[0003] 本发明的背景 [0003] Background of the invention

技术领域 FIELD

[0004] 本发明涉及固态灯及灯泡,且尤其涉及能够产生全向发射图案(样式,pattern)的有效且可靠的基于发光二极管(LED)的灯及灯泡。 [0004] The present invention relates to solid state light bulb and, particularly, to be able to produce a full and efficient and reliable to transmit a pattern (pattern, pattern) of the light emitting diode (LED), and light bulbs.

背景技术 Background technique

[0005] 白炽灯或灯泡或基于灯丝的灯或灯泡通常用作家用设施及商用设施的光源。 [0005] or an incandescent bulb or a filament based lamp or a light bulb is usually used as household and commercial facilities facilities. 然而,这种灯为效率极度低下的光源,其中多达95%的输入能量主要呈热或红外线能量的形式而损失。 However, such a lamp is the extremely low efficiency of the light source, which up to 95% of the input energy is mainly in the form of infrared energy or heat loss. 白炽灯的一个常见替代形式(所谓的紧凑荧光灯(CFL))在将电力转换为光方面更有效,但要求使用有毒材料,这种有毒材料以及其各种化合物可造成慢性及急性中毒,并且可导致环境污染。 A common alternative form of incandescent lamps (so-called compact fluorescent lamps (the CFL)) is more effective in converting light to electricity, but requires the use of toxic materials, such toxic materials as well as various compounds may cause chronic and acute poisoning, and may cause environmental pollution. 用于提高灯或灯泡的效率的一个解决方案为使用固态器件(诸如,发光二极管(LED))而非金属灯丝来产生光。 For improving the efficiency of a lamp or bulb solution is to use solid-state devices (such as light emitting diodes (the LED)) and non-metallic filament to generate light.

[0006] 发光二极管一般包括夹置于掺杂类型相反的层之间的半导体材料的一个或多个活性层。 [0006] The light emitting diode generally includes one or more interposed active layer of semiconductor material of opposite doping type between the layers. 当将偏压施加于掺杂层上时,空穴和电子注入于活性层中,空穴和电子在活性层中重组合以产生光。 When a bias is applied to the doped layers, holes and electrons injected into the active layer, holes and electrons are recombined in the active layer to generate light. 光从活性层以及从LED的各个表面发出。 Light emitted from the active layer and from all surfaces of the LED.

[0007] 为了在电路或其他相似布置中使用LED芯片,已知的是将LED芯片封入于封装件中以提供环境和/或机械保护、颜色选择、光聚焦等。 [0007] In order to use an LED chip in a circuit or other like arrangements, it is known to the LED chip enclosed in the package to provide environmental and / or mechanical protection, color selection, light focusing and the like. LED封装件还包括用于将LED封装件电连接至外部电路的电导线、触点或迹线。 LED package further comprises a means for electrically connecting the LED package to an external circuit electrical leads, contacts or traces. 在图1中所示的典型LED封装件10中,借助于焊料结合或导电环氧树脂将单个LED芯片12安装于反射杯13上。 In a typical LED package shown in FIG. 1, by means of a solder bond or conductive epoxy to a single LED chip 12 is mounted on a reflective cup 13. 一个或多个引线结合部11将LED芯片12的欧姆触点连接至导线15A和/或15B,这种导线可附接至反射杯13或与反射杯13形成一体。 Or a plurality of wire bonding portions 11 of the LED chip 12 is connected to an ohmic contact wires 15A and / or 15B, which may be attached to the wire 13 or the reflective cup 13 is formed integrally with the reflective cup. 该反射杯可填充有密封剂材料16,该密封剂材料可含有诸如磷光体(phosphor,荧光剂) 的波长转换材料。 The reflective cup 16 may be filled with a sealant material, the sealant material may contain a wavelength conversion material such as phosphor (Phosphor, fluorescent agents). 由LED发出的在第一波长的光可由磷光体吸收,该磷光体可回应地发射第二波长的光。 The light emitted by the LED at a first wavelength by a phosphor absorbing light of a second wavelength response of the phosphor may emit. 接着将整个装配件密封于透明保护树脂14中,该保护树脂可模制成透镜形状, 以使自LED芯片12发出的光准直。 The entire assembly is then sealed in a transparent protective resin 14, the lens may be molded to the shape of the resin protection, to collimate light emitted from the LED chip 12. 虽然反射杯13可在向上方向上引导光,但在光被反射时(即,一些光由于实际反射器表面的小于100%的反射率而可能被反射杯吸收),可能发生光学损失。 While the reflective cup 13 may direct light in an upward direction, but when the light is reflected (i.e. some light because the actual surface of the reflector is less than 100% reflectivity of the reflective cup may be absorbed), the optical loss may occur. 另外,热滞留对于封装件(诸如图1中所示出了的封装件10)来说可能是个问题,因为可能难以经由导线15A、15B引出热。 In addition, heat retention for the package (such as shown in FIG. 1 out of the package 10), it can be a problem, since it may be difficult via wires 15A, 15B heat extraction.

[0008] 图2中所示的传统LED封装件20可能更适合于可产生更多热的高功率操作。 Conventional LED package shown in [0008] FIG. 220 may be better suited to produce more heat may be high-power operation. 在LED 封装件20中,一个或多个LED芯片22安装至载体(诸如,印刷电路板(PCB)载体、基板或基台(submount) 23)上。 In the LED package 20, one or more LED chips 22 are mounted to a carrier (such as a printed circuit board (PCB) carrier, substrate or submount (submount) 23) on. 安装于基台23上的金属反射器24环绕LED芯片22且反射由LED芯片22发出的光以使光远离封装件20。 Mounted on a metal base 23 around the reflector 24 and the reflected light from the LED chip 22 emitted by the LED chip 22 to the package member 20 away from the light. 反射器24还提供对LED芯片22的机械保护。 The reflector 24 also provides mechanical protection to the LED chip 22. 在LED芯片22上的欧姆触点与基台23上的电迹线25A、25B之间形成一个或多个引线结合连接件27。 On the LED chip 22 is electrically ohmic contacts on the base 23 traces 25A, 25B are formed between the one or more wire bond connection 27. 接着以密封剂26覆盖所安装的LED芯片2 2,该密封剂可提供对芯片的环境及机械保护,同时还充当透镜。 Followed by the sealant 26 covers the LED chip 22 is mounted, the sealing agent may provide environmental and mechanical protection to the chips while also acting as a lens. 金属反射器24通常借助于焊料或环氧树脂结合而附接至载体。 Metal reflector 24 is typically by means of a solder or epoxy and the binding is attached to the carrier.

[0009] 可通过包括一个或多个磷光体的转换材料来涂布LED芯片(诸如,图2的LED封装件20中所找到的LED芯片),其中所述磷光体吸收LED光中的至少一些。 [0009] LED chips may be coated (such as the LED package of FIG. 2, the LED chip 20 found) by converting material comprises one or more phosphors, wherein the phosphors absorbing at least some of the LED light . LED芯片可发射不同波长的光,使得其发射来自LED及磷光体的光的组合。 LED chips can emit different wavelengths of light, such that light emitted from a combination of LED and phosphor. 可使用许多不同的方法用磷光体涂布LED芯片,其中一种合适方法描述于美国专利申请第11/656,759号及第11/899,790号中,这两个专利申请为Chitnis等人的申请且题目均为"Wafer Level Phosphor Coating Method and Devices Fabricated Utilizing Method"。 Many different methods can be used with a phosphor coated LED chips, wherein one suitable method is described in U.S. Patent Application Serial No. 11 / 656,759 and 11 / 899,790, which patent application is a two Chitnis et al the application and are entitled "Wafer Level Phosphor Coating Method and Devices Fabricated Utilizing Method". 可替换地,可使用诸如电泳沉积(EPD)的其他方法来涂布LED,其中合适的EPD方法描述于Tarsa等人的题为"Close Loop Electrophoretic Deposition of Semiconductor Devices" 的美国专利申请第11/473, 089号中。 Alternatively, other methods may be used such as electrophoretic deposition (EPD) is applied to the LED, wherein a suitable EPD method described in Tarsa et al., Entitled "Close Loop Electrophoretic Deposition of Semiconductor Devices" U.S. Patent Application No. 11/473 , No. 089.

[0010]具有在附近的或作为直接涂层的转换材料的LED芯片已用在各种不同封装件中, 但遭遇到基于器件的结构的一些限制。 [0010] or as having in the vicinity of the direct conversion material coated LED chip is used in various packages but met with some restrictions based on the structure of the device. 当磷光体材料在LED外延层上或在LED外延层附近(且在一些例子中包括在LED上的保形涂层)时,磷光体可直接经受由芯片产生的热,该热可使磷光体材料的温度增加。 When the phosphor material on an LED epitaxial layer or near the LED epitaxial layer (and in some examples comprise a conformal coating on the LED), the phosphor may be directly subjected to the heat generated by the chip, the phosphor can heat temperature of the material increases. 另外,在这种情况下,磷光体可经受来自LED的极高浓度或通量的入射光。 Further, in this case, the phosphor can be subjected to incident light from the LED is extremely high concentration or throughput. 由于转换过程通常并非100%有效,因此在磷光层中产生与入射光通量成比例的过量热。 Since the conversion process is generally not 100% effective, so incident light is generated proportional to the flux of excess heat in the phosphor layer. 在接近于LED芯片的紧凑磷光层中,此可导致磷光层中的温度明显增加,因为在小区域中产生大量的热。 In the phosphor layer close to the compact LED chip, which may cause the temperature of the phosphor layer is increased significantly, since a large amount of heat in a small area. 当磷光体颗粒嵌入于低热导率材料(诸如,硅树脂,所述低导热性材料不提供用于对在磷光体颗粒内产生的热的有效耗散路径)中时,此温度增加可加剧。 When phosphor particles embedded in the low thermal conductivity material (such as silicon resin, and the low thermal conductivity material does not provide a path for effectively dissipating heat generated in the phosphor particles) in time, this temperature increase can be intensified. 这种升高的操作温度可造成磷光体及周围材料随着时间的流逝而劣化,并且造成磷光体转换效率的降低及转换颜色的偏移。 This may cause increased operating temperatures and the surrounding phosphor material deteriorated over time, and cause the color shift reduced and the conversion efficiency of the phosphor conversion.

[0011] 同样已开发出利用固态光源(诸如,LED)结合与LED分离的或相对于LED处于远端(远离LED)的转换材料的灯。 [0011] have been developed using the same solid state light source (such as an, LED) in combination with an isolated or LED in the LED lamp with respect to the distal end (away from the LED) of the conversion material. 这种布置公开于Tarsa等人的题为"High Output Radial Dispersing Lamp Using a Solid State Light Source"的美国专利第6,350,041 号中。 US Patent No. 6,350,041 Such an arrangement is disclosed in Tarsa et al., Entitled "High Output Radial Dispersing Lamp Using a Solid State Light Source" in. 此专利中所描述的灯可包括经由分离器将光透射至具有磷光体的分散器的固态光源。 Lamp described in this patent may comprise solid state light source to transmit light having a phosphor of the disperser via a separator. 该分散器可使光按照所期望的图案来分散和/或通过经由磷光体或其他转换材料将该光中的至少一些转换成不同波长来改变其颜色。 This allows light disperser according to the desired pattern to disperse and / or via a phosphor or other light conversion material in the at least some is converted into a different wavelength to change its color. 在一些实施例中,分离器使光源与分散器隔开足够的距离,使得当光源载运室内照明所必需的升高电流时,来自光源的热将不传递至分散器。 In some embodiments, the light separating means disperser spaced a sufficient distance, such that when the light source carrier indoor lighting necessary current increases, the heat from the light source is not transmitted to the disperser. 附加的远端磷光体技术描述于Negley等人的题为"Lighting Device"的美国专利第7,614, 759号中。 Additional techniques are described in a distal phosphor Negley et al., Entitled "Lighting Device" U.S. Patent No. 7,614, No. 759.

[0012] 合并有远端磷光体的灯的一个潜在缺点为其可具有不期望的视觉或审美特征。 [0012] The distal end of the lamp incorporating a phosphor may have a potential drawback for its undesirable visual or aesthetic characteristics. 当灯并不产生光时,灯可具有与标准爱迪生灯泡的典型白色或透明外观不同的表面颜色。 It does not generate light when the lamp, the lamp may have a standard Edison bulb typically white or transparent appearance of the different surface colors. 在一些例子中,灯可具有黄色或橙色外观,其主要由磷光体转换材料产生。 In some instances, the lamp may have a yellow or orange appearance, which is mainly produced by phosphor conversion material. 此外观对于许多应用而言可被认为是不期望的,在所述这些应用中,当灯不照明时,其可造成关于周围的建筑元件的审美问题。 For many applications this appearance may be considered undesirable in the application of these, when the lamp is not illuminated, it can cause aesthetic problems on the surrounding building elements. 这可使消费者对这种类型的灯的总体接受度具有负面影响。 This can have a negative impact on overall consumer acceptance of this type of lamp.

[0013] 另外,与在转换过程期间在磷光层中产生的热可经由附近的芯片或基板表面传导或耗散的保形的或邻近的磷光体布置相比,远端磷光体布置可经受于不充足的导热热耗散路径。 [0013] Further, the heat generated in the phosphor layer during the conversion process may be compared via a chip or a substrate disposed near the surface of the conductive or dissipative conformal phosphor or adjacent, the distal end of the phosphor is arranged to be subjected to inadequate thermal heat dissipation paths. 在无有效的热耗散通路的情况下,热隔离的远端磷光体可遭受升高的操作温度,该升高的操作温度在一些情况下可甚至高于可比较的保形涂布层中的温度。 In the absence of effective heat dissipation path, the distal end of the phosphor can be subjected to thermal isolation elevated operating temperatures, increase the operating temperature may be in some cases even higher than comparable conformal coating layer temperature. 此情形可抵消通过将磷光体相对于芯片置放于远端所达成的一些益处或所有益处。 This may be counteracted by the phosphor on the chip placement reached the distal end of some of the benefits or benefits with respect to all. 换言之,相对于LED芯片的远端磷光体置放可减少或消除由于在操作期间在LED芯片内产生的热的对磷光层的直接生热,但是所形成的磷光体温度减小可部分地或全部地由于在光转换过程期间磷光层自身中产生的热及缺少用于耗散此所产生的热的合适热路径而被抵消。 In other words, the distal end of the phosphor LED chip placement may reduce or eliminate the direct heat of the heat generated in the LED chip during operation of the phosphor layer, but the temperature of the phosphor may be formed partially reduced or relative all due phosphorescence layer itself during the process of converting light to heat and the lack of this heat for dissipating the generated heat a suitable path is canceled.

[0014] 影响利用固态光源的灯的实施和接受度的另一问题与由光源自身发出的光的性质有关。 [0014] Effect of the use of solid state light sources and a further embodiment of problems with the acceptance of the lamp properties of light emitted by the light source itself relevant. 为了制造基于LED光源(及相关联的转换层)的有效灯或灯泡,通常希望将LED芯片或封装件以共平面布置放置。 In order to manufacture LED-based light source (and the associated conversion layer) of the active or light bulb, or an LED chip is often desirable to package a co-planar arrangement is placed. 这促进了制造且可通过允许使用传统生产设备和工艺而减少制造成本。 This facilitates manufacture and can be reduced by allowing the use of conventional production equipment and manufacturing process costs. 然而,LED芯片的共平面布置通常产生前向光强度分布(profile,轮廓)(例如,朗伯分布)。 However, a coplanar arrangement of the LED chips generally produced before distribution (Profile, profile) (e.g., Lambertian distribution) to the light intensity. 这种光束分布在固态灯或灯泡意欲替换具有更好全向光束图案的传统灯(诸如, 传统白炽灯泡)的应用中通常不是期望的。 Application of such a beam distributed in a solid state light bulb or intended to replace conventional lamps having better omnidirectional beam pattern (such as a conventional incandescent bulb) is generally not desirable. 虽然可能将LED光源或封装件以三维布置安装, 但这种布置的制造通常比较困难且昂贵。 While the LED light source may be a three-dimensional package or mounting arrangement, but this arrangement is usually more difficult and expensive to manufacture.

发明内容 SUMMARY

[0015] 本发明提供灯及灯泡,所述灯及灯泡大体上包括以下的不同组合和布置:光源、一种或多种波长转换材料、相对于该光源隔开地定位或定位于远端的多个区域或层、及单独漫射(diffusing,扩散)层。 [0015] The present invention provides a lamp bulb and the lamp bulb and substantially comprising different combinations and arrangements: a light source, one or more wavelength converting material positioned spaced apart or positioned relative to the light source to the distal end of the a plurality of layers or regions, and the diffusion alone (diffusing, diffusion) layer. 此布置允许制造有效、可靠且节省成本的灯及灯泡,且甚至在使用由LED的共平面布置组成的光源的情况下,也可提供基本上全向发射图案。 This arrangement allows the manufacture of the case where the efficient, reliable and cost-effective and light bulbs, and even in a LED light source is composed of a coplanar arrangement may also be provided a substantially omnidirectional radiation pattern. 另外,此布置允许当灯不照明时为了美观而遮掩或隐蔽这种转换区域或层的外观。 Further, this arrangement allows the light when the illumination is not masked or hidden for aesthetic appearance of such regions or layers of the converter. 本发明的各种实施例可用以解决在制造适于直接替换传统白炽灯泡的灯或灯泡的过程中的与利用有效固态光源(诸如,LED)相关联的许多困难。 May be used to resolve the manufacturing process is adapted to directly replace the traditional incandescent bulbs or light bulbs in the effective use solid state light source (such as an, LED) many difficulties of various embodiments of the present invention is associated. 本发明的实施例可经布置以适应所公认的标准大小的轮廓(诸如,属于常用灯(诸如,白炽灯泡)的轮廓),藉此促进直接替换这种灯泡。 Embodiments of the present invention may be arranged to accommodate a standard size contour recognized (such as a a common lamp (such as an incandescent bulb) of the profile), thereby facilitating direct replacement of such lamps.

[0016] 本发明的实施例还可包括具有位于该灯光源的远端的转换材料的各种布置,且可提供在该转换材料及该光源之上的漫射器,其中这种漫射器将来自该灯的光源和/或转换材料的光分散成一所需图案,诸如在视角范围内几乎均匀的颜色和/或强度。 [0016] Embodiments of the invention may further comprise various arrangements conversion material having a distal end of the light source, and may provide a diffuser on the light source and the conversion material, wherein such a diffuser and to / from the light source or light conversion material is dispersed into a desired pattern, such as in the range of viewing angles nearly uniform color and / or intensity.

[0017] 该漫射器的性质(比如,几何形状、散射层的散射性质、表面粗糙度或平滑度,及该等散射层性质的空间分布)可用以控制各种灯性质,比如随视角而变的颜色均匀性及光强度分布。 [0017] The properties of the diffuser (e.g., the geometry of the scattering properties of the scattering layer, the surface roughness or smoothness space, the nature and distribution of such scattering layer) can be used to control various properties of the lamp, such as with a viewing angle color uniformity and distribution of light intensity increases. 该漫射器的几何形状及其他方面可以许多不同方式用以修改光束分布。 The diffuser geometry and other aspects may be many different ways to modify the beam profile. 例如,藉由将漫射器组件的"灯泡"部分延伸至其他灯特征(比如,散热器部分)的轮廓之外,使得可自该灯后面看到该漫射器,从而可将额外光引导至相对于该灯的竖直轴大于90°的角度。 Outside example, by the "light bulb" section of the diffuser assembly extends to other lamp characteristics (for example, radiator portion) of the profile, so that the lamp can be seen from the rear of the diffuser, so that light can be guided additionally with respect to the vertical axis of the lamp is greater than the angle of 90 °. 用以散射光的颗粒的性质及甚至灯泡及散射膜表面的平滑度也可对给定漫射器几何形状的发射分布具有强烈的影响。 Properties of the particles to scatter light and even bulbs and flatness of the film surface scattering may also have a strong effect on the distribution of emission for a given diffuser geometry.

[0018] 通过具有在该光源的远端的转换材料及漫射器,可将升高的电信号施加至该光源,此可导致增加的光输出但也可使光源在较高温度下操作。 [0018] By having the distal end of the light source and the diffuser conversion material, the electrical signal may be applied to increase the light source, which may result in an increased light output, but also allows operation at a higher temperature source. 该光源与转换材料之间的距离减少了该光源内产生的热向磷光体或转换层的传递。 A distance between the light source and the conversion material to reduce heat transfer or conversion phosphor layer generated within the light source. 此维持高转换效率及可靠性,同时使小芯片计数成为可能,从而导致较低制造成本。 This maintained high conversion efficiency and reliability while making it possible to count the small chip, resulting in lower manufacturing costs. 一些实施例也可包括允许与转换相关的热有效传导离开远端转换材料的特征。 Some embodiments may also include allowing the heat associated with the conversion away from the distal end of the conductive features effective conversion material. 这种漫射器及转换材料可具有不同形状,且在一些实施例中,该两者的几何形状可协作以提供所需灯发射图案或均匀性。 Such conversion and diffuser material may have different shapes, and in some embodiments, both the geometry may cooperate to provide a desired light radiation pattern and uniformity.

[0098] 接合有红色和蓝色LED芯片的传统灯可经受在不同操作温度及调光下的颜色不稳定性。 [0098] engagement with red and blue LED chips may be subjected to conventional lamp without color stability at different operating temperatures and dimming. 此可由于红色和蓝色LED在不同温度及操作功率(电流/电压)下的不同行为以及随着时间的不同操作特性。 This may be due to the different behavior of red and blue at different temperatures and the LED operating power (current / voltage) and time with different operating characteristics. 此效应可通过实施主动控制系统来稍微减轻,该主动控制系统可增加整个灯的成本及复杂性。 This effect can be somewhat alleviated by active control system embodiments, the active control system may increase the cost and complexity of the entire lamp. 根据本发明的不同实施例可通过使具有相同类型的发光器的光源与远端磷光体载体组合来解决此问题,该远端磷光体载体可包括多层磷光体,该多层磷光体通过本文中所公开的热耗散布置而维持相对较冷。 According to various embodiments of the present invention can solve this problem by making the light emission having the same type of source in combination with the distal end of the carrier phosphor, the phosphor of the distal end of the support may include multiple layers of phosphor, the phosphor multilayer herein by heat dissipation arrangement as disclosed maintained relatively cool. 在一些实施例中,远端磷光体载体可吸收来自发光器的光且可重新发射不同颜色的光,同时仍具有磷光体的操作温度减少时的效率及可靠性。 In some embodiments, the distal end of the phosphor carrier can absorb light from the light emitter and may re-emit light of different colors, while still having the efficiency and reliability of the operating temperature of the phosphor is reduced.

[0099] 磷光体元件与LED的隔开提供了增加的优点:更容易且更一致的颜色分选。 [0099] The phosphor elements provides the added advantage of spaced LED: easier and more consistent color sorting. 此可以许多种方式来达成。 This can be achieved in many ways. 可将来自各种分选等级的LED (例如,来自各种分选等级的蓝色LED)装配到一起以达成可用在不同灯中的基本上波长一致的激发源。 It may be an LED (e.g., from various levels of sorting blue LED) sorted from various grades available are assembled together to achieve the same wavelength of the excitation light source in substantially different. 这些激发源可接着与具有基本上相同的转换特性的磷光体载体组合以提供发射在所期望分选等级内的光的灯。 The excitation source with the phosphor carrier may then have substantially the same conversion characteristics in combination to provide the desired emission of light in the sorting grade lamp. 另外, 可制造多种磷光体载体,且可根据其不同转换特性来对该多种磷光体载体预先分选。 Further, carriers can be manufactured more phosphors, and may be pre-sorting of the plurality of carriers according to their different phosphor conversion characteristics. 不同磷光体载体可与发射不同特性的光源组合以提供发射在目标颜色分选等级内的光的灯。 Different combinations of phosphors vectors may emit light with different properties to provide a color sorting target emission light in the light level.

[0100] 根据本发明的一些灯也可通过用反射表面来环绕光源提供提高的发射效率。 [0100] emitting efficiency may also be provided by using reflective surfaces surrounding the light source lamp in accordance with some of the present invention. 这通过将从转换材料重新发射的多数光往回向光源反射而导致增强的光子再循环。 This is accomplished by converting most of the material from the re-emitted light reflected back to the light source and result in enhanced photon recycling. 为了进一步增强效率且提供所要发射分布,磷光层、载体层或漫射器的表面可为平滑或散射的。 To further enhance the emission efficiency, and provide the desired distribution, the surface of the phosphor layer, the carrier layer or diffuser may be smooth or scattered. 在一些实施例中,载体层及漫射器的内表面可以是光学平滑的以促进全内反射行为,该全内反射行为减少自磷光层向后引导的光(向下转换(downconverted)的光或散射光)的量。 In some embodiments, the inner surface of the carrier layer and the optical diffuser may be smooth to facilitate total internal reflection behavior, the behavior of the total internal reflection of light from the phosphor layer to reduce light directed rearwardly (downwardly converted (downconverted) of or the amount of scattered light). 这减少了可由灯的LED芯片、相关联基板或灯内部的其他非理想反射表面吸收的向后发射的光的量。 This reduces the amount of light emitted rearwardly over other non-reflective surface of the LED chip, substrate, or the associated lamp inside the lamp may be absorbed.

[0 1 M]当来自光源58的光被磷光层66中的磷光体吸收时,光在各向同性方向上被重新发射,其中约50%的光向前发射且50%的光向后发射至空腔54中。 [0 1 M] when the light from the light source 58 is absorbed by the phosphor in the phosphor layer 66, the light is re-emitted isotropically in the direction in which about 50% of the light emitted forwardly and rearwardly emitted light of 50% into the cavity 54. 在具有保形磷光层的先前LED中,向后发出的光的大部分可被引导回至LED中,且光逃逸的可能性受LED结构的提取效率限制。 Conformal phosphor layer having an LED previously, most of the light emitted rearwardly may be directed back to the LED, and the possibility of escape of light extraction efficiency of the LED-receiving structure limits. 对于一些LED,提取效率可为约70%,因此自转换材料引导回至LED中的光中的一百分比可能损失。 For some LED, extraction efficiency may be about 70%, thus converting the material from the guide back to a percentage of the LED light may be lost. 在根据本发明的具有远端磷光体布置的灯中,LED位于空腔54的底部处的平台56上,向后的磷光体光中的较高百分比的光撞击空腔的表面而非LED。 In lamps having a distal end disposed of the phosphor according to the present invention, LED 56 is located on the platform at the bottom of the cavity 54, a higher percentage of light back in the phosphor light strikes the surface of the cavity rather than LED. 对这些表面涂布有反射层53增加了反射回至磷光层66 (在该磷光层处,光可自灯发射)中的光的百分比。 A reflective layer 53 to increase the percentage of light reflected back (in the phosphor layer, the light may be emitted from the lamp) in the phosphor layer 66 is applied to these surfaces. 这些反射层53允许光学腔使光子有效地再循环,且增加灯的发射效率。 The reflective layer 53 allows the optical cavity photons efficiently recycled, and increase the emission efficiency of the lamp. 应理解,反射层可包括许多不同材料及结构,包括但不限于反射金属或多层反射结构(诸如,分布式Bragg反射器)。 It should be understood, the reflective layer may comprise many different materials and structures, including, but not limited to, a metal or a reflective multilayer reflection structure (such as a distributed Bragg reflector). 在不具有光学腔的实施例中,也可包括在LED周围的反射层。 In an embodiment without an optical cavity, it may also include a reflective layer around the LED's.

[0148] 可使用不同的已知方法或材料(诸如,导热结合材料或热油脂)将磷光体载体62安装及结合于空腔54中的开口之上。 [0148] using different known methods or materials (such as thermal grease or thermally conductive bonding material) The phosphor carrier 62 is mounted over the cavity 54 and bound an opening. 传统的导热油脂可含有诸如氧化铍及氮化铝的陶瓷材料、或诸如胶体银的金属颗粒。 Traditional thermal grease may contain a ceramic material such as beryllium oxide and aluminum nitride, or metal particles such as colloidal silver. 在其他实施例中,可使用导热器件(诸如,夹紧机构、螺钉或热粘着剂)将磷光体载体安装于开口之上,从而将磷光体载体62紧紧地保持至散热器结构, 以使热导率最大化。 In other embodiments, the thermally conductive device may be used (such as a clamping mechanism, adhesive or thermal screw) the phosphor carrier mounted over the opening, so that the phosphor 62 is held tightly to the support structure of the heat sink, so that thermal conductivity is maximized. 在一个实施例中,使用具有约lOOwii的厚度及k = 0.2W/mk的热导率的热油脂层。 In one embodiment, having a thickness of about lOOwii and k = 0.2W / mk in thermal conductivity of the thermal grease layer. 此布置提供用于使热自磷光层66耗散的有效导热路径。 This arrangement provides for effective thermal conductivity of the thermal path from the phosphor layer 66 is dissipated. 如上文所提及,可提供无空腔的不同灯实施例,且除了在空腔的开口之上外,磷光体载体也可以许多不同方式来安装。 As mentioned above, the cavity can be provided without the lamp various embodiments, and in addition to over the opening of the cavity, the phosphor carrier can be mounted in many different ways.

[0149] 在灯50的操作期间,磷光体转换加热集中于磷光层66中,诸如集中于磷光层66的中心中,其中大多数LED光在磷光层66的中心撞击磷光体载体62且穿过磷光体载体62。 [0149] During operation of the lamp 50, focused on phosphor converted phosphor layer 66 is heated, such as concentrated in the center of the phosphor layer 66, most of LED light strikes the phosphor carrier at the center of the phosphor layer 66 and through 62 phosphor carrier 62. 载体层64的导热性质使此热在横向上朝向磷光体载体62的边缘散布,如由第一热流70示出的。 Thermally conductive nature of the carrier layer 64 so that this heat carrier towards the edge of the phosphor 62 dispersed in the lateral direction, as shown by the first heat flow 70. 在所述边缘处,热穿过热油脂层且进入散热器结构52中,如通过第二热流72示出的,在散热器结构52中,热可有效率地耗散至环境中。 At the edge, through the thermal grease layer and into the heat sink structure 52, as illustrated by the second heat flow 72, the structure of the radiator 52, the heat can be efficiently dissipated to the environment.

[0150] 如上文所论述,在灯50中,平台56与散热器结构52可热连接或耦接。 [0150] As discussed above, in the lamp 50, the platform 56 and heat sink structure 52 may be thermally connected or coupled. 此耦接布置导致磷光体载体62与光源58至少部分地共享用于耗散热的导热路径。 This coupling arrangement causes the phosphor 62 and the light source carrier 58 at least partially share a heat conduction path to dissipate heat. 来自光源58的穿过平台56的热(如由第三热流74示出的)也可散布至散热器结构52。 Heat from the light source 58 passes through the platform 56 (as shown by the third heat flux of 74) may also be dispersed to the heat sink 52 structure. 自磷光体载体62流入至散热器结构52中的热也可流入至平台56中。 Since the phosphor carrier 62 flows into the heat sink structure 52 also flows to the platform 56. 如下文进一步描述,在其他实施例中,磷光体载体62和光源54可具有用于耗散热的单独的导热路径,其中这些单独的路径被称作"解耦"。 As described further below, in other embodiments, the phosphor 62 and the light source carrier 54 may have a separate heat conduction path for dissipating heat, wherein the individual paths are referred to as "decoupling."

[0151] 应理解,除了图4中所示的实施例之外,磷光体载体可以许多不同方式来布置。 [0151] It should be understood, in addition to the embodiment illustrated in FIG. 4, the phosphor carrier can be arranged in many different ways. 磷光层可在载体层的任一表面上或可混合于载体层中。 A phosphor layer may be on either surface layer or the carrier may be mixed in the carrier layer. 磷光体载体也可包括散射层,所述散射层可包括于磷光层或载体层上或混合于磷光层或载体层中。 The phosphor carrier may also include a scattering layer, the scattering layer may be included on the phosphor layer or the carrier layer or carrier layer or mixed in the phosphor layer. 同样应理解,磷光体及散射层可覆盖小于载体层的表面,且在一些实施例中,转换层及散射层可在不同区域中具有不同浓度。 It should also be appreciated that, and the phosphor layer may cover the surface of the scattering layer is less than the carrier, and in some embodiments, converting layer and the scattering layer may have different concentrations in different areas. 同样应理解,磷光体载体可具有不同粗糙度或形状的表面以增强透过磷光体载体的发射。 It should also be appreciated that the phosphor carrier may have a different surface roughness or shaped to enhance the emission through the phosphor carrier.

[0152]如上文所提及,漫射器被布置成将来自磷光体载体和LED的光分散成所期望的灯发射图案,且可具有许多不同形状及大小。 [0152] As mentioned above, the diffuser is arranged to support from the phosphor and LED light is dispersed into a desired light emission pattern, and may have many different shapes and sizes. 在一些实施例中,漫射器也可布置于磷光体载体之上,以当灯不发光时遮掩磷光体载体。 In some embodiments, the diffuser may be disposed over the phosphor carrier, to when the lamp is not emitting phosphor cover carrier. 漫射器可具有用于赋予基本上白色外观的材料,以当灯不发光时赋予灯泡白色外观。 Diffuser material may have a substantially white appearance is imparted to the lamp when the lamp is not emitting white appearance imparting.

[015;3] 漫射器的至少四个属性或特性可用于控制灯50的输出光束特性。 [015; 3] at least four properties or characteristics of the diffuser may be used to output beam characteristics of the lamp 50 is controlled. 第一个属性或特性为独立于磷光层几何形状的漫射器几何形状。 The first property or characteristic of the phosphor layer is independent of the geometry of the diffuser geometry. 第二个属性或特性为关于磷光层几何形状的漫射器几何形状。 The second property or characteristic of a phosphor layer on a diffuser geometry geometry. 第三个属性或特性为漫射器散射性质,包括散射层的性质及漫射器表面的平滑度/粗糙度。 The third property or characteristic to diffuse scatter properties including smoothness / roughness of the surface of the diffuser and the nature of the scattering layer. 第四个属性或特性为表面上的漫射器的分布(诸如,散射的有意不均匀性)。 The fourth attribute or characteristic of the distribution on the surface of a diffuser (such as unevenness intentionally scattered). 这些属性允许控制(例如)轴向发射光相对于"侧向"发射光(~90°)、以及还相对于"高角度"(>~130°)的比率。 These properties allow control (e.g.) axially with respect to the emitted light "lateral" emits light (~ 90 °), and the ratio of "high-angle" (> ~ 130 °) with respect also. 根据磷光体载体及光源的几何形状及由磷光体载体及光源发出的光的图案,这些属性也可不同地应用。 The geometry of the light source and the phosphor carrier and the pattern of the light emitted by the phosphor carrier and the light source, these properties may be applied differently.

[0154] 对于二维磷光体载体和/或光源(诸如,图4中所示的那些)而言,所发出的光大体上为前向的(例如,朗伯)。 [0154] For two-dimensional vector phosphor and / or the light source (such as those shown in FIG. 4), the light is emitted substantially forward direction (e.g., Lambertian). 对于这些实施例,上文所列出的属性可提供将前向发射图案分散成宽广光束强度分布。 For these embodiments, the properties listed above may be provided to the emission pattern of the front wide dispersed beam intensity distribution. 第二属性及第四属性的变化可特别适用于由前向发射分布达成宽广光束全向发射。 Change in the second and fourth attribute attributes may be particularly applicable ago by reaching a broad distribution of the light beam to transmit omnidirectional transmission.

[0155] 对于三维磷光体载体(下文更详细描述)及三维光源,假设发射不被其他灯表面(诸如,散热器)阻挡,则所发出的光在大于90°时可已具有显著发射强度。 [0155] three-dimensional phosphor carrier (hereinafter described in more detail below), and three-dimensional light source, assumed emitter being the other surface of the lamp (such as a radiator) blocking, light is emitted may already have significant emission intensity greater than 90 °. 结果,上文所列出的漫射器属性可用于提供对来自磷光体载体及光源的光束分布的进一步调整或微调,使得其更接近地匹配所期望的输出光束强度、颜色均匀性、色点等。 As a result, the diffusion properties listed above may be used to further adjust or fine tune the distribution of the light beam from the light source and the phosphor of the carrier, such that the desired output beam intensity is more closely matched, color uniformity, color point Wait. 在一些实施例中,可调整光束分布以基本上匹配来自传统白炽灯泡的输出。 In some embodiments, the adjustable beam profile to substantially match the output from the traditional incandescent bulbs.

[0156] 就上文关于独立于磷光体几何形状的漫射器几何形状的第一属性而论,在光自漫射器表面均匀地发射的实施例中,相对于侧向(~90°)且相对于"高角度"(>~130°)被"向前"(轴向上或~0°)引导的光的量可很大程度上取决于当自那个角度观看时漫射器的横截面积。 [0156] respect to the properties described above for the first independent phosphor geometry diffuser geometry, in the embodiment of a light from the surface of the diffuser uniformly emitted with respect to the lateral (~ 90 °) with respect to the amount of light guided "high-angle" (> ~ 130 °) is "forward" (axially or ~ 0 °) may be highly dependent on the angle when viewed from the cross diffuser cross-sectional area. 图5示出了根据本发明的高窄漫射器80的一个实施例,其具有小的二维磷光体载体81。 FIG. 5 shows a high, narrow diffuser 80 according to the present embodiment of the invention, which the phosphor having a small two-dimensional carrier 81. 其特征在于,当沿第一视角82在轴向上观察时具有圆形区域,并且当沿第二视角84自侧面观察时具有较大区域。 Wherein a circular region having a first viewing angle 82 when viewed in the axial direction, and having a larger area along the second viewing angle 84 when viewed from the side. 相应地,此漫射器将具有相对于"侧向"发射的较低轴向光发射。 Accordingly, the diffuser having the low relative to the axial direction "lateral" emitted from the light emission. 若散热器或其他光阻挡特征存在于漫射器的底座处,则增加漫射器的高度可增加向后或高角度发射的量。 If a radiator or other light blocking characteristic is present in the base of the diffuser, the height may be increased to increase the amount of emitted backward or high-angle diffuser.

[0157] 图6示出了根据本发明的漫射器90的另一个实施例,其根据共平面光源和/或磷光体载体91的发射图案而特别适用于均匀全向发射。 [0157] FIG. 6 shows a diffuser according to another embodiment of the present invention in embodiment 90, based on co-planar light source emission pattern and / or a phosphor carrier 91 is particularly suitable for uniformly omnidirectional transmission. 漫射器90具有几乎均匀的球形几何形状,其提供当自所有角度观察时几乎恒定的横截面积。 Diffuser 90 having a substantially uniform spherical geometry, when all the time to provide an angle from an almost constant cross-sectional area was observed. 这促进了均匀或几乎全向的发射强度。 This facilitates uniform or nearly omnidirectional emission intensity.

[0158] 就第二属性一一相对于磷光体载体几何形状的漫射器几何形状而论,图7示出了漫射器100的另一个实施例,该漫射器被布置成特别适用于通常提供前向或朗伯发射图案的二维磷光体载体及共平面LED光源。 [0158] The second property to eleven with respect to the phosphor carrier geometry diffuser geometry of the connection, FIG. 7 shows an embodiment of the diffuser 100 of another embodiment, the diffuser is arranged to be particularly suitable for phosphor before dimensional vector or generally provide Lambertian emission pattern of the LED light source and coplanar. 漫射器100为长椭圆形的且具有窄颈102。 The diffuser 100 is oblong and has a narrow neck 102. 通过将光源和/或磷光体载体置放于漫射器100的底座处,原本自该源引导至前向角的光由于漫射器表面的散射性质而将会被"截获"且引导至较高角或侧向(~90°)。 By the light source and / or a phosphor is placed on the support base of the diffuser 100, the original source from which the light is guided to the front due to the scattering properties of the diffuser and the surface will be "intercepted" and the lead angle to a more high angle or lateral (~ 90 °). 三维光源及磷光体载体也可发生此效应,但可能具有较少效应。 Three-dimensional light source and the phosphor carrier. This effect can also occur, but may have less effect. 在这些三维实施例中的一些实施例中,漫射器可能不需要颈特征,而可更多地采用球体形状。 In some embodiments of these three embodiments, the diffuser neck feature may not be needed, but may employ more spherical shape.

[0159]图8为示出了来自二维磷光体载体及共平面LED光源的前向或朗伯发射图案112的一个实施例的曲线图110。 [0159] FIG. 8 is a diagram illustrating a forward or Lambertian emission from a two-dimensional pattern of the phosphor carrier and coplanar LED light source 112 is a graph showing an example of embodiment 110. 发射图案114示出了在由线112表示的发射图案穿过漫射器(如图7中所示出了)后的灯发射图案。 114 illustrates the emission pattern of the light emission pattern indicated by the line passing through the diffuser 112 (shown in Figure 7 a) emission pattern. 图案114示出了轴向上(~0°)的发射强度减少,而侧向上(~90°)的发射显著较高。 Pattern 114 shows the axial intensity of the emission (~ 0 °) is reduced, the emitted laterally (~ 90 °) is significantly higher. 此反映了与前向发射图案112相比更均匀的发射图案。 This reflects a more uniform radiation pattern as compared with the forward transmission pattern 112.

[0160] 就上文所列出的第三属性一一漫射器散射性质而论,漫射器的不同实施例可包括由不同材料(诸如,玻璃或塑料)制成的载体、及一个或多个散射膜、层或区域。 [0160] For the third attribute listed above eleven diffuser scattering properties concerned, different embodiments of the diffuser may comprise a carrier made of different materials (such as glass or plastic), and one or a plurality of scattering film, layer or region. 散射层可使用上文参照磷光层的沉积而描述的方法来沉积,且可包括颗粒的密集充填。 Scattering layer using methods described above with reference to deposition of the phosphor layer is deposited, and may include a dense packed particles. 散射颗粒也可被包括于粘合剂材料中,该粘合剂材料可与上文参考与磷光层一起使用的粘合剂描述的粘合剂材料相同。 The scattering particles may also be included in the binder material, the same adhesive material of the adhesive material may be used with reference to the above described phosphor layer of adhesive. 根据应用及所使用的材料,散射颗粒层可具有不同浓度的散射颗粒。 Depending on the application and the material used, the layer may have a different scattering particle concentration of scattering particles. 散射颗粒浓度的合适范围为0.01 %至0.2%,但应理解,浓度可更高或更低。 Suitable scattering particles concentration range of 0.01% to 0.2%, it is to be understood that the concentration may be higher or lower. 在一些实施例中,浓度可低至0.001%。 In some embodiments, concentrations as low as 0.001%. 同样应理解,散射颗粒层在不同区域中可具有不同浓度的散射颗粒。 It should also be understood that the layers may have different scattering particle concentration of scattering particles in different regions. 对于一些散射颗粒,可能存在由于较高浓度的吸收而产生的损失的增加。 For some scattering particles, there may be an increased loss due to the absorption of high concentration is generated. 因此,可选择散射颗粒的浓度以便维持可接受损失数字,而同时分散光以提供所期望的发射图案。 Thus, the concentration of scattering particles be selected so as to maintain an acceptable loss figure, while the dispersion to provide the desired light emission pattern.

[0161] 散射颗粒可包括许多不同材料,包括但不限于: [0161] The scattering particles may comprise many different materials, including but not limited to:

[0180] 可使用呈各种材料组合或相同材料的不同形式的组合的一种以上散射材料来达成特定散射效应。 [0180] can be used to achieve a particular scattering effect of the scattering material form one or more combinations of various materials or combinations of different forms of the same material.

[0181] 散射层可位于漫射器的内表面、外表面上,或可混合于载体中。 [0181] scattering layer may be the inner surface of the diffuser, an outer surface, or may be mixed with a carrier. 散射层的载体的表面可光学平滑或粗糙。 Surface of the carrier of the scattering layer may be optically smooth or rough. 散射层可由膜或颗粒构成,诸如粘附至载体的表面的二氧化硅或高岭土颗粒,其中颗粒之间具有空气。 Scattering layer may be composed of a film or particles, such as silica or kaolin particles adhered to the surface of the carrier, wherein an air between the particles. 散射层也可包括粘合剂基质层(诸如,二氧化硅、铝等的膜)中的颗粒、硅中的颗粒。 It may also include a scattering layer (film such as silicon dioxide, aluminum or the like) in the pressure-sensitive adhesive matrix layer of particles, the silicon particles. 该层可喷涂至载体的内表面或外表面上,或载体自身可含有散射颗粒。 This layer may be sprayed to the inner surface or outer surface of the support or carrier itself may contain scattering particles. 可模制成漫射器的形状的散射膜的一个实例为可购自Fus ionOptix,Inc.的膜。 Examples of a diffusion film molded into a shape of the diffuser film is commercially available from Fus ionOptix, Inc. Of.

[0182] 大体上,散射材料或颗粒的特征可在于入射于颗粒上的光自其原始路线被重新引导的程度。 [0182] In general, characteristics or particle scattering material may be characterized by the degree of light incident on the particles from its original route to be redirected. 在各个颗粒的情况下,较大颗粒将倾向于米氏(Mie)散射,从而导致光的方向的相对较少改变。 In the case of individual particles, larger particles will tend to Michaelis (the Mie) scattering, resulting in a relatively small change of direction of the light. 较小颗粒倾向于瑞利(Reyleigh)散射,从而导致在与颗粒相互作用之后光的方向的大改变及光的基本上均匀或各向同性的分布。 Smaller particles tend to Rayleigh (Reyleigh) scattering, resulting after interaction with the particles is substantially uniform or isotropic light and a large change in the direction of light distribution. 由颗粒构成的膜可以类似方式来表现。 Particles composed of a film can be expressed in a similar manner. 可使用各种各样的表面特征和/或散射颗粒,其效果由吸收(愈低愈好)及与周围基质/ 环境的折射率差异(较大差异产生更有效的散射)来判定。 It may be determined using a variety of surface features and / or scattering particles, which results from the absorption (the smaller the better) and (scattering results in more efficient large difference) and the difference in refractive index surrounding matrix / environment.

[0183] 漫射器表面的平滑度可由于全内反射(TIR)效应而用于影响向后朝向磷光体载体的光源引导的光的量。 [0183] smoothness of the surface of the diffuser may be due to total internal reflection (TIR) ​​effects influence the amount of light back towards the source of the phosphor support for the guide. 平滑的内表面可导致TIR且使原本朝向该源引导的光被重新引导。 Smooth inner surface and can lead to TIR the light source directed towards the original redirected. 相对照地,被粗糙化的内表面不展现此效应。 In contrast, the roughened inner surface does not exhibit this effect. 被向后朝向其他内部灯表面的源重新引导的光可被吸收,从而导致减少的灯效率。 The redirected light back toward the other internal surface of the source light may be absorbed, resulting in reduced efficiency of the lamp. 向后朝向磷光层散射的光可导致增加的向下转换(downconversion)的量且因此由于漫射器而导致灯的色温或色点的偏移。 Scattered back towards the phosphor layer may result in an increased amount of light down conversion (downconversion) and thus the offset caused due diffuser color temperature or color point of the lamp. 然而,高程度的反向散射(backscattering,后向散射)也可通过产生"光箱"效应而提高均勾性,在该"灯光箱"效应中光在漫射器内部散射,从而导致漫射器表面上的更均匀分布、及灯发出的光束分布的更均匀的色点及强度分布。 However, a high degree of backscattering (Backscattering, backscatter) may also be improved by each of the hooks have a "light box" effect, light scattering inside the diffuser, thereby causing the diffusion "light box" effect of more evenly distributed on the surface, and a light beam emitted from a more uniform distribution of the color point and intensity distribution.

[0184] 对于第四属性一一表面上的漫射器散射分布,漫射器表面上的散射性质的均匀性可用以控制在特定区域中自表面发出的光的量且因此控制所形成的光束分布。 [0184] For the fourth attribute eleven diffuser scattering distribution on the surface, the uniformity of the amount of light from the surface may be used to control the emitted scattering properties in a specific area on the surface of the diffuser and thus controlling the beam formed distributed. 此可尤其可用在与其他属性(诸如在分散器中具有颈特征的图7中所示的第二个属性)组合时。 This may be particularly useful when the other properties (such as a neck FIG feature in the dispersion vessel 7 shown in the second property) in combination. 通过在展现二维磷光体载体及共平面LED光源的发射的灯中利用具有窄颈区域的长椭圆形漫射器及粗糙的高度散射(瑞利或各向同性)内部粗糙表面膜,可在侧向上引导光的显著部分,如图8所示。 By using a diffuser having an oblong narrow neck region and the height of the roughening scattering (Rayleigh or isotropic) exhibit emission in the phosphor carrier and the two-dimensional co-planar LED light source lamp inside a rough surface film, can be significant portion of the guide light on the side, as shown in FIG. 该效应可通过增加透射通过漫射器的颈区域中的散射膜的光的量而放大。 This effect can be amplified by increasing the amount of light transmitted in the neck area of ​​the diffuser film by scattering. 若由磷光体载体及光源发出的光的显著部分与散射层相互作用,则光将在漫射器的本体内四处反弹,此可增强均匀发射。 If a significant portion of the scattering layer of the light emitted by the phosphor carrier and the light source interaction, the four light will bounce in the body of the diffuser, which may enhance the uniformity of emission. 通过形成散射膜较为透明的区域(诸如,通过使这种区域中的散射膜更薄或更平滑),有可能增加离开那个表面的相对强度。 Forming a film by scattering a more transparent region (such as by scattering or smoother thinner film in this region), it is possible to increase the relative strength of the surface away. 在图7中所示的实施例中,离开颈区域进入侧向光束方向的光的量可通过在那个区域中具有更薄或更平滑的散射层而增加。 The amount of light in the embodiment shown in Figure 7, leaving the neck region into the lateral direction of the beam scattering layer may have a smoother or thinner in that region is increased by.

[0185] 这种方式仅为这种属性可以不同方式组合以提供所要发射图案的方式中的一些。 [0185] In this manner this property can only be combined in different ways to provide some manner of emission pattern. 该组合可导致可提供除了全向图案之外的许多不同灯发射图案的许多不同形状。 The combination may result in many different shapes may be provided in addition to the whole number of different emission patterns of light outside the pattern. 图9至12 示出了可与根据本发明的灯中的二维载体磷光体(及如下文所描述的三维磷光体)一起使用的一些附加漫射器形状及大小。 9 to 12 shows a two-dimensional vector with the phosphors in the lamp of the present invention (and three phosphors as described below) of some additional diffusers for use with shape and size. 图9示出了与图7中所示的实施例类似的且大体上为具有较短的窄颈部分的球体形状的漫射器130。 FIG 9 shows the embodiment shown in FIG. 7 and is substantially similar to a diffuser 130 having a spherical shape of a short narrow neck portion. 图9示出了漫射器130的一个实施例的尺寸,其中也示出了图10至12中的漫射器的尺寸。 Figure 9 illustrates the size of a diffuser 130 according to an embodiment, which also illustrates the dimensions of FIGS. 10 to 12 of the diffuser. 图10示出了具有较短颈且保留其大部分球体形状的漫射器140的另一个实施例。 FIG 10 shows another having a shorter neck and retain their spherical shape of the diffuser 140 in most embodiments. 图11示出了不具有颈区域但保留其大部分球体形状的漫射器150的另一个实施例。 FIG 11 shows a region of the neck, but having no other diffuser 150 retains its spherical shape most embodiments. 图12示出了漫射器160的又一个实施例,其中漫射器更多地包括半球形形状。 FIG. 12 illustrates yet another embodiment of the diffuser 160, wherein diffuser comprises a more hemispherical shape. 这种形状给发光器提供不同图案及不同等级的效率,如下文所描述且附图中所示出的。 This shape provides a light emission efficiency of different patterns and different levels, as described below and in the drawings shown. 这种形状为漫射器可采取的数不尽的其他形状,且一些额外形状为蘑菇形、子弹形、 圆柱形、蛋形、椭圆形等。 Other shapes such as a diffuser may take the form of endless, and some additional mushroom shape, a bullet-shaped, cylindrical, egg-shaped, oval and the like. 在其他实施例中,漫射器可采取以下形状:其在底座处较宽且至少经由移离底座的一部分而变窄。 In other embodiments, the diffuser may take the following form: at least via its broader and narrower move away from the base portion at the base. 这种实施例可采取底部宽于顶部的形状。 Such embodiments may take the shape of a wide bottom to top.

[0196] 如上文所提及,灯300的特征中的一些之间的空间可被当作混合腔室,其中光源306与磷光体载体308之间的空间包括第一光混合腔室。 [0196] As mentioned above, some characteristics of the space between the lamp 300 may be used as the mixing chamber, wherein a space 308 between the source 306 comprises a first carrier with the phosphor light mixing chamber. 磷光体载体308与漫射器310之间的空间可包括一第二光混合腔室,其中该混合腔室促进该灯的均匀的颜色及强度发射。 Phosphor carrier 308 and the space between the diffuser 310 may comprise a second light mixing chamber, wherein the mixing chamber to promote a uniform color and intensity of the emitted light. 相同情况可适用于下文的具有不同形状的磷光体载体及漫射器的实施例。 Same applied to the following case where the phosphor carrier and the diffuser having different shapes embodiment. 在其他实施例中,可包括形成附加混合腔室的附加漫射器和/或磷光体载体,且漫射器和/或磷光体载体可以不同次序来布置。 In other embodiments, the diffuser may additionally comprise forming an additional mixing chamber and / or a phosphor carrier and the diffuser and / or a phosphor carrier may be arranged in a different order.

[0197] 根据本发明的不同灯实施例可具有许多不同形状及大小。 [0197] According to various embodiments of the lamp according to the present invention may have many different shapes and sizes. 图31示出了根据本发明的灯320的另一个实施例,其类似于灯300,且类似地包括散热器结构325中的光学腔322,其中光源324安装至光学腔322中的平台326。 FIG 31 shows a lamp 320 according to another embodiment of the present invention, which is similar to the lamp 300, and similarly includes optical cavity structure 325 of the heat sink 322, wherein the light source 324 is mounted to the platform 326 of the optical cavity 322. 类似上文,散热器结构无需具有光学腔,且光源可提供于除了散热器结构之外的其他结构上。 Likewise the above, the heat sink having a structure without an optical cavity, and the light source may be provided on other structures other than the structure of the heat sink. 这种结构可包括具有光源的平面表面或基座。 Such structure may include a base having a planar surface or a light source. 磷光体载体328通过热连接件而安装于空腔开口之上。 Phosphor support member 328 is connected by heat and attached to the top of the cavity opening. 灯320还包括安装至散热器结构325、在光学腔之上的漫射器圆顶330。 Lamp 320 further includes a mounting structure 325 to the heat sink, the diffuser dome 330 above the optical cavity. 漫射器圆顶可由与上文所描述及图15中所示的漫射器圆顶310相同的材料制成,但在此实施例中,圆顶300经成形为椭圆形或蛋形的以提供不同的灯发射图案,同时仍遮掩来自磷光体载体328中的磷光体的颜色。 Diffuser dome and the diffuser dome may be described above and shown in FIG. 15 310 made of the same material, but in this embodiment, the dome 300 is shaped as an oval or egg-shaped to provide different light emission patterns, while still mask the color from the phosphor in the phosphor 328 of the carrier. 同样请注意,散热器结构325与平台326为热解耦的。 Also please note that the heat sink structure 325 and 326 is thermally decoupled from the platform. 即,平台326与散热器结构之间存在空间,使得其不共享用于耗散热的热路径。 That is, there is a space between the platform 326 and the heat sink structure, so that it does not share a thermal path to dissipate heat. 如上文所提及,与不具有解耦的热路径的灯相比,此可提供提高的自磷光体载体的热耗散。 As mentioned above, the heat, as compared with a lamp without the thermal decoupling paths, which can provide improved dissipation from the phosphor carrier. 灯300还包括用于安装至Edison螺纹座的螺纹部分332。 Edison lamp 300 further includes a threaded base for attachment to a threaded portion 332.

[0198] 图32至34示出了根据本发明的灯340的另一个实施例,其类似于图31中所示的灯320。 [0198] FIGS 32-34 illustrate another embodiment of the present invention, a lamp 340, a lamp 320 which is similar to that shown in FIG. 31. 灯340包括具有光学腔342的散热器结构345 (其中光学腔342具有在平台346上的光源344),及在光学腔之上的磷光体载体348。 Lamp 340 comprises an optical cavity 342 of the heat sink 345 (which optical cavity 342 has a light source 344 on the platform 346), and a phosphor on a carrier 348 of the optical cavity. 灯340进一步包括一螺纹部分352。 Lamp 340 further includes a threaded portion 352. 灯340还包括漫射器圆顶350,但在此实施例中,漫射器圆顶在顶部经平坦化以提供所要发射图案,同时仍遮掩磷光体的颜色。 Further comprising a light diffuser dome 340 350, but in this embodiment, the diffuser dome at the top of the planarized to provide a desired emission pattern, at the same time still mask the color phosphors embodiment.

[0199] 灯340还包括自光源344起的在光源344与散热器结构345之间的界面层354。 [0199] Light from the light source 340 further comprises an interface layer 344 from the light source 354 between 344 and 345 of the heat sink structure. 在一些实施例中,界面层可包括热绝缘材料,且光源344可具有促进热自发光器耗散至光源的基板的边缘的特征。 In some embodiments, the interfacial layer may include a heat insulating material and having a light source 344 may facilitate heat dissipation from the edge of the substrate to the light emitter of the light source features. 此情形可促进热耗散至散热器结构345的外边缘,在这种外边缘处热可经由散热鳍片耗散。 This may facilitate heat dissipation to the outer edge of the heat sink structure 345, in which the outer edge of the heat dissipation via the heat dissipating fins may be. 在其他实施例中,界面层354可为电绝缘的,以使散热器结构345与光源344电隔离。 In other embodiments, the interface layer 354 may be an electrically insulating heat sink structure 345 so that the light source 344 is electrically isolated. 可接着进行至光源的顶面的电连接。 It may then be electrically connected to the light source of the top surface.

[0200] 在上述实施例中,磷光体载体为二维的(或平坦/平面),同时光源中的LED为共平面的。 [0200] In the above embodiment, the phosphor is a two-dimensional carrier (or flat / plane), while an LED light source are co-planar. 然而,应理解,在其他灯实施例中,磷光体载体可采用许多不同形状,包括不同的三维形状。 However, it should be appreciated that in other embodiments of the lamp, the phosphor carrier can take many different shapes, including different three-dimensional shapes. 术语"三维"意欲意谓除了如上述实施例中所示出了的平面之外的任何形状。 The term "three-dimensional" is intended to mean any shape other than a plane as shown in the above-described embodiment shown in FIG. 图35至38示出了根据本发明的三维磷光体载体的不同实施例,但应理解,这种磷光体载体也可采用许多其他形状。 FIGS. 35-38 illustrate three different embodiments of the phosphor carrier according to the invention, it is to be understood that such a phosphor carrier can also take many other shapes. 如上文所论述,当磷光体吸收并重新发射光时,其以各向同性方式发射, 使得三维磷光体载体用以转换来自光源的光且也分散来自光源的光。 As discussed above, when the phosphor absorbs and re-emits light, which is emitted in an isotropic manner, such that the three-dimensional support for the phosphor converted light from the light source and the light from the source is also dispersed. 类似上述漫射器,不同形状的三维载体层可以具有不同特性的发射图案来发射光,此部分视光源的发射图案而定。 Diffuser similar to the above, the three-dimensional shape of the carrier layer may have a different emission pattern to emit light of different characteristics, this emission pattern depending on the light source section. 可接着使漫射器与磷光体载体的发射匹配以提供所要灯发射图案。 Transmitter may then make matching with the phosphor diffuser support to provide the desired light emission pattern.

[0201]图35示出了半球形形状的磷光体载体354,该磷光体载体包括半球形载体355及磷光层356。 [0201] FIG. 35 shows a hemispherical shape of the phosphor carrier 354, the carrier comprises a semi-spherical phosphor carrier 355 and the phosphor layer 356. 半球形载体355可由与上文所描述的载体层相同的材料制成,且磷光层可由与上文所描述的磷光层相同的材料制成,且散射颗粒可如上文所描述地被包括于载体和磷光层中。 Carrier 355 may be manufactured in hemispherical shapes made with the same carrier layer material described above, and the phosphor layer with the phosphor layer may be the same as the above-described materials, and scattering particles as described above it may be included in a carrier and a phosphor layer.

[0202] 在此实施例中,将磷光层356示出为位于载体355的外表面上,但应理解,磷光层可位于载体的内层上、与载体混合、或以上三种情况的任何组合。 Any combination thereof [0202] In this embodiment, the phosphor layer 356 is shown on the outer surface of the carrier 355, it should be understood that the phosphor layer may be positioned on the inner carrier, mixed with a carrier, or three of the above . 在一些实施例中,在外表面上具有磷光层可使发射损失最小化。 In some embodiments, the outer surface of a phosphor layer emitting the loss can be minimized. 当发光器光被磷光层356吸收时,光全向发射,且一些光可向后发射并被诸如LED的灯元件吸收。 When the light emitting phosphor layer 356 is absorbed by the light-emitting omnidirectional and some light may be emitted back and the absorbent element such as an LED lamp. 磷光层356也可具有与半球形载体355不同的折射率,使得自磷光层向前发出的光可被自载体355的内表面反射返回。 Phosphor layer 356 may have a hemispherical support 355 with different refractive indices, such that light from the phosphor layer may be emitted forwardly from the inner reflective surface of the carrier 355 is returned. 此光也可由于被灯元件吸收而损失。 This light may be lost due to absorption of light elements. 在磷光层356位于载体355的外表面上的情况下,向前发出的光不需要穿过载体355且将不会由于反射而损失。 In the case of the carrier 355 on the outer surface of the phosphor layer 356, the light emitted forward through the carrier 355 need not and will not be lost due to reflection. 向后发出的光将碰到载体的顶部,在该顶部处至少一些光将反射回。 The light emitted rearwardly across the top of the carrier, at least some light will be reflected back at the top. 此布置导致来自磷光层356的被发射返回至载体中的光的减少,在载体中,光可被吸收。 This arrangement causes emitted from the phosphor layer 356 to reduce the return light in the carrier, the carrier, the light may be absorbed.

[0203] 可使用上文所描述的相同方法中的许多方法来沉积磷光层356。 [0203] Many methods may be used in the same manner as described above to the phosphor layer 356 is deposited. 在一些例子中,载体355的三维形状可能要求附加步骤或其他工艺以提供必要的覆盖。 In some examples, the three-dimensional shape of the carrier 355 may require additional steps or other process to provide the necessary coverage. 在喷涂溶剂-磷光体-粘合剂混合物的实施例中,可如上文所描述对载体加热,且可能需要多个喷嘴以提供在载体之上的所要覆盖(诸如,近似均匀覆盖)。 Spraying solvent - phosphor - Example of the binder mixture may be as described above for carrier heating and a plurality of nozzles may be needed to provide the support to be covered over (such as a near-uniform coverage). 在其他实施例中,可使用较少喷嘴,同时旋转载体以提供所要覆盖。 In other embodiments, fewer nozzles may be used, while rotating the carrier to provide the desired coverage. 类似上文,来自载体355的热可使溶剂蒸发且帮助固化粘合剂。 Likewise the above, the heat from the carrier 355 can help cure the adhesive and the solvent was evaporated.

[0204] 在另外的其他实施例中,可经由浸水工艺形成磷光层,藉此可在载体355的内表面或外表面上形成磷光层,但其特别适用于形成于内表面上。 [0204] In still other embodiments, the soaking process may be formed by phosphor layer, thereby forming a phosphor layer may be the inner or outer surface of the carrier 355, but it is particularly suitable for forming on the inner surface. 载体355可至少部分填充有黏附至载体的表面的磷光体混合物,或以其他方式使载体355接触磷光体混合物。 Carrier 355 may be at least partially filled with adhesive to the surface of the carrier of the phosphor blend, or otherwise contacting the carrier 355 phosphor mixture. 可接着自载体排出该混合物,从而在表面上留下磷光体混合物层,可接着使该磷光体混合物层固化。 The mixture may then be discharged from the carrier, leaving a mixture of the phosphor layer on the surface, it may then cause the phosphor blend layer is cured. 在一个实施例中,混合物可包括聚氧化乙烯(PE0)及磷光体。 In one embodiment, the mixture may include polyethylene oxide (PE0) and phosphor. 可填充载体且接着将载体排空,从而留下PE0-磷光体混合物层,可接着热固化该PE0-磷光体混合物层。 The carrier may be filled and then emptied carrier, leaving PE0- phosphor blend layer, which may then PE0- phosphor blend layer is thermally cured. PE0蒸发或被热驱散, 从而留下磷光层。 PE0 heat dissipated or evaporated, leaving the phosphor layer. 在一些实施例中,可涂覆粘合剂以进一步固定磷光层,而在其他实施例中,磷光体可保留而无粘合剂。 In some embodiments, the adhesive may be applied to further secure the phosphor layer, while in other embodiments, the phosphor can be retained without an adhesive.

[0205] 类似用以涂布平面载体层的工艺,这种工艺可用于三维载体中以涂覆可具有相同或不同的磷光体材料的多个磷光层。 [0205] Similar process used to coat the plane of the support layer, this process can be used for a plurality of phosphor layers applied to three-dimensional vector may have the same or a different phosphor material. 磷光层也可涂覆于载体的内部与外部两者上,且可具有在载体的不同区域中具有不同厚度的不同类型。 A phosphor layer may also be coated on both the interior and exterior of the carrier, and may have different types having different thicknesses in different areas of the carrier. 在另外的其他实施例中,可使用不同工艺,诸如,对载体涂布以磷光体材料薄片,其可热形成至载体。 In still other embodiments, different processes may be used, such as, on the carrier material coated with a phosphor sheet, which is heat-formed to a carrier.

[0206] 在利用载体355的灯中,发光器可布置于载体的底座处,以使得来自发光器的光向上发射且穿过载体355。 [0206] In use of the lamp support 355, the light emitter may be disposed at the base of the support, so that light emitted from the light emitter 355 upwards and through the carrier. 在一些实施例中,发光器可按大体上朗伯图案发光,且载体可帮助使光按更均匀图案分散。 In some embodiments, the light emitter may be substantially Lambertian emission patterns, and the carrier can help disperse the light according to a more uniform pattern.
