Description

Technical Field

[0001] The present invention relates to the field of intelligent lighting technology, in particular to an intelligent energy-saving lighting system. Background Art

[0002] Currently, traditional lighting systems have many problems, such as high power consumption, single control method, low intelligence, etc. Although some existing intelligent lighting systems have realized remote control functions, they still have obvious shortcomings: The energy-saving logic is simple, and most of them rely on fixed time periods for control. They do not take into account dynamic factors such as real-time ambient lighting and personnel flow, which limits energy-saving efficiency. The sensor's sensitivity is low, resulting in a high delay in sensing ambient light intensity and human activity, which can easily lead to the situation where the light remains on even when people leave or remains on even when there is sufficient light. The system lacks a linkage mechanism with other intelligent fixture systems and cannot be coordinated and adjusted according to indoor humidity, temperature, door and window status, resulting in a poor user experience. Some systems use a single dimming mode and do not optimize brightness and color temperature for different scenarios (such as reading, resting, and meetings), which not only affects comfort but also causes energy waste.

[0003] Therefore, there is an urgent need for an intelligent energy-saving lighting system that can dynamically perceive the environment, accurately match needs, and deeply coordinate and link, so as to solve the shortcomings of energy saving, intelligence and adaptability in existing technologies.

[0009] Preferably, when the intelligent control module determines that there is human activity in the room based on the human infrared sensor, it determines the brightness that the LED light group needs to be controlled to achieve in combination with the light intensity signal detected by the light sensor. Specifically, when the light intensity is less than 200lux, the brightness of the LED light group is adjusted to 80%-100%; when the light intensity is 200<light intensity<300lux, the brightness of the LED light group is adjusted to 70%-100%; when the light intensity is greater than 300lux, the brightness of the LED light group is adjusted to 30%-60%, and when it is determined that the person has left, the LED light group is turned off after a delay of 10-30 seconds.

[0010] Preferably, the intelligent control module adjusts the LED light group to 6500K cold light when the indoor temperature is greater than 26°C based on the temperature and humidity sensor, and adjusts the LED light group to 3000K warm light when the indoor temperature is ≤26°C.

[0011] Preferably, the linkage interaction module adopts a WiFi communication module, a Bluetooth communication module or a ZigBee communication module.

[0012] Preferably, the intelligent control module adjusts the lighting state of the LED light group according to the working state of the smart home. Specifically, when it is determined that the indoor air-conditioning set temperature is 24°C, the LED light group is adjusted to 5000K neutral light.
