The main function of the reflector is to direct the light from the bulb to the desired direction and to change the light pattern produced when the bulb is illuminated. However, the variability of changing the light pattern by the reflector is not large, and the light pattern is usually in the form of condensing, which is limited in application.
另外一种传统灯具是通过光源搭配二次光学组件,来达到改变光型的目的。然而,此种架构必须在二次光学组件中央设置凹孔,并且将光源放置在凹孔中来达到调整光型的目的。因此,二次光学组件必须配合不同形式或不同数量的光源来改变整个组件架构的设计,因而导致成本的增加。Another conventional luminaire is to change the light type by using a light source with a secondary optical component. However, such an architecture must provide a recess in the center of the secondary optical component and place the light source in the recess to achieve the purpose of adjusting the light pattern. Therefore, the secondary optical component must match different forms or different numbers of light sources to change the design of the entire component architecture, thus resulting in an increase in cost.

In the present embodiment, the light guiding assembly 100 is adapted to guide the light to be totally reflected in the light guiding assembly 100 to cause the light to produce different beam angles. Light referred to herein is derived from a light source, such as a light emitting diode. The light guide assembly 100 has an annular frustum and has a through hole 110. The light guide assembly 100 includes a first end surface 112, a second end surface 114, an outer surface 116, and an inner surface 118. The first end surface 112 and the second end surface 114 may be a light incident surface and a light exit surface, respectively, and the outer surface 116 and the inner surface 118 may be reflective surfaces. The through hole 110 defines a first opening 110a in the first end surface 112, and the first end surface 112 has a first outer circumference 112a and a first inner circumference 112b. The second end surface 114 is opposite to the first end surface 112. The through hole 110 defines a second opening 110b in the second end surface 114, and the second end surface 114 has a second outer circumference 114a and a second inner circumference 114b. That is, the first opening 110a and the second opening 110b communicate with each other, while the first inner circumference 112b defines a first opening 110a and the second inner circumference 114b defines a second opening 110b. As shown in FIG. 1A and FIG. 1B, the area of the first opening 110a is larger than the area of the second opening 110b, and the area of the first end surface 112 is smaller than the area of the second end surface 114.
外表面116连接第一外周缘112a及第二外周缘114a,且外表面116是由第一外形曲线B1所建构的曲面。如图1A及图1B所示,外表面116从第一端面112的第一外周缘112a向外扩张延伸而连接到第二端面114的第二外周缘114a。其中,第一外形曲线B1由第一外周缘112a上的第一起始点P0与第二外周缘114a上第一终止点P2联机所形成。更具体地,本实施方式中的第一外形曲线B1是定义在通过导光组件100的中心并且垂直第一端面112的任何剖切面与外表面116交集所形成的曲线。内表
面118连接第一内周缘112b及第二内周缘114b,且内表面118是由第二外形曲线B2所建构的曲面。其中,第二外形曲线B2由第一内周缘112b上的第二起始点P0’与第二内周缘114b上第二终止点P2’联机所形成。同样地,本实施方式中的第二外形曲线B2是定义在通过导光组件100的中心并且垂直第一端面112的任何剖切面与内表面118交集所形成的曲线。The outer surface 116 connects the first outer circumference 112a and the second outer circumference 114a, and the outer surface 116 is a curved surface constructed by the first contour curve B1. As shown in FIGS. 1A and 1B, the outer surface 116 extends outwardly from the first outer periphery 112a of the first end surface 112 to connect to the second outer periphery 114a of the second end surface 114. The first contour curve B1 is formed by the first starting point P 0 on the first outer circumference 112a and the first ending point P 2 on the second outer circumference 114a. More specifically, the first profile B1 in the present embodiment is a curve defined by the intersection of any of the cut planes passing through the center of the light guide assembly 100 and perpendicular to the first end face 112 and the outer surface 116. The inner surface 118 connects the first inner circumference 112b and the second inner circumference 114b, and the inner surface 118 is a curved surface constructed by the second outer shape curve B2. The second contour curve B2 is formed by the second starting point P 0 ' on the first inner circumference 112b and the second ending point P 2 ' on the second inner circumference 114b. Likewise, the second profile B2 in the present embodiment is a curve defined by the intersection of any of the cut planes passing through the center of the light guide assembly 100 and perpendicular to the first end face 112 and the inner surface 118.
在实施例中,第一外形曲线B1由贝塞尔曲线函数所定义出。贝塞尔曲线主要是利用3个以上的点位置先行定义坐标后,再根据不同的权重所绘制出的不同曲线。其中,贝塞尔曲线函数为:In an embodiment, the first profile curve B1 is defined by a Bezier curve function. The Bezier curve mainly uses three or more point positions to define the coordinates first, and then draws different curves according to different weights. Among them, the Bezier curve function is:
其中,Pi代表贝塞尔曲线函数中第i点的坐标。在第一起始点P0与第一终止点P2之间具有至少一个第一控制点P1。其中,此至少一个第一控制点P1主要是用来决定第一外形曲线B1的弧度。另外,当第一控制点的总点数为1时,定义第一起始点P0的位置坐标P0=(X0,Y0),至少一个第一控制点P1的位置坐标P1=(X1,Y1),第一终止点P2的位置坐标P2=(X2,Y2)。在贝塞尔曲线函数中,数值n为至少一个第一控制点P1的总点数+1所得到的值。举例而言,当此至少一个第一控制点有二个时,数值n即为3。此外,W1为第一控制点P1的权重,其可调节曲线使其趋近于随意形状。如图1B所示,第一起始点P0与第一控制点P1的联机定义权重W1=1,第一起始点P0与第一终止点P2的联机定义权重W1=0。当权重W1越接近1,则第一外形曲线B1将会偏向第一起始点P0与第一控制点P1的联机。当权重W1越接近0,则第一外形曲线B1将会偏向第一起始点P0与第一终止点P2的联机。贝塞尔曲线函数的t为默认点至第一起始点P0的长度与总长的比值。前述总长为第一起始点P0至第一终止点P2所形成曲线的总
长度。由此可知,t可以表示在第一外形曲线B1上位于第一起始点P0与第一终止点P2之间的任一点的位置对应值。Where P i represents the coordinates of the i-th point in the Bezier curve function. There is at least one first control point P 1 between the first starting point P 0 and the first ending point P 2 . The at least one first control point P 1 is mainly used to determine the curvature of the first contour curve B1. Further, when the total number of points for a first control point, defining a first starting point position coordinates P 0 P 0 = (X 0, Y 0), controlling at least a first coordinate of point P 1 P 1 = (X 1 , Y 1 ), the position coordinate P 2 of the first end point P 2 is (X 2 , Y 2 ). In the Bezier curve function, the value n is the value obtained by the total number of points +1 of at least one first control point P 1 . For example, when there are two at least one first control point, the value n is 3. Furthermore, W 1 is the weight of the first control point P 1 which adjusts the curve to approximate the random shape. 1B, the first starting point and a first control point P 0 P line defined weight of 1 W 1 = 1, the first starting point P 0 and the end point of the first line P defined weight of 2 W 1 = 0. When the weight W 1 is closer to 1, the first contour curve B1 will be biased toward the first starting point P 0 and the first control point P 1 . When the weight W 1 is closer to 0, the first contour curve B1 will be biased toward the first starting point P 0 and the first end point P 2 . The t of the Bezier curve function is the ratio of the length of the default point to the first starting point P 0 to the total length. The aforementioned total length is the total length of the curve formed by the first starting point P 0 to the first ending point P 2 . It can be seen that t can represent the position corresponding value of any point between the first starting point P 0 and the first ending point P 2 on the first contour curve B1.
在定义完第一起始点P0、第一控制点P1及第一终止点P2后,本发明的实施方式进一步界定第一外形曲线B1的限制如下:After defining the first starting point P 0 , the first control point P 1 and the first ending point P 2 , embodiments of the present invention further define the limitations of the first contour curve B1 as follows:
X0≦X1≦X2
X 0 ≦X 1 ≦X 2
90°≧α1≧α2
90°≧α 1 ≧α 2
0≦α1=θ1+θ2﹣90°0≦α 1 =θ 1 +θ 2 -90°
θ2≧90°﹣θ1
θ 2 ≧90°-θ 1
0≦Wi≦10≦W i ≦1
继续参阅图1B,α1为第一起始点P0与第一控制点P1联机与水平线的夹角,α2为第一起始点P0与第一终止点P2联机与水平线的夹角。θ1为光线由外界进入导光组件100中的折射角,θ2为光线进入导光组件100后射向外表面116的入射角,nmaterial为导光组件100材料的折射率。藉此,调整第一外形曲线B1的各参数值可改变整个外表面116的形状。Continuing to refer to FIG. 1B, α 1 is the angle between the first starting point P 0 and the first control point P 1 and the horizontal line, and α 2 is the angle between the first starting point P 0 and the first ending point P 2 and the horizontal line. θ 1 is the angle of refraction of the light entering the light guiding component 100 from the outside, θ 2 is the incident angle of the light entering the light guiding component 100 and then emitting to the outer surface 116, and n material is the refractive index of the material of the light guiding component 100. Thereby, adjusting the respective parameter values of the first profile curve B1 can change the shape of the entire outer surface 116.
再次参阅图1A及图1B,在实施例中,第二外形曲线B2可与第一外形曲线B1相同,均由上述贝塞尔曲线函数所定义出。Referring again to FIGS. 1A and 1B, in an embodiment, the second profile curve B2 may be the same as the first profile curve B1, both defined by the Bessel curve function described above.
其中,在第二起始点P0’与第二终止点P2’之间具有至少一个第二控制点P1’。其中,此至少一个第二控制点P1’主要是用来决定第二外形曲线B2的弧度。另外,当第二控制点的总点数为1时,定义第二起始点P0’的位置坐标P0’=(X0’,Y0’),至少一个第二控制点P1’的位置坐标P1’=(X1’,Y1’),第二终止点P2’的位置坐标P2’=(X2’,Y2’)。在此贝塞尔曲线函数中,数值n为至少一个第二控制点P1’的总点数+1所得到的值。另外,W1为第二控制点P1’的权重,其可调节曲线使其趋近于随意形状。如图1B所
示,第二起始点P0’与第二控制点P1’的联机定义权重W1=1,第二起始点P0’与第二终止点P2’的联机定义权重W1=0。当权重W1越接近1,则第二外形曲线B2将会偏向第二起始点P0’与第二控制点P1’的联机。当权重W1越接近0,则第二外形曲线B2将会偏向第二起始点P0’与第二终止点P2’的联机。贝塞尔曲线函数的t为默认点至第二起始点P0’的长度与总长的比值。前述总长为第二起始点P0’至第二终止点P2’所形成曲线的总长度。由此可知,t可以表示在第二外形曲线B2上位于第二起始点P0’与第二终止点P2’之间的任一点的位置对应值。Therein, there is at least one second control point P 1 ' between the second starting point P 0 ' and the second ending point P 2 '. The at least one second control point P 1 ′ is mainly used to determine the curvature of the second contour curve B2. In addition, when the total number of points of the second control point is 1, the position coordinate P 0 '=(X 0 ', Y 0 ') of the second starting point P 0 ', and the position of the at least one second control point P 1 ' are defined. The coordinate P 1 '=(X 1 ', Y 1 '), the position coordinate P 2 '=(X 2 ', Y 2 ') of the second end point P 2 '. In this Bezier curve function, the value n is the value obtained by the total number of points +1 of at least one second control point P 1 '. In addition, W 1 is the weight of the second control point P 1 ', which can adjust the curve to approach the random shape. As shown in FIG. 1B, the online definition weight W 1 =1 of the second starting point P 0 ′ and the second control point P 1 ′, and the online definition weight W of the second starting point P 0 ′ and the second ending point P 2 ′ 1 =0. When the weight W 1 is closer to 1, the second contour curve B2 will be biased toward the second starting point P 0 ' and the second control point P 1 '. When the weight W 1 is closer to 0, the second contour curve B2 will be biased toward the second starting point P 0 ' and the second ending point P 2 '. The t of the Bezier curve function is the ratio of the length of the default point to the second starting point P 0 ' to the total length. The aforementioned total length is the total length of the curve formed by the second starting point P 0 ' to the second ending point P 2 '. It can be seen that t can represent the position corresponding value of any point between the second starting point P 0 ' and the second ending point P 2 ' on the second contour curve B2.
在定义完第二起始点P0’、第二控制点P1’及第二终止点P2’后,本发明的实施方式进一步界定第二外形曲线B2的限制如下:After defining the second starting point P 0 ', the second control point P 1 ', and the second ending point P 2 ', embodiments of the present invention further define the limitations of the second contour curve B2 as follows:
X0’≦X1’≦X2’X 0 '≦X 1 '≦X 2 '
90°≧α1’≧α2’90°≧α 1 '≧α 2 '
0≦α1’=θ1’+θ2’﹣90°0≦α 1 '=θ 1 '+θ 2 '-90°
θ2’≧90°﹣θ1’θ 2 '≧90°-θ 1 '
0≦Wi≦10≦W i ≦1
同时搭配图1B所示,α1’为第二起始点P0’与第二控制点P1’联机与水平线的夹角,α2’为第二起始点P0’与第二终止点P2’联机与水平线的夹角。θ1’为光线由外界进入导光组件100中的折射角,θ2’为光线进入导光组件100后射向内表面118的入射角,nmaterial为导光组件100材料的折射率。藉此,调整第二外形曲线B2的各参数值可改变整个内表面118的形状。At the same time, as shown in FIG. 1B, α 1 ' is the angle between the second starting point P 0 ' and the second control point P 1 'on the horizontal line, and α 2 ' is the second starting point P 0 ' and the second ending point P. 2 'The angle between the line and the horizontal line. θ 1 ' is the angle of refraction into the light guiding component 100 from the outside, θ 2 ' is the incident angle of the light entering the light guiding component 100 and then incident on the inner surface 118, and n material is the refractive index of the material of the light guiding component 100. Thereby, adjusting the respective parameter values of the second profile curve B2 can change the shape of the entire inner surface 118.
由上述可知,第二外形曲线B2与第一外形曲线B1同样是以贝塞尔曲线函数所定义,且限制范围亦相同。故在实施例中,第二外形曲线B2与第一外形曲线B1可为同一曲线,使外表面116
与内表面118呈对称。然,在另一实施例中,第二外形曲线B2与第一外形曲线B1可通过不同的参数设定,来形成不同的曲线,使外表面116与内表面118呈现不对称。除此之外,导光组件的外表面116是从第一端面112的该第一外周缘112a向外扩张延伸而连接到第二端面的第二外周缘114a,内表面118是从第一端面112的该第一内周缘112b向内扩张而连接到第二端面114的第二内周缘114b。藉此设计,光线由第一端面112进入至导光组件100中,在导光组件100中经反射后,由第二端面114发射出去。As can be seen from the above, the second contour curve B2 is defined by the Bezier function as well as the first contour curve B1, and the limitation range is also the same. Therefore, in the embodiment, the second outer shape curve B2 and the first outer shape curve B1 may be the same curve, so that the outer surface 116
It is symmetrical with the inner surface 118. However, in another embodiment, the second profile curve B2 and the first profile curve B1 can be set by different parameters to form different curves, such that the outer surface 116 and the inner surface 118 are asymmetrical. In addition, the outer surface 116 of the light guiding assembly is a second outer peripheral edge 114a that extends outwardly from the first outer peripheral edge 112a of the first end surface 112 and is connected to the second end surface. The inner surface 118 is from the first end surface. The first inner periphery 112b of the 112 is inwardly expanded to be coupled to the second inner periphery 114b of the second end surface 114. By this design, the light enters the light guiding component 100 from the first end surface 112, is reflected by the light guiding component 100, and is emitted by the second end surface 114.

In the present embodiment, inner surface 418 has a first expanded section 418a and a second expanded section 418b. Outer surface 416 also has a first expanded section 416a and a second expanded section 416b. In the present embodiment, as shown in FIG. 4B, the inner surface 418 is inwardly expanded from the first end surface 412 and then expanded outwardly to the second end surface 414, and the outer surface 416 is outwardly expanded from the first end surface 412. It then expands inwardly to the second end face 414, thereby forming first expanded segments 418a and 416a and second expanded segments 418b and 416b.

在第五实施方式中,导光组件500的与导光组件100类似,导光组件500包括第一端面512、第二端面514、外表面516以及内表面518。其中,外表面516以及内表面518与导光组件100的外表面116及内表面118相同,同样是以第一外形曲线B1及第二外形曲线B2所建构而成,故在此不赘述。在本实施方式中,第二端面514具有外周缘514a及内周缘514b,且第二端面514是由第三外形曲线B3所建构的曲面。其中,第三外形曲线B3由外周缘514a上的第三起始点P3与内周缘514b上的第三终止点P5联机所形成。In the fifth embodiment, the light guiding assembly 500 is similar to the light guiding assembly 100. The light guiding assembly 500 includes a first end surface 512, a second end surface 514, an outer surface 516, and an inner surface 518. The outer surface 516 and the inner surface 518 are the same as the outer surface 116 and the inner surface 118 of the light guide assembly 100, and are also constructed by the first outer shape curve B1 and the second outer shape curve B2, and thus are not described herein. In the present embodiment, the second end surface 514 has an outer peripheral edge 514a and an inner peripheral edge 514b, and the second end surface 514 is a curved surface constructed by the third outer shape curve B3. The third contour curve B3 is formed by the third starting point P 3 on the outer circumference 514a and the third ending point P 5 on the inner circumference 514b.
更具体地,本实施方式中的第三外形曲线B3,是定义在通过导光组件500的中心并且垂直第一端面512的任何剖切面与第二端面514交集所形成的曲线。在实施例中,第三外形曲线B3可与第一外形曲线B1相同,均由上述贝塞尔曲线函数所定义出。More specifically, the third outline curve B3 in the present embodiment is a curve defined by the intersection of any cut surface passing through the center of the light guiding member 500 and perpendicular to the first end surface 512 and the second end surface 514. In an embodiment, the third profile curve B3 may be the same as the first profile curve B1, both defined by the Bezier curve function described above.
其中,在第三起始点P3与第三终止点P5之间具有至少一个第三控制点P4。其中,第三控制点P4主要是用来决定第三外形曲线B3的弧度。另外,当第三控制点的总点数为1时,定义第三起始点P3的位置坐标P3=(X3,Y3),第三控制点P4的位置坐标P4=(X4,Y4),第三终止点P5的位置坐标P5=(X5,Y5)。在贝塞尔曲线函数中,数值n、权重Wi、位置对应值t及Pi的定义与前述第一实施方式的定义相同,在此不赘述。在定义完第三起始点P3、第三控制点P4及第三终止点P5后,本发明的实施方式进一步界定第三外形曲线B3的限制:X3=X5,Y3≧Y4≧Y5,及0≦Wi≦1。Therein, there is at least one third control point P 4 between the third starting point P 3 and the third ending point P 5 . The third control point P 4 is mainly used to determine the curvature of the third contour curve B3. In addition, when the total number of points of the third control point is 1, the position coordinate P 3 = (X 3 , Y 3 ) of the third starting point P 3 is defined, and the position coordinate P 4 of the third control point P 4 is (X 4 , Y 4), the third termination coordinate point P 5 P 5 = (X 5, Y 5). In the Bezier function, the definitions of the numerical value n, the weight W i , the positional correspondence values t and P i are the same as those of the first embodiment described above, and are not described herein. After defining the third starting point P 3 , the third control point P 4 and the third ending point P 5 , embodiments of the present invention further define a limitation of the third profile curve B3: X 3 =X 5 , Y 3 ≧Y 4 ≧Y 5 , and 0≦W i ≦1.
再次参照图5A至图5D,在第五实施方式中,第一外形曲线B1及第二外形曲线B2是与第三实施方式的相同定义所形成。第三外形曲线B3是以第三起始点P3=(0,21)、第三控制点P4=(10.6,10.6)、第三终止点P5=(0,0)及W4=0.45为参数条件所形成的曲线(如图5C所示)。图5B显示光线由第一端面512进入至导光组件500中,在导光组件500中经反射后,由第二端面
514发射出去。在此实施方式中,经过导光组件500的导引后,出射光所形成的光束角约为13度。藉此,由上述第一实施方式到第五实施方式可知,通过调整第三外形曲线B3的各参数值可改变整个第二端面514的曲面形状。Referring again to FIGS. 5A to 5D, in the fifth embodiment, the first outer shape curve B1 and the second outer shape curve B2 are formed in the same manner as the third embodiment. The third contour curve B3 is a third starting point P 3 = (0, 21), a third control point P 4 = (10.6, 10.6), a third ending point P 5 = (0, 0), and W 4 = 0.45 The curve formed for the parameter conditions (as shown in Figure 5C). FIG. 5B shows that light enters the light guide assembly 500 from the first end face 512 and is reflected by the second end face 514 after being reflected in the light guide assembly 500. In this embodiment, after being guided by the light guiding assembly 500, the beam angle formed by the emitted light is about 13 degrees. Thereby, it can be seen from the above-described first to fifth embodiments that the curved shape of the entire second end surface 514 can be changed by adjusting the respective parameter values of the third outer shape curve B3.

In this embodiment, light directing assembly 800 also has a first end surface 812, a second end surface 814, an outer surface 816, and an inner surface 818. The outer surface 816 is formed by twelve first reflective curved surfaces, and the first reflective curved surfaces are also constructed by the first outer shape curve B1. Similarly, the inner surface 818 is formed by twelve second reflective curved surfaces, which are also constructed with a second contour curve B2.
由上述可知,导光组件600、700、800可变化成各种不同的形状,同样可改变进入导光组件600、700、800中的光线的光束角。更具体地,在第六实施方式中的第一反射曲面及第二反射曲

是入光面,此方式不同于前述第一实施方式(如图1A及1B所示),第一端面112的全部表面皆作为入光面,因此,有关入光面的方式并不局限于本发明所记载的实施方式。In the present invention, the aforementioned light guiding components may have different designs. 11A and 11B, which are respectively a perspective view and a cross-sectional view showing a light guiding assembly according to a seventh embodiment of the present invention. The light guiding assembly 900 of the present embodiment includes a first end surface 910, a second end surface 920, an outer surface 930, and an inner surface 940. The first end surface 910 has a first outer peripheral edge 910a and a first inner peripheral edge 910b. The second end surface 920 is opposite to the first end surface 910, and the second end surface 920 has a second outer circumference 920a and a second inner circumference 920b. In this embodiment, the second end surface 920 of the light guiding component 900 can be a light emitting surface, and the first end surface 910 of the light guiding component 900 is recessed inward to form an annular groove 911. The annular groove 911 can be mainly used. The light source in the luminaire is accommodated, and therefore, the inner surface of the annular groove 911 is
It is a light incident surface. This method is different from the first embodiment described above (as shown in FIGS. 1A and 1B ). The entire surface of the first end surface 112 serves as a light incident surface. Therefore, the manner of the light incident surface is not limited to this. The embodiment described in the invention.
如图11A及图11B所示,外表面930连接第一外周缘910a与第二外周缘920a,且内表面940连接第一内周缘910b与第二内周缘920b。因此,内表面940a紧邻第一内周缘910a的地方可定义为第一开口901a,且此第一开口901a位于第一端面910上。同样地,内表面940a紧邻第二内周缘920b的地方可定义为第二开口901b,且此第二开口901b位于第二端面920上。其中,第一开口901a与第二开口901b互相连通,且第一开口901a的面积大于第二开口901b的面积。也就是说,第一端面910的面积小于第二端面920的面积。在实施例中,第一开口901a的直径大于第二开口901b的直径。As shown in FIGS. 11A and 11B, the outer surface 930 connects the first outer peripheral edge 910a and the second outer peripheral edge 920a, and the inner surface 940 connects the first inner peripheral edge 910b and the second inner peripheral edge 920b. Therefore, the portion of the inner surface 940a adjacent to the first inner circumference 910a may be defined as the first opening 901a, and the first opening 901a is located on the first end surface 910. Similarly, a portion of the inner surface 940a adjacent to the second inner circumference 920b may be defined as a second opening 901b, and this second opening 901b is located on the second end surface 920. The first opening 901a and the second opening 901b communicate with each other, and the area of the first opening 901a is larger than the area of the second opening 901b. That is, the area of the first end surface 910 is smaller than the area of the second end surface 920. In an embodiment, the diameter of the first opening 901a is greater than the diameter of the second opening 901b.
再次参照图11A及图11B,导光组件900具有第一区段S1以及第二区段S2。第一区段S1具有曲率。也就是说,导光组件900的内表面930及/或外表面940位于第一区段S1的部分可为环状曲面。在实施例中,此环状曲面亦可由前述实施例所述的外型曲线所定义。此外,第二区段S2不具有曲率。也就是说,导光组件900的内表面930与外表面940位于第二区段S2的部分均为环状平面。如图11A及图11B所示,第二区段S2较第一区段S1凸出,藉此可使外表面930位于第二区段S2的直径大于外表面930位于第一区段S1的直径。Referring again to FIGS. 11A and 11B, the light guide assembly 900 has a first section S1 and a second section S2. The first section S1 has a curvature. That is, the portion of the inner surface 930 and/or the outer surface 940 of the light guiding component 900 that is located in the first section S1 may be an annular curved surface. In an embodiment, the annular curved surface may also be defined by the profile shown in the previous embodiments. Furthermore, the second section S2 does not have a curvature. That is to say, the portions of the inner surface 930 of the light guiding assembly 900 and the outer surface 940 located at the second section S2 are both annular planes. As shown in FIGS. 11A and 11B, the second section S2 protrudes from the first section S1, whereby the diameter of the outer surface 930 at the second section S2 can be made larger than the diameter of the outer surface 930 at the first section S1. .
另参照图12A至图12B,其中,图12A是示出根据本发明一实施方式的一种灯具的分解示意图,图12B是示出根据本发明一实施方式的一种导光组件卡合于托座上的剖面示意图,以及图12C是示出根据本发明实施方式的一种灯具的剖面示意图。本实施方式的灯具960包括基座961、光源963以及前述的导光900组件。光源963结合在基座961上。导光组件900可拆卸地结合于基座961。其中,当导光组件900在第一位置时,能够从基座
961分离。当导光组件900在第二位置时,则是结合于基座961。12A to 12B, wherein FIG. 12A is an exploded perspective view showing a light fixture according to an embodiment of the present invention, and FIG. 12B is a view showing a light guide assembly engaged with the light guide according to an embodiment of the present invention. A schematic cross-sectional view of the seat, and FIG. 12C is a schematic cross-sectional view showing a luminaire according to an embodiment of the present invention. The light fixture 960 of the present embodiment includes a base 961, a light source 963, and the aforementioned light guide 900 assembly. Light source 963 is coupled to base 961. The light guide assembly 900 is detachably coupled to the base 961. Wherein, when the light guiding component 900 is in the first position, it can be from the base
961 separation. When the light guiding component 900 is in the second position, it is coupled to the base 961.
在实施例中,基座961包括座体961a以及设置在座体961a上的托座961b,并可同时将光源963固定座体961a上。在一例子中,托座961b可通过螺丝锁设于座体961a上。如图12A所示,光源963包括电路板963a以及复数个设置在电路板963a上的发光二极管963b。其中,电路板963a具有第一接合部963c。托座961b的底部具有对应电路板963a的第一接合部963c的第二接合部965a。藉此,当托座961b将光源963固定在座体961a上时,电路板963a的第一接合部963c位于托座961b的第二接合部965a中,且可第二接合部965a可限位电路板963a的第一接合部963c。In the embodiment, the base 961 includes a seat body 961a and a bracket 961b disposed on the seat body 961a, and the light source 963 can be simultaneously fixed to the seat body 961a. In an example, the bracket 961b can be locked to the seat body 961a by screws. As shown in FIG. 12A, the light source 963 includes a circuit board 963a and a plurality of light emitting diodes 963b disposed on the circuit board 963a. Among them, the circuit board 963a has a first joint portion 963c. The bottom of the bracket 961b has a second engaging portion 965a corresponding to the first engaging portion 963c of the circuit board 963a. Thereby, when the bracket 961b fixes the light source 963 on the base 961a, the first engaging portion 963c of the circuit board 963a is located in the second engaging portion 965a of the bracket 961b, and the second engaging portion 965a can limit the circuit board The first joint portion 963c of 963a.
再次参照图12A至图12B,托座961b具有对位区965b以及邻设于对位区965b的挡缘965c。其中,对位区965b可定义为第一位置。如图12B所示,当托座961b固定在座体961a上时,挡缘965c与座体961a之间可形成定位区965d。其中,定位区965d连通对位区965b,且定位区965d可定义为第二位置。此外,导光组件900包括有邻设于第一端面910的结合部950。Referring again to FIGS. 12A-12B, the bracket 961b has a registration area 965b and a rim 965c adjacent to the alignment area 965b. Wherein, the alignment area 965b can be defined as the first location. As shown in FIG. 12B, when the bracket 961b is fixed to the seat body 961a, a positioning area 965d can be formed between the flange 965c and the seat body 961a. The positioning area 965d is connected to the alignment area 965b, and the positioning area 965d can be defined as the second position. In addition, the light guiding component 900 includes a bonding portion 950 adjacent to the first end surface 910.
藉此,在将导光组件900组装置座体961a时,可先沿着第一方向D1移动导光组件900至第一位置,也就是使导光组件900的结合部950对应置入托座961b的对位区965b中。接着再沿着第二方向D2旋转导光组件900,以使导光组件900旋转至第二位置,也就是使导光组件900的结合部950移动至定位区965d中并与托座961b的对位区965b形成错位,进而可使导光组件900卡设在托座961b上。此时,托座961b的挡缘965c可限位导光组件900的结合部950,进而达到固定导光组件900的目的。进一步而言,当导光组件900位于第一位置时,结合部950位于对位区965b中,而当导光组件900位于第二位置时,
结合部950则位于定位区965d中。如图12C所示,当导光组件900卡合于托座961b上时,发光二极管963c位于导光组件900的环状沟槽911中,进而可将光线从导光组件900的环状沟槽911内表面射入导光组件900中。Therefore, when the light guide assembly 900 is assembled to the base 961a, the light guide assembly 900 can be moved to the first position along the first direction D1, that is, the joint portion 950 of the light guide assembly 900 is correspondingly placed in the bracket. 961b in the alignment area 965b. Then, the light guide assembly 900 is rotated along the second direction D2 to rotate the light guide assembly 900 to the second position, that is, the joint portion 950 of the light guide assembly 900 is moved into the positioning region 965d and the pair with the bracket 961b. The bit region 965b is misaligned, thereby allowing the light guiding member 900 to be snapped onto the bracket 961b. At this time, the retaining edge 965c of the bracket 961b can limit the joint portion 950 of the light guiding assembly 900, thereby achieving the purpose of fixing the light guiding assembly 900. Further, when the light guiding component 900 is in the first position, the bonding portion 950 is located in the alignment area 965b, and when the light guiding component 900 is in the second position,
The joint portion 950 is located in the positioning area 965d. As shown in FIG. 12C, when the light guide assembly 900 is engaged with the bracket 961b, the LED 963c is located in the annular groove 911 of the light guide assembly 900, thereby allowing light to pass from the annular groove of the light guide assembly 900. The inner surface of the 911 is incident on the light guide assembly 900.
由上述本发明实施方式可知,本发明的优点是通过第一外形曲线、第二外形曲线以及第三外形曲线来改变外表面、内表面以及第二端面的曲面形状,利用光的全反射特性以控制光的行进方向,来调整导光组件所输出的光型,以符合各种灯光角度照射需求,同时可减少能量损耗。此外,本发明通过贝塞尔曲线来定义各个外形曲线,不但简化了各曲面的定义规则,并且可以更直觉的方式控制整个外形曲线的形状。It can be seen from the above embodiments of the present invention that the present invention has the advantages of changing the curved shapes of the outer surface, the inner surface, and the second end surface by using the first outer shape curve, the second outer shape curve, and the third outer shape curve, and utilizing the total reflection characteristic of light to The direction of travel of the light is controlled to adjust the light output of the light guide assembly to meet various lighting angle illumination requirements while reducing energy loss. In addition, the present invention defines each shape curve by a Bezier curve, which not only simplifies the definition rules of each surface, but also controls the shape of the entire profile curve in a more intuitive manner.
虽然本发明已以实施方式揭露如上,然其并非用以限定本发明,任何本领域的技术人员在不脱离本发明的精神和范围内,当可作各种的更动与润饰,因此本发明的保护范围当以权利要求所界定的范围为准。The present invention has been disclosed in the above embodiments, but it is not intended to limit the present invention, and the present invention can be variously modified and retouched without departing from the spirit and scope of the present invention. The scope of protection is subject to the scope defined by the claims.
