Optimising performance with intelligent work lamps
THE ROKLUME 280N SMART IS THE LATEST ADDITION TO FORVIA HELLA’S PORTFOLIO OF LIGHTING SOLUTIONS DESIGNED TO OPTIMISE VISIBILITY AND WORK PERFORMANCE
ᐅ In the off-highway industry, working conditions can often be harsh with dust, rain, snow and fog impairing visibility. For this reason, effective work lighting is crucial for safety and productivity. White light, which is available as standard with LED work lamps, is suitable but only to a limited extent as it is more reflective and can therefore cause a glare.
The experts in lighting and electronics for the off-highway industry at Forvia Hella have developed the RokLume 280N Smart. The innovative product has been designed for vehicles in various industries, from mining and construction to forestry.
Improved visibility
The RokLume 280N Smart allows the light colour to be adjusted depending on the environment to maximise visibility. It offers three colour variants: white-green, white-amber and white only. Green or amber light is used when visibility is very limited, during harsh weather conditions or high dust levels, for example. The coloured light penetrates dust, rain, snow and fog better than conventional white light. The improved visibility reduces the risk of accidents and relieves the strain on the worker’s eyes.
Another advantage is that the colour temperature can be continuously adjusted from warm white to cool white. Warm white light minimises eye strain and fatigue in reflective environments, while cool white light is perfect for clear vision during night-time work in good weather conditions. The dimming function allows the work lamps to function economically as daytime running lights. This reduces power consumption and CO2 emissions.
Light control
If the RokLume 280N Smart is retrofitted, the smart functions are controlled via a control panel. This is mounted on the dashboard in the vehicle. meaning the driver does not need a mobile phone or remote control to adjust the light. An integrated memory function allows up to three individual light settings for the work lamps to be saved which can be called up at the touch of a button. Operation is intuitive and the buttons are dimensioned so that they can be easily operated even when wearing gloves.
For original equipment manufacturers, operation can be integrated via the human machine interface (HMI). The gateway uses the CAN bus J1939 protocol to communicate with the control element or the customer’s HMI.
Ease of installation
A key advantage of the RokLume 280N Smart is that it communicates via powerline communication (PLC). Unlike systems that generally rely on wireless connections such as Bluetooth, PLC ensures a stable, reliable and interference-free communication channel. This wired communication method utilises existing power lines. This removes the need for additional harnessing making installation simple and straightforward. A central control unit (gateway) is installed in the vehicle, which reaches each work lamp via PLC.
Durability
The RokLume 280N Smart is designed for demanding conditions in mining, on construction sites and in forestry. The work lamp and gateway have protection classes IP6K8 and IP6K9K, preventing dust and liquid from penetrating the housing. The control panel also has a robust IP6K7 rating and is designed for a working range of -40°C to +90°C – meaning it can withstand extreme temperatures.
The RokLume 280N Smart is available in six different light distribution variants: long-range, close-range, pencil beam, diffuse flood, tunnel flood or Zeroglare illumination. The intelligent lighting system is also equipped with a lifetime warning. This provides a timely warning before the service life of the individual work lamp expires, thus preventing unplanned downtime. Anti-theft protection has also been integrated as an additional benefit.
