Description
本申请是名称为“LED灯具”、国际申请日为2009年4月3日、国际申请号为PCT/US2009/002100、国家申请号为200980118971.3的发明专利申请的分案申请。
技术领域
本发明涉及一种灯具,并且更具体地涉及街道和道路灯具及其类似物,包括用于大面积照明的灯具。更具体地,本发明涉及使用LED作为光源的灯具。
背景技术
近年来,用于各种普通照明目的的发光二极管(LEDs)的使用越来越多,并且随着对LEDs和通常称作“LED模块”的LED阵列支撑设备的改进该趋势已经越来越加速。实际上,过去由使用高强度放电(HID)灯泡和其它光源的灯具提供的照明应用现在开始日益由LED模块提供。在许多其它的应用中,这种照明应用包括道路照明、停车场照明和工厂照明。在LED模块研发领域、以及同样在将LED模块用于各种应用中灯具的领域持续进行创造性的工作。本发明涉及将LED模块用于各种应用中灯具的领域。
使用LED模块作为道路和类似应用的光源的高亮度灯具存在特别挑战性的问题。当高亮度、高可靠性和高耐用性对于产品成功必不可少时,由于高复杂性导致的高成本变成特别困难的问题。将电子的LED驱动器保持在水/空气密封位置也可能是有问题的,特别是当在道路照明等时候,灯具通常暴露于自然环境并且使用许多的LED模块。
另一个与成本相关的挑战是获得较高水平适应性的问题,以便满足较宽的不同亮度需求。也就是说,提供一种能够适合提供认为适合应用的明显更高或更小的亮度的灯具是一个难题。对于LED灯具而言灯具的适应性是一个重要的目标。
处理散热的需求对于高亮度LED灯具也是另一个问题。散热是困难的,部分是因为高亮度LED灯具典型地具有大量的LED和若干个LED模块。用于模块安装和散热的复杂结构有时被认为是必须的,并且所有这些增加了复杂性和成本。
简而言之,在灯具工业中具有对改进的道路灯具以及类似使用LED的道路灯具的大量需求。对于灯具需要能够适应于较大范围的照明位置,并且满足与散热和对电子LED驱动组件的适当保护相关的问题。最后,需要一种改进的基于LED模块的灯,该灯简单并易于制造且制造便宜。
发明目的
本发明的一个目的在于提供一种改进的LED灯具,其克服了现有技术的一些问题和缺点,包括上面涉及到的那些。
本发明的另一目的在于提供一种改进的LED灯具,其减少将LED灯具用于需要较宽不同亮度水平应用的研发和制造成本。
本发明的另一目的在于提供一种改进的高亮度LED灯具,其具有优良的可靠性和耐用性,纵使在恶劣的室外环境中使用。
本发明的又一目的在于提供一种改进的LED灯具,其获得优良的散热还包括最小的结构复杂性。
这些和其它目的怎样实现从下面的描述和附图将变得显而易见。
发明内容
本发明是在LED灯具方面的改进,特别用于街道和道路照明等等。
本发明的LED灯具包括一壳体,其本身包括至少一个末端部分和关于该末端部分固定的整体挤出件。整体挤出件,其优选由铝或类似的金属或金属合金制成,包括一底座,其具有LED邻接面、相对面和散热部分,所述散热部分具有从该相对面延伸的散热面。本发明的灯具进一步包括相对于壳体以非水/空气密封状态安装到LED邻接面的LED装置。
在本发明灯具的一高度优选的实施方式中,壳体在至少一个末端部分和整体挤出件之间形成至少一个通风孔,以使得冷空气进入到散热面并通过来自该散热面的热空气的向上流动而沿着散热面流动。
在一些优选的实施方式中,所述至少一个末端部分包括第一末端部分,该第一末端部分优选形成一水/空气密封腔室,该水/空气密封腔室封闭至少一个电子LED驱动器和/或LED所需的其它电子器件。本发明的高度优选的实施方式包括一第二末端部分。整体挤出件包括第一端部和第二端部,该第一端部和第二端部带有分别相对于挤出件的第一端部和第二端部固定的第一末端部分和第二末端部分。这些实施方式优选包括在每个末端部分和整体挤出件之间的通风孔。在这些实施方式中,第二末端部分形成一端盖。
在挤出件的第一端部处的第一末端部分具有一下表面和一挤出件邻接端面。在本发明的LED灯具的高度优选的实施方式中,挤出件邻接端面和下表面形成一第一凹部,该第一凹部延伸远离挤出件的第一端部并限定第一通风孔。沿着第一凹部的端面优选地递减以致第一通风孔向上变窄,由此引导并加速沿着散热面的气流。
在本发明这些高度优选的实施方式中,在挤出件第二端部处的端盖具有一内表面和一下边缘部分。另外高度优选地,端盖的内表面和下边缘部分形成一第二凹部,该第二凹部延伸远离挤出件的第二端部并限定第二通风孔。沿着第二凹部的内表面优选地递减以致第二通风孔向上变窄,由此引导并加速沿着散热面的气流。
在本发明的优选实施方式中,LED装置包括至少一个LED阵列模块。LED装置最优选地包括多个LED阵列模块。LED阵列模块优选为基本矩形的细长模块。LED阵列模块的实施例在共同在理中的美国专利申请No.11/774,422中公开,其内容在此结合作为参考。
在优选的实施方式中,每一个LED阵列模块具有相同的模块宽度,并且挤出件的底座的LED邻接面优选具有一宽度,该宽度近似为用相同的模块宽度乘以可按并排关系安装于所述LES邻接面上的LED阵列模块的最大数量。例如,如果LED邻接面上这种并排模块的最大数量为3个,LED邻接面的宽度约为模块宽度的3倍。
LED阵列模块进一步具有一预定的模块长度,该模块长度优选与模块上的LED的数量相关联。换句话说,如果模块在其上具有20个LED,其将具有预定的模块长度,而如果在其上具有10个LED,其将具有更短的预定的模块长度。优选LED邻接面具有一长度,该长度优选近似为选自预定的模块长度和LED阵列模块对的模块长度的总和中之一的尺寸。在一些高度优选的实施方式中,多个模块的至少一个的模块长度不同于多个模块的至少另一个的模块长度。LED邻接面优选选择尺寸近似对应于LED装置的长度。
本发明的灯具及其整体挤出件可以容易地适应于多种道路以满足较大范围的亮度需求。
在某些优选的实施方式中,多个LED阵列模块包括成互相首尾相连关系的LED阵列模块。这些模块包括靠近第一末端部分的模块和远离第一末端部分的模块。第一末端部分具有水/空气密封的电线入口,该电线入口接收来自近侧模块的电线。
在某些高度优选的实施方式中,挤出件包括水/空气密封的电线管道,该电线管道接收来自远侧LED阵列模块的电线,由此来自远侧模块的电线穿过该电线管道到达第一末端部分的水/空气密封腔室。该电线管道优选沿着散热部分延伸。散热部分优选包括沿着整体挤出件的长度的平行翅片。封闭的电线管道优选沿着翅片形成。
在高度优选的实施方式中,其中LED装置包括多个LED阵列模块,高度优选地整体挤出件的底座具有穿过所述底座的至少一个通风孔,以使得冷空气进入到散热面并通过来自该散热面的热空气的向上流动而沿着散热面流动。
通风孔优选包括穿过底座的至少大部分宽度的至少一个细长孔。优选地导向元件沿着细长孔固定到底座。导向元件具有至少一个倾斜的导向面,该导向面定向以便沿着散热面引导并加速气流。在一些优选实施方式中,导向元件包括一对相向面对的倾斜的导向面,所述导向面定向以便沿着散热面在相反方向中——也就是沿着不同模块上方的散热面——引导和加速气流。
在一些这种实施方式中,多个LED阵列模块优选包括互相呈纵向关系的LED阵列模块。通风孔包括至少一个远离(也就是远离)挤出件的第一端部和第二端部的孔-一个在大约中间位置的孔。
在一些这种实施方式中,多个LED阵列模块进一步包括至少一个(并且优选两个或更多个)靠近挤出件的第一端部的近侧LED阵列模块,和至少一个(并且优选两个或更多个)远离挤出件的第一端部的远侧LED阵列模块,远侧阵列模块与近侧LED阵列模块间隔开。远离挤出件的第一端部和第二端部的通风孔优选位于近侧LED阵列模块和远侧LED阵列模块之间的间隔处。
在刚刚描述的高度优选的实施方式中,LED邻接面具有一长度,该长度近似为(a)首尾相连的LED阵列模块对的模块长度的总和加上(b)在近侧LED阵列模块和远侧LED阵列模块之间的间隔的长度。最优选地,在这些实施方式中,LED邻接面进一步具有一宽度,该宽度近似为用相同的模块宽度乘以可按并排关系安装于所述LED邻接面上的LED阵列模块的最大数量。

具体实施方式
图1-36图示了本发明的LED灯具100A-100E的优选实施方式。在所有实施方式的附图中,相同或相似的部件给予相同的数字,并且探照灯通常由数字100指代,而没有在附图中使用的文字A或E,并且为了方便采用单数。
探照灯100包括壳体10,该壳体具有第一末端部分11和第二末端部分12,以及整体挤出件20,该整体挤出件具有第一端部201和第二端部202,第一末端部分11和第二末端部分12分别相对于第一端部201和第二端部202固定。整体挤出件20包括在第一端部201和第二端部202之间延伸的基本平面的底座22。底座22具有LED邻接面220和相对表面221。整体挤出件20还具有散热部分24,该散热部分具有从相对表面221延伸的散热面241。灯具100还包括相对于壳体10以非水/空气密封的状态安装到LED邻接面220的LED装置30。(参见图1,3,7,12-31)在这些实施方式中,第二末端部分12形成端盖120。
如至少在图7、12、14、27和30中最佳看到的,壳体10在每个端部11和12与整体挤出件20之间形成通风孔14,以使得冷空气3进入到散热面241并通过来自该散热面的热空气5的向上流动而沿着散热面流动。图8-10图示了空气穿过挤出件20的散热部分24的流动。热空气5的向上流动吸引冷空气3进入散热部分24中并沿着散热面241流动,而不需要借助于例如风扇或类似的机械设备。
如在图11中看到的,第一末端部分11形成一水/空气密封的腔室110,其封闭电子LED驱动器16和/或LED灯具所需的其它电子组件和电组件。第一末端部分11具有上部11A和下部11B,所述上部和下部通过铰链11C被铰接在一起。这个铰接装置通过下部11B的向下摆动而促进第一末端部分11容易打开。LED驱动器16安装在下部11B上以易于维护。
在挤出件20的第一端部201处的第一末端部分11具有一下表面111和挤出件邻接端面(extrusion-adjacent end surface)112。如在图7、27和30中最佳看到的,挤出件邻接端面112和下表面111形成一第一凹部(recess)114,该第一凹部延伸远离挤出件20的第一端部201并限定第一通风孔141。沿着第一凹部114的端面112递减以致第一通风孔141向上变窄,由此引导并加速沿着散热面241的气流。
在挤出件20的第二端部202处的端盖120具有一内表面121和一下边缘部分122。端盖120的内表面121和下边缘部分122形成一第二凹部124,该第二凹部延伸远离挤出件20的第二端部202并限定第二通风孔142。沿着第二凹部142的内表面121递减以致第二通风孔142向上变窄,由此引导并加速沿着散热面241的气流。
如在图1、3、7和11-31中最佳看到的,LED装置30被固定在水/空气密封腔室110的外侧并且没有灯罩。LED装置30包括多个LED阵列模块31或32。如在这些附图中还看出的,LED阵列模块31和32为基本矩形的细长模块。
LED阵列模块31和32每一个都具有相同的模块宽度310(参见附图12-31)。LED邻接面220A具有宽度222,该宽度近似为用相同的模块宽度310乘以可以按并排关系安装于所述LED邻接面上的LED阵列模块的最大数量。图13、15和16显示了在如图12和14中所示相同宽度222的LED邻接面220上LED阵列模块31的替换排列。
LED阵列模块还具有与模块31或32上的LED18的数量相关的预定模块长度。
图1和12最佳示出了具有模块31的LED灯具100A,所述每个模块31在其上具有10个LED18,该10个LED18确定模块长度311。灯具100A具有长度224A的LED邻接面220A,该长度近似为预定模块长度311的尺寸。
图3和14最佳示出了具有模块32的LED灯具100B,所述每个模块32在其上具有20个LED18,该20个LED18确定模块长度312。灯具100B具有长度224B的LED邻接面220B,该长度近似为预定模块长度312的尺寸。
图13和15图示了根据照明要求,LED灯具100怎样允许对安装在LED邻接面220上的模块31或32的数量进行改变。图16图示了在LED邻接面220B上不同长度的模块31和32的组合。
图17-20示出了具有模块32的LED灯具100C,所述每个模块32在其上具有20个LED18,该20个LED18确定模块长度312。灯具100C具有长度224C的LED邻接面220C,该长度近似为每个LED阵列模块32的模块长度312的两倍。图17-20示出了在相同宽度222的LED邻接面220C上替换的LED阵列模块32的排列。图21、22和22A示出了在LED邻接面220C上不同长度的模块31和32的组合。这种排列通过减少LED模块32的数量或者使用带有更少LED的模块31能够提供降低的照明亮度。
图23-26示出了LED灯具100D,其具有支撑多个不同模块长度的模块的LED邻接面220D-这些模块包括模块长度311的模块31(10个LED18)和模块长度312的模块32(20个LED18)。灯具100D具有长度224D的LED邻接面220D,其长度近似为一对LED阵列模块31和32以互相首尾相连关系的模块长度311和312之和。图23-26示出了在LED邻接面220D上LED阵列模块31和32的替换排列。
图17-26图示了具有多个以互相首尾相连关系的LED阵列模块31和32的灯具100C和100D。在这种排列中,这些模块这样定位,模块33靠近第一末端部分11,而模块34远离第一末端部分11。可以在图7、27和30中看到,模块31和32包括电线管道13,该电线管道分别连接第一末端部分11和第二末端部分12的水/空气密封电线入口113和123。
挤出件20包括用于接收来自远侧LED阵列模块34的电线19的水/空气密封电线管道26。电线管道26分别通过第一末端部分11和第二末端部分12的电线入口115和125连接至壳体10。来自远侧模块34的电线19通过连接至水/空气密封电线入口115的电线管道26到达第一末端部分11的水/空气密封腔室110。电线管道26沿着并穿过散热部分24延伸,并且与底座22间隔开。散热部分24包括沿着整体挤出件20长度的平行翅片242。图5和6图示了由翅片242形成并沿该翅片242的电线管道26。翅片242是一定位在挤出件20纵向轴线处的中间翅片。然而,电线管道26可以沿着任意其它的翅片形成。这种选择依赖于灯具结构并且决不局限于示出的实施方式。电线管道26可以任意距离离开底座22而沿着翅片242定位,这为电线19提供了安全的温度。因此,应该认识到电线管道26可以离开底座22最大的距离定位在翅片242的顶端。作为替换,如果温度特征允许,电线管道26可被设置靠近翅片242的中央并且更靠近底座22。
电线入口115、125和电线管道26提供在水/空气密封腔室和非水/空气密封环境之间的较小面积。该较小面积由在那附近的密封衬垫17隔离。在本发明的LED灯具100中,整体挤出件20相对于末端部分11和12的安装在密封衬垫17上提供足够的压力,以致不再需要额外的封条、硅等等。
图28-32示出了LED灯具100E,其中整体挤出件20E具有一个穿过其的通风孔28,以使得冷空气3进入到散热面241并通过来自散热面241的热空气5的向上流动而沿着散热面241流动。如图28、29、31和32中所示,通风孔28为穿过底座22的大部分宽度的细长(elongate)孔。图28-31进一步示出了沿着细长孔28固定到底座22的导向元件15。导向元件15具有一对相向面对的倾斜的导向面150,该导向面定向以便沿着散热面241在相反方向中引导并加速气流。
在LED灯具100E中,如图28-32所示,多个LED阵列模块31互相呈纵向关系。通风孔28远离挤出件20的第一端部201和第二端部202。
在LED灯具100E中,远侧LED阵列模块34与近侧的LED阵列模块33间隔开。通风孔28远离挤出件20的第一端部201和第二端部202,并且位于近侧的LED阵列模块33和远侧LED阵列模块34之间间隔29处。
灯具100E的LED邻接面220E具有长度224E。如图28中最佳看出的,长度224E近似为将(a)首尾相连的LED阵列模块31对的模块长度311的总和与(b)在近侧LED阵列模块33和远侧LED阵列模块34之间的间隔29的长度两者组合后的尺寸。如图28中进一步示出的,LED邻接面220E具有宽度222,该宽度近似为以并排关系安装于其上的3个LED阵列模块31的模块宽度310的倍数。
图33和34最佳图示了第一末端部分11,该第一末端部分11配置用于配合整体挤出件20及其电线管道26的排列。
图35和36图示了第二末端部分12,该第二末端部分12配置用于配合整体挤出件20及其电线管道26的排列,并且显示了电线入口123和125,电线19穿过该电线入口进入第二末端部分12,并且引导到电线管道26。
尽管已经结合具体实施方式示出和描述了本发明的原则,应该理解这些实施方式仅作为实施例并且不是限制性的。
