作为常规照明设备,使用诸如荧光灯、白炽灯以及聚光灯的各种类型的照明光源。 As a conventional lighting equipment, various types of illumination sources such as a fluorescent lamp, incandescent lamp and a spotlight. 但是,来自这种照明光源的照明光包括损坏被照射目标的紫外线,或该照明光源由于热量的产生,具有安装限制。 However, this illumination light from the illumination light source comprises ultraviolet radiation damage to the target, the illumination source, or due to generation of heat, a mounting restrictions. 考虑到诸如C02减小的环境问题,希望光源具有尽可能小的功耗。 For environmental reasons, such as C02 is reduced, it is desirable to have as small a power source. 最近,一种产生少量热量和具有小功耗的LED光源引起相当大的关注,以及还提供一种具有高亮度的白光LED。 Recently, a small amount of heat is generated and the LED light source having a small power consumption caused considerable concern, and further to provide a high brightness white LED. 因此,普通照明设备中的LED光源的用途被增加。 Thus, the use of general lighting LED light source is increased. 由于LED具有高亮度和高发热值,对于功耗是适合的。 Since the LED having high luminance and high calorific value, are suitable for consumption. 但是, 由于LED不包括紫外线或红外线,因此它几乎不损坏被照射的目标。 However, since not including ultraviolet or infrared LED, it almost does not damage the target is irradiated. 在JP-A-2000-021209中公开了这类照明设备的例子。 In JP-A-2000-021209 discloses an example of such an illumination device.

发明内容 SUMMARY

本发明解决的问题 The invention solves the problem

但是,即使该LED具有高方向性,但是由该LED获得的直射光的照明度分布随着照射距离增加而变宽。 However, even if the LED has high directivity, but the direct illumination light obtained by the LED illumination distribution with increasing distance widened. 此外,因为照射区被过分地加大,照明度变得不充足。 Further, since the irradiation region is increased excessively, the illuminance becomes insufficient. 图34A示出了当作为单体发光的LED81没有设有反射面时,在预定距离处的表面上的照明度分布。 FIG 34A shows a light emission when LED81 as a monomer with no reflecting surface, illuminance on the surface profile at a predetermined distance. 当在预定距离处, 作为单体的LED 81在表面上发光时,在低亮度下获得宽的光分布,如图34A所示。 When the predetermined distance, as the LED 81 emitting the monomer on the surface, to obtain a wide distribution of light at low luminance, as shown in FIG 34A. 因此,已经提出了在LED光源中设置反射面的结构。 Thus, it has been proposed to provide a reflective surface of the LED light source structure. 但是, 尽管反射面将指向LED光源的侧面或背面的光返回前侧,但是很难说反射面具有优异的光聚焦特性。 However, although the light reflection surface directed to the side or back of the front side of the LED light source is returned, it is difficult to say a light reflecting surface having excellent focusing characteristics. 此外,照明度分布也可以被变宽,以及不必要的区域可能被照射。 Further, the illuminance distribution may also be widened, and the unnecessary area may be illuminated. 因为这种环境,具有高亮度的光源用来获得需要的和足够的照明度。 Because of this environment, the light source having high brightness and sufficient to obtain the desired degree of illumination. 为了限制将被照射的区域,通过光屏蔽部件如百叶窗切断不必要的光。 To limit the area to be irradiated by the light shielding member such as a louver cut unnecessary light.

但是,高亮度光源使用大量的电功率,以及其尺寸也是大的。 However, high brightness light source a large amount of electric power, and its size is large. 因此,当安装在照明设备上时,该光源具有许多约束,以及其应用范围被限制。 Thus, when mounted on the illumination device, the light source has a number of constraints, and their application range is limited. 此外,光屏蔽部件如百叶窗可能降低光使用效率,因此仍然留下许多待解决的问题。 Further, the light shielding member such as a louver light use efficiency may be reduced, and therefore still left many problems to be solved.

通常,作为照明光源,需要一种光源,通过该光源在高照明度下 Typically, as a light source, a need for a light source, a high degree of illumination by the light source

获得具有平坦照明度分布的照明区。 Obtained illuminance illuminated area has a flat profile. 如图34B所示,在LED81的侧面(或后侧)中设置具有凹入的抛物线表面的反射板83。 As shown in FIG. 34B, the reflecting plate 83 is provided with a parabolic concave surface of the side surface LED81 (or rear side). 然后,来自LED 81的光被反射板83平行校正(collimate),由此增加光通量密度。 Then, light from the LED 83 is collimated (collimate) 81 of the reflection plate, thereby increasing the flux density. 通过该反射板还可以延伸光的可达到距离。 With the reflection plate may also extend up to a distance of light. 此外,尽管发射到LED 81侧的光分量被反射板83偏转,但是没有照射在反射板83上的光分量86继续前进到光路的前侧,同时被散射。 Further, although the LED 81 emitting the light component is deflected by reflecting side plate 83, but there is no light component impinging on the reflecting plate 83 of the front side 86 proceeds to the optical path while being scattered. 因此,尽管通过反射板83提高照明度的照明度分布,但是仍然示出了宽的分布,在照明需要的高照明度下,没有足够地获得具有平坦照明度分布的照明区。 Therefore, despite the increase in the reflection plate 83 by the illuminance distribution of the illumination, but still shows a broad distribution, at high illumination lighting needs not be obtained sufficiently illuminated area has a flat illuminance distribution. 此外,当LED 81以小的照明角度如10°发光时,从LED81发射的光不被照射在反射板83上,基本上没有被偏转的分量增加,以致不能期望改进照明度。 Further, when the LED 81 at a small angle such as 10 ° emitting illumination light emitted from LED81 is not irradiated onto the reflecting plate 83, the deflection increases substantially no component, so that the illumination can not be expected to improve.

考虑到使用透镜来延伸光的可达到距离。 Considering the use of a lens to extend the distance of the light can be achieved. 但是,布置透镜增加部件的数目,由此增加成本,装配性能被降低,以及需要诸如调整光轴等的额外操作。 However, increasing the number of the lens member is disposed, thereby increasing the cost, assembly performance is lowered, and the need for additional operations such as adjusting an optical axis or the like. 由此,在以低成本实现照明设备中有许多困难。 Thus, there are many difficulties in the illumination device at low cost.

本发明的优点是它提供一种照明单元,通过该照明单元,在高照明度时获得具有恒定平坦照明度分布的照明区,同时节省电功率,以及可以延伸光照射距离,在照明区不产生颜色发暗或阴影,以及提供一种包括该照明单元的照明设备。 Advantage of the invention is that it provides an illumination unit, by the illumination unit, to obtain an illumination region having a constant flat illuminance distribution at high illuminance while saving electric power, and can extend the light irradiation distance, does not produce a color in the illumination region dark or shadow, and there is provided a lighting device comprising the lighting unit.

根据该照明单元,第二反射部件的高度被设为高于从第一反射部件发射的光通量和在第二反射部件上的其阴影之间第一边界线和来自另一相邻的发光二极管的光通量和在第二反射部件上的其阴影之间的第二边界线第一次交叉的点。 According to the illumination unit, the second reflective member is set higher than the height of a boundary line between the first light flux emitted from the first reflecting member and its shadow on the second reflective member and light emitting diode from another adjacent the second boundary line between the light flux and its shadow on the second reflective member of the first intersection point. 然后,当在安排在第二反射部件的表面内的第二反射部件上未照射来自发光二极管的光通量时,产生阴影,没有达到(传播)在超出第二反射部件的发光侧上。 Then, when the second reflective member arranged on the inner surface of the second reflecting member not irradiated with the light flux from the light emitting diode, shadows, does not reach the (spread) beyond the second side of the light emitting member in reflection. 由此,不产生阴影与光通量一起输出时产生的照明光的颜色发暗或阴影。 Thus, no color of the illumination light generated when the light flux output together with the dark shadow or shadows.

如图3所示,背板15包括具有V形截面表面的伞状部件29,在伞状部件29的内表面中布置肋条30,以便支撑布线基板19的背表面,以及在伞状部件29的纵向中的多个位置(在该实施例中,五个)处布置锁钩31,以便与反射体部件23啮合。 3, the back plate 15 having a V-shaped member including an umbrella-sectional surface 29, the ribs 30 disposed within the surface of the shade member 29, so as to support the back surface of the wiring substrate 19, and the umbrella member 29 a plurality of longitudinal positions (in this embodiment, five) of the locking hook 31 is arranged to engage with the reflective member 23. 锁钩31用具有U形截面表面的钩形形成。 Locking hook 31 forming a hook having a U-shaped section of the surface.

布线基板19是,例如,具有成一直线安装的多个(在实施例中, 十六个)LED 17的印刷电路板,以沿反射体部件23的纵向对应于各个抛物面镜25a。 Wiring board 19 is, e.g., mounted in-line with a plurality of (in the embodiment, sixteen) LED printed circuit board 17, the reflector member along the longitudinal direction corresponding to each of the parabolic mirror 25a 23. 引线33从将被连接到驱动单元11的一侧拉出(参考图l)。 Lead 33 is connected to one side from the drive unit 11 is pulled out (refer to FIG.

在反射体部件23中,在长-板形安装基座24的两侧中形成固定照明单元100的支架37,以及在图3中的安装基座524的上和下方向中设置与背板15的锁钩31啮合的啮合部件39。 The reflector member 23, a long - fixing the illumination unit 100, the carriage 37 is formed on both sides of a plate-shaped mounting base 24, and upper and lower direction of the mounting base 524 in FIG. 3 and the back plate 15 is provided in the engaging member 31 engages locking hook 39. 啮合部件39通过锁扣作用与背板 The engaging member 39 by the latching action of the backplane

1515的锁钩31可分离地结合,具有在啮合部件39和背板15之间插入的布线基板19。 1515 shackle 31 is detachably associated, with wiring substrate 19 and the back plate 39 between the engaging member 15 is inserted.

当反射体部件23、布线基板19和背板15互相结合时,在第一反射部件25的抛物面镜的焦点位置中放置LED 17的发光表面。 When the reflective member 23, the wiring substrate 19 and the back plate 15 bonded to each other, the light emitting surface of the LED 17 is placed at the focal position of the first reflecting member 25 of the parabolic mirror. 换句话说, 在反射体部件23中,在布线基板19的表面上邻接表面被分离地布置。 In other words, the reflector member 23, the upper surface of the wiring substrate 19 is disposed adjacent to a surface separately. 形成该邻接表面,以具有在抛物面镜的焦点位置中设置LED 17的发光表面的这种高度。 The abutment surface is formed to have a light emitting surface of LED 17 is disposed at the focal position of the parabolic mirror in such a height. 此外,背板15的肋条30被设为具有当在反射体部件23中形成的基板存储位置中安排布线基板1卯寸在该邻接表面上按压布线基板19的高度。 Further, the ribs 30 of the back plate 15 is set to have a storage position when the substrate is formed in the reflector member 23 arranged in the wiring board pressed against the wiring substrate 1 d inch in height on the surface 19 of the abutment.

由此,当反射体部件23、布线基板19以及背板15被简单地互相结合时,抛物面镜的焦点位置和LED 17的发光表面的位置互相高精度重合。 Accordingly, when the reflection member 23, a wiring board 19 and the back plate 15 is simply bonded to each other, the focal position of the parabolic mirror and the position of the light emitting surface of the LED 17 coincide with each other with high accuracy. 这种结构允许上面的元件被简单地互相结合,而不使用诸如被使用的螺钉的加固方法。 This structure allows the above elements are simply bonded to each other without using the reinforcing method such as a screw being used. 因此,部件的数目减小和用于装配或的工序数目减小,以便提高生产率。 Thus, the number of parts and a reduced number of steps of the assembly or decreased in order to increase productivity.

接下来,将描述具有这种结构的照明单元100的光学特性。 Next, the optical characteristics of the lighting unit 100 having such a structure will be described.

图4是图2所示的照明单元的剖面图,沿线AA。 FIG 4 is a sectional view of a lighting unit shown in FIG. 2, along line AA.

照明单元100的反射体部件23具有互相连续地形成的第一和第二反射部件25和27。 Illuminating the reflector member 23 having a first unit 100 and second reflective member 25 is formed continuously to each other and 27. 在第一反射部件25的基座端部中,设置一开口41, 其中在抛物面镜25a的焦点位置中布置LED的发光表面。 The base end of the first reflecting member 25, an opening 41 is provided, wherein the light emitting surface of the LED disposed at the focal position of the parabolic mirror 25a. 第一反射部件25的抛物面镜25a具有反射面,该反射面具有抛物线表面,其中焦点位置被设为LED n的发光表面,以及将来自LED 17的光朝着发光侧的方向反射,以便在宽泛的透视图中,基本上被平行校准。 A first reflecting member 25a 25 having a parabolic mirror reflective surface, the reflective surface having a parabolic surface, wherein the focus position is set to the light emitting surface of the n-LED, and the reflected light from the LED 17 toward the light emitting side in order in a wide the perspective view, substantially parallel alignment.

在第一反射部件25的发光侧上设置的第二反射部件27具有相对于抛物面镜25a的布置方向,亦即,相对于LED 17的布置方向平行布置的 A second reflecting member on the light emitting side of the first reflecting member 25 is disposed with respect to the arrangement direction 27 of the parabolic mirror 25a, i.e., arranged in parallel with respect to the arrangement direction of the LED 17

16平板镜27a。 16 flat mirror 27a. 第二反射部件27接收未被照射在第一反射部件25上的来自LED 17的光,以便将该光朝着发光侧的方向反射,以基本上被平行校准。 The second reflecting member 27 is not receiving light from the LED 17 on the first reflecting member 25, so that the reflected light toward the light emitting side to be substantially collimated. 第一反射部件25具有预定的反射表面区M1,以及第二反射部件27 具有连续至反射表面区M1的预定反射表面区M2。 The first reflecting member 25 having a predetermined reflective surface area M1, and the second reflecting member 27 having a continuous reflective surface to the reflective surface region of a predetermined area M1 M2. 因此,在宽泛的透视图中,被第一和第二反射部件25和27反射的光变为将被照射在目标上的大量平行光。 Thus, in broad perspective, the first and second reflective member 25 and the reflected light 27 becomes a plurality of parallel light to be irradiated on the object.

相对于LED 17的光轴,平板镜27a的倾斜角被设为未被照射在第一反射部件25的来自LED 17的光通量被平行校准的角度。 With respect to the optical axis of the LED 17, the mirror plate 27a is set at the angle of the inclination angle is not irradiated with the collimated light flux from the LED 17 in the first reflecting member 25. 在该实施例的情况下,相对于LED的光轴,倾斜角被设在20。 In the case of this embodiment, the optical axis of the LED, the inclination angle is set at 20. 至27°的范围内。 To the range of 27 °.

这里,LED 17具有宽的照明角,如120° 。 Here, LED 17 having a wide illumination angle, such as 120 °. 尽管在所发射光当中朝着侧面发射的光学分量的数目增加,但是该光分量被第一和第二反射部件25和27捕捉,由此有助于平行校正该光。 While increasing the number of optical components in the emitted light which emitted toward the side, but the first and second light components 25 and 27 capture the reflecting member, thereby facilitating the collimated light. 由此,照明度分布可以被进一步均匀。 Thus, the illuminance distribution may be more uniform.

接下来,将描述通过照明单元100的照明度分布 Next, it will be described by way of the illuminance distribution of the illumination unit 100

图5示出了通过照明单元的照明度分布的曲线图。 FIG. 5 shows a graph illustrating illuminance distribution of the illumination unit.

如图5所示,通过将从LED 17直接照射的光分量和通过第一和第二反射部件25和27反射到达的光分量形成的范围W1中的光量大于其他区域,以及其边界清楚地出现。 5, the light amount range W1 formed by light components from the LED 17 is directly irradiated by the light components and the first and second reflecting members 25 and 27 reach the reflection clearly appear in other regions, and the boundary . 这是因为光被聚焦以及在范围W1内光通量基本上被平行校正,以便范围W1变为发射照明度高的状态。 This is because the light is focused, and in the range of W1 substantially parallel light flux corrected range W1 to a state to transmit high illumination.

图6示出了当LED发光时,从发光侧看到的反射体部件的状态的说明性视图。 Figure 6 shows when the LED light emission, an explanatory view of a state seen from the emission side of the reflector member.

如图6所示,LED 17的发光表面17a是LED元件17的中心。 6, the light emitting surface 17a of the LED 17 is the center of the LED elements 17. 发光表面17a将图像投射在第一反射部件25的抛物面镜25a的整个表面上。 Projecting an image onto the light emitting surface 17a over the entire surface 25a of the parabolic mirror 25 of the first reflecting member. 此外,发光表面17a的图像也被投射到第二反射部件27的平板镜27a和27a 上。 Further, the light emitting surface 17a of the image is also projected onto the second reflecting mirror plate member 27a 27 and 27a. 亦即,由于其漫射,仅仅第一反射部件25使得从LED 17直接照射的光分量散布,但是第二反射部件27的平板镜27a使得被散射的光分量被散布,以被偏转,以被平行校正。 That is, due to the diffusion, only the first reflecting member 25 such that the light components scattered from the LED 17 is directly irradiated, the second reflecting mirror 27 of the plate member 27a so that the scattered light components are dispersed so as to be deflected so as to be collimation. 这种作用增加将获得的光通量的发射照明度,以及允许精确地均匀化范围W1内的照明度分布。 This effect of increasing the emission illuminance of the light flux will be obtained, allowing accurate and uniform illuminance distribution within the range W1. 结果, 范围W1的边界被清楚地看到。 The results, W1 range boundaries are clearly visible.

接下来,将描述来自照明单元100的光范围。 Next, description will range from the illumination light unit 100.

图7是根据存在或缺少反射表面或其种类,检查通过实施例中的照明单元光源的发射亮度和距光源的距离之间的关系的概念曲线图。 FIG. 7 is a surface or a presence or absence of the reflective type, check conceptual graph showing the relationship between the brightness of the illumination emitted from the light source unit in the embodiment and from the light source through the embodiment.

当距光源如路灯以长距离设置目标时,或当构成警告灯等等用来通知光源位置的距离时,光的可达到距离决定照明设备的性能。 When the lights from the light source, such as when setting a long distance to the target, or when the configuration from the light source position is used to inform the warning lamp and the like, light can reach distance determines the performance of the illumination device. 例如, 图7示出了距光源的光范围取决于反射表面而变化的情况。 For example, FIG. 7 shows the case where the light from the light source depending on the range of the reflecting surface varies.

如图7所示,通过斜线表示发射亮度的极限范围,其中光源的位置可以被识别。 7, the luminance emitted by hatched limits, wherein the position of the light source can be identified. 当不设置反射体时,超过距离Ln,亮度变得不够。 When the reflector is not provided, exceeds the distance Ln, the luminance becomes insufficient. 当仅仅设置抛物面镜时,在距离Ln处,照明单元具有允许的发射亮度,但是超过距离Lp亮度,变得不够。 When a parabolic mirror is provided only at a distance Ln, the emission luminance of the illumination unit has allowed, but exceeds the distance Lp luminance becomes insufficient. 另一方面,当与本发明一样设置抛物面镜25a和平板镜27a时,直至远离距离Ln和Lp的距离Lpp,该照明设备也具有足够的亮度。 On the other hand, when the present invention is provided as a parabolic mirror 25a and the mirror plate 27a, until the distance away from the Lpp Ln and Lp, the illumination apparatus also has a sufficient brightness. 根据本发明的这种结构通过抛物面镜25a和平板镜27a之间的协同效应可以显著地延伸光范围。 Synergy between the parabolic mirror 25a and the mirror plate 27a may significantly extend the range of the light in accordance with the present invention by such a configuration. 例如,当光源的总通量设为42.81m时,在15cm的距离Ln处,获得1200 1x的亮度,在30cm的距离Lp处获得1000 1x的亮度,以及甚至在30m的距离处获得2 1x的亮度。 For example, when the total flux of the light source to 42.81m, Ln at a distance of 15cm, obtain a luminance of 1200 1x, the luminance obtained at 1000 1x 30cm at a distance Lp, and is obtained even at a distance of 30m 2 1x of brightness.

图8示出了相对光谱分布的相对强度和波形之间的相关性曲线。 Figure 8 shows a correlation between relative intensity and waveform relative spectral distributions.

在相对光谱分布中,在450至480nm的波形区中获得具有高强度的光,以及获得560nm左右波形区中的光。 In a relative spectral distribution, the light having high intensity is obtained in the waveform in the region of 450 to 480nm, around 560nm and the light wave is obtained in the region. 440nm的波形周围的顶点表示从蓝光二极管发射的光,以及560nm的波形周围的宽峰表示从荧光粉发射的光。 Around 440nm vertex waveform representation from a blue LED emitting light around 560nm and a waveform represented by a broad peak light emitted from the phosphor. 此外,由于昆虫优选的365nm至410nm之间的波形区的光未被包括在该光谱分布内,该照明设备200可以实现,其中没有有害昆虫如蛾和蚊子飞行。 Further, since the optical waveform insect region between 365nm to 410nm preferably not included in the spectral distribution, the illumination apparatus 200 may be implemented, in which no harmful insects such as mosquitoes and moths fly.

接下来,将描述第二反射部件的投射高度。 Next, the projection height of the second reflective member will be described.

图9是示出了第二反射部件凸出到发光侧中的高度的剖面图。 FIG 9 is a diagram showing a second reflection member protrudes to the height of the cross-sectional view of the light emitting side. 图10 是示出了通过具有第二反射部件的照明单元照射的表面的示意性视图,其高度被设为图9的HM。 FIG 10 is a schematic view of the surface irradiated by the illumination unit has a second reflecting member which is set to the height HM 9 of FIG. 图11A是示意地示出了本发明的照射光的说明性视图,以及图11B和11C是示意地示出了比较例子的照射光的说明性视图。 11A is a schematic explanatory view showing a light irradiation of the present invention, and FIGS. 11B and 11C are a schematic explanatory view showing a comparative example of the irradiation light.

由此,在照明单元100中,第二反射部件27凸出到发光侧面中的高度HM被定义为预定高度。 Accordingly, in the lighting unit 100, a second reflecting member 27 protrudes to the height HM of the light emitting side is defined as a predetermined height. 亦即,当来自LED 17的光通量和在第二反射部件27的表面(平板镜27a)上的其阴影之间的边界线被设为第一边界线45,该来自LED 17的光通量从第一反射部件25发射,以及来自邻近于LED 17的其它LED 17的光通量和第二反射部件27的表面(平板镜27a)上的其阴影之间的边界线被设为第二边界线47时,第二反射部件27凸出到发光侧中的高度HM被设为大于第一边界线45和第二边界线47 第一次交叉的第二反射部件27上的点49的高度Hs,如图9所示。 That is, when the boundary line between the light flux from the LED 17 and its shadow on the reflecting surface of the second member 27 (flat mirrors 27a) is set a first boundary line 45, the light flux from the LED 17 from the first transmitting the reflecting member 25, and from the other surface adjacent to the LED and a second LED 17, the light flux reflecting member 17 27 (flat mirrors 27a) on the boundary line between the shadow which is set to the second boundary line 47, two reflecting member 27 projecting to the light emitting side in a height Hs is set to the height HM of the point 49 on the second reflecting member 27 is greater than the first boundary line 45 and the second boundary line intersecting the first 47, FIG. 9 shows.

换句话说,第二反射部件27凸出到发光侧中的高度HM被设为在第二反射部件27中产生的阴影51可以被保持,而不到达超出第二反射部件27的发光侧上的高度,如图10所示。 In other words, the second reflecting member 27 projecting to the light emitting side is set to the height HM shadow 51 generated in the second reflecting member 27 may be held without reaching beyond the light emitting side of the second reflecting member 27 height, as shown in FIG. 当来自LED 17的光通量不照射在第二反射部件27上时,产生阴影51,来自LED 17的光通量从第一反射部件25发射。 When the light flux from the LED 17 is not irradiated onto the second reflecting member 27, a shadow 51, the light flux emitted from the LED 17 is reflected from the first member 25.

如图11A所示,第二反射部件27的高度HM被定义为这种值。 11A, the height HM of the second reflecting member 27 is defined as such a value. 当来自LED 17的光通量不照射在第二反射部件27时,在第二反射部件27上产生的阴影51安排在第二反射部件27的表面内,不在超出第二反射部件27的发光侧上传播。 When the light flux from the LED 17 is not illuminated when the second reflecting member 27, a shadow generated on the second reflective member 2751 arranged on the inner surface of the second reflecting member 27, does not spread beyond the upper side of the second reflective light emitting member 27 . 因此,使得光不均匀分布的阴影51的影响被减小,以及获得具有高质量的均匀照明光。 Thus, the influence of light unevenly distributed such that the shadow 51 is reduced, and to obtain uniform illumination light having high quality.

另一方面,当第二反射部件的高度HM偏离上面限定的范围时,如 On the other hand, when the height HM of the second reflecting member deviates from the above defined range, such as

图11B所示,或第二反射部件不存在时,如图11C所示,阴影51与光通量53—起输出,以致产生照明光的色彩发暗或网状阴影51a。 As shown in 11B, the absence or the second reflecting member, as shown in FIG, 51 hatched from 53- luminous flux output. 11C, so as to produce color illumination light or dark crosshatched 51a. 结果,照明光变得不均匀。 As a result, the illumination light becomes uniform.

如上所述,根据该实施例的照明单元100和包括该照明单元的照明设备200,第一反射部件25将来自LED 17的光通量朝着发光侧的方向反射,以被基本上平行校正,以及第二反射部件27将不入射在第一反射部件25上的来自LED 17的光通量朝着发光侧的方向反射,以被基本上平行校正,以便照明度分布变得均匀。 As described above, according to this embodiment of the illumination unit 100 and the illumination device comprises an illumination unit 200, a first reflecting member 25 from the LED light flux 17 reflected toward the light emitting side, so as to be substantially parallel to the correction, and the second two reflective member 27 will not be incident on the first reflecting member 25 of the light flux from the LED 17 toward the emission side of the reflector so as to be substantially parallel corrected, so that the illuminance distribution becomes uniform. 此外,由于发射照明度是高的, 光的照射距离可以延伸。 Further, since the emission illuminance is high, the irradiation distance of the light can be extended. 由于以低价提供用作光源的LED 17,照明设备本身可以以低成本制造。 Since as a light source to provide low-cost LED 17, the lighting device itself can be manufactured at low cost. 由于LED使用比白炽灯或荧光灯更少的电源,可以减小日常费用。 Since the LED uses less power than incandescent or fluorescent lamps, running costs can be reduced. 具体地,因为通过第一和第二反射部件25和27提高照明度和照射距离,相同照明度下LED 17的功耗在差不多是霓虹灯的l/6倍以及差不多是荧光灯l/8倍。 Specifically, since 25 and 27 increase the power of the illumination LED 17 and the irradiation distance, the same illuminance by a first and a second reflecting member in almost l / 6 times almost fluorescent and neon l / 8 times. 这种功耗可以提高照明度的能 This power can be improved illumination

量效率,由此有助于减小排出对环境有影响的C02。 The amount of efficiency, thereby contributing to reducing the impact on the environment of discharging C02.

由于在低压下驱动LED 17,在安装之后几乎不发生诸如电击事故的麻烦。 Since the driving LED 17, troubles such as electrical shock hardly occurs at low pressure after installation. 此外,由于基本上不包括紫外光和红外光,不损坏被照射的物体。 Further, since substantially no ultraviolet and infrared light, without damaging the object to be irradiated.

由于照明单元100设有反射体,该反射体包括在LED 17的发光侧上的第一和第二反射部件25和27,因此与在LED 17的背表面中设置反射体的情况相比较,可以使光源单元的厚度小。 Since the illumination unit 100 is provided with a reflector, the reflector comprises a light emitting side of the LED 17 on the first and second reflecting members 25 and 27, and therefore compared with the case of the reflector disposed on the back surface of the LED 17 may be small thickness of the light source unit. 当在诸如其中限制安装空间的陈列橱的位置中存储光源单元时,这些是有利的。 When the light source unit such as a memory wherein space limitations showcase installed position, which is advantageous.

20此外,多个LED 17被排列为一个单元,以构成发光单元21。 20 Further, a plurality of LED 17 are arranged as a unit to constitute the light emitting unit 21. 但是, 如果获得希望的亮度,发光单元21可以仅仅包括一个LED。 However, if a desired brightness, the light emitting unit 21 may include only one LED. 第一反射部件25的抛物面镜25a的反射表面可以不由抛物线表面形成,而是可以由双曲线形成。 A first reflecting surface of the parabolic mirror 25a reflecting member 25 may be formed not by the parabolic surface, but may be formed by a hyperbola. 无论如何,反射表面可以由近似于抛物线表面的曲面形成,以及在抛物线表面中可以总体上形成精巧的平板镜。 In any case, the reflective surface may be formed of parabolic curved surface and a flat mirror may be formed on the whole delicate parabolic surface.

在根据该实施例的照明单元100中,相对于交叉LED 17的LED 17 的布置方向,平行布置第二反射部件对27,如图4所示。 In the illustrated lighting unit 100 according to this embodiment, with respect to the arrangement direction of the LED 17 LED 17 intersect, a second reflecting member arranged in parallel 27, as shown in FIG 4. 由此,通过第二反射部件对27和27中的两个平板镜27a和27a,聚焦从LED 17直接入射在第二反射部件27的光,以便获得高照明度。 Thereby, the second reflecting members 27 and 27 two plates 27a and 27a mirrors, focusing from LED 17 is directly incident on the second light reflecting member 27, so as to obtain a high illuminance.

在设有具有抛物面镜25a的第一反射部件25和具有平板镜27a的第二反射部件27的照明单元100中,第二反射部件27的表面的高度HM被设为高于第一和第二边界线45和47第一次交叉的第二反射部件上的点49。 In a first parabolic mirror having a reflecting member 25a and the second reflecting member 25 having a flat mirror 27a of the illumination unit 27 is 100, the height HM of the second reflective surface of member 27 is set higher than the first and second point 49 on the second reflecting member 45 and the boundary 47 intersects the first time. 因此,当光未照射在第二反射部件27上时,将在第二反射部件27 中产生的阴影51可以被保持,而不到达第二反射部件27上的发光侧, 以及可以防止发生当阴影51与光通量53—起被输出时,产生照明光的色彩发暗或阴影51a。 Thus, when light is not irradiated on a second reflecting member 27, a shadow 51 generated in the second reflecting member 27 may be held without reaching the light emitting side in the second reflecting member 27, and can be prevented when shadows 53- 51 and the light flux from the time of output, the illumination light generated dark color or shading 51a. 结果,可以获得具有高质量的均匀照明光55。 As a result, a high quality can be obtained with uniform illumination light 55.

设有照明单元100的照明设备200包括提供用于驱动LED 17的电功率的驱动单元ll。 Device 100 is provided with the illuminating unit 200 includes a driving unit providing electric power for driving the LED ll 17. 因此,当商用电功率被提供给驱动单元ll时,在高照明度下获得均匀照明度分布,同时节省电功率。 Accordingly, when the commercial electric power is supplied to the drive unit ll, to obtain a uniform illumination distribution in a high illuminance while saving electric power. 此外,通过独立的单个系统可以照射没有任何色彩发暗和阴影的照明光。 Further, a single system can be independent of the color of hair without any illumination of the illumination light and the dark shadow.

第二反射部件27的高度的定义被应用于下面将描述的实施例,可以更可靠地获得均匀照明光。 Define the height of the second reflecting member 27 is applied to the embodiment will be described below, it can be more reliably obtain uniform illumination light.

(第二实施例) 接下来,将描述根据本发明的照明单元的第二实施例。 (Second Embodiment) Next, a second embodiment of the lighting unit according to the present invention will be described. 图12图示了照明单元的透视图,其反射表面由光滑加工表面形成。 FIG 12 illustrates a perspective view of a lighting unit, which reflective surface is formed by a smooth finished surface. 图13是图示了图12所示的反射体部件的剖面图。 FIG 13 is a sectional view illustrating a reflector member 12 shown in FIG. 图14是示出了通过照明单元的照明分布的说明性视图,其反射面由光滑加工表面形成。 FIG 14 is an explanatory view illustrating a lighting unit by the illumination distribution of the reflection surface is formed by a smooth finished surface. 在下面的实施例中,相同参考数字指与图1至6所示的元件相同的元件, 以及其描述将被省略。 In the following embodiments, like reference numerals refer to the same elements as shown in Figures 1 to 6, and description thereof will be omitted.

在根据该实施例的照明单元300中,第一和第二反射部件25和27 的至少一个反射表面(抛物面镜25b和平板镜27b)由光滑加工表面形成。 In the illumination unit 300 according to this embodiment, at least a first and a reflecting surface (parabolic mirror 25b and a flat mirror 27b) and a second reflecting member 25 is formed of a smooth 27 surface in accordance with the processing.

作为第一和第二反射部件25和27的以上反射表面(抛物面镜25b 和平板镜27b)经受的涂敷工序,例示了通过溅射电镀工序的加工。 As above the reflecting surface (parabolic mirror 25b and a flat mirror 27b) of the first and second reflecting members 25 and 27 are subjected to a coating step, exemplified by the sputtering plating processing step. 溅射电镀工序包括使用专用底层漆的基本涂层的涂敷、真空中的铝蒸发以及进入铝蒸发表面的尿烷透明涂敷。 Sputter plating step comprises applying a coating using a dedicated basic underlying paint, and aluminum was evaporated in vacuo and the evaporated aluminum into the surface of the clear coat of urethane. 因此,当以粗糙状态加工将被涂敷的表面时,溅射电镀工序之后的发光表面可以由光滑加工表面形成。 Thus, when the state of surface roughening processing is to be applied, the light emitting surface after sputtering can be formed by a plating step of machining a smooth surface.

此外,光滑加工的反射表面可以是无光泽的或有光泽的。 In addition, the reflective surface may be machined smooth matt or shiny. 无光泽或有光泽可以通过制备电镀的底涂层液体来改变。 Matte or glossy coating can be varied by the bottom plating liquid preparations.

如图13和14所示,通过从LED 17直接照射的光分量以及通过第一和第二反射部件25和27反射到达的光分量形成的范围W2的数量大于其他区域,以及范围W2的边界是清楚的。 13 and 14, formed by a range from the light component and an LED 17 is directly irradiated by the first and second reflective member 25 and the reflected light 27 reaches the number of components is larger than the other regions W2, and W2 is the range boundaries clearly. 这是因为光被聚焦,以及在范围W2内光通量基本上被平行校正,以便范围w2变为发射照明度高的状态。 This is because the light is focused, and in the range of substantially parallel light flux W2 corrected so w2 range to a state of high emission illumination. 此外,与发光表面由镜面形成的情况相比较,尽管最大照明度被略微地降低,但是其照明度变均匀的范围W2被加宽,以及可以通过一个照明单元300执行更宽的发光范围。 In addition, compared with the case of the light emitting surface is formed from a mirror, although the maximum illuminance is lowered slightly, but it becomes uniform illumination range is widened W2, and may be performed by a wider range of lighting the light emitting unit 300. 此外,相对于LED17的光轴改变平板镜27b的开口角e,可以调整光的偏转状态。 Further, with respect to the optical axis of the mirror plate 27b LED17 changes opening angle E, the deflection state of light may be adjusted. 亦即,当开口角e增加时,照明范围可以被加宽。 That is, when the opening angle increases E, the illumination range can be widened. 当开口角0被减小时,光可以被聚焦在特定的位置中。 When the opening angle 0 is decreased, the light may be focused in a particular position. 在此情况下,优选第一和第二反射部件被分开地设置,而 In this case, the first and second reflection member is preferably arranged separately, and

22不整体地构成,由此自由地调整平板镜27b的开口角^。 22 is not integrally formed, thereby to freely adjust the angle of aperture of the flat mirror 27b ^.

设置使用多色混合型的LED 17作为光源的以上照明单元300,第一反射部件25具有由抛物线表面形成的反射表面(抛物面镜25b),其焦点位置被设为LED 17的发光表面,以及第二反射部件27具有在交叉LED 17的第一反射部件25的发光侧上平行布置的板形反射表面对(平板镜27b)。 Provided multi-color LED 17 or more hybrid illumination unit 300 as a light source, a first reflecting member 25 having a reflecting surface (parabolic mirror 25b) is formed by a parabolic surface, which is set to the focal position of the light emitting surface of the LED 17, and a second two plate-shaped reflection member 27 having a reflective surface arranged in parallel on the light emitting side of the LED 17 of the cross member 25 of the first reflection (flat mirror 27b). 第一和第二反射部件25和27的反射表面由光滑加工表面形成。 First and second reflection surface of the reflective member 25 and 27 are formed of a smooth finished surface. 因此,在宽泛的透视图中,通过光滑加工反射表面反射的光看来是镜反射,但是在微观的透视图中被漫反射,如图13的箭头43所示。 Thus, in broad perspective, the light reflected by the reflecting surface appears smooth processing mirror, but is diffusely reflected at the microscopic perspective, the arrows 13 shown in Figure 43. 结果,颜色被分开而分散的不同频率(波形)分量的光被混合。 As a result, the color light components are separated and dispersed in different frequencies (waveforms) are mixed. 亦即, 分开的蓝色和黄光与白光混合。 That is, separate blue and yellow mixed with white light. 结果,可以高效率聚焦LED的光,以及可以获得均匀照明光,在照射区中不产生任何色彩发暗和阴影,即使当LED的光紧密地照射时。 As a result, high-efficiency LED light focusing, and light illumination uniformity can be obtained, without any dark color and shadow in the illumination region even when irradiated with light of the LED when tightly. 此外,照明光的质量可以被提高。 In addition, the quality of the illumination light can be improved.

此外,当通过设有白色LED 82的照明设备84照明相邻位置时,如图15所示,可以可靠地阻止白色LED 82的蓝光分量和荧光粉激发光分量(黄光分量)的颜色被分开,以便在特定照射区S1和S2上不均匀地出现蓝色区和黄色区或产生阴影。 Further, when the illumination provided by illuminating device 84 adjacent to the position of the white LED 82, as shown in FIG. 15, can be reliably prevented blue components of the white LED 82 and the phosphor excitation light component (yellow component) are separated color , and yellow for a blue region in a specific region and the irradiation region S1 S2 shadows or unevenly. 因此,当使用照明设备100作为书桌上的照明光时,获得均匀照明光,而不降低照明光的质量。 Thus, when using the lighting device 100 as illumination light on the desk, to obtain uniform illumination light without lowering the quality of the illumination light.

此外,由于LED 17的发射光被高效率散射,必须设置其发射波长的差异小的多个LED元件17的需要可以被减小。 Further, since the LED 17 emits light is scattered high efficiency, small differences must be provided which emits a plurality of wavelengths of LED elements 17 may need to be reduced. 在通过镜面反射的照明单元的情况下,照原样使用来自各个LED 17的发射光作为照明光,以及在照明区中清楚区分发射波长的差异。 In the case of specular reflection by the illumination unit, and used as it is emitted from each LED 17 as illumination light, and clearly distinguishable difference in the emission wavelength region of the illumination. 因此,为了阻止其中照明光的局部不同的色彩发暗,需要具有均匀发射波长的LED元件。 Accordingly, in order to prevent illumination light wherein different local dark color, the LED element is required to have a uniform emission wavelength. 但是,反射表面由如上所述的光滑加工表面形成,以便镜反射转变为漫反射。 However, the reflective surface is formed by machining a smooth surface as described above, converted to a diffuse reflection mirror. 尽管LED的发射波长变化,但是光被漫射以变为照明光。 Although the change in emission wavelength of the LED, the light is diffused to become the illumination light. 因此,局部色彩发暗被减小,以及发射波长的变化不被清楚地区分。 Thus, local dark color is reduced, and variation in emission wavelength are not clearly distinguished. 由此,当将形成光滑-加工反射表面时,将用作光源的LED元件的发光性能不需要被严格地选择。 Accordingly, when a smooth - the processing of the reflective surface, the performance of the LED light emitting element as a light source need not be strictly selected. 此外,可以使用便宜的LED元件,由此减小照明设备的成本。 Further, the use of inexpensive LED element, thereby reducing the cost of the lighting device. 此外,尽管通过LED元件制造工序产生具有大的发射波长差异的LED元件,但是可以有效地利用LED元件,而不被浪费。 Further, although the LED generating element having a large difference in wavelength emitted by the LED element manufacturing process, but the LED element can be effectively utilized without being wasted. 因此,当使用本发明的照明单元时,LED元件制造工序也具有优点。 Thus, when the illumination unit of the invention, LED element has an advantage of manufacturing processes.

(第三实施例) 接下来,将描述根据本发明的照明单元的第三实施例。 (Third Embodiment) Next, a third embodiment of the lighting unit according to the present invention will be described.

在该实施例中,提供一种执行宽范围照明的结构。 In this embodiment, there is provided a method of performing a wide range of structural lighting.

图16示出了根据该实施例的照明单元和通过该照明单元的照明度分布的说明性视图。 FIG 16 shows a lighting unit of the embodiment and the explanatory view of the illumination by the illumination unit according to the distribution.

该实施例的照明单元400包括第一实施例所示的多个照明单元100,多个照明单元100被平行布置在阵列中。 The lighting unit 400 of this embodiment includes a first illustrated embodiment of multiple lighting units 100, a plurality of lighting units 100 are arranged in parallel in an array. 各个照明单元100之间的布置间隔被设置为来自相邻照明单元100的照明光分量的强度被调整的整个照明度分布(由图中的一个点链线所示)变为平坦的。 Arrangement interval between the respective lighting unit 100 is set to the illumination intensity from the illumination light component of the adjacent unit 100 is adjusted to the entire illumination distribution (by one-dot chain line in the drawing shown) becomes flat.

根据这种结构,通过排列多个照明单元,其中照明度变均匀的范围可以被延伸,以及将被照明的区域可以被加宽,而不降低照明度。 According to this configuration, by arranging a plurality of lighting units, wherein a uniform illumination variation range may be extended, and the illuminated area may be widened without decreasing the illuminance. 而且,该照明单元100可以与第二实施例的照明单元300相同,以及照明单元100和照明单元300可以互相结合。 Further, the illumination unit 100 may be the same lighting unit 300 of the second embodiment, and a lighting unit 100 and the illumination unit 300 may be bonded to each other. 由此,照明光的强度和均匀性可以被适当地调整。 Thus, the strength and uniformity of the illumination light can be appropriately adjusted.

(第四实施例) 接下来,将描述根据本发明的照明单元的第四实施例。 (Fourth Embodiment) Next, a fourth embodiment of the lighting unit according to the present invention will be described.

在该实施例中,用圆环形状构成照明单元。 In this embodiment, the illumination unit configured with a circular shape.

图17A是圆-环形的照明单元的剖面图,以及图17B是其底视图。 17A is a circle - sectional view of an annular illumination unit, and FIG 17B is a bottom view.

24在该实施例的照明单元500中,沿圆环或圆板中形成的布线基板19 上的圆周方向布置多个(在该实施例中,十二个)LED 17。 24 in the lighting unit 500 of this embodiment, the circumferential direction on the wiring substrate 19 formed along the circular or annular plates are arranged a plurality of (in this embodiment, twelve) LED 17. 对应于各个LED 17,分别布置第一反射部件25。 Corresponding to each LED 17, a first reflection member 25 are arranged. 此外,在第一反射部件25的发光侧上,在内部和外圆周形成具有环形的第二反射部件27,以便覆盖第一反射部件25。 Further, on the light emitting side of the first reflecting member 25, the inner and outer circumference of the second reflecting member 27 has an annular form, so as to cover the first reflecting member 25. 每个第二反射部件27形成为在圆形中连续。 Each of the second reflecting member 27 is formed in a continuous circular.

通过具有这种结构的照明单元500,以环形形成整个单元。 500, the entire unit in an annular form by an illumination unit having such a structure. 因此, 其中在圆环形中均匀出现照明度的范围,以及尽管照明单元500的尺寸较小,但是整个宽范围可以获得均匀照明度。 Accordingly, the scope of which appeared in a uniform illumination of the circular, although a smaller size and a lighting unit 500, but the uniformity can be obtained over a wide range of illuminance. 即使在此情况下,反射表面可以被光滑加工,由此提高散射。 Even in this case, the reflective surface may be smooth processing, thereby increasing scattering. 此外,当具有不同直径的照明单元500被互相结合时,可以以同心圆布置多个照明单元,以及在整个宽范围可以获得均匀照明度,尽管该单元是小型的。 Further, when the illumination unit 500 having different diameters are bonded to each other, can be arranged in a plurality of concentric illumination unit and the illumination uniformity can be obtained over a wide range, although the unit is compact.

(第五实施例) 接下来,将描述根据本发明的照明单元的第五实施例。 (Fifth Embodiment) Next, a fifth embodiment of the lighting unit according to the present invention will be described.

图18图示了具有其它截面结构的反射体部件的结构例子的剖面图。 FIG 18 illustrates a cross-sectional view showing a configuration example of a reflector having a cross-sectional structure of the other member.

在本结构的照明单元600中,在用作光源的LED 17的光路前面布置凸面镜47,如图1S所示。 In the illumination unit 600 of this configuration, the optical path in front of the LED 17 as a light source disposed convex mirror 47, as shown in FIG 1S. 因此,从LED 17发射的大多数光被照射在凸面镜47上。 Thus, most of the light emitted by the LED 17 is irradiated from the convex mirror 47. 将被反射的凸面镜47上照射的光被第一反射部件25的抛物面镜25a或第二反射部件27的板镜27a平行校正。 The light irradiated on the convex mirror 47 is reflected by the mirror plate 27 of the first reflection member 27a collimating parabolic mirror 25 or the second reflecting member 25a. 此外,没有被照射在凸面镜47的某些光被第二反射部件27的板镜27a平行校正。 In addition, some of the light is not irradiated on the plate 47 is a convex mirror 27a reflecting the collimated second member 27. 由此,必须通过第一和第二反射部件25和27偏转从LED 17发射的光,以被平行校正。 Thus, the deflected light to be emitted from the LED 17 through the first and second reflecting members 25 and 27 so as to be corrected in parallel. 然后,在发射照明度高的状态中该光变为指向光路的前端。 Then, in a state of high emission illumination light becomes the front end point of the optical path.

如上面的例子,反射体部件的结构可以被适当地修改。 As in the example above, the structure of the reflector member may be suitably modified. 此外,可以进行以下改进。 In addition, the following improvements can be made. 例如,第二反射部件27的平板镜27a可以由曲面镜形成,以便在预定距离聚焦光(以形成图像)。 For example, the second reflecting mirror 27a of the plate member may be formed by a curved mirror, so as to focus the light in a predetermined distance (to form an image). 此外,相对于LED 17的光轴,改变平板镜27a的开口角0 (参考图14),可以调整光的偏转状态。 Further, with respect to the optical axis of the LED 17 change the opening angle of 0 flat mirror 27a (see FIG. 14), you can adjust the state of deflection. 换句话说, 因为开口角e增加,照明范围可以被加宽。 In other words, because the increase in the opening angle E, the illumination range can be widened. 因为开口角e被减小,光可以被聚焦在特定的位置中。 E is reduced because the opening angle, the light can be focused at a particular position. 在此情况下,优选第一和第二反射部件被分开地设置,而不整体地构成,由此自由地调整平板镜27b的开度角e。 In this case, the first and second reflecting means is preferably provided separately, rather than integrally formed, thereby freely adjust the opening angle of the flat mirror 27b e.
