(2) background technique

Although industry such as semiconductor, biotechnology at the top of one's power and career, if but lack the cooperation of some relevant traditional facilities, even beautiful its high-tech by name, still may be lack scope for their abilities, the most significant example is no more than the relation of computer and radiation fan, and computer related industry one is to being regarded as high-tech, but during actual operation, the power supply unit of computer partly needs fan to dispel the heat, and as the central processing unit (CPU) of computer heart, the fan of heat transmission can not lack especially.Therefore, although be traditional product, on significance, still can not despise.

With aforesaid radiation fan is example, and the product in past is conceived to its heat sinking function mostly, there is no on outward appearance or other auxiliary functions and puts forth effort.Therefore, the being seen radiation fan of common people, its framework (FRAME) and flabellum part is the engineering plastics injection moulding by black mostly, so from appearance, traditional radiation fan there is no considerable part with generally the pure function industrial products are identical.

Yet, for winning Consumer's favor,, also wish the consumer group that can expand different aspects through the change of outward appearance appearance even win victory with function, as present existing on the market computer chassis, its appearance variation and aesthetic measure all have remarkable enhancement compared to computer chassis in the past.Under this situation, aforesaid radiation fan seemingly has improved space and demand in appearance, yet be subject to its function and purposes, its basic shape has its immutableness, and under the restriction that basic shape should not change, make radiation fan on visual effect, have breakthrough as desire, promptly remain further to be thought deeply its feasible program.

(3) model utility content

Therefore, the utility model main purpose is to provide a kind of fan that utilizes light to strengthen visual effect, and it cooperates the variation of fan color, can produce synchronous or asynchronous dynamic light effect in the flabellum operating frequency when flabellum turns round.

For realizing that the major technique means that aforementioned purpose is taked are to be provided with a base in the place, axle center of a framework, base is provided with a circuit board, has stator on the circuit board, is combined with the flabellum group on the stator relatively; Wherein:

This frame inner wall is formed with more than one mounting hole, is provided with light emitting diode in the mounting hole;

When the light of light emitting diode is invested flabellum group and the entry into service of flabellum group, can produce and dazzle beautiful in riotous profusion dynamic optical image effect.

Aforementioned light emitting diode is by fan drive circuit synchronous drive set on the circuit board.

Aforementioned light emitting diode is the control circuit driving by the outside.

Aforesaid frame and flabellum group are to be made of the perspex material.

Aforementioned light emitting diode is the colorful light-emitting diode.

For further specifying the purpose of this utility model, structural feature and effect, the utility model is described in detail below with reference to accompanying drawing.

(5) embodiment

Relevant structure division of the present utility model, see also shown in Fig. 1,2, mainly be to be formed with a base 11 in the place, axle center of a rectangular hollow framework 10, base 11 is provided with a circuit board 20, has stator 21 on this circuit board 20, be combined with flabellum group 30 on the stator 21 relatively, wherein flabellum group 30 inboards are provided with annular permanent 31, can form mutual exclusion with the magnetic pole of changed polarity on the stator 21 with rotary driving; In addition, identical with the traditional heat-dissipating fan, aforesaid frame 10 is to be made of plastic material, but consider that its basic shape is limited, it gives the demand of the different visual effects of people and still have breakthrough, so can on the color of plastic material and physical property (as transparent or semitransparent), be adjusted, for example use can produce the colorful light-emitting diode arrange in pairs or groups transparent or semitransparent framework 10 constitute the light refraction effect, to produce totally different special visual effect in existing radiation fan.

For realizing aforementioned purpose,, be formed with more than one mounting hole 12 on the madial wall of hollow part, and in mounting hole 12, be provided with light emitting diode 13 (please cooperate shown in Fig. 3,4) except that framework 10 is made of colored or transparent, translucent plastic material; Wherein, this mounting hole 12 has a gradient with respect to framework 10 axle center, when framework 10 is when being made of transparent or semitransparent material, light emitting diode 13 in its mounting hole 12 is except that to the throw light of the hollow part of framework 10, also reflect repeatedly, and present transparent sparkling and crystal-clear visual effect along mounting hole 12 hole walls.

The control mode of relevant aforementioned light emitting diode 13, it can be by fan drive circuit institute synchronous drive set on the aforementioned circuit plate 20, one feasible circuit structure as shown in Figure 5, mainly be by two output terminals of a drive integrated circult (IC) 22 respectively with two groups of coil L1 of stator 21, L2 connects, so that two groups of coil L1, L2 alternate conduction and produce the magnetic pole of opposed polarity, under this circuit framework, be to make light emitting diode 13 and aforementioned drive IC 22 and coil L1, the L2 common source, in other words, when power supply is sent into drive IC 22, remove by drive IC 22 driven coil L1, the L2 conducting, so that outside 30 rotations of flabellum group, light emitting diode 13 also will be lighted simultaneously, and keeps permanent bright.

In addition, though aforementioned light emitting diode 13 and drive IC 22 common sources, but its rotating speed of lighting with flabellum group 30 there is no any relation, as desire to make light emitting diode 13 to be the flicker shape with the rotation speed change situation of flabellum group 30, then can adopt fan drive circuit as shown in Figure 6, this fan drive circuit removes still and drives two groups of coil L1 by drive IC 22, outside the L2, this drive IC 22 is connected with each light emitting diode 13 by a flicker control circuit 23 with one frequency output connecting pin, wherein, this flicker control circuit 23 comprises a transistor T R, an one counter U2 and a decoder U1 (DECODE), when drive IC 22 entrys into service, its output connecting pin produces a pulse signal by transistor T R to counter U2, by producing a carry pulse after the counter U2 processing and sending and give decoder U1, decipher 13 flickers of the set light emitting diode of its output terminal of rear driving by decoder U1.Whereby, flicker control circuit 23 can be simultaneously drives the frequency scintillation of each light emitting diode 13 with correspondence according to the rotating speed of drive IC 22, to make the richer variability of lighting effects on the radiation fan with this design, and can provide more dazzling visual effect, except that the construction of visual effect, aforementioned circuit also can cooperate light emitting diode 13 that warning effect is provided when fan locks.

Aforementioned two embodiments' fan drive circuit is to be located on the circuit board of radiation fan, and in addition, the driving of relevant light emitting diode also can utilize external circuit to control.

Can find out concrete structure kenel of the present utility model and working principle thereof by above-mentioned explanation, can make originally dull with this design, even breakthrough change appears in stiff dull industrial radiation fan in appearance, thereby can present totally different in visual effect previously, in addition, through cooperating the circuit design of particular design, can beyond lighting effects, provide the fan failure alarm function, when making fan apply to the heat sinking function of CPU, guaranteed the Security of CPU.Certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claims the above embodiment's variation, modification.
