Description
本案係有關一種導光裝置，尤指一種用於發光二極體之導光裝置，該導光裝置具有遮光罩的設置，使得相鄰設置之導光柱不致因發光二極體光線折射及漫射而造成指示燈號的辨識混淆情事。
The present invention relates to a light guiding device, and more particularly to a light guiding device for a light emitting diode, wherein the light guiding device has a hood arrangement such that adjacently disposed light guiding columns are not refracted and diffused by the light emitting diode light. The identification of the indicator number is confusing.
按發光二極體(LED)作為顯示用途，已行之有年，即以吾人常見之電子、電氣或機械設備為例，顯示面板背後常見發光二極體的設置。當然，依規格或設計之不同，發光二極體亦有作為照明的用途。According to the light-emitting diode (LED) for display purposes, it has been a year, that is, taking the common electronic, electrical or mechanical equipment of our people as an example, the setting of the common light-emitting diode behind the display panel. Of course, depending on the specification or design, the light-emitting diodes are also used for illumination.
如圖1所示，乃習知導光裝置之立體圖，該導光裝置包括一導光座1，該導光座1底部具有一基座11，該基座11底面兩側伸出一對扣鉤12，而頂面則平行地伸出至少兩根導光柱13，另於該基座11底面對應各導光柱13位置開設一容置槽14。As shown in FIG. 1 , it is a perspective view of a conventional light guiding device. The light guiding device includes a light guiding seat 1 . The bottom of the light guiding base 1 has a base 11 , and a pair of buckles protrude from both sides of the bottom surface of the base 11 . The hook 12 has a top surface extending in parallel with at least two light guiding columns 13 , and a receiving groove 14 is defined in the bottom surface of the base 11 corresponding to each of the light guiding columns 13 .
如圖2所示，係將該導光裝置結合於印刷電路板之剖面圖，該印刷電路板3表面以表面黏著技術耦接三顆片狀發光二極體(LED) 31；而該導光座1則利用該基座11底面兩側之一對扣鉤12扣接於該印刷電路板3預設之板孔32內，使該導光座1固設於該印刷電路板3上，其中該基座11底面設置的各容置槽14各自供一LED 31的容置。由於該導光座1係以透明高分子材料所製成，方能達成導光效果。所以，當其中第一LED 31被點亮後，其正常狀態是光線進入該LED 31上方之第一導光柱13內，並將光線傳導至第一導光柱31的自由端，以利於指示。惟前述部份光線因折射及漫射作用會進入相鄰第二導光柱13’內，並在該第二導光柱13’的自由端顯示出部份光線。此舉，使得該等第一、第二導光柱13、13’的自由端會分別傳導出亮度具有差異的指示燈號，而造成使用者對指示燈號的辨識混淆問題，而亟待改善。
As shown in FIG. 2, the light guiding device is coupled to a cross-sectional view of a printed circuit board, and the surface of the printed circuit board 3 is coupled to three chip-shaped light emitting diodes (LEDs) 31 by surface bonding technology; The seat 1 is fastened to the predetermined hole 32 of the printed circuit board 3 by one of the two sides of the bottom surface of the base 11, so that the light guide base 1 is fixed on the printed circuit board 3, wherein Each of the accommodating grooves 14 provided on the bottom surface of the susceptor 11 is provided for receiving an LED 31. Since the light guiding seat 1 is made of a transparent polymer material, the light guiding effect can be achieved. Therefore, when the first LED 31 is illuminated, its normal state is that light enters the first light guiding column 13 above the LED 31, and conducts light to the free end of the first light guiding column 31 to facilitate indication. However, some of the light rays enter into the adjacent second light guiding column 13' due to refraction and diffusion, and a part of the light is displayed at the free end of the second light guiding column 13'. In this way, the free ends of the first and second light guiding columns 13, 13' respectively conduct the indicator numbers with different brightness, which causes the user to confuse the identification of the indicator numbers, and needs to be improved.
本案主要目的在於提供一種用於發光二極體之導光裝置，其係在該導光座之各容置槽內結合不透光的遮光罩，以便改善習知導光柱因光線反射作用而造成指示燈號的辨識混淆問題外，同時能將LED的光線集中在單一導光柱內，且能避免受到其他LED光線的影響等優點。The main purpose of the present invention is to provide a light guiding device for a light emitting diode, which incorporates an opaque hood in each receiving groove of the light guiding seat, so as to improve the light guiding effect of the conventional light guiding column. In addition to the confusion of the identification of the indicator light, the light of the LED can be concentrated in a single light guide column, and the influence of other LED light can be avoided.
為達成前述之目的，本案所採取之技術手段係提供一種用於發光二極體之導光裝置，其包括一導光座，其為透明體，該導光座底部具有一基座，該基座底面兩側伸出至少一對扣鉤，而頂面則平行地伸出至少兩根導光柱，且該基座底面對應各導光柱位置分別開設一容置槽；以及至少一遮光罩，其具有一不透光顏色且能套設於各容置槽內之矩形框體，各框體位於各導光柱位置縱向設有一供發光二極體容置之通孔，且各框體前、後側突設至少一對能扣接於該基座前、後緣之卡鉤，使各遮光罩牢固地定位於各容置槽內。

To further reveal the specific technical content of this case, please first refer to the schema, in which:
Figure 1 is a perspective view of a conventional light guiding device;
2 is a cross-sectional view of a conventional light guiding device coupled to a printed circuit board;
3 and FIG. 4 are exploded perspective views of two different viewing angles of the light guiding device of the present invention;
Figure 5 is a perspective view of the light guiding device of the present invention; and Figure 6 is a cross-sectional view of the light guiding device incorporated in the printed circuit board.
如圖3及圖4所示，基本上，本案導光裝置包括一導光座1及至少一遮光罩2。As shown in FIG. 3 and FIG. 4, basically, the light guiding device of the present invention comprises a light guiding seat 1 and at least one light shielding cover 2.
導光座1為前述習知構件，其係以透明高分子材料，例如壓克力一體射出成型。該導光座1底部具有一基座11的設置，該基座11底面兩側伸出至少一對扣鉤12，而頂面則平行地伸出至少兩根導光柱13，另於該基座11底面對應各導光柱13位置分別開設一容置槽14，而該導光座1異於習知構件技術在於，各容置槽14前、後側之其中一開口端縱向突伸一小段凸緣15。The light guide holder 1 is a conventional member which is integrally molded by a transparent polymer material such as acryl. The bottom of the light guide base 1 has a pedestal 11 , and the bottom surface of the base 11 protrudes from at least one pair of hooks 12 , and the top surface protrudes in parallel with at least two light guide columns 13 , and the base The bottom surface of each of the light guiding columns 13 is respectively provided with a receiving groove 14 , and the light guiding seat 1 is different from the conventional component technology in that one of the front ends of the front and rear sides of each receiving groove 14 protrudes longitudinally by a small flange. 15.
遮光罩2為不透光顏色，例如黑色高分子材料所製成，其具有一矩形框體21，該矩形框體尺寸等同於容置槽14，以便可套設於容置槽14內。該框體14位於該導光柱13位置縱向設有一通孔22，以便容置發光二極體(LED)。為使該遮光罩2得以結合於該導光座1，而不致脫落，因此，該框體21前、後側突設至少一對卡鉤23，較佳為該框體21前、後側對角端突設至少一對卡鉤23，並利用各對卡鉤23扣接於基座11前、後緣，使各遮光罩2套設於容置槽14內，並扣接於基座11，以形成牢固地定位關係。The hood 2 is made of a opaque color, for example, a black polymer material, and has a rectangular frame 21 having a size equal to that of the accommodating groove 14 so as to be sleeved in the accommodating groove 14. The frame 14 is vertically disposed at a position of the light guiding rod 13 to provide a through hole 22 for accommodating a light emitting diode (LED). In order to allow the hood 2 to be coupled to the light guide holder 1 without being detached, at least a pair of hooks 23 are protruded from the front and rear sides of the frame body 21, preferably the front and rear sides of the frame body 21 are opposite. At least one pair of hooks 23 are protruded from the corner ends, and the front and rear edges of the base 11 are fastened by the respective pairs of hooks 23, so that the hoods 2 are sleeved in the accommodating slots 14 and fastened to the pedestal 11 To form a firm positioning relationship.
尤有進者，各遮光罩2頂面對應容置槽14內之凸緣15位置則設有凹槽24，以便與凸緣15形成對接關係，以提供各遮光罩2安裝時的方向性，例如當該遮光罩2頂面平面抵接於容置槽14之凸緣時，將會使得同一邊(前緣)之卡鉤23無法扣接於基座11，使得該遮光罩2形成非對接關係的傾斜狀。In particular, the top surface of each hood 2 is provided with a groove 24 corresponding to the flange 15 in the accommodating groove 14 so as to form abutting relationship with the flange 15 to provide directionality when each hood 2 is installed. For example, when the top surface of the hood 2 abuts against the flange of the accommodating groove 14, the hook 23 of the same side (leading edge) cannot be fastened to the pedestal 11, so that the hood 2 is non-docking. The slope of the relationship.
如圖5所示，係將三個遮光罩2分別接裝於該導光座1底部個容置槽14內的立體圖，亦即本案導光裝置之成品圖。As shown in FIG. 5, three hoods 2 are respectively attached to the bottom accommodating grooves 14 of the light guiding seat 1, which is a finished view of the light guiding device of the present invention.
如圖6所示，係將該導光裝置結合於印刷電路板之剖面圖，該印刷電路板3表面具有三顆片狀LED 31；該導光座1則利用該基座11底面兩側之一對扣鉤12扣接於該印刷電路板3預設之板孔32內，使得該導光座1固設於該印刷電路板3上，其中各容置槽14各自套設一遮光罩2之矩形框體21，且各框體21之通孔22內供一LED 31的容置。As shown in FIG. 6, the light guiding device is combined with a cross-sectional view of a printed circuit board having three chip LEDs 31 on the surface thereof; the light guiding seat 1 is formed on both sides of the bottom surface of the base 11. A pair of hooks 12 are fastened into the predetermined hole 32 of the printed circuit board 3, so that the light guide base 1 is fixed on the printed circuit board 3, wherein each of the receiving slots 14 is sleeved with a light shield 2 The rectangular frame body 21 is provided with an LED 31 in the through hole 22 of each frame body 21.
當一LED 31點亮後，其光線受到該不透光框體21的遮蔽作用，而只能通過通孔22，並朝著該LED 31上方的導光柱13行進，並將光線傳導至該導光柱31的自由端，以利於指示。When an LED 31 is turned on, its light is shielded by the opaque frame 21, and can only pass through the through hole 22 and travel toward the light guiding column 13 above the LED 31, and conduct the light to the guide. The free end of the beam 31 is intended to facilitate the indication.
所以，經由本案之實施，其所增益的功效在於，該導光座之容置槽供不透光遮光罩結合後，使被遮光罩之框體包覆的LED所產生的光線只能通過通孔，並朝著該LED上方的導光柱行進，而不致因導光座為透明狀，而讓光線因反射及漫射作用而形成透光的困擾，同時能將光線集中在單一導光柱中，從而解決辨識混淆的問題。尤有進者，因各LED都被一個遮光罩所包覆，以避免多個LED所造成混光的問題，堪稱為該項技術領域之一大突破。Therefore, through the implementation of the present case, the gain of the light-guiding seat is that the illuminating groove of the light-guiding seat is combined with the opaque hood, so that the light generated by the LED covered by the frame of the hood can only pass through The hole travels toward the light guiding column above the LED, so that the light guiding seat is transparent, and the light causes the light to be transmitted due to reflection and diffusion, and the light can be concentrated in a single light guiding column. Thereby solving the problem of identifying confusion. Especially in advance, because each LED is covered by a hood to avoid the problem of light mixing caused by multiple LEDs, it is a breakthrough in this technology field.
本案所揭示者，乃較佳實施例之一種，舉凡局部之變更或修飾而源於本案之技術思想而為熟習該項技藝之人所易於推知者，俱不脫本案之專利權範疇。
