Description of the Invention: [Technical Field] The present invention relates to a portable power supply device, and more particularly to a portable solar power supply device. [Prior Art] Nowadays, portable electronic devices, such as mobile phones, MP3s, etc., have become daily necessities for people. These portable electronic devices typically require their own battery to provide power. Because of the limited amount of power stored in the battery and the need to consume more power while achieving rich functionality, it is often necessary to use a spare battery to overcome the above deficiencies. However, when the power of the backup battery is also exhausted, the portable electronic device can no longer be used. In view of this, it is necessary to provide a portable power supply device capable of providing continuous power. φ [Summary of the Invention] A portable power supply device capable of providing continuous electric power will be described below by way of example. A portable power supply device comprising a hollow light transmissive housing, a light guiding element, a collecting lens, a light energy converting element and an electrical energy output element. The housing has a first index of refraction and sunlight enters the housing via at least a portion of the outer surface of the housing. The light guiding element is disposed in the housing and is attached to the housing 4 201029201. The light guiding element has a second refractive index greater than the first refractive index. The concentrating lens is disposed in the housing and adjacent to the light guiding element. The concentrating lens is for collecting light transmitted through the light guiding element and incident on the collecting lens. The light energy conversion element is disposed in the housing for receiving light concentrated by the collecting lens and converting the light energy into electrical energy. The power output component is electrically connected to the light energy conversion component, and the electrical energy generated by the light energy conversion component is output via the power output component. Compared with the prior art, the housing of the portable power supply device is internally provided with a light guiding element, and the light guiding element has a second refractive index greater than the first refractive index of the housing, so that sunlight entering the interior of the housing is The interior of the light guiding element is susceptible to total reflection. The sunlight transmitted inside the casing is concentrated by the collecting lens and incident on the light converting element. The light energy conversion element converts the received sunlight into electrical energy, and outputs the portable power supply device via the power output element to provide continuous electrical energy to other electronic devices. Further, due to the convergence of the collecting lens, the light incident on the light converting element is concentrated, so that the light converting element has a high photoelectric conversion efficiency. [Embodiment] Hereinafter, embodiments of the present invention will be further described in detail with reference to the accompanying drawings. Referring to FIG. 1 and FIG. 2, a first embodiment of the present invention provides a portable power supply device 10, which includes a light-transmitting housing 11, a light-guiding 7L member 12, and a collecting lens 13. , a light energy conversion element, a component 14 and an electrical energy output component 15. The light transmissive housing 11 has a hollow plate-like structure including a top plate 112 and a bottom plate 114. The top surface 1120 of the top plate 112 is the first light-incident surface of the light-transmitting body 11 and the bottom surface 1140 of the bottom plate 114 is the second light-incident surface of the light-transmitting casing 11. Sunlight enters the light transmissive housing 11 via the top surface 1120 of the top plate 112 and the bottom surface 1140 of the bottom plate 114. The top plate 112 and the bottom plate 114 have a first index of refraction. The light guiding element 12 is disposed in the light transmissive housing U and located between the top plate 112 and the bottom plate 114. The light guiding element 12 includes a first reflecting sheet 122 and a second reflecting sheet 124 opposite to the first reflecting sheet 122. The first reflection sheet 122 and the second reflection sheet 124 are respectively attached to the top plate 112 and the bottom plate U4. The second reflecting sheet 122 having the second reflecting sheet 24 having the second refractive index larger than the first refractive index is disposed in the light transmitting casing π and adjacent to the light guiding element 12. The collecting lens 13 is for collecting light transmitted through the light guiding element and incident thereon. The light energy conversion element 14 is disposed in the light transmissive housing 且 adjacent to the light guiding element 12 and the condensing lens 13 is disposed on one side of the light energy conversion element 14 adjacent to the light guiding element 12. The light energy conversion unit $14 is for receiving the light concentrated by the collecting lens 13, and converting its 6 201029201 into electric energy. In the present embodiment, the light energy conversion element 14 is a solar panel. The power output element 15 is electrically connected to the light energy conversion element 14. The electric energy generated by the light energy conversion element 14 is rotated through the electric energy output element 15.
由於上述第一折射率小於上述第二折射率，所 乙太陽光可順利地經由頂板112之頂面1120及底板 114之底面1140進入導光元件12中。由於上述第二 折射率大於上述第一折射率，所以射入導光元件12 中之太陽光於第一反射片122與頂板112相貼合之 表面以及第二反射片124與底板114相貼合之表面 容易發生全反射，使得導光元件12中之太陽光能夠 有效地傳輸至聚光透鏡13。聚光透鏡13將射至其 上之太陽光會聚到光能轉換元件14上，光能轉換元 件14將接收到之光能轉換為電能並進行儲存。電能 輸出元件15可光能轉換元件14產生之電能輸出^ 對該便攜式供電裝置1G之外之其他電子I置提供 持續地電能。另，由於聚光透鏡13之會聚作用，射 ^光能轉換元件14上之光線較為集中，從而使得光 月&轉換元件14具有較高之光電轉換效率。 相參見圖3與圖4,本發明第二實施例提供— 電裝置20，其與第一實施例提供之便攜式 供電裝置U)基本相同，不同之處在於··便攜式供^ 7 201029201 裝置20進一步包括保護層28。 _ ㈣層28覆蓋殼體之外表面，以避免因碰 撞、潮濕、強光等不利因素使便攜式供電裝置加受 到損壞。保護層28所用材料可為透光材料，亦可為 不透光材料。當保護層28所用材料為透光材料例 如石夕膠、塑勝等’保護層28可覆蓋殼體21之整個 外表面，使便攜式供電裝置2〇所包括之其他元件全 ❹被保護層28包覆於其，。當保護層28所用材料為 不透光材料，保護層28可覆蓋殼體21之部分外表 面’使頂板212之頂面212〇與底板214之底面214〇 中之至少一者暴露於外。於本實施例中，頂板 之頂面2120暴露於外，以使太陽光經由頂板212之 頂面2120進入殼體21内部之導光元件22。 便攜式供電裝置20之工作原理與上述便攜式供 電裝置10之基本相同，於此不再贅述。 請參見圖5’本發明第三實施例提供一種便攜式 供電裝置30，其與第一實施例提供之便攜式供電裝 置1〇基本相同，不同之處在於：頂板312之頂面 3120為曲面，底板314之底面314〇上設置有微結 構3142，所以頂面3120與底面314〇具有相對於平 面較大之面積，這樣可增加進入便攜式供電裝置3〇 中之光量，提高光能轉換元件34之光電轉換效率。 可理解地，頂板312之頂面3120與底板314之 201029201 底面3140亦可同時為曲面或同時於其上設置微結 構；頂板312之頂面3120與底板314之底面3140 中一者亦可為平面。 請參見圖6與圖7,本發明第四實施例提供之一 種便攜式供電裝置40,其包括一個殼體41，一個導 光元件42，一個聚光透鏡43，一個光能轉換元件 44及一個電能輸出元件45。 ❹ 殼體41具有中空柱狀結構，其具有第一折射率。 導光元件42設置於殼體41内，且與該殼體41 之内侧壁相貼合。導光元件42具有大於該第一折射 率之第二折射率。 聚光透鏡43設置於殼體41内且與導光元件42 相鄰。聚光透鏡43用於會聚經由導光元件42傳輸 之並射至其上之光線。 _ 光能轉換元件44設置於殼體41中並與導光元 件42相鄰，且聚光透鏡43設置於光能轉換元件44 之與導光元件42相鄰之一側。光能轉換元件44用 於接收經由聚光透鏡43會聚之光線，並將其轉換為 電能。於本實施例中，光能轉換元件44為太陽能電 池板。 電能輸出元件45與光能轉換元件44電性連 接。光能轉換元件44產生之電能經由電能輸出元件 9 201029201 45輸出。 便攜式供電裝置40之工作原理與上述便攜式供 電裝置10之基本相同，於此不再贅述。 綜上所述，本發明確已符合發明專利之要件， 遂依法提出專利申請。惟，以上所述者僅為本發明 之較佳實施方式，自不能以此限制本案之申請專利Since the first refractive index is smaller than the second refractive index, the sunlight can smoothly enter the light guiding element 12 via the top surface 1120 of the top plate 112 and the bottom surface 1140 of the bottom plate 114. Since the second refractive index is greater than the first refractive index, the sunlight incident on the light guiding element 12 is adhered to the surface of the first reflective sheet 122 and the top plate 112, and the second reflective sheet 124 is bonded to the bottom plate 114. The surface is susceptible to total reflection so that sunlight in the light guiding element 12 can be efficiently transmitted to the collecting lens 13.

When the material used for the protective layer 28 is a light transmissive material such as a stone, plastic, etc., the protective layer 28 can cover the entire outer surface of the casing 21, so that the other components included in the portable power supply device 2 are covered by the protective layer 28 Covered with it. When the material used for the protective layer 28 is an opaque material, the protective layer 28 may cover a portion of the outer surface of the housing 21 to expose at least one of the top surface 212 of the top plate 212 and the bottom surface 214 of the bottom plate 214 to the outside. In the present embodiment, the top surface 2120 of the top plate is exposed to the outside so that sunlight enters the light guiding element 22 inside the casing 21 via the top surface 2120 of the top plate 212.
