The latest innovation from RDS now presents
our Framelit SSL illuminated display panels with LED
solid state lighting in a satin chrome aluminium
frame.
The edge lit panels using low voltage LEDs
are powered through the cables suspending the frames*. No power
leads are visible. The low power use & extended reliability
ensures illumination of your message is at the lowest cost for
extended illumination. Image brightness & uniformity of
illumination cannot be matched.
With the window display it is now possible
to change media from behind the panel & recover the space lost
with front accessed light boxes with snap frames. Standard print,
single sided sale cards can be used on the
system.
Traditional lighting of window displays
rely on low voltage downlights fixed above each display column. To
enhance the illumination of the displays some have used a bottom
row of globes which is considered hazardous & doubles
the lighting costs.
Operational Costs
Based on the installation shown, running
the thirty six Framelit SSL panels, six hours per day over the
year the system will use 21.6 watts (only 0.6watts per
panel) x 2184 hours. At a power rate of $0.175 per KWH then
the operating cost would be $8.26 per annum (61.5kg of green
house gas emission). The LED light strip has an operating life of
between 30 - 50,000hrs or the equivalent of about 15 high quality
long life halogen globes.
If a conventional installation of
similar size (ie 36 x A3) had a single downlight per display
column, each would operate at 50 watts per fitting. Running costs
for twelve fittings would be 600watts x 2184 hours per annum. Again
a power cost of $0.175 per KWH would result in an annual operating
cost of $229.32 (1.76 tonne of green house gas emissions). Of
course if each panel used a downlight to achieve full illumination
then you would triple the operating cost.
Efficiency of
Illumination
Framelit SSL offers full face illumination of the
sale card image. Approximately 12% of the lighting power is lost
through the backing of the edgelit panel. Downlights by their
location can only illuminate a vertical face of the display. With
their light being produced in cone shape then only a small
percentage will be usable, a higher level of illumination being
provided to the top display row with dimishing values to the lower
display panels.
