The casing is made as a socket; the front open end face of the socket is closed by a cover with a central opening and the back end face is fitted by an opening as well. The lamp is fixed on a plate with a microchip and an output wire; the plate is set inside the casing with the help of centering insertions. The output wire is laid into the central opening of the back end face and equipped by a plug with flat contacts and the lamp is a glow discharge lamp. The cross section of both the casing and the cover can be of round or polyhedral shape. ^ EFFECT: producing a light source which can be used in the whole set of physical laboratory works ie meant not only for optical phenomena but also for other sections, is easy to produce and use, reliable and demonstrable. ^ 2 cl, 2 dwg |
