AEC Project


AEC R&D department keeps working on the development of “Comfort Light Optic”: AEC total reflection optical system allowing to manage the LED source by means of reflectors and protection closure screen.
A high professional team of engeneers hardly work to improve the quality of AEC optical systems by means of high efficiency aluminium reflector and tempered glass screen.
This extraordinary combination of materials, ensures high quality, high efficiency and easy cleaning products.

The design of “Comfort Light Optic” allows:

- to maximise the luminous efficiency
In terms of luminous efficiency, “Comfort Light Optic” contributes to reducing refraction and reflection losses inside the optical unit.
The optics protected by the glass, ensure the maximum product performance in enviroments subject to particularly conditions where the optical performance and the luminous efficiency of the device tend to decrease as a result of pollution (tunnel).

- to obtain the best lighting performance
AEC "Comfort Light Optic" offers high lighting performance in terms of distance between the poles and the unevenness on the road.
Its high efficiency, allows to maximize the luminance and illuminance levels in full compliance with the international regulations and energy saving standards.
The total optical reflection finds its essence in the use of high quality materials, such as V0 self-extinguishing polycarbonate with aluminium finish or pre-anodized aluminium in A+ class energy.

- to protect LED source
AEC adopts an high transparency, in order to optimize the efficiency of the luminaire, and also able to ensure the maximum protection of the LED light source from shock and external agents.

- to properly address the light
AEC “Comfort Light Optic” can utilise every single LED light emission.
The optical system is composed of multiple reflector arrays which can be formed to achieve the photometric geometry depending on the required applications.AEC has also developed various types of optics to be applied to the different geometries of installation, requested by the market.

- to guarantee luminaires photobiological safety
AEC “Comfort Light Optic” minimizes the level of glare from the light source in compliance with the safety requirements imposed by the standard relating to laser sources.
The reference standard prescribes a classification drawn up in order to preserve the observer from potential photochemical and photobiological damages.
The determination of the safety class is a compulsory requirement for CE mark.
According to EN 62471 reference standard AEC LED lighting systems are included in an EXEMPT GROUP CATEGORY (no photobiological risk).

The mechanical design procedure takes advantage of an advanced mathematical modelling system, using the latest 3D CAD software systems.
The use of high precision CNC robotic machining with technology up to 5 high precision axis and high level of processes automation, allows the monitoring and optimization of every single phase of the process and provides excellent results.
The heat dissipation system designed by AEC is efficient and able to guarantee high performance in terms of thermal resistance.
In fact, the R&D department uses sophisticated simulation software able to predict the thermal behaviour of the heat sinks, directly designed by AEC mechanical designers.
The advanced systems of thermal measurement and the accurate calculation of reliability, according to the latest methods of prediction and functional evaluation, allow to optimize the project and to estimate the luminaire expected lifetime.

The thermic tests are carried out to validate the heat sink design.
All tests performed in AEC thermic and climatic rooms ensure the thermal design functions across a range of temperatures from -40°C to +50°C.
These tests are undertaken within AEC certified in-house laboratories.


Electronic components play a key role in defining the reliability and overall performance of a lighting fixture, irrespective of the technology (HID or LED) and the insulation class (class I or II).
This is the reason why remote control electronic boards and power supply units must be carefully chosen and tested for electrical safety and performance, both in normal operation and under stress state (electrical, environmental, ...).

The power supply units, selected after a deep analysis, must be safe and efficient.
In order to reduce losses and increase the luminaire efficiency, the power factor has to preserve a high value even in case of limited load and dimming.
The LED current must be controlled and kept constant throughout the whole lifetime of the device, so as to ensure the performance and durability of the optical unit .
Control interfaces such as 1-10V or DALI and power supply unit programming systems are essential to achieving the goals of energy saving, increasingly required by the market, and to handle the lighting fixtures managed through remote control systems .
The study carried out by R & D department, has allowed to improve the power supplies, which guarantees the maximum protection to the internal in case of overtemperature, overload , short circuit or LEDs circuit opening.
Finally , the power supply unit must be provided with all the necessary European certifications concerning performance, electrical safety and electromagnetic compatibility .

Electrical Safety
The compliance with all the electrical safety standards for any electronic ballast should be carefully verified.
All the required tests (such as dielectric strength, insulation resistance and contact current) are performed within AEC test laboratories, regardless of the insulation class and the power supply unit brand.

The final test, carried out on 100% of AEC products through an automated station located at the end of the line, is essential to assess the quality of the finished product.
This phase includes tests on functional insulations, luminous flux adjustment and data communication.
The basic functionality of the product is verified under different voltage levels in order to ensure the correct operation at any condition.
The device is properly positioned and locked on a vibrating plate that mechanically stress the luminaire in order to highlight eventual  troubles concerning the welding of electronic components.
Many other tests are performed during this phase: LED voltage and current measurement, evaluation of the power consumption, verification of the power factor.
All data are collected in a detailed test report and available for any future review.

Analysis of the electronic components reliability
Used tools: infrared thermo-camera, temperature data logger, reliability calculation software (prediction + FMEA / FMECA).
The  luminaire lifetime depends on the reliability of its components in the intended conditions of use. The evaluation of the electronic components reliability is carried out through the thermal analysis of components and through a mathematical calculation by means of a dedicated software.
According to the working conditions of each component (voltage, current, frequency, temperature) the MTBF value of the electronic device positioned inside the luminaire is estimated.
A further analysis of critical failures of each component (FMEA / FMECA) allows to accurately estimate the probability of devices failure.
