which is opposite to the base, of the first reflective element;
• while a reflection surface of the second reflective element is opposing to a reflection surface of the first reflective element;
• the light-guide element disposed on a side, which is opposite to the second reflective element, of the first reflective element;
• the a beam splitting element disposed between the first reflective element and the light-guide element;
• a light box including a surrounding wall, a light sensing unit, plural light emitting units and a light output surface, wherein the surrounding wall and the light output surface enclose the light sensing unit and the plural light emitting units therein;
• the plural light emitting units are disposed on the surrounding wall and emitting light to the interior space of the light box;
• and
• a control module coupled with the light sensing unit and the plural light emitting units;
• wherein a sunlight from the sun is sequentially reflected by the reflection surface of the first reflective element and the reflection surface of the second reflective element, then, passed through the beam splitting element and arrived the light-guide element;
• the beam splitting element reflects portion of the sunlight passed through, having the wavelength in a pre-determined wavelength range, to the solar photovoltaic module;
• the light-guide elements guides the light entered therein to the light box;
• the light sensing unit senses the illuminance of the interior space of the light box and obtains an illuminance value;
• the control module controls the light emitting of the plural light emitting units based on the illuminance value, for maintaining the illuminance value of the light output from the light output surface, in a pre-determined range.
