As shown in fig. 1 and 2, the LED light source 1 is located in a groove of the condenser lens 5. The condenser lens 5 and the LED light source 1 are positioned on the inner side of the micro-curved array reflector 2. The micro-curved array reflectors 2 are 2 groups, and each group of micro-curved array reflectors 2 is provided with 5 concave curved surfaces. 1 LED light source 1 and 1 condensing lens 5 are a set of LED light source subassembly, and every group LED light source subassembly is located the inboard of an indent curved surface, and the installation center of LED light source 1 and condensing lens 5 is located the focus position of the indent curved surface of little curved surface array speculum 2. The prism 3 is disposed along the propagation direction of the outgoing light of the micro-curved array mirror 2 and spaced apart from the micro-curved array mirror 2 by a predetermined distance.
After being condensed by the condenser lens 5, the light of each LED light source 1 is incident on the concave curved surface for reflection, and the mode can effectively enhance the brightness of the light and improve the utilization rate of the light energy. Each LED light source 1 adopts side-in type light emission relative to the concave curved surface of the corresponding micro-curved surface array reflector 2. Then, the light reflected by the micro-curved array reflector 2 is turned by a special-shaped prism 3, and the light is emitted from the light outlet of the lamp.
