Advanced LED Lightbulb Made from Salmon DNA

Biological materials have often proved that are very efficient in various technological processes, and when they were used was even observed an increase in the obtained product efficiency. Same thing happened at the University of Connecticut, where researchers have managed to create a LED lightbulb from salmon DNA, adding fluorescent dye to salmon DNA, they bring to life a new material with a bright white light shade.
The technologic basic principle consist in a LED light coated with salmon DNA nanofibers. “The DNA fibers orient the dyes in an optimum way for efficient [fluorescence energy transfer] to occur.”, as researchers say. This LED lightbulb proved to be more effective than other LEDs created until now by other researchers,LEDs with colored lights and with different intensity. The salmon DNA LED lightbulb make the transition from cold white to warm white,the light shade is perfect,it has a proper light intensity, solving all LED light quality problems encountered until now.
The only problem that researchers have not taken it into account is the price that could be higher compared to previous LED’s. Also researchers still not knowing if these LED lightbulb are more energy-efficient than previous LEDs. If these two issues could be resolved, the salmon DNA LED lightbulb might be the cheapest and most efficient product in its category.
