Secret LED strobe: How to determine the quality of LED panel light?

An easy way to verify the quality of the LED panel light: using the camera of the mobile phone to align the light source of the lamp. If the camera shows fluctuating stripes, then there is a “strobe” problem in the lamp. It is understood that this kind of invisible strobe phenomenon directly affects the health of the human body. When the eyes are exposed to the strobe light environment caused by poor quality lamps for a long time, it can easily cause headaches and eye fatigue。

The strobe of the light source essentially refers to the frequency and periodic variation of the light emitted by the light source over time between different brightness and colors. The principle of the experiment is that the shutter time of the mobile phone is faster than 24 frames per second that can be recognized by the human eye and the continuous dynamic flashing can capture strobe phenomena that cannot be recognized by the naked eye.

Strobe will have different levels of health effects. The United States Epilepsy Work Foundation pointed out that the factors affecting the induction of photosensitive epilepsy symptoms mainly include the flicker frequency, light intensity, modulation depth and other aspects. Fisher et al. pointed out in the study of epidemic epilepsy epidemiology that patients with epilepsy have a 2% to 14% chance of stimulating epileptic seizures when stimulated by a scintillating light source. American Headache Society says that many migraine sufferers are more sensitive to light, especially glare, bright light with flicker can cause migraines, and low-frequency flicker is more serious than high-frequency flicker. While studying the effects of flicker on people's fatigue, experts found that non-visible flicker can affect the trajectory of eyeballs, affect reading and lead to vision loss.

Light is the only light source available at night indoors. In household use, it’s obvious that the impact of the flash light source on people, especially the elderly and children. Whether studying in the library, reading, or resting in the bedroom, inappropriate light sources not only reduce efficiency, but long-term use may also leave health risks.

Examine the technical mechanism that produces strobe, there is the factor of the power supply, but also the technical performance of the electric light source and lighting design and other factors. For many lighting fixtures, the operating current of the light source fluctuates with fluctuations in the input voltage, which directly leads to fluctuations in the output of the light, which in turn causes strobing. Based on cost considerations, led panel light of many merchants on the market do not use chips with a constant current function, but instead select a common chip that is half the cost, resulting in uneven quality performance of led panel light, causing consumers to confuse their choices.

Comparing to the simple test, IEEE published "Draft Risk Assessment-Potential health effects of flicker from LED lighting" (IEEEPAR1789:2013) in April 2013, and proposed a more professional criteria for strobing. The document states that when the frequency is lower than 9Hz, the undetectable fluctuation depth limit is 0.288%; when the frequency is in the range of 9-3120Hz, the undetectable fluctuation depth limit is the frequency *0.032%; and when the frequency is greater than 3120Hz, it can be considered as no strobe at all.

Analyzing the causes of strobe, we can find that the key to reducing strobe from the product level lies in the electric light source technology and drive technology. The driver products on the market need to consider factors such as driving cost, size, reliability, efficiency and other factors. Manufacturers and industry experts are trying to find a strobe that people can accept.

In fact, our OKT Lighting focus on led panel light manufacture since 2008, we only use Bi-polar Non-flickering driver in our products to reduce strobe fundamentally.

“We product LED product that are increasingly energy-efficient, cost-effective and aesthetically pleasing”, say OKT president.  Welcome to visit our web, we will provide led panel light of the superior quality for you, making what you buy rest assured, using happy and safe.

What do you know about the trivia about light and illumination?

Light is one of the sources of life on earth. It is the basis of human life. It is the tool for human understanding of the outer world. It is also the ideal carrier of information and medium communication. According to the statistic, at least 80% of the total information gained by human senses from the outer world, are through the eyes.

Light is everywhere. But you may be never heard of the trivia about light and illumination.

1. Firefly can glow through the chemical reaction

Luminescence means the light emitted has not any heat, such as the fluorescence light of firefly and other many biological lights. And the energy conversion efficiency of this chemical reaction is nearly 100%. That is to say, it converts almost all the initial energy to the light.

2. Human also can light.

The body light which showed as following photo is taken by the Low temperature charge coupled device camera. All the creatures can emit the light because of the metabolism, human also can shine. But the light emitted from us is too dim. It is 1000 times dimmer than the naked eyes.

3. Centennial bulb

The longest burning time bulb in the world is the centennial bulb in California, USA. It has been glowing since 1901, now in its 117th year of illumination, at least for 110 years, and only has been stopped several times because of the power failures. It has made the Guinness world record.

4. Why did you turn off the light in the car when drive at night?

The reason of turning off the light in the car when drive at night, is related to the physical knowledge of the middle school, that is mirror image principle. When driving at night, if turn on the light in the car, thus the cab is much brighter than the outside car. At this time, the glass of the front of the car to the driver, mirror effect is more than the transmission effect, it is like a mirror. Now, when driver look at the windshield in front of the car, it like looking at a mirror, thus, it is difficult to see clearly of the road ahead.

5. Why emit upwards light bulb when thinking a good idea?

There are many explanations about this answer?

1) At the beginning, bright was used to describe smart and lively.

2) It is related to the bulb which discover by Edison. Because light bulb bring the bright, that means a new civilized process which has profound and great significant. Thus, until now, light bulb is still the symbol of meaning creative, good idea and prompt.

3) The cost of early cartoon is very high. In order to describe the spark inspiration, it is only 2 to 3 steps to finish the light bulb. This simple and popular expression is widely popular in people.

6. Why choose OKT Lighting?

How to distinguish whether LED lighting fixtures are flickering?

LED flicker occurs when its light output fluctuates. This fluctuation happens because your dimmable light-emitting diodes are designed to switch on and off at very high speed.

What’s the negative impact of LED flicker?

Maybe you have already found LED flicker made your eyes uncomfortable. But it has much unexpected harm.

First, LED flicker is harmful to human health. If you work under a flickering light, your eyes will easily feel tired and your sight will become blurred soon, you even will get a headache. Flicker can cause some epileptic seizures. It also can increase the repeatedly actions done by autistic children.

Second, LED flicker may lower productivity and safety in industry. The workers, doing a job with high requirement of vision,will be obviously influenced by flicker. What’s more, flicker is dangerous for the workers operating rotating machines. Because the direction of rotating machines we see sometimes is opposite to its true direction under a flicker light.

Third, LED flicker leaves stripes on your photographs.

How to distinguish whether the LED lights are flickering?

If you wonder if the lights are flickering, the simplest way is using your cell phone. You can take a picture under the lights and check if it has stripes.

Can we avoid flicker, or how can we choose flicker-free LED lighting fixtures?

Yes, what you need to consider about is the drivers!

In the USA, mains electricity is an alternating current (AC) supply, delivered at a frequency of 60 hertz, which means that the electric current powers your lights – switches backwards and forwards 60 times each second! This is the key factor to cause LED flicker.

There are two steps to solve this problem: The first step is changing the alternating current into the direct current, and get constant-voltage current; the second step is changing the constant-voltage current into the invariable current. And all these happen in the drivers!

All led lighting fixtures from OKT Lighting use excellent double-pole no flickering drivers, which can ensure a steady and invariable current and make light uniform without flickering. Its main products include led linear light, led pendant lights, led panel light, led flat panel light, led troffer, led downlights and emergency led driver, all of which have achieved certifications such as UL, ETL, Energy Star, DLC, TITLE 24, TÜV, CSA, SASO and FCC, and come with a minimum five-year warranty.

The new vision on how to maximize the value of LED lighting

But what if we could add a new axis of innovation to the work environment? What if in addition to improving the tools in our spaces, we could also improve the productivity of workers and at the same time increase efficiency?

In terms of lighting, we can improve the workplace experience by thinking about building design in an entirely new way. There are emotions associated with buildings, and many of these emotions are conjured from the effects of lighting on people.

A dark, poorly lit space is sterile and cold. The hum and slight flickering of old fluorescent lamps is corrosive to concentration and therefore performance. The best spaces, where lighting works with the environment, evoke positive emotions of happiness, healthiness, and energy.

The advent of LED lighting has provided more consistent and positively scalable lighting outcomes. LEDs offer huge energy savings, flexibility, and reliability, and are now entering nearly every application in the built environment.

For more than 50 years, dimming technology has been available for commercial spaces, although previously it was considered prohibitively expensive for most general lighting applications. Light levels were altered by directly adjusting the fixture's electrical power circuit. And while there are LED lamps that can be managed with the previous generation of controls, the future lies in embedding the control capability into the LED's driver and using digital protocols that communicate to the driver directly.

The new vision on how to maximize the value of LED lighting is to not only adjust the intensity of the light, but also the color quality — comprising correlated color temperature (CCT) and color rendering. By controlling both the intensity and the color of the light, the lighting design can provide an additional improvement in occupant satisfaction and productivity.

How to choose color temperature changing lamps?

In addition to observing whether the strobe and Blu-ray are up to the standard, the color temperature is also one of the important selection indicators. In general, the daytime natural light is a high color temperature, and the natural light at dusk is a low color temperature. People tend to be excited at high color temperatures and sleepy at low color temperatures. During purchasing we can directly feel the change of the color temperature of the lamp

According to the above table, it can be seen that not the higher of color temperature of the  lamp, the better. In general, the color temperature of candle is 1850K, dusk is less than 3000K, moonlight is 4100K, and daylight is above 5000K. The most common white fluorescent color temperature is 6500K.

Nowadays, the usefulness of a lamp is not limited to reading on a desk, but it also serves as a lighting for bedside reading. It needs more color temperature intervals. The color temperature during learning is more suitable for 3800k-4200K. It can be brighter at work which enables users more focused, and darker before sleep.

We choose a lamp that can adjust the color temperature, not only good for the eyes, but also not easy to disturb the biological clock.

 Allan zhang, the president of okt lighting, which is the manufacturer of led panel light,led linear light,linear perdant lighting…., suggests that everyone should also correct their bad habits under the desk lamp. If using a desk lamp, it is also necessary to turn on the headlights of the house to avoid the pupil being in a state of intense focus; do not read under the shadow; do not strain you eyes, etc.
