A new concept of integrated systems, named “IoT station”, using laser scan technology with visible laser diodes (LDs) common to smart lighting and LiDAR is proposed. It is applicable not only for smart lighting but also for image projection, power supply, and optical communications. As a fundamental verification of this system, a LiDAR using a LD emitting at red wavelength with two-axis scanning mechanism is fabricated for the first time. 3D image caption with detectable distance up to 10 m is achieved by the visible LiDAR. Spot lighting, projections, space signal transmissions and wireless power supply using light beam scanning are also verified as multi-purpose extended system. Additionally, spot lighting of which illumination area is controlled by visible LiDAR, has been successfully demonstrated.
