Description
本創作係涉及涉及直流風扇，尤其涉及一種發光均勻的直流風扇。The present invention relates to a DC fan, and more particularly to a DC fan with uniform illumination.
現有的散熱風扇一般只是使用傳統的LED發光，直接由LED發出光線，光照不均勻，而且基本沒有集光效果，會存在LED發光時光強弱不均勻的現象。The existing cooling fan generally uses only conventional LED illumination, directly emits light from the LED, the illumination is uneven, and there is basically no light collecting effect, and there is a phenomenon that the light intensity is uneven during the LED illumination.
本創作針對以上的問題提出了一種讓直流風扇中的LED發光的光感更加均勻更集中，光能效更大的導光散熱風扇。In response to the above problems, the present invention proposes a light guiding and cooling fan that makes the light of the LED in the DC fan more uniform and concentrated, and has more light energy efficiency.
本創作所提供之一種導光散熱風扇，包括風扇本體、驅動風扇的馬達、安裝馬達的支架和軸承；其特徵在於：在散熱風扇內設有導光部分，所述導光部分，包括依次層疊設置的反光板、導光板和擴散板。A light guiding heat dissipating fan provided by the present invention comprises a fan body, a motor for driving the fan, a bracket for mounting the motor, and a bearing; wherein: a light guiding portion is disposed in the heat dissipating fan, and the light guiding portion comprises a layered portion in sequence Reflector, light guide and diffuser are provided.
所述導光部分，可裝設於風扇框體或扇葉上。The light guiding portion can be mounted on the fan frame or the fan blade.
所述導光板可為可透光材質，最佳選擇為PC(Polycarbonate聚碳酸酯)或壓克力。The light guide plate may be a light transmissive material, and the best choice is PC (Polycarbonate polycarbonate) or acrylic.
所述導光板表面有網點，此網點可為網印或射出。The surface of the light guide plate has a dot, which may be screen printed or shot.
藉由上述構件之組成，可有效的實現散熱風扇的集光功能，改變導光散熱風扇LED發光光強不均勻的現象。By the composition of the above components, the light collecting function of the cooling fan can be effectively realized, and the phenomenon that the LED light intensity of the light guiding cooling fan is uneven is changed.
為了使本創作的目的、技術方案及優點更加清楚明白，以下結合附圖及實施例，對本創作進行進一步詳細說明。In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
如圖1所示係本創作一較佳之實施例，一般現在所用的散熱風扇一般只是使用傳統的LED發光，直接由LED發出光線，光照不均 勻，而本創作提出了一種導光散熱風扇，實現了讓發光LED在散熱風扇上發出亮度光線更加均勻而集中，所述導光散熱風扇包括風扇本體1、驅動風扇本體1的馬達2、安裝馬達2的支架3和軸承4，其特徵在於，在散熱風扇內設有導光部分，所述導光部分，包括依次層疊設置的反光板5、導光板6和擴散板7。利用導光技術實現為LED集光，實用反光板5將LED光反射，再利用導光板6將光匯出再到擴散板7上將光均勻顯示出來。As shown in FIG. 1 , a preferred embodiment of the present invention generally uses a conventional LED to emit light directly from the LED, and the illumination is uneven. Uniform, and the present invention proposes a light guiding cooling fan, which realizes that the luminous LED emits brightness light more uniformly and concentrated on the cooling fan, and the light guiding cooling fan comprises a fan body 1, a motor for driving the fan body 1, and an installation The bracket 3 and the bearing 4 of the motor 2 are characterized in that a light guiding portion is provided in the heat radiating fan, and the light guiding portion includes a reflecting plate 5, a light guiding plate 6, and a diffusing plate 7 which are laminated in this order. The LED light is collected by the light guiding technology, and the utility light reflecting plate 5 reflects the LED light, and then the light is taken out by the light guiding plate 6 and then distributed to the diffusing plate 7 to uniformly display the light.
所述導光部分，可裝設於風扇框體或扇葉上。The light guiding portion can be mounted on the fan frame or the fan blade.
所述導光板6可為可透光材質，最佳選擇為PC(Polycarbonate聚碳酸酯)或壓克力。The light guide plate 6 may be a light transmissive material, and the best choice is PC (Polycarbonate polycarbonate) or acrylic.
所述導光板表面有網點，此網點可為網印或射出。The surface of the light guide plate has a dot, which may be screen printed or shot.
藉由上述構件之組成，可有效的實現散熱風扇的集光功能，改變導光散熱風扇LED發光光強不均勻的現象。By the composition of the above components, the light collecting function of the cooling fan can be effectively realized, and the phenomenon that the LED light intensity of the light guiding cooling fan is uneven is changed.
惟，以上所述者，僅係本創作之一較佳可行實施例而已，故舉凡應用本創作說明書及申請專利範圍所為之等效結構變化，理應包含在本創作之專利範圍內。However, the above-mentioned ones are only one of the preferred embodiments of the present invention, and the equivalent structural changes in the application of the present specification and the scope of the patent application are intended to be included in the scope of the present patent.
