FIELD: lighting.
SUBSTANCE: LED lamp comprises a LED unit (740), network link, the first and second switching devices (710, 720) (eg, first and second relays) and a control unit (730). The control unit (730) detects the ignition voltage in the power line. In response to the detection of the ignition voltage in the power line, the control unit (730) sets the first and second switching devices (710, 720) in the conduction state so that the light module (740) is connected to the power source.
EFFECT: increased security when installing LED lamp bulb (700) in reinforcement, engineered for fluorescent lamps.
