Description

技术领域
本发明涉及一种信号发射装置, 特别是涉及一种非可见光发射装 置。 背景技术
近年来, 由于现代科技的发展迅速, 更方便医疗界将声、 光、 热、 电、 磁以及放射线等各种物理能量普遍运用在医疗行为上, 其中采用 属于非可见光的远红外线(Far Infrared Light, FIR Light)来进行物理治 疗的方法也愈来愈常见。
自然界存在有可以自然产生此类属于非可见光的远红外线辐射的 材料 (例如: 远红外线陶瓷材料:), 这些物质的远红外线辐射强度和物质 特性及其表面温度有关。 相同材质的条件下, 表面温度越高, 产生的 远红外线辐射强度也越强。 已知技术的远红外线发射源可分为无加热 式和加热式等两大类。 无加热式的远红外线发射源, 其远红外线产生 材料是以室温或是依附的人体体温为能量基础, 由于温度不高, 因此 仅能激发出微弱的远红外线。 加热式的远红外线发射源, 通常藉由电 热元件的传导加热, 提升远红外线陶瓷材料的表面温度, 产生足够辐 射强度的远红外线。 例如, 以电热丝或是发热电阻薄膜包覆于远红外 线陶瓷材料之内。
然而, 由于电热丝加热或是发热电阻薄膜加热是以传导的方式进 行导热, 与利用热辐射的加热方式相比较, 电热丝使用热传导的加热 方式其加热速率明显比较慢。 此外, 一般以热传导方式导热的电热丝 的使用寿命约为数千小时, 与可以产生红外线热辐射的发光二极管具 有数万小时寿命相比较, 电热丝的使用寿命明显较短。 而且, 热辐射 线以及远红外线都是属于光线, 但现有技术无法有效聚集光线。 发明内容
本发明的目的在于提供一种非可见光发射装置, 其不仅具有较长 的使用寿命与较快的非可见光产生速率, 而且可以控制非可见光发射 的区域辐射强度。
本发明所提供的非可见光发射装置包括热辐射发射元件以及光转 换元件, 其中热辐射发射元件适于提供第一非可见光与热能, 光转换 元件覆盖热辐射发射元件的出光面。 光转换元件包括第一透光体及配 置于第一透光体内的光转换材料。 光转换材料用以吸收热辐射发射元 件产生的第一非可见光与热能, 并发出第二非可见光。 此非可见光发 射装置, 不仅具有比较快的第二非可见光产生速率与比较长的使用寿 命, 而且可以控制第二非可见光发射的区域辐射强度。
在本发明的一实施例中, 上述的非可见光发射装置更包括基板, 该基板具有相对的第一表面与第二表面, 其中热辐射发射元件与光转 换元件设置在第一表面上。
在本发明的一实施例中, 上述的非可见光发射装置更包括第二透 光体, 该第二透光体配置在基板的第一表面上, 并覆盖光转换元件。 在本发明的一实施例中, 上述的非可见光发射装置更包括第二透 光体, 该第二透光体配置在基板的第一表面上, 且位于热辐射发射元 件与光转换元件之间。
在本发明的一实施例中, 上述的非可见光发射装置更包括散热元 件, 该散热元件设置于基板的第二表面。
在本发明的一实施例中, 上述的散热元件包括热转换材料, 该热 转换材料用以吸收热能并辐射出第三非可见光。
在本发明的一实施例中, 上述的第一非可见光包括近红外光, 第 二非可见光及第三非可见光包括远红外光。
在本发明的一实施例中, 上述的第一非可见光包括近红外光, 第 二非可见光包括远红外光。
在本发明的一实施例中,上述的第一非可见光波长范围介于 700〜 1400纳米 (; nm), 第二非可见光波长范围介于 4〜1000微米 (; m)。
在本发明的一实施例中, 上述的光转换材料成点状分佈于第一透 光体内。
在本发明的一实施例中, 上述的热辐射发射元件包括发光二极管 (Light Emitting Diode,; LED)。
在本发明的一实施例中, 上述的光转换材料为远红外线辐射材料 (Far-Infrared Radiation Material)。
在本发明的一实施例中, 上述的热辐射发射元件更提供热能, 该 热能经由第一透光体传导至光转换材料, 光转换材料用以吸收热能, 并发出第二非可见光。 本发明的非可见光发射装置以热辐射发射元件发射出第一非可见 光与热能。 第一非可见光可透过第一透光体以热辐射方式传递至光转 换材料, 而热能也可藉由光转换元件内的第一透光体以热传导的方式 传递至光转换元件内的光转换材料, 光转换材料吸收第一非可见光及 热能后, 造成内部分子震动进行能量转换, 进而发射出第二非可见光。 由于本发明以热辐射与热传导兼具的方式取代现有的热传导方式加热 光转换材料, 因此本发明不仅具有比较快的第二非可见光产生速率与 比较长的使用寿命, 而且可以藉由第一透光体的光学设计控制第二非 可见光发射的区域辐射强度。
为让本发明的上述和其他目的、 特征和优点能更明显易懂, 下文 特举较佳实施例, 并配合所附图式, 作详细说明如下。 附图说明
图 1是本发明一实施例的一种非可见光发射装置示意图。
图 2是本发明另一实施例的一种非可见光发射装置示意图。
图 3是本发明又一实施例的一种非可见光发射装置示意图。 具体实施方式
以下将以远红外光发射装置为例来对本发明的非可见光发射装置 做详细的说明。 需注意的是, 本发明的非可见光发射装置并非限定于 远红外光发射装置。 此外, 本发明中的热辐射发射元件并非限定于近 红外光发光二极管。
图 1是本发明一实施例的非可见光发射装置示意图。 请参照图 1, 本实施例的非可见光发射装置 100包括热辐射发射元件 110以及光转 换元件 120, 其中热辐射发射元件 110适于提供第一非可见光 L1 , 光 转换元件 120覆盖热辐射发射元件 110的出光面 111。 光转换元件 120 包括第一透光体 122及配置在第一透光体 122 内的光转换材料 124。 光转换材料 124用以吸收第一非可见光 L1并发射出第二非可见光 L2。
本实施例的非可见光发射装置 100例如更包括基板 130, 此基板 130具有相对的第一表面 131与第二表面 132,其中热辐射发射元件 110 与光转换元件 120设置于基板 130的第一表面 131。 基板 130例如是 电路板, 而热辐射发射元件 110 电性连接至基板 130, 以使基板 130 能驱使热辐射发射元件 110提供第一非可见光 Ll。 本实施例例如是透 过焊线 160来电性连接基板 130与热辐射发射元件 110,但本发明并不 限定基板 130与热辐射发射元件 110的电性连接方式。
在本实施例中, 热辐射发射元件 110例如为近红外光发光二极管, 其提供的第一非可见光 L1例如为波长范围大约介于 700至 1400纳米 (nm)之间的近红外光。 此外, 光转换材料 124例如是以点状分布于第 一透光体 122 内。 光转换材料 124例如为适合的远红外线辐射材料。 光转换材料 124可吸收第一非可见光 L1中的热能并辐射出第二非可见 光 L2。此第二非可见光 L2例如是波长范围大约介于 4至 1000微米 Oim) 之间的远红外光。
在本实施例中, 当驱动热辐射发射元件 110后, 热辐射发射元件
110会发射出第一非可见光 Ll。 由于第一非可见光 L1为近红外光, 其 具有热辐射的特性, 因此可有效带走热辐射发射元件 110所产生的热 量。第一非可见光 LI照射到光转换材料 124后, 光转换材料 124的内 部分子会震动而进行能量转换, 进而发射出第二非可见光 L2。
此外, 在本实施例中, 当驱动热辐射发射元件 110后, 热辐射发 射元件 110更会发射出热能 (图未示:), 利用第一透光体 122作为介质, 以热传导的方式传递至光转换材料 124, 使光转换材料 124进行能量 转换而发射出第二非可见光 L2。 有别于现有技术, 本实施例并非单独 采用热传导的方式对光转换材料 124加热来达到辐射出远红外光的目 的, 而是同时采用热辐射与热传导两种方式, 使光转换材料 124接受 热辐射发射元件 110产生的第一非可见光 L1与热能进行能量转换, 以 发射出第二非可见光 L2。 本实施例具有较快的第二非可见光 L2产生 速率与较长的使用寿命的优点。另外, 本实施例可藉由第一透光体 122 的形状设计来调整非可见光的出光光形, 以符合使用需求。 举例来说, 第一透光体 122 的形状可设计成能汇聚光线的形状, 以使第二非可见 光 L2能聚集于限定范围以加强区域辐射强度。
为了进一步利用非可见光发射装置 100的热能, 可于基板 130的 与第一表面 131相对的第二表面 132设置散热元件 140, 以对热辐射 发射元件 110进行散热。 此散热元件 140例如包括被动式散热件 142, 如散热鳍片。 此外, 为了充分利用热辐射发射元件 110所产生的热能, 散热元件 140 可包括热转换材料 144, 用以吸收传导至被动式散热件 142的热能并辐射出第三非可见光 L3。 热转换材料 144例如为远红外 线辐射材料, 其辐射出的第三非可见光例如是远红外光。 在本实施例 中, 热转换材料 144例如是涂布于被动式散热件 142表面的涂层, 但 本发明并不以此为限。 举例来说, 热转换材料还可以是点状分布于被 动式散热件 142的表面或内部。
图 2是本发明另一实施例的非可见光发射装置示意图。 请参照图 2,本实施例的非可见光发射装置 200与上述实施例的非可见光发射装 置 100 的结构与优点相似, 以下仅针对其结构上差异进行说明。 相较 于上述的非可见光发射装置 100, 本实施例的非可见光发射装置 200 更包括第二透光体 250, 配置在基板 130的第一表面 131 上, 并覆盖 光转换元件 220。光转换元件 220与上述的光转换元件 110相似,在此 不再重述。 本实施例的第二透光体 250例如为可透光封装材料, 但不 以此为限。 本实施例可藉由第二透光体 250 的形状设计来调整非可见 光的出光光形, 以符合使用需求。 本实施例中, 第二透光体 250例如 为一完全可透光封装材料, 并未包含热转换材料 144。 因此, 可以更 藉由第二透光体 250的形状设计来精确调整第二非可见光 L2的出光光 形, 以符合使用需求。
图 3 是本发明又一实施例的非可见光发射装置示意图。 请参照图 3,本实施例的非可见光发射装置 300与上述实施例的非可见光发射装 置 100的结构与优点相似, 差别处在于非可见光发射装置 300更包括 第二透光体 350, 配置在基板 130 的第一表面 131 上, 且位于热辐射 发射元件 110与光转换元件 320之间。 光转换元件 320与上述的光转 换元件 110相似,在此不再重述。本实施例可以直接使用包含基板 130 与配置在其第一表面 131 上的热辐射发射元件 110和第二透光体 350 的现有成品, 达到提升生产效率与降低生产成本的目的。 综上所述, 由于本发明以热辐射与热传导兼具的方式取代现有的 热传导方式加热光转换材料, 因此本发明不仅具有较快的第二非可见 光产生速率与较长的使用寿命, 而且可以利用光学设计方法决定第二 非可见光的出光面与光形, 将产生的第二非可见光聚集于限定范围, 以加强第二非可见光的区域辐射强度。
虽然本发明已以比较佳实施例揭露如上, 然其并非用以限定本发 明, 任何熟习此技艺者, 在不脱离本发明的精神和范围内, 当可作些 许的更动与润饰, 因此本发明的保护范围当视后附的权利要求范围所 界定者为准。
