What is the strobe of LED lamps, how to solve?

Strobe is a kind of flicker that occurs due to frequency. The stroboscopic phenomenon of the light source means that the light emitted by the light source changes rapidly and repeatedly with time, making the light source jump and unstable. Studies have shown that stroboscopic light sources are closely related to neurological diseases such as migraine, headache, autism, visual fatigue and discomfort, which can seriously cause illusion to the human eye.

which in turn caused an accident.

The cause of the strobe:

The driver of the luminaire does not have suitable electronic circuits, such as ballasts, drives or power supplies. Source will produce stroboscopic light. Greater the fluctuation of the output luminous flux, the more severe the strobe.

As for the LED lamp, from the theory of illumination, the LED lamp itself does not produce stroboscopic, and the presence or absence of strobe depends on the LED driver circuit. Due to the wide variety of drivers, the stroboscopic performance of each LED product is different. In particular, some manufacturers use a relatively simple driver chip in order to save costs, there will be a large stroboscopic problem.

In addition, many LED lamps use a PCB board with soldered beads, which has high requirements on the driving power supply, and any minor errors such as quality problems on the hardware may cause dead beads, stroboscopic, and uneven color of light. Even not at all.

Strobe solution:

1. The LED lamp bead does not match the LED driver power supply. If the lamp bead chip is not full of power, it will cause the strobe phenomenon of the light source. If the current is too high, the lamp bead can not be withstood, and the lamp will be built into the gold. The wire or copper wire is blown, causing the lamp bead to be off.

2. If the drive power supply is broken, just replace one drive power supply.

3, the drive has over-temperature protection function, and the thermal performance of the material of the luminaire can not meet the requirements, and the driving over-temperature protection will start to work and there will be a flash.

Your child must not cough their childhood away!

Authored by – Dr Sunil Kumar K, Consultant – Interventional Pulmonology, Aster CMI Hospital

An initiative by WHO, World Asthma Day is observed yearly on May 7th, with the aim to raise awareness on the growing rise of asthma across the world. India has recently been in the limelight for being the second country in the world with the largest number of cases of asthma in children in India caused by vehicular pollution. According to a study published by The Lancet recently,it was found that 3,50,000 children in India developed asthma due to vehicular pollution. With the theme for this World Asthma Day being “STOP” for Asthma, let us understand how we can ‘STOP’ the spread of asthma in our children!
Asthma arises either due to genetic factors or as a result of external irritants.A family with a long line or descendants with asthma is more likely to produce an offspring with asthma. Apart from genetic, external factors include outdoor pollution (dust, pollen, unclean, polluted air) and indoor pollutants like house-mites, dusty rugs/house décor, filthy animals or insect residue. Women who smoke/ who are exposed to tobacco smoke during pregnancy also have a greater risk of delivering a baby who could develop asthma. There have also been deeper investigations into the correlation between urbanization and the development of asthma in children.
Generally speaking, a decade or so back cases of asthma were due to genetic factors. However, there has been an alarming rise in the cases of asthma that observed off late and a large portion of this has been linked to the increase in outdoor and indoor pollution. Symptoms of asthma generally occur during the early years of a person and may either gradually stop or it may be an issue that continues into adulthood. The signs of asthma in a child are the same as the signs of asthma in adults however the impact on a child is much direr.
To prevent the development of external pollutant induced asthma in our children, it is important to take precautionary measures right from the time of pregnancy. Avoid exposure to heavily polluted areas – the family may even consider moving to a greener neighborhood. It is advisable to equip children with a face mask to reduce the amount of pollution that they inhale. It is also advised to ensure children have a well-rounded diet and ample exercise to help their immune systems fight off any respiratory diseases that may exacerbate the likelihood of asthma development.
Asthma must be detected and managed early, particularly in the case of children as it can be scary if they get a serious attack. Symptoms can vary from a mild cough to persistent, sever cough, chest congestion, shortness of breath, chest tightness or wheezing. If any of this symptoms already exist and these are exacerbated by an external infection (viral) and if these symptoms don’t go away even after the infection has passed, then it could be a sign that the child has developed asthma.
A common problem faced by doctors today is that of self-treatment by patients. Often pharmacists advise patients on opting for different kinds of treatments to manage asthma however this is counterproductive. First and foremost, a parent must bring their child to a doctor for diagnosis before coming to any conclusions, as often what parents fear to be asthma in their child can be another respiratory illness. Asthma is a disorder that unfortunately cannot be treated but can be managed and typically doctors prescribe the use of inhalers to help control asthmatic attacks. However, in the case of a respiratory disease like the flu or other similar viral infections, it can be treated. If asthma is detected, the doctor will further be able to guide the patient on what treatment option is suitable for.
Pediatric asthma can drastically be reduced if efforts are taken to reduce the amount of air pollution we create. The issue must be tackled holistically with ample public and private sector effort to cut down on pollution and introduce more green initiatives in the country. India is home to one of the largest youth populations and it is imperative to our country’s future to give our young one’s cleaner and healthier spaces to breathe.

CUMMINS CELEBRATES ITS CENTENARY AT BAUMA

MUNICH, GERMANY – Cummins will celebrate its 100th anniversary at the Bauma show (8-14 April, Munich). Visitors to stand A4.325 will see where it all started, with the company’s first engine known as the HVID. It will be shown alongside the latest B6.7 2019 Stage V engine, highlighting 100 years of engine innovation.

Alexei Ustinov, Vice President Off-Highway Engine Business said: “Our centenary theme is ‘challenging the impossible’ reflecting the spirit of innovation of our founder Clessie Cummins which lives on today in our current employees. Throughout the 100 years Cummins has proven its dependability to our customers by developing market leading products, and we will continue to do this into our second century.”

In 1919, Clessie Cummins founded Cummins Engine Company in Columbus, Indiana USA. backed by banker William G. Irwin. Clessie recognised the benefits of using technology developed by Rudolph Diesel at the end of the 19th century. A design by Dutch engineer Rasmus Hvid was seen by Clessie to be the best available for a small kerosene burning engine used on farms, on boats and in factories. He persuaded W.G. Irwin to invest $2,500 in the license for the HVID, a significant sum at the time, and it became the company’s first engine. 28 of the 6hp units were sold in the first year with around 3000 in total, a far cry from the 1.2 million engines produced by Cummins in 2017.

Long-term challenges with supply of the HVID pushed the company to the brink, so Clessie designed his own engine. In 1924 he launched the Model F with a capability of 12.5hp per cylinder in one, two, three four and six-cylinder configurations. It had over 25% more power versus comparable engines offered in Europe. This was the first of many successful products including the Model U in 1928, which was the first US diesel to have all working parts enclosed and the NH Series in 1946, which built the company’s reputation for durability for more than 50 years. It powered many trucks and industrial applications including Euclid earth moving equipment.

Clessie was particularly thoughtful about how to get press interest in his work. He drove diesel powered vehicles across the US to secure coverage. He used the famous Indianapolis 500 race to test his innovations, having the first car to complete the race without stopping in 1931 and achieving pole position in 1952 using turbochargers for the first time.

Fuel system performance was seen by Clessie as the heart of diesel’s capability and a lot of hos focus was in this area. His Pressure Time (PT) fuel system, also tested on the 1952 Indy car, is a forerunner of today’s high-pressure fuel systems. At the time of his death in 1968, Clessie had 33 patents relating to diesel engines and fuel systems.

In more recent years, Cummins made a major change to its product line-up, with the launch of the B Series in the mid-1980’s. This was a move away from traditional markets with a substantial billion-dollar investment. It was a significant risk for the company during what were challenging economic times, but proved successful. Alongside the pick-up and rigid truck potential, it opened up many opportunities for Cummins in construction and agriculture that had previously been unachievable.

To date over 15 million B Series products have been built, contributing a significant percentage of engines manufactured by the company on a global scale in the US, UK, China, India, Brazil and Russia. The strength and simplicity of the B Series continued the company’s reputation for reliability and durability, powering a wide range of industrial equipment from dump trucks to fork lift trucks, and excavators to wheeled loaders.

“It isn’t just product innovation that made Cummins successful, but also the values of the company and how we go about our business. Our former CEO Irwin Miller had a huge influence on this,” continued Ustinov.

Irwin Miller was the grand-nephew of co-founder W.G. Irwin, and he helped Cummins grow rapidly, leading the company to earning its initial profit in the 1930’s. During this time, he was one of the first manufacturing business leaders to recognise the right of workers to unionise. In 1938, the Cummins Employees Association was formed, which later became the Diesel Workers Union.

Miller recognised the global applicability of Cummins’ products and led the company’s international development in the 1950’s, with the first international factory was in Shotts, Scotland. This was located close to key customer Euclid.

One of his lasting legacies was setting up the Cummins Foundation, which worked to address poverty, racial inequality and environmental issues. He was particularly passionate about civil rights and diversity and lobbied for passage of legislation which would come to be known as the Civil Rights Act of 1964.

“We are proud of our company’s heritage and past success. But, we can’t afford to stop there, and will keep evolving. Cummins’ engineers are developing a range of power solutions to compliment diesel; electric, hybrid, natural gas and fuel-cell. We will continue to partner with our OEM customers to find the best power solution for their needs,” concluded Ustinov.
