iQ-LED Module

Introduction

iQ-LED technology features an all-in-one light source that is capable of recreating numerous other light sources in a test lab environment. In other words, the technology of the iQ-LED can generate custom spectra by the optical mixing of emitted radiation from spectrally different LEDs. Any light source whether it be natural sunshine, automotive brake lights, or a standard light from a lab can be simulated with the iQ-LED device.

The standard module consists of 41 high power SMD LEDs separated into 20 channels on a 10 x 10 cm board. This module can be used as a single light source, or it can be part of an array consisting of multiple iQ-LED units acting as one larger light. By combining the hardware with control software and a NIST traceable absolute calibrated spectrometer, the iQ-LED can recreate your lighting requirements.

The iQ-LED V2 module is built into many of our illumination devices (list below) but is also sold as a stand-alone component module.

The increasing reliance on cameras throughout society today has made it even more imperative to accurately test the performance of a camera in different lighting environments. iQ-LED technology greatly increases the possibilities and the accuracy of camera testing.

Basic Usage

The iQ-LED setup process has been fully automated for an optimal workflow within the control software. A C++ API is available for integration into your design; the API workflow is also fully automated.

 
iQ-LED spectral measurement with EX-2

Measure target spectra (optional)

Use the spectrometer for measuring unique or individual target spectra that are not part of the standard illuminant presets available with the software.

Configure one or multiple iQ-LED

Create an iQ-LED Setup

Select a target spectrum in the iQ-LED software. The light source will be automatically generated based on the target spectrum. Take direct control of the iQ-LED module or upload illuminants or sequences forindependent operation.

Calibrate iQ-LED with EX-2

Verify Light Source(s)

Use the spectrometer to accurately match selected target and iQ-LED device output spectra. Once confirmed, the device can then operate independently without the need of a computer.

 

Main Features

 
High intensity LEDs

High Intensity

The high-powered LEDs are controlled via 4000 steps per channel and 32 kHz PWM (128 kHz via 1000 steps is possible if required by the camera settings). The high intensity allows for broader application areas and more accurate spectral mixing.

Broad wavelength

A Broad Wavelength Range

Multiple channels in the iQ-LED improve the curve fitting for all wavelength ranges. A broad wavelength range of approx. 380 – 820 nm, increases the accuracy of spectral reproduction.

 
Broad wavelength

Independent and Modular

Combine multiple modular units to create one larger light source. After an initial check with the spectrometer to ensure the target spectra is being accurately generated, the iQ-LED device will no longer require a PC and can be run independently until a new spectrum is needed.

iQ-LED production line integration

Production Line Integration

The iQ-LED uses advanced hardware features including temperature sensors, self-testing at startup, and an operation hour counter for smoother integration into production lines.

 

Control Software

The iQ-LED software provides extensive control over all of the iQ-LED devices and their corresponding illumination devices. A C++ API is available for those who wish to use their own software. For detailed information on the iQ-LED software, please see the software page.
