Intelligent fine dimming dental chair oral lamp and dimming method

Abstract

The invention provides an intelligent fine dimming dental chair oral lamp and a dimming method, and belongs to the field of lighting control. The dental chair oral lamp comprises a main adjusting module, a micro-adjusting module, a micro-controller module, a light source driving module, a lighting unit and a power source module, wherein the main adjusting module is connected with the micro-controller module, and is used for initial dimming of a lighting unit; the micro-adjusting module is connected with the micro-controller module, and is used for fine adjustment of the brightness of the lighting unit; the micro-controller module is used for receiving input signals of the main adjusting module and the micro-adjusting module and used for outputting a control signal to the light source driving module; the light source driving module is connected with the micro-controller module, and is used for receiving the control signal of the micro-controller module and used for brightness adjustment of the lighting unit; the lighting unit is connected with the light source driving module, and is used for receiving an adjusting signal input by the light source driving module and used for brightness updating; the power source module is connected with the main adjusting module, the micro-adjusting module, the micro-controller module and the light source driving module respectively, and is used for providing the power source. The dental chair oral lamp and the dimming method have the benefits that by rapidly combining initial dimming and fine dimming, dimming efficiency and dimming accuracy are improved, and the oral lamp is more convenient to operate.

Description

technical field [0001] The invention belongs to the technical field of lighting control, and in particular relates to an intelligent fine-tuning dental chair oral light and a dimming method. Background technique [0002] Dental light is a commonly used auxiliary equipment in dental treatment. It is used to illuminate the patient's oral area. In order for the doctor to clearly observe the patient's teeth and make accurate judgments, it is necessary to provide sufficient illumination in the patient's oral area. [0003] With the wide application of LEDs, some LED lighting applications have appeared on the market, and some oral lamps with LEDs as light sources have also appeared at home and abroad. The existing LED oral lamps can be divided into two types of dimming, infrared dimming and manual dimming, and both methods have their own defects. For example, infrared control dimming is mostly used to turn on and off the oral light. It can only adjust the presence or absence of th...

[0003] With the wide application of LEDs, some LED lighting applications have appeared on the market, and some oral lamps with LEDs as light sources have also appeared at home and abroad. The existing LED oral lamps can be divided into two types of dimming, infrared dimming and manual dimming, and both methods have their own defects. For example, infrared control dimming is mostly used to turn on and off the oral light. It can only adjust the presence or absence of the light, but not the brightness. To adjust the intensity of brightness, you need to configure an independent remote control to realize it. In this case, you need two sets of independent lighting control systems.

Not only is the operation not convenient enough, but also the dimming accuracy cannot be guaranteed. Although the manual dimming of the independent remote control can roughly adjust the brightness, when the doctor observes the patient's mouth, because the mouth is narrow and the illumination is high, so It is necessary to manually adjust the light source to see the specific situation of the oral cavity, resulting in one hand operating the remote control, which affects the effect and efficiency of medical treatment, and the operation is also cumbersome, which is very inconvenient for the treatment process and cannot be controlled by PWM stepless dimming , causing serious inconvenience to patients or doctors during use
