Product catalog summary

Introduction
MAZeT GmbH specializes in LED color management solutions under the JENCOLOR® brand, addressing common issues such as color drifts due to binning, aging, and temperature variations in LED systems.

Challenges in LED Color Management

Color Drifts: LED systems face challenges like color drifts due to binning, temperature dependencies, and aging, affecting color consistency and increasing maintenance costs.
Temperature Dependencies: LED brightness and wavelength are affected by temperature changes, with red LEDs being more sensitive than blue LEDs. This can lead to noticeable color shifts.
Aging Effects: LEDs experience brightness loss over time, with significant variations within the first 10,000 hours of operation, impacting color stability and compliance with standards like Energy Star.

Solutions Offered by JENCOLOR®

Direct Regulation: JENCOLOR® offers solutions that include direct regulation via light color using color sensors to maintain LED output stability.
True Color Sensor - MTCSiCF: This sensor provides long-term stability and resistance to temperature drifts, ensuring accurate color perception based on human eye standards (CIE 1931).
Signal Conditioner IC - MCDC04EQ: Converts photo currents to digital signals, allowing high dynamic range performance and integration with LED systems.

Benefits of JENCOLOR® Solutions

Eliminates negative effects of aging, temperature, and color shifts, ensuring long-term stability and reducing maintenance costs.
Supports compliance with standardized color values and regulations.
Utilizes interference filter technology for accurate color measurement, avoiding drift effects common in absorption filter-based sensors.

Comparison of Filter Technologies

Interference Filters: Offer high color accuracy, no drift effects, and a wide temperature range up to 100°C.
Absorption Filters: Limited by wavelength drifts and lower dynamic and temperature ranges.

LED COLOR MANAGEMENT SOLUTIONS THE PROBLEM: COLOR DRIFTS AND ACCURACY LOSS DUE TO BINNING, AGING & TEMPERATURE Aside of the benefits of LEDs, the technology also comes with many downsides that can result to serious problem during the development. The most common problems and interference factors are color drifts based on binning, temperature dependencies or aging of LEDs. These effects cause major problems if it is the goal to maintain standardized CCT, color values or color brightness levels. Especially, when looking at not only one but multiple illumination fixtures or lighting systems. High...

LED COLOR MANAGEMENT SOLUTIONS COMPARISON OF FILTER TECHNOLOGIES THE BENEFITS OF INTERFERENCE BASED SENSORS The secret behind MAZeT’s sensors is the worldwide unique JENCOLOR® interference filter technology. Interference filters with micro stacks only let specific wavelengths reach the detector and do not drift in wavelength over time or via temperature influences. Other than absorption filter based sensors (standard of common color sensors), the interference filter technology does not rely on degradable filter materials. Therefore, they are an ideal solution for long-term stable compensation...
