Thus, such lighting devices are increasingly subject to requirements for glare and spot adjustment.

The size of the light spot is generally formed by matching an anti-dazzle cover and other optical components, and the optical components are often arranged in the market in the following two modes: (1) The fixed light spot is a common optical form, the optical system components are relatively fixed and are in an unadjustable state, and the glare effect can be optimized at the factory; however, as the components are fixed, the light spots cannot be optimally adjusted according to scene requirements, and the diversified requirements of users cannot be met; (2) The fixed glare structure usually needs to be combined with a standard optical piece to carry out luminous surface sinking design, and the protection angle is usually designed to be about 15 degrees; however, the user with high anti-dazzle requirements cannot be effectively compatible.

In addition, in the anti-dazzle structure, the lighting device on the market also adopts a structure of a fog-like diffusion cover and a honeycomb net.
