On an aircraft, critical safety and operational information is relayed to pilots and passengers primarily via artificial light. Integrated displays, cockpit controls, indicators, illuminated signs, navigation lights, and other electronics provide the necessary data to safely and accurately guide an aircraft to its destination and ensure the comfort of its occupants.

HOPOOCOLOR Imaging Colorimeters and Photometers feature a tristimulus optical filter system scientifically engineered to simulate human visual sensitivity to brightness and color, which enables accurate evaluations of illuminated components that reflect an operator’s or passenger’s perception—whether a display, character, sign, or ambient light distribution pattern—ensuring all illuminated components meet requirements for safety and operability.

Airborne display

The airborne display system is one of the important man-machine interfaces between pilots and their surroundings. The airborne display system needs to provide pilots with appropriate, timely and accurate data in a more flexible way, ensure pilot safety and provide necessary information. The airborne display system needs more and more display devices with high brightness, high definition, high contrast and anti-extreme environment.

HOPOOCOLOR Imaging Colorimeters and Photometers testing flat panel displays (FPDs), smart devices, touchscreens, infotainment and navigation displays, and more. Radiant cameras evaluate LCD, LED, and OLED displays and display components, including backlight units (BLUs) and LCD modules, as well as see-through displays like augmented reality (AR) and head-up displays (HUDs), for performance in a range of ambient light environments, from day to night, in all weather conditions.

HOPOOCOLOR Imaging Colorimeters and Photometers carries out display test including luminance, luminance uniformity, chroma test.Display tests support standardized measurement practices such as those recommended by SAE International for displays, HUDs, and illuminated components (for example, ARP4260B, which contains colorimetric and photometric measurement guidelines for airborne electronic flat panel display systems).


Indicator lamp measurement

Digital avionics continue to replace analog components in the cockpit and controls in the cabin, making light and color accuracy evaluation increasingly critical. Indicators, gauges, controls, instrument panels, and illuminated signs provide vital performance, instructional, and safety information, and many backlit components must comply with standard luminance and color thresholds for adequate intensity and distribution under all lighting conditions.

Designed specifically for backlit symbol measurement, HOPOOCOLOR Imaging Colorimeters and Photometers have feature a powerful software tool, Ensure uniformity of brightness and chroma (user specified CIE C X, cy values).


Evaluation of internal lighting

Aircraft interior lighting can be divided into cockpit and cabin lighting, systems industry can be subdivided into reading lights, ceiling and wall lights, indicator lights, toilet lights, floor path lighting stripes, and others.From the perspective of terminal applications, aircraft internal lighting system can be applied to narrow-body aircraft, wide-body aircraft, regional aircraft and other fields. Internal lighting must be adequate based on the distance or angle of installation within the aircraft to ensure compliance.

Lighting that is too bright or poorly oriented may not meet aircraft operating specifications. In addition, luminance and chromaticity uniformity are also important for function and quality perception.


External light source testing

Airport terminal building lighting is a combination of architectural beautification, human engineering and aviation safety. It is different from ordinary civil building lighting, but has higher requirements and aesthetic public buildings. It can provide full data of HID, LED and other light sources to achieve the best external light source design.

The design engineer can easily generate a standard output file for creating a complete near-field model. The imaging colorimeter can measure the luminescent intensity distribution pattern, the limit value and the illumination distribution to ensure that the lighting equipment meets the related requirements of the aerospace lighting standards.
