General
tips:
Energy can further be
saved by automating the light on / off process, (Control / Automation), after
selecting the right type of lighting device for a particular application,
Established devices
are photocells / occupancy sensors, these devices turn off street lights when
there is enough light measured by photocell or when vacant room is observed for
10 minutes or so. Almost all of street lights are switched through photocell
technology saving a lot of energy.
There are also
substantial leakages (from 20% to 100%) in energy through the people who manage
/ operate these devices, for example energy theft from public street lighting.
The solution is to leave street lighting to the individual person (gate lights)
rather than governments. We can save energy by using bigger devices
theoretically but substantial system leakages (theft) void all such
calculations.
Similarly larger power
plants are certainly more efficient technically, but public departments / and
large private companies are always in losses, because of loose control over a
large organization. Smaller energy generation units should also be promoted as
a means for efficiency by reducing taxes on sets / fuels.
Better management
procedures can also be utilized to minimize these losses, but can never be
avoided at all.
Beware!
Larger unit are
efficient technically but overall system efficiency fall remarkably,
distribution losses of 30% minimum reported, which are common throughout the
world. Hence smaller control units and smaller devices are recommended, for
example, street lights (150W to 400W) can be replaced with gate lights (mini
poles having LFT, 80 Watts). Similarly Revolutionary Grid-less Distribution (GD)
can saves billions of dollars, GD can be promoted by small generating sets,
less fuel taxes, less duties on small generating sets etc. GD also gives a
sense of independence which is priceless.
Marketing
Lighting control
devices manufacturers, and efficient lighting devices manufacturers should also
emphasis on the marketing to reach end consumer, in order to save energy.
Energy / incentives, competitions tax relaxes are only artificial means
promoting energy savings. It is just like someone awards a person for saving
some money. Energy saving means money saving it is self rewarding.
Such organizations are
simply a burden on the economy, which slows down the economy, when another tax
is imposed to finance these organizations. It does not mean that these
organization do not save energy, they save energy let say $ 10 but public have
to spend $100 on them to save $ 10, input is more than output.
Types
of Efficient Lighting Control
there are some type of motion detectors, which detect motion by means of
infrared, ultrasonic rays.
Some lighting
manufacturer also offer useful web programs to assist in lighting design such
as
Outdoor
lighting LED Payback Calculator Vs HID
There are also some other manufacturers of lighting products and
may have other similar or useful programmers, such as Philips and Osram.
