2. Daylighting (architecture) - Wikipedia

   en.wikipedia.org/wiki/Daylighting_(architecture)

   Oak Ridge National Laboratory (ORNL) has developed a new alternative to skylights called hybrid solar lighting. This design uses a roof-mounted light collector, large-diameter optical fiber, and modified efficient fluorescent lighting fixtures that have transparent rods connected to the optical fiber cables. Essentially no electricity is needed ...

   Light can be used to transmit data and analog signals. For example, lighting white LEDs can be used in systems assisting people to navigate in closed spaces while searching necessary rooms or objects. [100] Assistive listening devices in many theaters and similar spaces use arrays of infrared LEDs to send sound to listeners' receivers.
