具体实施方式
当结合附图时，鉴于以下详细说明，本公开的上述和其他方面、特征和优势将变得更为显而易见。
此后参照附图描述本公开的具体实施例；然而，应当理解，所申请的实施例仅仅是本公开的实例，其可采用多种方式实施。熟知和/或重复的功能和结构并未详细描述以避免不必要或多余的细节使得本公开模糊不清。因此，本文所申请的具体的结构性和功能性细节并非意在限定，而是仅仅作为权利要求的基础和代表性基础用于教导本领域技术人员以实质上任意合适的详细结构多样地使用本公开。
本说明书可使用词组“在一种实施例中”、“在另一个实施例中”、“在又一实施例中”或“在其他实施例中”，其均可指代根据本公开的相同或不同实施例中的一个或多个。
本公开的实施例提供了一种用于经颅光调控的发光装置，用于向使用者头部发射低功率红色光或近红外光，所发射的光例如可以采用1-500mw的功率级和600-1100nm的波长，来刺激使用者的脑部以产生生物反应并改善脑功能。该发光装置可以如图1所示，主要包括：光源部10、设置在光源部的出射侧上的透光层20以及导光件30，具体地，导光件30的一端(例如图1(a)中所示的下端)固定在透光层20的与光源部10相对的一侧(例如图1(a)中所示的上侧)上，且构造为引导从透光层20透射的光。通过透光层20能够让光源部10发射的光顺利透过，并将光源部10与外部环境进行隔绝，从而降低外部环境对光源部10的影响，也能够减少光源部10向头部侧传递热量，从而避免因为光源部10的温度上升导致的头部不适甚或对生理信号的干扰(例如血氧信号)。配合导光件30的引入，可以提高光传输效率并校正光传输方向，进一步降低光的耗散率并提高发射光在经颅光调控上的利用效率。在佩戴到头部时，透光层20可以向导光件30施加压力使得导光件30能够抵靠头部从而提高对于头部的照射效率。
应当注意的是，图1(a)仅仅是发光装置的一种优选结构示意图，在实际使用时可能根据各个构件的实际结构不同而不同，本实施例不进行限制。
在一些实施例中，导光件30可以设计为柱状，优选为圆柱形，如此可以更好地利用空间。优选使用玻璃或亚克力等无色透明的材质制作导光件30，以确保光线传输效率。具体地，导光件30可以具有固定端31和自由端32，固定端31为导光件30固定在透光层20的一端，自由端32则为导光件30与固定端31相对的另一端。导光件30可以直接与使用者的头皮接触，其构造为传导并出射从透光层20透射出的光，将光直接引导至使用者的头皮，降低头发遮挡对光传输效率的影响。
在一些实施例中，在透光层20上设置的导光件30可以为多个，彼此间隔地布置在透光层20的中心线两侧或者周围。如此，导光件30排布为阵列，起到类似梳齿的作用，有利于增加发光装置与使用者头皮之间的接触点，且梳开头发并使之汇集在导光件30之间的间隔空间内，减少了头发对光照的遮挡作用。在一些实施例中，透光层20的材质可具有弹性，如此导光件30在受到来自头皮的压力时，其角度会发生变化，如此便利导光件30在头发之间的缝隙中穿行并抵靠头皮，进一步减少了头发对光照的遮挡作用。
在一些实施例中，多个导光件30可以构造为随着远离透光层20的中心线而逐渐增加导光件30的长度。也就是说，使多个导光件30的自由端32所组成的面是一个向固定端31凹下的曲面，在导光件30采用多层圈的布置方式时，从外圈至内圈的长度是逐渐减小的。如此，在导光件30受到与透光层20相对的一侧(头部侧)上的外力作用时，这种逐渐变化的长度布置进一步便利导光件30相对于透光层20的中心线向外侧扩展开，从而进一步拨开发光装置下方的头发，进而进一步降低由于头发遮挡所引起的负面影响。此外，这种导光件30的头部侧的凹形曲面布置，更贴合使用者的头部形状，佩戴时更加舒适，与头皮的贴合度更好。
本实施例中的光源部10主要用于发出低频率的近红外光，其波长范围为600纳米至1100纳米，在实际使用时可以根据生产需求使用LED灯泡、激光灯泡或其他能发出近红外光的灯泡。光源部10可以是上述任意一种灯 泡，或者将多个灯泡置于一个电路板上，形成光源层进行使用，图1(a)中示出的光源部10即为具有多个灯泡的电路板形成的光源层。
图1(b)示出根据本公开另一实施例的用于经颅光调控的发光装置的结构示意图，此处省略对图1(a)中相似构件的描述以避免冗余。如图1(b)所示，发光装置还可以包括弹性构件40，其连接到光源部10的与透光层20相对的一侧(图1(b)中的下侧)上。该弹性构件40可以采用各种实现方式，包括但不限于弹簧、弹性材料层等，以使得光源部10、透光层20和导光件30构成的部分在来自头部的压力作用下能够发生伸缩，进一步提升了发光装置对于不同使用者头部形状的适配性。
为了减少外部环境对发光装置的影响，并保护发光装置中各个构件，发光装置还可以具有外壳50，外壳50用于容纳光源部10、透光层20以及弹性构件40，使光源部10、透光层20以及弹性构件40在导光件30的自由端32受到外力作用时，基于弹性构件40的可伸缩特性，在外壳50内部进行移动。同时，外壳50还具有第一开口，固定在透光层20上的导光件30则从第一开口中伸出。如此，可以约束在弹性构件40作用下的伸缩方向，减少光源部10、透光层20和导光件30的晃动。
在一些实施例中，弹性构件40的与光源部10相对的一端(图1(b)中为远离头部侧即下侧)还可以连接有散热层60，用于对光源部10进行散热，散热层60固定在外壳50内，保证发光装置在工作的温度不会过高，散热层60具体的散热方式可以为风冷或水冷，即使用风扇或水冷散热器进行实现。散热层60设置在远离头部侧，能够避免各种散热机制给头部带来不适甚或对头部生理信号的干扰(例如血氧信号)。
图2示出了根据本公开实施例的用于经颅光调控的设备的结构示意图。如图2所示，该经颅光调控的设备包括佩戴装置100和承载装置200。佩戴装置100构造为供使用者佩戴到头部，该佩戴装置100可以为头盔、头箍或弹性头帽(如图2所示)等。
如图2所示，承载装置200上固定有根据本公开各个实施例的发光装置300。虽然图2中示出了圆形结构的发光装置300，实际使用时可自行选择发光装置300的形状和大小。图2中的佩戴装置100为弹性头帽，因其具有弹性可以配适不同头型，其包括具有弹性的软性头帽主体以及连接在头帽主体上的固定带101，固定带101用于在使用者佩戴弹性头帽时将弹 性头帽固定在使用者下颚或者面颊处，其可以为绑带或具有卡扣的绑带。在一些实施例中，佩戴装置100还可以为由硬质不透明的材料制成的头盔，以增强佩戴装置100的抗冲击能力，且由于其不易变形，可以防止在设备使用过程中因外力干扰所引起的移动等情况出现。优选地，弹性头帽也可以由不透明的材料制成，防止光线外露导致的使用效果降低或光线外露对使用者的眼睛造成伤害。
图3示出了根据本公开实施例的承载装置200的结构示意图。在一些实施例中，该承载装置200主要可以包括底座201和至少一个分支臂202。底座201固定在佩戴装置100上(如图2所示)，例如固定在佩戴装置100的内侧，例如头顶部分；每个分支臂202的一端通过第一偏置构件(图3中未示出)以可枢转的方式与底座201连接，分支臂202可以在第一偏置构件的作用下向内收拢。如此，在分支臂202被头部的外部轮廓扩开的情况下，第一偏置构件施加与之对抗的向内收拢力，从而能够使得分支臂202连同其上布置的发光装置300更牢固紧密地贴合使用者的头部，且能够防止头部晃动导致的分支臂202与头部的脱离。在一些实施例中，第一偏置构件2011可以为弹性关节或扭簧。如图3所示，多个分支臂202可以呈爪型布置，以便更牢固卡紧到头部，且使得散布在各个分支臂202上的发光装置200能够针对性地照射头部的不同区域。
在一些实施例中，分支臂202可以由具有一定弹性的硬质材料制成，其形状可适配使用者头部的形状，使得分支臂202上固定的发光装置300可以按需照射到使用者的细分头部区域，例如但不限于额叶、顶叶、颞叶、枕叶等区域，以实现对应脑功能的针对性光调控效果。
在一些实施例中，分支臂202可以采用分节式布置。也就是说，分支臂202可以具有多个彼此铰接的关节，以实现更灵活的收放操作。如图4和图5所示，该分支臂202可包括上分支臂2021和下分支臂2022，上分支臂2021的一端通过第一偏置构件2011以可枢转方式与底座201连接，下分支臂2022则通过第二偏置构件2023以可枢转方式与上分支臂2021的另一端连接，以便在第二偏置构件2023的作用下，使下分支臂2022向内收拢，以保证用户在佩戴设备时更紧密的贴合，同时可以适配不同使用者的不同头型，提升设备的适配性。虽然图4和图5中示出了双关节布置， 但分支臂202的结构不限于此，只要相邻关节之间是可枢转方式连接且设有相应偏置构件以在无外力作用下保持收拢状态即可。
图4示出了在未受到外力作用时分支臂202在收拢状态下的示意图，图5则示出了在使用者佩戴设备时，在受到外力作用时分支臂202在张开状态下的示意图。
根据本公开各个实施例的经颅光调控设备方便使用者佩戴，且通过设置在承载装置的底座和分支臂之间(以及分支臂的相邻关节之间)的偏置构件，使发光装置可以紧密地贴合在使用者头部，并增强了设备对于不同使用者头部形状的适配性，结合发光装置的导光布置进一步减小了使用者头发对光线的遮挡问题，增强了设备的使用效果。
图6示出了一种用于经颅光调控的系统，该系统包括：根据本公开各个实施例的用于经颅光调控的设备500、至少一个检测装置以及终端600。其中，用于经颅光调控的设备500主要用于向使用者发射近红外光；检测装置则固定在设备的承载装置上(图6中未示出)，用于采集使用者脑部经近红外光照射后的生理信号；终端600可以为独立于经颅光调控设备500的独立设备，用于接收检测装置采集的生理信号并进行数据分析，以便使用者获悉自身使用情况，终端600还可根据数据分析的结果通过发送相应的控制信号来进行发光装置和检测装置的自动控制。
检测装置可以类似于发光装置由承载装置的分支臂承载，使用者可以根据需要选择其中的几个分支臂承载检测装置。在一些实施例中，检测装置可以采用各种生理传感器、探头、探针、电极等。检测装置可以根据具体需求和应用场景来选择，例如，在需要测量大脑节律时，可以选择EEG来测量脑电，需要测量大脑区域的活跃程度时，可以选择fNIRS来测量血氧信号。相应地，检测装置可以为脑电图描记器(EEG，electro encephalo graph)或近红外光脑功能成像(fNIRS，functional near-infrared spectroscopy)等的信号采集装置，包括但不限于电极、探头等。在检测装置中，检测探头的位置可以根据使用者的需要来进行设置或更改，这些检测点可以是从国际10-20脑电系统规定的点中选取，也可以按照使用者感兴趣的点来进行选取。检测装置采集到的脑电信号或血氧信号可以传送至终端，由终端对脑电信号或血氧信号进行分析。
图7(a)示出了根据本公开实施例的用于经颅光调控的系统中的终端600的单元示意图。如图7(a)所示，该终端600可以包括发光控制单元601、检测控制单元602以及数据分析单元603。发光控制单元601可以配置为用于控制各个发光装置的开启定时以及发光强度，例如根据使用者的实际需求，对应控制不同位置的发光装置的开启，调整各个发光装置的光源部的开启时间以及开启频率；检测控制单元602被配置为用于控制各个检测装置的开启定时和/或开启频率，具体地，检测控制单元602可根据发光控制单元601控制发光装置开启的情况，对应设置检测装置的开启时间和开启频率，或选择具体使用何种采集装置进行检测；数据分析单元603被配置为基于所接收的检测装置采集的生理信号进行数据分析，并可具体将数据分析的结果馈送到发光控制单元601和检测控制单元602中的至少一个，对应地，发光控制单元601和检测控制单元602中的至少一个可以基于数据分析的结果调整对于相应装置的控制信号。
在一些实施例中，使用者每次进行训练前可以设置一训练目标，即使用者希望获取到的训练效果，在训练过程中，若使用者的生理信号经过数据分析单元603数据分析后其分析的结果已经满足训练目标，则发光控制单元601或检测控制单元602可根据该结果调整对于相应装置的控制信号为关闭的控制信号，对应关闭发光装置或检测装置，证明训练完成。发光控制单元601或检测控制单元602还可根据数据分析的结果进行其他调整，如根据当前的数据分析结果，与训练目标进行对比，并根据对比结果调整发光装置或检测装置的开启时间、开启强度等参数，实现更优的训练效果。
图7(b)示出了根据本公开实施例用于经颅光调控的系统中的终端600的配置框图。如图7(b)所示，终端600可以包括：通信接口606，其配置为获取检测装置采集的使用者脑部的生理信号；以及处理器604，其配置为控制各个发光装置和检测装置，并基于使用者脑部的生理信号进行数据分析。
