Description
本發明是有關於一種透鏡，特別是指一種應用於車燈，且其中填充有液體介質的液態透鏡。The present invention relates to a lens, and more particularly to a liquid lens applied to a vehicle lamp and filled with a liquid medium.
已知的一種車燈，包含一外殼、至少一安裝在該外殼中的發光元件，以及一位於該發光元件前側的透鏡，該透鏡能將該發光元件的光線導引成適當光形，並且聚光後再投射出。該透鏡為一凸透鏡，通常採用玻璃或塑膠材質製成。但玻璃透鏡的重量較重，當車燈振動時，容易導致車燈中用於固定該玻璃透鏡的一固定框架發生損裂。另一方面，由於凸透鏡整體的厚度並非均勻，凸透鏡上厚度最大處相對厚度最小處，有一定程度的厚度差，而採用塑膠材質製成透鏡雖然具有輕量優點，但是於實務上發現，以塑膠射出成型透鏡時，於透鏡的最大厚度處之局部厚度縮水問題非常明顯，因此塑膠透鏡的成型精度不佳、品質不良，會影響光學效果。此外，以塑膠成型此種凸透鏡型態之透鏡，其成型時間高達30~40分鐘、成型不良率高，透鏡內易生氣泡及霧狀。所以已知的透鏡仍有待改良。A known vehicle lamp includes a housing, at least one light-emitting element mounted in the housing, and a lens located on the front side of the light-emitting element. The lens can guide the light of the light-emitting element into an appropriate light shape and concentrate the light. After the light is projected. The lens is a convex lens, usually made of glass or plastic material. However, the weight of the glass lens is relatively heavy, and when a vehicle lamp vibrates, a fixing frame for fixing the glass lens in the vehicle lamp is easily damaged. On the other hand, because the overall thickness of the convex lens is not uniform, there is a certain degree of thickness difference between the largest thickness and the smallest thickness on the convex lens. Although the lens made of plastic material has the advantage of light weight, it is found in practice that plastic When the molded lens is shot, the problem of local thickness shrinkage at the maximum thickness of the lens is very obvious. Therefore, the molding accuracy of plastic lenses is not good, and the quality is poor, which will affect the optical effect. In addition, the lens of this convex lens type molded by plastic has a molding time of up to 30 to 40 minutes, a high molding failure rate, and air bubbles and mist in the lens are easy to be generated. Therefore, the known lenses need to be improved.
因此，本發明之目的，即在提供一種兼具重量輕、厚度易控制、品質佳等優點的液態透鏡。Therefore, an object of the present invention is to provide a liquid lens that has advantages of light weight, easy thickness control, and good quality.
於是，本發明液態透鏡，包含一個可透光的外殼，以及一個可透光的液體介質。該外殼包括一個基壁，以及一個連接該基壁且呈弧曲狀的殼壁，該殼壁與該基壁共同界定一個容室。該液體介質填充於該容室。該外殼的折射率為n1，該液體介質的折射率為n2，且∣n1-n2∣≦0.05。Therefore, the liquid lens of the present invention includes a light-transmissive casing and a light-transmissive liquid medium. The shell includes a base wall and an arc-shaped shell wall connected to the base wall, and the shell wall and the base wall together define a containing chamber. The liquid medium is filled in the container. The refractive index of the shell is n1, the refractive index of the liquid medium is n2, and ∣n1-n2∣ ≦ 0.05.
本發明之功效在於：藉由該液體介質填充於該外殼的容室，與該外殼搭配形成透鏡，具有重量輕的優點。而且本發明的外殼厚度較薄、容易製作、成型厚度易控制，可以避免以往塑膠透鏡於厚度較厚處之局部厚度縮水的問題，故本發明液態透鏡的品質佳，能達到所需要的光學效果。The effect of the present invention is that the liquid chamber is filled in the housing of the casing, and the lens is matched with the casing to form a lens, which has the advantage of light weight. In addition, the shell of the present invention is thin, easy to manufacture, and easy to control the molding thickness, which can avoid the problem of shrinking of the local thickness of the conventional plastic lens in the thicker part. Therefore, the liquid lens of the present invention has good quality and can achieve the required optical effect. .
參閱圖1、2、3，本發明液態透鏡之一實施例，可應用於車燈，該車燈例如車頭燈、霧燈等等，本實施例之液態透鏡使用於車燈中，用於將該車燈的一光源的光線導引成適當光形，並使光線通過射出。本實施例之液態透鏡是一個凸透鏡，並包含一個可透光的外殼1，以及一個可透光的液體介質2。Referring to FIGS. 1, 2, and 3, an embodiment of the liquid lens of the present invention can be applied to a vehicle light, such as a headlight, a fog lamp, etc. The liquid lens of this embodiment is used in a vehicle light to The light from a light source of the vehicle light is guided into an appropriate light shape, and the light is emitted through it. The liquid lens of this embodiment is a convex lens, and includes a light-transmissive casing 1 and a light-transmissive liquid medium 2.
該外殼1包括一個基壁11，以及一個周緣連接該基壁11且呈弧曲狀的殼壁12，該殼壁12與該基壁11共同界定一個呈凸透鏡形狀的容室10。該基壁11為一個板片狀，且為非均勻厚度之設計，在本實施例中，該基壁11的中央部位的厚度d1大於其周緣部位的厚度d2。該基壁11包括一朝向該容室10且朝前的第一面111、一相反於該第一面111且朝後的第二面112、連通該容室10的一個注液孔113與一個排氣孔114、二個分別填充於該注液孔113與該排氣孔114的密封膠115，以及一個位於該第一面111的第一組裝部116。該注液孔113與該排氣孔114皆鄰近該基壁11的周緣部位，且彼此互相遠離而間隔相對，該注液孔113與該排氣孔114都是自該第一面111朝該第二面112延伸貫穿。該第一組裝部116為一個凹陷形成於該第一面111的環槽。The housing 1 includes a base wall 11 and an arc-shaped shell wall 12 connected to the base wall 11 at a periphery. The shell wall 12 and the base wall 11 define a receiving chamber 10 having a convex lens shape. The base wall 11 has a plate shape and a non-uniform thickness design. In this embodiment, the thickness d1 of the central portion of the base wall 11 is greater than the thickness d2 of the peripheral portion. The base wall 11 includes a first surface 111 facing the container chamber 10 and facing forward, a second surface 112 opposite to the first surface 111 and facing backward, a liquid injection hole 113 communicating with the container chamber 10 and one The exhaust hole 114, two sealants 115 filled in the liquid injection hole 113 and the exhaust hole 114, and a first assembly portion 116 on the first surface 111. The injection hole 113 and the exhaust hole 114 are both adjacent to the peripheral edge of the base wall 11 and are spaced apart from each other and spaced opposite each other. Both the injection hole 113 and the exhaust hole 114 are directed from the first surface 111 toward the The second surface 112 extends through. The first assembling portion 116 is a ring groove formed in the first surface 111.
該殼壁12包括一個與該基壁11間隔相對的出光部121，以及一個呈環狀並連接於該出光部121與該基壁11間的連接部122。以該殼壁12的整體外型來看，該殼壁12自該連接部122往該出光部121逐漸朝遠離該基壁11的方向(亦即朝前)弧突，使本發明整體形成一個凸透鏡構造。以該殼壁12的厚度來看，其為非均勻厚度之設計，因此該出光部121的厚度d3與該連接部122的厚度d4不相同，具體而言，本實施例的殼壁12厚度自該連接部122往該出光部121逐漸變厚，因此d3大於d4。該殼壁12的最薄部位的厚度大於或等於2mm，該殼壁12的最厚部位的厚度小於或等於5mm。由於該殼壁12厚度太薄時，不易製作成型，而厚度太厚度則容易於射出成型時產生局部性縮水、厚度不足的問題，故該殼壁12的厚度較佳地為上述範圍。The shell wall 12 includes a light emitting portion 121 spaced apart from the base wall 11 and a connecting portion 122 that is annular and connected between the light emitting portion 121 and the base wall 11. Judging from the overall appearance of the shell wall 12, the shell wall 12 gradually projects from the connecting portion 122 to the light emitting portion 121 in a direction away from the base wall 11 (that is, facing forward), so that the present invention forms a whole. Convex lens construction. The thickness of the shell wall 12 is a non-uniform thickness design. Therefore, the thickness d3 of the light emitting portion 121 and the thickness d4 of the connecting portion 122 are different. Specifically, the thickness of the shell wall 12 in this embodiment is The connecting portion 122 gradually becomes thicker toward the light emitting portion 121, so d3 is greater than d4. The thickness of the thinnest part of the shell wall 12 is greater than or equal to 2 mm, and the thickness of the thickest part of the shell wall 12 is less than or equal to 5 mm. When the thickness of the shell wall 12 is too thin, it is not easy to be formed, and the thickness is too easy to cause local shrinkage and insufficient thickness during injection molding. Therefore, the thickness of the shell wall 12 is preferably in the above range.
該殼壁12還包括一個由該出光部121與連接部122共同形成且朝向該基壁11的該第一面111的第一殼面123、一個相反於該第一殼面123並由該出光部121與連接部122共同形成的第二殼面124，以及一個位於該第一殼面123並用於與該第一組裝部116嵌卡結合的第二組裝部125。該第二組裝部125為一個形成於該第一殼面123鄰近周緣處且朝該基壁11的第一組裝部116卡入的突環。於實施時，該第二組裝部125不以一環為限制，例如也可以包括二個間隔的突塊，此時該第一組裝部116可以包括二個間隔並分別供該等突塊卡入的凹槽，此外，該第二組裝部125與第一組裝部116的凹凸結構也可以互換。亦即，本發明的第二組裝部125與第一組裝部116的凹凸結構與結構數量不須限制，只要能使該基壁11與殼壁12組裝結合在一起即可。The shell wall 12 further includes a first shell surface 123 formed by the light emitting portion 121 and the connection portion 122 and facing the first surface 111 of the base wall 11, and a first shell surface 123 opposite to the first shell surface 123 and emitting light. The second shell surface 124 formed by the portion 121 and the connecting portion 122 together, and a second assembly portion 125 located on the first shell surface 123 and used for inserting and coupling with the first assembly portion 116. The second assembling part 125 is a protruding ring formed on the first shell surface 123 adjacent to the peripheral edge and snapping toward the first assembling part 116 of the base wall 11. During implementation, the second assembly portion 125 is not limited to one ring. For example, the second assembly portion 125 may also include two spaced protrusions. At this time, the first assembly portion 116 may include two spaces and the protrusions are respectively locked into the protrusions. In addition, the concave-convex structure of the second assembling part 125 and the first assembling part 116 can be interchanged. That is, the concave-convex structure and the number of structures of the second assembling portion 125 and the first assembling portion 116 of the present invention are not limited, as long as the base wall 11 and the shell wall 12 can be assembled and combined together.
需要說明的是，本實施例的外殼1是由該基壁11與該殼壁12結合構成，但於實施時，該外殼1整體也可以為一體成型。該外殼1材質(包含該基壁11與該殼壁12材質)為可透光的高分子材料，例如壓克力(PMMA)、聚碳酸酯(PC)等等，本實施例是使用壓克力，其折射率約為1.47~1.55。It should be noted that the casing 1 of this embodiment is formed by combining the base wall 11 and the casing wall 12, but during implementation, the entire casing 1 may be integrally formed. The material of the housing 1 (including the material of the base wall 11 and the shell wall 12) is a light-transmissive polymer material, such as acrylic (PMMA), polycarbonate (PC), etc. This embodiment uses acrylic Force, its refractive index is about 1.47 ~ 1.55.
該液體介質2填充於該容室10，其折射率與該外殼1的折射率不可差異過大，以減少液體與該外殼1因不同材質間所造成的光折射效果之差異，以降低光學性能的輸出損耗。因此，該外殼1的折射率為n1，該液體介質2的折射率為n2，且∣n1-n2∣≦0.05。該液體介質2為透明液體，或者選用與該外殼1之PMMA、PC材料顏色接近之液體。該液體介質2可以使用不易揮發、沸點高、凝固點低的液體，使本發明可適用於高溫、低溫與各種環境中。也就是說，本發明該液體介質2為一種與該外殼1折射率接近(符合∣n1-n2∣≦0.05)，並能達到車燈所須的光學效果的光學液體。The liquid medium 2 is filled in the containing chamber 10, and the refractive index of the liquid medium 2 and the refractive index of the housing 1 cannot be too large, so as to reduce the difference in the light refraction effect caused by the liquid and the housing 1 due to different materials, so as to reduce the optical performance Output loss. Therefore, the refractive index of the casing 1 is n1, the refractive index of the liquid medium 2 is n2, and ∣n1-n2∣ ≦ 0.05. The liquid medium 2 is a transparent liquid, or a liquid close to the color of the PMMA and PC materials of the casing 1 is selected. The liquid medium 2 can be a liquid that is not easily volatile, has a high boiling point, and has a low freezing point, so that the present invention can be applied to high temperature, low temperature, and various environments. In other words, the liquid medium 2 of the present invention is an optical liquid having a refractive index close to that of the casing 1 (in accordance with ∣n1-n2∣ ≦ 0.05) and capable of achieving the optical effect required by a vehicle lamp.
本發明製作時，該基壁11與該殼壁12可以利用塑膠射出成型方式製作，再將該基壁11與該殼壁12組裝結合，進一步地可利用膠體將兩者黏著固定。接著自該注液孔113注入該液體介質2，使該液體介質2填充該容室10，注液的過程中，該容室10中的空氣則自該排氣孔114向外排出。將該液體介質2填滿該容室10後，再將具有黏性的膠體注入該注液孔113與該排氣孔114，進而形成該等密封膠115，以將該等孔洞黏著密封住，使該容室10成為密閉空間，該液體介質2能穩定且不外漏地填充於其中。藉由該液體介質2填充於凸透鏡形狀的該容室10，使本發明形成一個液態凸透鏡。In the production of the present invention, the base wall 11 and the shell wall 12 can be manufactured by plastic injection molding, and then the base wall 11 and the shell wall 12 are assembled and combined, and the two can be adhered and fixed by using gel. Then, the liquid medium 2 is injected from the liquid injection hole 113 so that the liquid medium 2 fills the chamber 10. During the process of liquid injection, the air in the chamber 10 is exhausted from the exhaust hole 114. After the liquid medium 2 is filled in the chamber 10, viscous colloid is injected into the liquid injection hole 113 and the exhaust hole 114, and the sealants 115 are formed to seal the holes. By making the container chamber 10 a closed space, the liquid medium 2 can be filled therein stably without leaking. The liquid medium 2 is filled in the container 10 in the shape of a convex lens, so that the present invention forms a liquid convex lens.
本實施例之液態透鏡作為車燈透鏡使用時，光線由該基壁11的該第二面112進入，經由該液體介質2的折射與導引後，再由該殼壁12的該第二殼面124向外射出，並且形成符合法規要求之光形與亮度。由於液體介質2與該外殼1的折射率差異過大時，會造成光線於不同介質間產生明顯的折射，可能造成透鏡無法聚焦、光學效果變差，故本發明除了限定∣n1-n2∣≦0.05以外，更進一步地，該基壁11的中央部位的厚度d1大於其周緣部位的厚度d2，以及該殼壁12的該出光部121厚度d3大於連接部122的厚度d4，也是為了修正該液體介質2與該外殼1間的折射率差異所造成的光學差異，使本發明可以良好聚焦，達到預定的光學效果。其中，光線由該殼壁12射出時，經由該出光部121相對於該連接部122射出的光較多，而當該外殼1之固體部分的厚度增加時，更有利於補償上述固體與液體間的光學差異，因此本實施例在設計該外殼1的厚度變化時，才需要將該出光部121設計的比該連接部122厚(即d3＞d4)，而該基壁11的中央部位對應於光線通過量較多的該出光部121，故該基壁11的中央部位設計的比其周緣部位厚(即d1＞d2)。When the liquid lens of this embodiment is used as a lamp lens of a vehicle, light enters through the second surface 112 of the base wall 11, and is refracted and guided by the liquid medium 2, and then passes through the second shell of the shell wall 12. The surface 124 emits outwards, and forms a light shape and brightness that meet the requirements of regulations. When the refractive index difference between the liquid medium 2 and the casing 1 is too large, it will cause obvious refraction of light between different media, which may cause the lens to fail to focus and the optical effect to be deteriorated. Therefore, the present invention limits ∣n1-n2∣ ≦ 0.05 In addition, further, the thickness d1 of the central portion of the base wall 11 is greater than the thickness d2 of its peripheral portion, and the thickness d3 of the light emitting portion 121 of the shell wall 12 is greater than the thickness d4 of the connecting portion 122. This is also to modify the liquid medium. The optical difference caused by the refractive index difference between 2 and the casing 1 enables the present invention to focus well and achieve a predetermined optical effect. Among them, when light is emitted from the shell wall 12, more light is emitted through the light emitting portion 121 relative to the connecting portion 122, and when the thickness of the solid portion of the housing 1 is increased, it is more beneficial to compensate the above-mentioned solid-liquid space. Therefore, when the thickness of the casing 1 is designed to be changed in this embodiment, it is necessary to design the light emitting portion 121 to be thicker than the connecting portion 122 (that is, d3> d4), and the central portion of the base wall 11 corresponds to Since the light emitting portion 121 has a large amount of light passing through, the central portion of the base wall 11 is designed to be thicker than its peripheral portion (ie, d1> d2).
綜上所述，藉由該液體介質2填充於該外殼1的容室10，與該外殼1搭配形成透鏡，具有重量輕的優點，可以改善以往玻璃透鏡過重的問題。另外，相較於以往的塑膠透鏡，本發明的外殼1厚度較薄、容易製作、成型厚度易控制，可以避免以往塑膠透鏡於厚度較厚處之局部厚度縮水的問題，成型時間也相對較短、良率高。再搭配該外殼1與該液體介質2間的折射率差值關係，使本發明液態透鏡整體之折射與導光效果佳，能達到所需要的光學效果。To sum up, filling the container 10 of the casing 1 with the liquid medium 2 to form a lens with the casing 1 has the advantage of light weight, which can improve the problem of overweight glass lenses in the past. In addition, compared with the conventional plastic lens, the casing 1 of the present invention is thinner, easier to manufacture, and easier to control the molding thickness, which can avoid the problem of local thickness shrinkage of the conventional plastic lens in the thicker part, and the molding time is relatively short. High yield. Together with the refractive index difference relationship between the casing 1 and the liquid medium 2, the overall refractive and light guiding effect of the liquid lens of the present invention is good, and the required optical effect can be achieved.
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，凡是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 are only examples of the present invention. When the scope of implementation of the present invention cannot be limited in this way, any simple equivalent changes and modifications made in accordance with the scope of the patent application and the content of the patent specification of the present invention are still Within the scope of the invention patent.
