UVLED light condensation method

Abstract

The invention discloses a UVLED light condensation method. The UVLED light condensation method comprises the following steps that light beams are subjected to initial energy concentration, and specifically, linear energy of UVLED lamp beads is controlled by adjusting the arrangement mode of the UVLED lamp beads which are subjected to one time of light distribution and have certain irradiation angles to achieve initial light beam energy concentration; light beams are shaped, specifically, the light beams subjected to initial concentration are shaped through a shaping lens, and then shaped light beams are output; and the light beams are further focused, and specifically, the shaped light beams are subjected to linear focusing through a condenser lens. The UVLED light condensation method is applied for light source design, in particular to light beam condensation design so that power consumption can be greatly reduced, the working life of equipment is long, heat productivity of a drying device can be reduced, no ozone is generated, instantaneous lamp turning-on and lamp turning-off can be achieved, energy source consumption can be reduced by 70-80%, the environment is protected, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of optical engineering, in particular to a method for converging UVLED light. Background technique [0002] At present, in the fields of UV curing (printing, PCB electronics, quick-drying glue, electronic conformal paint, etc.), the ultraviolet light sources used are generally high-pressure mercury lamps and metal halide lamps. Due to the large-scale lamps and power supply devices, the power consumption is large and Problems such as high heat generation and ozone generation during use make UV curing a high energy consumption and high pollution process. [0003] Since the divergence angle of UVLED lamp beads is relatively large, the distance irradiated by UVLED ultraviolet light has a great influence on the curing effect. This requires secondary light distribution of UV LEDs to gather UV energy for long-distance irradiation of targets. Contents of the invention [0004] The purpose of the present inventio...
