In certain embodiments, provided is intelligent solar powered lamps and methods of controlling operation of the same. In one example, the intelligent solar powered lamp comprises a LED component; a solar panel component; a battery component; a converter that operatively connects with the LED component, solar panel component and the battery component; and a microcontroller that operatively connects with the battery component and electrically communicates with the converter. In some embodiments, the microcontroller comprises a memory that stores an executable, software program configured to control the operation of the lamp. Other embodiments are described herein. In certain embodiments, the intelligent solar powered lamps provide an intelligent mode which utilizes machine learning technologies to optimize operations and to maximize performance and user experience.

An emergency lighting assembly is provided having a housing with one or more adjustable lamp assemblies for aiming the light at selected areas. The lamp assembly is mounted in the housing by a ball and socket arrangement. The lamp assembly has a substantially spherical shape with a front section made of a heat conducting material and a rear section made of a plastic material. The front section has an opening on a front side having a lens and a base spaced from the front side supporting the light source. The light source in one embodiment is an LED which is coupled to the front section to conduct heat from the LED away from the LED and the housing. The rear section has an opening in the rear side that receives a fixed stop member to limit pivoting movement of the lamp assembly with respect to the housing. The rear section also includes a projection oriented to contact the stop member to limit rotation of the lamp assembly with respect to the housing.

A LED based lighting apparatus is disclosed. The light engine used in the lighting apparatus may use printed circuit board and have a plurality of LED groups that are independently controllable by a control unit. The power supply input and return paths connected to each LED group may be implemented on different layers to allow a compact footprint that may be used with traditional fluorescent encasements with relatively little modification. The LEDs may comprise a subset of LEDs having a first color and a subset of LEDs having a second color different from said first color intertwined on the light engine.

An integrated mechanical fixing and electrical connection system, comprising a junction box and a lighting fixture, wherein the junction box includes a first multipolar electrical connector for the electrical connection of the lighting fixture to the mains power supply of a system, a coupling mechanism and a second electrical connector for fixing and electrical connection of the lighting fixture to the junction box, a compartment adapted for housing accessories for the lighting fixture and an internal space available to the installer for the wiring of the electrical system which passes in correspondence of the fittings placed laterally and/or on the bottom of the junction box.
