A LED lamp or LED light bulb is an electric light for use in light fixtures that produces light using light-emitting diode (LED).LED lamps have a lifespan and electrical efficiency which can last up to 25 times longer than incandescent lamps, and are significantly more efficient than most fluorescent lamps,with some LED chips able to emit up to 303 lumens per watt.
A solar inverter or PV inverter, is a type of electrical converter which converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
Solar street lights are raised light sources which are powered by photovoltaic panels generally mounted on the lighting structure or integrated in the pole itself. The photovoltaic panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night.
There is nothing that highlights and emphasizes beautiful architecture or a well designed landscape quite like a carefully planned outdoor lighting scheme.Outdoor lighting design may seem like a daunting process, so consider the following preliminary questions before choosing the perfect outdoor lighting for your home.
