背景技术 Background technique

这样的LED照明模块例如应用在手电筒中。 Such an LED lighting module, such as used in flashlights. 按现有技术已知的配备白炽灯的手电筒目前具有一个朝端面锥形地变宽的灯头,在其内部设置一个大多数情况下构成为抛物线的凹面反射镜,在凹面反射镜的焦点上设置白炽灯或其螺旋形灯丝。 Known according to the prior art incandescent flashlight with a current having conically widening towards the end face of the base, is provided in the interior configured to parabolic concave mirror, disposed at the focus of a concave mirror in most cases or incandescent helical filament. 通过这种布置应该保真最佳的光线效率。 By this arrangement should fidelity optimum light efficiency. 这样的凹面反射镜面可能不利地容易污染或者镜表面通过腐蚀效应而可能退色,使得光线的反射变得较弱。 Such a concave mirror may adversely easily contaminated by etching or mirror surfaces may fade effect, so that the reflected light becomes weaker.

在较早的时期配备发光二极管的手电筒推上市场。 At an early period with LED flashlight onto the market. 发光二极管明显比白炽灯消耗更少的电并且大多数情况下可以用较低的工作电压进行工作,使得小的电池体(小型电池)作为电源就足够了。 Light-emitting diode consumes significantly less power than incandescent lamps and can be operated at a lower operating voltage in most cases, so that a small cell body (small battery) as a power supply is sufficient. 特别是通过采用发光二极管可以制造结构方式较小的手电筒,使得它们可以作为钥匙挂件等方便地一起携带。 In particular by using a light emitting diode structure can be fabricated smaller flashlight manner such that they can be used as a key fob and other easily carried together. 除了较小的耗电之外,已经得到证实的是,发光二极管由于结构原因也特别是对于冲击和击打不敏感的。 In addition to small power consumption, it has been confirmed that the light emitting diode due to structural reasons and especially for the impact striking insensitive. 另外发光二极管具有极长的寿命,因此取消在较早时期经常必需的白炽灯更换。 Additionally, the LEDs have an extremely long life, and therefore cancel earlier by replacing incandescent often required. 既使在发光二极管作为光源的情况下,给定的光线发射也应最佳地利用。 Even in the case of a light emitting diode as a light source, the light emission given should be optimally utilized. 部分在灯中能发现的反射镜的原则上可能的应用具有上述缺点。 Possible applications having the above drawbacks in principle, can be found in the lamp portion of the mirror. 另外期望该构件也能省去。 Further desirable that the member can be omitted.

在一些由现有技术已知的手电筒中,在光线射出面上设置一个聚光透镜,它在使光线发射的位置设置于该聚光透镜的焦点上的情况下基本上可以射出平行的光束。 In some prior art known by the flashlight, is provided on a light exit surface of the condenser lens, the light rays emitted at that location is provided in the case where the focal point of the condenser lens can be substantially parallel to the emitted beam. 在一种进一步发展中,也建议一种沿轴向可移动的灯头,它允许改变聚光透镜相对于LED的位置。 In a further development, also suggests an axially movable cap, which allows a condensing lens to change the relative position of the LED. 因此可以在一定的 So can certain

4界限内改变光束特性。 4 limits the beam characteristics change. 但是这种结构形式仅能使用在这样的发光二极管中,即其射线已经朝前收束。 However, this structure can be used only in such a light emitting diode, i.e. it has forwardly converging rays. 如果发光二极管也将其重要的一部分光线朝侧面即以相对于其轴线较高的角度发射,那么该光线未利用。 If the light emitting diodes are also an important part of the light toward the side surface that is at a higher angle relative to its axis of emission, then the unused light. 现在的高功率发光二极管目前这样构成,使得射线在相对于轴线的大角度范围内出来。 High power light emitting diodes are now present in such a way that the rays over a wide angular range with respect to the axis of the out. 对于这样的发光二极管,辅助光学系统是有意义的。 For such light-emitting diodes, the secondary optical system is significant.

LED灯座的环形面在此平整地贴靠在透镜体的相应环形面上,在此LED的光线发射点这样设置成位置固定的,使得在光学轴线范围内朝口径方向发出的光线应通过准直效应折射成一个平行的光线束。 The annular surface of the LED lamp holder of this flat surface abuts a respective annular lens body, this LED light emission points arranged such fixed into position, so that the light emitted from the optical axis in the diameter direction toward the range to be quasi direct effect into a parallel light rays refracted beam. 在相对于光学轴线较大角度下发出的光线在越过所谓的临界角的时候完全反射并且根据表面曲率以及由此产生的反射角而发生偏转。 With respect to light emitted at large angles to the optical axis is totally reflected at the time of crossing the so-called critical angle and is deflected according to the surface curvature and the angle of reflection therefrom. 在一种这样的例如由US 6,478,453 B2或US 6,547,423 B2已知的辅助光学系统中,确定灯的照射特性。 In one such example, from US 6,478,453 B2 or US 6,547,423 B2 known secondary optical system, determining the irradiation characteristics of the lamp.

发明内容 SUMMARY

本发明的目的是进一步改进一种由LED以及辅助光学系统构成的照明模块。 Object of the present invention is to further improve an illumination module constructed by a LED, and a secondary optical system.

上述目的通过一种LED照明模块解决,其包括一个发光二极管以及一个旋转对称的单件式的透光的辅助光学系统,该辅助光学系统具有一个里面的聚光透镜部分和一个外面的反射镜部分以及一个背面的盲孔形的开口,该开口通过一个锥形的或横截面为弧形的圆锥形的圆周面和一个凸形弯曲的基面限定并且该开口具有一个允许LED体在该开口内沿着辅助光学系统的光学轴线轴向移动的圆周直径,其中聚光透镜部分通过作为光线射入面的凸形弯曲的基面和一个前侧的同样凸形地弯曲的光线射出面构成,并且反射镜部分基本上通过开口的作为光线射入面的圆周面、 一个作为光线完全反射面的外面的外壳式的圆周面和一个前面的锥形的光线射出面构成,其中所有光线射入和光线射出面使倾斜出现的光线这样折射,使得由LED射出的光线高于85%地朝前射出并且通过 The above object is achieved by an LED lighting module solutions, which comprises a light emitting diode and a one-piece light-transmitting optical system of a secondary rotational symmetry, the secondary optical system has a lens part converging inside and outside of a mirror portion and a back surface of the blind hole-shaped opening that is defined by a tapered or arc-shaped cross section and a conical circumferential surface of the convex curved base surface and the opening has an opening allowing the inner body LED circular diameter axially movable along the secondary optical system of the optical axis, similarly convexly curved portion of the light through the condenser lens as a convex curved light entrance surface of the base surface and the exit surface of a front side configuration, and mirror sections substantially through the circumferential surface of the opening as the light entrance surface, the light cone and shell and a circumferential surface of the outer front surface totally reflecting a light exit surface is formed as, and in which all rays incident light so that the light emitting surface is inclined such refraction occurs, so that the light emitted by the LED is emitted toward the front than 85% and by — LED的沿轴向的移动可以产生锥角<12°直至锥角>20°的光锥的光锥变化,并且在至少一个相对于辅助光学系统的开口的LED位置上在横截面上垂直于光学轴线均匀地照明一个里面的光锥区域,锥形开口的最小直径> 9mm。 - axially moving the LED may produce a cone angle <12 ° cone angle until> change in the light cone of the light cone of 20 °, and in cross section perpendicular to the at least one position of the LED relative to the auxiliary opening in the optical system the optical axis of a uniformly illuminated region inside the light cone, the smallest diameter of the tapered opening> 9mm.

旋转对称的单件式的透光的辅助光学系统具有一个里面的聚光透镜部分和一个外面的反射镜部分以及一个背面的盲孔状的开口,该开口通过一个锥形的或横截面为弧形的圆锥形的圆周面(Mantelfliiche )和一个凸形弯曲的基面限定并且该开口具有一个允许LED体在该开口内沿着辅助透镜的光学轴线轴向移动的圆周直径。 One-piece light-transmitting optical system rotationally symmetric auxiliary converging lens part has an inside and outside of a mirror portion and a back surface of the blind hole-like opening which through a conical cross-section or an arc conical shaped circumferential surface (Mantelfliiche) and a convexly curved base surface defining the opening and having a circumferential diameter allows the LED body axially movable along the optical axis of the auxiliary lens within the opening. 此下认为,由LED玻璃体以及灯座构成的整个结构在盲孔状开口内的轴向移动是可能的,^:得通过LED相对于盲孔状开口沿着光学轴线的相对运动能变化地调节具有光线射束的不同锥角的不同照射特性。 Under this view that the entire structure of an LED lamp holder constituting the vitreous and axial movement within the blind hole-like opening is possible, ^: can be varied by adjusting the obtained LED blind hole-like opening with respect to the relative movement along an optical axis, irradiating light beam having different characteristics in different cone angles.

聚光透镜具有一个作为光线射入面的凸形弯曲的基面和一个前侧的同样地凸形弯曲的光线射出面。 A condenser lens having a convex light incident surface is a curved base surface and the front side in the same manner convexly curved light exit surface. 在单件式辅助光学系统的范围内在外面直接连接的反射镜部分基本上通过作为光线射入面的盲孔状开口的圆周面、 一个作为光线完全反射面的外面的外壳式的圆周面和一个前面的锥形的光线射出面构成。 The mirror portion out of the range of one-piece inner secondary optical system is substantially directly connected to the circumferential surface by a light entrance surface of the blind hole-like openings, as a shell as the outer circumferential surface of the totally reflecting surface and a light tapered front light exit surface configuration. 所有光线射入面和光线射出面使得倾斜出现的光线这样折射,使得由LED射出的光线基本上完全、尤其是高于85%地朝前射出并且通过整个LED的沿轴向的移动可以产生锥角《12。 All the light entrance surface and light exit surface is inclined so that the light refraction occurs such that the light emitted by the LED is essentially completely, in particular higher than 85% and may be emitted toward the front cone generated by moving the entire axial direction of the LED angle "12. 直至锥角>20°的光锥的光锥变化。 Until cone angle> change in the light cone of 20 ° cone of light. 在至少一个相对于辅助光学系统的盲孔状开口的LED相对位置上在横截面上垂直于光学轴线可以均匀地照明一个里面的光锥区域,优选这样照明,使得在2.5m距离处均匀地照明一个直径为0.80m的圆。 The relative position of the LED relative to at least one blind hole-like opening of the secondary optical system on the cross section perpendicular to the optical axis can uniformly illuminate a region inside the light cone, preferably so that the illumination, so that uniform illumination at a distance of 2.5m a circle with a diameter of 0.80m. 因为重要的仅是LED相对于辅助光学系统的相对移动, 所以该目的可以在LED固定装配的情况下通过可沿轴向移动的辅助光学系统或者在辅助光学系统固定装配的情况下通过可沿轴向移动的LED 或者通过辅助光学系统以及LED的组合移动来实现。 Because the LED is only important that the relative movement of the secondary optical system, so that the object can be axially moved by the secondary optical system along in the case of an LED or fixedly mounted in a case where the secondary optical system can be fixedly mounted by axial or an LED is achieved by moving the secondary optical system, and a combination of movement of the LED.

优选这样的方案,即辅助光学系统设置在一个相对于通常的灯体可沿轴向移动的灯头中,LED也固定安装在该灯体内。 Such a preferred embodiment, i.e., the secondary optical system is usually provided with respect to a lamp body axially movable in the base, LED lamp is also fixedly mounted on the body. 必要时可以为此设置一个沿轴向的或者螺旋形的导向装置。 It can be provided for this purpose a guide means or spiral in the axial direction, if necessary.

原则上按现有技术已知LED相应从透镜体的焦点或从焦点平面朝两个方向的移动,因此得到窄的或宽的照射,也就是说具有较小或较大直径的光线射束。 According to the prior art known in principle from the corresponding LED or the focus of the lens body from moving towards the focal plane of the two directions, thereby obtaining narrow or broad irradiation, i.e. light having a beam diameter smaller or larger. 但是至今主要追求,产生各光线的尽可能平行光束的光线射束。 But so far the main pursuit, parallel beam of light to produce as much as possible each light beam. 但是在所追求的严格的光线的平行性中,在采用点式光源的 However, in pursuit of strict parallelism of light, the point light source is employed

情况下照明的区域受辅助光学系统直径的限制。 Illuminated region in the case of the optical system is limited by the diameter of the secondary. 虽然LED从焦点平面的移动导致光锥的扩展,但是随着离开光学轴线的距离的增长,光强沿径向朝外递减。 Although the LED light cone leads extended from the focal plane of movement, but with the growth of the distance away from an optical axis of the light intensity decreasing radially outward. 通过辅助光学系统按菲涅耳透镜的形式构成有一个聚光透镜部分以及一个反射镜部分,可以按这种方式组合聚光透镜的准直特性和外面的辅助光学系统部分的反射特性,使得汇聚的以及发散的光线在发光二极管相对于辅助光学系统的确定位置上照明一个均匀的面,尤其是在2.5m距离处直径为80cm。 By constituting the secondary optical system in the form of a Fresnel lens and a converging lens part reflecting mirror portion, a collimator lens converging characteristics may be combined in this manner and the secondary optical system, a reflection characteristic of the outer portion, such that the convergence and a divergent illumination light uniform surface for determining the position of the secondary optical system on the light emitting diode phase, especially at a distance of 2.5m diameter 80cm.

折射光线或者完全反射光线的表面可以借助于二维的尺寸切割方法(2D-MaBschndderverfahren )进行计算。 Or the surface refracted ray is totally reflected light can be calculated by means of the two-dimensional size of the cutting method (2D-MaBschndderverfahren).

因此反射镜部分的光线射出面相对于一个垂直于光学轴线的垂面设置的倾角选择为35°与40。 Thus the light emitted from the mirror section planes relative to a selected vertical plane disposed perpendicular to the optical axis of 35 ° and 40. 之间优选37。 Preferably between 37. . 锥形开口的最小直径应为最小9mm,因此允许所有常用的发光二极管包括灯座可在该开口内沿轴向移动,使得LED连同灯座一起可以推入到后面的开口内。 The minimum diameter of the tapered opening should be minimized 9mm, thus allowing the light emitting diode includes all common socket is axially movable within the opening, such that the LED together with the socket can be pushed into the back of the opening. 辅助光学系统的总高度应该在9mm与16mm之间,这通过一个聚光透镜部分与一个外面的反射镜部分的组合是可能的。 The total height of the secondary optical system should be between 9mm and 16mm, that by combining a condenser lens portion and an outer portion of the mirror is possible. 优选聚光透镜部分的内径比辅助光学系统的开口的最大直径最多大lmm。 Preferably the inner diameter of the condenser lens portion than the maximum diameter of the opening up to the secondary optical system is large lmm.

按本发明的另一结构,反射镜部分可以具有外面的边缘表面段,它们设置成平行于辅助光学系统的光学轴线。 According to another structure of the present invention, the mirror portion may have an outer edge surface sections, which are arranged parallel to the secondary optical system of the optical axis. 因此保证散光在边缘区域内的存在。 This ensures astigmatism exists in the edge region.

另外反射镜部分可以具有环形面段,它们设置成环绕开口并且垂直于光学轴线和/或设置成在前侧外面并且垂直于光学轴线。 Further the mirror portion may have an annular surface section, which are arranged to surround the opening and perpendicular to the optical axis and / or arranged outside of the front side and is perpendicular to the optical axis. 里面的聚光透镜的厚度相对于辅助光学系统的高度的比例优选在0.6与0.65之间,优选为0.614。 Thickness of the rear condenser lens with respect to the ratio of the height of the secondary optical system is preferably between 0.6 and 0.65, preferably 0.614. 最后里面的聚光透镜部分具有一个光线射出面,其曲率半径小于光线射入面的曲率半径。 Inside the final part of the condenser lens having a light exit surface, a curvature radius smaller than the radius of curvature of the light entrance surface. 按本发明聚光透镜部分具有一个至少40。 According to the present invention, the converging lens part has an at least 40. 优选42。 Preferably 42. 的开口角。 Opening angle.
