Embodiment Construction

[0022] figure 1 A block diagram of an LED luminaire according to the invention is shown. The LED lamp 110 is used to replace a fluorescent lamp or an LED lamp that can operate normally with AC mains power in a normal mode. exist figure 1 In this example, LED light fixture 110 includes an emergency run portion 810, one or more LED arrays 214 having a forward voltage across it, and a power supply unit 311 to power one or more LED arrays 214 when the line voltage of AC mains is available. The emergency operation portion 810 includes an LED driver circuit 650 configured to provide emergency power (voltage and current) to drive the one or more LED arrays 214 when the line voltage of AC mains is not available. The power supply unit 311, originally designed to receive line voltage from AC mains for general lighting applications, is configured to operate in normal mode. The power supply unit 311 includes at least two electrical conductors “L” and “N”, a main full-wave rectifier 301...

Abstract

A light-emitting diode (LED) luminaire comprising an emergency-operated portion is used to replace a luminaire operated only in a normal mode with alternate-current (AC) mains. The emergency-operated portion comprises a rechargeable battery with a terminal voltage, a self-diagnostic circuit, and a transceiver circuit. The LED luminaire can auto-switch from the normal mode to an emergency mode or the other way around according to availability of the AC mains and whether a rechargeable battery test is initiated. The self-diagnostic circuit comprises timers and is configured to provide sequences and to auto-evaluate battery performance according to the sequences with the terminal voltage examined and test results stored. The LED luminaire further comprises a remote controller. When the remote control signals are initiated by the remote controller with phase-shift keying (PSK) signals transmitted, the transceiver circuit can demodulate such PSK signals and subsequently send commands to the self-diagnostic circuit to request responses accordingly.

Description

technical field [0001] The present invention relates to light-emitting diode (LED) light fixtures, and more particularly to LED light fixtures that include self-diagnostic circuitry to perform rechargeable battery self-checks based on a timing scheme set by multiple timers to ensure continued operation of the LED light fixture during power outages. Background technique [0002] Solid state lighting derived from semiconductor LEDs has thus far received a great deal of attention in general lighting applications. LED-based solid-state lighting will soon become the norm for general lighting due to its potential to be more energy-efficient, environmentally friendly (without the use of hazardous materials), more efficient, smaller, and longer-lived than traditional incandescent bulbs and fluorescent tubes. mainstream. At the same time, with the development of LED technology, driven by energy efficiency and clean technology on a global scale, more and more homes and organizations ...
