METHOD OF CYLINDRICAL CARD WITH LIGHT-EMITTING DIODES PRODUCTION AND LIGHT-EMITTING LAMP Russian patent published in 2009 - IPC H01L25/75 

FIELD: electrical engineering.

SUBSTANCE: invention relates to LED-based semi-conducting instruments production and may be used for manufacturing LED lamps in obstruction lights and signal lamps for ground lights, towers, high and long buildings and for light lamps and illumination. Method of cylindrical card with LED production includes the following steps: power unit and light-emitting diodes are placed on rectangular card work pieces. Besides, the power unit elements are placed on the end part of the card work piece. After that, it is bent at an angle to the card plane along the line parallel to the card work piece height. The next step includes bending of the card work piece around the bent end part until the hollow cylinder is formed, i.e. hollow cylindrical card with light emitting diodes being situated on its external surface and power unit elements being situated inside.

EFFECT: increase of manufacturability, reduce of assembling labour intensity and improvement of vibration stability of structure.
