Embodiment Construction

[0025] In the prior art, the interaction between the MCU and the time base generator is usually used to generate different timing moments, and at different timing moments corresponding to PWM waves with different duty ratios, high and low level changes are generated, thereby generating PWM waves with different duty ratios. When the duty cycle of the PWM wave is constant, the number of interactions between the MCU and the time base generator is less, and only the initialization configuration needs to be completed. However, in the field of scene lighting, when the scene is switched, the duty cycle of the PWM wave is dynamically adjusted in real time according to the user's experience. At this time, the MCU needs to dynamically provide different dimming curves, and frequently communicate with the time base generator Interactively adjust the duty cycle of the PWM wave dynamically, which requires high computing performance of the MCU.

Abstract

The invention relates to an intelligent lighting control system, an intelligent lighting control method and an intelligent lighting system. The intelligent lighting control system includes a main controller, a PWM data buffer controller and a time base generator; the main controller is suitable for receiving a dimming instruction inputted by a user, generating corresponding target pulse width adjustment parameters according to the dimming instruction, sending the target pulse width adjustment parameters to the PWM data buffer controller, and sending a PWM wave generation instruction to the PWMdata buffer controller; the PWM data buffer controller is suitable for storing the target pulse width adjustment parameters, and controlling the time base generator to generate PWM waves corresponding to the target pulse width adjustment parameters when receiving the PWM wave generation instruction; and the time base generator is suitable for generating the PWM waves corresponding to the target pulse width adjustment parameters, and inputting the generated PWM waves to an LED driving circuit. With the intelligent lighting control system, the intelligent lighting control method and the intelligent lighting system provided by the technical schemes of the invention adopted, the requirements of an LED lighting device for MCU computing performance during dimming can be lowered.

Description

technical field [0001] The invention relates to the field of intelligent lighting, in particular to an intelligent lighting control system, a control method and an intelligent lighting system. Background technique [0002] Compared with traditional lighting equipment such as incandescent lamps and fluorescent lamps, Light Emitting Diode (LED) lighting technology has obvious advantages in energy saving, environmental protection, lifespan, color, volume, weight, etc., and has become the mainstream technology in the current lighting field. . [0003] In the field of intelligent lighting, according to the characteristics of LED lighting that can produce the three primary colors of red, green and blue, through the use of digital control technology, LED lighting can achieve colorful lighting requirements. LED lighting digital control technology usually adopts Pulse Width Modulation (PWM) method. For the three primary colors of cold light, warm light, and red-green-blue (Red-Green...
