Description
Technical Field
The utility model relates to the technical field of curved surface scattering, in particular to a curved surface scattering code reading lighting unit.
Background
The scattering is the phenomenon that when the surface curvature of an object irradiated by the projected wave is large or even unsmooth, the secondary radiation wave is in diffusion distribution in an angular domain according to a certain rule. When molecules or atoms are close to each other, the strong repulsive force between the two parties forces them to move away from the original direction of motion before they touch, which is commonly referred to as "scattering". Scattering refers to the phenomenon of light rays being emitted all around due to the inhomogeneity of the propagation medium.
The light source diffusion piece in the prior art on the market is of a flat plate structure, and cannot gather diffused light sources towards the lens direction and exert the function of an illumination light source to the maximum extent, so that the utility model provides a curved surface scattering code reading illumination unit.
SUMMERY OF THE UTILITY MODEL
The utility model provides a curved surface scattering code reading illumination unit, which is characterized in that through the design of an inward concave curved surface diffusion structure, after a light source passes through a part, the light source is gathered towards the middle of a lens while being uniformly diffused outwards, so that the illumination effect of the light source is greatly improved, and the reading effect of code scanning equipment is greatly improved.
In order to solve the technical problems, the utility model adopts the technical scheme that: the utility model provides a code lighting unit is read in curved surface scattering, includes takes illuminating source reading equipment body and light source scattering spare, take the illuminating source to install the light source scattering spare that is used for the spotlight on the illuminating source reading equipment body, the light source scattering spare is indent formula curved surface structure, take illuminating source reading equipment body internally mounted have because the LED light source board of installation LED lamp pearl, the LED lamp pearl is in evenly arrange on the LED light source board.
Furthermore, a lens module used for reading bar codes is further installed inside the reading equipment body with the lighting source, and a through hole matched with the lens module is formed in the light source scattering piece.
Furthermore, the reading equipment body with the illumination light source is connected with four corners of the light source scattering piece through screws.
Further, the light source scattering piece is made by mixing a PC material and a diffusion agent material.
Compared with the prior art, the utility model has the following beneficial effects:
1. according to the utility model, through the design of the concave curved surface diffusion structure, after the light source passes through the part, the light source is uniformly diffused outwards and gathered towards the middle of the lens, so that the lighting effect of the light source is greatly improved, and the reading effect of the code scanning device is greatly improved.
