Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to an electrooptic lighting device, and more particularly to a reflective electrooptic lighting device. 
       BACKGROUND OF THE INVENTION 
       [0002]    Nowadays, the irradiation of the light emitted from the lighting device used in various places is mostly unidirectional. Therefore, there are limitations for increasing the utilization rate of the light source and for improving the efficacy of the lighting. In order to satisfy the users about the requirement of the intensity of the illumination, it is common to increase the quantity of the installed lighting device. It thus not only increases the cost expense for installation of the light device, but also it is more power consumptive since it requires to use power with a huge power voltage. Moreover, it further causes more unsafe factors which may cause the damage and then may result in the power failure for a considerable wide region. In consideration of efficiency in space, when a more sufficient illumination is required, a larger space is required to allocate a larger lighting device. Therefore, it becomes an important issue regarding how to enhance the efficacy of luminance and to make the lighting device safer and more environment-friendly. 
       SUMMARY OF THE INVENTION 
       [0003]    Thereby, an object of the present invention is to provide a reflective electrooptic lighting device that overcomes the defects existing in the prior arts by increasing the efficacy of luminance so as to save the energy.

A type of reflective electrooptic lighting device could not only require less space for installation, but also can enhance an optoelectronic transform function.
