HELLA: New full-LED rear lamp for 24-volt truck and trailer applications

• Customisable and durable full-LED rear lamp creates high recognition value
• Patented LED light curtain ensures high level of safety and visibility
• Pioneering concept enables adaptation of sensor technology



Individualisation, safety and future viability: these three keywords characterise the new full-LED modular rear lamp that lighting and electronics expert HELLA, has launched especially for 24-volt truck and trailer applications.

The patented HELLA LED light curtain, which creates the tail light of the full-LED rear lamp, can now, for the first time, be customised. Graphic structures such as dots, stripes and shapes can be marked out for this purpose. "This makes the tail light the central eye-catcher and underpins the branding of the manufacturer’s on the road. Trucks and trailers can therefore become unique," says Georg Fink, Sales Manager for Trailers at HELLA. "An individual light signature is ultimately becoming more and more important in order to stand out from the competition and this is true not only for car manufacturers, but also for those producing trucks and trailers."

Furthermore, manufacturers are free to choose the colour of the carrier frame, so as to match, for example, the corporate colours. "The lens placed above is available in red or clear so that the colour of the design then becomes visible," explains Fink. As a further customisation option, manufacturers can choose whether the direction indicator light is to be the standard type or the dynamic variant.

In addition to the customisation options, HELLA has also further developed, in-house, the light curtain technology. The result is a much more homogeneous appearance of the tail light, as it does not require separate optics. At 144 square centimetres, the light curtain is also almost twice as large as in previous models – so the tail light is always visible, even at dusk or in fog, and from a distance.

With an installation space of only 55.5 millimetres in depth, the full-LED rear lamp has technical features that make it fit for the future. Thanks to mechanical interfaces for sensor technology, ultrasonic sensors can be connected on both sides, for example, in order to implement a parking assistant. In addition, the control for the flashing side marker lamps, the direction indicator failure control and the load simulation designed to monitor the stop and direction indicator lights, are all integrated into the system. This eliminates the need for additional control units, a fact which significantly reduces the amount of wiring required and ultimately saves costs.

The full-LED rear lamp is designed for the voltage range of 24-volts. The two-colour outer lens is made of impact-resistant polycarbonate (PC) and bonded to the housing. Overall, the rear lamp achieves protection class IP 6K9K, which means that it is not only dustproof, but also resistant to cleaning with water under high pressure. The lamp also complies with the automotive standard (ISO 26262) and is available with or without a rubber arm. As a standard interface to the vehicle, it has a central 7-pin DIN connector and 2-pin AMP SUPERSEAL connectors for auxiliary lighting functions.
