The TKH Inset Intermediate Holding Position Light Type IHP is a high-performance, LED-based airfield ground lighting solution designed to provide clear and reliable visual guidance at runway and taxiway holding positions. Engineered for durability, efficiency, and compliance with international aviation standards, the IHP light plays a critical role in maintaining ground traffic safety and operational efficiency in all weather conditions.
The fixture is available in an 8-inch standard outer diameter, with an optional 12-inch version for specific infrastructure needs. Its low-profile design measures just 6.35 mm above the surface, with a depth of 35 mm below the flange, ensuring smooth integration into paved surfaces and minimal disruption to aircraft or vehicle movement. The precision light outlet, sized at 40 mm by 6 mm, delivers bright, focused illumination that is omnidirectional and visible from critical angles. The light meets stringent ingress protection standards with an IP68 rating, providing complete protection against dust and water, making it suitable for continuous outdoor exposure in harsh airfield environments.
The IHP light offers a remarkably long operational life, with an expected system lifespan of over 20 years and an LED lamp life reaching up to 50,000 hours. It is fully compliant with chromaticity and color output specifications outlined in ICAO Annex 14, Volume 1, and FAA AC 150/5345-46E, ensuring its suitability for both international and domestic airports.
Designed for integration into a 6.6-amp series circuit, the IHP supports full dimming capabilities from 0 to 100%. Power consumption is 11 watts per side at full intensity, with voltage ranging from 0.9 V (at 0.1% output) to 1.9 V (at 100% output). It maintains an excellent power factor greater than 95% at nominal current, contributing to overall system efficiency. Engineered to operate in extreme environments, the fixture remains fully functional across a broad ambient temperature range of -55°C (-67°F) to +85°C (+185°F), ensuring reliability in polar, temperate, and tropical climates.
For enhanced functionality, the IHP includes an internal serial interface for diagnostics and parameterization, allowing operators to monitor performance and configure settings remotely. Optional features enhance the system's adaptability, including a fail/open function for added operational safety and a de-icing kit for cold weather environments, which adds a minimum of 14 watts of power consumption while active. A sapphire-coated prism is also available for increased durability and optical clarity in high-wear locations.
The IHP light can also be equipped with integrated single lamp control when used with CEDD® (Contactless Energy and Data Distribution) technology. CEDD® offers a smart, safe, and sustainable approach to airfield lighting by combining power and data transmission through a single inductive cable. This technology enables airfield lights to receive energy and data without physical electrical connections, making installation, replacement, and maintenance significantly safer and faster while minimizing disruption to airfield operations.
In summary, the TKH Inset Intermediate Holding Position Light Type IHP delivers a robust, efficient, and technologically advanced lighting solution for critical ground traffic control zones. Its durable construction, compliance with global standards, and compatibility with cutting-edge CEDD® systems make it a future-ready component for any airfield lighting infrastructure.
