An LED wall lamp, comprising a radiating metal shell; the radiating metal shell comprises an upper cover for installing a light source module and a lower cover for installing a power module; one side of the upper cover rotationally connects to one side of the lower cover in cooperation with a rotating shaft with a boss through a side slot for locating; the other side of the upper cover connects to the other side of the lower cover in a fastening manner through a screw structure. The LED wall lamp with an outer radiating shell of simpler connection structure, thus, no secondary possessing is needed and the assembly efficiency is higher.

An LED high bay light comprises a plurality of LED illuminant engines arranged abreast and alternately; each of the LED illuminant engine comprises an LED strip-shaped illuminant and an optical lens set covering the LED strip-shaped illuminant; the optical lens set comprises a plurality of strip-shaped optical lenses arranged conterminously; and two adjacent strip-shaped optical lenses are connected to each other through a mutual cooperation of the stepped spigots arranged oppositely. Each illuminant engine thereof adopts a structure of strip-shaped optical lens set with multiple sections, greatly reducing the difficulty in making molds and the cost for manufacturing parts.

A light emitting diode (LED) tube lamp configured to receive an external driving signal includes an LED module for emitting light, the LED module comprising an LED unit comprising an LED; a rectifying circuit for rectifying the external driving signal to produce a rectified signal, the rectifying circuit having a first output terminal and a second output terminal for outputting the rectified signal; a filtering circuit connected to the LED module, and configured to provide a filtered signal for the LED unit; and a protection circuit for providing protection for the LED tube lamp. The protection circuit includes a voltage divider comprising two elements connected in series between the first and second output terminals of the rectifying circuit, for producing a signal at a connection node between the two elements; and a control circuit coupled to the connection node between the two elements, for receiving, and detecting a state of, the signal at the connection node. The control circuit includes or is coupled to a switching circuit coupled to the rectifying circuit, and the switching circuit is configured to be triggered on or off by the detected state, upon the external driving signal being input to the LED tube lamp, to allow discontinuous current to flow through the LED unit.

A system and method of converting a light fixture from a conventional light fixture to an LED light fixture. Originally, the light fixture has a troffer, a ballast unit, and bulb receptacles. The conversion is accomplished by mounting a panel over the face of the troffer that obscures the ballast unit and bulb receptacles. LED light strips are mounted to the panel. Likewise, an LED power supply is mounted to the panel. The panel is attached to the troffer with a hinge connection. In this manner, the panel can be rotated away from the troffer for easy access.

An area light is provided including a housing defining a central axis having a first end, a second end opposite the first end, and a side portion; a cover mounted on the first end of the housing; a light module disposed on the first end of the housing, the light module comprising a heat sink and at least one light-emitting diode (LED) to emit light through the cover and in a direction that extends 360 degrees around the center axis; and a battery receptacle disposed on the side portion of the housing to receive a removable battery pack and supply electric power form the removable battery pack to the at least one LED. At least one hook is provided on or adjacent the first end of the housing.
