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

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

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.

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.

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.

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.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIGS. 1 through 5, the illuminant electric fan is mainly composed of a [0013] 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.
The [0014] 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.
In addition, the [0015] 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.
As shown in FIG. 2, there are several sets of [0016] 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.
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. [0017]
