Abstract

The embodiment of the present invention discloses a control system for an ultraviolet light-emitting diode light source, including: an ultraviolet light-emitting diode UVLED light source module, a current collection module, a set current output module, a comparison module, and a pulse width modulation PWM module; the UVLED light source module is used to emit Ultraviolet light; the current acquisition module is electrically connected to the UVLED light source module for collecting the operating current of the UVLED light source; the comparison module is electrically connected to the set current output module and the current acquisition module respectively, and is used to output the set current and the operating current to the comparison module; the comparison module is used to generate a control signal according to the set current and the working current; the comparison module is electrically connected to the PWM module, and is used to send the control signal to the PWM module; the PWM module is used to generate a PWM drive signal according to the control signal, and pass The PWM driving signal drives the UVLED light source. The technical solution provided by the embodiments of the present invention can solve the problem that the light decay period of the UVLED light source is relatively short due to the control method of the existing UVLED light source.

Description

technical field [0001] Embodiments of the present invention relate to the field of organic light emitting diodes, and in particular to a control system for an ultraviolet light emitting diode light source. Background technique [0002] Ultraviolet Light Emitting Diode (UVLED) is a kind of LED lamp, which emits single-wavelength invisible light, and the wavelength is generally below 400nm. Set the UVLED light source into different shapes and different irradiance spots to meet the production needs of edge banding, printing and other fields. UVLED light source has a long life, stable performance, and has a bactericidal effect. It has a wide range of applications in various fields such as printing, industrial curing, anti-counterfeiting, disinfection, and medical treatment. [0003] Most of the traditional driving methods for UVLED light sources are constant voltage control methods. With the increase of the working time of UVLED light sources, the junction temperature of UVLED ...
