New description: [New technical field] This creation is about the LED lens 'especially the kind of asymmetrical leD lens used for street lighting' and providing an offset illumination area. [Prior Art] In recent years, due to the increasing global warming problem, environmentally-friendly products with energy-saving and carbon-reducing effects have received much attention. In terms of lighting, the most potential for development of Light Emitting Diodes (LEDs) It has the advantages of high brightness, power saving, long service life, etc., and has gradually replaced traditional light bulbs, and is widely used in various lighting devices. In the prior art, the LED applied to the street lamp is provided with a led lens on the light-emitting side cover, so that the light emitted by the LED can be incident on the LED lens to generate offset refracting, and the offset refracted light is emitted from the surface of the LED lens. Offset refraction is further generated, thereby adjusting the light emitted by the LED to be projected in a particular direction. However, when the street lamp system is disposed on both sides of the road, the prior art LED lens can provide the offset refraction effect of the j_ED light, which cannot effectively illuminate the light on the road, and the light is mostly irradiated under the street lamp setting. The road lighting effect is not good, so it needs to be improved.
