Light a natural factor, enables us to see our world in vibrant color and striking details. It also acts as an indication of when our body must wake up and sleep. If you acutely discern from sunrise to sunset, the color and intensity of the light fluctuates from warm amber to bright light during the day, and back to warm light at sunset, followed by darkness in the night. The nature set-cycle of light brightness and intensity has an intense influence upon health of living beings as it affects the body’s circadian system. The human body has a 24 hour rhythm that has established sleep/wake patterns, and control of physiological functions such as hunger, temperature and blood pressure. When our body is in sync with the rhythm, we feel energized and stabilized, if not we feel drained and lethargic. The minute we wake up, our body gets introduced to lights and the time we snooze, we switch off all our light resources for getting proper uninterrupted sleep.

Lighting Science, a noted brand in next-generation LED lighting solutions, announces the comprehensive results from a study, "The effects of spectral tuning of evening ambient light on melatonin suppression, alertness and sleep", published today in the medical journal Physiology and Behavior1. The study was conducted by the Division of Sleep and Circadian Disorders, at Brigham and Women’s Hospital, a teaching affiliate of Harvard Medical School, with lighting technology provided by Rhode Island-based Lighting Science, makers of the noted GoodNight™ and Sleepy Baby™ pre-sleep consumer LEDs.

As the world of LEDs continue to evolve, manufacturers are fervently trying to get the latest technologies in the hands of consumers. But with a flood of options, end-users are oftentimes inundated with gadgets that have short shelf lives or half-heartedly address their lighting goals. For designers and architects in need of creating flexible spaces, address human-centric lighting and more, USAI Lighting serves up advanced tunable white lighting to address a variety of lighting goals all in one fixture. Check out the below options to harness a host of lighting benefits.

The Lighting Research Center has released a new version of its free, open-access circadian stimulus (CS) calculator with more robust and flexible functionality to help lighting professionals select light sources and light levels that will increase the potential for circadian-effective light exposure in architectural spaces.

LpS 2017 (LED Professional Symposium +Expo) are proud to reveal this year’s event program, for what will be the greatest LpS to date. Joining over 1600 delegates and 100 exhibitors in Bregenz this year will be global experts from industry and research, to focus on multiple lighting applications such as Human Centric Lighting, Transportation, Agricultural, Healthcare and many more.

ALPHABET Lighting (formerly WILA Lighting USA) announces a new human-centric, biological lighting series specifically developed for Circadian Rhythm regulation. These new downlight products are enabled by SkyBlue technology by researchers and former NASA scientists at BIOS. BIOS has entered an exclusive agreement with Ledra Brands to provide true Circadian Rhythm lighting providing many benefits for the occupants in the space.

Last October, GE announced it was planning to launch C by GE smart LED bulbs especially designed to be in sync with the human circadian rhythm in 2016. One of the long awaited bulbs has finally made its way onto the market.

Smart lighting emerged in recent years as a promising technology that has attracted investments from many institutes and LED companies, but further R&D is required before the technology can become truly human centric, said Pei-Ting Chou, Manager, Electronics and Optoelectronics Research Laboratories, ITRI, at LEDforum 2014, which was held on Oct. 24, 2014 in Taipei, Taiwan.
