Light tunnel (light dome) from planistar

planistar’s LED light tunnel is an improved way of more easily integrating conventional dome lighting into an industrial system. The test pieces can be completely inserted into the light tunnel. This is usually not feasible with a light dome.

Important: The desired lighting effect can only be achieved if the tunnel or dome is used correctly. In addition, planistar light tunnels are much more flexible in their dimensions than the typical hemisphere of LED dome lighting.

We are pleased to offer you custom dimensions from our in-house production
(simply enquire under or Tel. +49 (0) 9364 8060-0).

Typical applications of light tunnels in industrial image processing

Transmitted light application as well as incident light application with or without camera cut-out.

Here many adaptations to the conditions are possible in terms of height and size. We will be happy to help you find the right dimensions.

Overview of our luminaire groups

We offer a variety of different types and sizes for your inspection tasks in industrial image processing. The equipped colour temperatures range from a daylight spectrum of approx. 5000–6000 K (Ra > 85) to all common monochrome colours.


LED light tunnel for continuous lighting applications

Our light tunnels consist of three panel luminaires which are covered with a semi-circular diffuser. So we have no indirect lighting, but in actual fact an active illuminating surface in the entire LED light tunnel. The light tunnel can be de-energised by means of an optocoupler switch input.

Our LED light tunnels can be equipped in many colours up to RGBW.

LED light tunnel for continuous and flash mode, dimmable

Whether continuous operation or flash mode: The light tunnels are designed for both scenarios. In this way, both modes are available for the visual inspection task on site. The operating mode must not be defined until the LED tunnel is set up. In addition to the switch inputs for continuous and flash mode, the luminaire has a 1–10 V interface for external brightness control. From 1 V at the interface, the luminaire automatically switches to interface operation; a mechanical changeover at the built-in controller in the LED panel luminaire is not necessary.

The LED panel has a built-inmicro controller which monitors the currents, the duration of input signal, and the pulse/pause ratio in flash mode. In this way, operating errors are excluded and overloading of the LEDs is prevented.

A special feature of the Xled light tunnel is the cosine correction, which provides even more uniform illumination for the measurement application in the image processing system.

Many adaptations possible

We manufacture the individual main components of the light tunnels ourselves. This allows us to adapt them very well to your image processing task.

  • The LED light tunnels are completely variable in length, width and height. They can be completely adapted to the conditions prevailing with the image processing system.
  • To further improve the light tunnel, white side panels with openings for the test pieces are fitted to the luminaire.
  • Openings for cameras can be made not only in the upper surface, but also at the side edges.
  • The openings can be bridged with coaxial luminaire, so that no dark surfaces are visible through the lens with shiny objects. The brightness levels are adjusted.
  • Several switch inputs can be integrated so that both sides and the upper surface can be switched separately.

An exact task description of your desired image processing system including space constraints helps us to determine the most suitable external dimensions.

Any questions?

We will be happy to advise you on the design and dimensions of the light tunnel you need for your application. We respond to your needs and give you individualised advice. Your task in industrial image processing is our priority.
