How to test the lamps, the lamps test standard

1.Marking of lamps

When inspection lamps and lanterns should check the mark on lamps and lanterns above all, wait like trademark, model, rated voltage, rated power, judge whether its accord with the use specification of the masses. Marking safety is the basic requirement in the safety performance of lamps and lanterns, among which rated power is particularly important. For example, if a lamp is designed to be 40w, without marking rated power, users are likely to install 60w or 100w bulbs, which may cause shell deformation, insulation damage, even electric shock, and possibly cause fire.

Additional, standard stipulates, the wire minimum cross section that USES on lamps and lanterns is 0.5 square millimeter, some manufacturer is to reduce cost, the traverse sectional area that USES on the product is less than 0.5 square millimeter, make electric wire scorch possibly so, short circuit happens after insulator layer burns out, produce danger. During the inspection, you can see the marks printed on the insulating layer outside the wire on the lamp.

2.Protection against electric shock

Should pay attention to the protection against electric shock, after the lamp is energized, the person should touch the live parts, there is no danger of electric shock. If be incandescent lamps and lanterns (for example droplight, wall lamp), install bulb to go up below the circumstance that is not electrified, if touch with little finger cannot live part, prevent electric shock performance is basically accord with.

The antishock performance of lamps and lanterns does not meet the standard, it is to use the lamp holder that does not meet the requirements or the live parts of lamps and lanterns do not add cover to prevent electric shock protection measures caused by.

3. identification from the structure of the luminaire

There should be no sharp edge at the entrance and exit of the metal pipe after the wire, so as not to cut the wire, resulting in electrification of the metal parts, the risk of electric shock. Table lamp, floor lamp and other movable lamps in the power line entrance should be wire fixator, its role is to prevent the power line push back to hit the heating element, wire overheating caused by melting insulation layer, exposed wire and metal shell contact, shell electrification and lead to electric shock.

4. identification from the accessories used on the luminaire

(1) If the lamps and lanterns with electronic ballast, should choose and buy with abnormal protection of electronic ballast lamps, the so-called abnormal protection refers to the fluorescent line when there is an abnormal state of protection, so that the electronic ballast can still work normally.

(2) Lamps such as the use of inductive ballast, look at the ballast on the logo, try to choose the Tw value of a higher (such as Tw130) especially lamps and lanterns cooling conditions poor, should pay attention to this point. Tw is the rated maximum operating temperature of the ballast coil, at which the ballast can operate continuously for 10 years.

The WHO says a COVID-19 vaccine could be developed by the end of the year

On June 18 local time, WHO chief scientist Sumiya Swaminathan said that at least 200 COVID-19 vaccines are under development and about 10 have entered human trials. Three of them will soon enter phase III clinical trials, including one from China.

Sumiya Swaminathan notes that China has several vaccine candidates, and the results of phase I and II clinical trials show promise.

Sumiya Swaminathan also says one or two successful vaccine candidates could be available by the end of the year. The goal is to have 2 billion doses of vaccine produced by 2021. Fortunately, novel Coronavirus appears to have far fewer mutations than influenza viruses, and the mutations that lead to such critical parts as disease severity and immune response have not yet been shown.

Basic knowledge of eyewear inspection

Type of Eyeglasses

A. Classification according to the materials of spectacle frames: plastic frames, metal frames and mixing frames.

B. Classification according to lens materials: glass lenses, resin lenses, plastic lenses.

C. Classification according to the style of glasses: full frame, half frame, no frame, combination frame and folding frame.

D. Classification according to the use of glasses: myopia glasses, flat glasses, sunglasses, diving glasses and reading glasses.

Check your glasses

1. Frame size (emphasis)

2. Check whether the parts of the glasses are missing. (frame, pile head, mirror foot, foot cover, hinge, lock block, screw, nose rest)

3. Check whether the screws are too tight or too loose. (at the bridge cover/foot/frame)

4. Check if the earhooks are too tight or too loose.

5. Check the frames and frames for scratches, cracks and stains.

6. Check the assembly of glasses for errors.

7. Check whether the lens is firm.

8. Check whether the LOGO printing is clear and there is no double image.

9. Check the lens for scratches, damages, stains and cracks.

10, check the frame material, there is no defect, whether easy to break.

11. Check whether the surface is painted evenly and the color is bright.

12. Check whether the bridge sleeve has any unrepaired corners.

13. Check whether the hooks on both sides are symmetrical and smooth. (it is better to choose a flat and clean place, open the glasses and place them horizontally to check whether the height of the hooks on both sides is the same and whether the structure is symmetrical.)

Analysis of the advantages and disadvantages of the major manufacturing powers

Analysis of the advantages and disadvantages of the major manufacturing powers

The United States has the world’s second largest manufacturing industry. In 2016, the added value of the manufacturing industry was close to US $ 2 trillion, accounting for about 16% of global manufacturing value added and 12% of US gross domestic product. The United States is the eighth complex economy in the world. However, in the past 20 years, the competitiveness of American-made products has declined and its attractiveness as a manufacturing destination has faced severe challenges. The United States has an advantageous position in shaping the future competition of the manufacturing industry, and has achieved the highest weighted score for manufacturing drivers. It ranks among the top five in terms of driving factors other than sustainable resources and the institutional framework.

The United States is also world-renowned for its innovation capabilities and has a place in the forefront of major developments in emerging technologies in the Fourth Industrial Revolution. In addition, outstanding higher education institutions support the development, attraction, and retention of advanced human resources in the United States. It is worth noting that the United States is currently working to revive manufacturing. In the tax reform at the end of 2017, the United States reduced the corporate tax rate from 35% to 21%, which increased the willingness of enterprises to transfer some production to the United States.

However, policy and regulatory uncertainties related to immigration and free trade agreements remain. As one of the world’s largest carbon emitters, the United States needs to prioritize energy efficiency and sustainability issues.

Japan

At present, Japan has the third largest manufacturing industry in the world. The total value added of manufacturing industry in 2016 exceeded US $ 1 trillion, accounting for nearly 9% of the global manufacturing value added. China, the United States and Japan together account for nearly half of the global manufacturing added value.

Japan has been the most complex economy in the world since 1984. In terms of manufacturing drivers, Japan is particularly prominent in the demand environment, with a mature consumer base, strong corporate activity, and a huge market size. Japan ranks in the top 20 in terms of technological innovation and institutional framework. In 2016, the Japanese government launched the “Social 5.0” strategy, which aims to promote the transformation of manufacturing through emerging technologies, and even achieve social change.

In addition, the Japanese government also proposed a “Connected Industries” plan in 2017 to support industries such as Japanese manufacturing to create new value through the connection of resources, people, technology, organizations, and other social elements.

The challenges facing Japan are mainly related to human capital, including aging populations, shrinking populations, and lower numbers of immigrants than comparable countries. In addition, Japan has room for improvement in terms of sustainable resource drivers.

Analysis of the advantages and disadvantages of the major manufacturing powers

Germany

Germany has the fourth largest manufacturing industry in the world. In 2016, the total value added of the manufacturing industry reached US $ 775 billion, and its economic complexity ranked third in the world. Germany has a world-renowned tradition of high-quality manufacturing, and more than half of its manufacturing output is exported overseas. Germany ranks first among comprehensive manufacturing drivers and top ten in technology and innovation, human capital, global trade and investment, and demand environment drivers. German educational achievements are outstanding, technical training programs are leading, the quality of the workforce is high, and the ability to innovate is strong.

With the launch of the “Industry 4.0” plan in 2011, Germany is committed to the digitization and interconnection of products, value chains and business models, and vigorously promotes the development of digital manufacturing, becoming one of the leading countries in this field. Globally recognized as one of the pioneers of the Fourth Industrial Revolution, Germany has played a leading role in setting new global industrial standards and regulations.

India

India is the fifth largest manufacturing country in the world. In 2016, the total value added of manufacturing reached US $ 420 billion, ranking 45th in economic complexity. Over the past 30 years, Indian manufacturing has grown at an average annual rate of more than 7%, with average output value accounting for 16% to 20% of GDP. India is the second most populous country in the world and one of the fastest growing economies in the world. The market demand for Indian industrial products is on the rise.

In addition to the top five demand environments, India has plenty of room for improvement in other manufacturing drivers. Human capital and sustainable resources are two key challenges facing India. India’s labor force is relatively young and growing rapidly, but the quality of the labor force needs to be further improved. India should pay attention to measures such as upgrading education courses, improving vocational training programs, and enhancing the digital skills of the workforce.

In addition, as manufacturing continues to expand, India also needs to continue to expand access to energy and reduce emissions. In 2014, the Indian government launched the “Made in India” program, with the main goal of making India a global manufacturing center.

Korea

Over the past few decades, South Korea has experienced significant economic growth, from a backward agricultural society in the 1960s to a manufacturing powerhouse today. South Korea currently has the sixth largest manufacturing industry in the world. In 2016, the total value added of the manufacturing industry exceeded US $ 380 billion, and its economic complexity ranked fourth globally. In addition to its poor performance in sustainable resources, South Korea has generally performed well on other manufacturing drivers.

South Korea is particularly strong in terms of technology and innovation, ranking among the top five in terms of R & D expenditure and patent applications per million people. The outstanding innovation ability has contributed to the historic rise of South Korea and will also help South Korea lead the development of the next generation of production models. In order to strengthen its preparations for shaping the future of manufacturing, South Korea needs to continue to improve its workforce, especially in developing critical thinking skills, digital skills, and advocating knowledge-intensive employment.

In addition, building a sound, transparent, and credible organization can help guide South Korea’s vision for the future of manufacturing and build the trust needed for global connectivity.

Made in Vietnam is not to be underestimated

In 2012, the last factory of adidas in mainland China was closed in suzhou.

In 2009, Nike Vietnam OEM completed the full capacity of China.

Today, Nike and adidas produce 50% in Vietnam and 20% in China.

In April 2018, uniqlo announced a shift of capacity from China to southeast Asia, with Vietnam responsible for 40 percent of total production.

Benefiting from the shift in the industry chain, Vietnam’s footwear exports reached $18 billion in 2017, making it the world’s second-largest footwear exporter after China.

Not only foreign brands, attracted by cheap labor, many shoe and cap apparel companies originally rooted in China’s guangdong and fujian provinces set off a wave of factory relocation to Vietnam.

Nanxuan, a Chinese apparel company that makes sweaters and other knitwear, will expand production in Vietnam. Nanxuan, based in huizhou, guangdong province, built a factory and started production outside ho chi minh city in 2015.

Bosideng, a Chinese manufacturer and seller of down jackets, is also expanding production in southeast Asia.

With the help of its capital partnership with itochu of Japan, bosiden has begun pilot production at a Vietnamese textile plant linked to itochu, with plans to expand further depending on production trends.

The reason for the transfer is not complicated, because labor costs to Vietnam can be nearly 60 percent cheaper.

It is not just China’s low-end industries that Vietnam is taking on.

In May 2018, samsung and Olympus closed their factories in shenzhen and moved to Vietnam.

Some media outlets even thought that the Japanese and Korean electronics industries were losing out in China, lamenting that they “saw the building collapse”, but did not know that samsung had invested $15 billion to build an unprecedented manufacturing base in the Saigon high-tech park.

Shut down factories in China as soon as the production lines are up and the staff are trained.

Microsoft moved nokia’s Beijing plant to Hanoi.

Intel is spending more than $1 billion on a high-tech park in Saigon, where it plans to deploy 80% of its global chip production.

Vietnam is trying to become a new manufacturing hub for the global electronics industry.

In 2017, Vietnam exported $45 billion worth of mobile phones, and a tenth of the world’s smartphones were made in the southeast Asian country.

And mobile phones have become the number one product made in Vietnam.

We often feel that we are the world’s no.1 in the whole industry chain, and the skilled workers are endowed with unique advantages. However, we forget that this is only a matter of a decade or more, and it is no worse than a decade for others. In addition, the population and industrial structure of southeast Asia have undergone great changes.

Of course, Vietnam is not without its shortcomings. Its industrial structure and population quality still lag behind that of China. However, with the deepening of trade frictions and the passage of time, the future is uncertain.

Vietnam alone accounts for nearly 10% of China’s exports, enough for the whole of southeast Asia plus India.

Analysis of Myanmar’s investment environment

Myanmar’s economy has developed rapidly in recent years, with GDP growth rate remaining at around 7%. Driven by investment represented by infrastructure, domestic demand has become the main driving force for Myanmar’s economic growth, and rapid export growth has also been another boost to Myanmar’s economic growth. The ongoing reform of business legislation is helping to optimize the domestic investment environment. Foreign investment in Myanmar’s manufacturing industry still maintains a strong momentum. The economic growth prospects are promising. It is expected that the economic growth rate will be around 7.2% in the next few years.

In order to attract foreign investment, Myanmar has developed a Myanmar investment plan with the help of the Japan International Cooperation Agency. In the next 20 years, the amount of investment into Myanmar is expected to reach 200 billion US dollars.

In the 2018-2019 fiscal year, foreign investment reached 4.2 billion U.S. dollars. However, the Rakhine State terrorist attack, some Western investment companies misunderstood Myanmar, so investor confidence was hit to a certain extent, and investment projects were delayed. If foreign companies apply for offshore oil blocks and mining exploration projects, the amount of foreign investment into Myanmar is expected to be a record.

Data show that from 1988 to the end of September 2019, a total of 50 countries and regions have invested in 12 economic sectors in Myanmar, with a total of 1,837 projects invested. The largest investments in Myanmar were made in Singapore and Thailand. The largest investment was in the oil and gas sector, with 27.38% of the investment; 25.87% in the power sector; and 14.08% in the industrial production sector.

After the NLD government came to power, it emphasized economically to attract foreign investment and allowed a wide range of foreign investment. Myanmar’s foreign investment is subject to national treatment. According to Myanmar’s new Investment Law, domestic investors and foreign investors enjoy equal treatment.

In addition to prohibited investment projects that endanger Myanmar’s national interests, foreign investors can participate in multi-sector investments. Myanmar encourages foreign investment to adopt BOT and PPP investment methods and actively invest in green environmental protection, high-tech, professional and international industries.

In addition, investors can lease private land or buildings for investment projects for a long period of time. The lease period is 50 years, which can be extended 2 more times for 10 years each time.

Myanmar is rich in natural resources. The main mineral deposits that have been proved are copper, lead, zinc, silver, gold, iron, nickel, ruby, sapphire, jade, etc., and some minerals are mined in large areas. Myanmar contains relatively rich oil and natural gas resources. Natural gas is one of the main products of Myanmar to earn foreign exchange. Myanmar has a forest coverage rate of 52% and rich forestry resources; the rivers are densely packed in the country, and the potential of available water resources is huge. In addition, Myanmar has low labor costs, and the United States and Europe provide GSP treatment to Myanmar, which has obvious advantages in labor-intensive industries.

Myanmar’s economic potential is huge. Relevant research institutions are generally positive on Myanmar’s medium-term outlook for reform, and it is expected that future economic growth will remain relatively strong. Myanmar’s domestic market has great potential and is an important channel connecting the two major markets of Southeast Asia and South Asia. It can extend the market to a certain extent.
