摘要： Disclosed are an optical signal concentrator and an optical receiver for wireless optical communication. The concentrator includes a diffusion sheet and a light guide plate positioned below the diffusion sheet for guiding diffused optical signals perpendicularly to the incident direction the diffused optical signals, the light guide plate being formed with at least one concentric circle pattern facing the diffusion sheet. The receiver includes an optical signal concentrator including a diffusion sheet, a light guide plate positioned below the diffusion sheet for guiding the optical signals perpendicularly to the incident direction the diffused optical signals, one or more optical detectors for detecting light projected to the side of the light guide plate, and a reflection plate for reflecting light incident to the light guide plate.

摘要： Disclosed is a color lamp driving apparatus for generating illumination light of various colors by using a plurality of Red (R), Green (R), and Blue (B) lamps together with each other, having a color controller for generating a color control signal, which indicates driving time rates of R, G, and B lamp arrays, according to color information of required illumination light, and a lamp driving module for outputting a driving signal for driving each of R, G, and B lamp arrays according to the color control signal output from the color controller. The driving signal is set to apply driving times for the R, G, and B lamp arrays based on one among a start time point, a middle time point, and an end time point of each corresponding period ΔT within one light-emitting period T.
