Smart Lighting Control Device Standby Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart lighting systems consume significant standby power due to milliamp-level currents even when not in use, particularly when connected to high-voltage environments, necessitating a reduction to microamp-level consumption.
Innovation Solution
A smart lighting control device comprising a control module, standby processing module, and logic control module, which processes digital signal control instructions to enable or disable components based on flag bit and standby instruction bits, reducing power consumption by controlling the lamp's operation and transitioning components to a standby state when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all modules (except lamp load) remain in working state during standby mode, then the system maintains readiness for immediate operation, but standby power consumption increases to milliamp level
Solution Approach 1:
The system is divided into multiple independent modules (control module, standby processing module, data transmission module, logic control module) that can be independently controlled. During standby mode, only essential modules remain active while non-essential modules are disabled, allowing the system to maintain basic functionality with reduced power consumption from milliamp to microamp level.
2Use of energy by moving object
If modules are disabled to reduce standby power consumption, then power usage decreases to microamp level, but system response time and reliability may be affected
Solution Approach 1:
The control module continuously monitors and maintains readiness by keeping essential processing capabilities active in standby mode. When a control instruction is received, the system can immediately process and respond without requiring full module activation, thus achieving microamp-level power consumption while maintaining reliable response capability.
Solution Approach 2:
The system employs periodic sampling of control instructions by the data transmission module, which receives and samples instructions at appropriate intervals during standby mode. This periodic action allows the system to remain power-efficient while still detecting and responding to control signals when needed.

AI summary
The application provides a smart lighting control device capable of reducing standby power consumption, wherein a control instruction is received by a control module, then an enable signal is sent by a standby processing module according to status of a flag bit signal of the control instruction to a data transmission module and a logic control module; and the data transmission module receives the control instruction according to the enable signal and transmits a sampled control instruction to the logic control module; and the logic control module controls a lamp according to the control instruction when a standby instruction bit is invalid, and sends a standby instruction to the standby processing module when the standby instruction bit is valid; and the standby processing module disable the data transmission module and the logic control module according to the standby instruction, thereby standby power consumption of the lamp is reduced.
