Orbital Phase

RSCVn stars are fully detached binary stars which show intrinsic small amplitude (up to 0.3 amplitude peak-to-peak) light variations, as well as, in most of the known cases, eclipses. The spectra are F to G, IV to V for the hotter component and usually KOIV for the cooler. They are also characterised by abnormally strong H and K emission from the cooler star, or, occasionally, from both components. The orbital and light curve periods are in the range 1 day to 2 weeks. An interesting feature is the migration of the light variations to earlier orbital phase, as the light variation period is shorter than the orbital period by a few parts in 10+4to a few parts in 10+3.

Two Stages

A new concept of the architecture of hybrid lighting systems for installations of combined lighting is considered. The cascade principle of constructing the optical path of such complexes is described, in which the design contains two stages of the cascade: the upper and lower stages. The upper (input) structure is made on the basis of the corresponding modification of the hollow tube “Solatube®” (daylight), and the lower one, based on the “Solatube®” fibre of a larger diameter, is combined with LED artificial light block and is designed to transmit mixed light (daylight and artificial light). The results of studies on the efficiency of light transmission made it possible to optimize the solution of the new modification of the hybrid lighting complex “Solar LED”, lower stage of the cascade, and to develop the nomenclature of the production line “S”. The description of the first experience of using this complex in the pilot combined illumination system of the “meeting room” in the shopping centre “IKEA Belaya Dacha” headquarters is given. A completely autonomous power supply system for a lighting installation based on solar panels has been implemented.
