This application claims priority from Chinese Patent Application No. 202010519122.7, filed on June 9, 2020, the contents of which are incorporated herein by reference.

車両用前照灯の照明装置において、マトリクス(Matrix)型前照灯の照明装置は、ハイビーム照明領域を複数の照明領域に細分化することで、アダプティブハイビームの機能を実現し、車両前方の対象に対して遮蔽を行うことによって、他の道路利用者を眩惑させることを避け、したがって運転安全を向上させる。 Among vehicle headlight lighting systems, matrix-type headlight lighting systems subdivide the high beam lighting area into multiple lighting areas to realize the adaptive high beam function and illuminate objects in front of the vehicle. By providing a shield against the road, it avoids dazzling other road users and thus improves driving safety.

マトリクス(Matrix)型前照灯の照明装置における1次光学素子(例えば、リフレクタ、集光素子)は、マトリクス(Matrix)型前照灯の照明装置のコア部品である。この1次光学素子により光源からの出射光を精確にガイドし、中間的光の分布を形成し、そして2次光学素子(例えばレンズ)によってさらに調整し、所望の配光パターンを得る。そのため、1次光学素子および2次光学素子の製造精度および組み立て精度に対する要求が非常に高い。従来のマトリクス(Matrix)型前照灯の照明装置における各部品が下記のように取付、接続される。支持板がねじによって、回路基板が設置された放熱装置に固着され、1次光学素子が支持板に固定され、1次光学素子を位置制限するために押さえ板が、1次光学素子の上方に覆うように設置されるとともに支持板にねじによって固着され、2次光学素子がレンズホルダーの先端部に取り付けられ、レンズホルダーの後端部が放熱装置に固着される。部品数が多いため、1次光学素子と、2次光学素子と、レンズホルダーとの相対位置の精度は、支持板と押さえ板との間、支持板と放熱装置との間およびレンズホルダーと放熱装置との間の複数回の位置合わせ、取り付け、接続による影響を受けており、つまり、三者間の複数回の組み立てによる誤差で、各光学素子間の相対位置の精度が十分高くない。 A primary optical element (eg, a reflector, a condensing element) in a Matrix headlamp illumination device is a core component of the Matrix headlamp illumination device. The primary optical element precisely guides the light emitted from the light source to form an intermediate light distribution, which is further adjusted by the secondary optical element (for example, a lens) to obtain a desired light distribution pattern. Therefore, there are very high demands on the manufacturing accuracy and assembly accuracy of the primary optical element and the secondary optical element. Each component in a conventional matrix type headlamp lighting device is attached and connected as follows. A support plate is fixed to the heat dissipation device on which the circuit board is installed by screws, a primary optical element is fixed to the support plate, and a holding plate is placed above the primary optical element to limit the position of the primary optical element. The secondary optical element is attached to the tip of the lens holder, and the rear end of the lens holder is fixed to the heat dissipation device. Due to the large number of parts, the relative positional accuracy of the primary optical element, secondary optical element, and lens holder is limited by the accuracy of the relative positions between the support plate and the holding plate, between the support plate and the heat dissipation device, and between the lens holder and the heat dissipation device. The accuracy of the relative position between each optical element is not high enough due to the influence of multiple alignments, attachments, and connections with the device, that is, errors due to multiple assembly between the three parties.

図1~図6に示すように、本発明に係る前照灯光学部品は、集光素子1とレンズホルダー2とを備え、前記レンズホルダー2に、前記集光素子1を収容するためのキャビティが形成され、このキャビティ内および前記集光素子1に、互いに嵌合するための嵌合構造が形成され、前記集光素子1が、前記嵌合構造によって前記キャビティ内に嵌合される。 As shown in FIGS. 1 to 6, the headlamp optical component according to the present invention includes a condensing element 1 and a lens holder 2, and the lens holder 2 has a cavity for accommodating the condensing element 1. A fitting structure for fitting each other is formed in this cavity and on the light condensing element 1, and the light condensing element 1 is fitted into the cavity by the fitting structure.

従来の前照灯光学部品において、集光素子1とレンズホルダー2は、前照灯光学部品を構成するための重要な構造であり、両者間が間接に位置合わさるため、複数回の位置合わせによる取付誤差が生じてしまう。そして、集光素子1とレンズホルダー2との間の取付精度が、前照灯の投光効果に直接影響を及ぼし、これに対して、本発明に係る集光素子1およびレンズホルダー2に、互いに嵌合するための嵌合構造が形成されることで、集光素子1とレンズホルダー2が直接接続して位置合わさる。したがって、位置合わせによる取付誤差が減少し、両者間の取付精度が向上する。 In conventional headlight optical components, the condensing element 1 and lens holder 2 are important structures for configuring the headlight optical component, and because they are indirectly aligned, it is difficult to align them multiple times. Installation errors will occur. The mounting accuracy between the condensing element 1 and the lens holder 2 directly affects the light projection effect of the headlamp, and on the other hand, the condensing element 1 and the lens holder 2 according to the present invention have By forming a fitting structure for fitting each other, the condensing element 1 and the lens holder 2 are directly connected and aligned. Therefore, mounting errors due to positioning are reduced, and mounting accuracy between the two is improved.

本発明に係る集光素子1とレンズホルダー2との嵌合について、2種の構成を挙げる。その1種の態様として、集光素子1とレンズホルダー2とが一体成形品として形成されることが好ましい。このような嵌合構造により、集光素子1とレンズホルダー2との位置合わせの精度がより高い。 Regarding the fitting between the condensing element 1 and the lens holder 2 according to the present invention, two types of configurations are mentioned. In one embodiment, the condensing element 1 and the lens holder 2 are preferably formed as an integrally molded product. With such a fitting structure, the accuracy of alignment between the condensing element 1 and the lens holder 2 is higher.

なお、集光素子1とレンズホルダー2は一体成形品であるため、集光素子1とレンズホルダー2は、互いに同種の材料からなってもよく、互いに異種の材料からなってもよい。好ましくは、集光素子1とレンズホルダー2は、互いに異種の材料からなる。集光素子1は、耐熱性、光学的性能に比較的優れた材料(例えば、シリコンゴム)を用いて成形してもよい。レンズホルダー2は、集光素子1をより良好に支持し、その安定性を高めるように、剛性に比較的優れた材料(例えば、PC、PMMAなどまたはこれらの混合物)を用いて成形してもよい。 Note that since the condensing element 1 and the lens holder 2 are integrally molded, the condensing element 1 and the lens holder 2 may be made of the same kind of material or may be made of different kinds of materials. Preferably, the condensing element 1 and the lens holder 2 are made of different materials. The condensing element 1 may be molded using a material (for example, silicone rubber) that has relatively excellent heat resistance and optical performance. The lens holder 2 may be molded using a material with relatively high rigidity (for example, PC, PMMA, etc., or a mixture thereof) so as to better support the condensing element 1 and increase its stability. good.

そして、レンズホルダー2と集光素子1をインサート成形により一体成形し、その成形プロセスは、図4、図6に示すように、まず、レンズホルダー2を射出成形する。次いで、レンズホルダー2を、集光素子1を射出するための金型内に配置する。次いで、材料を注入することでレンズホルダー2と集光素子1との一体成形品を得ることができる。もちろん、レンズホルダー2と集光素子1との一体構造を実現できる他の成形のプロセスや方法を採用してもよく、例えば、二色射出成形を採用してもよい。 Then, the lens holder 2 and the condensing element 1 are integrally molded by insert molding, and in the molding process, as shown in FIGS. 4 and 6, first, the lens holder 2 is injection molded. Next, the lens holder 2 is placed in a mold for ejecting the condensing element 1. Next, by injecting the material, an integrally molded product of the lens holder 2 and the condensing element 1 can be obtained. Of course, other molding processes and methods that can realize an integral structure of the lens holder 2 and the condensing element 1 may be employed, for example, two-color injection molding may be employed.

図7と図8に示すように、本発明の好ましい一実施形態として、前記嵌合構造は、前記キャビティの内周壁に設けられた嵌入部201および前記集光素子1の先端部に設けられた嵌合溝1014を含む。そして、該嵌合溝1014は、前記集光素子1の出光部の四周に一体形成されている。したがって、嵌合構造を集光素子1の先端部に構成することにより、出光部1013の剛性を効果的に向上させることができる。 As shown in FIGS. 7 and 8, in a preferred embodiment of the present invention, the fitting structure is provided in a fitting portion 201 provided on the inner circumferential wall of the cavity and a tip portion of the light condensing element 1. A fitting groove 1014 is included. The fitting groove 1014 is integrally formed around the light emitting portion of the light condensing element 1 . Therefore, by configuring the fitting structure at the tip of the light condensing element 1, the rigidity of the light emitting section 1013 can be effectively improved.

図7に示すように、レンズホルダー2には、集光素子1を収容するためのキャビティが形成されている。該キャビティは、前後に貫通しており、その四周の内周壁に嵌入部201が形成されている。嵌入部201は、四周から中心へ延在しており、前記キャビティの内周壁に沿って全周にわたって形成された薄板状のものである。前記嵌入部201には、前記嵌入部201を貫通する複数の貫通孔2011が形成されている。 As shown in FIG. 7, a cavity for accommodating the condensing element 1 is formed in the lens holder 2. The cavity penetrates from front to back, and fitting portions 201 are formed on the inner circumferential walls of the four peripheries. The fitting portion 201 extends from the four peripheries to the center, and is formed in a thin plate shape along the entire circumference along the inner peripheral wall of the cavity. A plurality of through holes 2011 are formed in the fitting portion 201 .

図8に示すように、前記嵌合溝1014は、前記嵌入部201を嵌め込ませる溝であり、この嵌合溝1014の内部に、一対一で前記貫通孔2011に嵌め込むことができる柱体1015が一体形成されている。 As shown in FIG. 8, the fitting groove 1014 is a groove into which the fitting part 201 is fitted, and inside the fitting groove 1014, a column 1015 that can be fitted one-on-one into the through hole 2011 is provided. are integrally formed.

そして、前記嵌合溝1014は、前記集光素子1の出光部の四周に一体形成されている。 The fitting groove 1014 is integrally formed around the light emitting portion of the light condensing element 1 .

したがって、本発明に係る嵌合構造は、嵌入部201を嵌合溝1014内に嵌合させるとともに、嵌合構造をより強固にし嵌合強度を高めるために、柱体1015を貫通孔2011に嵌合させることで、集光素子1とレンズホルダー2とを一体に強固に嵌合させることができる。また、集光素子1とレンズホルダー2とが一体に強固に嵌合すると、両者は分離不能になり、図7および図8で二つの部品を別々で示すことは、両者の具体的な構造を示すためである。 Therefore, the fitting structure according to the present invention fits the fitting part 201 into the fitting groove 1014, and also fits the column 1015 into the through hole 2011 in order to make the fitting structure stronger and increase the fitting strength. By matching them together, the condensing element 1 and the lens holder 2 can be firmly fitted together. Furthermore, when the condensing element 1 and the lens holder 2 are firmly fitted together, they cannot be separated, and the fact that the two parts are shown separately in FIGS. This is to show.

集光素子1とレンズホルダー2との嵌合の他の構成として、レンズホルダー2は、別体構造(互いに別体の部材により構成される構造)であり、上下で分割されたものであってもよく、左右で分割されたものであってもよい。この場合、嵌入部201における貫通孔2011の代わりに、開口を有する係合溝が設けられており、該係合溝が柱体1015に係合可能である。該構造によれば、集光素子1とレンズホルダー2との取り付け精度を確保するとともに、取付を容易にすることができる。取り付けるとき、レンズホルダー2の互いに別体の部材を組み立てることにより係合孔と柱体1015とを係合させて集光素子1をレンズホルダー2に嵌合させる。取り外すとき、別体構造のレンズホルダー2を分離させれば、集光素子1をレンズホルダー2から分離させることができる。 Another configuration of the fitting between the condensing element 1 and the lens holder 2 is that the lens holder 2 has a separate structure (a structure composed of mutually separate members) and is divided into upper and lower parts. It may also be divided into left and right parts. In this case, an engagement groove having an opening is provided in place of the through hole 2011 in the fitting portion 201, and the engagement groove can engage with the columnar body 1015. According to this structure, it is possible to ensure the accuracy of mounting the condensing element 1 and the lens holder 2, and to facilitate the mounting. When attaching, by assembling the mutually separate members of the lens holder 2, the engagement hole and the column 1015 are engaged, and the condensing element 1 is fitted into the lens holder 2. When removing the lens holder 2, the condensing element 1 can be separated from the lens holder 2 by separating the lens holder 2, which has a separate structure.

図8に示すように、本発明の他の好ましい一実施形態として、前記集光素子1は、複数のコリメートユニット101を含む。各前記コリメートユニット101は、それぞれ入光部1011と、導光部1012と、出光部1013とを含む。各前記出光部1013は合わせて前記集光素子1の出光部として一体形成され、各前記導光部1012の間に、開口が出光方向に沿って漸次に小さくなるくさび状隙間102が形成されている。なお、各前記導光部1012の縦方向断面積は、前から後ろへ漸次に小さくなる。 As shown in FIG. 8, in another preferred embodiment of the present invention, the light condensing element 1 includes a plurality of collimating units 101. Each of the collimating units 101 includes a light input section 1011, a light guide section 1012, and a light output section 1013. Each of the light emitting parts 1013 is integrally formed as a light emitting part of the light condensing element 1, and a wedge-shaped gap 102 is formed between each of the light guide parts 1012, the opening of which gradually becomes smaller along the light emitting direction. There is. Note that the longitudinal cross-sectional area of each of the light guide portions 1012 gradually decreases from the front to the back.

コリメートユニット101は、入射光線を集光してコリメートするものである。各コリメートユニット101は、それぞれ入光部1011と、導光部1012と、出光部1013とを備え、入光部1011と導光部1012とが一対一で対応しており、かつ、すべての出光部1013が互いに接続されて集光素子1の出光部を構成する。つまり、集光素子1は、複数の入光部1011と複数の導光部1012を有するが、これらの入光部1011および導光部1012が同一の出光部を共用する。そして、該集光素子1の出光部は、レンズホルダー2のキャビティ内に一体成形される。該集光素子1の出光部とレンズホルダー2とを一体成形することにより、出光部の位置の安定性を確保できる。これは、該集光素子1の出光部が、配光パターンに影響を与える重要な光学面であり、取り付けるときや使用中に、熱や力によって変形して配光パターンに影響を及ぼすおそれがあるため、レンズホルダー2と一体成形することにより、集光素子1の出光部の変形を抑えまたは避けることができ、光の出射がより安定であるからである。 The collimating unit 101 collects and collimates the incident light beam. Each collimating unit 101 includes a light input section 1011, a light guide section 1012, and a light output section 1013, and the light input section 1011 and the light guide section 1012 correspond one-to-one, and The portions 1013 are connected to each other to constitute a light output portion of the light condensing element 1. That is, although the light condensing element 1 has a plurality of light entrance parts 1011 and a plurality of light guide parts 1012, these light entrance parts 1011 and light guide parts 1012 share the same light output part. The light output portion of the light condensing element 1 is integrally molded within the cavity of the lens holder 2. By integrally molding the light emitting part of the light condensing element 1 and the lens holder 2, the stability of the position of the light emitting part can be ensured. This is because the light emitting part of the light condensing element 1 is an important optical surface that affects the light distribution pattern, and there is a risk that it may be deformed by heat or force during installation or use and affect the light distribution pattern. Therefore, by integrally molding the lens holder 2 with the lens holder 2, deformation of the light emitting part of the light condensing element 1 can be suppressed or avoided, and the light emission becomes more stable.

より好ましくは、前記レンズホルダー2は、縦方向断面積が前から後ろへ小さくなってから大きくなるように構成され、前記嵌入部201が、該縦方向断面積が最小の箇所に設けられる。 More preferably, the lens holder 2 is configured such that the vertical cross-sectional area becomes smaller from the front to the back and then increases, and the fitting portion 201 is provided at a location where the vertical cross-sectional area is the smallest.

レンズホルダー2の縦方向断面積を、前から後ろへ小さくなってから大きくなる形状にし、集光素子1の出光部を断面積が最小の箇所に位置させることで、レンズホルダー2の占めるスペースを小さくし、したがって放熱装置7を設置するスペースをより大きく用意することができる。従来技術の、断面積が先端から後端へ漸次に大きくなるレンズホルダー2に対して、本発明に係るレンズホルダー2によれば、関連部品を接続してなした構造をよりコンパクトにすることができる。 The space occupied by the lens holder 2 can be reduced by making the vertical cross-sectional area of the lens holder 2 smaller from front to back and then larger, and by locating the light output part of the condensing element 1 where the cross-sectional area is the smallest. Therefore, a larger space for installing the heat dissipation device 7 can be prepared. In contrast to the conventional lens holder 2 whose cross-sectional area gradually increases from the front end to the rear end, the lens holder 2 according to the present invention allows the structure formed by connecting related parts to be made more compact. can.

本発明の他の好ましい一実施形態として、前記レンズホルダー2に取付部202が設けられ、該取付部202が前記レンズホルダー2の中部領域に設けられる。 In another preferred embodiment of the present invention, the lens holder 2 is provided with a mounting part 202, and the mounting part 202 is provided in the middle region of the lens holder 2.

さらに好ましくは、前記レンズホルダー2の上部に、少なくとも1つの前記取付部202が設けられ、前記レンズホルダー2の下部に、少なくとも2つの前記取付部202が設けられる。このようにして、3つの取付部202により一平面において三角形の取付構造を形成することができるため、レンズホルダー2と放熱装置7との取り付けがより強固である。 More preferably, at least one mounting part 202 is provided at the top of the lens holder 2, and at least two mounting parts 202 are provided at the bottom of the lens holder 2. In this way, a triangular mounting structure can be formed in one plane by the three mounting portions 202, so that the lens holder 2 and the heat dissipation device 7 can be mounted more firmly.

なお、図17に示すように、レンズホルダー2の中部に放熱装置7と固定接続される取付部202が設置されることにより、取付部202が前照灯光学部品とレンズとからなる構造の重心位置により近いため、照明装置の振動安定性が大幅に向上する。該中部は、レンズホルダー2の前後長さの中部領域に位置し、すなわち、レンズホルダー2の、中点から前に1/4長さの位置から、中点から後に1/4長さの位置までの領域内に位置する。 As shown in FIG. 17, by installing the mounting part 202 that is fixedly connected to the heat dissipation device 7 in the middle part of the lens holder 2, the mounting part 202 becomes the center of gravity of the structure consisting of the headlight optical components and the lens. Being closer to the location greatly improves the vibration stability of the lighting device. The middle part is located in the middle region of the front-to-back length of the lens holder 2, that is, from a position of 1/4 length in front of the midpoint of the lens holder 2 to a position of 1/4 length in the back from the midpoint of the lens holder 2. Located within the area of

さらに、前記取付部202は、前方に開口した凹溝構造として形成され、該凹溝構造の内部に、後方に開口した取付用貫通孔または止まり孔が形成された円柱または円形台が設けられ、前記円柱または円形台が前記凹溝構造を貫通するように構成される。凹溝構造によれば、取付部202の厚みをなるべく増やさずに強度を効果的に高めることができる。そして、凹溝構造の内部に円柱または円形台が設けられることで、レンズホルダー2と放熱装置7との取り付け強度を向上させることができるとともに、取付部202と放熱装置7との間の隙間が許容差はずれであっても、加工により調整することができ、円柱または円形台の後端面を調整すればよく、調整量が少ない。もちろん、凹溝構造の内部の設計については、円柱または円形台に限らず、直方体などの他の構造であってもよく、他の構造であっても、放熱装置7の取付部202への取り付けに影響を及ぼすことがない。 Furthermore, the mounting portion 202 is formed as a groove structure that opens at the front, and a cylinder or a circular base is provided inside the groove structure in which a through hole or a blind hole for mounting that opens at the rear is formed; The cylinder or circular pedestal is configured to pass through the groove structure. According to the groove structure, the strength of the mounting portion 202 can be effectively increased without increasing the thickness of the mounting portion 202 as much as possible. By providing a cylinder or a circular stand inside the groove structure, the attachment strength between the lens holder 2 and the heat dissipation device 7 can be improved, and the gap between the mounting portion 202 and the heat dissipation device 7 can be reduced. Even if the tolerance is off, it can be adjusted by machining, and the amount of adjustment is small, as it is sufficient to adjust the rear end surface of the cylinder or circular table. Of course, the internal design of the groove structure is not limited to a cylinder or a circular table, but may be other structures such as a rectangular parallelepiped. It has no effect on

また、本発明の第2の局面は照明装置をさらに提供する。該照明装置は、前から後ろへ順に、2次光学素子3と、上記の技術案のいずれか1種による前照灯光学部品と、前記前照灯光学部品の後端部を位置決めするための位置決め部材4と、光源5と、前記光源5と電気的に接続する回路基板6と、放熱装置7とを備え、前記2次光学素子3が前記前照灯光学部品の先端部と接続され、前記前照灯光学部品、前記位置決め部材4および前記回路基板6が放熱装置7に固定接続される。 Moreover, the second aspect of the present invention further provides a lighting device. The illumination device includes, from the front to the back, a secondary optical element 3, a headlamp optical component according to one of the above technical schemes, and a device for positioning the rear end of the headlamp optical component. comprising a positioning member 4, a light source 5, a circuit board 6 electrically connected to the light source 5, and a heat dissipation device 7, wherein the secondary optical element 3 is connected to the tip of the headlamp optical component, The headlamp optical component, the positioning member 4 and the circuit board 6 are fixedly connected to a heat dissipation device 7.

ここで、本発明に係る2次光学素子3は、レンズであることが好ましい。該レンズは、レンズホルダー2の先端部に接続され、その接続方式が、レーザ溶接、接着または係合などを採用してもよく、他の適宜な接続方式を採用してもよい。 Here, it is preferable that the secondary optical element 3 according to the present invention is a lens. The lens is connected to the tip of the lens holder 2, and the connection method may be laser welding, adhesion, engagement, or any other suitable connection method.

図15に示すように、本発明の具体的な一態様として、前記位置決め部材4に、複数の離隔リブ402が設けられている。隣接する2つの前記離隔リブ402の間に、前記光源5と一対一で対応する位置決め口401が形成されている。 As shown in FIG. 15, as a specific embodiment of the present invention, the positioning member 4 is provided with a plurality of spacing ribs 402. A positioning opening 401 that corresponds one-to-one with the light source 5 is formed between two adjacent separation ribs 402 .

上記の技術案において、集光素子1の複数のコリメートユニット101の間に、くさび状隙間102が形成されている。複数のコリメートユニット101の入光部1011と回路基板6に配置される光源5との相対位置の精度を確保するために、本発明に係る照明装置において、各入光部1011を位置決めするための位置決め部材4が設置される。該位置決め部材4内に、いくつかの離隔リブ402が設けられており、隣接する2つの離隔リブ402の間に、コリメートユニット101を通すとともに位置決めする位置決め口401が形成されている。位置決め口401は、回路基板6に設置される光源5と一対一で対応する。複数のコリメートユニット101は、1列に配置されてもよく、複数列に配置されてもよく、これに対応して、位置決め口401も1列または複数列に配置される。各コリメートユニット101の入光部1011は、対応する位置決め口401に挿入されることで位置決めされる。これによって、集光素子1の出光部1013および入光部1011がともに位置決めされる。集光素子1は、先端が2次光学素子3に対して直接位置決めされ、後端が位置決め部材4によって光源5に対して位置決めされるため、集光素子1の位置決めの精度を効果的に向上させ、出光効果を改善することができる。 In the above technical proposal, a wedge-shaped gap 102 is formed between the plurality of collimating units 101 of the condensing element 1 . In order to ensure the accuracy of the relative position between the light entrance parts 1011 of the plurality of collimating units 101 and the light source 5 arranged on the circuit board 6, in the illumination device according to the present invention, there is a method for positioning each light entrance part 1011. A positioning member 4 is installed. A number of spacing ribs 402 are provided within the positioning member 4, and a positioning opening 401 through which the collimating unit 101 is passed and positioned is formed between two adjacent spacing ribs 402. The positioning opening 401 corresponds one-to-one with the light source 5 installed on the circuit board 6. The plurality of collimating units 101 may be arranged in one row or in multiple rows, and correspondingly, the positioning holes 401 are also arranged in one row or multiple rows. The light entrance part 1011 of each collimating unit 101 is positioned by being inserted into the corresponding positioning opening 401. As a result, both the light output section 1013 and the light input section 1011 of the light condensing element 1 are positioned. Since the tip of the light condensing element 1 is directly positioned with respect to the secondary optical element 3, and the rear end is positioned with respect to the light source 5 by the positioning member 4, the accuracy of positioning of the light condensing element 1 is effectively improved. It is possible to improve the light output effect.

具体的に、図9~図12に示すように、離隔リブ402が離隔板状であり、位置決め口401の横断面の幅が前から後ろへ漸次に狭くなり、コリメートユニット101の横断面の幅も前から後ろへ漸次に狭くなり、但し、位置決め口401の狭くなる変化度合いがコリメートユニット101の狭くなる変化度合いよりも大きく、このようにすれば、コリメートユニット101と離隔リブ402との接触面積をなるべく小さくすることができる。一方、挿入時の案内に寄与でき、他方、接触面積が小さければ位置決めの精度を確保することができる。したがって、さらに具体的に、コリメートユニット101と離隔リブ402との接触は線接触である。同じ理由で、離隔リブ402は円柱体であってもよい。すなわち、離隔リブ402は、矩形または円形の断面形状を有するものであり、コリメートユニット101と線接触する。 Specifically, as shown in FIGS. 9 to 12, the separation rib 402 is in the form of a separation plate, and the width of the cross section of the positioning opening 401 gradually narrows from the front to the back, and the width of the cross section of the collimating unit 101 becomes smaller. However, the degree of narrowing of the positioning port 401 is larger than the degree of narrowing of the collimating unit 101, and by doing this, the contact area between the collimating unit 101 and the separation rib 402 can be reduced. can be made as small as possible. On the one hand, it can contribute to guidance during insertion, and on the other hand, if the contact area is small, positioning accuracy can be ensured. Therefore, more specifically, the contact between the collimating unit 101 and the spacing rib 402 is a line contact. For the same reason, the spacing ribs 402 may be cylindrical. That is, the separation rib 402 has a rectangular or circular cross-sectional shape, and is in line contact with the collimating unit 101.

図13と図14に示すように、位置決め部材4の取付構造は、2つのねじ8によって回路基板6とともに放熱装置7に固定接続される。 As shown in FIGS. 13 and 14, the mounting structure of the positioning member 4 is fixedly connected to the heat dissipation device 7 together with the circuit board 6 by two screws 8.

本発明の他の具体的な態様として、前記取付部202の後端面と前記放熱装置7との間に隙間が設けられている。 As another specific aspect of the present invention, a gap is provided between the rear end surface of the mounting portion 202 and the heat radiating device 7.

図18に示すように、取付部202と放熱装置7とが締付部品(例えばねじ、ボルトなど)によって固定接続される。該締付部品が締め付けられると、レンズホルダー2の後端面が回路基板6に密着するようにレンズホルダー2が付勢され、集光素子1と光源5との相対位置の確実性を確保することができる。そして、レンズホルダー2と放熱装置7との前後方向のオーバーポジショニングを防止するために、取付部202と放熱装置7との間に隙間が設けられ、これによって、製造誤差に起因するレンズホルダー2と放熱装置7の取付の不具合を避ける。 As shown in FIG. 18, the mounting portion 202 and the heat radiating device 7 are fixedly connected by fastening parts (for example, screws, bolts, etc.). When the tightening parts are tightened, the lens holder 2 is biased so that the rear end surface of the lens holder 2 comes into close contact with the circuit board 6, and the relative position between the condensing element 1 and the light source 5 is ensured. I can do it. In order to prevent overpositioning of the lens holder 2 and the heat dissipation device 7 in the front-rear direction, a gap is provided between the mounting portion 202 and the heat dissipation device 7, which prevents the lens holder 2 and the heat dissipation device 7 from being overpositioned due to manufacturing errors. To avoid problems when installing the heat dissipation device 7.

本発明の他の具体的な態様として、前記レンズホルダー2の後端部にフランジ203が形成され、該フランジ203の後側面が前記回路基板6に密着できるように構成される。 As another specific aspect of the present invention, a flange 203 is formed at the rear end of the lens holder 2, and the rear surface of the flange 203 is configured to be in close contact with the circuit board 6.

前記具体的な態様の好ましい態様として、前記レンズホルダー2の後端部にフランジ203が形成され、該フランジ203の後側面にボスが形成され、該ボスの端面が前記回路基板6に密着できるように構成される。 As a preferable embodiment of the specific embodiment, a flange 203 is formed at the rear end of the lens holder 2, and a boss is formed on the rear side of the flange 203, so that the end face of the boss can be brought into close contact with the circuit board 6. It is composed of
