GENERAL ELECTRIC INCANDESCENT LAMP WITH DOUBLE LUMINOUS ELEMENT Russian patent published in 2015 - IPC H01K9/04 

FIELD: electricity.

SUBSTANCE: invention relates to lighting engineering. Technical result is achieved in that the incandescent lamp contains a glass bulb, in which I series in same plane on two side and on one common electrode the two luminous elements are secured. At that one of the side electrodes is connected with metal part of the base, and second end of the second side electrode is connected with the mushroom-shaped contact. The second end of the common electrode goes out eccentrically to the insulation part of the base with possibility of its contact with the second ends of the first and second side electrodes using the shorting contact. The technical result is achieved in that the electric contacts, to which the electrode ends are connected, are made as poles with holes, and the shorting element is made in form of pin, at that poles and pin are made from the same material.

EFFECT: increased reliability, operability and durability of the lamp by assurance of the possibility of the lamp operation with one luminous element or with two luminous elements.
