Human-Factor Lamp System with Hierarchical Intensity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional lighting systems in large indoor environments, such as factories or warehouses, fail to adjust lighting effectively based on human presence, leading to unnecessary energy consumption and visual discomfort, as they lack the ability to synchronously adjust all lamps according to movement and require costly central control systems.
Innovation Solution
A human-factor lamp system with interconnected light emitting devices, each equipped with a control processor, dimming unit, identification unit, detection unit, transmitting unit, and receiving unit, which communicate to adjust lighting intensity based on the presence of people, using a hierarchical relationship to set luminous values and eliminate the need for a central control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If traditional lamps are used in large indoor environments, then consistent lighting is provided, but energy consumption increases unnecessarily when no people are present
Solution Approach 1:
The patent applies dynamics by making the lighting system adjustable and responsive to changing conditions. Each lamp can dynamically change its operational state based on real-time detection of human presence, transitioning between on and off states or adjusting brightness levels to match actual lighting needs, thereby reducing unnecessary energy consumption while maintaining reliability when needed.
Solution Approach 2:
The patent implements feedback mechanisms through sensors that continuously monitor the environment for human presence and feed this information back to the control system. This feedback loop enables the lamps to automatically adjust their operation based on detected conditions, turning off lamps when no people are present and turning them on when needed, thus optimizing energy usage without compromising lighting availability.
2Use of energy by stationary object
If sensors are provided to sense entry and exit of people, then lamps can be turned off to save energy, but additional network setup cost and control complexity are required
Solution Approach 1:
The patent applies segmentation by dividing the control system into independent units, with each lamp equipped with its own sensor and control circuitry. This modular approach eliminates the need for a complex central control system and extensive network infrastructure, as each lamp independently detects human presence and adjusts its operation locally, thereby reducing overall system complexity while maintaining energy-saving capabilities.
Solution Approach 2:
The patent implements self-service by enabling each lamp to autonomously detect human presence through integrated sensors and make independent control decisions without requiring external control signals. The lamps self-regulate their operation based on local environmental conditions, eliminating the need for complex centralized control systems and reducing both cost and complexity while achieving effective energy saving.
3Ease of operation
If lamps are turned on automatically after sensing condition is triggered, then lighting is provided when needed, but lamps cannot be synchronized to adjust all lamps according to movement of people
Solution Approach 1:
The patent applies merging by integrating multiple independent sensing and control functions into a unified system where all lamps work together in coordination. The sensing units detect human movement across the environment and the control system synchronizes lamp operation across multiple devices, merging individual lamp controls into a coordinated whole that responds uniformly to detected movement patterns, thereby achieving both automatic control and synchronous adjustment.

AI summary
A human-factor lamp and system capable of intelligently adjusting ambient light includes light emitting devices, each having a detection unit. When the detection unit detects a human within the lamps sensor field of view one of the light emitting device, such light emitting device is defined as a primary lamp and all others are defined as secondary lamps. The primary lamp is adjusted to a maximum luminous intensity and the secondary lamps are adjusted outwardly from the primary lamp and decremented to a minimum luminous intensity. When any secondary lamp is near more primary lamps away from different distances, the one with a larger luminous intensity is used as a basis for adjusting the brightness after the luminous intensity of the secondary lamp is decremented. In the environment having the human-factor lighting system, the overall ambient luminous performance can be changed according to the moving position of people.
