High intensity LEDs to mimic the tube

Oxley Developments has secured a production order to supply LED displays for use in rail side electronics equipment on the London Underground.

Oxley Developments has secured a production order to supply LED displays for use in rail side electronics equipment on the London Underground.

The high intensity LEDs have been customised for use in illuminated control boxes known as mimic panels which identify the schematic outline of the underground railway tracks.

The LEDs will be supplied to a contractor of the London Underground who builds and maintains the railway tracks.

The order follows an initial requirement for prototypes which successfully passed a qualification programme and have now been granted approved for manufacture into the panels.

The single chip displays are a customised variant from the Oxley OXL/CLH mid-range of LEDs.

They include many features of robust, quality, high specification military devices but these are lower in price rendering them cost effective for design into industrial applications.

This variant of LED has three options of colour indication in one lamp, which is superior to other LEDs on the market as it reduces the number of LEDs the customer requires from three to one.

Sealed to IP66 the LEDs have an operating temperature range of 40 to +100C and in addition to standard power of 12, 24 and 28V, customised options are also available.

The LEDs are easily adaptable to specific applications and Oxley provide mounting sleeve options varying from 10 to 22mm in diameter, a choice of colours combinations and flying leads if required.
