Frequently Asked Questions

What sizes and shapes are available in the DL8 series?

The DL8 is built on a modular 50 × 50 mm tile architecture, so the active emission area is available in 50 mm increments from 100 × 100 mm up to 500 × 500 mm; intermediate sizes and custom geometries are produced on request.

Which LED colors and wavelengths does the DL8 series offer?

Each DL8 model is available in Neutral White 5000K (WHI), Standard Blue 470 nm (BLU), Red 625 nm (RED) and Infrared 850 nm (INF).

How does the DL8 keep the illumination uniform?

An integrated MCCD© (Multi Constant Current Driver) keeps the current constant across the whole LED matrix, so light output and homogeneity remain stable even when the supply voltage fluctuates.

Can the DL8 be used as a backlight, and how is it protected for industrial use?

Yes: besides direct illumination, the DL8 works as an economical backlight by adding a diffuser glass. It uses patented HTTM© (High Transmission Thermal Material) for heat dissipation, a frameless ultra-slim anodized aluminium housing, a dedicated glass cover protecting the electronics, reverse-polarity protection, and supports continuous, ON/OFF and PWM control.

Technical insights

HTTM© Technology — High Transmission Thermal Material

Thermal management is one of the most critical factors determining the long-term performance of an LED illuminator. Excessive or uneven junction temperature is the primary cause of luminous flux degradation, chromatic shift, and reduced LED service life in industrial lighting systems.

RODER addresses this challenge with HTTM© technology, a purpose-engineered thermal interface solution integrated into every next-generation illuminator.
A layer of electrically insulating, high-thermal-conductivity material is precisely interposed between the LED printed circuit board and the aluminium
housing.

This material acts as a highly efficient thermal bridge: it prevents any electrical contact between the PCB and the enclosure while channelling the heat generated by both the LED array and the driver electronics directly and uniformly into the aluminium frame, which acts as the primary heat sink.

Compared to conventional air-gap or standard thermal pad solutions, HTTM© achieves a substantially lower and more uniform steady-state LED junction
temperature.
The direct consequences are: extended LED service life, stable luminous flux output over tens of thousands of operating hours, and consistent chromatic coordinates throughout the product lifetime — all critical requirements for reliable, long-term photometric calibration in machine vision systems.

MCCD – Multi Contant Current Driver

This is the MCCD architecture implemented by RODER.

Each column of the LED matrix is powered by its own dedicated, independent constant current source. The three sources share a single PWM/ON-OFF input that guarantees simultaneousswitching of all columns.

Advantages

  • Spatial Uniformity: Consistent luminance across the matrix, independent of Vf variability between batches, devices, or over time.
  • Thermal Compensation: Drivers autonomously offset thermal drift per string, maintaining stable current even under non-uniform heat gradients.
  • Strobe Synchronization: Shared PWM ensures simultaneous switching, eliminating intercolumn jitter—critical for global shutter cameras.
  • Lifetime Stability: Column-specific compensation for differential LED ageing preserves photometric uniformity throughout the product’s life.
  • Calibration Repeatability: Fixed luminance over temperature and time ensures vision system calibration remains valid without periodic adjustment.
