Intelligent light source control device capable of realizing stepless dimming

Abstract

The invention provides an intelligent light source control device capable of realizing stepless dimming which is mainly used for the light source control of a dizziness and nystagmus data acquisition system. The intelligent light source control device comprises a power supply system, an infrared light source, a visible light source, a photosensitive sensor, a light source controller and an SOC (System On Chip); the light source controller comprises a CPU (Central Processing Unit), an I2C bus controller, a serial bus controller, a UIOC (Universal Input / Output Controller), a visible light source PWM (Pulse Width Modulation) module, an infrared source PWM module, an analog / digital converter, a register list and an encryption module, wherein the CPU is connected with all modules respectively, a register is respectively connected with the encryption module, the visible light source PWM module, the infrared source PWM module and the analog / digital converter. The light source controller is available to the stepless dimming control of the visible light source and infrared light source of an LED (Light Emitting Diode) and the infrared light source can be controlled to emit uniform light to strongly irradiate the veins of irises of eyeballs, so as to display clear pupils of the eyeballs.

Description

technical field [0001] The invention relates to a light source control device, in particular to an intelligent light source control device capable of stepless dimming, which is mainly used for light source control of a vertigo and nystagmus data acquisition system. Background technique [0002] Vertigo is a common medical condition characterized by temporary dazzle (a perceived rotational movement, or a general sense of imbalance) and involuntary nystagmus of the eyeballs. Therefore, for nystagmus data collection, it is necessary to take video images of the eyeball, and the light source is required to illuminate the texture of the iris of the eyeball well, so as to capture a clear eyeball pupil image and obtain accurate nystagmus data; When the eyeball is photographed, it needs a comfortable brightness environment for the eyeball. At present, in the field of nystagmus data acquisition technology, there is no dedicated intelligent light source control device that can meet th...
