发光装置 Light emitting means

技术领域 FIELD

本发明是关于发光二极管等发光装置。 The present invention is a light emitting device of the light-emitting diodes. 背景技术 Background technique

使用发光二极管(Light Emitting Diode, LED)的LED灯,正朝向液晶显示器、手机、信息终端等的背光和室内外广告等多方面飞速发展。 A light emitting diode (Light Emitting Diode, LED) LED lamp, is toward the liquid crystal display, a mobile phone, an information terminal such as a backlight and indoor and outdoor advertising and other aspects of rapid development. 进而,LED灯的寿命长、可靠性高,而且具有功耗低、耐冲击性强、显示色纯度高、可实现小巧轻薄化等的特点,所以不仅适用于产业用途,而且也正尝试应用于普通照明用途。 Furthermore, long-life LED lamp, high reliability, and low power consumption, high impact resistance, show a high color purity can be achieved and so the characteristics of small and light, it is not only applicable to industrial applications, but is also applicable to try general lighting purposes. 当将这样的LED灯应用于各种用途时,关^fc在 When such an LED lamp used in various applications, the shut ^ fc

于获得白色发光。 To obtain a white light.

作为利用LED灯来实现白色发光的代表方式,可列举下述三种方式:(1 ) 使用发出蓝、绿及红的各色光的三种LED芯片的方式;(2)将蓝色发光的LED芯片与黄色至橙色发光的荧光体加以组合的方式;(3 )将紫外线发光的LED芯片与蓝色、绿色及红色发光的三色混合焚光体加以组合的方式。 As a representative embodiment using a white light LED lamp to achieve include the following three ways: (1) using three different LED chips emit blue, green and red color light manner; (2) the blue light LED yellow to orange light emitting chip and a phosphor combination of them; (3) an ultraviolet light-emitting LED chip with blue, green and red three-color luminescent light mixture burned combining manner. 这些方式中, 一般而言,得到广泛实用化的是(2)的方式。 In these ways, in general, it is widely practical (2) manner. 并且,作为应用了所述(2)的方式的LED灯的构造, 一般而言是下述构造:使混合有荧光体的透明树脂流入到配备有LED芯片的杯型框架(frame)内,使树脂固化,从而形成含有荧光体的树脂层(例如,参照日本专利特开2001 - "8516公报)。 除了如上所述的炮弹型LED元件或SMD (Surface Mounting Device,表面装配元件)类型以外,为了实现高亮度化,还开发出了在基板(board)上搭载有多个芯片的板上芯片(Chip On Board, COB ),并受到了瞩目。作为普通照明用所要求的特性,除作为LED灯的高效率(发光效率)以外,还有作为色彩呈现指标的显色性,尤其是平均显色指数Ra。该显色性要求摹仿荧光灯等的Ra 80-85或大于等于Ra 9G等的调节范围(lineup)。 LED lamp structure and manner as the application of (2), the following construction is generally: a transparent resin mixed with a fluorescent material flows into the cup-shaped frame equipped with the LED chip (Frame), so that curing the resin to form a resin layer containing a phosphor (e.g., refer to Japanese Patent Laid-open 2001-- "Publication 8516). Other than the above elements of the shell-shaped LED or SMD (surface mounting device, surface mounted components) type, in order high luminance, but also developed as an ordinary illumination requirements for characteristics on a substrate (board) has a plurality of chips mounted on a chip on board (chip on board, COB), and received attention., in addition to an LED lamp other than the high efficiency (luminous efficiency), as well as the color rendering index of color, especially color rendering index Ra. the color rendering fluorescent lamp of claim imitation Ra 80-85 Ra 9G equal to or greater than the adjustment range, etc. (lineup).

显色性是指,将接近自然光的照明作为标准光,来对光源照射下的色彩呈现度进行评估,显色指数是以数值来表示用样品光源及标准光分别对JIS所规定的测试色进行照明时所产生的色偏移的大小。 Color refers to the close to natural light illumination as a standard light to be evaluated, the color rendering index is a numerical value of color in the light source exhibits degrees represents the light, respectively prescribed by JIS test color for a sample source and Standards the size of the illumination color shift produced. 显色指数有平均显色指数Ra及特殊显色指数Ri ,平均显色指数Ra表示测试No. 1 ~ No. 8的显色指数值的平均值。 The average color rendering index has a color rendering index Ra and the special color rendering indexes Ri, the average color rendering index Ra represents an average color rendering index value test of No. 1 ~ No. 8. 特殊显色指数Ri表示测试No. 9 ~ No. 15各自的特殊显色指数值。 Special color rendering index Ri represents 9 to the respective values ​​of special color rendering index No. 15 Test No.. 显色指数Ra,是以指数来表示是否忠实地再现了在作为标准光源的白色光源照射下的色彩,原则上,显色指数Ra越接近100,则显色性越好。 Color rendering index Ra, to indicate whether the index is faithfully reproduced colors under white light source as a standard source, in principle, color rendering index Ra is closer to 100, the better the color.

一般而言,平均显色指数Ra较高的所谓高显色类型的LED灯,是通过来自LED芯片的蓝色发光,利用从发出波长为540 - 560咖的光的YAG (Yttrium Aluminum Garnet,钇铝石榴石)等黄色系荧光体而来的黄色发光、与从发出波长为620 nm的光的红色发光体而来的红色发光,来合成显色性优异的白色光。 In general, the higher the average color rendering index Ra of the so-called high color type LED lamp, a blue light emitting from the LED chip through the use of a wavelength emitted from 540--560 coffee light of a YAG (Yttrium Aluminum Garnet, yttrium aluminum garnet) and the like from a yellow-based phosphor emitting yellow, and red emission at 620 nm wavelength of emitted light from the red emitter, synthesized excellent color rendering properties of white light. 为了提高平均显色指数Ra,通常是如上所述般使用发出红色光的红色荧光体,但红色荧光体不仅将46G nm附近的蓝色光用于激发,而且也会将从绿色焚光体发出的绿色光及从黄色系荧光体发出的黄色光用于激发,所以如杲使用红色发光的荧光体,则LED灯的发光效率会降低约一半,从而存在著发光效率大幅降低的问题。 In order to improve the color rendering index Ra, usually as described above emits red light, a red phosphor, but only the red phosphor 46G nm blue light used to excite the vicinity, but also from the burning of the green light given off phosphor and green light emitted from the yellow-based yellow phosphor is excited for light, so as Gao red light, the luminous efficiency of the LED lamp will be reduced to about half, so that there is a significant decrease in luminous efficiency.

因此,正尝试使用红色发光的发光元件,而非红色发光的荧光体。 Thus, the light emitting element is trying to use red light, rather than red light emitting phosphor. 然而,来自该发^件的红色发光并非宽频(broad)发光,其半值宽度较窄,因此虽可能使色温降低,但平均显色指数Ra的上升幅度较小。 However, the hair from the red light emitting element is not ^ Broadband (Broad) light, a half-value width is narrow, so although the color temperature may decrease, but the smaller the average rise of the color rendering index Ra. 因此,难以实现高显色性时的平均显色指数Ra 85乃至90或90以上。 Thus, it is difficult to achieve when the general color rendering index Ra 85 color rendering 90 or 90 or even more.

除此以外,对于光色亦即色温而言,当考虑到HID (high-intensity discharge,高强度放电)灯、灯泡、荧光灯时,需要直到各种色温6700 K、 5000 K、 4200 K、 3000 K ( 2850 K)为止的调节范围。 In addition, the color temperature of the light i.e. color, when considering the HID (high-intensity discharge, high-intensity discharge) lamps, light bulbs, fluorescent lamp, various color temperatures required until 6700 K, 5000 K, 4200 K, 3000 K adjustment range (2850 K) until. 一般而言,为了对应这样的调节范围,而需要仅对应于各色温的白色LED灯。 Generally, such adjustment to the corresponding range, and only needs to correspond to each color temperature white LED lamp. 另一方面,提出了一种可变色LED灯(例如,参照日本专利特开2005 - 100799 //H艮)。 On the other hand, we propose a color LED light (e.g., refer to Japanese Patent Laid-Open 2005 - 100799 // H Gen). 然而,此种可变色LED在从白色LED开始的调整中,仅可向一方向变色,因此存在下述问题:色偏差(DUV)产生偏移而远离黑体放射,较之色温的变化而言,因偏差的变化而导致色的品质降低。 However, in such a variable color LED, color can only be adjusted from the start of the white LED in one direction, there is a problem: color shift (DUV) deviated away from the black body radiation, compared in terms of color temperature change, deviation due to changes caused by lower color quality. 因此,不仅需要实现可向一方向变色,而且必须实现可向所需的(任意)方向变色。 Thus, not only can achieve color in one direction, and the color must be realized (any of) the desired direction.

由此可见,上述现有的发光装置在结构与使用上,显然仍存在有不便与缺陷,而亟待加以进一步改进。 Thus, in the above-described conventional light-emitting device using the structure, there is clearly still problems and disadvantages, and the urgent need to be further improved. 为了解决上述存在的问题,相关厂商莫不费尽心思来谋求解决之道,但长久以来一直未见适用的设计被发展完成,而一般产品又没有适切结构能够解决上述问题,此显然是相关业者急欲解决的问题。 In order to solve the above problems, the firms did not dare to think hard and to seek a solution, but has long been seen to be applicable to the design of the development is complete, and general product and no relevance structure can solve the above problems, this is obviously related businesses anxious to solve the problem. 因此如何能创设一种新型结构的发光装置,实属当前重要研发课题之一,亦成为当前业界极需改进的目标。 So how can we create a new structure of the light-emitting device, it is currently one of the important research and development issues, has become the current industry in dire need of improvement goals.

有鉴于上述现有的发光装置存在的缺陷,本发明人基于从事此类产品设计制造多年丰富的实务经验及专业知识,并配合学理的运用,积极加以研究创新,以期创设一种新型结构的发光装置,能够改进一般现有的发光装置,使其更具有实用性。 In view of the defects of the conventional light-emitting device, the present invention is based on such products for many years engaged in the design and manufacture a wealth of practical experience and professional knowledge, and with the use of scientific principle, be actively pursued research and innovation, in order to create a new type of light-emitting structure means in general can be improved conventional light emitting apparatus, it is more practical. 经过不断的研究、设计,并经过反复试作样品及改进后,终于创设出确具实用价值的本发明。 Through continuous research, design, and repeated the test sample and make improvements through, and finally the creation of the present invention indeed has practical value.

The light transmitting binder, for example, preferably silicon resin-based binder.

如图1以及图2所示,各半导体发光元件2的电极与靠近配置在半导体发光元件2两侧的电路图案3,利用接合线(bonding wire) 6而连接着。 As shown in FIG. 1 and FIG. 2, each of the electrodes 2 and the semiconductor light emitting element 3 disposed in close, a circuit pattern 2 by a bonding wire on both sides of the semiconductor light emitting element (bonding wire) 6 is connected to the. 进而,位于所述两列电路图案3列的另一端侧的端侧电路图案3b彼此也利用接合线6而连接着。 Further, the circuit pattern of the other end side of the end of the two circuit patterns 3 is 3b also be connected to each other by the bonding wire 6. 因此,该实施形态的情况下,各半导体发光元件2 串联地连接着。 Thus, the case of this embodiment, each of the semiconductor light emitting element 2 are connected in series. 由以上所述的装置基板4、反射层31、电路图案3、各半导体发光元件2、粘合层32以及接合线6,而形成发光装置1的面发光源。 The apparatus according to the above substrate 4, the reflective layer 31, the circuit pattern 3, each of the semiconductor light emitting element 2, adhesive layer 32 and the bonding wires 6, to form a surface emitting light emitting device 1.

反射器34并非对应于每一个或者每数个半导体发光元件2而个別地设置,而是包围反射层31上的所有半导体发光元件2的单一反射器,反射器34例如是由长方形的框来形成,半导体发光元件2配置在由所述框所形成的凹部7内。 The reflector 34 is not corresponding to each of one or a plurality of the semiconductor light emitting element 2 disposed individually, but rather all the reflective layer surrounding the semiconductor light emitting element 31 on a single reflector 2, the reflector 34, for example, to a rectangular frame is formed, the semiconductor light emitting element 2 is disposed in the recess formed by the frame 7. 反射器34粘合固定在反射层31上,反射器34的内部收纳着多个半导体发光元件2以及电路图案3,并且所述的一对供电图案部3c、 3d位于反射器34的外部。 The reflector 34 is fixed to the adhesive on the reflective layer 31, the reflector 34 is housed inside the semiconductor light-emitting element 2 and the circuit pattern 3 and the pair of power supply pattern section 3c, 3d of the reflector 34 outside. 反射器34例如可由合成树脂所成形,其内周面成为反射面。 The reflector 34 is molded by synthetic resin, the inner peripheral surface of the reflecting surface. 反射器34的反射面可以通过将A1或Ni等反射率较高的金属材料进行蒸镀或电镀而形成,除此以外,还可以通过涂布对可见光的反射率较高的白色涂料而形成。 Reflected by the reflector surface 34 can be a high reflectivity metal material A1 or Ni plating or vapor deposition is formed, in addition, also to visible light may be formed of high reflectivity by coating white paint. 或者,也可以在反射器34的成形材料中混入白色粉末,使反射器34自身成为对可见光的反射率较高的白色。 Alternatively, a white powder may be mixed in the molding material of the reflector 34, of the reflector 34 itself becomes high visible light reflectance of white. 作为所述白 Examples of the white

含荧光体树脂层9是通过下述方式而形成:针对每个发光部群,使用分配器(dispenser)等注入装置,将以规定的配合量使各种焚光体混合而成的液状热固性树脂,沿着排列在一直线上的各半导体发光元件2而呈线状地涂布、填充,以对应于每条线(line)而完全地填埋反射层31的表面以及排列在一直线上的各半导体发光元件2以及接合线6等,以获得所需的单色光,并且通过加热而使热固性树脂硬化。 Phosphor-containing resin layer 9 is formed in the following manner: each light emitting unit for the blending amount group, a dispenser (a dispenser) injecting apparatus and the like, will cause various predetermined light burning a liquid obtained by mixing a thermosetting resin , are arranged along the straight line in each of the semiconductor light emitting element 2 and is linearly coated, filled, corresponding to each line (line) and completely filled with the reflective layer 31 and a surface arranged on a straight line each of the semiconductor light emitting element 2 and the bonding wires 6 and the like, to obtain a desired monochromatic light, and the thermosetting resin is cured by heating. 同样,对应于排列在一直线上的各半导体发光元件2的规定的每条线,而形成有包含发出所需色的光的突光体的荧光体层。 Similarly, each line corresponds to a predetermined arrangement in the semiconductor light emitting element 2 of the straight line, to form a phosphor layer comprising a projection light has a desired color of the emitted light. 如此,当使各发光部群的荧光体层(对于蓝色光而言为透明树脂层)呈线状地形成时,可容易地制造,而且制造成本较低。 Thus, when the phosphor layer of each light emitting portion group (for blue light in terms of a transparent resin layer) is formed when linearly, can be easily manufactured, and the manufacturing cost is low. 另外,在使用分配器等注入装置来涂布含有荧光体的热固性树脂时,较好的是以例如14 Pa'S左右的高粘度来进行涂布。 Further, by applying a thermosetting resin containing a phosphor in a dispenser or the like using the injection means it is preferably such as high viscosity of about 14 Pa'S to be coated. 而且,在涂布所述热固性树脂之前,也可以对应于每条线而预先在基板4上设置用来分别涂布的壁部。 Further, before coating the thermosetting resin, corresponding to each line may be set in advance are used to coat the substrate 4 on the wall portion. 如此,相同发光部群中的焚光体,是使用以相同种类、相同配合比而配合的二液型硅树脂而形成在LED蓝色芯片2上,因此可抑制来自荧光体的单色光的发光的不均匀,可获得荧光体所发出的光的特性、例如发光强度或色度(例如色温)等的不均匀较少的发光。 Thus, the burning of the same light emitting portion group is to use the same kind, and with the same compounding ratio of two liquid silicone resin is formed on the blue LED chip 2 can be suppressed from monochromatic phosphor uneven light emission is obtained by light emitted from the phosphor characteristics such as emission intensity or chromaticity less (e.g., color temperature) or the like uneven light emission.

其次,对于向基板上配置各发光部群的排列图案进行说明。 Secondly, the arrangement pattern for the respective light-emitting portions arranged in groups onto the substrate will be described.

图3是表示使3群发光部群分别沿着排列在一直线上的各半导体发光元件2而呈线状地平行配置的发光装置的一例的示意图。 FIG 3 shows a portion of the light that the bulk Group 3 schematically shows an example of the light-emitting device are arranged in parallel along the linear arrangement of each of the semiconductor light emitting element 2 and on a straight line shape. 如图3所示,发光装置l包括:受到蓝色光的激发而发出绿色光的发光部群2G;发出红色光的发光部群2R;以及发出蓝色光的发光部群2B。 As shown, the light emitting device 3 l comprising: a light emitting portion group by being excited by the blue light emits green light 2G; a light-emitting portion of red light 2R group; and the group of the light emitting unit emits blue light FIG. 2B. 该实施形态的发光装置可获得蓝色光、绿色光以及红色光。 The light emitting device of this embodiment can be obtained blue light, green light and red light. 分别呈线状地平行配置的3群发光部群是由:使来自蓝色LED芯片2的蓝色光透过透明树脂层而放射出的发光部群、受到所述蓝色光的激发而发出红色光的发光部群以及受到所述蓝色光的激发而发出绿色光的发光部群来依次构成。 3 respectively as a bulk optical linear portion parallel-group by: the blue from the blue LED chip of the light emitting portion 2 through the transparent resin layer group emitted by the excitation of the blue light and emits red light a light emitting portion emitting portion group, and the group is excited by the blue light to emit green light are sequentially configured. 各发光部群亦可分别设定电路图案3,以能够个別地发出单色光。 Each group of light emitting portions may respectively set the circuit pattern 3, so as to be individually emit monochromatic light. 如此,通过使3种发光部群沿着各半导体发光元件2而呈线状地平行形成,可进一步抑制各个发光部群中的突光体的不均匀,尤其可进一步抑制因涂布量引起的不均匀。 Thus, by three kinds of light-emitting portions 2 and the group is formed in a parallel line along the respective semiconductor light emitting element can be further suppressed unevenness projecting light emitting portion of the respective group, in particular can be further suppressed by the coating amount of cause uneven. 而且,由于是呈线状地涂布,所以制造也较容易。 Further, because it is linearly coated, it is also easier to manufacture.

图4是表示使4群发光部群分别呈线状地平行配置的发光置的一例的示意图。 4 FIG. 4 shows that the bulk light emitting portion group schematic configuration example of opposed parallel linear shape, respectively. 发光装置1包括:受到蓝色光的激发而发出绿色光的发光部群2G;发出黄色光的发光部群2Y;发出红色光的发光部群2R;以及发出蓝色光的发光部群2B。 A light emitting apparatus comprising: excitation by blue light to emit green light emitting unit group 2G; emits yellow light emitting unit 2Y group; a light-emitting portion of red light 2R group; and a group of blue light emitting section emits FIG. 2B. 该实施形态的发光装置可获得蓝色光、绿色光、黄色光以及红色光。 The light emitting device of this embodiment can be obtained blue light, green light, yellow light and red light. 4群发光部群是由:发出(透过)蓝色光的发光部群、发出绿色光的发光部群、发出黄色光的发光部群以及发出红色光的发光部群来依次构成。 4 is a bulk light unit group: emitted (transmitted) light emitting portion group blue light, emits green light emitting portion group, the light emitting portion emits light, and a group of yellow light emitting unit emits red light group sequentially configured. 所述4群各发光部群亦可分别设定电路图案3,以能够个别地发出单色光。 The light emitting portion 4 of each group may each group setting circuit pattern 3, so as to be individually emit monochromatic light. 如此,通过配置4群发光部群,可容易地进行色度的可变色的调整。 Color adjustment can thus, by arranging the light mass portion 4 group, the chromaticity can be easily performed.

而且,在图4中,也可以在受到蓝色光的激发而发出绿色光的发光部群2G与发出红色光的发光部群2R之间排列红色发光元件。 Further, in FIG. 4, may be excited by blue light to emit red light-emitting elements are arranged between the light emitting unit group 2G 2R green light emitting unit emits red light group. 此时,可维持高显色性,且可获得色温的降低以及更高的发光效率。 At this time, we can maintain high color, and the lower the color temperature and higher luminous efficiency can be obtained. 而且,在发出绿色光的发光部群2G与发出红色光的发光部群2R之间排列红色发光元件,使发光部群2G与发光部群2R隔开来,因此发出绿色光的发光部群2G的绿色光难以在红色发光荧光体的激发中被吸收,从而可抑制发光效率的降低。 Further, the light emitting unit emits green light and a light-emitting unit group 2G 2G group light emitting portion groups arranged between the red light 2R red light emitting element, the light emitting portion and the light emitting unit group 2G 2R group separates, thus emitting green light difficult to absorb green light in the red light emitting phosphor is excited, thereby reducing the emission efficiency can be suppressed.

而且,在图4中,也可以将发出黄色光的发光部群2Y变更为红色发光元件。 Further, in FIG. 4, a light-emitting portion may be a group of yellow light is changed to red light emitting element 2Y. 此时,在一个发光部群中,在被覆于发光元件上的荧光体层中使用红色荧光体而形成发出红色光的发光部群2R,进而使用红色发光元件,因此可维持高显色性,并且可获得色温的降低以及更高的发光效率。 In this case, a light emitting portion group, to form a light emitting unit emits red light 2R group in the phosphor layer covering the light emitting element on a red phosphor, a red light emitting element and further use, thereby maintaining a high color rendering, and the lower the color temperature can be obtained and higher luminous efficiency.

图5是表示使4群发光部群分别呈两段线状地平行配置的发光装置的一例的示意图。 FIG. 5 shows a portion of the light that the bulk Group 4 schematically shows an example of a light emitting device arranged parallel two linear shape, respectively. 此处,所谓呈两段线状地平行配置是指,使基板4上的LED 发光元件2,以与利用接合线连接且排列在-^直线上的各半导体发光元件2 Here, the two were linearly arranged in parallel means that the LED light emitting element 2 on the substrate 4, to be connected with a bonding wire and arranged - ^ on a straight line of each semiconductor light emitting element 2

部各自的范围内,使4群各发光部群呈线状地配置,以使上部与下部的各发光部群两个两个地相互平行。 The inner portion of each range, so that the light emitting portions 4 groups each group are arranged linearly, so that each group of the light emitting portion of the upper and lower two by two parallel to each other. 如此,通过使4群发光部群分别呈两段线状地平行配置,可更容易地进行单色光的混色。 Thus, two linearly arranged in parallel, can be more easily performed by mixing monochromatic light mass portion 4 respectively form groups.

图6是表示使4群各发光部群呈矩阵状地配置的发光装置的一例的示意图。 FIG 6 is a diagram showing that the light emitting portion groups each group 4 schematically shows an example of a light emitting device arranged in a matrix form. 所谓呈矩阵状地配置,是指如图6所示般使发光部群配置成格子状的情况。 The so-called in a matrix configuration, means as shown in FIG. 6 so that the light emitting portion groups arranged in a grid pattern. 4群各发光部群也可以分别设定电路图案3,以能够个别地发出单色光。 4 the light emitting portion groups each group may be set to the circuit pattern 3, respectively, so as to be individually emit monochromatic light. 如此,通过使4群各发光部群呈矩阵状地配置,可更容易地进行来自各发光部群的单色光的混色,可省略光扩散构件33,或者至少可削薄该光扩散构件33的厚度,从而可抑制因光扩散构件33的使用所导致的亮度的下降。 Thus, by making the light emitting portion of each group of 4 groups arranged in a matrix, color mixture can be performed more easily from a monochromatic light emitting portion of each of the groups, the light diffusing member 33 may be omitted, or at least light diffusing member 33 of the skived thickness to decrease the brightness can be suppressed by using the light diffusing member 33 is caused.

而且,该实施形态的发光装置1是C0B模组,因而可使基板4上的LED 芯片2的间隔较窄(窄间距),因此可获得更高亮度的发光装置。 Further, the light emitting device 1 of this embodiment is C0B module thus allows the LED chips spaced on the substrate 42 is narrow (narrow pitch), the light-emitting device may obtain higher luminance. 而且,由于可缩小LED芯片2的间隔,因此可获得将从各发光部群获得的单色光进一步混色而成的光。 Further, since the LED chip 2 narrow interval, thus monochromatic light obtained from a light emitting portion of each population obtained from mixed color light further.

该实施形态的LED灯1中,所施加的电能由LED芯片2转换成主波长为420 - 480 nm (例如460咖)的蓝色光并i文射出。 The LED lamp of Embodiment 1, the applied power is converted by the LED chip 2 into a main wavelength of 420 - 480 nm (e.g. 460 coffee) and the blue light emitted text i. 所;故射出的蓝色光通 The; it emitted blue light flux

15过各发光部群中的各荧光体而转换成更长波长的光。 15 through each phosphor portion of each light-emitting group is converted into light of a longer wavelength. 根据来自各发光部群 The light emitting portion from each group

的发光色(单色),与从LED芯片放射的蓝色光进行混色而成为单色光。 The emission color (monochrome), color mixing of the light emitted from the blue LED chips becomes monochromatic. 由来自所述各荧光体的单色光进行混色而成的白色光从LED灯1放出。 By the monochromatic light from each phosphor obtained by mixing a white light emitted from the LED lamp. 以此方式构成的发光装置可维持高显色性且发光效率高,并且可获得所需色度的光的发光。 The light emitting device constituted in this way can maintain high color rendering properties and high luminous efficiency, light emission can be obtained and a desired chromaticity. 而且,通过各发光部群中的荧光体的种类、配合量以及/或荧光体树脂的厚度(光路长度)的调整,可获得所需色温下的与黑体放射的偏差得到了抑制的白色光。 Further, by the type of the phosphor portions of the respective light-emitting group, the amount and / or thickness of the phosphor resin (optical path length) is adjusted, and obtain the desired variation in color temperature of the black body radiation of white light is suppressed. 例如,白色光的色温为6500 ~ 6700 K(昼白色)、 2850 - 3000 K (灯泡色)。 For example, the color temperature of white light of 6500 ~ 6700 K (daylight white), 2850 - 3000 K (incandescent color). 因此,可提供适用于普通照明的发光装置。 Thus, the light emitting device is suitable for general lighting can be provided.
