Description

一种发光装置 技术领域
本发明主要涉及固态光源发光领域，尤其涉及一种发光装置。
背景技术
现在主流的舞台娱乐灯光设备是电脑灯，主要有三大类，分别是光束灯、图案灯、染色灯。随后开始出现了多功能电脑灯，比如光束、图案和染色三合一电脑灯。这些灯具原本都采用卤素灯或者气体放电灯作为光源(包括普通气体放电灯和超高压汞灯)，卤素灯的发光效率非常低而且工作寿命非常短，已经逐渐被其他光源所取代，但卤素灯的显色性非常好，现在仍然被使用在一些对显色指数要求较高的灯具内。超高压汞灯是一种特殊的气体放电灯，具有极小的光学扩展量，但在其发光面积内的亮度的均匀性较差。由于光束灯需要使用光学扩展量较小的光源，所以超高压汞灯大多被使用在光束灯中，也有一些多功能电脑灯(比如光束、图案二合一电脑灯或者光束、图案、染色三合一电脑灯)使用超高压汞灯，但其图案和染色的效果欠佳，同时超高压汞灯对其工作温度的要求非常高，因此灯具厂家需要设计相对比较复杂的散热设计，且作为气体放电灯的一种，超高压汞灯的工作寿命也较短。普通的气体放电灯的光学扩展量比超高压汞灯大，但其可以做到较大的功率，而且其亮度的均匀性要优于超高压汞灯。所以大多用于专业的图案灯和染色灯内，同时也用于一些多功能电脑灯(比如三合一电脑灯)内。
近年来，随着LED光源技术的日益成熟，越来越多的灯具采用LED作为光源。LED光源作为绿色无污染的干净节能光源，已经被大量使用在舞台娱乐灯光领域。它有超长的工作寿命，高效的发光效率和优异的亮度均匀性，但是由于LED的发光面积大而且光成散射状发射，所以一般来说由LED组成的发光系统，其光学扩展量和发光面积都非常大。大功率的LED系统往往需要大量的LED，其光学扩展量和发光面积也会随之大大增加，目前由LED组成的发光系统还无法满足光束灯对于小光学扩展量的要求，绝大多数的LED光源或系统只能应用于图案灯和染色灯，只有极少部分的低功率、低亮度的光束灯使用LED作为光源，但其亮度和效率都无法满足大多数的应用需求，因此目前为止光束灯的主流光源仍是超高压汞灯。

本发明的较佳实施方式
为了使发明实现的技术手段、创造特征、达成目的和功效易于明白了解，下结合具体图示，进一步阐述本发明。

第一实施例
本发明的第一实施例是提供一种发光装置，通过结合发光晶体与固态光源所发出的光谱配合各类光学元器件构成一个白光或彩光系统，具有光学扩展量小、均匀性好、发光效率高、寿命长、散热设计简单等优点，克服了一般LED光学扩展量大的缺点，且随着固态光源数量的增加其光学扩展量不会大幅度增加，从而实现大功率小光学扩展量的效果，可适用于需要高光照强度或小光学扩展量的系统中，比如娱乐照明系统、投影系统、汽车照明系统、医疗照明系统、探照照明系统、野外作业照明系统、航海照明系统、便携式照明系统等。
图1为本发明一种发光装置第一实施例的一剖面结构示意图。如图1所示，该发光装置包括发光晶体元件201、光学透明体元件202、第一固态光源103、第二固态光源104以及光线提取器105。
发光晶体元件201具有晶体元件前端面、晶体元件后端面。光学透明体元件202具有透明体元件前端面、透明体元件后端面。第一固态光源103设于光学透明体元件202的透明体元件后端面处，光线提取器105设于发光晶体元件201的晶体元件前端面处，且光线提取器105有部分覆盖于光学透明体元件202的透明体元件前端面处。第一固态光源103发出的光线通过光学透明体元件202射向光线提取器105，光线提取器105提取从发光晶体元件201和光学透明体元件202射出的光线并进行混光、混色、聚光后射出。
发光晶体元件201可以由单个发光晶体101组成或由多个顺序摆放的发光晶体101组成，光学透明体元件202可以由光学透明体102组成或由光学透明体102与发光晶体101顺序摆放组成。在图1所示的实施例中，发光晶体元件201由单个发光晶体101组成，光学透明体元件202单个由光学透明体102组成。在其它实施例中，发光晶体元件201还可以由多个发光晶体101顺序摆放组成，光学透明体元件202还可以由多个光学透明体102顺序摆放组成，或者由光学透明体102与发光晶体101顺序摆放组成。

第二固态光源104设于发光晶体101的侧面，用于对发光晶体101输出激发光线。第二固态光源104对发光晶体101的晶体侧面输出特定波长范围的激发光线， 发光晶体101吸收该特定波长范围的激发光线后，在其内部发出不同波长范围的光线，同时由于发光晶体101的折射率较高，大部分的光线在发光晶体101内部以全反射的方式进行传播并最终从晶体前端面和晶体后端面输出。发光晶体101的形状设置为长条柱状，可以在发光晶体101的晶体侧面放置较多的第二固态光源104，这些第二固态光源104所组成的光学扩展量要远远大于晶体前端面处的光学扩展量，从而把原本由大量固态光源所组成的非常大的光学扩展量转化为较小的光学扩展量。第一固态光源103、第二固态光源104优选为LED光源或激光光源。
本实施例提供的一种发光装置，采用的光线提取器105可以为光学元件。光学元件优选为导光棒、聚光器或透镜。
本实施例提供的一种发光装置，采用的发光晶体101与光学透明体102可以等长或不等长。

例如，最上层的发光晶体101吸收其晶体侧面的第二固态光源104发出的波长为320nm-520nm的光线，在其内部发出波长为460nm-700nm的光线。这些光线中的部分光线通过发光晶体101内部的全反射射向光线提取器105。中间层的光学透明体元件202的透明体元件后端面处的第一固态光源103发出主波长为455nm的光线，这些光线通过光学透明体元件202也射向光线提取器105。最下层光学透 明体元件202的透明体元件后端面处的第一固态光源103发出主波长为630nm的光线，这些光线通过光学透明体元件202也射向光线提取器105。最后这几种光线由光线提取器105提取并输出。
图4为本发明一种发光装置第一实施例的另一剖面结构示意图。如图4所示，发光装置包括单个发光晶体元件201与两个光学透明体元件202，两个光学透明体元件202并列摆放于发光晶体元件201的下方。发光晶体元件201由两个顺序摆放的发光晶体101组成，光学透明体元件202都由单个光学透明体102组成。发光晶体101的侧面设有第二固态光源104，用于激发发光晶体101。两个光学透明体102的透明体后端面处均设有第一固态光源103，第一固态光源103发出的光线通过光学透明体102射向光线提取器105，这两种光线由光线提取器105提取并输出。
在该实施例中，发光晶体元件由多个发光晶体101组成，多个发光晶体101可以产生多个不同波长范围的光线，发光装置包括多个第一固态光源103，多个第一固态光源103可以发出多个不同波长范围的光线，提取器可以据此提取并输出这些不同波长范围的光线，从而进一步提高了发光装置的色域，丰富了发光装置的发光效果。
例如，最上层的发光晶体元件201中左侧的发光晶体101吸收在其晶体侧面的第二固态光源104发出的波长为320nm-520nm的光线，在其内部发出波长大于480nm的光线。最上层的发光晶体元件201中右侧的发光晶体101吸收在其晶体侧面的第二固态光源104发出的波长为320nm-400nm的光线，在其内部发出波长为350nm-550nm的光线。这些光线中的部分光线通过发光晶体101内部的全反射射向光线提取器105。中间层的光学透明体元件202的透明体元件后端面处的第一固态光源103发出主波长为630nm的光线，这些光线通过光学透明体元件202也射向光线提取器105。最下层光学透明体元件202的透明体元件后端面处的第一固态光源103发出主波长为455nm的光线，这些光线通过光学透明体元件202也射向光线提取器105。最后这几种光线由光线提取器105提取并输出。
图5为本发明一种发光装置第一实施例的另一剖面结构示意图。如图5所示，发光装置包括单个发光晶体元件201与单个光学透明体元件202，光学透明体元件202并列摆放于发光晶体元件201的下方。发光晶体元件201由单个发光晶体101组成，光学透明体元件202由单个光学透明体102和单个发光晶体101顺序摆放组 成。发光晶体101的侧面设有第二固态光源104，用于激发发光晶体101。光学透明体102的透明体后端面处设有第一固态光源103，第一固态光源103发出的光线通过光学透明体102射向光线提取器105，这两种光线由光线提取器105提取并输出。
在该实施例中，光学透明体元件202由单个光学透明体102和单个发光晶体101顺序摆放组成，发光晶体可以产生更多不同波长范围的光线，提取器可以据此提取并输出更多不同波长范围的光线，从而进一步提高了发光装置的色域，丰富了发光装置的发光效果。

图6为本发明一种发光装置第一实施例的另一剖面结构示意图。如图6所示，发光装置包括单个发光晶体元件201与单个光学透明体元件202，光学透明体元件202并列摆放于发光晶体元件201的下方。发光晶体元件201由两个顺序摆放的发光晶体101组成，光学透明体元件202由单个光学透明体102和单个发光晶体101顺序摆放组成。发光晶体101的侧面设有第二固态光源104，用于激发发光晶体101。光学透明体102的透明体后端面处设有第一固态光源103，第一固态光源103发出的光线通过光学透明体102射向光线提取器105，这两种光线由光线提取器105提取并输出。
在该实施例中，与图5所示的实施例相比，发光晶体元件由多个发光晶体101组成，多个发光晶体101可以产生多个不同波长范围的光线，提取器可以据此提取 并输出更多不同波长范围的光线，从而提高了发光装置的色域，丰富了发光装置的发光效果。
例如，上层的发光晶体元件201中左侧的发光晶体101吸收在其晶体侧面的第二固态光源104发出的波长为320nm-520nm的光线，在其内部发出波长大于480nm的光线。上层的发光晶体元件201中右侧的发光晶体101吸收在其晶体侧面的第二固态光源104发出的波长为320nm-400nm的光线，在其内部发出波长为350nm-550nm的光线。这些光线中的部分光线通过发光晶体101内部的全反射射向光线提取器105。下层的光学透明体元件202中的发光晶体101吸收在其晶体侧面的第二固态光源104发出的波长为320nm-400nm的光线，在其内部发出波长为350nm-550nm的光线，其中一部分光线通过发光晶体101内部的全反射射向光线提取器105。下层的光学透明体元件202的透明体元件后端面处的第一固态光源103发出主波长为630nm的光线，这些光线通过光学透明体102射向发光晶体101。同时由于这些主波长为630nm的光线不会被发光晶体101所吸收，因此这些光线能够通过发光晶体101射向光线提取器105。最后这几种光线由光线提取器105提取并输出。
图7为本发明一种发光装置第一实施例的另一剖面结构示意图。如图7所示，发光装置包括单个发光晶体元件201与单个光学透明体元件202，光学透明体元件202并列摆放于发光晶体元件201的下方。发光晶体元件201由两个顺序摆放的发光晶体101组成，光学透明体元件202由单个发光晶体101和单个光学透明体102顺序摆放组成。发光晶体101的侧面设有第二固态光源104，用于激发发光晶体101。光学透明体元件202的透明体元件后端面处设有第一固态光源103，光学透明体元件202中的发光晶体101设于光学透明体102与第一固态光源103之间。第一固态光源103发出的光线通过光学透明体102射向光线提取器105，这两种光线由光线提取器105提取并输出。
在该实施例中，与图6所示的实施例相比，光学透明体元件202中发光晶体101和光学透明体102的位置发生了变化，使得发光装置的结构更加灵活。
例如，上层的发光晶体元件201中左侧的发光晶体101吸收在其晶体侧面的第二固态光源104发出的波长为320nm-520nm的光线，在其内部发出波长大于480nm的光线。上层的发光晶体元件201中右侧的发光晶体101吸收在其晶体侧面 的第二固态光源104发出的波长为320nm-400nm的光线，在其内部发出波长为350nm-550nm的光线。这些光线中的部分光线通过发光晶体101内部的全反射射向光线提取器105。下层的光学透明体元件202中的发光晶体101吸收在其晶体侧面的第二固态光源104发出的波长为320nm-400nm的光线，在其内部发出波长为350nm-550nm的光线，其中一部分光线通过发光晶体101内部的全反射射向光学透明体102并通过光学透明体102射入光线提取器105。下层的光学透明体元件202的透明体元件后端面处的第一固态光源103发出主波长为630nm的光线，由于这些主波长为630nm的光线不会被发光晶体101所吸收，因此这些光线可以通过发光晶体101射向光学透明体102并最终射向光线提取器105。最后这几种光线由光线提取器105提取并输出。
第二实施例
图8为本发明一种发光装置第二实施例的一剖面结构示意图。如图8所示，本实施例提供的一种发光装置中，第一固态光源103与光学透明体元件202的透明体元件后端面之间设有光学零件203，光学零件203用于聚光或用于准直和聚光。例如当第一固态光源103为激光光源或单个LED光源时，光学零件203可以是用于聚光的光学零件，当第一固态光源103为多个LED光源时，光学零件203可以是用于准直和聚光的光学零件。由于使用了用于聚光或用于准直和聚光的光学零件，使得光学透明体元件202的横截面变得更小，同时又不损失太多从第一固态光源103发出的光线，既优化了整个发光装置的光学扩展量，又能保持发光效率。光学零件203优选为导光棒、聚光器或透镜。
第三实施例
图9为本发明一种发光装置第三实施例的一剖面结构示意图，图10为本发明一种发光装置第三实施例的另一剖面结构示意图。如图9-10所示，本实施例提供的一种发光装置还包括反光面301。反光面301设于发光晶体元件201的晶体元件后端面处，以反光面301对发光晶体元件201内部反射至晶体元件后端面的光线进行再次反射，使绝大部分光线能够从发光晶体元件201的晶体元件前端面输出，然后射入光线提取器105，可以降低光的损失，提高出光效率。
