AI Technical Summary
The LED low beam spotlights of motorcycles and electric bicycles generally adopt a lens structure that receives the light source in a planar manner, resulting in low light energy utilization and a limited vertical light distribution range, making it difficult to meet the cutoff line requirements and affecting the driver's ability to identify nearby obstacles.
A lens module is used, including a first lens and a light-shielding component. The receiving surface of the first lens is inclined and bent inward from bottom to top. Combined with a second lens and a positioning protrusion, a semi-concave lens structure is formed to enhance the focusing effect and utilization of light, and to prevent light leakage through the light-shielding component.
It significantly improves light energy utilization, expands the vertical light distribution range, provides a wider horizontal and vertical light distribution, enhances the driver's ability to identify nearby obstacles, and achieves a thinner and lighter lens module design and efficient heat dissipation, thereby improving the stability and lighting effect of the spotlight.
