示范例中，荧光粉A、荧光粉B、荧光粉C、荧光粉D1、荧光粉D2、荧光粉D3、荧光粉E1、荧光粉E2和荧光粉F独立的可以是但不限于(Ca,Sr)AlSiN3(钙锶铝硅氮三，1113)或K2SiF6:Mn4+(氟硅酸钾)。另外，各发光波长的荧光粉如荧光粉A、荧光粉B、荧光粉C、荧光粉D1、荧光粉D2、荧光粉D3、荧光粉E1、荧光粉E2和荧光粉F可以根据发光波长直接市购获得。
需要说明的是，荧光粉A、荧光粉B、荧光粉C、荧光粉D1、荧光粉D2、荧光粉D3、荧光粉E1、荧光粉E2或荧光粉F中的任一荧光粉具体包括几种化合物并不限定，其可以是仅包括一种单一化合物纯净物，也可以是包括多种化合物混合物。
当然了，第一荧光粉所含的荧光粉D1、第二荧光粉所含的荧光粉D2和第三荧光粉所含的荧光粉D3的具体发光波长可以相同，例如荧光粉D1、荧光粉D2和荧光粉D3的发光波长均为720nm。荧光粉D1、荧光粉D2和荧光粉D3的发光波长也可以不相同，例如荧光粉D1、荧光粉D2和荧光粉D3的发光波长分别为715nm、720nm、和725nm。当荧光粉D1、荧光粉D2和荧光粉D3的发光波长相同时，荧光粉D1、荧光粉D2和荧光粉D3可以为相同的物质，例如荧光粉D1、荧光粉D2和荧光粉D3都是(Ca,Sr)AlSiN3，荧光粉D1、荧光粉D2和荧光粉D3也可以为不相同的物质，例如荧光粉D1为(Ca,Sr)AlSiN3，荧光粉D2和荧光粉D3为K2SiF6:Mn4+。同理，荧光粉E1和荧光粉E2的具体发光波长可以相同，也可以不同，当荧光粉E1和荧光粉E2的发光波长相同时，荧光粉E1和荧光粉E2可以是相同物质，也可以是不同的物质。
在一些实施例中，可以控制第一荧光粉中荧光粉A、荧光粉B和荧光粉D1之间的质量比为(3～25)：(3～35)：(5～50)，进一步为(5～20)：(5～25)：(10～40)，更 进一步为(5～15)：(5～20)：(10～30)。
在一些实施例中，可以控制第二荧光粉中荧光粉C、荧光粉D2和荧光粉E1之间的质量比为(7～35)：(7～40)：(10～50)，进一步为(10～30)：(10～35)：(15～40)，更进一步为(10～25)：(10～30)：(20～40)。
在一些实施例中，可以控制第三荧光粉中荧光粉D3、荧光粉E2和荧光粉F之间的质量比为(10～40)：(10～40)：(15～50)，进一步为(12～35)：(12～35)：(15～40)，更进一步为(15～30)：(15～30)：(15～35)。
将荧光粉A、荧光粉B和荧光粉D1的质量比，荧光粉C、荧光粉D2和荧光粉E1的质量比，以及荧光粉D3、荧光粉E2和荧光粉F的质量比控制在该范围内，能够对本申请实施例红光荧光组合物所产生的红光的光强、波峰平坦程度、波峰的波长和的波峰的宽窄程度进行调整，使得该红光的光谱中波峰更为平坦，波峰更宽，以进一步扩宽红光的有效波长，提高红光的理疗效果。同时，在该范围内，还可以通过调节其中一种或几种一荧光粉的比例，以提高红光中具体的一个或几个波长的光功率，使该波长的光功率凸出于其他波长，以提高该波长的红光的光疗效果或作用，例如，通过调节荧光粉的比例，令红光荧光组合所产生的红光中，波长为650nm处的红光具有比其他波长下的红光更高的光功率，使得本申请实施例红光荧光组合物所产生的红光更有利于人体创伤组织的愈合。
在一些实施例中，可以控制第一荧光粉、第二荧光粉和第三荧光粉的粒径独立的小于或等于50μm，进一步可以为5μm～50μm，更进一步可以为10μm～50μm。控制第一荧光粉、第二荧光粉和第三荧光粉的粒径在该范围内，使得第一荧光粉、第二荧光粉和第三荧光粉的颗粒具有更大的比表面积，进而提高发光效率。同时在第一荧光粉、第二荧光粉和第三荧光粉与成膜材料成膜时，第一荧光粉、第二荧光粉和第三荧光粉的颗粒与成膜材料具有更好的相容性，进而使得膜厚更薄。
本申请实施例第二方面提供一种红光荧光膜，本申请实施例红光荧光膜包括第一荧光膜、第二荧光膜和第三荧光膜。其中，第一荧光膜包括第一成膜材料和分散在第一成膜材料中的上文本申请实施例红光荧光组合物所含的第一荧光粉，第二荧光膜包括第二成膜材料和分散在第二成膜材料中的上文本申请实施例红光荧光组合物所含的第二荧光粉，第三荧光膜包括第三成膜材料和分散在第三成膜材料中的上文本申请实施例红光荧光组合物所含的第三荧光粉。
本申请实施例红光荧光膜包括上述本申请实施例的红光荧光组合物，使得本申请实施例的红光荧光膜能够被光子激发产生宽谱的红光，且该红光的光谱图中，波峰前后较宽的波段内峰形平坦，该波段是有效波段，该波段范围内的红光的光功率和能量密度相近，均能产生理疗效果。进而使得本申请实施例的红光荧光膜所产生的红光理疗的有效波段宽，理疗效果好。
在一些实施例中，本申请实施例中第一荧光膜、第二荧光膜和第三荧光膜可以依次层叠设置，也可以分开单独设置。例如一些具体示范例中，第一荧光膜、第二荧光膜和第三荧光膜分别单独设置。另一些示范例中，第一荧光膜和第二荧光膜层叠设置形成含有双层膜层的第四荧光膜，并与第三荧光膜分开设置。
通过第一荧光膜、第二荧光膜和第三荧光膜单独分别包括第一荧光粉、第二荧光粉和第三荧光粉，使得红光荧光组合物在使用时，无需将第一荧光粉、第二荧光粉和第三荧光粉按比例进行混合，而使得第一荧光粉、第二荧光粉和第三荧光粉的比例可以在红光荧光膜的制备时根据需求进行灵活的调整。同时还可以分别对第一荧光膜、第二荧光膜和第三荧光膜的膜厚以及荧光粉的浓度进行调整，以进一步优化光效。
在一些实施例中，第一成膜材料、第二成膜材料和第三成膜材料独立的可以包括硅胶和环氧树脂中至少一种。该些材料如硅胶具有良好的透光性、抗大气老化和抗紫外老化等优异性能，使得红光荧光膜具有良好的透光性且不易因使用过程中的老化而变黄。
另外，第一成膜材料、第二成膜材料和第三成膜材料可以相同，例如，具体示范例中，第一成膜材料、第二成膜材料和第三成膜材料都是硅胶；第一成膜材料、第二成膜材料和第三成膜材料也可以不相同，例如，在另一些具体示范例中，第一成膜材料为硅胶，第二成膜材料和第三成膜材料均为环氧树脂。
在一些实施例中，可以控制第一荧光膜中的第一荧光粉、第二荧光膜中的第二荧光粉和第三荧光膜中第三荧光粉的质量比为(5～30)：(10～40)：(15～60)，进一步为(7～25)：(12～30)：(17～50)，更进一步为(10～20)：(15～25)：(20～40)。通过控制第一荧光粉、第二荧光粉和第三荧光粉的质量比在该范围内，进一步提高本申请实施例红光荧光膜所产生红光的光谱图中波峰前后峰形的平坦性，扩大红光理疗的有效波段，提高理疗效果。
在一些实施例中，第一荧光膜、第二荧光膜和第三荧光膜中任一荧光膜可以为一层单膜，这样，可以使得第一荧光膜、第二荧光膜和第三荧光膜的膜厚更薄。在进一步实施例中，还可以控制第一荧光膜、第二荧光膜和第三荧光膜膜厚为亚毫米级别，如0.06mm～0.60mm，以提高光效。
在一些实施例中，第一荧光膜包括多个单膜层，多个单膜层层叠结合形成复合膜。如在示范例中，第一荧光膜是由膜层A、膜层B和膜层D1复合形成的复合膜，其中，膜层A包含荧光粉A，膜层B包含荧光粉B，膜层D1包含荧光粉D1。制备时，可以通过压膜法分别单独制备膜层A、膜层B和膜层D1，再将膜层A、膜层B和膜层D1依次层叠，真空压合形成第一荧光膜，也可以通过喷膜形成膜层A，在膜层A上再进行喷膜形成膜层B，最后在膜层A和膜层B的基础上再次喷膜形成膜层D1，使得膜层A、膜层B和膜层D1复合形成第一荧光膜。
在一些实施例中，第二荧光膜包括多个单膜层，多个单膜层之间层叠结合，复合形成第二荧光膜，其中，第二荧光膜中多个单膜层之间的结合方式可以与第一荧光膜的多个单膜层结合方式相同。
在一些实施例中，第三荧光膜包括多个单膜层，多个单膜层之间层叠结合，复合形成第三荧光膜，其中，第三荧光膜中多个单膜层之间的结合方式可以与第一荧光膜的多个单膜层结合方式相同。
通过多个单膜层分别复合形成第一荧光膜、第二荧光膜和第三荧光膜，能够在第一荧 光膜、第二荧光膜和第三荧光膜的制备时，灵活控制荧光粉的质量比和浓度，进而根据需要调整本申请实施例红光荧光膜所产生的红光，例如，可以控制第一荧光粉中荧光粉A、荧光粉B和荧光粉D1的质量比和浓度。
在一些实施例中，可以控制第一荧光膜中第一荧光粉的浓度为40％～87％，进一步为50％～80％，更进一步为60％～75％。其中，第一荧光粉的浓度为第一荧光粉的质量在第一荧光粉和第一成膜材料总质量中的占比。
在一些实施例中，可以控制第二荧光膜中第二荧光粉的浓度为30％～87％，进一步为40％～80％，更进一步为60％～75％。其中，第二荧光粉的浓度为第二荧光粉的质量在第二荧光粉和第二成膜材料总质量中的占比。
在一些实施例中，可以控制第三荧光膜中第三荧光粉的浓度为30％～87％，进一步为45％～80％，更进一步为60％～75％。其中，第三荧光粉的浓度为第三荧光粉的质量在第三荧光粉和第三成膜材料总质量中的占比。
第一荧光粉、第二荧光粉和第三荧光粉的浓度对本申请实施例红光荧光膜所产生的红光光功率产生明显的影响，浓度越大，所产生的红光光功率越大。控制第一荧光粉、第二荧光粉和第三荧光粉的浓度在该范围内，能够调整红光荧光膜所发出的红光的光功率，以提高了红光的理疗效果。
可以理解的是，本申请实施例红光荧光膜可以采用压膜法和/或喷膜法成膜。
在一些实施例中，本申请实施例红光荧光膜采用压膜法成膜，可以控制第一荧光膜、第二荧光膜和第三荧光膜中任一荧光膜的膜厚为0.06mm～0.6mm。
在一些实施例中，本申请实施例红光荧光膜采用喷膜法成膜，可以控制第一荧光膜、第二荧光膜和第三荧光膜中任一荧光膜的膜厚为0.001mm～0.01mm，进一步为0.002mm～0.006mm，更进一步为0.002mm～0.003mm。
将本申请实施例红光荧光膜的膜厚控制在该范围，几乎接近于红光荧光组合物颗粒的粒径，使得该红光荧光膜与芯片制成光源后，能够进一步降低芯片产生的激发光在该红光荧光膜中的折射，使得激发光能够最大限度的达到红光荧光组合物颗粒的表面，以最大程度的促进红光荧光组合物被激发产生红光，从而提高光效。需要说明的是，红光荧光膜中的第一荧光膜、第二荧光膜和第三荧光膜的膜厚可以相同，也可以不相同，本领域技术人员可以根据需要或根据光效对膜厚进行调整。
本申请实施例第三方面，提供了一种红光LED光源。本申请实施例的红光LED光源包括发光单元，发光单元包括芯片和设置与芯片光路上的红光荧光膜。其中，该红光荧光膜为上述本申请实施例红光荧光膜，为节约篇幅，在此不再对红光荧光膜进行赘述。
本申请实施例提供的红光LED光源，通过芯片产生激发光，激发设于芯片出光通路的红光荧光膜，以产生宽谱的红光。在该红光的光谱图中，波峰前后较宽的波段内峰形平坦，该波段红光的光功率和能量密度相近，均能产生理疗效果，该波段为理疗有效波段。本申请实施例的红光LED光源，通过芯片激发红光荧光膜，产生的红光有效波段宽，理疗效果 好。
在一些实施例中，本申请实施例的红光LED光源包括多个发光单元，具体可以包括第一发光单元、第二发光单元和第三发光单元三个发光单元。其中，第一发光单元包括第一芯片和设置在第一芯片光路上的上文所述的第一荧光膜，第二发光单元包括第二芯片和设置在第二芯片光路上的上文所述的第二荧光膜，第三发光单元包括第三芯片和设置在第三芯片光路上的上文所述的第三荧光膜。或在另一些实施例中，本申请实施例红光LED光源具体也可以包括第四发光单元和第五发光单元两个发光单元，第四发光单元包括第四芯片和上文所述的第四荧光膜，第五发光单元包括第五芯片和上文所述的第三荧光膜。
通过将第一荧光膜、第二荧光膜和第三荧光膜单独制成不同的发光单元，使得不同发光单元所产生的红光复合形成有效波段宽、理疗效果好的红光。同时能够通过调整不同发光单元所产生的红光的波峰来灵活的调整红光LED光源所产生红光波峰的波长范围和峰形的平坦程度，使得波峰前后波段内的峰形更为平坦，且使该波段下的红光的光功率和能量密度更为接近。
在一些实施例中，第一荧光膜、第二荧光膜和第三荧光膜中任一荧光膜是由多个单膜层复合形成，该多个单膜层按照折射率的从小到大的顺序，依次远离芯片排列，即单膜层的折射率越小，越靠近芯片，单膜层的折射率越大，越远离芯片。通过设置折射率小的膜层靠近芯片，使得光线在光源中的传播为由光疏介质射向光密介质，避免了光线传播时因光线是由光密介质射向光疏介质，光线入射角大于全反射临界角而被反射导致光线无法射出，进而导致红光LED光源亮度低的问题。
在一些实施例中，可以控制第一芯片、第二芯片和第三芯片中任一芯片的发光波长为440nm～475nm，进一步为440nm～460nm，更进一步为452nm～455nm。通过控制芯片的发光波长在该范围内，能够降低435nm～440nm蓝光的光功率，以减少435nm～440nm蓝光对视网膜的伤害。可以理解的是，第一芯片、第二芯片和第三芯片的发光波长可以相同，例如第一芯片、第二芯片和第三芯片的发光波长都是452nm，第一芯片、第二芯片和第三芯片的发光波长也可以不相同，例如第一芯片、第二芯片和第三芯片的发光波长分别为452nm、455nm和458nm，本领域技术人员根据可以根据需求进行设置。
可以理解的是，芯片的发光波长指的是芯片被电流激发，所产生的光的光谱图中，主峰峰值处的波长。
在一些实施例中，本申请实施例红光LED光源中的红光荧光膜采用压膜法制备，可以控制第一荧光膜、第二荧光膜和第三荧光膜中任一荧光膜的膜厚为0.06mm～0.6mm，第一芯片、第二芯片和第三芯片中任一芯片的发光波长均为440nm～475nm。第一荧光膜中，第一荧光粉的浓度为40％～87％，第一荧光粉中，荧光粉A、荧光粉B和荧光粉D1的质量比为(3～25)：(3～35)：(5～50)。第二荧光膜中，第二荧光粉的浓度为40％～87％，第二荧光粉中荧光粉C、荧光粉D2和荧光粉E1的质量比为(7～35)：(7～40)：(10～50)。第三荧光膜中第三荧光粉的浓度为40％～87％，第三荧光粉中，荧光粉D3、荧光粉E2和荧光粉F的质量比为(10～40)：(10～40)：(15～50)。
在进一步实施例中，可以控制第一芯片、第二芯片和第三芯片的发光波长均为 440nm～460nm。第一荧光膜中第一荧光粉的浓度为50％～80％，第一荧光粉中，荧光粉A、荧光粉B和荧光粉D1的质量比为(5～20)：(5～25)：(10～40)。第二荧光膜中第二荧光粉的浓度为50％～80％，第二荧光粉中荧光粉C、荧光粉D2和荧光粉E1的质量比为(10～30)：(10～35)：(15～40)。第三荧光膜中第三荧光粉的浓度为50％～80％，第三荧光粉中，荧光粉D3、荧光粉E2和荧光粉F的质量比为(12～35)：(12～35)：(15～40)。

对比例C2
本对比例提供一种红光LED光源。本对比例的红光LED光源与对比例C1的红光LED光源基本相同，区别在于，本对比例的红光荧光膜为对比例B2提供的红光荧光膜。
对比例C3

表3第一芯片、第二芯片和第三芯片的发光波长
各光源的光谱测试：
将上述实施例C1至实施例C9和对比例C1至对比例C3提供的红光LED光源分别进行光谱测试。
测试结果为如图2至图13所示，其中，实施例C1至实施例C9中光源的光谱图如图2至图10所示，比例C1至对比例C3中光源的光谱图如图11至图13所示。
由图2至图10可知，本申请实施例C1至实施例C9提供的红光LED光源所产生的红光，在波峰前后较宽的波段内峰形平坦，该波段内红光的绝对光谱与红光的最大绝对光谱值相近(如该波段的光功率或绝对相对光谱值大于或等于最大光功率或最大绝对相对光谱值的80％)，理疗时，该波段的红光能产生理疗效果，该波段是有效波段，实施例C1至实施例C9提供的红光LED光源所产的红光理疗的有效波段宽，理疗效果好。
由图11至图13可知，对比例C1至对比例C3的红光LED光源所产生的红光，波峰前后的峰形陡峭，波峰窄且尖锐，随着波长的增大，红光的绝对光谱值或光功率迅速增大，绝对光谱值或光功率达到最大值后又迅速减小，红光的最大绝对光谱值或光功率与其他波长下的绝对光谱值或光功率存在较大差异，仅有波峰前后很窄的波段范围内的光谱值或光功率与最大绝对光谱值或光功率相近，理疗时，仅有波峰前后很窄的波段下的红光能够产生理疗效果，理疗效果不好。对比例C1至对比例C3提供的红光LED光源所产生的红光理疗的有效波段窄，理疗效果不佳。
