Historically, it has been easy. The colour output signal was BAD! Nobody enjoyed the boring, low-output blue colour of this ancient LED's. Well, that's changed and LEDs finally have a comparable light output and colour to that of low-wattage halogens we locate on our ships. Food photography lighting tips for frequently bought together with your ring light.
The problem nowadays is different. The marine environment using its various power resources is quite aggressive towards digital elements, particularly LED lighting. Voltage variations we see on our yachts would be the best enemy of LEDs.
I've promised to not get in the physics of powering LEDs, but allow me to try a few straightforward principles that are pertinent to LEDs. What follows does not need complex electronics knowledge, I'll call this section BOAT LED 101.
All LEDs are semiconductor diodes. They make their own light at the intersection of the negative and positive sides. When electricity is applied to a LED, the electrons jump from 1 side to another releasing mild in the kind of photons from the procedure. Various kinds of semiconductors create various wavelengths and consequently create different light colours.
The hot white lights which we favour in yachts are made by Indium Gallium Nitride (InGaN). Insert different substances, such as phosphors and you obtain a pleasant incandescent light shade
