AI Technical Summary
In the existing technology, the lighting module is expensive to realize the function of signal lights lighting up together, and requires additional signal light sources and lenses, which increases the number of parts and complicates assembly.
By setting rotatable optical elements in the lighting module, the switching between signal light and lighting functions can be achieved by switching the positions of the lens module and the optical elements. This reduces the use of independent signal light sources and lenses. Furthermore, by combining integrated lenses and separate lenses, the optical path design is optimized to reduce cost and size.
It enables the simultaneous lighting of signal lights without adding any components to existing lighting modules, reducing production and labor costs while improving luminous efficiency and structural compactness, and adapting to various lighting scenarios.
