Abstract
Description
本創作是有關一種導光元件,尤其是一種用於導引頭燈的發光元件發出的光線的導光透鏡以及具此導光透鏡的交通工具頭燈。The present invention relates to a light guiding element, in particular to a light guiding lens for guiding light emitted by a light emitting element of a headlight and a vehicle headlight having the light guiding lens.
近年來,交通工具的頭燈已逐漸地採用發光二極體作為光源。In recent years, headlights for vehicles have gradually adopted light-emitting diodes as light sources.
應用於交通工具的頭燈時,發光二極體必須搭配適當的導光元件,才能使頭燈發出所需的光形及角度。發光二極體可配置於導光元件的一個表面外,導光元件更具有一個反射面以反射發光二極體所發出的光線以及一個出光面以出射被反射面所反射的光線。When applied to a headlight of a vehicle, the light-emitting diode must be equipped with an appropriate light guiding element to make the headlight emit the desired light shape and angle. The light emitting diode can be disposed outside a surface of the light guiding element, and the light guiding element further has a reflecting surface to reflect the light emitted by the light emitting diode and a light emitting surface to emit the light reflected by the reflecting surface.
習知技術的導光元件的反射面是電鍍反射層而形成,如此將增加導光元件的製作複雜度,進而導致製造成本較高。The reflective surface of the light guiding element of the prior art is formed by plating a reflective layer, which increases the complexity of fabrication of the light guiding element, which in turn leads to higher manufacturing costs.
另外,習知技術的導光元件的反射面在任一截面中僅具單一的曲率,且須以此曲率向上延伸至一定的高度才能接收到所對應截面中發光二極體大部分的光線,這造成了導光元件必須具有對應的厚度,進而導致製造成本無法下降。In addition, the reflective surface of the light guiding element of the prior art has only a single curvature in any cross section, and the curvature must be extended upward to a certain height to receive most of the light of the light emitting diode in the corresponding section. The light guiding element must have a corresponding thickness, which in turn leads to a failure in manufacturing cost.
此外,電鍍反射層所形成的反射面為金屬反射面,會吸收部分發光二極體發出的光線,而造成光損失。In addition, the reflecting surface formed by the electroplating reflective layer is a metal reflecting surface, which absorbs light emitted by a part of the light emitting diode and causes light loss.

The light-emitting lens does not need to be plated with a reflective layer as a whole, thereby simplifying the manufacturing process of the light guiding lens and further reducing the manufacturing cost. Moreover, if all the light of the light-emitting element is guided by the first reflecting surface, the light guiding lens is generally thickened as in the prior art so that the first reflecting surface can be fully extended, but the light guiding lens of the present invention is the first reflection. The surface and the reflective structure respectively guide the light of different parts of the light-emitting element, and the first reflective surface does not need to be extended excessively, so that the thickness of the light guide lens of the present invention can be smaller than that of the light guide lens having only the first reflective surface, further reducing the manufacturing. cost. In addition, since it is not necessary to plate the reflective layer, light loss caused by the light of the light-emitting element being absorbed by the reflective layer can be avoided.

The reflective structure 140 includes a plurality of reflective surfaces connected between the second side 112 and the first reflective surface 130.
在本實施例中,第一反射面130是凸拋物面,且底面110的通過入光部113的中心的法線N通過此凸拋物面的焦點F,將發光元件置放於焦點F可使第一反射面130匯聚發光元件所發出的光線,但並不以此為限,第一反射面130也可為具有其他功能的曲面。In this embodiment, the first reflective surface 130 is a convex paraboloid, and the normal N passing through the center of the light incident portion 113 of the bottom surface 110 passes through the focal point F of the convex paraboloid, and the light emitting element is placed at the focus F to make the first The reflective surface 130 converges the light emitted by the light-emitting element, but is not limited thereto. The first reflective surface 130 may also be a curved surface having other functions.
在本實施例中,反射結構140的這些反射面包括第二反射面141、第三反射面142以及第四反射面143。第二反射面141連接於第一反射面130且朝遠離第一反射面130及底面110的方向向上延伸。第三反射面142連接於第二反射面141且朝遠離第二反射面的141方向向下延伸並凸出於第二側邊112。第四反射面143連接於第三反射面142與第二側邊112之間。雖然本實施例的反射結構包括第二反射面141、第三反射面142以及第四反射面143等三個反射面,但並不僅限於此。In the embodiment, the reflective surfaces of the reflective structure 140 include a second reflective surface 141, a third reflective surface 142, and a fourth reflective surface 143. The second reflecting surface 141 is connected to the first reflecting surface 130 and extends upward in a direction away from the first reflecting surface 130 and the bottom surface 110. The third reflecting surface 142 is connected to the second reflecting surface 141 and extends downward in a direction away from the second reflecting surface 141 and protrudes from the second side 112.

Although the reflective structure of the present embodiment includes three reflective surfaces such as the second reflective surface 141, the third reflective surface 142, and the fourth reflective surface 143, it is not limited thereto.
在本實施例中,第二反射面141、第三反射面142及第四反射面143在平行於XZ面(即平行於底面110)的剖面圖中為拋物線,以具有匯聚光線的功能,但並不僅限於此,這些反射面也可為具有其他功能的曲面。In this embodiment, the second reflecting surface 141, the third reflecting surface 142, and the fourth reflecting surface 143 are parabolic in a cross-sectional view parallel to the XZ plane (ie, parallel to the bottom surface 110) to have a function of concentrating light, but Not limited to this, these reflective surfaces can also be curved surfaces with other functions.
入光部113可與發光元件相對配置,且在本實施例中,入光部可為凹部,但並不僅限於此,入光部113也可為凸部或平面,且入光部113在底面110上可具有圓形、正方形或其他多邊形的輪廓。另應注意的是,雖然本實施例僅繪示一個入光部113,然而入光部113可對應發光元件的數量而設置。在本實施例中,入光部113可整體位於第一反射面130往底面110垂直投影的投影區域S內,但並不僅限於此。在其他實施例中,入光部113也可部分地位於反射結構140的下方。The light incident portion 113 can be disposed opposite to the light emitting element. In the embodiment, the light incident portion can be a concave portion, but the light incident portion 113 can also be a convex portion or a flat surface, and the light incident portion 113 can be a bottom surface. The 110 may have a contour of a circle, a square or other polygon. It should be noted that although the embodiment only shows one light incident portion 113, the light incident portion 113 may be disposed corresponding to the number of light emitting elements. In the present embodiment, the light incident portion 113 may be entirely located in the projection region S in which the first reflective surface 130 is vertically projected toward the bottom surface 110, but is not limited thereto. In other embodiments, the light incident portion 113 may also be partially located below the reflective structure 140.
在本實施例中,第一反射面130與底面110的最遠距離d1可大於反射結構140整體與底面110的最遠距離d2。在本實施例中,第一反射面130為主要反射發光元件光線的反射面,且又連接於出光面120,因此可具有大於反射結構140整體的範圍,進而具有較高的高度,但並不僅限於此。在其他實施例中,第一反射面130也可與反射結構140等高或略低於反射結構140。In this embodiment, the farthest distance d1 of the first reflective surface 130 and the bottom surface 110 may be greater than the farthest distance d2 of the entire reflective structure 140 and the bottom surface 110. In this embodiment, the first reflective surface 130 is a reflective surface that mainly reflects the light of the light-emitting element, and is connected to the light-emitting surface 120, and thus may have a larger range than the entire reflective structure 140, and thus has a higher height, but not only Limited to this. In other embodiments, the first reflective surface 130 can also be equal to or slightly lower than the reflective structure 140.
圖2為本創作一實施例的光源模組示意圖。請參照圖2,光源模組10包括發光元件101與上述導光透鏡100。發光元件101可為發光二極體封裝元件,但並不僅限於此,發光元件101也可為其他固態發光元件。發光元件101對應於入光部113且提供第一部分光線L1經由第一反射面130反射而從出光面120出射,在本實施例中,第一反射面130為對應發光元件101的第一部分光線L1的全反射面。發光元件101另提供第二部分光線L2經由反射結構140的多個反射面依序反射而從出光面120出射,在本實施例中,第二部分光線L2依序經由第二反射面141、第三反射面142以及第四反射面143反射後從出光面120出射。FIG. 2 is a schematic diagram of a light source module according to an embodiment of the present invention. Referring to FIG. 2 , the light source module 10 includes a light emitting element 101 and the light guiding lens 100 described above. The light-emitting element 101 may be a light-emitting diode package element, but is not limited thereto, and the light-emitting element 101 may be another solid-state light-emitting element. The light-emitting element 101 corresponds to the light-input portion 113 and provides a first partial light ray L1 to be reflected from the light-emitting surface 120 via the first reflective surface 130. In the embodiment, the first reflective surface 130 is the first partial light ray L1 corresponding to the light-emitting element 101. The total reflection surface. The light-emitting element 101 further provides the second partial light ray L2 to be sequentially reflected from the light-emitting surface 120 via the plurality of reflective surfaces of the reflective structure 140. In this embodiment, the second partial light ray L2 is sequentially passed through the second reflective surface 141, The three reflecting surfaces 142 and the fourth reflecting surface 143 are reflected and emitted from the light emitting surface 120.
在本實施例中,反射結構140的這些反射面皆可設計為全反射面。第四反射面143與第三反射面142之間可具有一個固定的夾角θ。在一實施例中,夾角θ為82~98度,而在一導光透鏡為聚光透鏡的實施例中,夾角θ為90度。發光元件201發出的第二部分光線L2可被第二反射面141全反射後朝向第三反射面142,而被第三反射面142全反射後再朝向第四反射面143,再被第四反射面143全反射後由出光面120出射。In this embodiment, the reflective surfaces of the reflective structure 140 can be designed as a total reflection surface. The fourth reflecting surface 143 and the third reflecting surface 142 may have a fixed angle θ. In one embodiment, the included angle θ is 82 to 98 degrees, and in an embodiment where the light guiding lens is a collecting lens, the included angle θ is 90 degrees. The second partial light ray L2 emitted by the illuminating element 201 can be totally reflected by the second reflecting surface 141 and then directed toward the third reflecting surface 142, and is totally reflected by the third reflecting surface 142 and then directed toward the fourth reflecting surface 143, and then reflected by the fourth reflecting surface 143. The surface 143 is totally reflected and then emitted from the light exit surface 120.
上述的反射結構140可更包括連接在第三反射面142與第四反射面143之間的延伸面144,且此延伸面144平行於底面110。若底面110接收到來自於第三反射面142的第二部分光線L2,這些第二部分光線L2有很大的比例將會穿出底面110而產生漏光,若第三反射面142可整體凸出於底面110的第二側邊112,可有效地減少直接由第三反射面142射往底面110的第二部分光線L2,以減少漏光。然而,受限於導光透鏡100的設計,當第四反射面143與第三反射面142之間保持夾角θ,且第四反射面143又是直接連接於第三反射面142時,第三反射面142往往無法整體凸出於第二側邊112,如圖2的虛線DL所示,第三反射面142沿著底面110的法線垂直投影的投影區域S1涵蓋了第四反射面143以及部分的底面110。藉由本實施例設於第三反射面142與第四反射面143之間的延伸面144,第四反射面143連接於延伸面144的位置較虛線DL靠近出光面120,連帶使得底面110的第二側邊112可較虛線DL往出光面120的方向退縮,而減少與投影區域S1的重疊部分或完全位於投影區域S1之外,以減少在底面110的漏光量。雖然延伸面144也可能因涵蓋於垂直投影S1中而發生漏光,但射往延伸面144的第二部分光線L2的光線量遠少於原本會射往底面110的光線量,因此導光透鏡100整體的漏光量可因具有延伸面144而減少。The reflective structure 140 may further include an extended surface 144 connected between the third reflective surface 142 and the fourth reflective surface 143, and the extended surface 144 is parallel to the bottom surface 110. If the bottom surface 110 receives the second partial light L2 from the third reflecting surface 142, a large proportion of the second partial light rays L2 will pass through the bottom surface 110 to generate light leakage, and if the third reflecting surface 142 can be integrally protruded The second side 112 of the bottom surface 110 can effectively reduce the second partial light L2 directly incident on the bottom surface 110 by the third reflecting surface 142 to reduce light leakage. However, limited by the design of the light guiding lens 100, when the fourth reflecting surface 143 and the third reflecting surface 142 maintain an angle θ, and the fourth reflecting surface 143 is directly connected to the third reflecting surface 142, the third The reflecting surface 142 often cannot protrude integrally from the second side 112. As shown by the broken line DL of FIG. 2, the projection area S1 of the third reflecting surface 142 vertically projected along the normal line of the bottom surface 110 covers the fourth reflecting surface 143 and Part of the bottom surface 110. With the extending surface 144 disposed between the third reflecting surface 142 and the fourth reflecting surface 143 in the embodiment, the fourth reflecting surface 143 is connected to the extending surface 144 at a position closer to the light emitting surface 120 than the broken line DL, so that the bottom surface 110 is The two side edges 112 can be retracted in the direction of the light exit surface 120 from the broken line DL, and the overlapping portion with the projection area S1 is reduced or completely outside the projection area S1 to reduce the amount of light leakage on the bottom surface 110. Although the extended surface 144 may also leak light due to being covered in the vertical projection S1, the amount of light of the second partial light L2 directed to the extended surface 144 is much smaller than the amount of light originally incident on the bottom surface 110, and thus the light guiding lens 100 The overall amount of light leakage can be reduced by having an extended surface 144.

本實施例的導光透鏡100因具有第一反射面130及反射結構140分別導引發光元件101所發出不同部分的光線,因此發光元件101發出的大部分光線在第一反射面130及反射結構140的導引下都可由出光面120出射,且導光透鏡100整體無須電鍍反射層,因而簡化了導光透鏡100的製作流程,進而降低製造成本。又,若以第一反射面130導引發光元件101的所有光線,勢必如習知技術一般將導光透鏡100增厚以使第一反射面130可充分延伸,然而本創作的導光透鏡100是以第一反射面130與反射結構140分別導引發光元件101第一部分光線L1與第二部分光線L2,第一反射面無需過度的延伸,使得本創作的導光透鏡100的厚度可小於僅有第一反射面130的導光透鏡,進一步的降低了製造成本。此外,由於無須電鍍反射層,也可避免發光元件的光線被反射層所吸收而造成的光損失。The light guiding lens 100 of the present embodiment has the first reflecting surface 130 and the reflecting structure 140 respectively guiding different portions of the light emitted by the light emitting element 101, so that most of the light emitted by the light emitting element 101 is on the first reflecting surface 130 and the reflective structure. The guiding of the 140 can be emitted by the light-emitting surface 120, and the light guiding lens 100 does not need to be plated with a reflective layer as a whole, thereby simplifying the manufacturing process of the light guiding lens 100, thereby reducing the manufacturing cost. Moreover, if all the light of the light-emitting element 101 is guided by the first reflecting surface 130, the light guiding lens 100 is generally thickened as in the prior art so that the first reflecting surface 130 can be sufficiently extended. However, the light guiding lens 100 of the present invention is created. The first reflective surface 130 and the reflective structure 140 respectively guide the first partial light L1 and the second partial light L2 of the light emitting element 101, and the first reflective surface does not need to be extended excessively, so that the thickness of the light guiding lens 100 of the present invention can be less than The light guiding lens having the first reflecting surface 130 further reduces the manufacturing cost. In addition, since it is not necessary to plate the reflective layer, light loss caused by the light of the light-emitting element being absorbed by the reflective layer can be avoided.
