A lamp and an operating method for a lamp with an LED element 22 are described. An electrical circuit with the LED element 22 is covered by a cover member 12. A separation device 28 is provided to mechanically severe the electrical conductor 16a, 16b arrange to supply electrical power to the LED element 22 if the detector element 24 detects a defect of the cover member 12.

A mast lighting system of the type including at least one mast having a proximate end and an opposite distal end, the distal end capable of supporting an electrical component and the proximate end mounted to a foundation that has at least a portion extending into the ground, an electrical cable within the mast connecting the electrical component to a distribution component assembly through a breakaway electrical connector, and a power source connected to the distribution component assembly. The breakaway electrical connector including a fuse in a first part and a fuse clip in a second part forming the breakaway connection between the two parts of the electrical connector.

An LED tube lamp includes a lamp tube, an LED module, a power supply module, a micro switch, and an actuator. The lamp tube has pins for receiving an external driving signal. The power supply module is configured for supplying power to the LED module. The micro switch is coupled to the power supply module. And the actuator is configured to cause the micro switch to change to a closed-circuit position to allow the power supply module to supply power to the LED module for emitting light. When the LED tube lamp is properly installed into a lamp holder, the micro switch closes to electrically connect the power supply module to an external driving signal.

The invention relates to a LED electric bulb and a method of producing a LED electric bulb. The LED electric bulb comprises a glass bulb, a cap and a light generating module. The light generating module is at least partly received inside the glass bulb and is arranged in electrical contact with the cap. The light generating module comprises a driver PCB and a flexible, double folded strip forming two opposite legs comprising a plurality of LED's. The flexible, double folded strip is arranged to conform to and closely contact at least a portion of the interior surface of the glass bulb. The invention also relates to a semi-finished LED electric bulb and the use thereof for the production of a LED electric bulb.

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 lighting module includes a semiconductor laser element configured for emitting a laser beam in an emission cone, a light-emitting element, and a reflecting surface, a main portion of which reflects light coming from the light-emitting element in order to form an outgoing light beam. A secondary guiding face reflects the light coming from the first emission cone into a measurement cone. Also included is a device for detecting incident light exceeding a predetermined threshold of light intensity which is arranged within the measurement cone. The optical structure of the guiding face causes a spreading of the light so that the measurement cone exhibits an aperture angle greater than that of the first emission cone.
