🏠︎ / Produkty / Linear LED Modules / D2W AD2820L28 1ft 500 lm

Detailed description

The AD2820L28 linear LED module introduces the functionality of dynamic colour change correlated with brightness levels.

The D2W (Dim To Warm) mechanism mimics the behaviour of traditional light sources, warming the colour when the supply current is reduced.

The design has been optimised for LEDiL DAISY-MINI lenses, allowing for precise light distribution in modern office lighting systems.

The device operates in the SELV standard, which means a safe operating voltage below 60 V.

The use of high-quality components on a rigid PCB laminate guarantees an L70B50 lifetime of over 72,000 hours.

Polish production at the ALSC plant ensures colour consistency and full control over the technological process.

The ability to mix colour temperatures in a single MOQ makes it easier for us to manage production.
Dedicated LED modules arrive efficiently, and adequate stock levels at ALSC prevent downtime during assembly. This is a concrete collaboration that allows us to maintain full process continuity.

Tomasz Lipka

Production Director at BEMKO GROUP

The use of wide-angle optics modules from ALSC allowed us to achieve perfectly even illumination across the entire surface of the luminaire and optimise production costs. The company manufactures modules according to individual designs, which in our case allowed us to embark on a new project.

I recommend working with ALSC.

Piotr Jedynak

Head of Production at BD-LUX Sp. z o.o.

We have been working with ALSC for 5 years. The company has supplied us with advanced LED modules for research and development projects.
For me, it is the best company of its kind in Europe.
The solutions proposed by ALSC often exceed our requirements, paving the way for true innovation in the technology we deal with at Nanosci.

Adam Kądziela

CEO&CO-FOUNDER at Nanosci Sp. z o.o.

Working with ALSC proved to be the right choice.

For our space project, we were looking for a company that could produce specific lighting modules with a solar colour.

We are very pleased that we were able to develop a solution that proved successful both in our experiment on the International Space Station and in the algae cultivation laboratory. A highly personalised approach to the customer and the ability to tailor lighting modules to specific needs.

We hope to continue our cooperation! I highly recommend them!

Why is the A5616L8 LED module a better and cheaper alternative to ready-made LED panels and ceiling lights?

The A5616L8 1100lm LED module is the key to optimising the cost of your luminaire. It is a much cheaper alternative, offering savings of up to 50% compared to ready-made LED panels and ceiling lights. We guarantee its versatility thanks to the possibility of precise cutting every 70mm. In addition, this dedicated LED module provides high efficiency of up to 191 lm/W (for CRI80).

Where and under what conditions do you manufacture LED modules, and do you have your own technical facilities?

ALSC is a Polish manufacturer of LED modules and has its own SMT and THT assembly line. A specialised measurement laboratory ensures control over every stage of the process. It is there, in the integrating sphere, that we verify key optical parameters: luminous flux (lumens), CCT, CRI and McAdam SDCM.

Does the OEM service only apply to your own designs, or can you create an LED module from scratch?

The OEM service applies to both scenarios. As ALSC – a Polish manufacturer of LED modules with our own design office and SMT/THT assembly line – we can adapt our wide range of proprietary light sources, but also create a completely new LED module from scratch at the customer's request.
