Solution Overview
Problem
Existing emergency lighting solutions require costly wiring installations and are not flexible enough to provide immediate and convenient illumination during power outages caused by events like typhoons, fires, or earthquakes.
Innovation Solution
A lighting apparatus with a detachable emergency light module that can be connected via a function interface, utilizing a driver circuit to convert external power into driving current for the light source, and including options for battery-powered operation or integration with a portable battery module, allowing for flexible light output and duration settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional emergency lighting systems are installed, then safety during power outages is improved, but installation cost and complexity increase due to wiring requirements
Solution Approach 1:
The emergency lighting system is divided into separate modular components: a detachable emergency light module containing the light source and battery, and a host lighting apparatus with a function interface. This segmentation eliminates the need for complex wiring installation while maintaining reliability, as the module can be simply attached to or removed from the host device via the function interface.
Solution Approach 2:
The function interface is designed to provide multiple functions: it serves as both a mounting structure for the emergency light module and an electrical connector for power transfer. This multi-functionality reduces the need for additional wiring and installation complexity while ensuring reliable operation during power outages.
2Reliability
If dedicated emergency light fixtures are installed, then emergency illumination is provided, but installation space and wiring cost increase
Solution Approach 1:
The emergency lighting function is merged with existing lighting apparatus by integrating a detachable emergency light module into the host device. This combination eliminates the need for separate dedicated emergency light fixtures and their associated installation space and wiring costs, while still providing reliable emergency illumination when attached.
3Reliability
If fixed emergency lighting systems are used, then continuous emergency light is available, but flexibility and ease of installation are reduced
Solution Approach 1:
The system transitions from a fixed emergency lighting installation to a dynamic, detachable module that can be easily attached to or removed from the host lighting apparatus. The function interface enables this dynamic configuration while ensuring continuous emergency light availability when the module is attached, thus maintaining reliability while dramatically improving installation flexibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables cost-effective, flexible, and convenient emergency lighting solutions that can be easily integrated into existing lighting systems, providing reliable illumination during power outages with adjustable light intensity and duration.
Implementation Method 1
The driver circuit is connected to an external power and converts the external power to a driving current supplied to the first light source
Implementation Method 2
Each LED module has a diffusion lens for changing light path by diffusing the light of the LED module
Implementation Method 3
a light guide plate for guiding the light of the first light source to enter from a lateral side of the light guide plate and escape from multiple tiny dots disposed on a flat surface of the light guide plate to generate a soft surface illumination
