Light tunnels from planistar are used wherever shiny objects need to be illuminated diffusely and without shadows. Thanks to their tunnel shape, they are easier to integrate into production systems than conventional LED domes.
The special feature of our light tunnels is that the surfaces really light up actively and are not just illuminated indirectly as with a light dome.
The tunnel shape allows the test piece to be fully immersed in the tunnel, so the desired lighting effect is fully achieved.
If you cannot find a suitable solution in our extensive standard range, we will be happy to offer you LED lighting to suit your requirements.
As we are the manufacturer of the LED tunnels ourselves, we can offer customized luminaires with short delivery times and at reasonable prices.
Light tunnels from planistar have 3 actively illuminated surfaces with edge lighting and a curved diffuser. This creates a kind of light dome that emits very uniform and diffuse light onto the test objects. The cut-out is individually adapted to the inspection task, camera position and lens.
Due to its design, the tunnel can be adapted in length, width and height to the mechanical requirements and the camera distance. This is not possible with a conventional light dome.
The tunnel lighting can be triggered without power by an optocoupler switching input. This reacts to every rising edge from 5 V TTL to 24 V PLC.
No further external controllers are required, everything is built into the light.
For a wide range of applications in machine vision, the tunnel domes can be equipped with different shades of white, but also with monochrome light colors from approx. 380 to 940 nm. IR and UV are implemented in a matrix arrangement due to the technology.
This is precisely where our strength lies. Because planistar manufactures the lights in-house, we can produce customised backlighting with short delivery times.
So you don't have to follow our standard programme. We adapt exactly to your requirements and the conditions on site.
This saves you costs in theOur production processes are planned in such a way that a customised light has almost the same throughput as a standard light. The only difference is that the customised luminaire is precisely documented. This means that we are able to supply replacements even years later.
Benefit from the co-operation with planistar.
Lights direct from the manufacturer
When revising the product series, we always take sustainability into account, as many small details add up to a big picture.
This starts with saving resources and energy, the right choice of materials we use, right through to packaging and disposal.
Most of our lighting works with edge lighting and a light guide. As planistar had the patent for the edge lighting of light sources and light distribution using a dot grid, we also have the knowledge to calculate and produce any size.
Our surface light guides have the advantage of maintaining uniform light distribution over the entire service life. The failure of an LED row in the edge area has virtually no effect on the uniformity in the measuring range. With a matrix system, on the other hand, a dark spot is immediately visible.
For some applications, however, a conventional matrix system is more suitable. Thanks to our sophisticated design of these lights, we can also supply you with devices with good homogeneity and very high light intensity. These reflected lights for image processing are usually very bright, making it possible to reduce motion blur with short exposure times.
A light dome is often illuminated indirectly via the bottom edge of the housing. However, this results in a lot of light loss. In addition, direct light can enter the lens through the camera opening.
With tunnel lighting from planistar, on the other hand, we work with 3 area lights and a curved diffuser to shine directly onto the test object. In this way, the test object is illuminated more brightly.
With the help of our machinery, we are able to produce both very small and very large LED lighting.
The example shows a light tunnel with a length of 1800 mm and a long slot for a line scan camera.
Thanks to the diversity of our production options and the high level of vertical integration, we can always adapt to the conditions of our customers' image processing tasks and offer an optimum solution for all aspects of lighting.
A conventional hemispherical light dome is an ideal solution.
So much for the theory. Now we come to the practice:
The light tunnel from planistar, on the other hand, can be realized in any dimension for any working distance. The tunnel shape makes it ideal for mounting over a conveyor belt.
