Led Panel Tech:" Cabriolet " or no ?

Wouldn't that depend upon the lens angle ?

If using a wider lens having them closely packed together wouldn't be that crucial in blending the spectrum....now if using a more narrow
lens having them laid out closely would be more crucial to achieve a blended spectrum.

• To cover or no ?
  
  I mean ....
  
  Should the leds be covered with some kind of thin polymer screen -mainly for protection - or no ?
  Hmmm ....

For DIY, it is IMAO a good thing to cover around the led and every solder points (for protection against corrosion and for insulation) with an acrylic coating. If you spray it, you will cover the lens, and you will loose at least 5% of flux. It can be easily done by hand with small brush, and it is cheap to buy a little spray bottle. Spray the liquid coating into a small bowl and take it with a brush.

The acrylic coating will protect the connections, and will strengthen the assembly. For example ACC11 works well, and it dries very fast. Clean the brush with acetone.

Transparent/blue protection and coating varnish for PCBs, coils and other components, does not have to be removed for soldering. Resistant to frequencies and voltage (inherent resistance 22 kV at a layer thickness of 25 µ), does not drip, even distribution, resistant to acid, salt water and condensation, temperature-proof from –30 to +142 °C.
