所述第一光源模组100发出波长在第一光谱范围的第一光线，在本实施例中，所述第一光谱范围的光为红光，所述第一光源模组100包括多个红光LED光源101和对应设置在所述红光LED光源101上的第一透镜102，所述第一光线为红光，所述第一透镜102用于对所述红光进行准直。
所述第二光源模组200发出复色光，所述复色光包括波长在第一光谱范围的第五光线、波长在第二光谱范围的第二光线和波长在第三光谱范围的第三光线，所述第二光谱范围的光为蓝光，所述第三光谱范围的光为绿光。具体实施例中，所述第二光源模组200包括多个蓝光LED光源201和波长转换装置（图未示），所述蓝光LED光源201照射在所述波长转换装置上以激发出具有一定光谱范围的复色绿光。具体地，所述复色光的光谱范围在400-700nm之间，其中主要包括波长范围在500-560nm的绿光，即所述第三光线，以及包括少量蓝光和红光，即所述第二光线和第五光线。所述第二光源模组200还包括多个第二透镜202，且对应设置在所述蓝光LED光源201上，以对所述蓝光LED光源201发出的光线进行准直。
所述第三光源模组300发出波长在第二光谱范围的第四光线，所述第三光源模组300包括多个蓝光LED光源301和对应设置在所述蓝光LED光源301上的第三透镜302。所述第四光线为蓝光，所述第三透镜302用于对所述第四光线进行准直。
所述第一滤光片400为蓝光滤光片，反射蓝光及透射红光和绿光，所述第二滤光片500为红光滤光片，反射红光及透射蓝光和绿光。
如图1所示，所述聚光透镜组600设置在所述第二光源模组200和所述光源装置出光口之间，且面向所述第二光源模组200设置。所述第一光源模组100发出的红光经由第二滤光片500反射后，再经聚光透镜组600由光源装置出光口发出，如图2所示，所述第三光源模组300发出的蓝光经由第一滤光片400反射后，再经聚光透镜组600由光源装置出光口发出。
请参阅图3，所述第二光源模组200采用蓝光芯片提升亮度，发出的复色光在通过第一滤光片400和第二滤光片500后，截掉蓝光部分和红光部分，得到绿光，所述绿光再经聚光透镜组600由光源装置出光口发出。也就是，所述复色光在通过第一滤光片400时会反射蓝光部分，通过第二滤光片500时会反射红光部分，反射的红光会反射到蓝光LED光源301上，反射的蓝光则会反射到红光LED光源101，在现有技术没有在第一光源模组100和第三光源模组300分别设置隔离装置时，反射的红光造成蓝光LED光源301光衰，反射的蓝光则会造成红光LED光源101光衰。由于蓝光波长短，能量大，所以蓝光照射在红光LED光源101上会导致红光衰减更为严重，因此图3以第一滤光片400对蓝光反射的光路为示例说明，而简化了第二滤光片500对红光反射的光路。
本实用新型在第一光源模组100设置了第一隔离装置（图未示），具体可以在第一透镜102上镀蓝光反射膜（图未示），如图3所示，所述复色光经第一滤光片400反射的蓝光11、12、13，照射在红光LED光源101上，由于第一透镜102上镀有蓝光反射膜，这部分蓝光11、12、13又反射出来，避免了反射的蓝光导致红光衰减的问题。
同样道理，本实用新型在第三光源模组300设置了红光反射装置（图未示），具体可以在第三透镜302上镀红光反射膜（图未示），所述复色光经第二滤光片500反射的红光照射在蓝光LED光源301上，经由所述红光反射膜又反射出来，避免了反射的红光导致蓝光衰减的问题。
在本实施例中，所述第二光源模组200还设有吸收反射回来的蓝光和红光的吸光材料（图未示），具体可设置在第二光源模组200的多个蓝光LED光源201之间。而部分返回的蓝光会照射在蓝光LED光源201上，由于返回的蓝光波长比蓝光LED光源201的激发蓝光的波长要长，因此返回到蓝光LED光源201上的蓝光会再次激发波长转换装置从而产生部分绿光，而其余返回的蓝光则被吸光材料所吸收。
以上仅为本实用新型的实施方式，并非因此限制本实用新型的专利范围，凡是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本实用新型的专利保护范围。
