BLE LED Driver Configuration Without Mains Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED driver configuration methods, such as NFC, face limitations in range and bandwidth, making it difficult to configure multiple drivers stacked on a shelf or pallet without a mains supply, leading to potential errors and damage.
Innovation Solution
Utilizing Bluetooth Low Energy (BLE) transceivers with an on-board power supply to enable wireless configuration of LED drivers before installation, allowing identification and configuration via a portable device, and subsequent connection to a mains supply for further configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If NFC technology is used for wireless configuration of LED drivers, then configuration can be performed without mains supply connection, but the range is limited and cannot accommodate multiple stacked LED drivers
Solution Approach 1:
The patent changes the communication technology parameter from NFC to Bluetooth Low Energy (BLE), which fundamentally alters the range and capability parameters. BLE operates at 2.4 GHz with significantly longer range than NFC, enabling configuration of LED drivers stacked on shelves or pallets without requiring physical proximity or line-of-sight contact.
2Ease of operation
If NFC technology is used for wireless configuration, then configuration can be performed without mains supply, but the memory size and bandwidth are insufficient for comprehensive configuration
Solution Approach 1:
The patent changes the communication protocol parameter from NFC to Bluetooth Low Energy, which provides superior bandwidth and memory capacity. BLE can handle more complex configuration data packets, enabling comprehensive parameter setting including multiple LED strings, dimming curves, color temperature profiles, and firmware update capabilities that exceed NFC limitations.
3Reliability
If LED drivers are configured after installation, then configuration can be performed with mains supply connection, but errors and damage may occur during installation due to incorrect settings
Solution Approach 1:
The patent enables preliminary configuration action before installation by providing wireless configuration capability without mains supply connection. The LED driver can be configured with correct operational parameters, dimming characteristics, and protection settings in advance, then installed directly into the application without requiring subsequent configuration steps that could introduce errors.
4Productivity
If multiple LED drivers are stacked on shelves or pallets, then storage and transport is efficient, but configuration becomes difficult without individual access
Solution Approach 1:
The patent changes the wireless communication range parameter by switching from NFC to Bluetooth Low Energy. This extended range enables a user to configure multiple LED drivers stacked on shelves or pallets from a single location without needing to physically access or move individual drivers, maintaining storage efficiency while improving configuration accessibility.
