Reconfigurable intelligent surfaces (RIS) supply high-speed and in-depth coverage wireless networks for visible light communication (VLC) systems, improving the system adaptability to mobile scenarios. But the angle-related efficiency loss caused by the diffraction effect of RIS as well as the angular response of the lens-enhanced optical receiver severely affects the practical performance of the RIS-assisted VLC system, which have not draw the attention of researchers. By the influences of these adverse properties, the beam angle configuration method should be further explored. In this paper, a RIS-assisted optical receiver model that jointly considering the angle-related characteristics of both the RIS reflector and the receiver is proposed. Based on the model, the receiver property is characterized, and the beam angle optimization to achieve the maximum optical power is presented. The results of simulations verify the validity of the obtained optimal reflected angle, and test the practical detecting range of the optimally configured RIS-assisted receiver.
