Higher power forms are intended for experimental or original equipment manufacturer (OEM) use.
现在一般公众通常能够得到更高功率的激光器。目前1W445nm激光器和0.5W405nm激光器的低廉价格使得它们广受欢迎。445nm蓝光以及特别是405nm紫光激光器具有人眼对其较不敏感的波长。在这些波长上的激光束具有被察觉到的低亮度，但是具有危害性的功率。Higher power lasers are now generally available to the general public. The current low prices of 1W445nm lasers and 0.5W405nm lasers make them popular. 445nm blue and especially 405nm violet lasers have wavelengths to which the human eye is less sensitive. Laser beams at these wavelengths have a perceived low brightness, but are of hazardous power.
然而，上述激光设备的使用限于实验或原始设备制造商(OEM)的用途，这是因为当上述激光器被用作激光指示器时它们的功率水平会造成安全隐患。所需要的是一种装置，其将上述激光器的用途扩展到实验或OEM用途之外，从而激光器的热衷者和这种设备的其他使用者能够从这些激光设备得到另外的效用。在该领域中还需要的是一种由固定的或便携的激光束生成装置生成低功率光照的装置，以节约功率和提供激光设备的多种用途，使得它们能以不同方式被使用，例如一种能够点火的一体化工具，以在紧急情况下提供照明和发信号。However, the use of such laser devices is limited to experimental or original equipment manufacturer (OEM) use because of the safety hazards posed by the power levels of such lasers when they are used as laser pointers.

发明详述Detailed description of the invention
特别地，本发明旨在激光到各种颜色的光的转换。当根据本发明的实施方式进行修改时，借助于转换器，激光器可以被转换为能以适于在黑夜或黑暗区域观看的白光以及各种彩色光进行照明的光。这种被转换的激光器如同便携的手电筒或普通灯(例如，灯泡)一样有用，并且其彩色光的形式也如同灯光表演中装饰性的固定或便携发光元件一样有用并能产生一系列的彩色光。In particular, the invention is directed to the conversion of laser light to light of various colors. When modified according to the embodiment of the present invention, by means of a converter, the laser can be converted into light capable of illuminating in white light suitable for viewing at night or in dark areas, as well as various colored lights. The converted lasers are as useful as portable flashlights or ordinary lamps (e.g., light bulbs) and in the form of colored light as decorative fixed or portable lighting elements in light shows and can produce a range of colored lights .
本发明的一个主要特征是借助于波长转换材料，例如安装到转换器设备上的荧光体，通过将一些激光输入转换为呈现白色的光输出来产生高效的照明。这种“白光”部分地由原始的源激光的光组成，但是额外地具有广谱的来自荧光体发光的其他波长。A key feature of the present invention is the generation of efficient illumination by converting some of the laser input into a light output that appears white by means of wavelength converting materials, such as phosphors mounted on the converter device. This "white light" consists in part of the light of the original source laser light, but additionally has a broad spectrum of other wavelengths from phosphor emission.
本发明的另一个特征是通过采用不同的荧光体或不同荧光体的混合来由激光输入产生彩色光。Another feature of the invention is to generate colored light from laser input by using different phosphors or a mixture of different phosphors.
总得来说，在本发明的转换后的便携式激光手电筒中有：(1)至少一个激光源，(2)用于激光束的至少一个反射器，(3)至少一个荧光体以及(4)至少一个输出光束聚焦装置。任何激光源都可以被用在本发明中，然而，优选地使用蓝色或紫色激光源，并且更优选地当产生白光时使用蓝色445nm激光器。In general, in the converted portable laser torch of the present invention there are: (1) at least one laser source, (2) at least one reflector for the laser beam, (3) at least one phosphor and (4) at least An output beam focusing device. Any laser source can be used in the present invention, however, preferably a blue or violet laser source is used, and more preferably a blue 445nm laser when white light is generated.
在本发明的实施方式中，激光束被反射到荧光体上。合适的反射器包括反射镜、反射镜阵列或衍射光学镜片。尽管这里详细说明了几种配置，但是现在参考优选的实施方式以及图1和2。在优选的实施方式中，激光器与用于将激光束转换为照明光的转换器同轴。该转换器由输出光反射器、具有顶部二向色涂层的玻璃基板、夹具、导热粘合剂、波长转换材料、2-轴透射衍射光栅、模块支持器，以及透明的窗口组成。In an embodiment of the present invention, the laser beam is reflected onto the phosphor. Suitable reflectors include mirrors, mirror arrays or diffractive optics. Although several configurations are described in detail herein, reference is now made to the preferred embodiment and FIGS. 1 and 2 . In a preferred embodiment, the laser is coaxial with the converter for converting the laser beam into illumination light. The converter consists of an output light reflector, a glass substrate with a top dichroic coating, a fixture, a thermally conductive adhesive, a wavelength conversion material, a 2-axis transmission diffraction grating, a module holder, and a transparent window.
在优选的实施方式中，光转换模块(图1中包括的参考编号1到6)安装在转换器外壳7内，转换器外壳7的外径螺纹优选地被设计为拧入通常可得到的便携式激光器中。透明的窗口8阻止灰尘和污垢的进入。In a preferred embodiment, the optical conversion modules (reference numbers 1 to 6 included in FIG. 1 ) are mounted within a converter housing 7 whose outer diameter threads are preferably designed to screw into commonly available portable in the laser. The transparent window 8 prevents the entry of dust and dirt.
现在参考输出光反射器1，其优选地是标准的铝或铜反射器，或施加到接收光的转换器表面的反射涂层。更优选地，输出光反射器1是在内部镀银的。Reference is now made to the output light reflector 1, which is preferably a standard aluminum or copper reflector, or a reflective coating applied to the surface of the converter that receives the light. More preferably, the output light reflector 1 is internally silvered.
玻璃基板2被二向色涂层涂覆以形成二向色反射镜。二向色涂层用于防止反射的光的浪费。为了产生其输出与照明光束的路径同轴的转换器，优选的方法是采用荧光体的后部照明。这样做，通常超过50％的射出的光将会被浪费掉，因为其大多是从被照明的那侧射出的。为了重获这些被浪费的光中的一些，二向色反射镜被用作荧光体/树脂的基板。优选地二向色反射镜被选择为在照明波长处(通常是445nm)具有低的反射率，并且对于长于照明波长的波长具有高的的反射率。二向色涂层可以位于与荧光体相同的一侧或者位于与荧光体相对的一侧。示例性二向色涂层包括多层五氧化二钽和二氧化硅或多层二氧化钛和二氧化硅。The glass substrate 2 is coated with a dichroic coating to form a dichroic mirror. Dichroic coatings are used to prevent the waste of reflected light. In order to create a converter whose output is coaxial with the path of the illumination beam, the preferred method is backlighting with phosphors. In doing so, typically more than 50% of the emitted light will be wasted since most of it is emitted from the side being illuminated. To recover some of this wasted light, dichroic mirrors are used as substrates for the phosphor/resin. Preferably the dichroic mirror is chosen to have a low reflectivity at the illumination wavelength (typically 445nm) and a high reflectivity for wavelengths longer than the illumination wavelength. The dichroic coating can be on the same side as the phosphor or on the side opposite the phosphor. Exemplary dichroic coatings include multiple layers of tantalum pentoxide and silicon dioxide or titanium dioxide and silicon dioxide.
二向色涂层的玻璃在本领域中是众所周知的并且能够在商业上从多种来源得到。为了形成特有的二向色涂层，不同金属(例如金或银)的多个超薄层；诸如钛、铬、铝、锆，或镁这些金属的氧化物；或硅在真空室中被电子束蒸发。接着，蒸汽在玻璃表面以结晶结构的形式凝结。有时会添加石英晶体的保护层。这种物理汽相沉积(PVD)涂层的其他变化形式也是可能的。最终的玻璃可以具有多达30到50层的这种金属，然而全部涂层的厚度大约是一英寸的百万分之30到35(约760到890nm)。所产生的涂层非常类似于宝石，并且通过精心地控制厚度，可以获得不同的颜色。达到二向色层的所有光等于反射的波长加上穿过二向色层的波长。Dichroic coated glasses are well known in the art and are commercially available from a variety of sources. To form the characteristic dichroic coating, multiple ultrathin layers of different metals such as gold or silver; oxides of metals such as titanium, chromium, aluminum, zirconium, or magnesium; Beam evaporation. The vapor then condenses on the glass surface in the form of crystalline structures. Sometimes a protective layer of quartz crystal is added. Other variations of this physical vapor deposition (PVD) coating are also possible. The final glass can have as many as 30 to 50 layers of this metal, yet the thickness of the total coating is about 30 to 35 millionths of an inch (about 760 to 890 nm). The resulting coating closely resembles gemstones, and by carefully controlling the thickness, different colors can be obtained. All light reaching the dichroic layer is equal to the reflected wavelength plus the wavelength passing through the dichroic layer.
玻璃基板2也由导热玻璃形成，导热玻璃例如能够从位于纽约州埃尔姆斯福德(Elmsford)的Schott North America公司得到的Schott Glass BK7。优选地，玻璃基板2被选择为具有比粘附到其的波长转换材料5更高的导热性。可选地，无掺杂的钇铝石榴石(YAG)，蓝宝石或金刚石可以被用作基板。The glass substrate 2 is also formed from a thermally conductive glass such as Schott Glass BK7 available from Schott North America, Inc., Elmsford, NY. Preferably, the glass substrate 2 is selected to have a higher thermal conductivity than the wavelength converting material 5 adhered thereto. Alternatively, undoped yttrium aluminum garnet (YAG), sapphire or diamond can be used as the substrate.
夹具3将玻璃基板2保持在合适的位置，可选地，导热粘合剂4形成夹具3和玻璃基板2之间的黏结料。用导热夹具将基板夹在合适的位置是冷却玻璃基板2及粘附到其的材料(这里所描述的材料)的优选方式。优选地，夹具3由诸如铜或铝的导热材料形成；然而，可以采用本领域技术人员所熟知的任何导热材料。优选地，导热粘合剂4是导热硅粘合剂，例如能够从Parker Hannifin公司(www.chomerics.com)的分公司Chomerics得到的Chomerics CHO-THERM 1641。可选地，或者另外，利用传统上在电子设备中采用的散热器可以实现热冷却，其中散热器例如连接到夹具3或直接连接到玻璃基板2的铝或铜散热器。The clamp 3 holds the glass substrate 2 in place, optionally a thermally conductive adhesive 4 forms a bond between the clamp 3 and the glass substrate 2 . Clamping the substrate in place with thermally conductive clamps is the preferred way of cooling the glass substrate 2 and the materials adhered thereto (the materials described here). Preferably, the clamp 3 is formed from a thermally conductive material such as copper or aluminium; however, any thermally conductive material known to those skilled in the art may be used. Preferably, the thermally conductive adhesive 4 is a thermally conductive silicon adhesive such as Chomerics CHO-THERM 1641 available from Chomerics, a division of Parker Hannifin Corporation (www.chomerics.com). Alternatively, or in addition, thermal cooling can be achieved using heat sinks conventionally employed in electronic devices, such as aluminum or copper heat sinks attached to the clamp 3 or directly to the glass substrate 2 .
现在参考图4和1，波长转换材料5是能够黏结到玻璃基板2的荧光体树脂混合物。现在参考波长转换材料5的荧光体成分，优选地，其是基于YAG的荧光体(掺杂铈的钇铝石榴石(Ce3+:YAG))，其将激光束从445nm转换为具有白色LED灯泡或手电筒的发散度和外观的白色光束。“白光”部分地由原始的445nm蓝光组成，但是加入了来自荧光体的发射的广谱的其他波长(光谱中绿色到红色的部分)。荧光体吸收部分445nm光并散射剩下的光。被吸收的部分通过荧光体的斯托克斯转换效应被转换为较长波长的光。荧光体还可以是黄色氮氧化合物荧光体。关于树脂，其是具有比玻璃基板2更低的导热性的树脂粘合剂，因此需要增加玻璃基板2以从荧光体吸收热并将热输送走。优选地，树脂粘合剂是光学透明的环氧树脂或硅树脂，例如可以从位于英国布里奇沃特(Bridgewater)的ACCSilicones有限公司得到的ACC Silicones QLE1102或ACC SiliconesQsi1222。Referring now to FIGS. 4 and 1 , the wavelength converting material 5 is a phosphor resin mixture capable of being bonded to the glass substrate 2 . Referring now to the phosphor composition of the wavelength conversion material 5, preferably, it is a YAG based phosphor (cerium doped yttrium aluminum garnet (Ce3+:YAG)), which converts the laser beam from 445nm to have a white LED bulb or The divergence and appearance of the flashlight's white beam. "White light" consists in part of the original 445nm blue light, but with the addition of a broad spectrum of other wavelengths emitted from the phosphor (green to red part of the spectrum). Phosphor absorbs some of the 445nm light and scatters the rest. The absorbed portion is converted to longer wavelength light by the Stokes conversion effect of the phosphor. The phosphor may also be a yellow oxynitride phosphor. As for the resin, it is a resin adhesive having lower thermal conductivity than the glass substrate 2, so the glass substrate 2 needs to be added to absorb heat from the phosphor and transport it away. Preferably, the resin binder is an optically clear epoxy or silicone, such as ACC Silicones QLE1102 or ACC Silicones Qsi1222 available from ACC Silicones Ltd, Bridgewater, UK.
再次参考图4，2轴(X和Y)透射衍射光栅6用于进一步降低波长转换材料5包括树脂的局部加热。通常可得到的1W445nm便携式激光器的近场输出由具有包括在2mm×0.75mm区域内的大部分功率的色条组成。以这种功率密度，包含荧光体的树脂很容易过热，引起变色或碳化(热点)。为了防止热点，可以借助于在照明光束击到玻璃基板2之前发送照明光束通过2轴(X和Y)衍射光栅或其他分散设备来增加荧光体的有效照明区。与没有2轴衍射光栅(如图6中)相对比，根据本发明实施方式的图7描述了激光源穿过2轴衍射光栅后的示例性的的打击(striking)图案。通过发射照明光束通过衍射光栅，照明激光功率在更大的荧光体区域上传播开，防止了“热点”的形成。在图7中，光栅将源光束分为5乘5阵列的输出光束。由于输入光束的椭圆形的条纹形状，输出光束在y轴上重叠。如果光栅旋转45度，光点将会在X轴和Y轴上重叠，然而，这对于产生均匀的输出并不是严格需要的，这是由于荧光体树脂混合物的漫反射特性。优选地，分散设备是凹透镜或双凹面透镜，透射衍射光栅或透射全息元件。Referring again to Figure 4, a 2-axis (X and Y) transmission diffraction grating 6 is used to further reduce localized heating of the wavelength converting material 5, including the resin. The near-field output of commonly available 1W 445nm portable lasers consists of a color stripe with most of the power contained within a 2mm x 0.75mm region. At this power density, the phosphor-containing resin can easily overheat, causing discoloration or carbonization (hot spots). To prevent hot spots, the effective illumination area of the phosphor can be increased by sending the illumination beam through a 2-axis (X and Y) diffraction grating or other dispersion device before it hits the glass substrate 2 . In contrast to without a 2-axis diffraction grating (as in FIG. 6 ), FIG. 7 depicts an exemplary striking pattern of a laser source passing through a 2-axis diffraction grating, according to an embodiment of the present invention. By sending the illuminating beam through a diffraction grating, the illuminating laser power is spread over a larger phosphor area, preventing the formation of "hot spots". In Figure 7, a grating splits the source beam into a 5 by 5 array of output beams. Due to the elliptical fringe shape of the input beams, the output beams overlap on the y-axis. If the grating is rotated by 45 degrees, the spots will overlap in the X and Y axes, however, this is not strictly necessary to produce a uniform output due to the diffuse reflective properties of the phosphor resin mixture. Preferably, the dispersion device is a concave or biconcave lens, a transmission diffraction grating or a transmission holographic element.
模块支持器7，也被称为转换器外壳，用于容纳组件1-6和8，并允许借助于如图1中所述的螺纹螺丝安装激光源，例如便携式激光器。应该理解可以借助于任何通常使用的装置来将激光源连接到转换器外壳上，这些装置包括夹子、有槽的配件或类似装置。通常地，该转换器设备将用于1W445nm便携式激光器，然而其他瓦特或波长的激光器也容易被替换以用于该转换器。The module holder 7, also known as the converter housing, is used to accommodate the components 1-6 and 8 and allows mounting of a laser source, such as a portable laser, by means of threaded screws as described in FIG. 1 . It should be understood that the laser source may be attached to the transducer housing by any commonly used means including clips, slotted fittings or the like. Typically this converter device will be used with a 1W 445nm portable laser, however other wattage or wavelength lasers can easily be substituted for this converter.
透明塑料或玻璃窗口8用于阻止灰尘和污垢接触部件1-6。进一步地，透明塑料或玻璃窗口8用于阻止用户和热表面直接的接触，并且还阻止用户接触或外部物体接触内部组件1-6，而这种接触可能导致部件1-6的损坏。Transparent plastic or glass windows 8 are used to keep dust and dirt out of the components 1-6. Further, the transparent plastic or glass window 8 serves to prevent direct user contact with the hot surface, and also prevents user contact or external objects from contacting the internal components 1-6, which could result in damage to the components 1-6.
在另一实施方式中，参考图5，由于来自波长转换材料的光输出基本上是朗伯光，因此聚焦以减小输出光束角会提供像手电筒那样更好的照明。这可以通过将波长转换材料放置在弯曲的反射器中或通过将光发射进入全内反射/折射光学元件中来实现，所述光学元件类似于那些用于准直大功率LED的光学元件。In another embodiment, referring to Figure 5, since the light output from the wavelength converting material is substantially Lambertian, focusing to reduce the output beam angle provides better illumination like a flashlight. This can be achieved by placing wavelength-converting materials in curved reflectors or by launching light into total internal reflection/refraction optics, similar to those used to collimate high-power LEDs.
现在特别参照图1和2描述本发明实施方式的操作。来自便携式激光源的准直光束(9)被透射的2轴衍射光栅(6)分散并被分为多个照明光束(10)。分散的光束在击到一片波长转换材料(5)之前穿过玻璃二向色反射镜(2)。波长转换材料将一些照明光转换为较长波长的光，其与来自照明光束的散射光结合生成不同颜色的输出(11)。由波长转换过程在波长转换材料中产生的热被夹具(3)和热粘合剂(4)从玻璃基板移除。来自波长转换材料的光输出基本上是朗伯光，直到其被反射器(1)聚焦为更窄的光束。外部的外壳(7)在外部有螺纹以允许连接到普通的便携式激光器。透明窗口(8)阻止灰尘和污垢污染反射器和波长转换材料。Operation of an embodiment of the present invention will now be described with particular reference to FIGS. 1 and 2 . A collimated beam (9) from a portable laser source is dispersed by a transmitted 2-axis diffraction grating (6) and split into multiple illumination beams (10). The dispersed beam passes through a glass dichroic mirror (2) before hitting a sheet of wavelength converting material (5). The wavelength conversion material converts some of the illumination light to longer wavelength light, which combines with scattered light from the illumination beam to generate a different colored output (11). Heat generated in the wavelength converting material by the wavelength converting process is removed from the glass substrate by the clamp (3) and thermal adhesive (4). The light output from the wavelength converting material is essentially Lambertian until it is focused into a narrower beam by the reflector (1). The outer housing (7) is externally threaded to allow connection to common portable lasers. The transparent window (8) prevents dust and dirt from contaminating the reflector and wavelength converting material.
可选地，将激光束聚焦到包括基板的荧光体上的其他装置也是可能的。位于远处的波长转换荧光体可以是被前部照明或者被后部照明。多数被转换的光从与用于照明的光相同一侧发射，因此前部照明的方式是最高效的。此外，从热量的角度来看，前部照明的方式将允许荧光体和树脂接合剂被沉淀在导热和反光的金属基板上，因此有助于冷却荧光体/树脂混合物和反射从荧光体的后侧面发射的向前的光。这样，可以将光束布置为聚焦到如图8所示的转换器中。例如，照明光束(或多个光束)射击通过荧光体并接着被设计用于相同用途的反射镜、反射镜阵列或衍射光学元件向后反射朝向所述荧光体。将光束发送通过荧光体会引起反射镜/多个反射镜的对准问题。这种配置使得输出与原始光束成一角度或从原始光束移开。Alternatively, other means of focusing the laser beam onto the phosphor comprising the substrate are also possible. The remotely located wavelength converting phosphor can be either front illuminated or back illuminated. Most of the converted light is emitted from the same side as the light used for illumination, so the front lighting approach is the most efficient. Also, from a thermal point of view, the way the front is illuminated will allow the phosphor and resin bond to be deposited on the thermally conductive and reflective metal substrate, thus helping to cool the phosphor/resin mix and reflection from the back of the phosphor A forward light emitted from the side. In this way, the light beam can be arranged to be focused into a converter as shown in FIG. 8 . For example, an illumination beam (or beams) is shot through the phosphor and then reflected back towards the phosphor by a mirror, mirror array or diffractive optical element designed for the same purpose. Sending the beam through the phosphor can cause alignment problems for the mirror/mirrors. This configuration is such that the output is at an angle or moved away from the original beam.
在又一实施方式中，反射器可以被用于将光反射到如图9所述的反射器上。因此，通过悬挂金属反射镜并借助于这里所述的以及例如连接到反射镜后表面的散热器将热量从其移除，来实现将从相同侧发射的光用作照明。仍然进一步地，如图3所示，用导热结构冷却荧光体安装的透明基板，来实现采用透明基板并利用从荧光体的两侧发射的光。例如，产生导热和安装功能并填充反射器的整个内径了薄片也是由基板优选地金刚石晶片实现的。In yet another embodiment, a reflector may be used to reflect light onto the reflector as described in FIG. 9 . Thus, the use of light emitted from the same side as illumination is achieved by suspending the metal mirror and removing heat from it by means of a heat sink as described herein and eg connected to the rear surface of the mirror. Still further, as shown in FIG. 3 , the transparent substrate on which the phosphor is mounted is cooled by a heat conduction structure, so as to realize the use of the transparent substrate and utilize the light emitted from both sides of the phosphor. For example, the thin slices that perform the thermal conduction and mounting functions and fill the entire inner diameter of the reflector are also performed by the substrate, preferably a diamond wafer.
应该知道本设备可以包括多个激光器和转换器，或者可以为了输入多个转换器而将激光束分为多个光束。It should be understood that the device may comprise multiple lasers and converters, or may split a laser beam into multiple beams for input to multiple converters.
