The new EU standard luminaire standard EN60598-1:2015 will end the transition period and be enforced on October 20, 2017. This version has more technical revisions than the previous EN60598-1:2008, including some important technical changes. This includes new requirements for the construction of LED luminaires, more precise requirements for photobiosafety requirements, and insulation for different types of circuits. The biggest change is the inclusion of photobiosafety for the first time in mandatory standards. The new standard stipulates that if a luminaire including LEDs, metal halide lamps and some special tungsten halogen lamps that do not exempt the retinal hazard assessment source is used, it should be evaluated according to IEC/TR62778:2012 "Photobiosafety Blu-ray damage of light sources and luminaires". Application" for evaluation, and it is not appropriate to use a light source with a blue light hazard group greater than RG2. It is understood that blue light may have three effects on the human eye: first, excessive blue light content may cause increased visual fatigue; second, may have an impact on eye physiological development; third, long-term operation in such light environment, The possibility of inducing macular degeneration in the human eye is increased in old age. This time, the EU took the lead in raising the level of photobiological safety to the level of mandatory standards. It is expected that other countries and regions will gradually follow suit. Electric light source and related products of lamps are key export products of Shaoxing, involving more than 100 export production enterprises. The revision of the EU standard will greatly increase the production and testing costs of the enterprise; once the quality of the product does not meet the standard requirements, it will be subject to economic loss by the EU market and will be blacklisted. The Shaoxing Bureau reminds relevant enterprises to grasp the requirements of the new standards as soon as possible, especially the light bio-safety requirements first introduced; to grasp the quality control, to obtain a valid certification before export, to ensure that the quality of each batch of goods conforms to the importing country. Ask to avoid unnecessary losses.
Immersion Cooling is a technique used to cool components of IT equipment that consists of submerging the computer components in a thermally conductive and dielectric liquid. Through this practice, the servers are cooled and heat is transferred from the source to the liquid.

When we talk about Immersion Cooling, we also need to discuss the different types of Immersion Cooling, as well as the applications of Immersion cooling. The practice of Immersion Cooling has a multitude of benefits particularly as it allows datacenters to be managed in a greener and more sustainable manner. Environmental concerns has been a huge catalyst for the adoption of the technology in recent years.

Immersion Cooling systems used to have a higher fluid cost than water cooling, but this is already changing.
A wide variety of liquids exist for this purpose, the most suitable being transformer oils and other electrical cooling oils. Non-purpose oils, including cooking, motor and silicone oils, have been successfully used for cooling personal computers
