Another year has passed, and a new year has just begun. What can we share and learn when we talk about lighting? This is the year when LEDs once again show their strengths, leading with more than just light, it can go beyond its function to illuminate an area.

In this year's first blog post, we reviewed 3 areas of LED Light China development last year.

Solar Street Light Lighting and Health
A study from Oregon State University has shown that the blue wavelengths produced by LEDs can damage cells in the brain and retina if you are exposed to flashlights for extended periods of time. For example, blue light may come from devices such as your smartphone. It shows that it can -- in the long run -- affect your entire life, even if the light isn't shining directly into your eyes. The study itself has been tested on fruit flies, but the technology hasn't been around long enough to draw conclusions about its impact on people's lifetimes.

Having said that, we have seen the development of human life in the last year. Because of artificial light, among other things, it is the cause of the treatment of disease. Science tells us that designing the spectrum can help improve sleep patterns, well-being and overall health issues.

LEDs help increase milk production
UK farmers in particular are feeling the pressure of rising prices, using LED High Bay Lights to boost milk production. Analysis showed that if cows were exposed to a minimum of 160-200 lux of light for 16-18 hours and then in the dark for up to 8 hours, this would have a positive effect on production. This approach is the same as what happens to us humans, because light signals the release of a hormone called melatonin, which affects the increase in mammary glands, which in turn produces more milk.

Blue and red lights in the office
Researchers from Rensselaer Polytechnic Institute's LRC (Lighting Research Center) and the U.S. General Services Administration have published a series of analyses showing how different types of light affect us humans. If you choose to combine bluer lights in the morning with red lights in the afternoon, it will make employees more focused, productive and less sleepy.

Generally speaking, most people don't have enough light during the day. There is a correlation between too little light during the day and too much light at night. It's natural for us humans to use electronic devices when we get home, but the light from screens can trick your brain into thinking it's time to wake up, and vice versa. Disrupting our circadian rhythm affects the biological systems and cells of the brain. Circadian rhythm disturbances are associated with human rest and activity patterns, which can affect our productivity, overall health and well-being.

We can conclude that there is a lot of interest in research and analysis of the effects of LEDs on humans. At Lightemitd, we stay up-to-date and we look forward to seeing what 2022 can expect from knowledge and learning.
