LED LAMP Russian patent published in 2011 - IPC H05B37/00 

FIELD: electricity.

SUBSTANCE: lamp includes inverter made in the form of frequency converter connected to in-series resonant circuit which consists of capacity and inductance of primary winding of resonant high-frequency step-up transformer with core or without core, high-potential output of high-voltage winding of transformer is connected to single-wire line; line includes n in-series connected primary windings of high-frequency step-down transformers (n=1, 2, 3…k); the last of primary windings is connected to natural capacity in the form of insulated conducting body, and secondary winding of each high-frequency step-down transformer is connected to bridge rectifier to the diagonal of bridge of which m light emitting diodes (m=1, 2, 3…r) are connected in series or l light emitting diodes (l=1, 2, 3…p) are connected in parallel. In the other version of LED lamp containing inverter which is made in the form of frequency converter and connected to in-series resonant circuit which consists of capacity and inductance of the first winding of resonant high-frequency step-up transformer with core or without core; high-potential output of high-voltage winding is connected by means of single-wire line to natural capacity in the form of insulated conducting body; to single-wire line there in series connected are n bridge rectifiers (n=1, 2, 3…k); to diagonal of each rectifier there connected in parallel are l light emitting diodes (l=1, 2, 3…p) or in-series m light emitting diodes (m=1, 2, 3…r), and number of m in-series connected light emitting diodes, n bridge rectifiers and l parallel connected light emitting diodes are connected to amplitude of current i_l and voltage U_l of single-wire line with the following ratios U_l > nU_br; U_mn > kU_LED; i_l > i_LED, where U_br - output voltage of bridge rectifier; U_LED - voltage of light emitting diode; i_LED - current of light emitting diode.

EFFECT: reducing energy losses and improving operating reliability of lamp.
