Description

鋼琴燈piano light

本發明是有關於一種燈具，且特別是有關於一種鋼琴燈。The present invention relates to a lamp, and in particular to a piano lamp.

愈來愈多孩童開始學習鋼琴，家長們也因為孩童練習鋼琴時需要長時間盯著琴譜與琴鍵而擔憂練琴環境的照明度是否足夠，因此專為照明鋼琴的鋼琴燈也隨之誕生。通常，鋼琴的琴鍵為呈長方形排列，總長約123cm，總寬約15cm。More and more children are starting to learn piano, and parents are worried about whether the lighting in the practice environment is sufficient because children need to stare at the music scores and keys for a long time when practicing piano. Therefore, piano lights specially designed to illuminate pianos have also been born. Usually, the keys of a piano are arranged in a rectangular shape, with a total length of about 123cm and a total width of about 15cm.

一般的讀寫作業檯燈無法提供如此扁長的照明範圍，因此對應鋼琴的邊緣處會有兩側偏暗的疑慮，但中間又過亮，整體照度分布不均勻，反而造成使用者視覺疲勞。Ordinary reading and writing desk lamps cannot provide such a long and flat lighting range, so the edges of the piano may be dark on both sides, but the middle is too bright, and the overall illumination distribution is uneven, which in turn causes visual fatigue for the user.

因此，有別於一般檯燈，目前常見的鋼琴燈通常是以長條狀的燈具來呈現，以保證鋼琴的兩邊緣側能夠有足夠的照度。Therefore, unlike ordinary desk lamps, currently common piano lamps are usually presented as long strip lamps to ensure sufficient illumination on both edges of the piano.

然而，多數鋼琴燈以效率較佳的LED為發光元件，而LED具備發光指向性，因此與傳統燈泡相比，在產生同樣的光通量時，輝度會非常高，造成局部刺眼眩光等現象。However, most piano lamps use more efficient LEDs as light-emitting elements, and LEDs have light-emitting directivity. Therefore, compared with traditional light bulbs, when producing the same luminous flux, the brightness will be very high, causing local dazzling glare and other phenomena.

本發明提供一種能夠提供足夠照光範圍及照度的鋼琴燈。The invention provides a piano lamp that can provide sufficient illumination range and illumination.

本發明的鋼琴燈適於朝向鋼琴的多個琴鍵照光，包括光源以及長條形透光組件。長條形透光組件具有入光面以及出光面，入光面朝向光源，出光面朝向琴鍵出光，其中出光面由一平面及兩凸面共構，且沿著長條形透光組件的長度方向，平面位於凸面之間。The piano lamp of the present invention is suitable for illuminating multiple keys of the piano, and includes a light source and a long light-transmitting component. The elongated light-transmitting component has a light-incoming surface and a light-emitting surface. The light-incoming surface faces the light source, and the light-emitting surface emits light toward the keys. The light-emitting surface is composed of a flat surface and two convex surfaces, and is along the length direction of the elongated light-transmitting component. , the plane is located between the convex surfaces.

在本發明的一實施例中，上述的鋼琴燈還包括兩反射片，反射片設置在光源的兩側並接合於長條形透光組件，其中反射片呈拋物面。In one embodiment of the present invention, the above-mentioned piano light further includes two reflective sheets. The reflective sheets are arranged on both sides of the light source and joined to the elongated light-transmitting component, wherein the reflective sheets are in the shape of a paraboloid.

在本發明的一實施例中，上述的鋼琴燈還包括位於長條形透光組件及光源之間的擴散片。In an embodiment of the present invention, the above-mentioned piano light further includes a diffusion sheet located between the elongated light-transmitting component and the light source.

在本發明的一實施例中，上述的長條形透光組件的長度範圍介於54cm至66cm。In an embodiment of the present invention, the length of the elongated light-transmitting component ranges from 54 cm to 66 cm.

在本發明的一實施例中，其中沿著長條形透光組件的長度方向，兩凸面與平面的比例為1:2:1。In an embodiment of the present invention, along the length direction of the elongated light-transmitting component, the ratio of the two convex surfaces to the flat surface is 1:2:1.

在本發明的一實施例中，其中沿著長條形透光組件的一厚度方向，長條形透光組件於凸面處的厚度為2.5mm。In one embodiment of the present invention, along a thickness direction of the elongated light-transmitting component, the thickness of the elongated light-transmitting component at the convex surface is 2.5 mm.

基於上述，本發明的鋼琴燈相較於習知的鋼琴燈具備了一種新穎的架構，因此能夠提供較佳的照光範圍及照度。Based on the above, the piano lamp of the present invention has a novel structure compared with the conventional piano lamp, and therefore can provide a better illumination range and illumination intensity.

圖1為本實施例的鋼琴燈朝向鋼琴的琴鍵照光的示意圖。圖2為圖1的鋼琴燈的分解示意圖，而圖3為圖2的鋼琴燈組裝後的剖面示意圖。請同時參考圖1、圖2及圖3。本實施例的鋼琴燈1相較於習知的鋼琴燈提供了一種新穎的架構，因此相較於習知的鋼琴燈能夠提供較佳的照光範圍及照度，讓使用者能夠以優良的環境彈奏或練習鋼琴。Figure 1 is a schematic diagram of the piano light according to this embodiment illuminating the keys of the piano. FIG. 2 is an exploded schematic view of the piano light of FIG. 1 , and FIG. 3 is a cross-sectional schematic view of the assembled piano light of FIG. 2 . Please refer to Figure 1, Figure 2 and Figure 3 at the same time. Compared with the conventional piano light, the piano light 1 of this embodiment provides a novel structure. Therefore, compared with the conventional piano light, it can provide a better illumination range and illumination, allowing the user to play in an excellent environment. Play or practice piano.

本實施例的鋼琴燈1包括光源12以及長條形透光組件14。長條形透光組件14具有入光面141以及出光面142，入光面141朝向光源12，出光面142朝向琴鍵3出光，且出光面142由一平面142a及兩凸面142b共構，且沿著長條形透光組件14的長度方向，平面142a位於兩凸面142b之間。The piano light 1 of this embodiment includes a light source 12 and a strip-shaped light-transmitting component 14. The elongated light-transmitting component 14 has a light-incident surface 141 and a light-emitting surface 142. The light-incident surface 141 faces the light source 12, and the light-emitting surface 142 emits light toward the keys 3. The light-emitting surface 142 is composed of a flat surface 142a and two convex surfaces 142b, and is formed along the Along the length direction of the elongated light-transmitting component 14, the flat surface 142a is located between the two convex surfaces 142b.

在本實施例中，光源12為LED光源，且可以使用單一LED點光源的方式實現，或是以多個LED點光源來實現。選用多個LED點光源相較於使用單一LED點光源的優點在於：能夠避免單一LED點光源容易形成黑影而造成暗部的情形。In this embodiment, the light source 12 is an LED light source, and can be implemented as a single LED point light source, or as multiple LED point light sources. The advantage of using multiple LED point light sources compared to using a single LED point light source is that it can avoid the situation where a single LED point light source easily forms black shadows and causes dark parts.

此外，鋼琴燈1還包括位於長條形透光組件14及光源12之間的擴散片16。具體地說，由於LED光源具備指向性，容易造成局部高輝度而讓使用者感覺得強烈刺眼的眩光，因此在光源12及長條形透光組件14之間設置擴散片16以能夠將LED光源的點光源經由擴散片16而形成面光源，以增進鋼琴燈1的出光均勻度。In addition, the piano light 1 also includes a diffusion sheet 16 located between the elongated light-transmitting component 14 and the light source 12 . Specifically, because the LED light source has directivity, it is easy to cause local high brightness and make the user feel strong and dazzling glare. Therefore, a diffusion sheet 16 is provided between the light source 12 and the elongated light-transmitting component 14 to separate the LED light source. The point light source forms a surface light source through the diffusion sheet 16 to improve the light uniformity of the piano lamp 1.

附帶一提，藉由擴散片16的設置而能夠使得LED光源的點光源經由擴散片16而形成面光源，因此長條形透光組件14的入光面141可以平面實施。在其他的實施例中，也可以考慮在不使用擴散片16的情況下而在長條形透光組件14的入光面141處設置微結構或者使入光面141具有表面粗糙度，也同樣可以達到設置擴散片16的功效。或者，也可以是將擴散片16與長條形透光組件14形成為一體結構，且擴散片16的出光面142朝向琴鍵3。Incidentally, the arrangement of the diffuser sheet 16 allows the point light source of the LED light source to form a surface light source through the diffuser sheet 16. Therefore, the light incident surface 141 of the elongated light-transmitting component 14 can be implemented as a planar surface. In other embodiments, it is also possible to consider arranging microstructures on the light incident surface 141 of the elongated light transmitting component 14 or providing the light incident surface 141 with surface roughness without using the diffusion sheet 16 , and the same is true. The effect of setting the diffuser 16 can be achieved. Alternatively, the diffusion sheet 16 and the elongated light-transmitting component 14 may be formed into an integrated structure, with the light-emitting surface 142 of the diffusion sheet 16 facing the keys 3 .

此外，上述的鋼琴燈1還包括兩反射片18，反射片18設置在光源12的兩側並接合於長條形透光組件14，其中反射片18呈拋物面，以將光源12發射至反射片18的光收攏並反射至長條形透光組件14。In addition, the above-mentioned piano lamp 1 also includes two reflective sheets 18. The reflective sheets 18 are disposed on both sides of the light source 12 and joined to the elongated light-transmitting component 14. The reflective sheet 18 is in the shape of a paraboloid to emit the light source 12 to the reflective sheet. The light from 18 is gathered and reflected to the elongated light-transmitting component 14 .

附帶一提，長條形透光組件14的長度範圍可介於54cm至66cm，而擴散片16的厚度範圍可為0.4mm~0.6mm。此外，沿著長條形透光組件14的長度方向(即X方向)，兩凸面142b與平面142a的比例為1:2:1。Incidentally, the length of the strip-shaped light-transmitting component 14 can range from 54cm to 66cm, and the thickness of the diffusion sheet 16 can range from 0.4mm to 0.6mm. In addition, along the length direction of the elongated light-transmitting component 14 (ie, the X direction), the ratio of the two convex surfaces 142b to the flat surface 142a is 1:2:1.

以本實施例而言，長條形透光組件14的長度為60cm，且沿著長條形透光組件14的長度方向，位於平面142a的一側的凸面142b的長度D2為15cm，平面142a的長度D1為30cm，位於平面142a的另一側的凸面142b的長度D2為15cm。另外，本實施例中的擴散片16的厚度T1為0.5mm。In this embodiment, the length of the elongated light-transmitting component 14 is 60 cm, and along the length direction of the elongated light-transmitting component 14, the length D2 of the convex surface 142b located on one side of the plane 142a is 15 cm, and the plane 142a The length D1 is 30cm, and the length D2 of the convex surface 142b located on the other side of the plane 142a is 15cm. In addition, the thickness T1 of the diffusion sheet 16 in this embodiment is 0.5 mm.

再者，沿著長條形透光組件14的厚度方向(即Y方向)，長條形透光組件14於凸面142b處的厚度T2為2.5mm，而於平面142a處的厚度T3小於2.5mm，例如是0.5mm~2mm，且較佳為0.5mm。Furthermore, along the thickness direction of the elongated light-transmitting component 14 (ie, the Y direction), the thickness T2 of the elongated light-transmitting component 14 at the convex surface 142b is 2.5 mm, and the thickness T3 at the flat surface 142a is less than 2.5 mm. , for example, 0.5mm~2mm, and preferably 0.5mm.

圖4為長條形透光組件的示意圖，其中長條形透光組件14的出光面142朝上且入光面141朝下以突顯出凸面142b。請同時參考圖1及圖4，上述的鋼琴燈1的長條形透光組件14的中間位置為平面142a，且平面142a對應使用者，其中對應平面142a處用以提供使用者充足的照度及以較寬廣的光束角照明範圍來照亮琴譜。此外，長條形透光組件14的兩側設置凸面142b，利用凸面142b來聚光而讓凸面142b處提供較小的光束角提供照明，以增加琴鍵3兩側的照度。FIG. 4 is a schematic diagram of a long light-transmitting component, in which the light-emitting surface 142 of the long-shaped light-transmitting component 14 faces upward and the light-incident surface 141 faces downward to highlight the convex surface 142b. Please refer to Figures 1 and 4 at the same time. The middle position of the strip-shaped light-transmitting component 14 of the piano light 1 is a plane 142a, and the plane 142a corresponds to the user. The corresponding plane 142a is used to provide the user with sufficient illumination and Illuminate the music score with a wider beam angle illumination range. In addition, convex surfaces 142b are provided on both sides of the elongated light-transmitting component 14. The convex surfaces 142b are used to collect light and provide illumination with a smaller beam angle, thereby increasing the illumination on both sides of the keyboard 3.

附帶一提，平面142a與凸面142b之間以緩坡連接，以避免平面142a與凸面142b之間的連接處出現斷點而影響光學效果。Incidentally, the flat surface 142a and the convex surface 142b are connected with a gentle slope to avoid breakpoints at the connection between the flat surface 142a and the convex surface 142b, which may affect the optical effect.

綜上所述，在本發明的鋼琴燈中，長條形透光組件具有新穎的結構設計，其中長條形透光組件的中間部分為平面以提供使用者充足的照度及以較寬廣的光束角照明範圍來照亮琴譜，而兩側部分設置凸面以利用凸面來聚光而讓凸面處以較小的光束角來提供照明，進而增加琴鍵兩側的照度。因此，鋼琴燈不論是對應琴鍵的中間部分或是兩側部分都能提供良好的照光範圍及照明亮度。To sum up, in the piano light of the present invention, the elongated light-transmitting component has a novel structural design, in which the middle part of the elongated light-transmitting component is flat to provide the user with sufficient illumination and a wider beam. The angular illumination range is used to illuminate the piano score, and the convex surfaces are provided on both sides to use the convex surface to concentrate light and provide illumination with a smaller beam angle at the convex surface, thus increasing the illumination on both sides of the keys. Therefore, the piano light can provide a good lighting range and lighting brightness whether it is corresponding to the middle part or both sides of the piano keys.
