The present invention relates to an ambiance lighting system that more than one of a translucent panel aligned and connected together to form a perimeter having a top edge, and an interior region. A light control panel comprises one or more light-emitting diode (LED), and a power source. One or more of a sleeve have an open edge, the light control panel slides into the open edge and is retained in the sleeve, the sleeve is secured across the top edge of the translucent panel, the light control panel is orientated within the sleeve so that the LED illuminate the interior region projecting light through the translucent panel creating an ambiance lighting effect. Exemplary embodiments include a handle for carrying, use of Fresnel lenses, and creating a kit of ambiance lighting system parts that a consumer can assemble.

A decorative lamp includes a base; at least three LED circuit boards, a plurality of LED lamp beads distributed on an outer surface of each LED circuit board; a main control board electrically connected with the LED circuit boards and having a controller configured to send a timing signal; a driving power electrically connected with the main control board and having a PWM driving circuit electrically connected with the LED circuit boards, for receiving the timing signal sent by the controller and outputting a PWM signal according to the received timing signal; and a hollow lampshade surrounding the LED circuit boards and the main control board.

A fillable base for a portable light stand, the base including: a hollow structure made from moulded plastics material, the hollow structure having an upper portion and a lower portion with a generally circular footprint. The lower portion of the hollow structure has a substantially vertical cylindrical outer side wall, and the upper portion of the hollow structure has a conical outer side wall. The conical outer side wall has an outer edge extending from a top edge of the cylindrical side wall to an apex of the upper portion of the structure. The structure also has a recess that opens at the apex and within which one end of an elongate pole can be received.

A network is disclosed of a plurality of outdoor lighting units. Each lighting unit comprises a light fixture, for example a LED lamp; a power generating means, such as a solar panel or a wind turbine; and a storage means for electric energy, for example a battery.

The energy storage means of neighboring lighting units are connected by a conductor. An imbalance in power generation or power consumption results in a balancing current through the conductor. The balancing current equalizes the charge levels of the energy storage means in the system.

In an embodiment the conductor comprises a single core wire and ground.

Methods and apparatus for a security light having a remote photovoltaic module is set forth. The security light includes a primary rechargeable battery connected to the remote photovoltaic module while also having a backup battery system to be utilized when the rechargeable batteries condition require recharge. The security lighting unit functions as a security light to provide variable wide area illumination based upon environmental and battery conditions and also which power supply is optionally connected to the load, the load being the illumination sources and the various supportive electronics. The system further includes a controller which can not only operationally selects either the rechargeable batteries or backup batteries but also can monitor battery condition to preserve battery life. In operation, the security light may include a variable battery power supply for ease of installation.
