Exploring MEG pt.2: our Unique Lighting

4 likes

As you may already know, MEG's unique lighting properties have been designed and engeneered totally by us.

You can experience MEG light from just as low as 150£ / 250$ / 182€ per single PCB board, or buying the 4 PCBs bundle, or ending up buying the full kit.

This tech Update on the LED PCB will guide you through the light properties and hopefully will give Authority and Justification to our efforts.

In our next Update, coming in few days, we will cover MEG's Light Engine - so stay tuned!

1) GENERAL OVERVIEW

Lighting and oshw-minded product engineering is where we did our best, coming from Lighting and Industrial Design backgrounds.

Our design is meant to be the most effective for PAR (Photosynthetically Active Radiation) - in indoor-growing oriented plants of course. 

MEG’s Light Engine, which we designed from scratch, comes as a compromise between two things: “State-of-the-art Technology” and “Democracy”. 

Currently, first-class LED lighting for growing is expensive or hard to find - not talking of cheap crap you find on the Bay, but relating to professional gear for the mass growing industry.

Each PCB has 36 LED sources in this matrix:

#8 RED 630nm + #8 Deep-RED 670nm - on “R” Channel;

#4 Far-RED 730nm - on “FR” Channel;

#8 Deep-BLU 455nm - on “DB” Channel;

#4 BLU 485nm - on “B” Channel;

#2 Amber 595nm - on “A” Channel;

#2 Green 530nm - on “G” Channel.  

Here's some Spectrum samples that you'll have the power to control:

2) PCB ON-BOARD EQUIPMENT

All diodes are of the PowerLED category and are single-wavelenght emitters. The “RGB” term for us is taboo - makes us nervous. 

All LEDs are INCLUDED in the PCB. The PCB outline dimension is 20X20cm - 8X8in.

You may use MEG's PCB boards by driving them at 700mA. Some channels may be a bit over-drived, that's why our LED Driver may push up to 1000mA per Channel.

Another big value is the built-in Temperature Sensor; thanks to its sensing and connection to the Arduino controller, the output and board current-flow are atomatically regulated to avoid ovreheating - LED's worst enemy. 

Here's an outlook of the PCB Board: it's in white to further improve light diffusion:

 3) MEASURE OF SUCCESS

Our boards are designed by MEG's team. They're verified and manufactured under our in-person supervision

The spectral diagrams that you see in our documentation have been developed using Design/Testing iteration loops. 

We'd like to take this occasion to thank the "Laboratorio Luce" of Milan's Politecnico University to help and guide us through this process. 

We used a Konica-Minolta CL-500A Illuminance Spectrophotometer. Following please find some pictures of the development. 

Thank you for your attention - feel free to comment this Update! Love - MEG Team.
