Description

LED照明器具 LED lighting fixture

技术领域 FIELD

[0001] 本发明涉及在光源中具备LED的LED照明器具,特别是涉及适合用作以充分的亮度对远方对象物进行演出照明的投光灯的LED照明器具。 [0001] The present invention relates to a LED light source in the LED lighting apparatus, particularly relates to a brightness suitable for use as a sufficient distance for the object to be illuminated show floodlight LED lighting apparatus.

背景技术 Background technique

[0002] 在供建筑物等的演出照明所用的照明器具中,在其光源中广泛采用容易高输出化的HID(High Intensity Discharge,高压气体放电)灯。 [0002] In the lighting fixture for performing a lighting buildings, etc. are used, in which the light source is widely used in high output easily HID (High Intensity Discharge, high intensity discharge) lamp. 近年来,高寿命化、灯具可以小型、轻量化的LED作为光源而得到关注,另外还作为照明器具而不断实用化。 In recent years, a longer service life, the lamp can be small, lightweight LED as a light source to give attention also as a practical lighting equipment continuously.

[0003] S卩、在以HID灯作为光源的照明器具中是用反射镜来进行配光控制,为了提高器具效率就需要使用尽可能反射HID灯的发射光这一大小的反射镜,所以器具大型、重量化。 [0003] S Jie, the HID lamp as a light source to a lighting fixture with a reflecting mirror is a light distribution control is performed, in order to improve the efficiency of the appliance it is necessary to use as the HID lamp light emission reflection mirror of this size, the appliance large, the weight of the. 而在以LED作为光源的照明器具中,LED是从其发射面发射光的构造,所以一般都是在该发射面配置透镜进行配光控制的结构。 In an LED lighting apparatus as a light source, the LED is configured to emit light from the emission surface, the lens structure are generally disposed in the light distribution control emission face. 根据这一结构,就能够用小型、轻量的透镜来控制LED的全部发射光,就可以使器具变得小型、轻量化(例如,参照专利文献I)。 This configuration, it is possible to use a small, lightweight lens controls all LED emits light according to the implement can be made compact, lightweight (e.g., refer to Patent Document I).

[0007] 但是,在照射对象物处于离开数十〜数千米以上的远方时,为了以充分的亮度对照射对象物进行照明,就需要在光源中采用非常高输出的LED。 When [0007] However, the object to be irradiated is away more than several tens to several kilometers far, a sufficient brightness for the irradiation object to be illuminated, requires the use of a very high output LED in the light source. 另外,如以往那样,在配光控制中使用了透镜时,将在照射面上发生色像差。 In addition, as in the past, the use of the light distribution controlling lens, the chromatic aberration occurs on the irradiated surface.

[0008] 为了解决这一问题,可以考虑在配光控制中使用反射镜,但在单纯使用反射镜时,与透镜相比无法控制光源的全部发射光,因此轴光度降低而无法在远方确保所希望的亮度。 [0008] To solve this problem, consider using a mirror in the light distribution control, but when the mirror is used alone, compared with the lens can not control all of the radiation light source, so that the shaft can not be reduced to ensure that the luminosity in the distance desired brightness. 在光源中采用了HID灯的以往的照明器具中,因该HID灯自身比较大,故尽管因反射镜未完全反射的光所造成的轴光度不足变得显著,但通过使HID灯高输出化以增加光轴上的光束来弥补轴光度不足。 Employed in the light source of the conventional luminaire HID lamps, because of the HID lamp itself is relatively large, so that although the lack axis brightness due to light reflection mirror is not totally reflected in the result becomes significant, but by making the HID lamp high output to increase the beam axis on the optical axis to compensate for lack of luminosity. 但是,在LED中,即便提高输出也不可期望如HID灯那种程度的光束增加,所以在使用LED的状态下不能获得所希望的轴光度。 However, in the LED, nor even desirable to increase the output light beam such that the degree of increase in the HID lamp, it can not obtain a desired luminous intensity in a state where the shaft using an LED.

[0009] 本发明就是鉴于上述情形而完成的,其目的在于提供一种能够以充分的亮度对远方的对象物进行照明的LED照明器具。 [0009] The present invention has been accomplished in view of the above, and its object is to provide LED lighting apparatus capable of illuminating a distant object with sufficient luminance.

[0010] 本说明书中包含2010年6月24日申请的日本国申请2010-144308的全部内容。 [0010] This manual contains application June 24, 2010 the entire contents of Japanese Application 2010-144308 of.

[0011] 为了达到上述目的,本发明提供一种LED照明器具,其特征在于,具备多个LED和按上述LED而具有抛物反射面的反射单元,该抛物反射面在底部设置了面对上述LED的始端开口,对于上述抛物反射面,分别使从配置上述LED的底部到终端开口的轴长取为能够获得超狭角配光的长度,上述终端开口的直径取为使1/2光束角为5〜7度的直径,而且相互平行地设置各个上述抛物反射面,以分别从上述抛物反射面发射的光在离开既定距离的照射场相重叠的间距来分别配置上述LED及抛物反射面,并且在将上述抛物反射面沿着长轴、分割成相互为同一形状而成的分割抛物反射面上分别形成反射膜,将各个分割抛物反射面接合起来而构成上述抛物反射面。 [0011] To achieve the above object, the present invention provides an LED lighting apparatus comprising LED as described above and a plurality of LED reflector unit having a parabolic reflective surface, the parabolic reflective surface is provided on the bottom face of the LED the leading end opening to said parabolic reflective surface, respectively, the shaft length from the bottom of the configuration of the LED to the terminal opening is taken to be possible to obtain the length of the ultra-narrow angle of light distribution, the diameter of the terminal opening is taken to make the half beam angle diameter 5 ~ 7 degrees, and arranged parallel to each other each of the parabolic reflective surface, the light respectively emitted from the parabolic reflective surface exiting the irradiation field a predetermined distance from the overlapping pitch configuration of the LED and the parabolic reflective surface, respectively, and a reflective film formed in the above-described respective parabolic reflective surface along the major axis, each divided into the same shape obtained by dividing a parabolic reflecting surface, a parabolic reflective surface of each split joined together to constitute said parabolic reflector.

[0012] 另外本发明的特征在于,在上述LED照明器具中,还具备收纳上述LED及上述抛物反射面的由导热性材料构成的灯体箱,使上述抛物反射面的终端开口侧从该灯体箱的正面突出,并用树脂制成的透明的前面罩来覆盖该突出的部位。 [0012] Further features of the present invention, in the LED lighting apparatus further includes a lamp body case made of a thermally conductive material accommodation of the LED and said parabolic reflecting surface, so that the terminal above parabolic reflector opening side from the lamp the front tank member protrudes, and a transparent front cover made of resin to cover the projecting portion.

[0013] 根据本发明,使从配置LED的底部到终端开口的轴长取为能够获得超狭角配光的长度,终端开口的直径取为使1/2光束角为5〜7度的直径,所以较以往而言能够使平行光线沿抛物反射面的长轴集中而提高轴光度。 [0013] According to the present invention, the shaft length from the bottom to the configuration of the LED's terminal is taken as an opening length to obtain ultra-narrow angle light distribution, the diameter of the opening of the terminal is taken that the angle of the beam diameter 5 ~ 7 1/2 degrees , it is possible to than in the past in terms of the parallel light rays along the major axis of the parabolic reflective surface to improve the focus axis brightness. 进而,远方照射场的扩散得以抑制,从而能够维持充分的照度。 Further, the diffusion distance of the irradiation field is suppressed, sufficient illuminance can be maintained.

[0014] 另外,这种抛物反射面的长度较通常而言变得非常长,所以难以形成均匀的反射面,但在本发明中,由于在将该抛物反射面沿着长轴分割成相互为同一形状而成的分割抛物反射面上分别形成反射膜,将各个分割抛物反射面接合起来而构成抛物反射面,所以能够简单地形成均匀的抛物反射面。 [0014] Further, the length of the parabolic reflector is more general becomes very long, it is difficult to form a uniform reflective surface, but in the present invention, since the parabolic reflective surface is divided along the major axis to each other same shape obtained by dividing a parabolic reflecting surface are formed a reflective film, each of the parabolic reflector is divided by bonding a parabolic reflective surface, it is possible to easily form a uniform parabolic reflective surface.

[0029] 下面,更详细地说明各部分。 [0029] Next, each portion in more detail.

[0030] 图3是表示LED单元3的结构的图,图3 (A)是LED单元3的俯视图,图3 (B)是放大表示LED单元3所具备的LED9的图,图3 (C)是放大表示该LED9的其他例子的图。 [0030] FIG. 3 is a diagram showing a configuration of the LED unit 3, FIG. 3 (A) is a plan view of the LED unit of FIG. 3, FIG. 3 (B) is an enlarged LED unit 3 is provided in FIG LED9, and FIG 3 (C) It is an enlarged view of another example of the LED9 FIG.

[0031] 如该图所示,LED单元3在横长延伸的一枚电路基板13上将5个LED9以一定的间距P (后面详述)配置于一列而构成,在该电路基板13的背面侧安装有各LED9的点灯电路。 [0031] As shown, LED unit 3 on a circuit board 13 that is elongated 5 LED9 constant pitch P (described in detail later) and arranged in a configuration, the back surface of the circuit board 13 LED9 mounted each side of the lighting circuit. 在本实施方式中,通过使用5个输出功率约为20W (瓦特)的LED9而构成输出功率约为100W (瓦特)的LED单元3。 In the present embodiment, by using an output power of about 5 20W (watts) is constituted LED9 LED unit outputs power of about 100W (Watts) 3.

[0032] 如图3 (B)所示,LED9将多个(在图示例中为4个)LED元件(LED芯片)15封装成一个而构成。 [0032] FIG. 3 (B) shown, LED9 plurality of (in the illustrated example four) LED element (LED chip) 15 is configured into a package. 即、LED9具备俯视大致呈正方形的封装基板17,在该封装基板17的上表面17A凹设俯视大致呈圆形的反射器19,在该反射器19的中心部O配置多个LED元件15,由设置在封装基板17周围的正负电极21、23对各LED元件15提供功率以进行点灯。 I.e., substantially square LED 9 includes a plan view of a package substrate 17, the upper surface 17A of the package substrate 17 is recessed substantially circular plan view of the reflector 19, the reflector center portion O 19 arranged plurality of LED elements 15, provided by the positive and negative electrodes 21, 23 disposed around the package substrate 17 to each LED lighting element 15 for power. 另外,在反射器19中填充有一同覆盖各LED元件15的密封树脂25。 Further, the reflector 19 is filled with a sealing resin covering the LED elements 2515 of. 上述LED元件15分别在大致中央具有发光点X,并将这些LED元件15呈格子状相互密集配置,由此可以在光学设计上作为一个具有将这些LED元件15包围起来这一大小的发光点Q来对待。 Of the LED light emitting element 15 has a substantially central point in the X, and the LED elements 15 densely arranged in a grid pattern with each other, whereby these as having LED elements 15 surround the light emitting point Q on the size of the optical design to be treated.

[0033] 此时,在图3 (B)的例子中,由于在发光点Q的中心部O没有LED元件15的发光点X,所以在将它们作为一个发光点Q进行光学设计时,照射场的轮廓变得不鲜明,又因中心部O为光轴,故轴光度也降低。 [0033] In this case, in the example of FIG. 3 (B), since the light emitting point Q of the central portion of the light emitting point O X 15 without the LED elements, so when they are optically designed, the irradiation field as a light emitting point Q contour becomes unclear, because the center portion of the optical axis O, so that the shaft is also reduced luminosity. 因而,如图3 (C)的例子所示,通过采用在反射器19的中心部O配置LED元件15的发光点X,并在该LED元件15的周围配置其他LED元件15而构成发光点Q的LED9A,照射场的轮廓将变得鲜明,再者轴光度也获得提高。 Thus, the example in FIG. 3 (C) is shown disposed in the center of the reflector by using O 19 unit LED element emitting point X 15 and other LED elements arranged around the LED element 15 constituting the light emitting point 15 and Q the LED9A, the contour of the irradiation field becomes clear, addition-axis luminous intensity is also enhanced.

[0034] 但是,若发光点Q变大就无法作为点光源来对待。 [0034] However, if Q becomes large emission point can not be treated as a point light source. 因此,优选缩小LED元件15的尺寸或者减少个数,以便相对于后述的抛物反射面11,发光点Q的大小落入在光学设计上能够看作点光源的程度。 Thus, the LED elements 15 is preferably reduced in size to reduce the number or order with respect to the parabolic reflective surface 11 described later, the size of the light emitting point Q extent in optical design can be regarded as a point light source falls. 但是,若使LED元件15小型化或者减少个数,则将它们封装化后得到的LED9的高输出化将变得困难。 However, when the LED elements 15 or reducing the number of downsizing, high output will LED9 after packaged thereof it will become difficult to obtain. 因此,作为充分地照亮数十米〜数千米的远方的光源,输出将变得不足。 Thus, a sufficiently illuminated to several tens kilometers distant light source, the output becomes insufficient. 另外,若采用发光点Q较大并且高输出的LED9,则如上述那样,照射场的轮廓将变得不鲜明。 Further, the use of a light emitting point Q is large and high-output LED 9, then, as described above, the irradiation field contour becomes unclear. 换言之,因配光控制的精度下降而使器具效率也下降,所以为了充分地照亮远方,就需要徒劳地提高LED9的输出。 In other words, light distribution control due to reduction in the accuracy also decreases the efficiency of the appliance, it is sufficient to illuminate the distance, it is necessary to increase the output LED9 in vain.

[0035] 如果将抛物反射面11加大至能够将发光点Q看作点光源的程度,这一问题就能够解决。 [0035] If the parabolic reflective surface 11 to increase the light emitting point Q can be regarded as a point light source extent, this problem can be solved. 但是,抛物反射面11变得非常大,将招致器具的大型、重量化而有损在光源中采用LED9的优点。 However, parabolic reflector 11 becomes very large, it will incur a large weight to the detriment of the advantages of using the appliance LED9 in the light source. 尤其是,在本实施方式中,如后述那样因抛物反射面11的轴长较长,故器具的大型化变得显著。 In particular, in the present embodiment, as described later, as a result of longer axial length parabolic reflector surface 11, so the size of the instrument becomes significant.

[0036] 因而在本实施方式中,不是用一个LED9来构成光源,而是使用多个(在本实施方式中为5个)LED9来构成一个LED单元3。 [0036] Thus in the present embodiment, instead of using a light source configured to LED9, but the use of a plurality of (in the present embodiment, five) to form a LED9 LED unit 3. 根据这一结构,由于能够降低各个LED9的输出,所以能够使发光点Q变小,从而能够实现更准确的配光控制并且不会招致抛物反射面11的大型化。 According to this configuration, it is possible to reduce the output of each LED9, it is possible to make the light emitting point Q becomes smaller, thereby enabling more accurate control of light distribution and without incurring large parabolic reflecting surface 11.

[0037] 图4是表不反射单兀5的结构的图,图4 (A)是其正视图,图4 (B)是其俯视图,图4 (C)是其侧视图。 [0037] FIG. 4 is a table that does not reflect the structure of a single Wu FIG. 5, FIG. 4 (A) is a front view, FIG. 4 (B) is a plan view, FIG. 4 (C) is a side view.

[0038] 反射单元5是在单元主体30上根据LED9的间距P横排设置抛物反射面11而构成。 [0038] The reflection unit 5 is a parabolic reflector 11 is configured according to LED9 horizontal pitch P of the unit main body 30 is provided. 如图4 (B)所示,该单元主体30的侧视形状沿上述抛物反射面11大致呈抛物线形状,如图2 (B)所示,单元主体30的底部31以位于LED单元3的电路基板13上这一方式被支承于灯体箱7。 FIG. 4 (B), the shape of the cell body 30 is a side view along the parabolic reflector 11 is substantially parabolic shape, the circuit 2 (B) shown in the bottom cell 31 of the body 30 of the LED unit 3 in FIG. this way the substrate 13 is supported by the lamp body case 7. 另外,如图4所示,反射单元5的结构为,具备用通过各个抛物反射面11的长轴K的面二分割成相互为同一形状而形成的分割抛物反射面单元30A、30B,并用螺钉对其进行连接。 Further, as shown in FIG. 4, the structure of the reflecting unit 5 is provided with a through respective parabolic major axis K of the reflecting surface 11 of the face divided into two parts to each other are formed in the same shape divided parabolic reflective surface means 30A, 30B, and screw its connection.

[0039] 图5是分割抛物反射面单元30A的俯视图。 [0039] FIG. 5 is a plan view of the divided parabolic reflector unit 30A. 此外,另一分割抛物反射面单元30B也与此图所示的结构相同,故省略图示及说明。 Further, the other divided parabolic reflector unit 30B shown in this figure are also the same configuration, illustration and description thereof is omitted.

[0040] 分割抛物反射面单元30A由例如铝等具有高导热性的原材料通过铸造而成型,如该图所示,具有露出沿长轴K纵向进行二分割的抛物反射面11的面。 [0040] The parabolic reflector splitting unit 30A is molded by a material such as aluminum having a high thermal conductivity by casting, as shown in the figure, having a major axis along the exposed surface K for longitudinal parabolic reflector 11 divided into two. 在铸造后对该面实施用于提高抛物反射面11的反射率的铝蒸镀,之后将分割抛物反射面单元30A、30B进行接合而构成上述反射单元5。 After the casting surfaces embodiment for improving the reflectivity of aluminum deposition parabolic reflecting surface 11, after reflecting surfaces divided parabolic unit 30A, 30B are joined to form the reflecting means 5. 根据这种结构,即便在抛物反射面11较深的情况下,也能够在其表面整体均匀地形成铝蒸镀膜,从而简单地获得效率良好的反射镜。 According to this structure, even in the case of 11 deep parabolic reflective surface, it is possible to integrally form an aluminum deposited film uniformly on the surface thereof, thereby easily obtaining good efficiency mirrors.

[0041] 反射单元5的抛物反射面11是将反射面设为抛物面的凹面镜,在其底部31设置·有面对LED9的始端开口33,使从该始端开口33面对抛物反射面11内的LED9发射的发射光平行光化后从终端开口35射出。 Parabolic reflector [0041] The reflection unit 5. 11 is a reflecting surface to a parabolic concave mirror, has faced LED9 in its bottom 31 disposed · leading end opening 33, the inner opening from the leading end 33 facing the parabolic reflection surface 11 LED9 emitted light emitted from the rear end opening 35 emits collimated. 通过平行光化后射出,就能够抑制光在远方扩散以防止·照度下降。 After collimated by injection, can be suppressed to prevent the light-diffusing illuminance decrease in the distance.

[0042] 但是,单单平行光化后射出,无法解决到照射对象物的距离变得较远时的光量不足,如何提高轴光度就变得很重要。 [0042] However, only the collimated emission, can not be resolved from the object to be irradiated becomes insufficient when the amount of light far, how to improve the luminance axis becomes important. 因而,在本实施方式中,为了提高各个抛物反射面11上的轴光度,如下设定各抛物反射面11的形状。 Accordingly, in the present embodiment, in order to improve the on-axis luminous intensity of each parabolic reflection surface 11, the shape of each set as follows parabolic reflecting surface 11.

[0043] S卩、如图5所示,使从配置LED9的底部31到终端开口35的轴长L取为获得超狭角配光的长度,而且终端开口35的直径Dl取为1/2光束角为5〜7度的长度而形成抛物反射面11。 [0043] S Jie, shown in Figure 5, the opening 35 from the bottom 31 to the configuration of the terminal LED9 axial length L is taken to be the length of an ultra-narrow angle light distribution, and a terminal opening diameter Dl 35 is set to be 1/2 length of the beam angle of 5 ~ 7 degrees parabolic reflective surface 11 is formed. 这里,在本实施方式中,超狭角配光是为照射离开数十〜数千米以上的地方所使用的配光,即1/2光束角为5〜7度的配光。 Here, in the present embodiment, the ultra-narrow-angle light distribution of irradiating light exiting several tens to several kilometers where used, i.e., 1/2 of the light distribution angle of the light beam 5 ~ 7 degrees.

[0044] 具体而言,在本实施方式中,LED9采用宽度W (图2 (A))约6. 4mm的LED,抛物反射面11的始端开口33的直径D2(图5)设为与该LED9的宽度W相同程度的大小,约11mm,并且从该始端开口33到终端开口35的轴长L为约116. 55mm,另外终端开口35的直径Dl(图5)取为1/2光束角为5〜7度(在本实施方式中为5度)的直径,即约84. 9mm。 [0044] Specifically, in the present embodiment, using LED 9 width W (FIG. 2 (A)) LED to about 6. 4mm, the leading end 11 of the parabolic reflector opening diameter D2 33 (FIG. 5) is set to the LED9 same degree of size width W of about 11mm, and the opening of the axial length L of about 35 1/2 was taken beam angle 116. 55mm from the opening start end to the terminal 33, the other terminal 35 of the opening diameter Dl (FIG. 5) It is 5 ~ 7 degrees (in the present embodiment, five degrees) in diameter, i.e., about 84. 9mm.

[0045] 由此,抛物反射面11的终端开口35的开口度即直径Dl相对于轴长L较以往而言成为非常小的形状,另外,截光角Θ (图5)也变小,约为13. 03度,所以较以往而言能够使平行光线沿抛物反射面11的长轴K集中以提高轴光度。 [0045] Accordingly, the terminal 11 of the parabolic reflective surface 35 of the openings, i.e. diameter Dl relative to the axial length L than in the past in terms of a very small shape, additionally, cutoff angle [Theta] (FIG. 5) also becomes small, about to 13.03 degrees, more conventional terms can be made parallel light along the long axis of the parabolic reflective surface is concentrated to increase K 11 axis brightness. 进而,由于1/2光束角较小为5〜7度,所以远方照射场的扩散得以抑制,远方的照度得以提高。 Further, since a smaller beam angle of 5 ~ 7 1/2 degrees, the diffusion distance of the irradiation field is suppressed, distant illumination is improved.

[0046] 如上所述,在反射单元5中通过从多个抛物反射面11分别照射光来提高总输出。 [0046] As described above, in the reflection unit 5 to increase the total output from a plurality of parabolic reflecting surfaces 11 are irradiated with light. 此时,若各个抛物反射面11的光在既定远方的照射场分离,则就无法在该照射场获得所希望的照度。 At this time, if the light of each parabolic reflector 11 is separated a predetermined distance in the irradiation field, it will not achieve the desired illuminance in the illumination field. 从而,考虑从各抛物反射面11所发射的光的扩散来设定抛物反射面11 (LED9)的间距P,以使得各个发射光在既定远方的照射场具有重叠。 Thus, considering the diffusion of the light emitted from the respective surface 11 to set the parabolic reflector parabolic reflector surface 11 (LED 9) of the pitch P, so that each emit light having a predetermined irradiation field overlap distance. 据此,具备LED单元3及反射单元5的LED照明器具I的轴光度得以提高,就能够在远方维持充分的照度。 Accordingly, the reflecting unit 3 and the LED lighting apparatus comprising LED unit 5 luminosity shaft I is improved, sufficient illuminance can be maintained in the distance.

[0047] 此时,通过使各抛物反射面11的长轴K相互平行,就能够遍及长距离维持较高轴光度而不会在离开既定距离的照射场发生聚光。 [0047] At this time, the respective major axis parabolic reflector K 11 parallel to each other, can be maintained over long distances without high luminosity axis in the irradiation field a predetermined distance away from the condenser occurs.

[0048] 返回到前面的图2,灯体箱7正视呈横长的箱形形状而构成,用导热性较高的例如铝合金而形成。 [0048] FIG 2 is returned to the front of the lamp body front tank 7 was horizontally long box shape and configuration, with high thermal conductivity such as aluminum alloy is formed. 在其正面侧设置有收纳反射单元5及LED单元3的收纳部41,在该收纳部41的背后侧设置有收纳电源电路等的空间,另外还设置有安装用的支承臂43。 And the accommodating portion 5 is provided with a reflective LED unit housing unit 3 on its front side 41, the back side of the housing portion 41 is provided with a housing space of the power supply circuit and the like, there is also provided a support arm 43 mounted. 另外,如图I及图2所示,灯体箱7的收纳部41成型到反射单元5的前端侧(终端开口35侧)朝向正面突出的深度,并设置有聚碳酸酯等轻量的树脂制透明罩(前面罩)45以覆盖此突出的地方。 Further, as shown in FIG. I and 2, housing portion 41 of the lamp body case 7 formed to the front end side of the reflecting unit 5 (terminal-side opening 35) projecting toward the front of the depth, and provided with a lightweight polycarbonate resin made transparent cover (front cover) 45 covering this prominent place. 通过这样使反射单元5的前端侧从灯体箱7突出,除获得外观设计性优异的LED照明器具I夕卜,还能够缩短灯体箱7的前后长度,故可以轻量化及低成本化。 By making the front end side of the reflecting unit 5 protrudes from the lamp body case 7, except with the design of the LED lighting apparatus excellent Bu Xi I, the lamp can be shortened longitudinal length of the tank 7, it is possible to reduce the weight and cost. 其中,灯体箱7的前后长度被设定成能够使LED单元3的发热从灯体箱7充分散热的程度。 Wherein the longitudinal length of the lamp body case 7 is set so that the LED unit 3 to heat sufficient degree of heat radiation from the lamp body of the tank 7. 此时,反射单元5的抛物反射面11的轴长L较以往而言长,所以该反射单元5的热容量增加,因此能更加缩短灯体箱7。 In this case, the axial length of the parabolic reflector unit 11 of the reflective surface 5 than in the past in terms of the length L, the heat capacity of the reflecting unit 5 is increased, it is possible to further shorten the lamp body case 7.

[0049] 如以上说明的那样,根据本实施方式,抛物反射面11为如下结构,即从配置LED9的底部31到终端开口35的轴长L取为获得超狭角配光的长度,并将终端开口35的直径D2取为1/2光束角为5〜7度的直径。 [0049] As explained above, according to the present embodiment, the parabolic reflector 11 in a structure, the opening 35, i.e. from the bottom of the configuration LED9 of 31 to the final shaft length L is taken to be the length of an ultra-narrow angle light distribution, and end opening 35 diameter D2 is set to be 1/2 the diameter of the beam angle of 5 ~ 7 degrees.

[0050] 根据这一结构,较以往而言能够使平行光线沿抛物反射面11的长轴K集中以提高轴光度。 [0050] According to this structure, compared with the conventional parallel light can be made in terms of parabolic reflector along the major axis to increase the concentration of K 11 axis brightness. 进而,因1/2光束角较小,故远方的照射场的扩散得以抑制,从而能够维持充分的照度。 Further, due to the smaller beam angle 1/2, so that the diffusion distance of the irradiation field is suppressed, sufficient illuminance can be maintained. 据此,就获得以约100W (瓦特)输出功率的LED单元3作为光源,能够以充分的亮度照亮离开100米的对象物的LED照明器具I。 Thereby, it is obtained at about 100W (Watts) output power of the LED unit 3 as a light source, capable of illuminating the LED lighting apparatus 100 m away from the object with sufficient luminance I.

[0051] 另外,根据本实施方式,采用如下结构,即具备多个LED9而构成LED单元3,并构成每个LED9具有抛物反射面11的反射单元5,另外相互平行地设置抛物反射面11,并以从各个抛物反射面11所发射的光在离开既定距离的照射场相重叠的间距P来分别配置多个LED9及抛物反射面11。 [0051] Further, according to the present embodiment, to adopt a configuration that includes a plurality LED9 constitute the LED unit 3, and constituting each LED9 reflection unit 5 reflecting surface 11 having a parabolic additionally provided in parallel parabolic reflective surface 11 to each other, and the light from the respective parabolic reflector 11 is emitted in a predetermined distance away from the overlapping exposure field pitch P of the plurality are arranged to LED9 and parabolic reflective surface 11.

[0052] 根据这一结构,不用勉强地使一个LED9高输出化也能在离开既定距离的照射场获得充分的照度。 [0052] According to this structure, without making a LED9 reluctantly a high output can be obtained sufficient illuminance exposure field separated by a predetermined distance. 另外,由于各抛物反射面11相互平行,所以能够遍及长距离维持较高轴光度而不会在离开既定距离的照射场进行聚光。 Further, since each of the parabolic reflector 11 parallel to each other, it can be maintained over long distances without high luminosity shaft in a predetermined distance away from the irradiation field condenses.

[0053] 另外根据本实施方式,在沿着反射单元5的抛物反射面11的长轴K分割而成的相互为同一形状的分割抛物反射面单元30A、30B上分别进行铝蒸镀,将各个分割抛物反射面单元30A、30B合起来而构成反射单元5。 [0053] Further according to the present embodiment, the major axis K parabolic reflective surface 11 along the reflecting unit 5 is obtained by dividing each divided into the same shape of the parabolic reflective surface unit. 30A, 30B, respectively on the aluminum deposition, the respective dividing means parabolic reflective surface 30A, 30B together to form the reflection unit 5. 据此,即便在抛物反射面11较深的情况下也能够在其表面整体均匀地形成铝蒸镀,从而简单地获得效率良好的反射镜。 Accordingly, even if it is possible to form an aluminum vapor-deposited uniformly over the entire surface thereof at 11 is deep parabolic reflective surface, thereby easily obtaining good efficiency mirrors.

[0054] 另外根据本实施方式,采用如下结构,即具备收纳LED单元3及反射单元5的由导热性材料构成的灯体箱7,使反射单元5的抛物反射面11的终端开口35 —侧从该灯体箱7的正面突出,并用树脂制透明罩45来覆盖该突出的部位。 [0054] Further according to the present embodiment, to adopt a configuration that includes a storage LED unit 3 and the reflecting means comprises a lamp body case thermally conductive material having 75 to the reflecting unit parabolic reflective surface 5 of the terminal 11 of the opening 35 - side front of the cabinet body 7 projecting from the lamp, and a transparent resin cover 45 to cover the protruding portion. 根据这一结构,获得外观设计性优异的LED照明器具1,另外还能够缩短灯体箱7的前后长度,故可以轻量化及低成本化。 According to this configuration, the design is obtained of the LED lighting apparatus 1 is excellent in, in addition to the lamp body front-rear length can be shortened tank 7, it is possible to reduce the weight and cost. 进而,反射单元5的抛物反射面11的轴长L较以往而言长,所以该反射单元5的热容量增力口,因此可以使灯体箱7更加缩短化。 Further, the axial length of the parabolic reflector unit 11 of the reflective surface 5 than in the past in terms of the length L, the heat capacity of the reflection unit energizing opening 5, so that the lamp body case 7 can be more shortened.

[0057] 如这些附图所示,在LED照明器具100中,采用上下配置两部分的结构,所述两部分为将三个LED9及抛物反射面11配置于一列的反射单元105A和将两个LED9及抛物反射面11配置于一列的反射单元105B。 [0057] As shown in these drawings, the LED lighting apparatus 100, the configuration using two upper and lower part of the configuration, the two divided into three LED9 and the parabolic reflective surface 11 is arranged on a reflection unit 105A, and the two LED9 and parabolic reflector 11 is arranged on a reflecting unit 105B. 关于各反射单元5的制造方法以及光学特性如第I实施方式中说明的那样。 About each of the reflection unit 5 and the manufacturing method of the optical characteristics such as I described in the embodiment described above.
