To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which has been linked to eye troubles and sleep disturbances. Now, researchers reporting in ACS Applied Materials & Interfaces have developed a prototype LED that reduces -- instead of masks -- the blue component, while also making colors appear just as they do in natural sunlight.To get more news about Led flashlight brands, you can visit flashlightbrand.com official website.

LED light bulbs are popular because of their low energy consumption, long lifespan and ability to turn on and off quickly. Inside the bulb, an LED chip converts electrical current into high-energy light, including invisible ultraviolet (UV), violet or blue wavelengths. A cap that is placed on the chip contains multiple phosphors -- solid luminescent compounds that convert high-energy light into lower-energy visible wavelengths. Each phosphor emits a different color, and these colors combine to produce a broad-spectrum white light. Commercial LED bulbs use blue LEDs and yellow-emitting phosphors, which appear as a cold, bright white light similar to daylight. Continual exposure to these blue-tinted lights has been linked to cataract formation, and turning them on in the evening can disrupt the production of sleep-inducing hormones, such as melatonin, triggering insomnia and fatigue. To create a warmer white LED bulb for nighttime use, previous researchers added red-emitting phosphors, but this only masked the blue hue without getting rid of it. So, Jakoah Brgoch and Shruti Hariyani wanted to develop a phosphor that, when used in a violet LED device, would result in a warm white light while avoiding the problematic wavelength range.

As a proof of concept, the researchers identified and synthesized a new luminescent crystalline phosphor containing europium ((Na1.92Eu0.04)MgPO4F). In thermal stability tests, the phosphor's emission color was consistent between room temperature and the higher operating temperature (301 F) of commercial LED-based lighting. In long-term moisture experiments, the compound showed no change in the color or intensity of light produced. To see how the material might work in a light bulb, the researchers fabricated a prototype device with a violet-light LED covered by a silicone cap containing their luminescent blue compound blended with red-emitting and green-emitting phosphors. It produced the desired bright warm white light while minimizing the intensity across blue wavelengths, unlike commercial LED light bulbs. The prototype's optical properties revealed the color of objects almost as well as natural sunlight, fulfilling the needs of indoor lighting, the researchers say, though they add that more work needs to be done before it is ready for everyday use.

We may not often think about it, but signs play an important part in keeping us safe duringSafety Signage our day-to-day lives. They tell us when to stop at an intersection, if there is construction work ahead or when it's safe to cross the street.Get more news about Protocol Control Signages,you can vist our website!
The same goes for the workplace. Signs play a huge role in telling workers what hazards are present and how they avoid those dangers. To be most effective, these signs must be understandable so that workers will know what to do to stay safe in different work environments.

"Although safety signs and warnings are low on the hierarchy of controls, they are an important part of communicating with employees about the hazards in the workplace," says Diana Stegall, executive vice president of Rivendell Safety Consulting. "Signs that are well-positioned and take into consideration the hazard ‘audience' can be very effective in communicating a hazard and serving as a reminder when no one else is around."
Signage needs to easily and effectively communicate its message to everyone on the job site. Without a clear understanding of the hazards present in different working environments, workers don't have the knowledge necessary to operate safely.

"The purpose of a safety sign is to give people the information they need to act safely, and to provide that information when and where it's needed," says Brian McFadden, compliance specialist at Graphic Products. "If you keep that goal in mind, the regulations and standards for signage become how-to guides and help you make improvements to your workplace communication in the name of safety."

With regard to regulations, the ANSI/NEMA Z535 series of standards establishes requirements for the design, application and use of safety signage. This includes color coding, sign size, text size and viewing distance. For example, the standard states that yellow be incorporated in signage where minor or moderate hazards are present, orange for more serious hazards and red for the most severe hazards.

Using these as a foundation for safety signage, employees begin to understand and recognize the types of hazards associated with different types of machinery and environments.Along with the Z535 requirements, Stegall stresses that employers, safety professionals and others need to consider the "audience" for each sign, which means thinking about the demographics of their workforce.

It's important to know that literacy rates vary from worker to worker and that not all workers may speak the same language. Therefore, signs should be easily understood in whatever language(s) are spoken in the workplace.

"When multiple languages are used in a workplace, signs featuring all those languages are a common solution," says McFadden. "Many signs are available in bilingual formats and custom signs can be created with any selection of languages."

Reliable and Clarity
TruePix is the first product to incorporate Barco's Infinipix Gen2 image processing system. It ensures optimal viewing experience for all types of content. No visual distortions, low latency, perfect sync and no tearing are the hallmarks of this system, says Barco. Infinipix Gen2 also guarantees dimming without any loss in color accuracy. Thus, it drastically expands the effectiveness of the installation. What's more, Barco's proprietary smart calibration method for wide color gamut support and full color balancing control creates rich and true-to-life images. TruePix also shows that visual excellence does not equal high energy consumption. Its EcoPower mode ensures reduced energy consumption which then limits the ecological footprint.

SteadyView, a unique Barco feature, improves viewing ergonomics and reduces eye fatigue. This is especially important in control room environments where the staff intensely use the wall for multiple hours on end. Thus, TruePix is a purpose-built LED wall for critical and high-intensity applications like control rooms and command centers.
Barco highlights possible imperfections in flatness of the walls and level of the floors which often cause mechanical stress in the tiles' frames. This then leads to seams, damage or difficulties during maintenance. However, TruePix' auto-balancing system counters these imperfections and makes sure the LED wall is 100% level and frictionless.

For Barco, ensuring longevity, reliability and perfect display uniformity is of major importance. The company says it takes every measure to deliver the promised experiences to customers. Availability of batch compatible modules throughout the life of the wall is therefore a key part of Barco's service offerings. If a module needs to be replaced, Barco guarantees that batch-compatible spare tiles (along with full service support) are available for up to 10 years. This brings peace of mind and a reduced cost of ownership over the full lifetime of the product.

The Video wall Management Suite, Barco's cloud-based platform for advanced video wall management, allows users to monitor, diagnose and/or control the TruePix installation remotely. This maximizes uptime and reduces the need and length of service interventions. TruePix is also the first LED product on the market to leverage 5Gb bandwidth, per a statement. This makes the system up to five times more efficient with fewer cable runs and points of failure - as more LED modules can be connected in a single link. Additionally, 4-way inter-tile communication and signal loop redundancy are embedded to further guarantee an uninterrupted data flow. Thus, TruePix is a reliable LED solution in the market, says Barco.
