Solution Overview
Problem
Existing lighting systems with battery backup solutions lack efficient integration of AC power routing and emergency power supply mechanisms, particularly in scenarios where primary power is lost, leading to inadequate backup power delivery and reliability.
Innovation Solution
A lighting arrangement that includes a luminaire, a driver circuitry assembly, and a battery backup portion with a DC-AC inverter/converter and microcontroller unit to route AC power from either the external AC grid or batteries to the driver circuitry, ensuring continuous operation during power outages by selectively engaging the battery backup portion between the driver circuitry and the external AC grid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery backup portion is integrated into the lighting system, then reliability during power outages is improved, but device complexity increases
Solution Approach 1:
The patent combines the battery backup portion with the driver circuitry assembly into an integrated unit. The battery backup portion includes a DC-AC inverter/converter that is electrically connected to the driver circuitry, allowing the system to seamlessly switch between AC grid power and battery power without requiring separate backup systems.
Solution Approach 2:
The driver circuitry assembly serves multiple functions: it operates as a standard LED driver when AC power is available, and simultaneously functions as an emergency power source when AC power fails. The battery backup portion with its DC-AC inverter/converter provides both normal operating power conversion and emergency backup power, eliminating the need for dedicated emergency lighting systems.
2Adaptability or versatility
If the battery backup portion is selectively positioned between the driver circuitry and AC grid, then adaptability during power outages is improved, but device complexity increases
Solution Approach 1:
The system dynamically reconfigures its power routing based on the availability of AC grid power. The battery backup portion can be selectively positioned or engaged in the circuit, allowing the system to adapt between normal operation mode (AC grid powered) and emergency operation mode (battery powered). This dynamic reconfiguration provides flexibility without requiring multiple fixed circuit configurations.

AI summary
A lighting arrangement can include a luminaire, a driver circuitry assembly, and a battery backup portion. The luminaire can have light emitting diodes in an array string positioned in a first housing and a first wiring extending from the array string to a first plug connector. The driver circuitry assembly can drive the plurality of light emitting diodes and include circuitry with a rectifier and an IC chip positioned in a second housing and a second wiring extending from the circuitry to a second plug connector engageable with the first plug connector. The battery backup portion can be selectively positionable between the driver circuitry assembly and the external AC grid and have one or more batteries and a converter portion with a DC-AC inverter positioned in a third housing. The third housing and the second housing are interconnectable.
