The US EIA that releases the data is part of the US DOE. The 2020 Residential Energy Consumption Survey (RECS) provides household characteristics and energy usage indicators for the estimated 123.5 million homes in the United States in 2020. The first release of 2020 RECS data includes preliminary estimates on the structural and geographic characteristics of homes, types of electronics and appliances used within them, lighting characteristics, demographic characteristics, and household energy insecurity.

Between 2015 and 2020, homes with most or all indoor LED lighting increased from 4% up to 47%. Over the same time period, homes using mostly or all incandescent or halogen dropped from 32% down to 15%. In 2020, 82% of homes used at least one LED indoor bulb, while 61% of homes used at least one incandescent or halogen bulb indoors.

Light-Operated Computer Chip Implements All 5 Basic Logic Operations Without Electricity

The demand for next-generation computers that can quickly calculate and process a lot of information is rapidly increasing. A logic device is a circuit that obtains an output value by applying one or more logic inputs to certain logic operation (AND, OR, etc.). A logic circuit can be made by combining a plurality of electronic transistors.

The demand for next-generation computers that can quickly calculate and process a lot of information is rapidly increasing. A logic device is a circuit that obtains an output value by applying one or more logic inputs to certain logic operation (AND, OR, etc.). A logic circuit can be made by combining a plurality of electronic transistors.

GIST (Gwangju Institute of Science and Technology, President Kiseon Kim) School of Materials Science and Engineering Professor Gun Young Jung’s research team along with Dr. Yusin Pak’s research team at the Sensor System Research Center at the Korea Institute of Science and Technology (KIST, President Seok-Jin Yoon) developed technology for optical-logic devices that operate with light using organic and inorganic perovskite* materials.

The research team focused on optical-logic devices that use light with low physical energy loss as an input signal. For this purpose, organic and inorganic perovskite that absorbs light to generate electricity was used. They succeeded in developing a stacked perovskite optical-logic device in which two types of perovskite thin films with different light absorption spectra are stacked like a sandwich.

It has been proven that the desired binary logic operation is possible by inputting two lights of different wavelengths and intensities. Optical-logic devices using light operate only with light energy without electricity, raising expectations for the development of power-free optical computer processor chips. Logic operation is an operation applied to one or two binary numbers and refers to a system that derives a result value according to a set rule.

Existing logic devices can only perform one logic operation, but the perovskite optical-logic device developed by the research team can perform and implement five different basic logic operations with one device: AND, OR, NAND, NOR, and NOT.

Circadian Lighting Pioneer Says The Science Isn’t Ready Yet

Mark Halper has an interesting article in LED’s Magazine interviewing Russell Foster, the scientist who predicted the non-visual receptors in the eye that are involved in the circadian response to light (pRGCs / ipRGCs). He says circadian lighting science isn’t ready yet, and there are too many unknowns.

Mark Halper has an interesting article in LED’s Magazine interviewing Russell Foster, the scientist who predicted the non-visual receptors in the eye that are involved in the circadian response to light (pRGCs / ipRGCs). He says circadian lighting science isn’t ready yet, and there are too many unknowns.

“We’re not ready yet,” said Foster, professor of circadian neuroscience at the University of Oxford. “We’re shuffling closely toward it, but there are major questions that remain unresolved. Yes, the toolkit is better than anything we’ve had before, but it is not the complete answer yet. We haven’t got the data to plugin.”

This is hardly what you’d expect from someone who, in the 1990s, posited the notion that certain cells in the eye’s retina receive light that has nothing to do with processing vision but has everything to do with maintaining the circadian rhythm.

Foster’s pioneering, decadelong hunch proved correct in 2002 when Brown University professor David Berson uncovered nonvisual photoreceptors, known as photosensitive retinal ganglion cells (pRGCs). Foster himself also found them soon thereafter.

“There are many critical factors — intensity, duration wavelength, time of day, task, a person’s light history, their age,” Foster pointed out. “All are really important. There’s this level of complexity, and we don’t know the answers to many of the important questions” that need answering in order to develop truly effective circadian lighting.

Section 301 Tariffs Could Expire And USTR Reinstates Some Exclusions

According to the American Lighting Association (ALA), the first $34 billion of Section 301 tariffs on products coming from China have been in place for almost 4 years.

Tariffs Could Expire If No USTR Action

According to the American Lighting Association (ALA), the first $34 billion of Section 301 tariffs on products coming from China have been in place for almost 4 years. Before their fourth year is up, they are required to undergo a Congressionally-mandated effectiveness review. The tariffs could expire if the review is not completed by September 4, 2022.

The review will be conducted by the Office of the U.S. Trade Representative (USTR) as set forth in the Trade Act of 1974. President Biden’s USTR has allowed the Trump-era tariffs to remain in place. The Chinese government has not lived up to its commitments in the Phase One trade deal.

Over the last four years, tariffs have cost America nearly $130 billion dollars. The subsequent Section 301 tariffs will also follow a similar path, as their four-year anniversaries approach, in the months ahead.

USTR Reinstates Some Exclusions

As the Section 301 tariffs have evolved, the U.S. Trade Representative (USTR) created and implemented a tariff exclusion process. To date, USTR has approved 549 requested exclusions, but all of those have since expired.

After six months of urging by industry, USTR has reinstated 352 of the original 549 exclusions. The reinstated exclusions are retroactive to Oct. 12, 2021, and will be in effect for the remainder of 2022. The full list of reinstated exclusions is here.

Identified exclusions impacting lighting:

8536.50.9065
Modular light switches, for a voltage not exceeding 1,000 V, presented in polyethylene terephthalate (PET) housings, designed for use with a backplate

8536.90.4000
Twist-on wire connectors, for a voltage not exceeding 1,000 V, each valued not over $0.03

8543.70.9960 prior to January 27, 2022, or 8543.70.9860 effective January 27, 2022
Apparatus using passive infrared detection sensors designed for turning lights on and off

9405.40.8440 prior to January 27, 2022, or 9405.42.8440 effective January 27, 2022
Flexible strips, each having embedded light-emitting diodes electrically connected to a molded electrical end connector, each strip wound onto a reel measuring not more than 25 cm in diameter and not more than 1.5 cm in width.

UK-Funded Study Publishes “Consensus View” For Circadian Lighting Recommendations

On March 17th, 18 circadian lighting researchers published a “consensus view” of circadian lighting recommendations, titled: Recommendations for daytime, evening, and nighttime indoor light exposure to best support physiology, sleep, and wakefulness in healthy adults, in the journal PLOS Biology. The authors include well-known circadian lighting researchers, George Brainard and Steven Lockley.

On March 17th, 18 circadian lighting researchers published a “consensus view” of circadian lighting recommendations, titled: Recommendations for daytime, evening, and nighttime indoor light exposure to best support physiology, sleep, and wakefulness in healthy adults, in the journal PLOS Biology. The authors include well-known circadian lighting researchers, George Brainard and Steven Lockley.

Three significant aspects of the paper are:

  1. The broad consensus achieved on a set of circadian lighting recommendations in a field known for its lack of consensus, and
  2. The paper focuses on the metric of Melanopic Equivalent Daylight Illuminance (Melanopic EDI).
  3. The paper achieves agreement between researchers in North America and Europe.

Abstract

Ocular light exposure has important influences on human health and well-being through modulation of circadian rhythms and sleep, as well as neuroendocrine and cognitive functions. Prevailing patterns of light exposure do not optimally engage these actions for many individuals, but advances in our understanding of the underpinning mechanisms and emerging lighting technologies now present opportunities to adjust lighting to promote optimal physical and mental health and performance. A newly developed, international standard provides an SI-compliant way of quantifying the influence of light on the intrinsically photosensitive, melanopsin-expressing, retinal neurons that mediate these effects. This new report provides recommendations for lighting, based on an expert scientific consensus and expressed in an easily measured quantity (melanopic equivalent daylight illuminance (melaponic EDI)) defined within this standard. The recommendations are supported by detailed analysis of the sensitivity of human circadian, neuroendocrine, and alerting responses to ocular light and provide a straightforward framework to inform lighting design and practice.
