Lighting for Corporate Workstations

The short history of artificial lighting [Swan, Edison 1879] has enhanced the visual environment of our homes, our workplaces and our communities, however recent discoveries have shown the profound importance of the nonvisual influences of light on the human body and mind. The retinal response to light not only sends optical information to the visual sensory cortex of the brain, but also directly inputs the hypothalamus which contains the body's internal clock controlling slWorkstation Lightingeep timing and daytime alertness [biological rhythm resetting effect and 'direct' alerting /activation effect]. If understood in terms of our broader biological needs, the indoor lighting environment of today is light deficient in quantity and quality. Such light deficiency promotes a number of identified disorders including insomnia, hypersomnolence, daytime fatigue, reduced work performance and increased accident rate, dietary imbalance, weight gain and depression. Increased "photic" stimulation in terms of intensity, duration, time of day and short-term modulation can reduce or eliminate these disorders.

 

The first fixture is a "soft" light box designed to be used in the workplace. It creates a source of light that gives every office a window. Inspired by the 10K Lux lights used in the treatment of SAD, it has the look and feel of modern office equipment rather than that of a medical appliance. [Patent pending] See final version as Remington's Heathlight at http://www.sphereone.com

Dynamic Arc

The second fixture delivers a real time dynamic motion of flickerfree full spectrum illumination which emulates the quality and changing light in a natural day. This artificial "window" begins the "shift day" by slowly bringing the lowest "sitting horizon" module from 10% to full brightness. The next "standing horizon" module follows this brightening to arrive at its full brightness at about "10.30 am" while the lower unit returns to about 30%. The third "overhead module" arrives at full brightness at "noon" while the "standing horizon" module has dimmed to about 30%. At about "1.30pm" the sequence reverses itself, so that the "sitting horizon" module reaches full brightness again at about "4 pm" and dims to 10% at the end of the shift "day" [5.30pm]. [Patent pending]

The naturalistic dynamic illumination cycles can be controlled by standard network protocols and is able to perform a number of interactive options which include turning the fixture completely off if the worker is not present or dimming the unit for energy saving requirements if nearby windows, skylights [or nearby fixtures] are providing enough illumination. The modular design of the fixture and its flexible programming allow any number of configurations such as wall or desk top use [floor standing shown].


Other nifty ideas looking for the "light of day"--



A "Speed" Ring by any other name 

    The new Plume attachment ring allows additional accessories to be attached to the face of the Ring for various purposes inside a lightbox.  OR, the Ring can become a simple joiner between a task specific accessory and the flash head adapter for any brand of flash. See  a selection of examples below:



 

"SIEVE"  REFLECTOR for use inside a lightbank (softbox) to adjustably direct the light forward while allowing some "leak" into the side walls of the bank.  Holes could be larger or smaller. Now we are cooking? No.
 



The SIDEFLECTOR for use inside lightbanks and as a "stand alone" universal accessory for all flash brands.

Used inside a lightbank—  the SideFlector will create side-to-side or end-to-end graduations.  Perfect for avoiding the over saturation "blooming" associated  with digital capture when photographing broad 100% white highlights on reflective subjects.  A graduated diffusor will fall off from a small area that is 100% white to less bright areas, eliminating the "blooming" ..

Used as a universal accessory— Using the Ring as a joiner between this accessory and the specific adapter for various brands of flash heads, the SIDEFLECTOR can serve as a universal background reflector or corner reflector.


45° REFLECTOR for use within and out of a lightbank.  Less lateral graduation than previous SideFlector, but graduates radially in the other portion of the 360° spread.



 

SNOOT for use as a hairlight in portrait set-ups.  Or a extreme effect inside a lightbank.  Other possibilities include 45° to direct light to a corner of a softbox.  Or transparent tubes of different lengths.


DEFLECTOR for spreading the light radially only.  Useful in lightbanks for  dark graduation for center to corners and sides.  Not readily apparent, but such a negative graduation results in better color saturation when lightbox is double the size of the imaging subject (falloff compensation.


ROUND REFLECTOR, the most conventional expectation, used inside a lightbank for increased "hot spot" .  Could be sold in a nesting series of differing angles and depths.  This example also holds the 7 inch Balli Grid Spots (Balcar, Bowens, Speedotron, etc.)  In such use,  again the Ring becomes the universalizer.
 


DOUBLE RING ADAPTER for use when attachment of lightbank or other accessory proves too heavy for the reflector mount of a flashhead (usually only strong enough for a light weight reflector).  Note use of one of two threaded holes in the Ring.  Front Ring continues to allow the lightbank to rotate.



LIGHT PADDLE, a patented idea of  Don Farrall, for continually variable graduations inside a lightbank.  The idea could be extended to become a universal Barndoor / Reflector system outside  a softbox.
 
 


LOWEL "PADDLE" Adaptation.  With the addition of a small LOWEL clip to the Ring, any flash head  will be make compatible to the Lowel Flex  Arm System accessories.  Right photo:  All Lowel OmniLight accessories, such as the barndoor shown, would fit the "double" adapter spinning.
 
 

 
 


SPECIFIC FLASH ACCESSORY ADAPTERS, again the Ring could serve as a joiner between a flashhead of one brand and the accessories of another brand.  Shown here, Bowens to Elinchrom- just consider a Norman to Broncolor;  Speedotron to Comet; the brain soars and reels!


 

  FILTER FRAME, easily attaches coloured filters, NDs, metal scrims to the Ring for use within and out of a lightbank.  Frame reverses over the Ring during travel.  Pre-cut filter kit with the frame or only a template (or both).

 

 



  Other types of Lightbanks 


 
 

GRADUATED STILL LIFE LIGHTBOX measures 27 x 35 cm (11 x 14 inches).  Made from plastic "film" and silver fabric, this semi rigid design zippers open to fold flat.  Again,  the advent of digital is forcing the use of graduated light boxes to avoid the "blooming" of highlights.
 
 



 

ASYMMETRIC LIGHTBANK resulting in a 3:1 falloff from end to end.  Graduated lightbanks have long been the domain of less than a 1% of highest level of professional photographers, but, again, digital problems have brought this creative idea into the realm of necessity.
 
 



You saw it here first! Lighting Instruments

    Here are several configurations.  The first, a tungsten source that thinks it's a flash.  The second, a compact flash.  The last five are fluorescent instruments.

    In the future of imaging (still scanning, video and internet broadcast), there will be only one choice- Daylight balanced fluorescent.  Daylight balanced (4100-6500K) high frequency, high color (85+ CRI) fluorescent have the advantages of nearly equal  spectral Red, Green and Blue;  no spectral heat ( which distorts CCD response); and long lived lamps.   Incandescent sources have 92% spectral heat with little blue.  HMI / MSR lamps, though good RGB, have high UV and heat output, lamps are extremely short lived and very expensive to replace.



 

REMOTE TUNGSTEN WITH MODELLING  As tungsten is 92% heat, this fixture minimizes the energy  and heat during set-up and is turned on remotely (several fixtures at one moment) only during the imaging process, then turned off again to modelling level for continued set-up.  A two channel control would allow quarter, half and full stop ratio - that is, 250W modelling level (1/4), plus two 150 W "on" to total 550W (1/2), then four more 150W "on" to total  1150W (full).  All levels, due to multiple lamps, would be at full color temperature - not true with dimming methods.
 


INTERLOCKING "PENCIL LIGHT" 2400 w/s configuration with modeling and internal fan cooling.  Earlier product (on left) was designed six years ago by myself and Bill Farrall.  Bill produced it under the name "FlashStyx". Stolen by Photoflex's "hot" light.  The redesign on the right is 20% smaller, drawings and milled housing are completed.  Original thinking was that this design could accept all brands of flash accessories.
 

 


 

BABY FLO is a 30 Watt 6500K lamp with reflector (shown mounted to a Manfrotto table tripod).   Excellent Red, Green, Blue balance.   Cost retail could be $40 usd (w/o tripod).  Perfect for digital capture of jewelry and other  small product.  Several could be used with a Cocoon.


 

HIGH OUTPUT LIGHT BOX for digital capture of existing transparencies.  Such cameras as "BETTERLIGHT" and DICOMED Scan Backs can be further utilized to scan a photographer's existing collection of transparencies only IF a lightbox existed that concentrates the light.  This design  is an enlarger head on its side so that the heat escapes by convection out the back and only the heat-free daylight balanced 200 Watts of high frequency fluorescent passes out the transparency holder. Could be a Scandles accessory.



Studio and Location Products

Many product ideas come ONLY when working in the profession.  Some may be too esoteric for your consideration, but may serve to bring other viable possibilities to your mind.
 

STOWAWAY CAMERA BAG to solve the following problem—  over-the-shoulder bags are great during the "shoot",  not so great for protection during travel.  Conversely, hard cases, such as Pelican and Halliburton are great protection during travel, not so great during the "shoot".  This design folds flat (like a six pak carton of beer) to "stowaway" in the lid of a hard  case during  travel (replacing the usual foam liner), and opens up (like a six pak carton of beer) to hold cameras and lenses.


"Grippers" LIGHT WEIGHTS hold tight to the boom or lightstand due to their own weight pulling down on the special design of the closure.  This closure acts the same as a mountain climber's jumar ascender, jamming under the load of the climber and releasing when he shifts his weight to the other foot. Just the same, if you need to move the weight, you pick it up and slide it to it new position, where it lock again when you release it.
 
 


 

POWER DISK is a simple, easy-to-make, polycarbonate disk which will increase light output of a bare-bulb (Bron Pulso, Speedotron, Profoto, Comet) flash configuration by a stop or within a lightbox by 1/2 stop without change in light quality. Very cheap watt / seconds.



 

STILL LIFE FLASH SWITCH for "turning on and off" the several flash generators which a table top specialist might need between flash exposures for changes in focus, filters, movements and other special effects.  In this example, the three "on/off" switches are illuminated when "on", there is a "open flash" button and a sync cord receptacle.
