Abstract

The invention relates generally to lighting and to a solution for powering an outdoor luminaire during the night. The system uses net energy metering mechanism to power up the luminaires that work on solar and wind power systems. A net metering module is connected to the ANSI PE receptacle kept on top of the luminaire. An input power port is provided to the module to take in power from solar and wind power systems. The power is conditioned and the excess generated is sent back into the grid by the PE receptacle. The net metering module measures the net power going to the luminaire or back to the grid. The advantages of the invention are that it provides for a quick hookup to an existing luminaire, eliminates the cost of battery and savings in cost as energy fed to the grid would be deducted from consumption during the night.

LUMINAIRE NET METERING DEVICE FOR SOLAR AND WIND POWER

BACKGROUND

The invention relates generally to energy efficient lighting and in particular to systems and methods for operating an outdoor luminaire during the night. The electric energy to operate an outdoor luminaire could be obtained from renewable energy sources such as solar and wind energy. However, outdoor luminaires require more power during the night than during the day. The required power to illuminate the luminaires during night time cannot be obtained from solar energy, and the renewable power may not always be available when required. One method to handle the situation is to power up a battery using the solar or wind power systems and to operate the luminaires using battery power. But battery storage is expensive to install and maintain and is inefficient because of the associated losses.

DETAILED DESCRIPTION

The invention discloses systems and methods for providing a light weight energy efficient solution for an outdoor luminaire to operate during the night, using mains power. The system uses net energy metering mechanism to power up the luminaire from solar and wind power systems. The luminaire comprises an ANSI PE receptacle to power ON and OFF the luminaire. DC power from the solar panel is converted to AC by an inverter to supply power to the receptacle. A net metering module is connected to the ANSI PE receptacle as shown in FIG. 1 kept on top of the luminaire. An input power port is provided on the module to take in power from solar and wind power systems. The power is conditioned and fed to the l...
