LED dimming sensor

Abstract

The invention relates to an LED dimming sensor which comprises a microprocessor module as well as a microwave collection module, an infrared collection module, an illuminance collection module, a bus communication module used for receiving a remote control command and a dimming module used for LED brightness adjustment, which are connected with the microprocessor module, wherein an optoelectronic isolation circuit is arranged between the microprocessor module and the dimming module. The dimming sensor can be compatible with a traditional human body sensing lamp to realize the dimming and the switching control of LED light sources widely applied at present and has the advantages of more reliable and stable detection effect, effective avoidance to interferences and good energy saving effect; meanwhile, the sensor also can be used as a node of a D_BUS control system and coordinates to work with other modules in the system through the bus communication circuit so as to form a complicated control system, make up the deficiency of single scene control of the traditional human body sensing lamp and achieve the effect of outputting any scene.

Description

technical field [0001] The invention relates to the field of intelligent lighting, in particular to an LED dimming sensor. Background technique [0002] Traditional infrared or microwave induction lamps have many problems such as being greatly affected by temperature, susceptible to interference from small animals and other environments, high false alarm rate, and poor sensitivity and stability. Therefore, Sanjian detection technology is proposed, using microwave, infrared and illumination technology, through the collection of environmental illumination value, far-infrared spectrum emitted by human body and Doppler frequency shift signal generated by human walking, intelligent analysis and quantitative calculation are carried out to accurately detect Recognize the movement of the human body and realize the stable control of the induction lamp. [0003] However, the existing Sanjian sensors generally have the problems of untargeted control, resulting in poor dimming effect a...

Problems solved by technology

[0003] However, the existing Sanjian sensors generally have untargeted control, resulting in poor dimming effect and unstable control.

For LED lights, the application of LED itself lies in its energy saving and stability. However, the existing LED dimming devices are susceptible to interference and have a high false alarm rate, resulting in poor energy saving effects.

Moreover, the existing dimming sensor has a single and fixed control scene, which can only realize the switch control of the light source, cannot configure the output scene, and cannot build a system to realize centralized control of the system
