控制器102用于调整光源模组104所发出照射光的光色和光强，散热器102用于将光源模组104发光期间的热量散出，光学元件105包括透镜、灯罩等多种类型，用于调整光源模组104所发出照射光的照射方向和角度。
控制器102、散热器103以及光学元件105的结构和工作原理为本领域普通技术人员所熟知的技术，在此不做扩展。
光源模组102包括蓝光发生部、红光发生部和黄绿光发生部，三者分别被配置为发出蓝光、红光和黄绿光。
蓝光发生部可以采用被配置为发出蓝色光的发光单元，也可以采用发出其他颜色光的发光单元与一个蓝色的荧光体配合以发出所需的蓝色光。
红光发生部可以采用被配置为发出红色光的发光单元，也可以采用发出其他颜色光的发光单元与一个红色的荧光体配合以发出所需的红色光。
黄绿光发生部可以采用被配置为发出黄绿色光的发光单元，也可以采用发出其他颜色光的发光单元与一个黄绿色的荧光体配合以发出所需的黄绿色光。
在本发明的实施例中，蓝光发生部、红光发生部和黄绿光发生部 可以各自具有单独的发光单元，也可以共用一个发光单元，例如可以仅有蓝光发生部包括发光单元，而红光发生部和黄绿光发生部可以仅具有荧光体，红光发生部和黄绿光发生部的荧光体分别将蓝光发生部所发出蓝光经过波长转换调整为对应的红光和黄绿光。
当然，也可以仅有红光发生部包括发光单元，而蓝光发生部和黄绿光发生部仅具有荧光体，蓝光发生部和黄绿光发生部的荧光体分别将红光发生部所发出红光经过波长转换调整为对应的蓝光和黄绿光。
发光单元可选为LED元件，也可以为其他元件类型，在此不做赘述。
荧光体可以选用铝酸盐荧光体、硅酸盐荧光体、氮化物荧光体、硫化物荧光体等。
值得注意的是：黄绿光发生部可以包含一种荧光体激发产生黄绿光，也可以采用两种以上荧光体组合，例如可激发黄光的荧光体和可激发绿光的荧光体组合，甚至可以由多种峰值波长的荧光体组合而成，当由多种荧光体组合时，这些荧光体并不限定在一个元器件中，例如可以是两个白光LED元件中的不同的黄绿光荧光体，由他们产生的光谱叠加获得我们需要的515-560nm间的光谱强度。这种荧光体的组合并不局限于黄绿光发生部，当蓝光发生部、红光发生部包含荧光体时，也可以采用多种成分的荧光体，并且这些荧光体可以分布在不同的器件中。另外，这里的黄绿光荧光体优选的采用宽带荧光体，宽带荧光体是业内通用的一个概念，是指激发光半峰全宽(FWHM)较宽的荧光粉，这种较宽是相对于氧化钇铕(红粉)、量子点荧光体等窄带荧光材料而言的，在本发明中的宽带荧光体其半峰全宽优选的大于30nm，更优选的大于40nm，特别优选的大于50nm，格外优选的大于80nm。另外，红光荧光体也可以采用宽带荧光体，应为红光波段和绿光波段相邻，红光发生部也采用宽带荧光体之后会在绿光波段也有一定的能量，这样和黄绿光发生部的发光叠加后也可以在一定程度上增加该波段的光强，使之符合本发明需要的光谱。需要说明的是，在这里红光发生部及黄绿光发生部仅是为了说明本发明而采用的一种描述，就如红光荧光体的发射带宽较宽的必定有部分能量在黄绿光区域，这个时候我们可以理解为红光荧光体部分实现了红光发生部的功能，部分为黄绿光发射作贡献，即黄绿光发生部是由黄绿光荧光体和红光荧光体组成的。
以下结合照明装置101的结构，描述照明装置101所发出照射光的组成。
图2为照明装置101所发出照射光和现有技术中照射光的光谱比对图。L1为本发明的照明装置101在色温3000K的光谱分布图，虚线L2为现有照明装置在3000K的光谱分布图，其主峰为波长在450nm的蓝光。在此我们把主峰能量设定为数值1，而其他点的能量在图中表示为和主峰能量的相对比值，其红光峰值较L2更靠近长波，峰值强度也更高，在560～590nm处光谱强度低于L2光谱，通过大量的试验证明：在L1光照环境下皮肤白皙度、红润度和健康度明显优于L2光照环境下。
色温3000K与当前家居场所的色温范围基本接近，本发明所提供的照明装置101所发出照射光使得人们在家居场所的皮肤观感大大提升。
在本发明的实施例中，蓝光的峰值波长在440～460nm范围内。
红光的峰值波长在600～640nm范围内，并且蓝光的峰值强度在所述红光的峰值强度的65％～100％。在蓝光的基础上增加红光，可以使得皮肤的观感更红润，符合中国人的审美需求，也使得皮肤的健康度大大提升。通过设定红光的峰值波长以及其峰值强度，而使得皮肤显得过红而造成观感异样。
在本发明的实施例中，蓝光的峰值强度在所述红光的峰值强度的范围的下限值还可以是70％，或更进一步的80％；蓝光的峰值强度在所述红光的峰值强度的范围的上限值还可以是95％。通过将这个范围内的上限值和下限值做组合，得到例如70％～95％或80％～95％的范围，这些范围内的红光均可以实现本发明的发明目的。
所述黄绿光的峰值波长在525～565nm范围内，黄绿光的峰值强度为所述红光的峰值强度的35％～65％。在蓝光和红光的基础上增加黄绿光，是利用黄绿光能够调和光色的能力，使得皮肤的观感更真实，保证皮肤的观感的真实性。
在本发明的实施例中，黄绿光的峰值强度在所述红光的峰值强度的范围的下限值还可以是40％；红光的峰值强度在红光的峰值强度的范围的上限值还可以是60％。通过将这个范围内的上限值和下限值做组合，得到例如40％～60％的范围，这些范围内的黄绿光均可以实现本发明 的发明目的。
在所述光源模组没有其他光线时，所述光源模组所发出照射光符合CIE1931色坐标系中的如下条件：横坐标X在0.4015～0.4315范围内；所述纵坐标Y在0.347～0.377范围内。
色坐标反映的是被测量物体在色品图中的位置，是利用数学方法来表示颜色的基本参数，其横坐标X和纵坐标Y可以通过如下方式获得：在获得光谱P(λ)后，将光谱P(λ)与三刺激函数x(λ)、y(λ)、z(λ)，分别对应波长相乘后累加，得出三刺激值，x、y、z。再将三刺激值x、y、z做换算则可以得到色坐标的横坐标X＝X/(x+y+z)、纵坐标Y＝Y/(x+y+z)。为本领域普通技术人员所熟知的技术，在此不做扩展。
值得注意的是，确定光源模组的照射光符合CIE1931色坐标系中上述条件时，光源模组所在环境没有任何光线存在，从而避免了由于存在其他光线掺杂在光源模组所发出照射光内，使得光源模组所发出照射光污染，而无法精准确定光源模组所发出照射光在色品图内位置。
在本发明实施例中，可以将光源模组内置于一个与外界光线隔离的暗房或黑匣子内，使得光源模组所在环境无其他光线存在，进而确定光源模组所发出照射光符合CIE1931色坐标系中上述条件。
在本发明的实施例中，色坐标系中的条件可调整为：横坐标X在0.4065～0.4265范围内；所述纵坐标Y在0.352～0.372范围内。
在本发明的实施例中，色坐标系中的条件还可调整为：横坐标X在0.4115～0.4225范围内；所述纵坐标Y在0.357～0.367范围内。
本发明所提供的照明装置主要应用于照明，并在光照环境下提升皮肤的观感。照射光需要的是接近白光的光色，并且光色落在上面划定的CIE1931色坐标范围内，才可以实现常规照明能力的同时，提升皮肤的白皙度、红润度、健康度以及自然性和生动性。
