FIELD: electricity.
SUBSTANCE: invention is attributed to electrical industry specifically to power-saving lamp design and can be used for general purpose filament lamps. Lamp with protection against unauthorised unscrewing contains light-emitting diode assembly or discharge tube or bulb with emission source located in it, side and central conductors connected with emission source and serving to supply current to emission source, and base consisting of outer and inner parts which are made capable to rotate relative to each other. In this structure light-emitting diode assembly or discharge tube, or bulb is hard-mounted on inner part of base, inner and outer parts of base are made capable to turn relative to each other by angle α, and this rotation performed when the lamp is unscrewed from its holder causes side conductor to be destroyed.
EFFECT: impossibility of lamp unscrewing from its holder without its breaking.
