A light-emitting diode (LED) luminaire controller comprising a transceiver circuit, a power converter circuit, and a control circuit is adopted to convert remote control signals into a pulse-width modulation (PWM) signal and a controllable DC voltage to operate an external LED luminaire by turning it on and off and controlling its luminous intensity. The LED luminaire controller 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 the PWM signal, the controllable DC voltage, and a metering command to the control circuit to request responses accordingly.

An LED tube lamp includes a lamp tube, having a first pin and a second pin for receiving an external driving signal; a first rectifying circuit for rectifying the external driving signal; a filtering circuit for producing a filtered signal; an LED lighting module configured for emitting light; and a ballast-compatible circuit, coupled to the first rectifying circuit, and containing a metallic electrode, a bimetallic strip, and a heating filament in an inert gas. A spacing is configured between the bimetallic strip and the metallic electrode, and the bimetallic strip includes two metallic strips with different temperature coefficients. When the external driving signal is initially input at the first pin and second pin, the ballast-compatible circuit will be in an open-circuit state, until entering a conduction state, which allows a current to flow through the LED lighting module thus allowing the LED tube lamp to emit light.

An energy efficient under-cabinet lighting system with a low profile switch mode power supply complying with Class 2 requirements. This power source is enclosed in a container to provide constant current to an array of light emitting diodes LEDs that are characterized by long life and low power usage. The system is designed to replace existing under-cabinet fluorescent lamp fixtures. A diffuser minimizes pixelization. The unit is also equipped with a safe-charge USB port that can safely charge lithium-ion batteries of accessories like tablets and cellphones with no danger of overheating their batteries.

A linear light-emitting diode (LED)-based solid-state lamp comprising electric shock and arc prevention switches, thermal protection devices, and bi-pins at the opposite ends normally operates with either an electronic ballast or AC mains. When such a lamp is installed in or uninstalled from a lamp fixture with the bi-pins in lamp sockets, the electric shock and arc prevention switches with double controls can work with the electronic ballast to prevent an electric arc from occurring not only between the lamp sockets and the bi-pins but also between electrical contacts in the electric shock and arc prevention switches. Together with the thermal protection devices, the lamp eliminates any possible fire hazard associated with the electric arc while maintaining electric shock free for installers.

A solid state lighting system performing color changes based on time of day. The light source may be an OLED panel, a quantum dot, pin point source. The light may be programed based on circadian rhythms, and may have separate controllers for each light source. T light may be a threaded lamp, or be installed into a fluorescent lamp fixture.

In order to add an emergency light function to a fluorescent LED lighting device, thereby increasing safety during a power outage, this LED lighting device, which can be mounted between a pair of sockets for fluorescent lighting, is equipped with a first power supply circuit, which lights the LED using direct current power obtained by converting/rectifying alternating current power supplied from the sockets, and a second power supply circuit, which lights the LED using an embedded battery. An embedded SW controller detects that a sudden drop in the current value or the voltage value in the lighting device, from a prescribed value Von when the lighting switch is turned on to a value that is essentially zero, occurs within a prescribed time T. When the sudden drop occurs two or more times in the prescribed time (FIG. 5), it is determined that a normal operation of turning off the light has been performed, and the light is turned off, and when the sudden drop occurs only once during the prescribed time (FIG. 6), it is determined that a power outage has occurred, and the LED is lighted as an emergency light using the second power supply circuit.

A tube lamp has a tubular portion that serves both as a light guide for energy from a solid state source and as a container for a material bearing a nanophosphor that is pumped by the energy from the source as the energy traverses the light guide. However, the tubular portion of the light guide also allows emission of light produced by the phosphor when excited. The material with the nanophosphor dispersed therein may appear either clear or translucent when the lamp is off and the nanophosphor is not excited by energy from the source.

An LED control system is provided for connection to an LED lighting system via a power line to control the LED lighting system using commands formed by manipulation of frequency and amplitude of a signal transmitted over the power line. The signal may be for example a wave or a sequence of pulses. The signal may be provided in superposition with line power or the line power may be formed as the signal.
