An apparatus, system, and method for lighting effects, including simulating a flame. A three dimensional carrier includes an array of a plurality of light sources distributed on it. A control circuit coordinates on/off of the light sources in a manner to simulate a jumping flame. In one embodiment, the three dimensional carrier and LEDs are encapsulated in an at least partially light transmissive cover. This light modular engine includes a control circuit and an interface to electrical power. The system can include the light engine in a light fixture such as an architectural fixture. The methodology can include a sequence of on/off and brightness variations for the array of light sources.

An LED lighting device or LED lamp comprising one or more LED packages; and a switch control unit is provided. The switch control unit is configured to operate the one or more LED packages. The switch control unit is in communication with a sensor located in a space, the LED lighting device or LED lamp also being located in the space. The switch control unit is configured to (i) receive a sensor signal from the sensor, (ii) process the sensor signal, (iii) determine an adjustment to the operating light qualities of the LED lighting device or LED lamp based on the processing of the sensor signal and one or more goal light qualities corresponding to the space, and (iv) adjust the operation of the one or more LED packages in accordance with the adjustment.

An adapter for connecting an LED light fixture to the threaded, screw-in socket of an Edison lamp holder. The adapter includes lever arms that toggle between a horizontal position and an inclined position. The inclined position of the lever arms poses a small outside diameter so the adapter can be inserted into the Edison socket without catching any of the socket threads. When fully seated inside the Edison socket, the lever arms are pushed into the horizontal position. A central core translating within the shell when pushed to the top position inside the shell locks the lever arms in the horizontal position. The lever arms when locked in the horizontal position define an outsider diameter larger than the internal diameter of the Edison socket to wedge the adapter therein.

A solar powered lamp attachment assembly for reducing energy consumption includes a base having an inner wall with a bottom end attached to a socket. The socket inserts into a porcelain lamp holder. An outer wall has an outer surface and a top surface. A plurality of lights is positioned on the top surface of the outer wall. A level switch on the outer surface includes a low button, a high button and a mid button. A solar panel is provides power to the plurality of lights. Additionally, a main switch is positioned on the outer surface of the outer wall of the base. The main switch includes a night button to enable a photoelectric cell, an actuator button to close or open electric power from the solar panel to the plurality of lights, and a plus button to enable a plurality of extra lights.

An LED lamp that can take the place of incandescent lamps. An elevated light source is positioned above a screw-type base. A first plurality of LEDs is connected in a series on one side of a flat substrate and a second plurality of LEDs, equal in number to the first, is connected in series on an opposite side of the substrate. Each LED of the first and second plurality of LEDs is mounted proximate a heat sink and a drive circuit is provided for the LEDs, with the drive circuit being located proximate and electrically connected to the screw base.

A threadless magnetic lightbulb and socket system includes a lightbulb base having a neck with a threadless exterior surface and a socket having a receptacle with a threadless interior surface configured to receive the neck. A first magnet is positioned at a tip of the lightbulb base and a second magnet is positioned in the receptacle of the socket such that the first magnet and the second magnet are configured to attract each other to magnetically retain the lightbulb within the socket. A threadless magnetic lightbulb includes a lightbulb base having a neck with a threadless exterior surface and a magnet positioned at a tip of the lightbulb base. A threadless magnetic socket includes a socket having a receptacle with a threadless interior surface configured to receive a lightbulb base and a magnet positioned in the receptacle of the socket.

A lamp cap can include: a metal shell; an insulating base disposed on the metal shell; an elastic connecting mechanism disposed on the insulating base, wherein the elastic connecting mechanism can include a first metal element connected to the insulating base, a second metal element disposed opposite to the first metal element, and a spring disposed between the first metal element and the second metal element and configured for supporting the second metal element and electrically communicating the first metal element and the second metal element, a main part of the second metal element can extend into the metal shell, when the main part of the second metal element is pressed by a threaded portion of a bulb, the spring can be compressed and the second metal element is movable relative to the insulating base.
