LED cooling technology and cooling materials

LED cooling technology and cooling materials

Heat dissipation is a major factor affecting the intensity of LED lighting. Heat sink can solve the problem of heat dissipation of low illumination LED lamps. A heat sink can not solve the 75W or 100W LED lighting cooling problem.
In order to achieve the desired illumination intensity, active cooling technology must be used to solve the heat by LED lamp assembly. Some active cooling solutions as LED lamps. In order to provide a practical active cooling solution for high brightness LED lamps, the heat dissipation technology must be low energy consumption; and can be applied to small lamps; its life is similar to or higher than the light source.

 

Cooling method

Generally speaking, in accordance with the way from the radiator to take away the heat, the radiator can be divided into active cooling and passive cooling. The so-called passive heat, is through the heat sink of heat source LED light source naturally distributed to the air, the cooling effect is proportional to the size of the heat sink, the effect of course greatly reduced heat , often used in the space of the heat dissipation, such as some popular motherboards in the North Bridge also take a passive cooling, the vast majority of take the initiative to heat, active cooling is through the fan and other cooling equipment forced The heat will be out of the heat sink, which is characterized by high thermal efficiency, and equipment, small size.

Active cooling, subdivided from the way heat can be divided into air-cooled heat, cooling heat, heat pipe cooling, semiconductor refrigeration, chemical refrigeration and so on.

Air-cooled air cooling is the most common way of cooling, in comparison, is also cheaper way. Air cooling is essentially a fan that takes away the heat absorbed by the radiator. With the price is relatively low, easy installation and so on. But the environmental dependence is relatively high, as the temperature rise and overclocking its thermal performance will be greatly affected.

Liquid cool

Liquid cooling heat is driven by the liquid in the pump driven by the heat to take away the radiator, compared with the air-cooled, with a quiet, cooling stability, the advantages of small dependence on the environment and so on. The price of liquid cooling is relatively high, and the installation is also relatively cumbersome. At the same time as installed in instructions to install the instructions in order to get the best cooling effect. For cost and ease of use considerations, liquid cooling is commonly used as a heat-conducting liquid, so liquid-cooled radiators are often referred to as water-cooled radiators.

Heat pipe

The heat pipe is a kind of heat transfer element which makes full use of the heat conduction principle and the rapid heat transfer property of the refrigerant. It conveys heat by evaporation and condensation of the liquid in the fully enclosed vacuum tube, has extremely high thermal conductivity, good isothermal The heat transfer area on both sides of the hot and cold can be arbitrarily changed, can be a long distance heat transfer, can control the temperature and a series of advantages, and heat pipe composed of heat exchanger with high heat transfer efficiency, compact structure, advantage. Its thermal conductivity has far exceeded the thermal conductivity of any known metal.

Semiconductor refrigeration

Semiconductor refrigeration is the use of a special semiconductor cooling film in the electricity generated as the high temperature side of the heat can be also distributed, the low temperature side is constantly cooling. A temperature difference is generated on each part of the semiconductor particles, and a cooling sheet is formed by the concatenating dozens of such particles as the form of temperature difference on both surfaces of the cooling sheet. The use of this temperature phenomenon, with the air-cooled / water-cooled high-temperature side of the cooling, can get excellent cooling effect. Semiconductor cooling has the advantages of low cooling temperature and high reliability. The cold surface temperature can reach below 10, but the cost is too high, and the process of semiconductor refrigeration is not mature enough practical.

Chemical refrigeration

The so-called chemical refrigeration, the use of some ultra-low temperature chemical substances, the use of them in the melting time to absorb a lot of heat to reduce the temperature. It is more common to use dry ice and liquid nitrogen. Such as the use of dry ice can be reduced to below 20? temperature, there are some more ‘abnormal’ player

Nazi-era art dealer’s treasure trove debuts in Europe

Nazi-era art dealer’s treasure trove debuts in Europe

It’s an art collection like no other because it’s collected like no other.

Hundreds of pieces of art are now on display from a spectacular stash that was once hoarded by the son of a Nazi-era dealer. The artworks, including masterpieces by Monet and Rodin, are being shown for the first time since World War II this year as part of parallel exhibitions in Switzerland and Germany.

All of the exhibits were seized by the Nazis during World War II in a methodical program directed by German dealer Hildebrand Gurlitt. He led the task of poaching art from Jewish families and selling art defamed as “degenerate” overseas.

It’s a display that now sheds light on the darkest chapters of Nazi Germany, says art director Nina Zimmer.

“How they persecuted artists and art they did not like and how they did this systematically,” Zimmer says.

The works may never have been stumbled upon during a routine tax investigation at a nondescript address in Munich.

Hildebrand’s reclusive son, Cornelius Gurlitt, had hidden away a trove. The priceless Rodin sitting near a potted plant and the monet hanging on a wall.

The Rodin found in Munich
The exhibition has raised morale and ethical issues over the art’s true provenance and inspections.

Project director Andrea Baresel-Brand says that the shows can act as something of a lost and found.

“Through the broad media coverage of the exhibitions of course a wider public is reached and maybe somebody recognizes something,” Baresel-Brand says.

Even conservative estimates of the collections have been reunited with their rightful owners.

Enchanted Village of Morzine Casts a Spell for Kids

Christmas is a magical time of the year, but I also know just how stressful it can be for parents – this is especially true for those with a boisterous brood! This Xmas, why not whisk the whole family off for an unforgettable vacation? This can take a great deal of pressure off the family occasion, whilst treating the little ones to plenty of adventurous fun.
Morzine is a wonderful place to spend Christmas with its two-week festival over the holi-days called “The Enchanted Village of Morzine”. A lovely and festive atmosphere sweeps across the child-friendly resort, and there are lots of great facilities and activities for kids.

 

In the unlikely event that they tire of the festival and skiing opportunities, kids can also enjoy sledding, ice skating, swimming, husky sledding and more. There is plenty for mum and dad to experience here too! Another key selling point? A quick and easy journey to get there: fly into Geneva and then jump into a pre-booked Geneva to Morzine transfer.

Check out the schedule for the brilliant two-week festival:

Illuminations – To get everybody in the festive mood, the entire Tourist Office Square is decorated with stunning illuminated decorations. This looks fantastic against the white of the snow lit up beneath the starry night sky.

Father Christmas – What is Christmas without a visit from jolly Old Saint Nick!? The little ones will be thrilled to see Santa arrive in the village with plenty of joy and gifts in tow.

Workshops – Keeping children happy and entertained can be challenging over the holidays, but not here. There are dozens of workshops to keep them busy and this is also a great way for them to make new friends. Card making, garland- and druid-making work-shops are just a few options.

Ice Sculpture – Professional ice sculptor Sebastien Cohendet is in town and watching him turn a block of ice into a piece of art is an experience that is sure to dazzle the entire family.

Fireworks – Get ready for plenty of “ooohs” and “ahhs” with Morzine’s very own fireworks displays. In the snowy mountains, this is a unique experience and even more magical than the displays you get back home.

Children’s Cookery Classes – Another great way to keep your brood busy, the children’s cooking classes will teach them how to make a range of tasty treats in a fun and safe environment. Who knows, they may enjoy it so much that they offer to cook back at home!

Street Theatre – No Christmas is complete without theatrics. Watch the superb and highly amusing street theatre parades put on over the course of the festival. These really un-ite the village and get everybody in the mood for an unforgettable Christmas.

Entry to the festival is free too, so you can benefit from all this excitement without break-ing the bank! Now that is good value for money.

Concrete brings us a brand new Japanese watering hole and dining experience at Izakaya in Hotel Roomers, Munich.
Hotel Roomers in Munich stands out for its Japanese restaurant, Izakaya in an incredibly unique way. The restaurant announces its presence via its show kitchen visible through the glass facade of the porte-cochere. This kitchen block continues inside the lobby as a jewellery case covered in gold mirror – also the restaurant’s main entrance!

 

Black and gold dominate the colour palette here with a contrasting feature of light wooden lamellas along the ceiling and wall. Gold cladding uplifts the space especially through the backlit bar top, with a warm yellow marble finish that makes every drink sparkle. While the bar is a highlight element, one cannot miss the show-stopper i.e. the oversized wooden Koi-carp lamp. Typically Japanese, this lamp would’ve probably overpowered the design had it not been so dynamic!

Seating zones are created by introducing silk-printed rotating panels that are also black mirrors and level changers. The rotating panels serve many purposes: they can either connect or separate the space depending on the angle of rotation. While on one side, a Japanese-inspired artwork on silkscreen by artist Gijs Scholten anoints it; the other side is clad with a black mirror with different settings. In the early evening, the whole space can appear as one; while during the after-hours, the bar can be cordoned off to establish a darker and cosy mood that lasts deep into the night. This element helps the space adapt to its clients allowing for a truly transformable experience.

Wake Up Feeling Well Rested with this Pregnancy Sleep Tips

Wake Up Feeling Well Rested with this Pregnancy Sleep Tips

In the midst of the excitement of finding you pregnant comes the fact that life will never be the same again. And as you embark on this epic journey, take note; sleep will be a very valuable commodity!

And we are not just talking about after the baby is born. As your baby grows, you may find it increasingly difficult to feel comfortable at night.

Here are some tips to help you sleep well.

Drink Up, Then Go Down

Disturbed sleep when you are pregnant is caused by many factors, including anxiety, hormones, physical discomfort and, most commonly, a constant urge to go to the bathroom.

While it is important to drink lots of fluids every day, it’s good to drink less during the day and evening.

Your body is worried so filling it with caffeine and spicy food will only make things worse. Limit tea, coffee, chocolate, and soft drinks just one or two days, and only in the morning.

Pay attention to the spicy food

Pregnancy alters your entire metabolism so that while you can eat chili, curry, and other spicy dishes with no side effects, you may have to let go for a while.

Pregnancy can make you very susceptible to indigestion and heartburn. If so, try eating a snack, and allow yourself two to three hours of digestion before bed.

Stick To A Routine

We know, you hate routines, but when pregnant, it can cause a good night’s sleep. It will also prepare you after the baby is born.

Design your routine that is soothing and relaxing before you sleep. This includes a warm bath, enjoying a decaf warm drink, reading a book, or getting a massage.

Move

Discuss the sports regime that suits your doctor. It’s good for you and your baby to keep moving, to improve circulation, maintain a good weight and avoid night cramps that keep you awake.

But do not be late during the day. While exercise releases endorphins that make you feel good, it also releases adrenaline, which can damage deep sleep.

Get Pregnancy Pillow

One of the biggest sleep problems when you are pregnant can not find a comfortable position. Because there is a big baby bump in the road!

Sleeping on your stomach will be increasingly uncomfortable, and many mothers worry they will destroy their baby.

Sleeping on your back is not recommended, as it puts pressure on your organs, and on one of the main body’s veins. And even if you start by your side, the habit tends to force you back into your normal sleeping position.

Rest comfortably

Fortunately, there is now a way you can sleep comfortably in your stomach, throughout your pregnancy, without harming the baby. And it’s a pregnancy pillow.

Pregnancy pillows are a big step forward from old style maternity pillows, for comfort, safety, and practicality. This is the perfect way to ensure a good night’s sleep or a refreshing afternoon nap.
