Sunzhou Technology is based on newly developed technologies to
deliver the outstanding performance of decorative lighting and
traffic lighting for no-maintenance, no-energy-cost,
semi-permanent product life span. SolarCap adopted
"Solid-State Lighting" technology to achieve the best
performance for decorative and traffic lighting with the least
efforts and money. The major components are solar cells, LED,
and ultracapacitor.

Solid State Lighting
|
|
| |
Lighting applications that use Light Emitting Diodes (LEDs) are
commonly referred to as Solid-State Lighting. Major benefits of
solid-state lighting systems include: ● Long life - reduced
maintenance cost ● Reduced energy consumption - especially
when colored light is needed ● Better quality light output -
minimum ultraviolet (UV) and infrared (IR) radiation ●
Intrinsically safe - low voltage ● Smaller flexible light
fixtures - useful for lighting tight spaces ● Durable - no
filament to break.

Solar Cells (Photovoltaics)
|
|
| |
| Solar cells
convert sunlight directly into electricity. Solar cells
are the one that are often used to power calculators and
watches. Solar cells are made of semiconducting
materials similar to those used in computer chips. When
sunlight is absorbed by these materials, the solar
energy knocks electrons loose from their atoms, allowing
the electrons to flow through the material to produce
electricity. This process of converting light (photons)
to electricity (voltage) is called the photovoltaic
effect. The performance of a PV cell is measured in
terms of its efficiency at turning sunlight into
electricity. Only sunlight of certain energies will work
efficiently to create electricity, and much of it is
reflected or absorbed by the material that make up the
cell. |

LED
|
|
| |
The LED (Light Emitting Diode) is basically a really
fancy diode. Diodes only let current (electricity) to flow in
one direction and not the other. LEDs are diodes too, but they
have the unique "side effect" of producing light while
electricity is flowing through them. LEDs are different from
ordinary light bulbs because they do not have a filament to
break or burn out. They operate on very low voltage from 2-3
volts, generate very little heat, and are ideal for putting
lights into portable equipments and self-contained solar
lighting devices. In the simplest terms, an LED is made with two
different kinds of semiconductor material: one type that has too
many free electrons roaming around inside, and another that
doesn't have enough. When an electron from one material (the
donor) gets pushed across a thin barrier and gets into tiny
spaces in the other (the holes), a photon or particle of light
is produced. The color of light depends on a number of factors,
including the type of material they make the LED with and the
material's quantum bandgap (how much energy each electron needs
to pack in order to cross the barrier). A smaller bandgap that
fairly weak electrons can cross gives you infrared or red light,
while a large bandgap that needs really strong electrons gives
you light that has a blue or violet color to it.

Ultracapacitor
|
|
| |
| Ultracapacitor is a newly
developed technology positioned between the conventional
capacitors and the rechargeable batteries.
Ultracapacitors offer a shift in thought, circumventing
the battery scramble, and instead attempt to elicit
greater efficiency from existing power sources.
Ultracapacitors are free from the characteristic battery
problems of limited cycle life, cold intolerance, and
critical charging rates. It is also environmentally
friendly, helps conserve energy, and enhances the
performance and portability of consumer devices.
Ultracapacitors can replace batteries in outdoor
solar-lighting products. Although its energy less
compared to a battery, it's enough to light up the
garden, drive away, garden path or any place. The
ultracapacitor is much well suited over batteries in
solar lighting products: Because an ultracapacitor
transfers electrical charges between conducting
materials, it can be charged and discharged almost
indefinitely, which lead to remove annoying maintenance
problem, whereas few batteries, using chemical
reactions, can last 1000 cycles. In addition, the
ultracapacitor can also be charged effectively
regardless of weather condition. |
