Description

[0001] The present invention relates to a COOLING FAN HAVING LED,

The disclosure relates to a cooling fan that is installed in a heated electronic device such as a computer to allow hot air to escape to allow the electronic device to operate normally.

Unless otherwise indicated herein, the contents set forth in this section are not prior art to the claims of this application and are not to be construed as prior art to be included in this section.

Generally, various electronic devices are provided with a heat dissipating device for emitting heat generated therein. That is, the heat dissipating device refers to a device installed on a heat-generating electronic component or installed in a case of an electronic device including an internal heat-generating electronic component to cause hot air to be radiated to the outside.

The conventional heat dissipating device includes a housing provided in the case, a driving motor fixed to the housing, and a fan connected to the driving motor to rotate. However, such a conventional heat dissipating device tends to have a relatively simple appearance. Therefore, in order to improve the monotonous appearance of the heat dissipating device, a heat dissipating device having a light emitting device mounted on one side of the light emitting device, mainly a fan, has been developed.

However, in the conventional heat dissipating device equipped with the light emitting element in the fan, it is difficult for the power supply line to be connected to the light emitting element. Therefore, the internal structure of the fan is inevitably complicated to realize this, and thus the manufacturing time and cost are increased.

In such a conventional heat dissipating device, there is a problem that the light emitting device fails or the entire fan needs to be replaced in order to realize a light emitting effect of a different color. In addition, there is a problem in that the emitted light is emitted to the outside as it is, and thus the user may be denied. In addition, there is a limit in that the light is not exposed to the outside because it is covered by a wall or a predetermined object depending on the direction in which the light emitting element is installed.

Brief Description of the Drawings The advantages and features of the disclosed subject matter, and how to accomplish them, will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. It is to be understood, however, that the disclosure is not limited to the embodiments set forth herein, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, But is provided only to fully disclose the scope of the disclosure to those with ordinary skill in the art, and the disclosure is only defined by the scope of the claims. Like numbers refer to like elements throughout.

The detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present disclosure. It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the invention as claimed. Therefore, the definition should be based on the contents throughout this specification.

Hereinafter, a cooling fan 1 having an LED according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3. FIG.

First, referring to FIG. 1, the main body 10 serves to rotate the fan 12 and operatively install the constituent members to be described later. The main body 10 is installed on the outer wall side of an electronic product such as a personal computer so that the hot air inside can be discharged to the outside. On one side, a drive motor is operatively installed to rotate the fan 12. [ In addition, ring-shaped fastening grooves 11 are formed at the edges thereof with upper and lower ends opened and both sides closed.

Referring to FIG. 2, an LED member 20 is rotatably installed in the above-described fastening groove 11. The LED member 20 is formed in a ring shape corresponding to the shape of the coupling groove 11 so that it can be positioned in the coupling groove 11, and a plurality of LEDs (Light Emitting Diodes)

Such LED member 20 may be manufactured in the form of a film or may be manufactured in the form of a flexible printed circuit board. Such a printed circuit board includes a plurality of conductive lines through which electrical signals can be transmitted on a base film, and includes a wiring pattern constituting a predetermined circuit and a connection portion connected to the outside.

The LED unit 20 may be used in a state in which it is electrically connected to an MCU (Micro Control Unit) whose blinking is controlled although not shown. The LED unit 20 may be turned on in one color by the MCU, or may be turned on or off at predetermined intervals. It is possible to effectively control the blinking of the LED 20 through the MCU as well as to operate at a relatively low voltage of 5V to 12V so that power consumption can be minimized.

On the other hand, the first ring member 30 is fastened to the upper end of the coupling groove 11 described above. The first ring member 30 serves to allow the light to be emitted to the outside when the LED member 20 is turned on. Therefore, it is made transparent or translucent so that light can be irradiated without being blocked, and is made of a flexible material. In addition, light emitted from the LED member 20 is made diffusible. For this, the first ring member 30 includes a material capable of diffusing light at the time of manufacturing, and includes at least one of the conventional optical diffusers.

The second ring member 40 is fastened to the lower end of the coupling groove 11 described above. The second ring member 40 serves to irradiate the light to the outside when the LED member 20 is turned on, like the first ring member 30 described above. 3, since the ring member is provided up to the lower end of the coupling groove 11 as well as the upper end of the coupling groove 11, light can be irradiated to the inside and outside of the electronic product when the LED member 20 is lit. Accordingly, it is preferable that the cooling fan 1 equipped with the LED according to the disclosure is applied to a case of an electronic product, for example, a case of a personal computer made of transparent or semi-transparent material.

That is, when the case of the electronic product is made of an opaque material, light may be irradiated only to the upper portion of the main body 10, that is, to the outside direction. However, It is useful to be surveyed. This is because the light irradiated to the upper portion of the main body 10, that is, the outside direction, can be blocked by the outer wall or the like in accordance with the direction in which the case of the electronic product is disposed. In this case, The light can be diffused outside the case of the electronic product, and the effect can be exerted.

The second ring member 40 is made of a flexible material such that the second ring member 40 is transparent or translucent so that the light can be irradiated without blocking the light. In addition, light emitted from the LED member 20 is made diffusible. To this end, the second ring member 40 includes a material capable of diffusing light during manufacture, and includes at least one of the conventional optical diffusers.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. But is not limited to the example.
