LED MODULE WITH PASSIVE LED Russian patent published in 2014 - IPC F21S4/00 H01L31/00 H01L33/00 

FIELD: electricity.

SUBSTANCE: invention relates to a LED module. A module consists of several LEDs installed on a printed circuit board with the LEDs having respectively the so-called layup with a lens by which the respective LED extends beyond the printed circuit board plane, the LEDs are connected respectively with an element for the input of optical radiation of a light guide body and the respective luminous flux of matched LEDs is emitted outside from the LED module by means of respectively matched element for luminous flux input. At least one passive LED which can be activated if one of LEDs fails is provided on the printed circuit board for LEDs in order to achieve homogeneous appearance. The luminous flux emitted by these passive LEDs enters the luminous flux input element of the respective LED and is emitted outside by the luminous flux input element.

EFFECT: development of a LED module consisting of several LEDs set on a printed circuit board, failure of some LEDs is not seen from outside due to the "input" of the luminous flux, emitted by the passive LED, into the luminous flux input element of the failed LED.
