  • Light bar structure
    Patent number: 10941919
    Abstract: The present disclosure relates to a light bar structure, comprising: a circuit substrate, a spot light source matrix, and a light guide film. The light guide film comprises a plurality of strip-shaped micro lenses on the surface opposite to the spot light source matrix, and these strip-shaped micro lenses further comprise a plurality of gratings on the surfaces thereof. With the refraction and diffraction of the light guiding film, the diffusion angle of the light emitted from the spot light source matrix can be increased in one dimension, and the light bar structure can exhibit a uniform one-dimensional pattern.
