Description
本發明是有關於一種照明裝置，尤指一種可提高照明區域之照度、使照明區域之光強度分佈均勻以及可改變照明區域之樣態之照明裝置。 The invention relates to a lighting device, in particular to a lighting device which can improve the illumination of an illumination area, make the light intensity distribution of the illumination area uniform, and change the illumination area.
自古以來，農業是一種人類透過改造自然環境來進行生產之活動，人類將技術應用到自然環境中，藉以獲取經濟效益。但隨著人類之人口不斷地增加，以及地球之土地被過度地開發，特別是近年來全球之氣候變遷劇烈，風災、水災等等眾多天災接踵而至，皆對於農業產生極大之影響，甚至引發了地球糧食之供貨危機。 Since ancient times, agriculture has been an activity of human beings through the transformation of the natural environment. Humans have applied technology to the natural environment in order to obtain economic benefits. However, as the human population continues to increase and the land of the earth is overexploited, especially in recent years, the global climate has changed dramatically, and many natural disasters such as windstorms and floods have followed, which have had a great impact on agriculture and even triggered The supply crisis of the earth's food.
也因此，農業現代化之改革逐漸地被重視。植物工廠即為提供農作物一無污染、不受天災影響，且可提高農作物產量與品質之植物生產系統。而植物工廠傳統上多半採用螢光燈、鹵素燈或高壓鈉燈作為照明光源。但此種照明光源有使用壽命短以及高耗電量之缺點。近來隨著發光二極體之蓬勃發展，發光二極體逐漸取代螢光燈、鹵素燈或高壓鈉燈而作為植物工廠之新興照明光源。 Therefore, the reform of agricultural modernization has gradually been taken seriously. The plant factory is a plant production system that provides crops without pollution, is not affected by natural disasters, and can increase crop yield and quality. Most of the plant factories use fluorescent lamps, halogen lamps or high-pressure sodium lamps as illumination sources. However, such an illumination source has the disadvantages of short service life and high power consumption. Recently, with the rapid development of light-emitting diodes, light-emitting diodes have gradually replaced fluorescent lamps, halogen lamps or high-pressure sodium lamps as an emerging illumination source for plant factories.
然而，因發光二極體之發光角度大，所以有部分發光角度之 光線無法被有效照射至被照明區域上，降低了被照明區域之照度，亦造成光浪費。此外，被照明區域之光強度容易分佈不均。上述皆為仍待解決之技術課題。 However, since the light-emitting diode has a large light-emitting angle, there is a partial light-emitting angle. Light can not be effectively illuminated onto the illuminated area, reducing the illumination of the illuminated area and also wasting light. In addition, the light intensity of the illuminated area is easily distributed unevenly. All of the above are technical issues still to be resolved.
有鑑於習知技術之各項問題，本發明人基於多年研究開發與諸多實務經驗，提出一種照明裝置，以作為改善上述缺點之實現方式與依據。 In view of various problems of the prior art, the inventors have proposed a lighting device based on years of research and development and many practical experiences, as an implementation and basis for improving the above disadvantages.

請參閱第8圖所示，其係繪示本發明之照明裝置之第三較佳實施例之示意圖。與前述第二較佳實施例之不同處在於，調光元件3為包括複數個相對應之微透鏡陣列層31之實心元件，調光元件具有一厚度d。且集光元件2與調光元件3之間具有一距離B。若使用者欲調整照明裝置所呈現照明區域之大小樣態時，只需使用不同厚度d之調光元件，即可改變照明區域之大小樣態，以因應不同之使用狀況。 Referring to Figure 8, there is shown a schematic view of a third preferred embodiment of the illumination device of the present invention. The difference from the foregoing second preferred embodiment is that the dimming element 3 is a solid element including a plurality of corresponding microlens array layers 31, and the dimming element has a thickness d. And there is a distance B between the light collecting element 2 and the dimming element 3. If the user wants to adjust the size of the illumination area displayed by the illumination device, the size of the illumination area can be changed by using the dimming elements of different thicknesses d, so as to adapt to different usage conditions.
需特別說明，前述第二及第三較佳實施例之使用狀態，與第一較佳實施例之使用狀態相同，故於此不再贅述。此外，第二及第三較佳實施例亦可如第一較佳實施例，以複數個彼此並排設置，以增加照明面積，於此亦不再贅述。 It should be noted that the use states of the foregoing second and third preferred embodiments are the same as those of the first preferred embodiment, and thus will not be described again.

需特別說明，請再參閱第12圖所示，其係繪示本發明之照明裝置之第四較佳實施例之另一使用狀態示意圖。本發明之照明裝置之第四較佳實施例，亦可以複數個彼此並排設置，以增加照明面積。 Specifically, please refer to FIG. 12, which is a schematic view showing another use state of the fourth preferred embodiment of the lighting device of the present invention. The fourth preferred embodiment of the illumination device of the present invention may also be arranged in parallel with each other to increase the illumination area.
請參閱第13圖所示，其係繪示本發明之照明裝置之第五較佳實施例之示意圖。與前述第四較佳實施例之不同處在於，發光二極體1係為複數個。發光二極體1為例如紅光發光二極體、藍光發光二極體或混合紅光、藍光之發光二極體，前述僅為舉例但不為限制。導光元件5以及集光元件2設於發光二極體1與調光元件3之間，使得發光二極體1對應設於導光元件5之入光口51且調光元件3對應設於集光元件2之出光面22。而導光元件5之出光口52則與集光元件2之入光面21彼此對應設置。集光元件2與調光元件3之間具有一距離D。由於發光二極體1係為複數個，因此發光二極體之種類搭配變化性較高。例如發光二極體可為紅光發光二極體、藍光發光二極體或混合紅光及藍光之發光二極體之其一種或其多種組合，前述僅為舉例但不為限制。 Referring to Figure 13, there is shown a schematic view of a fifth preferred embodiment of the illumination device of the present invention. The difference from the foregoing fourth preferred embodiment is that the light-emitting diodes 1 are plural. The light-emitting diode 1 is, for example, a red light emitting diode, a blue light emitting diode, or a mixed red light or blue light emitting diode. The foregoing is by way of example only and not limitation. The light guiding element 5 and the light collecting element 2 are disposed between the light emitting diode 1 and the light adjusting element 3 such that the light emitting diode 1 is correspondingly disposed on the light entrance 51 of the light guiding element 5 and the light adjusting element 3 is correspondingly disposed on The light exit surface 22 of the light collecting element 2. The light exit opening 52 of the light guiding element 5 is disposed corresponding to the light incident surface 21 of the light collecting element 2. The light collecting element 2 and the dimming element 3 have a distance D therebetween. Since the number of the light-emitting diodes 1 is plural, the type of the light-emitting diodes is highly variable. For example, the light emitting diode may be one of a red light emitting diode, a blue light emitting diode, or a mixed red light and blue light emitting diode, or a plurality of combinations thereof, and the foregoing is merely an example and not a limitation.
需特別說明，前述第五較佳實施例之使用狀態，與第四較佳實施例之使用狀態相同，故於此不再贅述。此外，第五較佳實施例亦可如第四較佳實施例，以複數個彼此並排設置，以增加照明面積，於此亦不再贅述。 It should be noted that the state of use of the foregoing fifth preferred embodiment is the same as that of the fourth preferred embodiment, and therefore will not be further described herein. In addition, the fifth preferred embodiment can also be arranged in parallel with each other as in the fourth preferred embodiment to increase the illumination area, and details are not described herein again.
綜上所述，本發明之照明裝置至少具有下述之優點： In summary, the lighting device of the present invention has at least the following advantages:
1.提高了照明區域之照度，亦避免了光浪費：本發明之照明裝置以集光元件匯聚發光二極體所發出之光線，因此可提高照明區域之照度，亦避免了光浪費。 1. The illumination of the illumination area is improved, and the waste of light is also avoided: the illumination device of the present invention concentrates the light emitted by the light-emitting diode with the light collecting element, thereby improving the illumination of the illumination area and avoiding waste of light.
2.照明區域之光強度分佈均勻：本發明之照明裝置以調光元件或導光元件將發光二極體所發出之光線加以均勻化，因此照明區域之光強度分佈均勻。 2. Uniform light intensity distribution in the illumination area: The illumination device of the present invention homogenizes the light emitted by the light-emitting diode by the dimming element or the light guiding element, so that the light intensity distribution of the illumination area is uniform.
3.可改變照明區域之樣態，以因應不同之使用狀況：本發明之照明裝置可調整該些微透鏡陣列層之間之距離或集光元件與調光元件之距離，因此可因應不同之使用狀況而改變照明區域之樣態。 3. The illumination area can be changed to adapt to different usage conditions: the illumination device of the present invention can adjust the distance between the microlens array layers or the distance between the light collecting element and the dimming element, and thus can be used according to different uses. Change the state of the illuminated area.
4.照明面積可增加：本發明之照明裝置亦可複數個彼此並排設置，以增加照明面積。 4. The illumination area can be increased: the illumination device of the present invention can also be arranged side by side in plurality to increase the illumination area.
本發明之照明裝置相當適合用於照明植物，可依照植物之生長情況加以調整照明區域之樣態，亦可針對植物之發芽提供藍光加以照明，亦或針對植物之生長提供紅光加以照明。且可使植物獲得均勻且明亮之照明。前述用於照明植物僅為舉例但不為限制。 The illuminating device of the invention is quite suitable for illuminating plants, can adjust the state of the illumination area according to the growth condition of the plant, can provide blue light for germination of the plant, or provide red light for the growth of the plant. It also allows plants to achieve uniform and bright illumination. The foregoing for illuminating plants is by way of example only and not limitation.
以上所述僅為舉例性，而非為限制性者。任何未脫離本發明之精神與範疇，而對其進行之等效修改或變更，均應包含於後附之申請專利範圍中。 The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
