Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to a polarized optical light strip and a lighting device. Background Art

[0002] Currently, most lighting products on the market use a design that combines a light source with a fixed-angle lens. Although this design can meet basic lighting needs to a certain extent, it has significant limitations. First, the product's luminous angle is strictly limited by the design angle of the lens, resulting in problems such as large product size and large luminous angle, making it difficult to achieve flexible light direction adjustment. Secondly, in some scenarios where precise control of light distribution is required, when the light strip is required to emit light at a specific angle, small-angle polarization becomes particularly important. Traditional lenses often find it difficult to achieve the effect of emitting light at a small angle or in a specific direction by themselves, and require post-processing, which leads to problems such as uneven light distribution or light spot distortion.
