实施例7:本实施例与实施例1的不同之处在于，如图16、17所示，由上至下所述的反光杯是由2段杯体连接组成，反光杯的母线为折线，每段杯体又是由多个曲面板17沿圆周方向依次连接组成，曲面板17的横截面、纵截面均为弧形，且每块曲面板17都是由外部向反光杯中心处弯曲。  Example 7: This Example is different from Example 1 in that, as shown, from top to bottom of the reflector cup 2 is connected to the cup body segments 16, 17, bus reflector cup polylines, in turn, a plurality of curved plates 17 in the circumferential direction of each cup are sequentially connected to form the cross-section of the curved plate 17, a longitudinal section are curved, and each curved plate 17 are from outside to the center of the reflective cup bend.  这样的方式，适合于反光杯外面的LED光源分布成几个区块，即除在反光杯外沿杯口圆周上均匀分布的情况，每个LED光源区块与反光杯的曲面板对应，可以得到在空间分布更均匀的配光或其他的配光。  In this manner, the reflective cup is adapted to the outer profile of the LED light source into several blocks, i.e., except where the outer edge of the reflector cup cup uniformly distributed circumferentially, each LED light source block and the reflector cup curved plate correspondence can be obtained with a more uniform light distribution or light distribution in the other space.  实施例8:本实施例与实施例1的不同之处在于，如图18、19所示，由上至下所述的反光杯是由2段杯体连接组成，反光杯的母线为折线，每段杯体又是由多个梯形板18沿圆周方向依次连接组成，梯形板18为平面板。  Example 8: This Example is different from Example 1 in that, as shown, from top to bottom of the reflector cup 2 is composed of segments 18, 19 connected to the cup, the bus reflector cup polylines, in turn, a plurality of trapezoidal-shaped plate 18 in the circumferential direction of each cup are sequentially connected to form, trapezoidal-shaped plate 18 to the flat plate. 同样，这样的方式，也适合于反光杯外面的LED光源9分布成几个区块，即除在反光杯外沿杯口圆周上均匀分布的情况，每个LED光源区块与反光杯的梯形板对应，可以得到在空间分布更均匀的配光或其他的配光。 Also, this way, also suitable for the outer reflector cup LED light source 9 distributed into several blocks, i.e., except where the outer edge of the reflector cup cup uniformly distributed circumferentially, each LED light source block and the trapezoidal reflective cup the corresponding plate can be obtained with a more uniform light distribution or light distribution in the other space.  本发明优选实施例只是用于帮助阐述本发明。  Example embodiments of the present invention is preferably only used to help
