Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an office building or a
base station house, and in particular to an office building or a
base station house capable of regulating indoor temperature and
lighting by making use of the thin film solar cells in achieving
energy conservation.
[0003] 2. The Prior Arts
[0004] Along with the global concern about environment protection,
and worldwide acceptance and implementation of the concept of
"energy conservation and carbon reduction", therefore, the
development and utilization of regenerated energy resources has
been the keypoint of development for various countries of the
world. Among the regenerated energy resources, solar energy and
solar cell capable of converting sunlight into electrical energy
are of the most promising energy industry, since sunlight is
available all over the world, and it would not create pollution to
the Earth like other energy resources (such as nuclear energy,
petrochemical energy).
[0005] In case that the solar cell is provided with a large light
irradiating area, then it can produce relatively large amount of
electrical energy for use by various devices. Therefore, quite a
lot of manufacturers hope to incorporate the energy saving concept
into daily life of ordinary people, such as utilizing reusable
solar cell in replacing the conventional disposable battery cells,
so as to reduce pollution to the environment. In addition, the
concept of "green energy building" can be combined with the solar
cell, namely, putting solar cells in a building, where they are
most exposed and irradiated by sunlight, such that the electrical
energy generated by solar cell can be used to compensate for the
electrical energy consumed by the building.
[0006] Presently, solar energy is most needed for agricultural
green house and machine rooms of communication servers where
constant temperatures are required, and in this respect, the
conventional solar cell has much room for improvement.
SUMMARY OF THE INVENTION
[0007] In view of the problems and shortcomings of the prior art,
the present invention provides an office building or base station
house, where on the top portion of the building body is provided
with thin film solar cells, for achieving the effects of lighting,
energy saving, and temperature regulation.
[0008] The present invention provides an office building having
transparent top portion, the office building is disposed on the top
portion of a higher and bigger building. The office building
includes a building body, and at least a thin film solar cell. The
building body has a top portion, and the thin film solar cell is
arranged on the top portion. In operations, the thin film solar
cell absorbs green light, blue light and ultraviolet light and
converts them into electrical energy, and it reflects a part of the
infrared light and ultraviolet light that can not be absorbed; the
red light, orange light, and yellow light pass through the thin
film solar cells and reach inside the building body to provide the
illumination required.
[0009] In an embodiment of the present invention, the thin film
solar cell mentioned above is a kind of transparent solar cell,
that can be used as building material for the top portion of the
building body, so as to provide illumination when the sunlight is
sufficient.
[0010] In another embodiment of the present invention, the building
body can be an office room, a communication machine room, or a base
station house.
[0011] In yet another embodiment of the present invention, the
office building further includes a plurality of
light-emitting-diodes (LEDs), arranged at the top portion of the
building body, for providing illumination light beams irradiating
inside the building body. The thin film solar cells are connected
electrically to the LEDs, so as to supply the converted electrical
energy to LEDs as required.
[0012] In another aspect of the present invention, the present
invention provides a base station house having thin film solar
cells, comprising a building body, at least a thin film solar cell,
and a power source module. The base station house can be located on
top of a higher and bigger building, the building body is provided
with a top portion, and the thin film solar cell is disposed on the
top portion of the building body. In operations, the thin film
solar cell absorbs green light, blue light and ultraviolet light
and converts them into electrical energy, and it reflects a part of
the infrared light and ultraviolet light that can not be absorbed;
the red light, orange light, and yellow light are transmitted to
inside of the building body through the thin film solar cells, thus
providing the indoor illumination required. The power source module
is located inside the building body for storing the electrical
energy converted by the thin film solar cell, and supplying the
electrical energy to the communication equipment in the base
station house as required.
[0013] In a further embodiment of the present invention, the top
portion of the building body can be a detachable and replaceable
roof structure, such that thin film solar cells can easily be
replaced.
[0014] In a yet another embodiment of the present invention, the
power source module includes a power supply device and a power
storage device. The power storage device is used to store the
electricity supplied by the power supply device and the electricity
converted by the thin film solar cells, and supply the electricity
to the base station house. In the present embodiment, the power
storage device can be an uninterrupted power supply (UPS), and the
power supply device can be a diesel fuel generator
[0015] In a still another embodiment of the present invention, the
base station house may further include an air conditioner disposed
in the building body, and it regulates the temperature inside the
sentry-box-shaped building body, with its power supplied by the
power source module.
[0016] In a further embodiment of the present invention, the base
station house may further includes a plurality of
light-emitting-diodes (LEDs) placed on the top portion of the
sentry-box-shaped building body, that is used to provide
illumination at night or when the illumination in the building is
insufficient. The LEDs are connected electrically to the thin film
solar cell, and are powered by the thin film solar cells.
[0017] As mentioned above, in the embodiment of the present
invention, in the office building or base station house, thin film
solar cells are arranged on top portion of building body, so that
when irradiated by sunlight, the thin film solar cell absorbs the
green light, blue light, and ultra-violet light contained therein,
and converts them into electrical energy, for supplying it to the
power storage device, air conditioner, or communication equipments
in the office building, thus saving the expense spent on
electricity. In addition, the red light, orange light, yellow
light, and infrared light will pass through the thin film solar
cell and reach inside of the building body in providing
illumination to the office building. Since some of the infrared
light and ultraviolet light are reflected by the thin film solar
cell, the rate of temperature increase inside the base station
house can be reduced, thus the internal temperature can be
regulated effectively in cooperation with air conditioners, hereby
saving expense of electricity for the air conditioner. Furthermore,
the present invention also provides a base station house based on
the above mentioned concept.
[0018] Further scope of the applicability of the present invention
will become apparent from the detailed description given
hereinafter. However, it should be understood that the detailed
description and specific examples, while indicating preferred
embodiments of the present invention, are given by way of
illustration only, since various changes and modifications within
the spirit and scope of the present invention will become apparent
to those skilled in the art from this detailed description.
BRIEF DESCRIPTION OF THE DRAWINGS
[0019] The related drawings in connection with the detailed
description of the present invention to be made later are described
briefly as follows, in which:
[0020] FIG. 1 is a schematic diagram of office building having thin
film solar cells according to a first embodiment of the present
invention; and
[0021] FIG. 2 is a schematic diagram of office building having thin
film solar cells according to a second embodiment of the present
invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0022] The purpose, construction, features, functions and
advantages of the present invention can be appreciated and
understood more thoroughly through the following detailed
description with reference to the attached drawings. And, in the
following, various embodiments are described in explaining the
technical characteristics of the present invention.
[0023] Refer to FIG. 1 form schematic diagram of office building
having thin film solar cell according to a first embodiment of the
present invention. As shown in FIG. 1, the office building 100
comprises a building body 110 and at least a thin film solar cell
130. In the present embodiment, the building body 110 of the office
building 100 can serves as an office room, a communication machine
room, or a base station house, for the purpose of sheltering and
protecting communication equipment 105 in the building body 110,
and accommodating several operation personnel (not shown) to
perform routine operations and maintenance as required. In some
embodiments, communication equipment 105 includes wireless
communication equipment, such as a large or medium size wireless
base station, signal bridge, large signal transceiver (for example
large directional antenna), etc.; or wire communication equipment,
such as network address router, router, bridge, communication
server, or optical fiber signal converter, etc.
[0024] As such, the building body 110 is provided with a top
portion 120, and thin film solar cells 130 is disposed therein. To
be more specific, in the present embodiment, the major
characteristic of the thin film solar cells 130 is that, when
sunlight L1 irradiates onto the top portion 120 of the
sentry-box-shaped building body 110, the thin film solar cells 130
on the top portion 120 will absorb the green light, blue light, and
ultraviolet light in sunlight L1 and converts them into electrical
energy. In addition, the thin film solar cells 130 will reflect
part of the infrared light and ultraviolet light that are not
absorbed, such that the temperature inside the building body 110 is
not apt to increase, so as to make it cooler and comfortable. Red
light, yellow light, and yellow light in the sunlight L1 pass
through the thin film solar cell 130 and reach inside of the
building body 110 (dashed lines L1 as shown in FIG. 1), thus
providing indoor illumination when the intensity of sunlight L1 is
sufficient. In other words, in the present embodiment, the thin
film solar cell 120 can be a transparent solar cell, such that red
light, orange light, yellow light, and infrared light in sunlight
L1 are apt to pass through the thin film solar cells 130, yet green
light, blue light, and ultraviolet light in sunlight L1 are apt to
be absorbed or reflected by the thin film solar cells 130.
[0025] In the present embodiment, the office building 100 may
further includes a power source module 150, used for storing the
electricity as converted and obtained by the thin film solar cells
130, and supplying the electricity to the communication equipment
105, air conditioner 170, or other electrical/mechanical devices in
the office building 100. Since the electrical energy converted and
obtained through the thin film solar cells 130 may offset or
compensate a part of ordinary power consumption of the office
building, thus it can save electricity expense. When there is
surplus of this kind of converted electrical energy, power source
module 150 may feedback the electricity and supply it to the power
network or the Power Company, so as to earn some additional
revenue.
[0026] In the present embodiment, the power source module 150 can
be an uninterrupted power supply (UPS), and is connected
electrically to a power supply socket; meanwhile, it may also store
the electrical energy converted by the thin film solar cells 130
for supplying it to the wireless communication base station.
Moreover, office building 100 may also include power supply device
155 (in the present embodiment, a diesel-fuel generator are taken
as an example), so that when the power supply is interrupted, the
power supply device 155 can be activated immediately to supply the
power required, so as to maintain the normal operations of the
communication equipment 105.
[0027] Furthermore, in the present embodiment, some of the
equipment in the office building 100 can not maintain normal
operations in high temperature, for example, communication
equipment 105, uninterrupted power supply (UPS) 150, and power
supply device 155. Therefore, in an office building 100, an air
conditioner 170 is required to regulate room temperature, and that
is located in a sentry-box-shaped building body 110 in regulating
its inner temperature, and in cooperation with the functions of
thin film solar cells 130 of reflecting part of the infrared light
and ultraviolet light, temperature in the building body 110 can be
maintained at a lower temperature. In this respect, power source
module 150 and the thin film solar cells 130 may supply power to
the air conditioner 170, so as to save air conditioning expense on
electricity.
[0028] In the present embodiment, the top portion 120 of the
building body 110 can be a detachable and replaceable structure,
such that it is easy to replace any damaged or worn out thin film
solar cells 130. In addition, the entire structure of office
building 100 can be designed into a modular configuration similar
to a kind of container house, so as to facilitate the assembly,
installation, and transportation of communication equipment 105.
Moreover, the office building 100 is also provided with a plurality
of light-emitting-diodes 160 for illumination at night. To be more
specific, the light-emitting-diodes 160 are arranged on the top
portion of the building body 110, such that when in sunny weather
and broad daylight, the portion of sunlight L1 passing through the
transparent thin film solar cells 130 can be used for internal
illumination of a sentry-box-shaped building body 110; and while in
cloudy weather or at night, light-emitting-diodes 160 can replace
light bulbs in providing sufficient illumination inside the
building body 110, so that maintenance staff may carry on repair
and/or maintenance of communication equipment 105 at night.
[0029] Furthermore, thin film solar cells 130 may also be connected
electrically to the light-emitting-diodes 160 for providing them
with the converted electricity. To be more specific, when in sunny
weather and broad daylight, the portion of sunlight L1 passing
through the thin film solar cells 130 can provide illumination
inside the building body 110; and while in cloudy weather or at
night, light-emitting-diodes 160 can provide sufficient
illumination inside the building body 110, with its power provided
by ordinary local power supply, in addition, the power stored in
power source module 150 mentioned above can also be utilized, so as
to save the local power supply utilized, in achieving "energy
conservation and carbon reduction".
[0030] It is worth mentioning that, in another embodiment of the
present invention, the thin film solar cells 130 can be made into
eaves on the top portion 120 of the office body 110, also thin film
solar cells 130 can be placed on outer wall of the office body 110
to increase the receiving area of sunlight L1. Refer to FIG. 2 for
a schematic diagram of office building having thin film solar cells
according to a second embodiment of the present invention. As shown
in FIG. 2, the top portion 120 of the office body 110 is extended
outward into an eaves portion 210, that is made of thin film solar
cells 130 so as to increase light receiving area and photoelectric
conversion efficiency, moreover, it can also provide shelter
against rains and strong winds. In addition, in the present
embodiment, the outside walls 220 around the office body 110 are
provided with thin film solar cells 130 (as shown by slant line in
FIG. 2), so as to increase the light receiving area, and the
photoelectric conversion efficiency of the thin film solar cells
130.
[0031] Summing up the above, in the present invention, thin film
solar cells are provided on the top portion of a building body,
such that when sunlight irradiates on the top portion of the
building body, the thin film solar cells absorb the green light,
blue light, and ultraviolet light in the sunlight, and convert them
into electrical energy, and then provide it to the power storage
device, air conditioner, or communication equipment, etc, in the
office building, so as to save expense spent on electricity; while
red light, orange light, yellow light, and infrared light will pass
through the thin film solar cell, and reach inside the building
body for indoor illumination of the office building. Since some of
the infrared light and ultraviolet light are reflected by the thin
film solar cell, the rate of temperature increase inside the base
station house can be reduced, thus the internal temperature can be
regulated effectively in cooperation with an air conditioner,
hereby saving expense of electricity for the air conditioner.
Furthermore, the present invention also provides a base station
house based on the concept mentioned above.
[0032] The above detailed description of the preferred embodiment
is intended to describe more clearly the characteristics and spirit
of the present invention. However, the preferred embodiments
disclosed above are not intended to be any restrictions to the
scope of the present invention. Conversely, its purpose is to
include the various changes and equivalent arrangements which are
within the scope of the appended claims.
