The forestry environment offers a unique set of challenges for both machinery and lighting. It is also where TYRI began their journey. TYRI work lights have been built to illuminate the forest and ensure that you are able to continue to work safely no matter the amount of light filtering through the canopy.
Working with OEM’s, we can design work lights that sit perfectly on your machine and provide the maximum usable light to the area you need it the most. Using the latest technology, we take a view of the actual vehicle design along with any of its parts which may obstruct the light. This, coupled with a view of the terrain and application, enable us to determine and design the best possible solution to your lighting requirement.
TYRI test and approve all work lights under some of the toughest conditions in the industry to ensure they will not fail. Available in a wide selection of lumen output and voltage options to suit your needs, TYRI is the leading name in heavy vehicle lighting.
With a finger on the pulse of the industry, the TYRI Research and Development department ensure they are ahead of the curve with new technology and trends, developing new solutions to meet these future needs. Read more about the latest lighting technology and how TYRI can help you in our magazine.
The tracked vehicles with forestry mulchers are specially developed for difficult tasks, such as land clearing and vegetation management where LED work lights are needed to meet highest requirements for performance and durability. Uniform lighting around the whole machine to make sure that the machine operator has a clear view on his working area.
Harvesting wood in rugged parts of the forest requires reliable forestry machines as well as reliable and robust LED work lights that have undergone the strongest vibrations tests. TYRI LED 1010 with 2500 effective lumen are mounted to this forestry machine to give excellent light coverage around the machine.
Vimek is a manufacturer of light machines for forestry thinning. TYRI LED 0909 work lights were chosen for their harvesters, forwarders, and combi-machines, due to their design and ability to provide a uniform light to the work area. Highest EMC class to avoid radio interference.
The challenge was to create a suitable lighting solution for this timber truck because of varying distances between truck and trailer. TYRI LED 0909 work lights and 0909 e-approved reverse lights were used.
INTELLilight with the ability to change colour temperature from 2 700 K to 6 500 K and automatic dimming function is ideally suited also for forestry machines to solve lighting problems in difficult weather conditions such as snow and dust.
Testing and approvals for forestry
EMC EN55025 / CISPR 25
It is of vital importance, especially on emergency or military vehicles, that lighting does not affect control systems, cameras, on-board computers and other radio sensitive equipment. This is why TYRI lights are scrutinised to ensure they do not interfere with EMC functionality.
IP 69K ratings offers complete peace of mind that the work light you are installing has undergone rigorous tests to ensure it is both durable and conforms to the highest standards on the scale of protection against water, moisture and dust ingress.
TYRI lights undergo extensive vibration testing, for up to 8 hours on all axes, above 10 Grms at a frequency range from 5 – 2000 Hz. This simulates the forces applied to the lights once mounted on off highway machines.
Salt spray testing
TYRI lights undergo rigorous salt spray testing to ensure they are approved to ASTMB117 standards. This ensures that even in corrosive environments, TYRI lights will continue to perform.
As well as vibration testing, TYRI lights undergo shock testing to a force of 50G. This ensures that TYRI lights will withstand punishment from your work environment.
TYRI lights tested in hot and cold temperatures, as well as humidity, for a minimum of 50 days. They are tested in conditions up to -40C° to +85C° and up to 90% humidity.
Polarity / Overheating / Overvoltage Protection
TYRI lights have built in temperature sensing circuits which reduce the output to regulate the temperature of the light. This prevent damage to the LED’s that can result in premature failure. TYRI LED lights are also reverse polarity protected in the event of incorrect installation. Should the wires become crossed during connection, TYRI lights will not turn on until the wires have been connected in the correct configuration, protecting the LEDs and associated circuitry.
