Description

Combined type grading module Technical Field The application relates to the technical field of optical illumination, in particular to a composite light distribution module. Background Along with the development of social economy, the demand of the advertising light boxes is increased, and meanwhile, the demand of the advertising light boxes is also increased. The traditional light distribution module has the problems of single light distribution mode, low light efficiency utilization rate and the like, and is difficult to meet the diversified scene demands such as gradual thinning development of a lamp box. Part of the prior art is improved, but the structure is complex, the cost is high, the adjustment flexibility is insufficient, the application thickness of the advertising lamp box on the market is basically more than 6CM thick, and the problems that the product application cost is high, the occupied space is large, the light box is densely distributed with hemp and the like are generally existed, and the light guide plate scheme (the light guide plate is too heavy) is realized by the reflection of the television backlight scheme (the light utilization rate is very low and the reflecting surface has higher requirement). Disclosure of Invention The application aims to provide a composite light distribution module which is used for solving the problems of single light distribution mode, low light efficiency utilization rate, complex structure, high cost, insufficient adjustment flexibility, high product application cost, large occupied space and low light utilization rate in the prior art. The application provides a composite light distribution module, which comprises a substrate, a lens, lamp beads, wires and a shell, wherein the substrate is provided with a plurality of light guide plates; the upper surface of the substrate is provided with a lamp bead and a lens, the lamp bead is positioned in the lens, the substrate is provided with a silk screen layer, and the silk screen layer surrounds the joint of the lens and the substrate; the wires are respectively connected to two ends of the substrate; The shell is provided with an accommodating space and provided with a first opening and a second opening, the substrate is arranged in the accommodating space, the protruding part of the lens is arranged at the first opening, and the wire rod penetrates through the second opening. The lens is circular with the junction of base plate, the lamp pearl is located circular centre of a circle department, encircle in circular region is provided with the silk screen printing layer. The silk screen printing layer is a black silk screen printing layer. The thickness of the silk screen layer ranges from 10 mu m to 25 mu m, and the thickness of the silk screen layer gradually becomes thicker from the edge of the lens to the outer side. As described above, the composite light distribution module has the following beneficial effects: the light efficiency utilization rate is high, the structure is simple, the cost is low, the adjustment flexibility is good, the occupied space is small, and the light utilization rate is high.
