Study shows influence of LEDs light on characteristics of tomato seedlings

New research indicates that tomato seedlings of both cultivars (Red 70% + Blue 30%) showed the greatest plant height and the largest total leaf area. The best treatment for the accumulation of soluble protein and soluble sugar contents for Gangmu No.1 and Millennium cultivars were (Red 50%+Green 20%+ Blue 30%) and Red 100%, respectively. The Non-Photochemical Quenching under (Red 50%+Green 20%+ Blue 30%) treatment was the lowest for Gangmu No.1, while it was the lowest under white fluorescent light for Millennium.

The electron transport rate under white fluorescent light treatment was the highest for Gangmu No.1, while it was the highest under (Red 70% + Blue 30%) for Millennium.

The results indicated that the mixture of red and blue at (Red 70% + Blue 30%) was beneficial for the growth of tomato seedlings for both cultivars, which could be efficiently used in plant factories and provide some data for different LED light ratios applicable in a closed system to demonstrate how to get the best lighting conditions for tomato seedlings.

A spectacular fire-like lighting system in a swedish forest

In the heart of a swedish forest, UMA designed an outhouse of a summer house with a unique lighting system that mimics a fire.

The clients wanted a simple, no-frills red shed that would quickly replace their previous outhouse, which burnt down due to a party-related accident.

The architects believed that this was their chance to turn a rather dull design into something more interesting, giving it the perfect twist. Additionally, the fire had a great bonus: it scares off deer and rabbits from the forest that have a tendency to feast at the client’s crops next to his house in addition to carrying around hundreds of ticks that can cause serious illness to humans.

Ford’s New Headlights are Ahead of the Curve When it Comes to Making Night Driving Easier

Driving at night, especially on winding unfamiliar roads, can be stressful. However, Ford is looking into new ways of making driving in the dark easier and more comfortable.

The company first pioneered using road signs and lane markings as cues to adjust headlight beams to better illuminate the road ahead, especially around junctions.

Now, engineers from Ford Research and Advanced Engineering Europe are testing technology that uses real-time location data to effectively show the car the way to go. The predictive smart headlight system directs beams into upcoming corners even before drivers may have seen them, illuminating hazards and other road users more quickly and effectively.

The prototype advanced lighting system uses GPS location data, advanced technologies and highly accurate street geometry information to accurately identify turns in the road ahead.

An algorithm calculates the trajectory and speed of the vehicle to proactively adjust the direction of its headlights, providing optimal light coverage of bends, junctions – and even hazards lurking around the corner.

If the vehicle encounters a stretch of road where location data is not available, the system will work alongside camera- and steering‑based dynamic headlight bending technologies to continue to intelligently light the road until the location data improves.

Researchers have made extensive use of “digital twin” simulation that recreates the physical world in a virtual environment. The simulator accurately calculates how light falls and reflects in the real world, enabling researchers to better visualise and optimise the technology for drivers.

Waffle Pendants absorb sound and illuminate communal spaces

ROHM Introduces New White Chip LEDs

ROHM Semiconductor introduced their new CSL1104WB ultra-compact, high luminous intensity white chip LEDs.

The products are optimized for applications requiring high brightness white light emission, such as IoT devices, drones, and other battery-equipped applications.

In recent years, high luminous intensity (2.0cd) white LEDs have been increasingly adopted to improve visibility in a range of applications in the consumer electronics and automotive sectors. At the same time, the emergence of applications that mount multiple LEDs in a small space – such as IoT devices and drones – require high density mounting. This makes it difficult to achieve high brightness in a compact footprint.

The CSL1104WB series achieves a high luminous intensity of 2.0cd in an ultra-compact 1608 size (1.6mm x 0.8mm = 1.28mm2), which was previously difficult to achieve. The result is the same luminosity as the current mainstream 3528 size PLCC package (3.5mm x 2.8mm = 9.8mm2), but in an 87% smaller form factor.

eLux reaches important milestones in the drive to commercial development of microLED displays.

eLux reached two important milestones in the drive to commercial development of microLED displays.

Optimization and automation of the fluidic assembly process with selective harvest of microLEDs has produced a 12.3” microLED display with a natural yield of 99.987%.

An automated fluidic assembly tool manufactured by an accomplished display panel tool maker is operational in the eLux prototype fab located at Taiwan.

The 12.3” demonstration display with 99.987% natural yield consisted of 518,400 GaN microLEDs assembled in 10 minutes for an assembly rate of 3.1 million devices per hour. There were 34 failing subpixels, of which 33 could be laser repaired to achieve after repair defectivity approaching one part per million.

Given that a 4K television has 8.3 million pixels this result is approaching the quality level require for a microLED television. Of the 34 defective sites 19 were caused by shorted microLEDs so additional refinement of the inspection and selective harvest processes will be required to produce defect free displays that do not require repair.

Samsung Introduces PixCell LED for Intelligent Headlight Systems to Enhance Road Safety

Samsung Electronics announced PixCell LED, a new automotive LED module optimized for intelligent headlights, such as adaptive driving beam (ADB) systems. ADB headlamps powered by Samsung’s PixCell LEDs will help improve driver visibility and safety to enhance the overall driving experience at night and in poor weather conditions such as fog or heavy rain.

ADB is an advanced driver assistance technology designed to help secure maximum driving visibility. In order to prevent glare to other drivers, ADB automatically adjusts headlight beam patterns when it detects any object near a moving vehicle, thereby preventing any unnecessary glare. Recent developments in future automotive technologies, such as autonomous and connected driving, have been raising the bar for vehicle safety standards and ultimately boosting demand for ADB systems.

Leveraging Samsung’s longstanding expertise in semiconductor technology, the new PixCell LED can monolithically integrate more than 100 ultra-small segments into a single LED chip, while making the light-emitting area significantly smaller.

These LED segments are separated by a silicon wall to prevent optical cross-talk, and in turn, offer superior contrast for much greater driver visibility. Each segment functions like a pixel to meticulously control light distribution, as it distinguishes on and off areas so that the beam from the headlight only illuminates the exact location where it is needed.

GE Lighting Introduces Its Closest Light to Natural Sunlight

GE Lighting is helping consumers maintain their circadian rhythm, the body’s natural sleep-wake cycle, because when we sleep well, we feel well and our best selves can fill the day. New GE sun filled LED bulbs do not emit the invisible blue spectrum peak that can interfere with the body’s circadian rhythm, making it easier to get the kind of sleep dreams are made of. And by enhancing the color appearance of objects,* these bulbs pack more benefits owners will enjoy.

Now consumers can bring the sun inside by replacing common household bulbs with GE sun filled LED bulbs that do not require apps or controls to operate. Making the switch in table lamps, flush mount fixtures, flood lights and ceilings is as easy as screwing in a new bulb—few sleep hygiene tools are as simple and affordable.

As GE Lighting, a Savant company’s closest light to natural sunlight, the GE sun filled LED bulb helps individuals maintain a natural sleep/wake cycle to feel restored and more alert each morning. It delivers a high CRI value of 97 to render colors that look much like they would appear in natural sunlight (the standard for illuminating colors with a 100 CRI value). The result is a beautiful, clear light that brings out the color in home décor. The new bulb, with an R9 of 80+, also reproduces reds exceptionally well. Most LED light sources carry an R9 rating of 10 or less. With the GE sun filled LED bulb, there’s a lot to like and nothing to do—no adjustments, no programming, no settings to change.

GE sun filled LED bulbs can be used almost anywhere in the home in place of other bulbs. Simply turn off all artificial light sources and turn on GE sun filled LED bulbs a few hours before bedtime to eliminate the blue light spectrum that can interfere with a good night’s sleep.

The new bulb emits a spectrum that is closer to sunlight than ordinary LEDs by eliminating the 450-nanometer wavelength (the blue spike) present in many artificial light sources. These bulbs allow consumers to get their favored soft white light all day long without the need to change light temperatures when calling it a night.

The science behind varying performance of different colored LEDs

Researchers from the Low Energy Electronic Systems (LEES) Interdisciplinary Research Group (IRG) at Singapore-MIT Alliance for Research and Technology (SMART), MIT's research enterprise in Singapore, together with Massachusetts Institute of Technology (MIT) and National University of Singapore (NUS) have found a method to quantify the distribution of compositional fluctuations in the indium gallium nitride (InGaN) quantum wells (QWs) at different indium concentrations.

Currently, red and amber LEDs are made using the aluminum indium gallium phosphide (AlInGaP) material instead of InGaN due to InGaN's poor performance in the red and amber spectrum caused by the efficiency drop. Understanding and overcoming the efficiency drop is the first step towards developing InGaN LEDs covering the whole visible spectrum that would significantly reduce production costs.

LED Brightness Adjustment Uses Itself As Sensor

Since LEDs can be used as light sensors, inventor Mitxela saw an opportunity to use elements of the clock displays themselves as sensors. This is how it works: a charge in the p-n junction that makes up an LED will decay at a rate proportional to the amount of light hitting the junction. By measuring the speed of this decay, it’s therefore possible to tell how much light is hitting the LED. It’s effective and elegant, but there are a few practical issues to deal with.

Signify’s new fish lights increase growth

Signify launched new Philips solar fish grow lights that help to optimize farming for ponds, while harnessing the power of the sun. It provides spectral light specifically designed to suit many fish species, including tilapia. The grow lights enable fish farmers to increase fish productivity and efficiency.

Research by the South China Agricultural University in a commercial size trial at a tilapia farm using 60 solar luminaires in a 7,000 m2 pond confirmed a 10% increase in fish growth and a 10% reduction in feed conversion ratio (FCR), meaning that fish farmers need less feed per kilogram of fish.

Based on an earlier study in cooperation with the Ocean University of Shanghai South China Agricultural University started the trial in a live setting. This new trial, done at the tilapia farm in Taishan, Jiangmen, Guangdong in the south of China, proved the impact of the new solar fish lights, confirmed a 10% improved growth and found a positive effect on water quality. The commercial size trial lasted 117 days and resulted in an additional 1,770 kg of tilapia that was harvested compared to the reference ponds.

The Philips solar fish light is easy to install and only one luminaire is needed per 100-150 m2 of pond surface. The luminaires, equally spaced in the pond, are attached by rope to the center line or to each other to keep them in place. The best operation is achieved with clean solar panels and LED unit.

The multi-billion dollar quantum dot-enabled market will experience further growth this year, with market innovations leading to enhanced products in displays, Micro-LEDs, security tagging, medical diagnostics, quantum computing and Agtech, according to new research.

QDs are a proven and scaled technology and relatively low cost for the high-end applications they add value to. Quantum Dots (QDs) are used in a range of optoelectronic devices, including TVs and displays, light-emitting devices (LEDs), solar cells, photodiodes, thermoelectrics, photoconductors and field-effect transistors, while QD solutions have been used in a number of in vivo and in vitro imaging, sensing and labelling techniques.

Lettuce grower slashes propagation time with Signify LEDs

A year after converting the lettuce section of its 17 hectares of vegetable and flower greenhouses to all LED lighting, a British Columbia grower is reporting positive results.

Prior to the LED installation, Canadian Valley had considered combining LED and HPS lighting in both the propagation and finishing section of its lettuces, which occupy less than a hectare of the group’s total crop area. It decided on all LED, deploying about 1500 Philips GreenPower toplights from Signify in late 2019.

By going to a more intense LED in prop, the grower sees more even and consistent plant.
