More concentrated.
每一側面113自該入光面111朝該出光面112逐漸遠離該光軸L1而延伸，使該導光透鏡11的厚度大致上是由該入光面111朝該出光面112逐漸變厚。更進一步地，本實施例的每一側面113為朝該光軸L1略微弧突的曲面，亦即，每一側面113有局部朝該導光透鏡11內部內凹 。但於實施上，該等側面113也可以未有內凹設計而呈平面。 Each of the side faces 113 extends from the light-incident surface 111 toward the light-emitting surface 112 away from the optical axis L1, and the thickness of the light-guiding lens 11 is gradually increased from the light-incident surface 111 toward the light-emitting surface 112. Further, each side surface 113 of the embodiment is a curved surface slightly curved toward the optical axis L1, that is, each side surface 113 is partially concave toward the inside of the light guiding lens 11. . However, in practice, the sides 113 may also be planar without a concave design.
該發光單元12位於該導光透鏡11的入光面111的一側，並包括一大致呈直立延伸之板片狀的電路板121，以及一安裝在該電路板121上的發光件122。該發光件122的位置對應於該入光面111的該曲面部115。在本實施例中，該發光件122為一發光二極體(LED)，且該發光件122位於該光軸L1與該連接線L2的交界處，此時配合圖未示出的一遮光板或其他遮光控制元件，該車燈可作為一遠燈。 The light emitting unit 12 is located on one side of the light incident surface 111 of the light guiding lens 11 and includes a circuit board 121 having a substantially vertical extending plate shape, and a light emitting member 122 mounted on the circuit board 121. The position of the illuminating member 122 corresponds to the curved surface portion 115 of the light incident surface 111. In this embodiment, the illuminating member 122 is a light emitting diode (LED), and the illuminating member 122 is located at a boundary between the optical axis L1 and the connecting line L2, and a visor not shown in the figure is used. Or other shading control element, the headlight can be used as a remote light.
該散熱件2位於該導光透鏡11的入光面111的一側，並與該電路板121及該導光透鏡11組裝結合。該散熱件2包括一大致平行該電路板121而延伸並供該電路板121安裝的散熱基板21，以及數個自該散熱基板21朝遠離該發光模組1的方向延伸的散熱鰭片22。該散熱件2與該電路板121之間，以及該散熱件2與該導光透鏡11之間，皆可利用螺絲鎖固結合。 The heat sink 2 is located on one side of the light incident surface 111 of the light guiding lens 11 and is assembled and coupled with the circuit board 121 and the light guiding lens 11 . The heat dissipating member 2 includes a heat dissipating substrate 21 extending substantially parallel to the circuit board 121 and mounted on the circuit board 121, and a plurality of heat dissipating fins 22 extending from the heat dissipating substrate 21 in a direction away from the light emitting module 1. The heat dissipating member 2 and the circuit board 121, and between the heat dissipating member 2 and the light guiding lens 11, can be locked by screws.
參閱圖2~4，本發明使用時，該發光件122發出的光線經由該入光面111進入該導光透鏡11內部，且部分光線(如圖4箭頭A)經由該導光透鏡11傳導，直接朝前射向該出光面112而射出，此部分光線主要集中照明車燈前方的中央範圍。部分光線於該導光透鏡11內部受到該等側面113多次反射而傳導前進(如圖4箭頭B)，再朝該出光面112射出，此部分的光線可受到橫向傳導，此乃因為該導光 透鏡11由該入光面111朝該出光面112漸厚的設計，使光線持續受到該等側面113反射時，當光線愈往前接近該出光面112時，入射到側面113的入射角愈大，則出射光線愈能往左右兩側射出以補償左右兩側區域之亮度，因此有助於引導光線橫向延伸照射。 Referring to FIGS. 2 to 4, when the present invention is used, light emitted by the illuminating member 122 enters the inside of the light guiding lens 11 via the light incident surface 111, and part of the light (such as arrow A in FIG. 4) is conducted through the light guiding lens 11. The light is directly emitted toward the light exiting surface 112, and the light is mainly concentrated in the central range in front of the illumination lamp. Part of the light is reflected by the side surfaces 113 multiple times in the interior of the light guiding lens 11 to conduct (for example, arrow B in FIG. 4), and then emitted toward the light emitting surface 112, and the light of the portion can be laterally transmitted, because the guide light is guided. Light The lens 11 is designed to be thicker toward the light-emitting surface 112 by the light-incident surface 111. When the light is continuously reflected by the side surfaces 113, the incident angle of the incident surface 113 is greater as the light approaches the light-emitting surface 112. The more the outgoing light can be emitted to the left and right sides to compensate for the brightness of the left and right sides, thus helping to guide the light to extend laterally.
故本發明的結構設計，其導引光線原理為產生直向光線與橫向光線，此兩部分光線配合下，讓整體射出光線由中央往左右兩側皆為均勻，可避免照射平面上有局部較暗之暗帶區域產生，因此本發明可提供高亮度且均勻的照明，再搭配該出光面112的形狀可控制光型，以產生符合法規之照度要求、照射範圍等規範的光線。而該等側面113之略微向內弧凹的設計，也有助於使光線均勻化，避免局部暗帶產生。此外，本發明的入光面111的曲面部115結構，搭配該發光件122的設置位置，此結構所產生的光線有助於提升明暗截止線處的亮區光線亮度。 Therefore, the structure design of the invention has the principle of guiding light to generate straight rays and lateral rays. The two parts of the light are combined to make the whole emitted light uniform from the center to the left and right sides, so as to avoid local comparison on the illumination plane. The dark dark band region is generated, so the present invention can provide high-brightness and uniform illumination, and the shape of the light-emitting surface 112 can be used to control the light pattern to generate light that meets the specifications of the illumination requirements, illumination range, and the like. The slightly inwardly curved design of the sides 113 also helps to homogenize the light and avoid local dark bands. In addition, the curved surface portion 115 of the light incident surface 111 of the present invention is configured to match the position of the light emitting member 122, and the light generated by the structure helps to increase the brightness of the bright region light at the cut-off line.
綜上所述，藉由該導光透鏡11的入光面111與出光面112的結構，搭配該發光件122的設置位置，使本發明的光利用效率與光型控制佳，能產生高亮度且均勻的照明光線，得到更佳的光學效果，對於車輛照明應用有極大的助益。 As described above, by adopting the configuration of the light incident surface 111 and the light exit surface 112 of the light guiding lens 11 and the arrangement position of the light emitting member 122, the light use efficiency and the light type control of the present invention are excellent, and high brightness can be generated. Uniform illumination and better optical performance are of great help for vehicle lighting applications.
參閱圖5，本發明車燈之一第二實施例，與該第一實施例不同的地方在於：本實施例的發光件122具有一底緣123，該底緣123位於該光軸L1上。本實施例藉由改變該發光件122的位置，此時配合圖未示出的一遮光板或 其他遮光控制元件，該車燈可作為一近燈。 Referring to Fig. 5, a second embodiment of the lamp of the present invention differs from the first embodiment in that the illuminating member 122 of the present embodiment has a bottom edge 123 which is located on the optical axis L1. In this embodiment, by changing the position of the illuminating member 122, a visor not shown in the figure or Other shading control elements, the headlights can be used as a close light.
由本實施例與該第一實施例可知，本發明的發光件122只要是鄰近該光軸L1與該連接線L2的交界處設置即可，但不需限定該發光件122的具體位置，因為只要微調該發光件122位置，就可以因應不同車燈種類需求來提供不同的照射角度與光型。 It can be seen from the present embodiment and the first embodiment that the illuminating member 122 of the present invention is only required to be disposed adjacent to the boundary between the optical axis L1 and the connecting line L2, but the specific position of the illuminating member 122 is not limited, as long as By fine-tuning the position of the illuminating member 122, different illumination angles and light patterns can be provided in response to different types of lamp types.
參閱圖6，本發明車燈之一第三實施例，與該第一實施例不同的地方在於：本實施例的導光透鏡11的該出光面112是由與該等側面113連接的部位往中央逐漸朝該入光面111弧突，類似於凹透鏡的結構，使射出光線相對於該第一實施例可更為往左右兩側擴散，藉此提升出射光線之左右兩側的照射角度，使照射範圍廣。 Referring to FIG. 6, a third embodiment of the vehicle lamp of the present invention is different from the first embodiment in that the light-emitting surface 112 of the light guiding lens 11 of the present embodiment is connected to the side surface 113. The center gradually diverge toward the light incident surface 111, similar to the structure of the concave lens, so that the emitted light can be diffused to the left and right sides relative to the first embodiment, thereby increasing the illumination angle of the left and right sides of the outgoing light, so that the illumination angle of the left and right sides of the outgoing light is increased. Wide range of illumination.
參閱圖7，本發明車燈之一第四實施例，與該第一實施例不同的地方在於：本實施例包括數個發光模組1，該等發光模組1設置於單一的散熱件2上，且該等發光模組1可以共用一電路板121。 Referring to FIG. 7 , a fourth embodiment of the vehicle lamp of the present invention is different from the first embodiment in that: the embodiment includes a plurality of light-emitting modules 1 , and the light-emitting modules 1 are disposed on a single heat-dissipating component 2 . The light-emitting modules 1 can share a circuit board 121.
惟以上所述者，僅為本發明之實施例而已，當不能以此限定本發明實施之範圍，即大凡依本發明申請專利範圍及專利說明書內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。 However, the above is only the embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and the patent specification of the present invention are still It is within the scope of the patent of the present invention.
