LED helps scientists discover the fluorescent communication of fish

In a recent study published in the Journal of the Public Library of Science (PLOS ONE) in early January this year, scientists used LED lights and used special filters on the lens to the Caribbean and the western Pacific. The fish was photographed. Because these filters are capable of simulating filters in the cornea of ​​fish, scientists have found that what is seen in fish eyes may be very different from what is seen in the eyes of the human eye or other species. The results of the shooting indicate that it is possible to see special fluorescent patterns on other fish in the eyes of fish.

The study found that 180 species of fish have bioluminescent patterns, which is more than people think. Many of the reef fish with protective colors have bioluminescent patterns such as squid, lizard, squid, squid, goby and halibut. Scientists believe that these fish may use bio-fluorescence for protective camouflage or to send information to other sources. If such bioluminescence can function as a means of transmitting information, this will provide a "private" communication signal for the fish, as the bioluminescent pattern may not be visible to the hunter.

As LCD display in YFJ company that we usually use it to military grade battery ,especially Lithium-ion batteries ,for these battery applications ,we have obvious advantage is that we focus more on shor circuit protection which we follow the US military standard.

Short circuit protection:The following test shall be performed. Charge batteriesas specified in  ; use of 4.6.3 is permitted. Measure and record the OCV. Short each battery across all the positive and negative terminals with a total external resistance not greater than 50 milliohms. After one hour remove the short from across the terminals. Measure and record the OCV. Stabilize batteries at the normal conditions of 4.3.1 for not less than 2 hours. Chargebatteries in accordance with 4.6; use of 4.6.3 is permitted. Stabilize batteries at normal conditions for not less than 2 hours, then discharge the battery in accordance with 4.7.2.3. The battery shall meet the requirements of 3.7.2.3.
