New Limerick Research Competition…

An English surgeon named Treves
looked at cadavers from graves
He cut up the guts
claimed this was what’s up

Offal! said J. Calvin Coffey,
You’ve wrongheadedly researched the mesentery
Irish to bag it together,
and no longer be spilling the guts!

‘We are now saying we have an organ in the body which hasn’t been acknowledged as such to date,’ said J. Calvin Coffey, a study author and surgeon at the University of Limerick, Ireland. The mesentery is a fatty membrane and without it the intestines would slop around in the belly. (ALAN PLACE/UNIVERSITY OF LIMERICK)  

 There seems a mad rush to use blue light in your Fridge.

FrigdeSmallPic

A new stainless steel fridge might look nice in your kitchen, but open the door.

What do you see? Is this what food looks like on your kitchen counter or table?

Is this what the food looked like when you bought it?

Light, and the colour of light, affects how we see the environment around us.

Do you want to see food that looks artificially cold, or do you want to see food in the correct light?

The purpose of fridge lighting is to communicate information; we need to see food, and its colour, to decide if it is healthy to eat.

Does a steak look blue, grey, or red fresh and ready to cook & eat? The colour of food helps tell us if is healthy to eat. Is opening your fridge a pleasurable experience?

Can you see everything? Does the food look good? What can you see?

LEDs can provide excellent optical control of light beams in low profile housings. Fridge interior area lighting may be improved with multiple low profile LED lights vs. past methods that used a single fridge lamp.

LED lighting does not have to have poor colour rendition. It is possible to have correct and accurate colour LED lighting in fridges.

Does the food in your supermarket refrigerator case look correct? Much supermarket food is now being lit with linear strip LED lighting. Custom LED lamp phosphor blends can offer accurate colour lighting.

What do you see inside these fridges? Does this look like food you want to eat?

Could fridge interior blue light imply a false sense of food temperature & appearance?

Will blue colour light make you think food is cold, when the fridge is off?

Does fridge lighting make food look like un-ripened fruit that should be left to ripen, but due to colour appearance might be left to rot?

Accurate light colour rendition seems a common sense consumer protection safety issue.

Should a 2000 dollar fridge come with a 2 dollar light?

Fridge interior visual design experience is important, as is accurate and well placed glare free lighting. Fridge manufacturers need to invest in more in how and what consumers see, to meet expectations, and ensure food safety.

There are standards for lighting colour quality.

Do consumers need protection from poor quality lighting colour? Yes they do.

Conversations on film making often seem to start with hardware.

Film making is not about hardware, there are no magic bullets, it is all about the story.

What do you want to say, and how do you want to say it?

For film the next question is what do you want to see & how do you want to see it?

Robert Primes at [3 min] discusses how words are poor descriptors of visual information.

The time investment to craft a well told story or marketing program is not well understood. In a 4 month re-write of product catalogues & manuals, the product never changed, but 18 months later, sales doubled because the story changed.

Consider a Play.
Well written Scripts take time, and Actors must rehearse. When the Director is satisfied, the first curtain goes up.

We end up back to the idea that it all starts with the story.
What do you want to say, and how do you say it?
What will viewers see, and how will they see it?

With limited viewer attention time you must have effective efficient delivery of stories and video can deliver. Jack Welch is quoted as saying, “You can’t manage what you do not measure.” It is easy to measure video viewers. However now there may be new tools to measure the effectiveness of the well told story.

Dr. Paul Zak used an emotional film to measure how our brains respond to effective storytelling.  As part of this research brain neural activity was measured of viewers. He discovered even a simple narrative, if it follows elements of the dramatic arc of exposition, rising action, climax, falling action, and dénouement, described by playwright Gustav Freytag, can evoke powerful empathic responses associated with neurochemicals cortisol and oxytocin.

Brain responses to storytelling can translate into actions. In Dr. Zak’s research his subjects increased donations to charity and gifts to others in the research group.  He found stories that did not follow the dramatic arc, no matter how happy or pleasant they may be, produced little if any chemical or emotional response, and lacked a similar response to action. His research contains clues on measuring the well-made story.

This was the test story.

Pictures Better Than Words?

Teachers know the problem is not content but delivery. Using text only email, introduces a reader time consumption problem. Best text is distilled like poetry with pictures & video for effective delivery. Understanding the Picture Superiority Effect helps deliver.

“When it comes to memory, researchers have known for more than 100 years that pictures and text follow very different rules. Put simply, the more visual the input becomes, the more likely it is to be recognized—and recalled. The phenomenon is so pervasive, it has been given its own name: the pictorial superiority effect, or PSE.”   John Medina

For insights on conventional light sources vs. LED sources and their colour rendering performance for Film & DSLR video see these tests.

I. The Academy of Motion Picture Arts & Sciences, Science & Technology Council Solid State Lighting Project

“The Academy of Motion Picture Arts & Sciences, Science and Technology Council has identified a need for an unbiased investigation of solid state lighting (SSL) technologies, which includes LED emitters, for motion picture production. Issues with SSL have been identified regarding its ability to supplement and integrate with existing lighting technologies such as tungsten, fluorescent, HMI, and Xenon that are currently used in the production of motion pictures. The primary purpose of this investigation is to provide the industry with data needed to properly evaluate the impact of using SSL, as well as to provide a framework for the evaluation of future light emitting technologies as they are developed. The Council’s current efforts are focused on providing the motion picture industry with accurate and previously unpublished radiometric and photometric measurements (e.g., spectral power distribution, radiant flux, luminous flux, etc.) typical of various LED light sources currently in use.”

Babies undergoing phototherapy for hyperbilirubinemia, have eye masks to prevent risk of UV exposure and to eliminate risk of retinopathy of prematurity. Lights in neonatal wards are not allowed on 24 hours a day. Direct & bare lamp use is not allowed.

Phototherapy lamps used have a special phosphor coatings only for bililights. As an added precaution the bililights I designed use a museum quality acrylic UV filter.

Newer medical research indicates a slight shift in action spectrum may speed photo therapy. LEDs can be used for this phototherapy. Much research has found them to be as effective as the special fluorescent bililamps, however as LEDs have a more pronounced spectral peak, it may be possible that superior combination of LEDs and phosphors may replicate a faster reacting action spectrum.

LEDs can offer similar, if not the same phototherapy as the best fluorescent bililamps, but as all lights dim in brightness as they age, control algorithms for LEDs can ensure maintained light levels are delivered for a 15 year bililight source service lives. This is not yet being done for phototherapy but I trust testing may soon start.

Both terms and their effects, need simultaneous review when discussing LED performance decline over time.

Depreciation commonly is used to refer to the decline in brightness over time as a light source is used, known as lamp lumen depreciation.

LEDs also degrade.

Degradation, many may think of chemical decomposition but there is also elegant degradation. One or both of these conditions seems commonly referred to, and one or both, may occur at the same time.

LED performance depreciates over time as less lumens are emitted. The more any light is used, the more a light source brightness dims over time.

LED lumen depreciation can be solely due to heat conditions. Research has verified this independent of LED operation.

Evidence of LED lamp lumen depreciation is useful, however we know in addition to lumen deprecation, LED Kelvin CCT (Correlated Color Temperature) changes over time.  If change in apparent colour appearance of an LED, and lumen depreciation are plotted at the same point, we can see how these changes may parallel each other in some LED sources, while for others, they may be independent.

Decline in LED lamp lumens and colour temperature change over time varies between manufacturers. It seems sensible to test LED Kelvin CCT measurements and plot them at the same time as Lumen measurements are taken when LED life performance testing is conducted.
