    Paint the town blue: L.A. bathes landmarks in light toasting Dodgers victory

    It was more than 60 years ago this month that the Dodgers beat the Chicago White Sox and won their first World Series in front of more than 90,000 baseball fans at the Los Angeles Memorial Coliseum.

    At the time, the Coliseum lit its torch to honor the team’s win, and now, after the Dodgers won their eighth World Series Championship, the Coliseum has once again lit its torch. And for the next two nights, the Coliseum’s peristyle will be illuminated in blue light.

    Ever since the Dodgers’ miraculous comeback victory Wednesday night, some of L.A. County’s best-known buildings and attractions have been finding ways to celebrate the Boys in Blue, from the Pacific Wheel on Santa Monica’s Pier to L.A. City Hall.

    Los Angeles County Supervisor Janice Hahn, whose father, Supervisor Kenneth Hahn, helped bring the Dodgers from Brooklyn to Los Angeles in 1958, called for the Coliseum torch to be lit.

    “I thought it would be fitting to light the Los Angeles Memorial Coliseum’s torch in celebration of the Dodgers’ victory at the venue the team played their first World Series winning season,” Hahn said. “We love our team.

    “Every corner of Los Angeles is celebrating today,” she said.

    Up in the hills of Griffith Park, the letter “D” on the Hollywood sign was lighted in blue.

    In Inglewood, a spokesperson for SoFi Stadium said the building’s rooftop Thursday night will display “2024 World Series Champions L.A. Dodgers” in blue lighting. A similar message was already on display on its Samsung infinity screen inside the stadium.

    The celebrations will culminate with a victory parade through downtown Friday and separate festivities at Dodger Stadium. Expect to see plenty of blue.

    illumiPure, Inc. Secures Multiple Patents for World’s Safest LED Lighting Technology


    HOUSTON, May 14, 2024 (Newswire.com)
    –
    illumiPure®, Inc., a leader in innovative LED solutions, is proud to announce two patents for its CleanWhite® 405 nm and 405/470 white light LEDs, the only LED to receive a Risk Grade 0 (EG 0) / Exempt Status rating for safety after IEC 62741 testing. This groundbreaking technology has been patented in the European Union and Japan, adding to the North American patent in 2022. CleanWhite LEDs combine traditional white light illumination, disinfection, circadian rhythm management, and remove the most harmful spectrums of blue light, setting a new standard in health and safety protocols for any indoor environment.

    CleanWhite LEDs are the world’s safest white light LED, being awarded exempt status after IEC 62741, which tests the safety of lighting on skin and eyes. This provides a superior solution to traditional LED lighting. To date, CleanWhite LEDs are the only LEDs to receive Risk-Exempt status after testing.

    CleanWhite LED’s uniqueness is providing a solution that delivers white light illumination, disinfection, and circadian rhythm management, all within a single LED that also removes harmful blue light. The LED uses 405 nm diode in lieu of traditional 450 nm diode to create white light illumination, and in doing so, eliminates the most harmful parts of the blue light spectrum, blue light between 440 and 450 nms.

    In addition, 405 nm light, spiked in the CleanWhite LED, is a powerful disinfectant, making the CleanWhite LED the first and only single LED chip that provides white light illumination and disinfection in a single diode. Unlike conventional disinfection LEDs that require switching modes to activate disinfection, illumiPure’s patented CleanWhite 405 LED fixtures deliver continuous disinfection on surfaces and in the air while emitting pleasant, normal white light.   

    The CleanWhite 405/470 LED also enhances the 470 nm wavelength of light, providing additional circadian rhythm management. The disruption of circadian rhythm, which can be caused by harmful blue light wavelengths, is now being linked to a host of maladies and adverse conditions, including everything from cognitive decline, fatigue, headaches, and trouble learning to increased risk of diabetes, weight gain, and even some cancers.

    “Our innovative LED technology is a game changer for any indoor space,” said illumiPure’s CEO John C. Higgins, “Growing evidence shows the detrimental effects that hazardous blue light has on all of us. CleanWhite LED chips and fixtures not only increase users’ health by removing a host of infectious pathogens but also can help reduce adverse effects to the circadian rhythm of shift workers.” 

    “With patents now secured in multiple European Union countries and Japan, we are poised to deliver this unique solution globally, ensuring environments are not only well-lit but also continuously disinfected, all without compromising human safety or comfort,” added Chris Vennard, the company’s Chief Compliance Officer.

  • WTF Fun Fact 13660 – Blue Light and Sleep

    WTF Fun Fact 13660 – Blue Light and Sleep

    Scientists have made some interesting discoveries about the connection between blue light and sleep.

    Artificial lighting, particularly blue light from LED devices, has a notable impact on us. It disrupts melatonin production, the hormone responsible for regulating sleep, leading to potential sleep issues. But not all blue light is equal.

    Blue Light and Sleep

    LED lights in our gadgets and homes emit blue light, which ranges in wavelength from 380 to 500 nanometers (nm). However, not all blue light has the same effect. Wavelengths between 460 and 500 nm are particularly disruptive to melatonin production, impacting our ability to fall asleep.

    In response to these challenges, researchers have developed innovative “human-centric” LEDs. These lights are designed to support natural circadian rhythms regardless of the time of day they are used.

    The researchers created two types of LEDs, each emitting different wavelengths of blue light. One is tailored for daytime use, emitting blue light close to 475 nm, while the other, intended for evening use, emits blue light near 450 nm. This latter wavelength is outside the range known to disturb sleep.

    Testing the New LEDs

    The research team integrated these LEDs into conventional light bulbs, converting some blue light into red and green with phosphors, to produce white light. They then conducted an experiment in a windowless room, furnished with a desk, treadmill, and bed, equipped with these innovative bulbs.

    Over a three-day period, male volunteers stayed in the room, exposed to different lighting conditions controlled by a computer. This setup allowed for a direct comparison between conventional and new LED bulbs.

    Saliva samples collected from 22 volunteers revealed significant differences in melatonin levels based on the type of LED exposure. The use of the new LEDs resulted in a 12.2% increase in nighttime melatonin levels and a 21.9% decrease in daytime melatonin compared to exposure to conventional LEDs.

    This suggests that the innovative LEDs could promote alertness during the day and enhance relaxation and sleep quality at night.

    Towards a Brighter Future with Blue Light

    This groundbreaking research has the potential to revolutionize the way we use artificial lighting. By aligning our indoor lighting with our natural circadian rhythms, we could improve overall well-being, work efficiency, and sleep quality. The hope is that manufacturers of LED lamps and electronic displays will implement these findings, creating environments that nurture our natural sleep-wake cycles. As we continue to spend significant time indoors, these advancements in lighting technology could be key to maintaining our health and productivity in the digital age.
