Human-Centric Lighting Takes LED Technology to the Next Level

The human body reacts to sunlight and darkness by releasing hormones that direct our internal clock, known as our circadian system. Disturbing our internal clock can affect our ability to perform or concentrate and literally puts us at risk for a host of diseases. Recent research indicates that building occupants’ circadian rhythm can be disturbed when they spend long hours indoors without access to the Earth’s natural lighting cycle.

5 Commercial Wireless Lighting Myths that Need Debunking

Some people believe that wireless cannot go the distance for large commercial lighting applications. That is not true. Even with the widespread usage of wireless networks, it is still amazing that there are so many myths about them. That is not a surprise since not everybody has strong IT knowledge. After all, IT can be quite complicated.

The Effectiveness of Apple’s iPad Night Shift Application Tested by Lighting Research Center

The light emitted by portable electronic devices (PEDs), particularly when used at night, has drawn a great deal of interest among sleep researchers, healthcare professionals, and the media. Research shows that exposure to light at night (LAN) may be associated with poor sleep and may lead to diminished alertness and performance throughout the day. Exposure to LAN can also acutely suppress melatonin, a hormone produced at night and in darkness, which tells the body it is nighttime. The short-wavelength “blue” light emitted by electronics can be especially disruptive to melatonin production, and the proximity to the eye when PEDs are in use only aggravates the threat to getting a good night’s sleep.

Rapid Assembly of Quantum Dots for MicroLED Micro-Displays

Inorganic microLEDs are the next big thing in displays, not as backlights for LCDs, but like OLEDs, as the actual light emitting pixel elements, ranging from applications in Micro-displays for Augmented /Virtual Reality (AR/VR) to wearables such as Smartwatches and Cellphones. Unlike OLED displays, however, they are far more robust and long-lived, and most importantly, far more efficient and much brighter, making them viable even for larger displays, such as video walls in advertising and in cinema in place of projection.  But to make the technology cost effective, manufacturing challenges abound, particularly as pixel sizes shrink in next generation micro-displays. For example, various coatings must be rapidly deposited in a precise, controlled manner, such as the Quantum Dots (QDs) integrated with the LEDs used in larger displays either to sharpen the color characteristics of traditional phosphors, or fully replace them in micro-displays, relying solely on QDs for color conversion. Better technology is needed for reliably depositing the various costly materials used, and even for rapidly assembling or arraying the microLEDs themselves.

Improving Quality Assessment Key Step to Boost Quality, Life Cycle and Safety

The difference between displays from one LCD manufacturer to another can often be traced to the LC materials used and the impurity control level employed in the manufacturing process. To stay ahead of the completion, LCD makers constantly strive to improve product performance by minimizing degradation factors, controlling impurity levels in the LC materials, and exploring methods to develop new and better products.

Rethinking Exposure to Saturated Colored Light

Two key physical properties of light participate in color vision: wavelength and power. They factor into a light source’s spectral power distribution, which describes the amount of light power at each wavelength in the visible spectrum (which ranges from approximately 380 nanometers to 780 nanometers) that is emitted by that particular source. Power is a measure of the amount of light from each wavelength that arrives at a defined location per unit time.

Lasers Let LED Makers Pursue Augmented Reality, New Markets …

Augmented Reality (AR) is thought by many, including many of the leading CEOs in Silicon Valley, to be the “next big thing,” ultimately displacing our smartphones with stylish, interactive glasses that communicate with the digital world, in part by superimposing virtual images on the wearer’s field of view. Huge investment is pursuing this vision, much of it focused on micro-displays and sophisticated optics for overlaying images onto a wearer’s view. But just as promising is the idea of scanning such images directly into the human eye. Needed are very low power lasers or laser arrays in RGB or more colors that can be packaged in very small, discreet form factors suitable for integration into attractive, fashionable eyewear. Such lasers do not yet exist, but a technology that meets the challenge is in development, which can also lever the existing manufacturing infrastructure for LEDs. It can also address many other applications in emerging bio-tech and even in SSL markets for highly directional lighting.

An LED-Based Device for Imaging Radiation Induced Skin Damage

To eradicate any cancer cells that may potentially remain after surgery or chemotherapy, many breast cancer patients also undergo radiation therapy. All patients experience unfortunate side effects including skin irritation, and sometimes peeling and blistering. Patients can also develop permanent discoloration of the skin and thickening of the breast tissue months, or even years, after treatment. There is currently no method to predict the severity of these acute and late effects, and even current evaluation of these effects are based on subjective scoring.

Challenges In OLED Research and Development III: Solution-Based Materials

Solution based materials are a different way of processing the conventional OLED materials. So conventional OLED materials are processed by vacuum thermal deposition or heating up a powder in a crucible and evaporating it onto the substrate. Solution process materials are dissolved in a variety of solvents and then they can be coated by spin coating for lab sized experiments, or ink-jet printing, or slot-die coating, or a variety of other printing methods.

Challenges In OLED Research and Development II: Light Extraction

Light extraction is the process of removing light from the device itself. So when the device emits a photon, it gets trapped in the glass, in the organic layers themselves in the metals. And the-- what our challenge is, is to get all of that light into the viewing angle. So that when somebody sees the OLED they're seeing the full efficiency of that device. Rather than having light lost in the various segments.
