Description
本發明關於一種照明裝置及光學模組,特別是關於一種用於遠近光燈的照明系統,具有近光燈的補光的照明裝置及光學模組。 The present invention relates to an illuminating device and an optical module, in particular to an illuminating system used for a low-beam lamp, an illuminating device with a supplementary light of a low-beam lamp, and an optical module.
在習知的投射式的照明裝置下,當發光二極體(Light-emitting diode,LED)的光源相對緊密排列時,形成近光燈LED呈一列排列以及遠光燈LED呈一列排列。而在近光燈LED與遠光燈LED相對排列時,兩者發光面之間的間距通常介於0.3mm~0.7mm之間;因此,近光燈所投射出的光束所形成的光型與遠光燈所投射出的光束所形成的光型之間,會存在以下的問題: In the conventional projection type lighting device, when the light-emitting diode (LED) light sources are relatively closely arranged, the low beam LEDs are arranged in a row and the high beam LEDs are arranged in a row. When the low beam LED and the high beam LED are arranged oppositely, the distance between the light-emitting surfaces of the two is usually between 0.3mm and 0.7mm; therefore, the light pattern formed by the light beam projected by the low beam and The following problems exist between the light patterns formed by the beams projected by the high beams:
一、在透鏡較小的情況時(直徑大約<5cm),當近光燈LED所形成的光型的邊緣(即明暗截止線)對應到-0.57°時,遠光燈LED所形成的光型的亮區會朝上偏離,導致遠光燈LED所形成的光型的最亮點(即hot spot)不在原點(即HV點)上,而無法符合法規(如歐規UN ECE R112或R113)要求;或是當遠光燈LED所形成的光型的最亮點(即hot spot)對應到原點(即HV點)時,近光燈LED的所形成的光型的邊緣(即明暗截止線)無法對應到-0.57°時而無法符合法規(如歐規UN ECE R112或R113)的要求,即如圖1所示。 1. When the lens is small (about <5cm in diameter), when the edge of the light pattern formed by the low beam LED (that is, the cut-off line) corresponds to -0.57°, the light pattern formed by the high beam LED The bright area will deviate upwards, causing the brightest spot (hot spot) of the light pattern formed by the high beam LED to not be at the origin (ie HV point) and fail to comply with regulations (such as EU UN ECE R112 or R113) Requirements; or when the brightest point of the light pattern formed by the high beam LED (ie hot spot) corresponds to the origin (ie HV point), the edge of the light pattern formed by the low beam LED (ie the cut-off line) ) Can not correspond to -0.57° and cannot meet the requirements of regulations (such as EU UN ECE R112 or R113), as shown in Figure 1.
二、如圖2所示,當近光燈LED與遠光燈LED相對排列時,兩者發光面之間具有一定的間隙時,如間隙介於0.3mm~0.7mm之間,因此,近光 燈LED的所形成的光型與遠光燈LED所形成的光型之間,會有暗影區W(即亮度嚴重不足)的存在。 2. As shown in Figure 2, when the low beam LED and the high beam LED are arranged oppositely, there is a certain gap between the light-emitting surfaces of the two, such as the gap between 0.3mm and 0.7mm. Therefore, the low beam Between the light pattern formed by the lamp LED and the light pattern formed by the high beam LED, there will be a dark shadow area W (that is, a serious lack of brightness).

具體來說,根據圖31與圖5比較所示,本實施例所提供的照明裝置Z與前述第一實施例的照明裝置Z的差異在於,本實施例的照明裝置Z的光學模組D可包括第一導光單元D1,第一導光單元D1包括了第一入光面D11、第二入光面D12、第一出光面D13以及第二出光面D14。第一導光單元D1可為平行四邊形結構或四邊形結構,且第二入光面D12與第一出光面D13之間可形成第一預定夾角A1;其中,第一預定夾角A1可介於40~60度,第一預定夾角A1較佳可為45度。並且,第一入光面D11可平行於第一光源發光面110,或者,第一入光面D11約略平行於第一光源發光面110,並與第一光源發光面110之間具有1~30度的夾角。第一入光面D11可為一光學平面,但本發明不以第一入光面D11為平面為限,第一入光面D11也可為曲面或凹凸面。第一入光面D11與第一光源發光面110之間可具有第一預設間距C1;其中,第一預設間距C1可介於0.01~0.5mm,第一預設間距C1較佳可介於0.2~0.3mm。
Specifically, according to the comparison between FIG. 31 and FIG. 5, the difference between the illuminating device Z provided by this embodiment and the illuminating device Z of the aforementioned first embodiment is that the optical module D of the illuminating device Z of this embodiment can be It includes a first light guide unit D1, and the first light guide unit D1 includes a first light-incident surface D11, a second light-incident surface D12, a first light-emitting surface D13, and a second light-emitting surface D14. The first light guide unit D1 can be a parallelogram structure or a quadrilateral structure, and a first predetermined included angle A1 can be formed between the second light incident surface D12 and the first light exit surface D13; wherein, the first predetermined included angle A1 can be between 40~ 60 degrees, the first predetermined included angle A1 may preferably be 45 degrees. In addition, the first light incident surface D11 may be parallel to the first light
而透鏡模組2可具有焦點21以及焦距,焦點21不在第一光源發光面110上,其中以位於第二光源發光面120的邊界E內,或位於第二發光單元12的光線朝透鏡模組2射出的區域內,其中以較靠近第一發光單元11的區域為佳(如前述第四實施例以及圖32所示),而透鏡模組2的焦距可為透鏡模組2的入射面200到焦點21之間的距離。焦平面210可平行於第一光源發光面110,如圖31所示;或者,焦平面210約略平行於第一光源發光面110,如圖32所示,焦平面210與第一光源發光面110之間也可具有1~30度的夾角(類似前述第一傾斜夾角B1,如圖6所示,在此不再特別標示)。並且,透鏡模組2的入射面200與第一光源發光面110之間的距離可大於透鏡模組2的焦距,但不以此為限;也就是說,焦平面210與第一光源發光面110之間具有一第二預設間距C2,
第二預設間距C2介於0.2~5mm之間,其中以0.5~1.5mm為佳,且以1.2mm為更佳,但本發明不以此為限。
The
因此,在本發明的照明裝置Z投射出光束時,當第一導光單元D1沒有完全將第一光源發光面110完全罩住時(本發明不以此為限),第一發光單元11藉由第一光源發光面110所產生的第一光束L1,其中一部份(即遠離透鏡光軸22的部份)不會經由光學模組D的折射,而直接進入透鏡模組2,而該部份的第一光束L1由透鏡模組2投出後,會落在明暗截線以下,遠離明暗截止線的區域;而另一部份的第一光束L1即位於第一光源發光面110中較靠近光軸22的發光點,會經由光學模組D的第一導光單元D1的折射(如圖33及圖34所示)而改變路線,再進入透鏡模組2中,進而使得另一部份的第一光束L1由透鏡模組2投出後,可落在所形成的光型的邊緣(即明暗截止線),且落在HV點以下的一固定角度範圍上,此一固定角度範可為-0.57°±0.3°,但本發明不以此為限。 Therefore, when the lighting device Z of the present invention projects a light beam, when the first light guide unit D1 does not completely cover the light-emitting surface 110 of the first light source (the present invention is not limited to this), the first light-emitting unit 11 uses A part of the first light beam L1 generated by the light-emitting surface 110 of the first light source (that is, the part far away from the optical axis 22 of the lens) will directly enter the lens module 2 without being refracted by the optical module D. After being projected by the lens module 2, part of the first light beam L1 will fall below the cut-off line of light and dark, and away from the area of the cut-off line; while the other part of the first light beam L1 is located in the light-emitting surface 110 of the first light source The light emitting point closer to the optical axis 22 will change the route through the refraction of the first light guide unit D1 of the optical module D (as shown in Figure 33 and Figure 34), and then enter the lens module 2 to make another After being projected by the lens module 2, part of the first light beam L1 can fall on the edge of the formed light pattern (ie the cut-off line), and fall on a fixed angle range below the HV point. This fixed angle The range can be -0.57°±0.3°, but the present invention is not limited to this.
進一步來說,經過第一導光單元D1的另一部份的第一光束L1的光線行經的路徑,大致可分為兩種不同的路徑,分別可為全反射路徑或非全反射路徑,即另一部份的第一光束L1可分為屬於全反射路徑的第一光束L11以及屬於非全反射路徑的第一光束L12。為使圖示清晰可辨,圖33只標示全反射路徑的第一光束L11,其他未標示的為L12。配合圖33所示,第一光束L11在全反射路徑中,先由第一光源發光面110投射至第一入光面D11,並經由第一入光面D11的第一次折射而進入第一導光單元D1後,再經由第二出光面D14的第一次全反射以及第二入光面D12的第兩次全反射後,最後經由第一出光面D13的第二次折射而射出至第一導光單元D1的外部。換句話說,第一光源發光面110所產生的第一光束L11,從進入第一導光單元D1之後,要經過兩次折射以及兩次全反射之後,第一光束L11才會離開第一導光單元D1。接下來,由
第一出光面D13折射出的第一光束L11經由透鏡模組2的投射而在測試屏幕上所形成的光型(如圖9所示)的邊緣(即明暗截止線)可落在HV點以下的一固定角度範圍上,此一固定角度範圍可為-0.57°±0.3°,但本發明不以此為限。需要說明的事,要落在明暗截止線上的光線,需要經過兩次的折射及兩次的全反射。
Furthermore, the path traveled by the first light beam L1 passing through another part of the first light guide unit D1 can be roughly divided into two different paths, which can be a total reflection path or a non-total reflection path, namely The other part of the first light beam L1 can be divided into a first light beam L11 belonging to a total reflection path and a first light beam L12 belonging to a non-total reflection path. In order to make the figure clearly recognizable, FIG. 33 only marks the first light beam L11 of the total reflection path, and other unmarked light beams L12. As shown in FIG. 33, the first light beam L11 is first projected from the light-emitting
再請配合圖34所示,第一光束L12在非全反射的路徑中,先由第一光源發光面110投射至第一入光面D11與第二入光面D12,並經由第一入光面D11與第二入光面D12的第一次折射而進入第一導光單元D1後,再經由第一出光面D13與第二出光面D14的第二次折射而射出至第一導光單元D1的外部。換句話說,第一光束L1從進入第一導光單元D1後,經過兩次的折射,才會離開第一導光單元D1,接著,再經由透鏡模組2而投射到測試屏幕上所形成的光型(如圖9所示),其明暗截止線會落在HV點以下的一固定角度範圍,此固定角度範圍可為-0.57°±0.3°,但本發明不以此為限。
As shown in FIG. 34, the first light beam L12 is first projected from the light-emitting

Further, the first light incident surface D11 may be parallel to the first light output surface D13, and the second light incident surface D12 may be parallel to the second light output surface D14; wherein the thickness H of the first light guide unit D1 may be between 0.2 and 1.0 mm, the thickness H of the first light guide unit D1 may preferably be 0.5 to 0.6 mm. For example, as shown in FIG. 31, the first light-incident surface D11 and the first light-emitting surface D13 may be parallel to each other. However, as shown in FIG. 32, the first light-incident surface D11 may also be approximately parallel to the first light-emitting surface D13, and have a second inclined angle B2 of 1 to 15 degrees with the first light-emitting surface D13. The second light-incident surface D12 and the second light-emitting surface D14 may be parallel to each other, but the second light-incident surface D12 may also be approximately parallel to the second light-emitting surface D14, and has a first light-emitting surface of 1 to 15 degrees between it and the second light-emitting surface D14.

更進一步地,第二入光面D12與第一出光面D13的相接位置P可

Please also refer to FIGS. 1 to 35.

It is worth noting that in this embodiment, the
具體來說,配合圖25、圖30及圖31所示,本發明的光源模組1還進一步可包括至少一個第二發光單元12,第二發光單元12可為發光二極體
(Light-emitting diode,LED),且第二發光單元12可具有第二光源發光面120;其中,在本實施例中,第二發光單元12係以兩個作為示例,但不以此為限。多個第一發光單元11可位於多個第二發光單元12的上方,且第二光源發光面120與第一光源發光面110位於同一個水平面上,但本發明不以此為限;其中,第一發光單元11可為近光燈的發光源,第二發光單元12可為遠光燈的發光源,但不以此為限。透鏡模組2還可具有光軸22,光軸22可通過透鏡模組2的中心或中心附近,並且,光軸22可通過透鏡模組2的焦點21且垂直於第二光源發光面120,光軸22可通過第二光源發光面120且較靠近第一光源發光面110的位置,但本發明不以光軸22可垂直於第二光源發光面120為限。其中,當第二發光單元12數量為一個的時候,光軸22對應於第二光源發光面120上且位於第二發光單元12兩側之間的正中間位置上;而當第二發光單元12數量為兩個的時候,光軸22對應於兩個第二光源發光面120之間的位置且位於兩個第二發光單元12之間的正中間位置上。

因此,配合圖31及圖37所示,在第二光源發光面120產生第二光束L2時,其中一部份的第二光束L2不會經由光學模組D的折射,而直接進入透鏡模組2,另一部份的第二光束L2會經由光學模組D的第一導光單元D1的折射(如圖37所示,圖中的發光點僅為第二光源發光面120上緊鄰於光軸的其中一個發光點)而改變路線,再進入透鏡模組2中。最後,其中一部份的第二光束L2與另一部份的第二光束L2由透鏡模組2射出後,會形成遠光燈的光型,並且遠光燈LED所形成的光型的最亮點會在原點(即HV)上。而第一發光單元11(即近光燈LED)所形成的光型的邊緣(即明暗截止線)可成功的對應到HV點以下(-0.57°±0.3°),並且同時還能減少近光燈LED與遠光燈LED緊密相對排列時(第一光源發光面110與第二光源發光面120之間具有一定的間隙時),近光燈光型與遠光燈LED光型之間會有暗影區的情形(如圖20所示)。
