LED panel luminaire from planistar

Luminous surface from planistar for uniform illumination of your application in industrial image processing. Our special edge lighting system provides a very even illumination. Whether for continuous operation or for flash mode, there is something for everyone in our large selection of panel luminaires.

We are also happy to offer you custom dimensions from our in-house production
(simply enquire under sales@no-spam.planistar.de or Tel. +49 (0) 9364 8060-0).

Typical applications of a panel luminaire in industrial image processing

Transmitted light application and incident light application without camera cut-out.

In addition, panel luminaires are used for visual inspection tasks. There are other selection criteria to consider in this area, for which we would be happy to advise you.

Worth knowing about the planistar surface illumination

The origin for edge lighting is planistar. This where the technology was developed and a patent applied for. In the course of the years, planistar’s methods and procedures for illumination were constantly improved and are now used in many areas in our everyday life.

Why transmitted light applications in industrial image processing?

Panel luminaires must be very uniform so that a reliable evaluation of edges or translucent materials can be carried out in conjunction with industrial image processing.

With conventional matrix systems, in which the LEDs are located directly under the luminous surface, the failure of only one LED means that a correct evaluation can no longer take place, because a grey scale fall-off occurs immediately in the measuring surface. In contrast, with the planistar edge lighting system there is usually no noticeable difference in the uniformity of illumination.

The LED luminous surfaces of planistar, on the other hand, remain stable in brightness and illumination over a long period of time. So nothing stands in the way of long-lasting image processing over the entire service period of the image processing system.

What is edge lighting?

The actual light source (mainly LEDs with planistar) is not located under the luminous surface, but outside in the edge. A special light guide with dot matrix system distributes the light evenly or intentionally unevenly over the luminous surface.

This technology also allows a large area to be realised in a very energy-efficient way. Conventional lighting technologies, on the other hand, require vast quantities of LEDs or a deep installation space in order to achieve such a uniform illumination of a surface.

Where does the edge lighting come from?

On 25.6.1982, Gerhard Karl, founder of planistar Lichttechnik GmbH, applied for a patent for edge lighting. This technology is used today in many areas such as smartphones, laptops and televisions.

planistar developed a calculation program and acquired a wealth of knowledge and experience in calculating and producing panel light conductors in various forms.
