Architectural Illumination

RGBW LED dots for light sculptures and media facades

  • Carl Stahl is already using LED dots in its X-LED product. The individually controllable LED dots are connected with a specially developed five-core ribbon cable. These are attached to nodes in nets, between ropes or on other supports. In this way, they form an illuminated screen of any size for two- and three-dimensional multimedia presentations. Integrated processors in each luminaire ensure the necessary flexibility for dynamic image transitions and colour uniformity.
    Images, animations and videos are transferred directly to the system via standardised interfaces. Specialised software enables real-time video rendering and the programming of interactive, creative lighting designs.

    ​

    • RGB(W) LED dot with higher luminous intensity

    • Longer service life and therefore future-proof

    • Two versions (Medium / Premium)

    • LED dot in two versions. The premium version is operated with 24 V via a switching regulator, the light intensity has been increased to > 55 cd (2.1 watts).

    • The Medium version is operated with 12 V without a switching regulator and achieves a light intensity of > 20 cd (1.2 watts).

    • A set is supplied consisting of an upper part (housing with moulded electronics), a lower part for contacting the ribbon cable and silicone sealing rings to seal the ribbon cable against the housing.

    • Dimension: 30 x 30 x 15 mm

    • PCB material FR4

    • LEDs: Medium: 2 x RGB(W) / Premium: 4 x RGB(W)

    • Service life > 50,000 h

    • Dimmable (DMX)

Disinfection in the hearse

UV-C LED modules Violet for HARTUNG

  • The company HARTUNG BESTATTUNGSWAGEN in Suhl specialises in converting cars for transporting coffins. Many bacteria and viruses lurk in hearses, which are combated using various materials and techniques. In order to further improve hygiene in the transport area, HARTUNG has been looking for effective and affordable ways to help its customers in their day-to-day funeral work and minimise the risk of infection with pathogens. HARTUNG is thus responding to a new demand situation that has arisen during the pandemic, as special instructions for handling SARS-CoV-2-infected deceased persons are recommended.

    • Improved hygiene in the coffin room through sterilisation of the room surfaces and on the coffin

    • Effective UV-C system with energy-saving LED technology

    • Suitable control system with safety precautions to avoid danger to people

    • Use of the UVC system as a mobile solution by feeding it via the car battery while driving

    • Robustness against shocks and vibrations when driving

    • Easy installation and maintenance of the UV-C system

    • The project was realised with four Standard Violet UV-C LED modules.

    • The UV-C lights were positioned in such a way that all surfaces in the coffin room were reached in the best possible way.

    • Prior to installation, an optical simulation was used to ensure that the radiation flux of the UV-C lights would realise optimum results and to check how much optical power would reach the surfaces. This was used to determine the duration for effective sterilisation during driving times

    • The "Power Controller" control unit was adapted in-house for mobile use and provides safety precautions to avoid contact with people.

    • Instead of the on/off button provided in the standard module, the power supply unit is now switched simultaneously with the ignition of the hearse. This activates the UV-C lights during the journey. The second "Door" button has also been inverted for this purpose: Normally, the interior lighting in vehicles is switched on as soon as doors are opened - here, however, the reverse effect has been implemented, namely that the closed door gives the signal that the UV-C LEDs can switch on safely.

    • 4 x ready-to-use UV-C LED lights Violet UVC LED module, 275nm

    • 275nm peak wavelength with 12 Seoul Viosys UVC LEDs

    • Constant current operation with 450 mA

    • Cover incl. UVC optics from LEDiL

    • Robust aluminium housing

    • Power Controller control platform - was customised for the project

High Performance Indoor Environment

LED-Modules for the Fraunhofer testing laboratory

  • As part of an investigation into the effect of full-spectrum LEDs on people indoors, the HiPie laboratory (High-Performance Indoor Environment) at the Fraunhofer Institute for Building Physics (IBP) was equipped with LED modules from LUMITRONIX®. These were fitted with LEDs with different color rendering indices and color temperatures. The LED modules were pre-assembled on supports for easier installation. They were also controlled via DMX and DALI.

    In the HiPie laboratory at Fraunhofer IBP, building physics room parameters such as acoustics, light and climate can be influenced in a targeted and variable manner so that their effect on people can be investigated. A daylight wall enables the simulation of solar radiation through windows, taking into account the changing light conditions during the course of the day. In combination with freely configurable artificial lighting scenarios, all relevant lighting situations can be represented.

    ​

    • LEDs in three different color temperatures (2700 K, 4000 K, 6500 K)

    • Various spectra (2x full spectrum, 1x standard CRI 80, 1x RGBW)

    • Average illuminance of 2000 lux at the workstation (depending on LED type)

    • DMX and DALI control

    • Mounting of the LED modules on brackets for faster installation

    • Equipping BackMatrix LED modules with 6 different sunlight spectra each in 2700K, 4000K and 6500K from two different LED manufacturers (SunLike from Seoul Semiconductor & Optisolis from Nichia)

    • Assembly of BackMatrix LED modules with red, green & blue LEDs as well as 3 different standard CRI-80 spectra in 2700 K, 4000 K and 6500 K (Nichia)

    • The Fraunhofer Institute can thus freely control 2700 K, 4000 K and 6500 K in three different specific spectra in the laboratory and can also add red, blue or green light to further fine-tune the lighting effect.

    • This is controlled via DALI with Meanwell HLG-240H-24B power supply units, to whose dimming input the DALI interface is connected.

    • We pre-assembled and wired the BackMatrix modules on the panels so that they could be inserted directly into the luminous ceiling at the Fraunhofer Institute.

  • Backmatrix LED modules

    • Constant voltage: 24V

    • Number of LEDs per module 49

    • Circuit board: FR-4, 1-layer

    • Solderless connection possible via insulation displacement terminals

    • No cooling required

    • Simple installation

    • Dimensions: 280x280x7mm

  • Do you have any questions or need help with another project?
