Illuminant Electric fan
Abstract
An illuminant electric fan mainly comprises a base frame, a fan
blade assembly and a plurality of LED lamps, in which the fan blade
of the fan blade assembly is mounted and rotates in the tunnel
bracket of the base frame to achieve air convection and heat
dissipation. The fan blade is made of the luminous material to
affect the luminance. Around the rim of the fan tunnel is decorated
with a plurality of insert holes to be filled with the LED lamps
too. The LED lamps are linked in series to a PCB, which serves the
power supply and control over the rotation of the electric fan
blade and the lighting of the LED lamps. The light beam emitted
from the LED lamp will refract and radiate to produce a wonderful
vision.

Description
BACKGROUND OF THE INVENTION
[0001] The prior art of the electric fan simply works for heat
dissipation. It presents a monotonous and rigid appearance with no
diverse colors; that is to say, it does not take advantages of the
technological advances to promote life quality and make the
environment more colorful and joyful. Taking advantages of the
technological advance to promote life quality and make the
environment more colorful is the key purpose of this invention. In
additional to heat dissipation, the electric fan the inventor
intends to develop has substantial added value, powerful
competitive edge, attractive luminescence and wonderful vision.
SUMMARY OF THE INVENTION
[0002] The main object of the invention is to provide an illuminant
electric fan, on the rim of the fan tunnel is provided with insert
holes to be filled with a string of LED lamps in series connection.
When the rotation of the fan blade generates a convectional airflow
to effectively dissipate the heat around, in the meantime, the fan
blade refracts the light beam emitted from the LED lamps to from a
wonderful vision, which certainly increases the added value and
competition.
[0003] Another object of the invention is to provide an illuminant
electric fan which has a common circuit lining the LED lamps string
and the fan blade assembly in series in which the LED lamp circuit
serves as a detective circuit for the fan blade assembly, easy for
repair work.
[0004] Another object of the invention is to provide the base frame
of the electric fan with a CPU controller which controls the
centrifugal fan blade and enhance the convectional flow.
[0005] The special features and the structure of the illuminant
electric fan of the invention are explained in great details with
the aid of the preferable embodiment as illustrated in the attached
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS

together.
[0012] FIG. 7 shows an embodiment of another illuminant electric
fan of the invention.
DETAILED DESCRIPTION OF THE INVENTION
[0013] As shown in FIGS. 1 through 5, the illuminant electric fan
is mainly composed of a base frame 1, a fan blade assembly 2 and a
plurality of LED lamps 3. Where the axle of the fan blade 21 of the
fan blade assembly 2 is fastened in the center recess 111 of the
fan tunnel 11 of the base frame 1, permitting the fan blade 21 to
rotate in the hollow tunnel 12. While the fan blade 21 is running,
the airflow comes from one side and goes out at other side as shown
in FIG. 3 and dispels heat away. The fan blade 21 can be made of
luminous material and it emits luminescence while in rotation.
[0014] The hollow tunnel 12 provides a plurality of insert holes
121. As shown in FIGS. 2 and 4, there are four insert holes 121
illustrated and each insert hole is filled with an LED lamp 3.
These four LED lamps are linked in series with a wire on the PCB
31. The wire on the PCB 31 further links in series with a power
wire 22 of the fan blade assembly 2. When the fan blade assembly 2
is powered, the fan blade 21 produces convectional airflow to
dispel heat, the power further lights the LED lamps on the hollow
tunnel 12 of the base frame 1, as shown in FIG. 3. This design
performs to dispel heat and promotes powerful competition.
[0015] In addition, the LED lamps 3 and the fan blade assembly 2
share jointly a common circuit where the lighting of the LED lamp 3
can serve as s sensor to see good conductivity of power wire 22
linked to the fan blade assembly 2. It is another performance the
LED lamp 3 provides.
[0016] As shown in FIG. 2, there are several sets of lock holes 13
on the base frame 1. The inner lock holes 13 are employed to lock
up the centrifugal fan blade assembly. The outer lock holes 13 are
used to install a CPU-controlled fan blade assembly 4 as shown FIG.
6 to reinforce the convectional airflow. As shown in FIG. 7, the
LED lamp 3 is disposed on the circuit board 23 of the fan blade
assembly 2, which causes the light beam flashing among the gap of
the fan blade 21 to generate another imaginary vision.
[0017] View from the above statement, the illuminant electric fan
achieves twofold purposes: to dissipate heat and produce a
wonderful vision, so it is really a novel and practicable
invention.
