The optical component (not separately labeled) is applied to at least one of the light-emitting diodes, thereby changing the light intensity distribution of the light emitted by the light-emitting diode (ie, changing the light pattern of the light emitted by the light-emitting diode).
光學元件包含光學透鏡1，光學透鏡1是使用塑膠、玻璃、矽膠(silicone)或其他可透光材料製作而成，並具有一入光部10及一連接於入光部10的出光部12。出光部12呈圓盤狀，出光部12的外徑大於入光部10的外徑，入光部10的外徑隨著遠離出光部12而遞減，入光部10在相反連接出光部12處由內而外形成有一凹槽100、複數導光區102及一全反射區103，導光區102呈同心圓狀環繞凹槽100，全反射區103環繞導光區102。入光部10更包含一底面101，凹槽100及導光區102分別由底面101朝向出光部12的方向凹陷。入光部10及出光部12為一體成型。 The optical element comprises an optical lens 1 which is made of plastic, glass, silicone or other light transmissive material, and has a light incident portion 10 and a light exit portion 12 connected to the light incident portion 10. The light exit portion 12 has a disk shape, and the outer diameter of the light exit portion 12 is larger than the outer diameter of the light incident portion 10. The outer diameter of the light incident portion 10 decreases as it goes away from the light exit portion 12, and the light incident portion 10 is connected to the light exit portion 12 oppositely. A groove 100, a plurality of light guiding regions 102 and a total reflection region 103 are formed from the inside to the outside. The light guiding region 102 surrounds the groove 100 concentrically, and the total reflection region 103 surrounds the light guiding region 102. The light incident portion 10 further includes a bottom surface 101, and the groove 100 and the light guiding region 102 are respectively recessed from the bottom surface 101 toward the light exit portion 12. The light incident portion 10 and the light exit portion 12 are integrally formed.
導光區102的厚度隨著遠離出光部12遞減，從光學透鏡1的側剖面 觀之，導光區102大致呈錐形。發光元件設置於入光部10，並位於凹槽100下方。導光區102用以使發光元件產生的呈發散狀的光線得以朝向出光部12的方向傳遞，其中，導光區102主要是藉由全反射原理而改變光線的傳遞方向。 The thickness of the light guiding region 102 decreases as it moves away from the light exit portion 12, and the side profile from the optical lens 1 Viewed, the light guiding region 102 is generally tapered. The light emitting element is disposed on the light incident portion 10 and located below the groove 100. The light guiding region 102 is configured to transmit the divergent light generated by the light emitting element toward the light exiting portion 12, wherein the light guiding region 102 mainly changes the light transmitting direction by the principle of total reflection.
在本實施方式中，光學透鏡1包含三個導光區102，然在實際實施時，導光區102的數量可以依據實際需求的照度、發光角度及光均勻度而調整。如圖2所示，最靠近凹槽100的導光區102的底端與底面101兩者之間具有第一距離d1，並具有第一寬度w1及第一高度h1；次靠近凹槽100的導光區102的底端與底面101兩者之間具有一第二距離d2，並具有第二寬度w2及第二高度h2；最遠離凹槽100的導光區102的底端與底面101兩者之間具有一第三距離為d3，並具有第三寬度w3及第三高度h3。 In the present embodiment, the optical lens 1 includes three light guiding regions 102. However, in actual implementation, the number of light guiding regions 102 can be adjusted according to actual required illumination, illumination angle, and light uniformity. As shown in FIG. 2, the bottom end of the light guiding region 102 closest to the groove 100 has a first distance d1 between the bottom end and the bottom surface 101, and has a first width w1 and a first height h1; The bottom end of the light guiding area 102 has a second distance d2 between the bottom end and the bottom surface 101, and has a second width w2 and a second height h2; the bottom end of the light guiding area 102 farthest from the groove 100 and the bottom surface 101 There is a third distance d3 between the three, and a third width w3 and a third height h3.
第二寬度w2相同於第一寬度w1，第三寬度w3亦相同於第一寬度w1；換言之，該些導光區102具有相同寬度。第二高度h2相同於第一高度h1，第三高度h3亦相同於第一高度h1；換言之，該些導光區102具有相同高度。第一距離d1小於第二距離d2，第二距離d2小於第三距離d3；換言之，該些導光區102與底面101的距離隨著遠離光學透鏡1的一中心軸線而遞增。 The second width w2 is the same as the first width w1, and the third width w3 is also the same as the first width w1; in other words, the light guiding regions 102 have the same width. The second height h2 is the same as the first height h1, and the third height h3 is also the same as the first height h1; in other words, the light guiding regions 102 have the same height. The first distance d1 is smaller than the second distance d2, and the second distance d2 is smaller than the third distance d3; in other words, the distance between the light guiding regions 102 and the bottom surface 101 increases as moving away from a central axis of the optical lens 1.
入光部10包含頂壁104及環繞壁108，環繞壁108為全反射區103與導光區102相鄰接的表面，環繞壁108由複數相鄰接的微透鏡110組成。在本實施方式中，微透鏡110分別呈凸弧柱狀，並可與中心軸線平行或夾一角度，且朝向光學透鏡1的中心軸線方向輻射狀凸設。其中，前述中心軸線可例如為光學透鏡1的光線，且光學透鏡1以中心軸線為中心並對稱於中心軸線設置。微透鏡110的 設計可以改變光線的傳遞路徑，進而提供混光效果，並可有效地增加視覺的美觀度。入光部10更包含交錯排列於頂壁104及環繞壁108之間的第一連接壁111及第二連接壁112。頂壁104與其中之一第一連接壁111相鄰接，且頂壁104與第一連接壁之間的夾角θ為大於九十度的鈍角。在實際應用時，夾角θ也可以依據實際需求而設計為直角。 The light incident portion 10 includes a top wall 104 and a surrounding wall 108. The surrounding wall 108 is a surface where the total reflection region 103 is adjacent to the light guiding region 102. The surrounding wall 108 is composed of a plurality of adjacent microlenses 110. In the present embodiment, the microlenses 110 are each formed in a convex arc shape and may be parallel or at an angle to the central axis, and are radially convex toward the central axis of the optical lens 1. Wherein, the aforementioned central axis may be, for example, the light of the optical lens 1, and the optical lens 1 is centered on the central axis and disposed symmetrically with respect to the central axis. Microlens 110 The design can change the light transmission path, which provides a light mixing effect and can effectively increase the visual aesthetics. The light incident portion 10 further includes a first connecting wall 111 and a second connecting wall 112 that are alternately arranged between the top wall 104 and the surrounding wall 108. The top wall 104 is adjacent to one of the first connecting walls 111, and the angle θ between the top wall 104 and the first connecting wall is an obtuse angle greater than ninety degrees. In practical applications, the angle θ can also be designed as a right angle according to actual needs.
配合參閱圖3及圖4，為本創作第二實施例之光學元件之立體圖及剖視圖。圖3及圖4所示之光學元件中，光學透鏡1a與第一實施例的光學透鏡1類似，且相同的元件標示以相同的符號。值得注意的是，兩者的差異在於入光部10的設計。 3 and 4 are a perspective view and a cross-sectional view of an optical component according to a second embodiment of the present invention. In the optical elements shown in Figs. 3 and 4, the optical lens 1a is similar to the optical lens 1 of the first embodiment, and the same elements are designated by the same reference numerals. It is worth noting that the difference between the two lies in the design of the light entering section 10.
在本實施方式中，入光部10a的的凹槽100a的頂壁104a設計為凸面，並朝向相反於出光部12的方向凸出，藉此，可以有效地會聚通過的光線。 In the present embodiment, the top wall 104a of the groove 100a of the light incident portion 10a is designed to be convex and protrudes in a direction opposite to the light exit portion 12, whereby the passing light can be effectively concentrated.
此外，在本實施方式中，導光區102a分別具有不同的寬度及不同的高度。其中，最鄰近凹槽100a的導光區102a具有第一寬度w1及第一高度h1，次鄰近凹槽100a的導光區102a具有第二寬度w2及第二高度h2，最遠離凹槽100a的導光區102a具有第三寬度w3及第三高度h3。該些導光區102a具有不同寬度，第二寬度w2大於第一寬度w1，第三寬度w3大於第一寬度w1。該些導光區102a具有不同高度，其中第二高度h2大於第一高度h1，第一高度h1小於第三高度h3。又，該些導光區102a的底端與底面101兩者之間的距離皆為d。 Further, in the present embodiment, the light guiding regions 102a have different widths and different heights, respectively. The light guiding area 102a closest to the groove 100a has a first width w1 and a first height h1, and the light guiding area 102a of the second adjacent groove 100a has a second width w2 and a second height h2, which is farthest from the groove 100a. The light guiding region 102a has a third width w3 and a third height h3.

The light guiding regions 102a have different heights, wherein the second height h2 is greater than the first height h1, and the first height h1 is smaller than the third height h3. Moreover, the distance between the bottom end of the light guiding regions 102a and the bottom surface 101 is d.
導光區102a主要是藉由全反射原理以改變光線的傳遞方向，因導 光區102a具有不同的寬度及高度，可以讓傳遞於其上的光線的全反射角度具差異性，故能有效地改變通過之光線的均勻度。光學透鏡1a的其他元件之功用與相關說明，實際上與第一實施例的光學透鏡1相同，在此不予贅述。 The light guiding region 102a mainly changes the direction of light transmission by the principle of total reflection. The light regions 102a have different widths and heights, so that the total reflection angle of the light transmitted thereto is different, so that the uniformity of the passing light can be effectively changed. The functions and related descriptions of the other elements of the optical lens 1a are substantially the same as those of the optical lens 1 of the first embodiment, and will not be described herein.

In the optical element shown in Fig. 5, the optical lens 1b is similar to the optical lens 1 of the first embodiment, and the same elements are denoted by the same reference numerals. It is worth noting that the difference between the two lies in the design of the light incident portion 10b.
在本實施方式中，入光部10b(未圖示)的凹槽100b的頂壁104b設計為凹面，並朝向出光部12的方向凹陷，藉此，可以發散通過的光線。 In the present embodiment, the top wall 104b of the groove 100b of the light incident portion 10b (not shown) is designed to be concave and recessed toward the light exit portion 12, whereby the passing light can be scattered.

The second width w2 is the same as the first width w1, and the third width w3 is also the same as the first width w1; in other words, the light guiding regions 102b have the same width. The second height h2 is greater than the first height h1, and the third height h3 is greater than the first height h1; in other words, the heights of the light guiding regions 102b increase as they move away from the groove 100b. The first distance d1 is greater than the second distance d2, and the second distance d2 is greater than the third distance d3; in other words, the distance between the light guiding regions 102 and the bottom surface 101 decreases as moving away from the central axis of the optical lens 1b. The functions and related descriptions of the other elements of the optical lens 1b are substantially the same as those of the optical lens 1 of the first embodiment, and will not be described herein.
