LED and Luminaire Light Flicker Analyzers: Function and Manufacturers

This page covers light flicker analyzers used for LED and luminaire flickering tests including its benefits. It describes how an LED light flicker analyzer works and lists luminaire light flicker analyzer manufacturers.

Introduction: Understanding Light Flicker

Modulation of light output is known as flicker. All electric light sources running on AC power modulate their light output to some degree.

Here are some potential implications of flicker for human beings:

• Neurological problems such as epileptic seizures
• Headaches, distraction, fatigue, eyestrain, blurred vision
• Apparent slowing or stopping of motion
• Reduced visual task performance

Flickering in LEDs and luminaires can be caused by driver faults, environmental conditions, power supply temperature issues, and/or LED loads. A light flicker analyzer helps in detecting flicker and also displays safe limits. It’s typically a portable piece of equipment that measures percent flicker, flicker index, and fundamental frequency.

This helps manufacturers determine whether an LED or luminaire under development is within safe limits as defined by industry standards. The instrument usually consists of a high-speed photometer head to capture high-speed waveforms. A detachable computer panel might also be available with the analyzer for user operation at their convenience.

Figure 1 (not included here but conceptually present) depicts the testing of a luminaire using a light flicker analyzer.
