Highway Crossing Equipment Ansaldo STS USA HC-120B Flashing Light Units ASTS USA s HC-120B Flashing Lights meet or exceed industry standards for motorist visibility at highway crossings in all types of environments and installations, and are designed for maximum ease of maintenance. At the heart of the HC-120B assembly is an LED-based light unit that is simpler in design, longer lasting and consumes much less power than comparable incandescent lamp units. The HC-120B is available in a variety of multi-light assembly configurations, as well as individual light unit designs. Included is a retrofit version that allows replacement of existing incandescent light units with the new LED technology. General Description Flashing Light Assemblies HC-120B Flashing Light assemblies utilize all-aluminum brackets and junction box crossarms, and are provided with two light units for 1-way configurations, or four light units for 2-way configurations. Selected models of the 2-way version are available with extension arms for additional clearance on the highway crossing mast. Clear access for wiring is provided through a threaded crossarm mounting fitting. Threaded elbows permit independent horizontal (azimuth) and vertical (range) adjustment of each signal. Standard AREMA terminals serve as quick connect/disconnect points. Light unit options include the new LED or traditional incandescent models; these can be outfitted with a variety of hoods and backgrounds made of high durability plastic or aluminum. HC-120B assemblies can be mounted on 4 or 5 (10.2 cm or 12.7 cm) masts, and selected models are designed for use with ASTS USA s Model 95 Gate Crossing Mechanism. Flashing Light Units HC-120B Flashing Light units combine the best features of existing housing design with LED light source technology, and are compliant with both AREMA and AASHO standards. The external cast-aluminum shell is fully sealed against water and dust, and incorporates a sighting device that permits field alignment on the arm assembly by just one person. The rear of the unit is equipped internally with an AREMA-approved terminal strip that allows quick connect and disconnect of light module and external wiring. Hood and background options include 20 or 24 (50.8 cm or 60.9 cm) diameter and high impact plastic or aluminum construction. The LED-based HC-120B light module generates light via a matrix of 360 or 141 high-efficiency LEDs that form a coherent beam when viewed externally. The combined LEDs are brighter than similar incandescent units and consume 40% less power than a comparable incandescent lamp with the same brilliance. As a result, the HC-120 light module helps extend the life of back-up batteries at the crossing location when these batteries are needed. The LED matrix has an estimated operating life of 100,000 hours; in the event a single LED fails, overall beam intensity is reduced by less than 2 percent. Optically, this unit replaces earlier lights with 30 o /15 o, 20 o /32 o, 70 o /0 o spread and deflection patterns. The HC-120B LED light module incorporates a 12 (30.5 cm) hard-coated polycarbonate red lens that is both vandal and water-resistant, and red-tinted to optimize the LED light wavelength. Bright LED side lights (white) are included to enable the locomotive engineer to confirm the flashing light is operational. The module housing is also equipped with air vents and a perimeter rubber gasket for water and dust protection. Selected light modules also incorporate a builtin voltage regulator to ensure against overvoltage damage from the external power supply. Lightning and surge protection circuitry is also provided. The complete light module is mounted in the external housing with four mounting clips, and is connected to the housing terminal strip with two #18 AWG wires. As shown in the ordering tabulation, a retrofit kit version of the HC-120B LED light module is available for direct replacement of 12 (30.5 cm) incandescent lamp units. No special modifications are required on the flashing light assembly or housing when upgrading to the LED lamp.
