According to structural design, beam angle characteristics, and application lamp types, lighting lenses can be divided into three mainstream categories: single convex lighting lenses, concave floodlight lenses, and integrated multi-lens arrays, each with exclusive application scenarios in architectural lighting, commercial lighting, and industrial lighting. Classified by functional attributes, they can also be divided into spotlight lenses for directional illumination and floodlight lenses for large-area uniform lighting, covering almost all lamp types on the market.

Spotlight lighting lenses are the most widely used type in commercial lamps. Mostly designed with convex curved structures, they can converge light sources into narrow and precise beam angles ranging from 10 degrees to 60 degrees. This type of lens is mainly applied to track lights, downlights, spotlights, and display cabinet lamps used in shopping malls, clothing stores, and exhibition halls. It can accurately focus light on goods, artworks, and key decoration areas, highlighting the layering and three-dimensional sense of lighting, and avoiding light scattering to ensure centralized and efficient lighting effects.

Floodlight lighting lenses adopt concave and ultra-flat optical designs, which diffuse the concentrated light source evenly to form a wide-range illumination area with a beam angle of 90 degrees to 180 degrees. They are widely installed in outdoor floodlights, street lamps, factory high bay lights, and indoor panel lights. In industrial workshops, urban road lighting, and large-space office environments, these lenses can eliminate local dark areas, realize seamless and uniform large-area lighting, and effectively reduce visual fatigue caused by uneven light brightness.

In addition, integrated lens arrays are specially developed for high-density LED lamp groups. This integrated design combines multiple small optical lenses into one integral component, which is convenient for batch installation and assembly of lamps. It is commonly used in LED ceiling lights, linear lights, and stage lighting equipment. With the continuous refinement of lighting market demand, customized special-shaped lenses for underwater lamps, landscape lamps, and stage effect lamps have also emerged. Different types of lighting lenses support the differentiated design of various lamps, helping the lighting industry achieve precise, energy-saving, and high-quality light output in diverse application environments.
