Description
本發明係關於一種風扇模組，特別是一種具有光源的風扇模組。The invention relates to a fan module, in particular to a fan module with a light source.
隨著電子產業的快速發展，使電子裝置中電子元件的運算速度大幅度提高。然而，隨著運算速度的增加，往往造成電子產品中用以執行資料運算的中央處理器(central processing unit，CPU)或圖形處理器(graphic processing unit，GPU)等電子元件產生大量的廢熱。此時，若無法即時的將這些廢熱從電子產品中排放，將容易導致電子元件的運作溫度過高，而造成其運算速度大幅降低，並嚴重影響電子產品的運作效能及穩定度；或者是，造成電子元件無法承受高溫而燒毀的情形發生。With the rapid development of the electronics industry, the computing speed of electronic components in electronic devices has been greatly improved. However, as the speed of operation increases, electronic components such as a central processing unit (CPU) or a graphics processing unit (GPU) for performing data operations in an electronic product often generate a large amount of waste heat. At this time, if the waste heat cannot be discharged from the electronic product in an instant, the operating temperature of the electronic component is likely to be too high, which causes the calculation speed to be greatly reduced, and the operational efficiency and stability of the electronic product are seriously affected; or Causes that electronic components cannot withstand high temperatures and burn out.
針對此一問題，目前常見的散熱方式之一，是在電子產品上設置風扇，用以對電子產品內的電子元件進行散熱。其主要是利用風扇所產生的空氣氣流吹拂於電子元件上，藉以在電子元件表面進行熱交換作用。One of the common heat dissipation methods for this problem is to provide a fan on the electronic product for dissipating heat from the electronic components in the electronic product. It mainly uses the air flow generated by the fan to blow on the electronic component, thereby performing heat exchange on the surface of the electronic component.
傳統應用在電子裝置的風扇，其功能大多著眼於散熱功能上，使風扇的外觀設計變化不大，並且不具其他的附加功能，因此另有業者開發出具有光影效果的發光風扇，藉以吸引消費者的目光及選用。一般發光風扇主要包含一扇框、一扇輪以及單一或複數個發光元件，例如發光二極體(light emitting diode，LED)，其中扇輪可旋轉的設置在扇框內，發光元件則設置在扇框或扇輪上。並且，為了讓發光元件發射的光線具有較好的照明效果，當發光元件設置在扇框時，通常將發光元件的發光方向朝向扇輪；以及當發光元件設置在扇輪時，將發光元件的發光方向沿平行於扇輪軸向的方式設置。因此，當發光風扇接收外部電源而產生運轉時，可藉由發光元件的明暗變化來產生炫麗的燈光效果。Conventionally applied to the fan of an electronic device, its functions mostly focus on the heat dissipation function, so that the design of the fan does not change much, and there is no other additional function, so another industry has developed a light-emitting fan with light and shadow effect, thereby attracting consumers. Eyes and choices. A general light-emitting fan mainly comprises a frame, a fan wheel and a single or a plurality of light-emitting elements, such as a light emitting diode (LED), wherein the fan wheel is rotatably disposed in the fan frame, and the light-emitting element is disposed at On the fan frame or on the fan wheel. Moreover, in order to make the light emitted by the light-emitting element have a better illumination effect, when the light-emitting element is disposed in the fan frame, the light-emitting direction of the light-emitting element is generally directed toward the fan wheel; and when the light-emitting element is disposed on the fan wheel, the light-emitting element is The direction of illumination is set parallel to the axial direction of the fan wheel. Therefore, when the illuminating fan receives an external power source to generate operation, a bright lighting effect can be produced by the brightness change of the illuminating element.
然而，前述發光元件的設置方式，由於是固定在扇框上，因此只能呈現出靜態的燈光變化效果，例如光線的明暗與色彩的變化等；另外，將發光元件固定在扇輪的設置方式，由於發光元件的發光方向平行於扇輪軸向，即發光元件沿著扇輪軸向發射光線至外界環境，因此，在實際應用上，無論使用者是直視於發光風扇觀賞其燈光效果，或者是在發光風扇周圍使用電子裝置時，使用者的眼部都極易受到發光元件所產生光線的照射、刺激，而造成使用者的眼部不適，進而嚴重影響使用者採用發光風扇的意願。此外，由於發光風扇的發光元件只能單純提供光線的明暗變化來吸引使用者的目光，但是並無法提供使用者發光風扇的其他運作資訊，例如當前風扇運轉時的工作溫度或運轉速度等相關資訊，因此目前發光風扇在應用上的實用性仍有待進一步的提升。However, since the arrangement of the foregoing light-emitting elements is fixed on the fan frame, only static light change effects, such as light and darkness of the light and color changes, and the like, and the manner in which the light-emitting elements are fixed to the fan wheel are provided. Since the light-emitting direction of the light-emitting element is parallel to the axial direction of the fan wheel, that is, the light-emitting element emits light along the axial direction of the fan wheel to the external environment, in practical applications, whether the user directly views the light-emitting fan to view the light effect, or When an electronic device is used around the illuminating fan, the user's eyes are highly susceptible to the illumination and stimulation of the light generated by the illuminating element, which causes the user's eye discomfort, which seriously affects the user's willingness to use the illuminating fan. In addition, since the illuminating element of the illuminating fan can only provide the light and dark changes of the light to attract the user's gaze, it does not provide other operational information of the user's illuminating fan, such as the current operating temperature or operating speed of the fan during operation. Therefore, the practicality of the current lighting fan in application still needs further improvement.
鑒於以上的問題，本發明在於提供一種風扇模組，藉以解決習用風扇只具有散熱功能，但無法讓使用者得知風扇運轉效能的相關資訊的問題，以及習用發光風扇只能提供單純的燈光明暗變化，其同樣無法提供使用者有關風扇運轉效能的相關資訊，以及在使用上，使用者的眼部容易受到發光風扇的發光元件照射，而嚴重影響使用者在操作電子裝置時的舒適性的問題。In view of the above problems, the present invention provides a fan module, which solves the problem that the conventional fan only has a heat dissipation function, but does not allow the user to know the relevant information of the fan operation efficiency, and the conventional illumination fan can only provide a simple light and shade. The change, which also fails to provide the user with information about the performance of the fan, and in use, the user's eyes are easily exposed by the light-emitting elements of the light-emitting fan, which seriously affects the user's comfort when operating the electronic device. .
本發明之風扇模組，包括一殼體、一風扇、一導光件、一發光元件以及一電路單元。殼體具有一基座以及罩覆基座之一外框，風扇可轉動的設置於基座上，且風扇具有一旋轉週期。導光件沿風扇的徑向設置於風扇上，並且相對基座具有一識別位置，導光件係配合旋轉週期位移至識別位置。發光元件設置於外框上，並且面向於導光件之一端，發光元件具有一脈衝週期，發光元件依據脈衝週期發射一光線至導光件，令光線於識別位置上形成一光束。電路單元設置於基座上，並且電性連接於風扇以及發光元件，用以控制風扇的旋轉週期以及發光元件的脈衝週期。The fan module of the present invention comprises a casing, a fan, a light guiding member, a light emitting component and a circuit unit. The housing has a base and an outer frame covering the base. The fan is rotatably disposed on the base, and the fan has a rotation period. The light guiding member is disposed on the fan in a radial direction of the fan, and has an identification position with respect to the base, and the light guiding member is displaced to the identification position in accordance with the rotation period. The illuminating element is disposed on the outer frame and faces one end of the light guiding member. The illuminating element has a pulse period, and the illuminating element emits a light to the light guiding member according to the pulse period, so that the light forms a light beam at the identifying position. The circuit unit is disposed on the base and electrically connected to the fan and the light emitting element for controlling the rotation period of the fan and the pulse period of the light emitting element.
本發明之功效在於，透過在風扇上設置發光元件以及導光件，以及發光元件的脈衝週期配合風扇的旋轉週期的運作模式，讓導光件依據不同的旋轉週期在相對應的識別位置上，接收發光元件所發射的光線，使光線在導光件上形成具有指向性的光束。因此，讓使用者可依據光線在風扇上形成光束的位置，直接的判斷出當時風扇的旋轉速度。同時，透過導光件沿輪轂徑向導引光線的設置方式，可避免發光元件所發射的光線照射到使用者的眼部而產生刺激或干擾，因此可提升使用者操作電子裝置時的舒適度。The effect of the invention is that, by providing the light-emitting element and the light-guiding member on the fan, and the pulse period of the light-emitting element is matched with the operation mode of the rotation period of the fan, the light guide member is at the corresponding recognition position according to different rotation periods. The light emitted by the light-emitting element is received to form a light beam having directivity on the light guide. Therefore, the user can directly determine the rotational speed of the fan at that time according to the position where the light forms a light beam on the fan. At the same time, the way of guiding the light along the radial direction of the light guide through the light guide member can prevent the light emitted by the light-emitting element from being irradiated to the eye of the user and causing irritation or interference, thereby improving the comfort of the user when operating the electronic device. .
有關本發明的特徵、實作與功效，茲配合圖式作最佳實施例詳細說明如下。The features, implementations, and utilities of the present invention are described in detail below with reference to the drawings.

請參照第1圖至第3圖，為本發明第一實施例所揭露的風扇模組10，其包括一基座110、一風扇120、一固定件130、一導光件140、一外框150、一發光元件160以及一電路單元170。風扇120設置於基座110上，風扇120包括一輪轂121以及複數個扇葉122，複數個扇葉122沿輪轂121的圓周環繞設置於輪轂121表面，輪轂121透過內部所設置的轉軸樞設於基座110上，而可相對基座110旋轉，並且具有一旋轉週期。此為一般風扇120樞設於基座110的設置方式，亦非本發明所欲強調之特徵，在此不再贅述。Referring to FIG. 1 to FIG. 3 , a fan module 10 according to a first embodiment of the present invention includes a base 110 , a fan 120 , a fixing member 130 , a light guide 140 , and a frame . 150. A light emitting element 160 and a circuit unit 170. The fan 120 is disposed on the base 110. The fan 120 includes a hub 121 and a plurality of blades 122. The plurality of blades 122 are circumferentially disposed on the surface of the hub 121 along the circumference of the hub 121. The hub 121 is pivoted through the rotating shaft disposed therein. The base 110 is rotatable relative to the base 110 and has a rotation period. This is a manner in which the general fan 120 is pivotally disposed on the base 110, and is not a feature of the present invention, and details are not described herein again.
固定件130以及導光件140分別設置在風扇120的輪轂121上，並且位於輪轂121相對基座110的另一側面上。固定件130可以是但並不侷限於圓周半徑等於或小於輪轂121圓周半徑的片材或板材。固定件130上形成有一穿孔131以及一溝槽132，穿孔131形成於固定件130的中心，溝槽141連通於穿孔131，並且沿著固定件130的徑向延伸，並且在固定件130的外周緣形成一放射狀開口133。因此，當固定件130設置於輪轂121上，固定件130的穿孔131對應於輪轂121的軸心，溝槽132的延伸方向平行於輪轂121的徑向，並且使放射狀開口133對應於輪轂121的外周緣。The fixing member 130 and the light guiding member 140 are respectively disposed on the hub 121 of the fan 120 and on the other side of the hub 121 opposite to the base 110. The fixture 130 may be, but is not limited to, a sheet or sheet having a circumferential radius equal to or smaller than the circumferential radius of the hub 121. A fixing hole 130 is formed with a through hole 131 formed at a center of the fixing member 130, a groove 141 communicating with the through hole 131, and extending along a radial direction of the fixing member 130, and at the outer periphery of the fixing member 130. The edge forms a radial opening 133. Therefore, when the fixing member 130 is disposed on the hub 121, the through hole 131 of the fixing member 130 corresponds to the axial center of the hub 121, the extending direction of the groove 132 is parallel to the radial direction of the hub 121, and the radial opening 133 corresponds to the hub 121. The outer circumference.
導光件140可以是但並不侷限於光纖，導光件140具有相對的一第一端141以及一第二端142，導光件140的第一端141對應於輪轂151的軸心，導光件140的第二端142朝輪轂121的徑向延伸，並且靠近或突出於輪轂121的外周緣。導光件140可經由固定件130的放射狀開口133穿設於固定件130的溝槽132內，使導光件140的第一端141伸入固定件130的穿孔131，以及使導光件140的第二端142容置於固定件130的放射狀開口133中。此外，導光件140的第一端141設置有一斜面143，斜面143是沿著輪轂121的圓周往軸心的方向，從導光件140的第一端141遠離基座110之一側朝向靠近基座110之一側傾斜設置，使導光件140的第一端141在固定件130的穿孔131內形成一斜切口。The light guide 140 can be, but is not limited to, an optical fiber. The light guide 140 has a first end 141 and a second end 142. The first end 141 of the light guide 140 corresponds to the axis of the hub 151. The second end 142 of the light member 140 extends in the radial direction of the hub 121 and is adjacent to or protrudes from the outer circumference of the hub 121. The light guide 140 can be inserted into the groove 132 of the fixing member 130 via the radial opening 133 of the fixing member 130, so that the first end 141 of the light guiding member 140 protrudes into the through hole 131 of the fixing member 130, and the light guiding member The second end 142 of the 140 is received in the radial opening 133 of the fixture 130. In addition, the first end 141 of the light guiding member 140 is provided with a sloped surface 143 which is in the direction of the axis along the circumference of the hub 121, and is away from the side of the first end 141 of the light guiding member 140 away from the side of the base 110. One side of the base 110 is obliquely disposed such that the first end 141 of the light guide 140 forms a oblique cut in the through hole 131 of the fixing member 130.
此外，由於導光件140是固定在風扇120的輪轂121上，並且沿著輪轂121的徑向設置，使導光件140具有指向性，並且相對於基座110具有一識別位置。因此，當風扇120透過輪殼121相對基座110轉動時，會一併帶動導光件140相對基座110旋轉，使導光件140相對基座110產生位移而改變其相對於基座110的方位，促使導光件140相對於基座110具有不同的識別位置。同時，導光件140是配合風扇120的旋轉週期而在不同的識別位置之間位移。Further, since the light guide 140 is fixed to the hub 121 of the fan 120 and disposed along the radial direction of the hub 121, the light guide 140 has directivity and has an identification position with respect to the base 110. Therefore, when the fan 120 is rotated relative to the base 110 through the wheel housing 121, the light guide 140 is rotated relative to the base 110 to change the light guide 140 relative to the base 110 to change its relative to the base 110. The orientation causes the light guide 140 to have a different identification position relative to the base 110. At the same time, the light guide 140 is displaced between different recognition positions in accordance with the rotation period of the fan 120.
如第1圖至第3圖所示，風扇模組10的外框150罩覆於基座110上，並且在外框150與基座110的設置方式上，可以是將外框150直接的固定在基座110上；或者是，當風扇模組10設置在電子產品內部承載有電子元件30的基板20時，可以將風扇模組10的基座110設置於電子元件30上，以及將外框150蓋合並固定於基板20上，使外框150罩覆在基座110上。在本發明的實施例中，是以外框150固定於承載有電子元件30的基板20上，並且罩覆於基座110上做為舉例說明，但在實際應用上，可依據外框150的尺寸大小來選擇外框150與基座110的組裝方式，而並非以所述的設置方式為限。As shown in FIG. 1 to FIG. 3 , the outer frame 150 of the fan module 10 is covered on the base 110 , and in the manner in which the outer frame 150 and the base 110 are disposed, the outer frame 150 can be directly fixed on the outer frame 150 . On the base 110; or when the fan module 10 is disposed on the substrate 20 carrying the electronic component 30 inside the electronic product, the base 110 of the fan module 10 can be disposed on the electronic component 30, and the outer frame 150 can be The cover is affixed and fixed to the substrate 20, and the outer frame 150 is covered on the base 110. In the embodiment of the present invention, the outer frame 150 is fixed on the substrate 20 carrying the electronic component 30, and is covered on the base 110 as an example, but in practical applications, according to the size of the outer frame 150. The size of the outer frame 150 and the base 110 are selected in an assembly manner, and are not limited to the arrangement described.
其中，在外框150相對風扇120的一側面上形成有複數個開口151，複數個開口151分別對應於部分風扇120以及導光件，使風扇120以及導光件140露出於開口151。A plurality of openings 151 are formed on one side of the outer frame 150 with respect to the fan 120. The plurality of openings 151 respectively correspond to the partial fan 120 and the light guide, so that the fan 120 and the light guide 140 are exposed to the opening 151.
發光元件160設置於外框150相對風扇120之一側面上，並且對應於導光件141的第一端141。發光元件160可以是但並不侷限於發光二極體(light-emitting diode，LED)，發光元件160電性連接於電路單元170，並且以一脈衝週期發射一光線至導光件140，以藉由導光件140導引光線沿輪轂121的徑向傳遞至外界環境。The light emitting element 160 is disposed on one side of the outer frame 150 opposite to the fan 120 and corresponds to the first end 141 of the light guide 141. The light-emitting element 160 can be, but is not limited to, a light-emitting diode (LED). The light-emitting element 160 is electrically connected to the circuit unit 170, and emits a light to the light guide 140 in a pulse period. Light is guided by the light guide 140 to be transmitted to the external environment in the radial direction of the hub 121.
電路單元170設置在基座110上，並且電性連接於風扇以及發光元件。電路單元170可以是但並不侷限於配置有控制電路以及一微處理晶片171的電路板，並且在電路單元170上可選擇性的電性設置一轉速感測器172以及一溫度感測器173。The circuit unit 170 is disposed on the base 110 and electrically connected to the fan and the light emitting element. The circuit unit 170 can be, but is not limited to, a circuit board configured with a control circuit and a micro processing chip 171, and a speed sensor 172 and a temperature sensor 173 are selectively electrically disposed on the circuit unit 170. .
電路單元170可以是但並不侷限於電性設置有控制電路以及一微處理晶片141的電路板。電路單元170設置在基座110與風扇120之間上，並且電性連接於風扇120以及發光元件160。電路單元170透過微處理晶片171控制風扇120的旋轉週期以及發光元件160的脈衝週期，使導光件140配合不同的旋轉週期位移至不同的識別位置，以及使發光元件160的脈衝週期配合風扇120的旋轉週期，讓發光元件160依據脈衝週期所發射的光線，可以配合風扇120的旋轉週期，而投射至導光件140，使光線受到導光件140的導引與傳遞而形成光束。因此，當風扇120以不同的旋轉週期相對基座110轉動時，可以讓導光件140依據當時風扇120的旋轉週期，而在相對應的識別位置上發光。Circuit unit 170 can be, but is not limited to, a circuit board that is electrically provided with control circuitry and a microprocessor chip 141. The circuit unit 170 is disposed between the susceptor 110 and the fan 120 and electrically connected to the fan 120 and the illuminating element 160. The circuit unit 170 controls the rotation period of the fan 120 and the pulse period of the light-emitting element 160 through the micro-process wafer 171, and the light guide 140 is displaced to different recognition positions with different rotation periods, and the pulse period of the light-emitting element 160 is matched with the fan 120. The rotation period of the light-emitting element 160 is caused to be incident on the light guide member 140 in accordance with the rotation period of the fan 120, so that the light is guided and transmitted by the light guide member 140 to form a light beam. Therefore, when the fan 120 rotates relative to the base 110 at different rotation periods, the light guide 140 can be illuminated at a corresponding recognition position according to the rotation period of the fan 120 at that time.
請參照第2圖至第4圖，舉例而言，當電路單元170控制風扇120以一第一旋轉週期相對基座110轉動，使風扇120以順時鐘方向轉動時，電路單元170控制發光元件160以固定的脈衝週期配合第一旋轉週期發射一光線，例如控制脈衝週期的週期數等於第一旋轉週期的週期數(如第4圖所示)，使光線在導光件140相對基座110位移至一第一識別位置時照射至導光件140，並且經由第一端141的斜切口進入導光件140內，再藉由導光件140的傳遞而從導光件140的第二端142射出，使光線形成沿輪轂121的徑向發射的指引光束，並且使導光件140在第一識別位置上發光。因此，當使用者從風扇120朝向基座110的方向觀看風扇模組10時，可以在風扇120上的特定位置注意到由導光件140所形成的光束。在本實施例中，當脈衝週期的週期數等於第一旋轉週期的週期數時，第一識別位置為對應於風扇的12點鐘方向的位置。Referring to FIGS. 2 to 4 , for example, when the circuit unit 170 controls the fan 120 to rotate relative to the susceptor 110 in a first rotation period to rotate the fan 120 in the clockwise direction, the circuit unit 170 controls the light-emitting element 160. Transmitting a ray with a fixed pulse period in conjunction with the first rotation period, for example, controlling the number of periods of the pulse period to be equal to the number of periods of the first rotation period (as shown in FIG. 4), causing the light to be displaced at the light guide 140 relative to the susceptor 110 Illuminating to the light guide 140 when the first recognition position is reached, and entering the light guide 140 via the oblique cut of the first end 141, and then passing from the second end 142 of the light guide 140 by the transmission of the light guide 140 The light is emitted such that the light forms a directing beam that is emitted in the radial direction of the hub 121, and causes the light guide 140 to emit light at the first identification position. Therefore, when the user views the fan module 10 from the fan 120 toward the susceptor 110, the light beam formed by the light guide 140 can be noticed at a specific position on the fan 120. In the present embodiment, when the number of cycles of the pulse period is equal to the number of cycles of the first rotation period, the first identification position is a position corresponding to the 12 o'clock direction of the fan.
請參照第2圖、第5圖和第6圖，此外，在發光元件160的脈衝週期為定值的狀態下，當電路單元170以小於第一旋轉週期的一第二旋轉週期控制風扇120轉動，以加快風扇120的轉速時，由於導光件140是固定在風扇120的輪轂121上，並且隨著風扇120旋轉，因此當發光元件130依據脈衝週期發射光線時，導光件140將配合第二旋轉週期在相對基座110的一第二識別位置接收光線，進而在第二識別位置上發光。Referring to FIG. 2, FIG. 5, and FIG. 6, in addition, in a state where the pulse period of the light-emitting element 160 is constant, the circuit unit 170 controls the rotation of the fan 120 at a second rotation period smaller than the first rotation period. In order to speed up the rotation of the fan 120, since the light guide 140 is fixed to the hub 121 of the fan 120, and as the fan 120 rotates, when the light-emitting element 130 emits light according to the pulse period, the light guide 140 will cooperate with the first The second rotation period receives light at a second identification position relative to the susceptor 110, thereby illuminating at the second identification position.
例如，當電路單元170以第二旋轉週期控制風扇120轉動，使風扇120轉速從1200rpm提升至2000rpm時，第二旋轉週期的週期數，將會從相等於脈衝週期的週期數改變為大於脈衝週期的週期數，使第二旋轉週期領先脈衝週期0.5個週期，讓第二識別位置對應於風扇120的6點鐘方向(如第5圖和第6圖所示)。For example, when the circuit unit 170 controls the rotation of the fan 120 in the second rotation cycle to increase the rotation speed of the fan 120 from 1200 rpm to 2000 rpm, the number of cycles of the second rotation cycle will change from the number of cycles equal to the pulse period to be larger than the pulse period. The number of cycles is such that the second rotation period leads the pulse period by 0.5 cycles, and the second identification position corresponds to the 6 o'clock direction of the fan 120 (as shown in FIGS. 5 and 6).
因此，在風扇模組10的使用上，讓使用者可直接依據導光件140在風扇120上發光時的相對位置，即時得知風扇120的運轉速度。並且，在本實施例中，另可選擇性的在電路單元170上電性設置一溫度感測器172，用以偵測風扇120內部的工作溫度，使電路單元170可依據此工作溫度控制發光元件160所發射光線的色彩。例如，當工作溫度約為30℃時，電路單元170控制發光元件160發射綠色光束；當工作溫度約為60℃時，電路單元170控制發光元件160發射紫色光束；以及當工作溫度約為90℃時，電路單元170控制發光元件160發射紅色光束等。讓使用者除了風扇120轉速外，可同時得知風扇120運作時的溫度狀態。Therefore, in the use of the fan module 10, the user can immediately know the running speed of the fan 120 according to the relative position of the light guide 140 when the light is emitted on the fan 120. In addition, in the embodiment, a temperature sensor 172 is selectively disposed on the circuit unit 170 for detecting the operating temperature inside the fan 120, so that the circuit unit 170 can control the illumination according to the operating temperature. The color of the light emitted by element 160. For example, when the operating temperature is about 30 ° C, the circuit unit 170 controls the light-emitting element 160 to emit a green light beam; when the operating temperature is about 60 ° C, the circuit unit 170 controls the light-emitting element 160 to emit a purple light beam; and when the operating temperature is about 90 ° C At this time, the circuit unit 170 controls the light emitting element 160 to emit a red light beam or the like. In addition to the rotation speed of the fan 120, the user can simultaneously know the temperature state of the fan 120 during operation.
此外，雖然在本發明第一實施例所揭露的風扇模組10中，由於發光元件160的脈衝週期是透過電路單元170控制為定值，因此在不同的風扇120轉速下，發光元件160所發射的光線始終在單一識別位置於導光件140上形成光束。但是，在本發明的其他實施例中，電路單元170可選擇性的電性設置一轉速感測器173，用以偵測風扇120轉速，讓電路單元170可依據風扇120轉速控制發光元件160的脈衝週期，使發光元件160配合風扇120的旋轉週期，以不同的脈衝週期發射光線。例如，當風扇120以第一旋轉週期轉動時，發光元件160仍然只在導光件140位於第一識別位置時發射光線。但是當風扇120以第二旋轉週期轉動時，發光元件160可同時於第一識別位置以及第二識別位置發射光線，讓導光件140同時在風扇120上的二個不同位置處發光，例如同時在風扇120的12點鐘方向以及1點鐘方向形成指向光束。In addition, in the fan module 10 disclosed in the first embodiment of the present invention, since the pulse period of the light-emitting element 160 is controlled by the circuit unit 170 to be constant, the light-emitting element 160 is emitted at different speeds of the fan 120. The light rays always form a light beam on the light guide 140 at a single recognition position. However, in other embodiments of the present invention, the circuit unit 170 can selectively electrically set a rotational speed sensor 173 for detecting the rotational speed of the fan 120, so that the circuit unit 170 can control the light emitting element 160 according to the rotational speed of the fan 120. The pulse period causes the light-emitting element 160 to cooperate with the rotation period of the fan 120 to emit light at different pulse periods. For example, when the fan 120 is rotated in the first rotation cycle, the light-emitting element 160 still emits light only when the light guide 140 is in the first recognition position. However, when the fan 120 rotates in the second rotation period, the light-emitting element 160 can simultaneously emit light at the first recognition position and the second recognition position, so that the light guide 140 simultaneously emits light at two different positions on the fan 120, for example, at the same time. A directed light beam is formed at the 12 o'clock direction and the 1 o'clock direction of the fan 120.
再者，電路單元170亦可控制發光元件160在導引件140從第一識別位置位移至第二識別位置的時間區間內持續的發射光線，使光線在風扇120上形成一光幕，例如在風扇120的12點鐘方向與3點鐘方向之間形成扇形光幕，可進一步提升使用者觀察風扇120轉速及溫度時的識別性與便利性。Moreover, the circuit unit 170 can also control the light emitting element 160 to continuously emit light during a time interval in which the guiding member 140 is displaced from the first identifying position to the second identifying position, so that the light forms a light curtain on the fan 120, for example, A fan-shaped light curtain is formed between the 12 o'clock direction and the 3 o'clock direction of the fan 120, which further enhances the visibility and convenience when the user observes the rotation speed and temperature of the fan 120.
此外，在本發明之風扇模組中，當電路單元170驅動發光元件160發射光線，此光線經由導光件140之第一端141所形成的斜切口進入導光件140，並且透過導光件140的導引，而從導光件140的第二端142射出，使光線沿著輪殼121的徑向照射，因此可避免光線直接的照射於使用者的眼部而產生不適，同時可避免使用者因直視於光源而產生暫時性失明的情形發生。In addition, in the fan module of the present invention, when the circuit unit 170 drives the light-emitting element 160 to emit light, the light enters the light guide 140 through the oblique slit formed by the first end 141 of the light guide 140, and passes through the light guide. The guiding of the 140 is emitted from the second end 142 of the light guiding member 140, so that the light is irradiated along the radial direction of the wheel housing 121, thereby preventing the light from directly irradiating the user's eyes and causing discomfort, and avoiding The user experiences temporary blindness due to direct view of the light source.
請參閱第7圖和第8圖所示，為本發明第二實施例所揭露的風扇模組，其與本發明第一實施例之間的差異在於，第二實施例所揭露的風扇模組10中，在風扇120的輪轂121上更設置有一遮光件180，以及在風扇120的複數個扇葉122中，與導光件140相對應的扇葉122上設置一反光件190。遮光件180設置於輪轂1121上由固定件130與導光件140所形成的共平面上，並且在遮光件180上形成有一通孔181，通孔181對應輪轂121的軸心，使導光件140的第一端141露出於通孔181，以便於接收發光元件160所發射的光線。反光件190可以是但並不侷限於塗覆於扇葉122上的反光塗層或反光貼紙。Referring to FIG. 7 and FIG. 8 , the fan module disclosed in the second embodiment of the present invention is different from the first embodiment of the present invention in the fan module disclosed in the second embodiment. In FIG. 10, a light blocking member 180 is further disposed on the hub 121 of the fan 120, and in the plurality of blades 122 of the fan 120, a reflector 190 is disposed on the blade 122 corresponding to the light guiding member 140. The light blocking member 180 is disposed on the common plane formed by the fixing member 130 and the light guiding member 140 on the hub 1121, and a through hole 181 is formed in the light blocking member 180. The through hole 181 corresponds to the axial center of the hub 121, so that the light guiding member The first end 141 of the 140 is exposed to the through hole 181 to receive the light emitted by the light emitting element 160. Reflector 190 can be, but is not limited to, a reflective coating or reflective sticker applied to blade 122.
其中，由於導光件140受到遮光件180的遮蔽，使光線從導光件140的第一端141進入導光件140後，可以被集中從導光件140的第二端142射出，進而加強光線在輪轂121的徑向上所形成光束的強度。此外，當光線從輪轂121的徑向射出時，會直接的照射於相對應扇葉122上所設置的反光件190，並且受到反光件190的反射，使扇葉122在風扇120上形成發光範圍較大的一亮光區域。由於導光件140是在識別位置上接收光線，並且將光線導引至反光件190，因此扇葉122上所形成的亮光區域可以做為識別位置的延伸，讓使用者更加方便的觀察到光線在風扇120上的相對位置，而有助於判斷風扇120當時的旋轉速度。The light guide member 140 is shielded by the light shielding member 180, so that the light enters the light guide member 140 from the first end 141 of the light guide member 140, and can be concentratedly emitted from the second end 142 of the light guide member 140, thereby strengthening The intensity of the light beam formed by the light rays in the radial direction of the hub 121. In addition, when the light is emitted from the radial direction of the hub 121, it directly illuminates the reflector 190 disposed on the corresponding blade 122, and is reflected by the reflector 190, so that the blade 122 forms a range of illumination on the fan 120. A larger area of light. Since the light guide 140 receives light at the recognition position and guides the light to the reflector 190, the bright region formed on the blade 122 can be used as an extension of the recognition position, allowing the user to observe the light more conveniently. The relative position on the fan 120 helps to determine the rotational speed of the fan 120 at that time.
雖然在上述實施例中，風扇模組10是採用單一發光元件160對應單一導光件140的設置方式，但是在本發明的其他實施例中，也可以是採用複數個發光元件160對應單一導光件140的設置方式，如第9圖所示，複數個發光元件160設置在外框150相對風扇120的一側面上，並且對應於風扇120的輪轂121圓周而環繞設置在外框150上，讓導光件140的第二端142在導光件140配合風扇120的旋轉週期轉動時，可以在不同的識別位置上對應於其中一發光元件160。因此，當發光元件160配合風扇120的旋轉週期發射光線，以及導光件140配合風扇120的旋轉週期而位移至相對應的識別位置時，發光元件160所發射的光線可以在識別位置上照亮導光件140，讓使用者可以依據導光件140在風扇120上的相對位置在判斷風扇120轉速。In the above embodiment, the fan module 10 is configured to use a single light-emitting element 160 corresponding to the single light guide 140. However, in other embodiments of the present invention, a plurality of light-emitting elements 160 may be used for a single light guide. The arrangement of the member 140 is as shown in FIG. 9. A plurality of light-emitting elements 160 are disposed on one side of the outer frame 150 opposite to the fan 120, and are disposed around the circumference of the hub 121 of the fan 120 to be disposed on the outer frame 150 to allow light guiding. The second end 142 of the member 140 can correspond to one of the light-emitting elements 160 at different recognition positions when the light guide 140 rotates in conjunction with the rotation period of the fan 120. Therefore, when the light-emitting element 160 emits light in accordance with the rotation period of the fan 120, and the light guide 140 is displaced to the corresponding recognition position in accordance with the rotation period of the fan 120, the light emitted by the light-emitting element 160 can be illuminated at the recognition position. The light guide 140 allows the user to determine the rotational speed of the fan 120 according to the relative position of the light guide 140 on the fan 120.
上述本發明之風扇模組，透過導光件隨著風扇轉動而變換其相對基座的識別位置，以及發光元件的脈衝週期配合風扇的旋轉週期的運作模式，讓導光件在接收發光元件所產生的光線後，可以在與風扇轉速相對應的識別位置上形成具有指向性的光束，讓使用者可直接依據光束的指引方向判斷當時的風扇轉速，並且藉由光線色彩的轉換，讓使用者可同時判斷風扇運轉時的工作溫度。此外，透過光線沿輪轂的徑向照射的設置方式，降低使用者的眼部受到光線照射，或者是直視於光源的機率，進而避免使用者的眼部產生不適或者是暫時性失明的情形發生。In the fan module of the present invention, the light guide member changes its recognition position relative to the base as the fan rotates, and the pulse period of the light-emitting element cooperates with the operation mode of the rotation period of the fan, so that the light guide member receives the light-emitting element. After the generated light, a directional light beam can be formed at the identification position corresponding to the fan speed, so that the user can directly judge the current fan speed according to the direction of the beam, and the user can convert the color of the light to allow the user to convert the color of the light. The operating temperature at which the fan is running can be judged at the same time. In addition, the arrangement of the light in the radial direction of the hub reduces the probability of the user's eyes being exposed to light or directly looking at the light source, thereby preventing the user's eye from being uncomfortable or temporarily blind.
