OCEM Airfield Technology

The LIRE is a 12-inch diameter inset LED fixture that delineates the lateral boundaries of a runway, replacing traditional series-wired halogen units while drawing a fraction of the electrical load.

The LIRD is a unidirectional 8-inch inset LED fixture that forms the touchdown zone lighting (TDZL) array on precision-approach runways.

The LITG is a 12-inch inset LED runway guard light (RGL), the pavement-level component of the runway-entry warning system at taxiway-to-runway intersections.

The LERA is an elevated LED light that serves four distinct airfield positions from a single product platform: approach lighting, threshold and threshold wing-bar lighting, runway-end lighting, and stop-bar lighting.

The LEFL (elevated) and LIFL (inset) are LED flashing lights serving three distinct visual-aid roles: sequential flashing lights (SFL) in approach systems where a strobing 'running rabbit' effect guides pilots down the centreline; Runway End Identification Lights (REIL) that make the runway threshold conspicuous from the air at non-precision aerodromes; and Circling Guidance Lights (CGL) that assist pilots executing visual circling manoeuvres around the aerodrome at night.

The LITC is a multi-role inset LED fixture that consolidates three distinct surface-movement lighting functions — taxiway centreline guidance (green), runway-entry stop bar (red), and intermediate holding position lights — into a single product family available in both 8-inch and 12-inch diameters.

The LEMIRL is OCEM's elevated medium-intensity runway light (MIRL), designed as the above-ground complement to inset fixtures for runways where pavement cutting is impractical or where elevated fittings are operationally preferred.

The LERE is an elevated LED fixture covering the two most numerous elevated-light positions on a runway: edge lights (white in the landing direction, yellow in the last 600 m) and threshold/end lights (green threshold-facing, red runway-end-facing).

The LIRC is an 8-inch inset LED light that serves two distinct safety-critical roles: primary runway centreline lighting for precision-approach operations, and Rapid Exit Taxiway Indicator Light (RETIL) guidance that signals pilots approaching high-speed turn-off points.

The LITE is an omnidirectional inset LED taxiway edge light, providing the blue lateral delineation of taxiway edges at night and in low-visibility conditions.

The LIRA is a unidirectional 12-inch inset LED light designed for the approach lighting system (ALS) inset positions: centreline lights, crossbar lights, and side-row barrette lights in the touchdown zone of approach systems such as ALSF-2, MALSR, and ICAO CAT II/III approach configurations.

The LIRT is a 12-inch inset LED light that covers two spatially distinct but functionally related roles: the runway threshold lights that mark the beginning of the landing area, and the threshold wing-bar lights that extend the green threshold indication laterally beyond the runway edge to give pilots a wider field-of-view reference on final approach, particularly in fog or when breaking out of cloud on a wide-body approach.

The OCEM LED PAPI is a Precision Approach Path Indicator system providing pilots with a colour-coded visual glide slope reference on final approach.
