LIGHTING APPARATUS FOR MEASURING THE POSITION OF A MOBILE TERMINAL, AND POSITION MEASURING SYSTEM USING SAME
First Claim
1. A lighting apparatus for measuring a position of a mobile terminal by way of visible light communication, the lighting apparatus comprising:
- one or more boundary lighting devices positioned in a boundary part of the lighting apparatus, the boundary lighting devices configured to emit visible light including information for identifying a position of the mobile terminal (identification information);
one or more inner lighting devices positioned in an inner part of the lighting apparatus, the inner lighting devices configured to emit visible light including the identification information; and
one or more boundary concentrator units implemented respectively on at least some of the one or more boundary lighting devices, the boundary concentrator units configured to concentrate visible light emitted from the at least some boundary lighting devices.
