Benefits of technology

This technology helps ensure stable power supply for railroad points when they break down or lose their lights due to damage caused by weather conditions such as rainwater. It can send alarms if there's any problem with one line being used instead of another.

Problems solved by technology

This technical issue addressed in this patented text relates to ensuring safe ignition on railways due to potential damage caused from accidental or intentional inclement welds used along certain lines such as interruptions in electric signals sent through rails. Current solutions involve checking each lamp separately before turning it back on again after being struck down, making sure there'll always be enough spare lamps needed without any issues like short circuits. However, these conventional methods require manual labor and may result in false alarms where emergency signs indicate an illumination condition indicating failure rather than actual failure.

Abstract

The invention discloses an internal secondary filament LED light emitting chip in a railway point type double-filament LED signal lighting device and a cold filament check circuit of a control circuit. The internal secondary filament LED light emitting chip in the railway point type double-filament LED signal lighting device and the cold filament check circuit of the control circuit mainly comprises the internal secondary filament LED light emitting chip and the controlled cold filament check circuit module, the railway point type double-filament LED signal lighting device and a railway signallighting adapter. The spare secondary filament is ensured to be in the normal working state when the main filament of the railway point type double-filament LED signal lighting lamp works normally. If the secondary filament is broken, the alarm signal feedback is sent to the outside immediately so as to ensure the 24h uninterrupted normal and safe operation of the railway signal control and command system.
