AI Technical Summary
Technical Problem
Existing industrial and mining lighting fixtures lack a systematic optical layout design, resulting in scattered and disordered light, low light utilization, and densely arranged LED beads leading to high temperature, short lifespan, and glare problems.
Method used
It adopts a coaxial optical assembly architecture, arranges LED beads in concentric rings, and combines a central focusing structure, a side light control structure and an inner wall light path recovery structure to form an integrated optical system, which presets the light path trajectory and constrains the propagation of light.
Benefits of technology
It achieves orderly light propagation, improves light utilization, reduces glare, extends lamp life, and enhances illuminance and luminous efficacy.

Abstract
The scheme discloses a high-light-efficiency energy-saving coaxial light path constraint concentric ring light distribution industrial and mining lighting lamp and a light distribution structure forming method, and belongs to the field of industrial and mining lighting optical structures. The lamp is provided with an integrated coaxial optical assembly structure, and a split type optical component assembly structure is abandoned. A light source plate is arranged with concentric ring arranged light emitting elements, the arrangement center is coaxially aligned with the light emitting center, the center area is hollow without lamp beads, a single ring lamp bead reserved light path channel is arranged, and a reflective ring part with four corner positioning is arranged on the inner side. The lamp is provided with built-in central axis light collecting structure, lateral light control structure and light path recycling structure, and the three types of structures are coaxially arranged. The application adopts optical logic of controlling light first and then emitting light, relies on five optical linkages to form a closed loop light path control, solves the hardware defects of traditional industrial and mining lamps, such as glare, light path disorder, mutual interference of lamp beads, stray light interference of main light path and low light efficiency, and the like, and solves the problem of forced correction of light path by relying on lenses due to disordered arrangement of the lamps. The idle light can be recycled and reused, the lamp bead arrangement does not have interlayer interference, the material is less, the light emission direction is concentrated, the overall illuminance and light efficiency are synchronously improved, the optical integration is high, and the lamp can be adapted to multiple power and multiple working condition lighting scenes.
