Light tunnel according to customer specification

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 the
  • Concept of the system,
  • Construction and in the
  • Evaluation in industrial image processing.

Our 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.

Sustainability at

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.
 

  • Materials are carefully selected (Reach and RoHs)
  • Optimization of electronics and thermal management to extend service life
  • Manufacture of lights and electronics in Germany
  • Reduction in raw materials with the same properties
  • The materials can be recycled at the end of their service life
  • Packaging is 100% recyclable

Why LED bar lighting from planistar?

Thanks to our many years of experience in the development and production of lighting technology for a wide variety of areas, we have been able to continuously optimize our LED luminaires and adapt them to the increasing requirements of our customers.

Lighting technology

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.

Direct vs. indirect light

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.

From small to large

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.

Dome lighting as the ideal solution - so much for the theory

A conventional hemispherical light dome is an ideal solution.

So much for the theory. Now we come to the practice:

  1. Dome lighting only develops its full lighting effect when the test item is immersed in the illuminated dome. This is precisely where the problem lies. In most cases, this is very difficult or even impossible to achieve. If a dome is mounted at a distance above the test part, the lighting effect is similar to that of a conventional and cheaper surface light.
  2. In addition, a conventional dome cannot be produced in every dimension. The diameter automatically determines the height and therefore the camera distance. Here, the user must rely on standard dimensions and adapt completely to the dimensions.

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.
