Epidemic situation bring us some impact and thoughts

COVID-19 is a world war without fire. The virus that fell from the sky caused panic among people. Faced with this unexpected new coronary pneumonia, everyone’s life has been affected. We wear masks, run away from the crowd, can’t go out, can’t go to school, can’t meet with friends, many of us cannot help ourselves. The epidemic came suddenly this time, some people left and some recovered. Behind each number is the misfortune or luck of a family. The epidemic this time was sudden, terrifying, and panic, but to be precise, it was chaotic. After the outbreak, the harm has been obvious: this is the human tragedy that has hit the global economy the most since World War II. It soon overwhelmed the health systems of all countries, whether developed or developing countries are spared. The resulting society And the economic impact will be unprecedented. Especially in relatively poor and backward countries, this epidemic is undoubtedly worse, their health systems are weak, the supply of key medical supplies is in short supply, the economy lacks resilience and is heavily dependent on trade. They may soon fall into an ambush on all sides and encounter a health, economic, and social disaster that will affect the whole world. With the chaos brought about by the epidemic, it seems that people all over the world have stepped into an unknown water together, and the changes that emerge every day are testing how we respond and make adjustments. The world is facing huge challenges, and the epidemic will also bring mental stress to people. Fear and anxiety about new diseases and what might happen can be overwhelming and trigger strong emotions in adults and children. Some public health measures, such as maintaining social distance, can make people feel isolated and lonely, and increase stress and anxiety. stress during an infectious disease outbreak can sometimes cause the following: 1. Fear and worry about the health, financial situation or job of oneself and loved ones, or loss of support services on which they depend. 2.Changes in sleep or eating habits. 3. Difficulty falling asleep or concentrating. 4. Deteriorating chronic health problems. 5. Deterioration of mental health. 6. Increase the use of tobacco and/or alcohol and other drugs. The past “normal” suddenly disappeared. No one knows when this state will end? Or, what will it become next? From this incident. We have to start to examine ourselves. Regulatory action is a test of people’s awareness of self-control. All kinds of changes are taking place, and I hope everyone can make progress after experiencing this baptism of God to us. We live under the same beautiful sky, and we have the same heart that prays for beauty.

HUNTING FLASHLIGHT OF HIGH Cost-Effective SG-C8Q5

First of all, we must clarify a concept. Hunting activities must bring a flashlight, which is mainly used to search for prey after being hit and to illuminate the way home when it is dark. Prey hit, or used to search for potential prey. Animals are very sensitive to light sources. Very few mammals have phototaxis. If a light source suddenly appears in a dark natural environment, most animals will be frightened and will instinctively avoid them. I know that some hunting uses high-lumen headlights mounted on the roof of the car to illuminate the prey at night. The prey covered by the strong light may have disabling reactions. Small animals such as hedgehogs, rabbits and foxes are especially obvious, and they will stay still under strong light. Do not move or turn in circles, and then hunters can even catch prey with their hands. But this kind of behavior is firstly boring and not fun; secondly, it is strictly prohibited in some countries. Therefore, generally speaking, hunters will not use flashlights as a means or a way to assist in hunting animals, but only used to search for prey after being hit or to illuminate while traveling.   In Canada, the government almost does not allow night hunting, except in extreme cases. Some old hunters even go out without a flashlight because they find it troublesome. These old guns are very organized and don’t think about leaving the forest until dark, so they don’t use flashlights. In addition, I asked Mark, a veteran, and he said that when hunting for the past 20 years, how can there be the concept of EDC flashlight? The most common is the L-shaped military green torch. There are not many white light. After the battery is installed, the weight is amazing. Throwing it out can smash the bear. Therefore, when the older Orion wants to be a little lazy, first Throw aside the flashlight. So when they teach novices, they don’t know the content of hunting flashlights in detail. Today, the size, weight and brightness of the flashlight have been significantly changed. EDC flashlights with large palms can be bought at a price of about 300 yuan in the market. If you need to buy a flashlight suitable for hunting , Please follow the following principles. First, the volume cannot be very large. When hunting, the main purpose of our hunting suits is to cover up the smell of humans. There are not many pockets on the hunting suits, and the pockets and zippers are not always open. Therefore, the equipment to be used is basically on the belt, or In the backpack. Then, if you bring a large flashlight, such as the long strip police flashlight commonly seen in movies, the portability will be greatly reduced. I recommend choosing a flashlight that can be held together in one hand and does not exceed the length of your palm based on your palm. Of course, the headlamp style is also very convenient, but the neck will be more sore after wearing it for a long time. Different people have different opinions, I thin...

Diving flashlight of SG-D1 Diving series

When choosing a diving flashlight, many people will be fooled. On the surface, it is really good, but in fact, these are just the basic functions of diving flashlights. If these are not reached, then they cannot be called diving flashlights or diving flashlights. It is a necessary tool for diving, so when we choose a diving flashlight, we must not be fooled by the following major misunderstandings. brightness   Lumen is a physical unit describing luminous flux, and measuring the brightness of a flashlight is naturally no exception. How bright 1 lumens is, the expression is more complicated. In layman’s terms, a 40-watt ordinary incandescent bulb has a luminous efficiency of about 10 lumens per watt, so it can emit about 400 lumens of light. So when it comes to choosing a diving flashlight, how much lumen should we choose? This is a very broad question. The depth, purpose and technique of the dive are all factors in choosing the brightness. And the brightness can be divided into spotlight and astigmatism. Generally speaking, entry-level diving lights and flashlights with 700-1000 lumens can meet the basic needs. If it is night diving, deep diving, cave diving, etc., it needs to be brighter. 2000-5000 lumens is enough. More enthusiastic senior fans like 5000-10000 lumens, which is high-end demand, very bright, and can meet any purpose. waterproof   Waterproofing is the first guarantee of diving lights. Without waterproofing, it is not a diving product at all. The waterproofing of diving lights mainly involves the airtightness of the body and the switch structure. The diving lights on the market basically use ordinary silicone rubber rings. In a short time, it can achieve the waterproof function, but due to the poor elastic repair ability of the silicone rubber ring, it is susceptible to high and low temperature, and has poor resistance to acid and alkali corrosion. If it is used several times, it will lose its sealing effect if it is not replaced in time. Will cause water seepage. switch   Many flashlights that are claimed to be able to be used for diving always show off the so-called “magnet switch”. For “players” who play flashlights, this is a cool selling point. The magnetic switch, as the name suggests, is to use a magnet to change the size of the current through magnetism, open or close, but there is a very large instability of the magnet, the magnet itself will be corroded by seawater, and the magnetism will gradually weaken after a long time. , The sensitivity of the switch will also be reduced. At the same time, the most fatal weakness of the magnetic control switch is that it is easy to accumulate salt or sand in the sea water, which makes the switch unable to move, which leads to the failure of the switch. One more thing to note is that the earth itself is A larger magnet will produce a magnetic field, and the geomagnetic field will also have more or less influence on the magnetron switc...

Flashlight for hunting SG-C8T6 is worth your choice

Winter is a good season for hunting. Unlike in ancient times, hunting is for survival. Now hunting is a relaxing outdoor sport. The society is developing rapidly. Today’s hunting equipment is much more advanced than before, and it can capture prey more accurately. The essential tool for hunting now is the hunting flashlight. Hunting in some deep mountains and old forests, the trees are luxuriant and covered in layers, even in the daytime, the light is still not good, let alone some animals that come out at night and need to be hunted at night, then the LED flashlight for hunting needs Have the following characteristics. High brightness As for the specific brightness, at least T6 lamp beads should be used, and U4 lamp beads should be used if possible, with the highest brightness reaching 800-1000LM. Large battery capacity Because high brightness also means high power consumption, the large battery capacity also considers the battery life under high power consumption. To choose 18650 or 26650 lithium battery. Light color selection In a humid environment, it is best to use a warm color LED, that is, white 3000K. In a dry situation, it is best to use a white light LED, because white light is brighter than warm colors. In Europe, America and other countries, people also like to use red LED flashlights when hunting, because most animals are not sensitive to red light Gear selection There should be at least three gears, high, medium, and low. Some people don’t like 5 gears, because the flash function will frighten the prey and start the snake. However, it is impossible to prevent various accidents in the wild. Multiple flashes and SOS gears may save your life in a crisis situation. At most, you should not use this gear during hunting. Be waterproof Needless to say, waterproof, outdoor activities must at least ensure that it can be used normally under heavy rain and splashing, and it is best to meet the IPX-8 standard. Our SG-C8T6 can meet the above standards. This flashlight is more popular in Europe and America, and its switch is a tactical switch, so consumers don’t have to worry about the sound of the switch that will scare animals. And according to different scenes and animals’ sensitivity to color temperature, we can also change the color of the flashlight, such as red light or green light.

What are the advantages of 18650 battery or battery pack?

18650 is widely used in our lives. It can be used in notebook computers, walkie-talkies, portable DVDs, instrumentation, audio equipment, model aircraft, toys, video cameras, digital cameras and other electronic equipment. So what are the advantages of this battery?   Large capacity The capacity of 18650 lithium battery is generally between 1200mah~3600mah, and the general battery capacity is only about 800mah. If combined into a 18650 lithium battery pack, the 18650 lithium battery pack can easily exceed 5000mah.   Long life The 18650 lithium battery has a long service life, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries.   High safety performance 18650 lithium battery has high safety performance, non-explosive, non-combustible; non-toxic, non-polluting, and has passed RoHS trademark certification; various safety performances are integrated in one go, and the number of cycles is greater than 500; high temperature resistance performance, discharge efficiency of 100% under 65 degrees . In order to prevent the battery from short-circuiting, the positive and negative electrodes of the 18650 lithium battery are separated. Therefore, the short-circuit phenomenon may have been reduced to the extreme. A protective board can be installed to avoid overcharge and overdischarge of the battery, which can also extend the service life of the battery.   High voltage The voltage of 18650 lithium battery is generally 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries.   No memory effect, easy to use There is no memory effect. It is not necessary to empty the remaining power before charging.   Small internal resistance: The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. The internal resistance of domestic polymer batteries can even be below 35mΩ, which greatly reduces the self-consumption of the battery and extends the standby time of the mobile phone. The level of international integration. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and has become the most promising product to replace nickel-hydrogen batteries.   It can be combined in series or parallel to form a 18650 lithium battery pack   In addition, in order to fully utilize and protect the battery, 18650 lithium battery production requires a protection circuit to prevent the battery from being overcharged and causing discharge. Of course, this is necessary for lithium batteries. This is also a disadvantage of lithium batteries, because the materials used in lithium batteries are basically lithium cobalt oxide materials, and lithium cobalt oxide materials cannot discharge at high currents and are safer difference. Therefore, 18650 batteries have strict requirements compared to the general battery product...

Epidemic of COVID-19 has a very large impact on global life

A sudden outbreak of COVID-19 ,the epidemic has had a huge impact on global production and life. The online life at home has changed people’s habits of observing things, socializing, shopping, and reading. This change will be expected in the next few years. Keep showing up.   For us ordinary people, what is related to ourselves is not only personal health issues, but also needs to consider life and work all the time. This time the epidemic is so severe that some companies will definitely not be able to sustain it and their revenue will also be affected. People who work from home may be more or less anxious about being unemployed. Although they are working from home, they are no less stressful than working in a company. In this case, it is a test for the company, and it is actually a problem for everyone. In the test, if there is no good output, the leader may not say anything, but he will definitely give each employee a score in his heart.   Some companies with relatively large impacts may lay off employees or even close down, and this phenomenon is not an exception. As the impact of the epidemic becomes more and more serious, this phenomenon is also increasing. This has brought a lot of worry and anxiety to ordinary people. Some people want to change jobs, but because of the current situation, they will choose to continue their current work. They also choose to make concessions out of uncertainty about the current situation. The epidemic has had a very large impact on individuals and the global economy. This situation not only affects existing occupations, but also disrupts education and training arrangements, creating a huge obstacle for groups eager to enter the labor market or change jobs.   But we must be firm in our conviction and believe that the epidemic will be overcome, because only in this way can society be able to return to normal production. In human history, we have experienced many global crises together: three major flus in the 20th century, financial crisis in 2008, H1N1 flu in 2009… What lessons should we learn to fight the new crown epidemic? Viruses know no borders, and epidemics do not distinguish between races. We can only believe in science and unity.

The headlights responsible for active lighting must illuminate the road conditions ahead. And the taillight which belongs to the passive lighting, shoulders the responsibility that lets the car friend be other people, the car see. Tip 2: USB or battery charge? Consumers can decide to buy the battery type taillight or the USB charging taillight according to their cycling habits and the product features mentioned above. For example, it is rare for people who ride at night, because the use frequency of taillights is low, so it is more economical to buy battery taillights. As to taillight use frequency high, but do not need the car friend of overlong endurance, suit to buy USB to charge taillight.

Night riding: cherish life, please install bike safety light

The bike safety light is a good reminder for your life when you ride and run at night. Nowadays, due to the rapid development of of society and the accelerated pace of life, people seldom have time to exercise during the day. Therefore, more and more people like to keep themselves healthy by riding and running at night. But do you know? If you don’t use the bike safety lights for night riding and night running, you may be putting yourself or someone else at risk. Because if there are no bike safety light, many bicycle paths are dark without streetlights, which can be dangerous and make you fall or hit others. Not long ago, there was a traffic accident in yichun, jiangxi province. A women who was running in the night was hit by a bicycle and she died on the spot. Sadly, neither of them had installed any bike safety light or worn headlights while exercising. If the bike had been equipped with a bike safety light, would the result have been different? All in all, installing a bike safety light during night riding is a lamp that illuminates the path of yourself and others.

Ten taboos for cycling safety (1)

As more and more people participate in the cycling sport, many newcomers also have such bad habits. The bad habits in these rides have great hidden dangers to the traffic safety of the riders. 1. The wrong way up and down the slope Some people stand up and pedal when riding an uphill section. But unless it is a particularly steep slope or needs to accelerate the sprint, this position should be avoided. In addition to being more physically demanding, the riding center of gravity increases the handling and the rear wheels are also prone to slip. The correct way should be: when going uphill, sitting forward, lowering the upper body to keep the center of gravity, and stepping on with light teeth. When going downhill, the body’s center of gravity moves backwards, the body is depressed, and the thighs grip the cushion. Pay attention to the control speed, the method of progressive braking should be adopted, and emergency braking is strictly forbidden to ensure safe driving. 2. Improper turning methods The body will tilt when cornering, and the inner pedal should be kept horizontal or top to avoid touching the ground. It is necessary to slow down before entering the corner. It is very dangerous to brake during the turn. 3. The safety distance is not enough If you follow the team for group cycling, you should always maintain a safe distance between vehicles. In the long-distance ride, the car will be shielded from the wind for easy cycling. When the road is wide and straight, it is easier for the rider to scatter. It is recommended that the rider be separated by at least one bicycle for safety.

Do you know how to choose a bike light?

For people who like to ride, the bike light is a necessary thing for cycling. However, do you know how to choose a bike light? To choose suitable bike lights, we need to know the lumen first. Lumen is a units of light, and we need to know, the higher the lumen value, the brighter the light. But there are a mistake in most of people, the brighter the light, the better the bike lights, this is absolutely wrong. Your bike light is used for Brightening the front, but you should also consider whether the other side of the car is glaring. It is a safe choice to distinguish each other position. The requirement of bike light is a good floodlight, the spot must be larger, not require a long distance, but brighten a large spare, and there must be a clear cut-off line to avoid interfering  the incoming car.   The another requirement of the bike lights is a high seismic performance, because the bicycle may encounter uneven roads and bumps. If the seismic performance is bad, the gear suddenly jumps and the lights are extinguished, which is very dangerous.   What’s more, the lights that are riding at night must have a certain function of waterproof. When we riding, it’s often raining, if you riding in raining without a bike light,it’ll be a hidden danger.
