一种滤光镜片、具有该滤光镜片的LED灯及照明系统
摘要：
一种滤光镜片、具有该滤光镜片的LED灯及照明系统，所述照明系统包括一个具有滤光镜片的LED灯，以及一个被照射面。所述具有滤光镜片的LED灯包括一个发光模块，一个准直透镜，以及一个滤光镜片，所述滤光镜片包括一个入光面，以及一个设置在所述入光面相反侧的出光面，所述入光面包括多条首尾相连依次排列的异形槽。由于所述照明系统使用所述具有滤光镜片的LED灯，且该具有滤光镜片的LED灯的滤光镜片包括上述的异形槽，以及通过设置该具有滤光镜片的LED灯与被照射面之间的位置关系，使得射向离LED灯较远的被照射面的一侧的光相对于射向离LED灯较近的被照射面的一侧的光可以弥补由于到达离LED灯较远处而导致的更多的衰减，从而可以使得离LED灯较近处与离LED灯较远处有基本相同的照度。
摘要（英）：

The invention discloses a filter lens, an LED lamp with the filter lens and a lighting system. The lighting system comprises the LED lamp with the filter lens, and an irradiated face. The LED lamp with the filter lens comprises a light emitting module, a collimation lens and the filter lens. The filter lens comprises an incidence face and a light emitting face arranged on the opposite side of the incidence face. The incidence face comprises a plurality of special-shaped grooves which are connected in an end-to-end manner and sequentially arranged. Due to the fact that the lighting system uses the LED lamp with the filter lens, the filter lens of the LED lamp with the filter lens comprises the above special-shaped grooves and the position relation between the LED lamp with the filter lens and the irradiated face is set, more attenuation can be offset by the light irradiating to the side, far away from the LED lamp, of the irradiated face relative to the light irradiating to the side, close to the LED lamp, of the irradiated face, and accordingly the position close to the LED lamp and the position far away from the LED lamp have basically the same illuminance, wherein more attenuation of light is caused by the fact that the light arrives at the position far away from the LED lamp.
