New Vision Worklights You Can Always Work In The Dark Night
1. Why New Vision LED worklights?
NV combines innovative technologies and know-how from the agricultural industry with the high requirements made of commercial vehicles (robustness, durability, etc.).
Our LED work lights are already subjected to the hardest endurance testing in the development phase to ensure that they work reliably in the rough and tumble of hard environment, and so that an extremely long design life can be attained.
2. Which worklight is the right one for me? To be able to make this decision, you should ask yourself 3 questions first of all:
- What needs to be illuminated? (an object, a surface, an enclosed space, etc.)
- Where would I like to / am I able to attach the worklight? (available space, attachment options, etc.)
- What height is the worklight to be attached at?
Answering these questions will help you to choose the right one from the wide range of NV worklights on offer.
We recommend using the Isolux diagrams to compare the various illumination options provided by the worklights.
These diagrams show the illumination provided by various worklights at an installation height of 2.5 meters and a tilt angle of 8°.
If you have thought about these 3 questions, then you can use the sketches and technical data which you will find with every LED work light to select the right product for your application.
If not, then we recommend you can contact our technical engineers to supports, so that you conveniently see the different illumination options our worklights have to offer.
3. How long is the design life of NV LED work lights?
The design life of a worklight depends greatly on external influences, such as vibration, salt contamination or ambient temperature.
The design life of the LED is usually very long, however, it is reduced by high temperatures.
Worklights are often maxed out to their limits which leads to the LEDs overheating quite quickly, reducing the luminous efficiency and also the design life.
NV worklights in contrast are equipped with active thermal management which prevents the lights from overheating.
Thanks to this active monitoring, NV LED worklights often attain an unsurpassed design life of up to 50,000 operating hours.
4. How many lumens does a great LED worklight have?
When selecting your worklight, the lumen should not necessarily play the most important role, because a high lumen value alone provides no guarantee that the illumination will be good, not to mention a good distribution of the light in your work area.
The “lumen” value only tells you how much light a light source (e.g. LED) gives out.
The challenge the manufacturer is faced with is to capture the light beams, concentrate or scatter them, and to make them shine on the ground in the required work area.
When selecting the right LED worklight, you should not only rely on the lumen data on the datasheets.
Many manufacturers only state the calculated lumen, which may differ considerably from the actual lumen measured.
Make sure you look to see if the light datasheets states “Lumen measured”. Here is an article to show you the Lumen measure
5. What is thermal management and why is it so important?
Depending on the type of LED, with operating temperatures of more than 120°C the design life is significantly reduced.
To dissipate the heat from the sealed light requires a sophisticated thermal management concept.
Passive thermal management:
Here, the heat from the LEDs is dissipated by the worklight. This effect is generated by using high-quality heat-conductive materials, such as aluminum or special plastics, and also using heat-conductive film and cooling fins on the housing.
Active thermal management:
Here, temperature sensors are used which control the temperature range of the LEDs.
If they get too hot, then the electronics on the LED work light actively intervene and lower the power of the device until the optimal operating range is reached again.
This effect is virtually invisible to the naked eye but is of essential importance to the design life.
