背景技术
正在持续不断地努力研发更加能量高效的系统。由于美国所产电力的大部分(一些估计为高达百分之二十五)被用于照明,正在持续不断地努力提供更加能量高效的照明。固态照明装置(例如,发光二极管)受到关注,因为使用固态照明装置能够比使用常规白炽或荧光灯泡更加高效地产生光。而且,固态照明装置的寿命可显著地长于常规白炽或荧光灯泡的寿命。
然而,常规灯泡通常使用120伏的AC电力来工作,通过爱迪生灯座(Edison fixture)来提供该AC电力,爱迪生灯座构造成接收设置在常规灯泡上的爱迪生螺纹接头(Edison screw fitting)。因此,现有建筑通常在围墙中设置有爱迪生灯座以接收常规灯泡,而固态照明装置可能需要DC电力。而且,如果没有提供适当的冷却,固态照明装置的性能和寿命可受负面影响,而用于常规灯泡的常规灯座(例如照明罐)所提供的空间可能无法容易地容纳通常为固态照明装置提供的冷却结构。
因此,本领域依然存在对于更加高效且可与现有AC照明灯座兼容的照明装置的需求。

具体实施方式
现在将参照附图更全面地描述本发明,附图中示出了各种实施例。然而,本发明可具体实施为许多不同形式并且不应当被理解为局限于本文所述的实施例。当然,所提供的这些实施例使得本公开将会是彻底和完整的,并且将向本领域技术人员全面地传达本发明的范围。在附图中,为了清楚,层和区域的尺寸和相对尺寸可能是夸张的。自始至终,相同的附图标记指代相同的元件。
本文所使用的术语仅仅为了描述具体实施例而不是意图限制本发明。如本文所使用的,单数形式“一”、“一个”、“该”意图也包括复数形式,除非上下文清楚地另有所指。还应当理解的是,当用在本说明书中时,术语“包括”和/或“包含”指定了所述特征、步骤、操作、元件和/或部件的存在,但不排除一个或多个其它特征、步骤、操作、元件、部件和/或其组合的存在或添加。作为对比,当用在本说明书中时,术语“由……组成”指定了所述特征、步骤、操作、元件和/或部件,并且排除了另外的特征、步骤、操作、元件和/或部件。
应当理解,当诸如层、区域、衬底或元件的元件被称为在另一元件“上”,其可以直接在该另一元件上或者二者之间也可存在中间元件。类似地,当层、区域、衬底或元件被称为“连接到”或“耦接到”另一元件,其可直接连接到该另一元件或者二者之间也可存在中间元件。此外,诸如“在……下面”或“在……上面”的相对性术语在本文中可用于描述如附图所示的一个层或区域相对于衬底或基底与另一层或区域的关系。应当理解,这些术语除了附图所示的取向之外还意图涵盖装置的不同取向。最后,术语“直接”意味着没有中间元件。如本文所使用的,术语“和/或”包括所关联的列出的项目中的一个或多个的任何和所有组合,并且可简写为“/”。
应当理解,尽管术语第一、第二等在本文中可用于描述各种元件、部件、区域、层和/或区段,但这些元件、部件、区域、层和/或区段不应当局限于这些术语。这些术语仅仅用于将一个元件、部件、区域、层或区段与另一区域、层或区段区分开。因此,在不偏离本发明的教导的情况下,下面所讨论的第一元件、部件、区域、层或区段可称为第二元件、部件、区域、层或区段。
在本文中,参照剖视图和/或其它图来描述本发明的实施例,所述剖视图和/或其它图是本发明的理想实施例的示意图。这样,应当预期到例如由于制造技术和/或公差而造成从所示形状发生变化。因此,本发明的实施例不应被理解为局限于本文所示区域的特定形状,而是也包括例如由于制造而造成的形状偏差。例如,被示出或描述为矩形的区域通常由于正常制造公差而将会具有圆形的或弯曲的特征。因此,图中所示的区域本质上是示意性的并且它们的形状并不意图表示装置的区域的确切形状并且也不意图限制本发明的范围,除非本文中另有所指。而且,本文所描述的所有数量均是近似的并且不应被视为是精确的,除非这样指明。
除非本文另有限定,本文使用的所有术语(包括技术术语和科学术语)具有与本发明所属技术领域的普通技术人员所通常理解的相同的含义。还应当理解,术语(诸如常用词典中定义的那些术语)应当被解释为具有与它们在本说明书和相关技术的上下文中的含义一致的含义,并且不应当以理想的或过于正式的方式对其进行解释,除非本文明示地如此限定。
如本文所使用的,当照射到层或区域的辐射的至少50%透过该层或区域时,该层或区域被认为是“透明的”。而且,对于任何(一种或多种)波长转换材料均同义地使用术语“磷光体”。
本文描述的一些实施例可使用发光装置,例如碳化硅(SiC)基安装衬底上的氮化镓(GaN)基固态发光二极管。然而,本领域技术人员将会理解的是,本发明的其它实施例可基于安装衬底和外延层的多种不同组合。例如,所述组合可包括GaP安装衬底上的AlGaInP固态发光二极管;GaAs安装衬底上的InGaAs固态发光二极管;GaAs安装衬底上的AlGaAs固态发光二极管;SiC或蓝宝石(Al2O3)安装衬底上的SiC固态发光二极管和/或氮化镓、碳化硅、氮化铝、蓝宝石、氧化锌和/或其它安装衬底上的三族氮化物基固态发光二极管。而且,在其它实施例中,在已完成的产品中可以没有安装衬底。在一些实施例中,固态发光装置可以是如cree.com所一般性描述的由北卡罗莱纳州Durham的Cree
Inc.制造和销售的氮化镓基发光二极管装置。
图1A-1H、2、3和4示出了根据本发明的一些实施例的照明装置101及其元件。具体地,图1A、1B、1C和1D分别是照明装置101的前视图、右视图、左视图和后视图,并且图1E和1F分别是照明装置101的顶视图和底视图。图1G和1H是照明装置101的透视图,图2A和2B分别是导热壳体107的前视图和顶视图,与图1A-1H具有相同的比例,并且图3是照明装置101的前视图,连同示出了常规照明装置的最大尺寸(例如PAR30L和/或BR30灯泡的最大尺寸)。图4是照明装置101沿图1E的剖面线I-I’剖切的剖视图。此外,在图1A、1F和2中,照明装置101的尺寸以毫米(mm)为单位示出。
如图1A-1H、2、3和4所示,照明装置101可包括爱迪生螺纹接头103、基座壳体105(例如塑料基座壳体)、导热壳体107、透镜109和紧固件孔111。另外,驱动器电路119(在基座壳体105中)可电耦接在发光装置115和爱迪生螺纹接头103之间。如图4所示,多个发光装置115可设置在衬底121(例如金属芯印刷电路板)上,并且发光装置115可设置在混合室123附近/之中,混合室123由反射侧壁117和透镜109限定。例如,可使用塑料侧壁117a及其上的反射涂层117b来提供反射侧壁117,或者可使用天然反射物质来提供反射侧壁117。
例如可使用MCPET(微泡沫聚对苯二甲酸乙二酯)来提供反射涂层117b,例如在Furukawa Electric Co., Ltd.于2008年4月8日更新的、标题为“New Material for Illuminated Panels Microcellular
Reflective Sheet MCPET”的数据单以及2007年5月23日的LED Magazine的标题为“Furukawa
America Debuts MCPET Reflective Sheets to Improve Clarity, Efficiency of
Lighting Fixtures”文章中描述了MCPET,二者的公开内容在此通过引用全文并入本文中,如同完整地在本文中展示一样。另外或替代地,可使用漫反射材料(DLR)来提供反射涂层117b,例如在2008年5月的DuPont出版物K-20044中的标题为“DuPont ™ Diffuse Light Reflector”的数据单中以及在diffuselightreflector.dupont.com上描述了漫反射材料,二者的公开内容在此通过引用全文并入本文中,如同完整地在本文中展示一样。
因此,照明装置101可构造成旋入常规的120伏AC灯泡插座中,并且驱动器电路119可构造成将120伏AC输入转换为适于驱动发光装置115的(一个或多个)DC输出。发光装置115可以是半导体固态发光装置,例如发光二极管和/或激光二极管,其各自发生特定波长的光。因此,不同颜色的发光装置和/或磷光体可一起用于产生基本白色的光。例如在授予Anthony
Paul Van De Ven等人的、名称为“Lighting Device
And Method”美国专利No. 7,213,940中讨论了将不同颜色的发光二极管及磷光体一起用在同一发光装置中以产生基本白色的光,该文献的公开内容在此通过引用全文并入本文中。磷光体可例如设置在直接施加在发光装置115上的涂层中,设置在反射涂层117b中/上,和/或设置在透镜109中/上。从而,来自发光装置115的光进入混合室123,从反射涂层117b反射,并且穿过透镜109离开以提供照明。反射涂层117b例如可基本上仅仅提供反射,提供反射和漫射,提供反射和磷光性,或者提供反射、漫射和磷光性。类似地,透镜109可基本上仅仅提供透射,提供透射和漫射,提供透射和磷光性,或者提供透射、漫射和磷光性。通过在涂层117b和/或透镜109处提供漫射,可提供相对均匀的白光照明,从而单独的发光装置不表现为分立的源。透镜109可以提供或不提供光的聚焦。
发光装置115的性能和/或有用寿命可能由于升高的温度而降低,并且发光装置115可在操作期间产生显著的热量。因此,衬底121可构造成将热量从发光装置115传导到导热壳体107,导热壳体107的基座107b可在衬底121后面延伸。因此,导热壳体107可包括基座107b和侧壁107a,基座107b热耦接到发光装置115,侧壁107a暴露于外侧环境。因此,在不需要翅片的情况下,导热壳体107可将发光装置115产生的热量传递/辐射/传导到照明装置101外侧的环境中。因此,导热壳体107的侧壁107a的外表面可以是基本平的和/或关于装置的中心轴线CA轴向对称的。另外,可在导热壳体107的基座107b上设置散热器125(例如铝板),从而导热壳体107的基座107b被夹在散热器125和衬底121中间。从而,散热器125可进一步降低对于从发光装置115传走的热量的热阻。另外,可在衬底121和导热壳体107的基座107b之间和/或基座107b和散热器125之间设置石墨片,以降低它们之间的接触热阻。
如图4进一步示出的,反射侧壁117可延伸离开发光装置115,并且导热壳体107的侧壁107a可与反射侧壁117间隔开以限定反射侧壁117和导热壳体107的侧壁107a之间的腔131。从而,可使用相对便宜且重量轻的模制塑料侧壁117a及其上的反射涂层117b来提供反射侧壁117,同时可使用相对重量轻且导热的金属(例如铝)来提供导热壳体107(包括侧壁107a和基座107b)。虽然在图1A-H、2A-B或3中未示出,导热壳体107的侧壁107a可包括穿过其中的孔以提供腔131和外侧环境之间的流体连通(例如,通风),由此进一步增强从导热壳体107去除热量。从而,穿过此类孔的空气对流可增强从导热壳体107的内表面去除热量,以对从导热壳体107的外表面去除热量进行补充。
通过提供从导热壳体107的基本平滑的侧壁107b的充分热传递/热辐射/热传导,照明装置101可构造成用在常规灯座中,例如适合于PAL30L和/或BR30型灯泡的灯座。例如,图1A和1F示出了根据本发明的一些实施例的照明装置101的尺寸,并且图3示出了照明装置101的外形处于常规灯泡所允许的最大轮廓之内。所有的尺寸以毫米(mm)为单位,并且相对于照明装置101的尺寸,图3的所有尺寸是针对最大常规轮廓的。导热壳体107的最大宽度可在约90 mm到约110 mm的范围内,并且如图1A和1F所示,导热壳体的最大宽度可约为100 mm。而且,导热壳体107的外表面可以以相对于中心轴线CA大于约145度的角度渐缩,并且如图1A所示,导热壳体107的外表面可以以约150度的角度渐缩。而且,基座壳体105的外表面可沿着与导热壳体105的外表面的渐缩角相同的角度继续渐缩到与爱迪生螺纹接头103的宽度大约相同或略大的宽度(例如约33 mm),而爱迪生螺纹接头103可具有约27 mm的宽度。
从而,对于基座壳体105和反射侧壁117可使用相对便宜且重量轻的塑料,而对于导热壳体107可使用导热材料(例如铝)来组装图1A-H、2A-B、3和4的照明装置101。穿过基座壳体105、导热壳体和反射侧壁117的对准的紧固件孔111可提供高效的组装,例如使用螺钉、卡口配件等。从而,铝制的连续导热壳体107(包括侧壁107a和基座107b)可提供高效的热传递/热辐射/热传导,而不显著增加成本和/或重量。而且,通过在没有翅片的情况下通过导热壳体107提供热传递/热辐射/热传导,照明装置101可适于作为常规灯座中的常规灯泡的替代品,而不显著降低发光装置115的性能和/或寿命。
如图1A-H、2A-B、3和4所示,导热壳体107的剖面可以关于照明装置101的中心轴线CA基本对称,外表面的最接近发光装置107的第一宽度小于该外表面的更远离发光装置107的第二宽度。更具体地,导热壳体的侧壁107a可限定基本截头圆锥形形状,具有从较宽部分到较窄部分的基本直线的斜坡。根据本发明的其它实施例,侧壁107a的剖面轮廓可具有凹的斜坡(就像铃铛的下部)或者凸的斜坡(就像铃铛的上部)。
此外,透镜保持器141可提供透镜109和导热壳体107之间的机械耦接,并且透镜109可由透明/半透明材料形成,例如玻璃或塑料。如上所述,透镜109可在光透射之外还提供漫射和/或磷光性。可通过使透镜109的表面形成精细图案(例如隆起、脊等),通过在透镜109的表面上提供光漫射膜,通过使光漫射颗粒分散在透镜109的体积内等等方法来提供光漫射。可通过在透镜109的体积内和/或透镜109的表面上的膜中提供磷光颗粒(例如磷光体)来提供磷光性。
图5和6根据本发明的其他实施例的照明装置101’的透视图和剖视图。除了导热壳体107’包括穿过其侧壁107a’的开口151以及反射侧壁117和导热壳体107’之间的腔中包括另外的散热元件155之外,照明装置101’与照明装置101相同。照明装置101’的其它元件与上面关于照明装置101所讨论的那些元件相同,并且对于相同的元件使用相同的附图标记。为了简明起见,可省略相对于照明装置101不变的元件的进一步讨论。
从而,开口151可提供导热壳体107’内侧的腔131和导热壳体107’外侧的空间之间的流体连通(例如通风),以进一步促进冷却。更具体地,通过允许穿过导热壳体107’的流体连通(例如空气流),可促进导热壳体107’的侧壁107a’的内表面和外表面二者的冷却。穿过导热壳体107’的流体连通还可促进通过腔131中的散热元件155的冷却。
如图6所示,散热元件155可设置在反射侧壁117和导热壳体107’之间的腔131中。而且,散热元件155的基座155b可与发光装置115热耦接,并且散热元件155的侧壁155a可与反射侧壁117和导热壳体107’二者间隔块。更具体地,散热元件155可由相对轻的导热金属(例如铝)形成。从而,穿过导热壳体107’的侧壁107a’的开口151可促进热量从导热壳体107’和散热元件155耗散。因此,散热元件155可有效地增加来自发光装置115的热量可从其耗散的表面积。
如图6所示,散热元件155(包括侧壁155a和基座155b)可与导热壳体107’分开地形成,并且然后通过对准(基座壳体105、导热壳体107’、散热元件155和反射侧壁117的)紧固件孔111并施用紧固件来组装。从而,散热元件155可具有类似于图2A和2B中对于导热壳体107所示形状的形状,主要区别在于散热元件的尺寸按比例充分地减小以允许散热元件155配合在腔131中,如图6所示。换句话说,基座155b的一些部分(包括穿过其中的紧固件孔111)可设置在衬底121(例如金属芯印刷电路板)和导热壳体107’的基座107b’之间,并且散热元件155的侧壁155a可延伸到腔131中,腔131经由穿过导热壳体107’的侧壁107a’的开口151来通风。
根据本发明的其它实施例,导热壳体107’和散热元件155可设置为共享单个基座的单个金属(例如铝)件。更具体地,导热壳体107’的基座107b’可设置在衬底121和铝板125之间,并且散热元件155的侧壁155a可直接从导热壳体107’的基座107b’延伸。从而,可通过降低分开的基座155b和107b’之间的热界面来降低发光装置115和导热壳体107’的侧壁107a’之间的热阻。
导热壳体107和散热元件155的剖面可关于照明装置101’的中心轴线CA基本对称,它们的外表面的最接近发光装置115的第一宽度小于该外表面的更远离发光装置115的第二宽度。更具体地,散热元件155的侧壁155a和导热壳体107’的侧壁107a’二者均可具有基本截头圆锥形形状,并且散热元件155的侧壁155a可具有比导热壳体的侧壁107a’更加竖直的斜坡。图7A和7B分别是根据本发明一些实施例的具有基本截头圆锥形形状的散热元件155的前视图和顶视图。根据本发明的其它实施例,导热壳体107’的侧壁107a’和/或散热元件155的侧壁155a的剖面轮廓可具有凹的斜坡(就像铃铛的下部)或者凸的斜坡(就像铃铛的上部)。
如图6所示,散热元件155的侧壁155a的长度可小于导热壳体107的侧壁107a’的长度,以允许腔131的位于散热元件155和反射侧壁117之间的部分和腔131的位于散热元件155和导热壳体107’之间的部分之间的流体连通(例如通风)。根据本发明的其它实施例,可使用穿过散热元件的侧壁155a的开口和/或散热元件的侧壁155a中的间隙来提供腔131的位于散热元件155和反射侧壁117之间的部分和腔131的位于散热元件155和导热壳体107’之间的部分之间的流体连通。根据本发明的又一些其它实施例,散热元件155的侧壁155a可设置为间隔开的其间具有间隙的瓣片,以允许瓣片下面、周围和/或之间的流体连通。图8A和8B分别是根据本发明一些其他实施例的散热元件155’的前视图和顶视图。基座155b’可相对于图7A和7B的基座155b不变,然而侧壁155a’可包括多个间隔开的瓣片,而不是提供连续的截头圆锥形形状。
本发明已经连同上面的描述和附图公开了许多不同的实施例。应当理解,用文字来描述和说明这些实施例的每种组合和子组合将会是过分重复的且造成混乱。因此,本说明书(包括附图)应当被理解为构成了本文所述实施例的所有组合和子组合及其制造和使用的方式和方法的完整书面描述,并且应当针对此类组合或子组合对权利要求形成支持。
