8.4 Mechanisms and Systems
The mechanism of this product, including external dimensions, is almost the same as
that of the LV7215.
●
Lowering Temperature and Reducing Noise
To control temperature, this product has adopted the following features: enlargement
of the punching diameter of the ventilation port, changing the lamp duct, changing
the fixture that anchors the ventilation fan, and changing the power source holder.
These improvements make it possible to reduce the number of fan revolutions and
lower the level of fan noise.
Also, in addition the reduction in the number of fan revolutions mentioned above, a
himelon sheet is spread in the interior to baffle spurious noise from the front, and
cushions have been added near the ventilation ports on the sides to suppress
vibrations.
Compared to the current mode (LV-7215), this product achieves a reduction in
spurious noise of approximately 1.5 dB when operating in the Lamp Normal mode.
8.5 Design
(Same as LV-7215/7210/5210 except for the underlined part)
These projectors continue the design concepts of Canon's power-projector series: an
intelligent and beautiful appearance; a solid three-dimensional form refined to the finest
detail; and the look and feel of an optical instrument. Canon's designers also aimed for a
next-generation standard of simplicity and transparency that creates an approachable
and agile impression.
●
Styling
These products were styled to suit a variety of situations: from private living rooms to
office environments particular about interior design and retail stores where projectors
are used for promotional purposes.
The main unit employs an "air-style form", featuring a clean surface construction and
simple molded elements that blend naturally into the installation space. The
translucent operation panel, fashioned in the shape of a jellybean, accentuates the
overall style. Also, attention was paid to the surface finish and key layout so that
users can find their way around the operation panel just by touch in low-light
situations.
●
Color scheme
Not used for the conventional models, Frosty White Pearl, the new body color,
engenders feelings of high quality and transparency.
* The initial LV-7215 models were given a double coat of paint. However, to simplify
the manufacturing process and reduce costs, later models were given a single coat,
giving them a different look.
Like the LV-7215, a later model, this product was also given a single coat.
