The present invention discloses a modular lamp, including several modular units and lamp connectors, where the modular unit is a single lamp, and the lamp connector is configured to connect to the modular unit; and a male connector terminal on either side of each lamp connector is electrically plug-connected to a female connector terminal of one modular unit. In the present invention, female connector terminals connected to a power cable and a control cable are disposed on the modular unit, matched male connector terminals are disposed on the lamp connector, and the lamp connector is directly plug-connected to multiple modular units, so that the multiple modular units can be simultaneously physically and electrically connected to obtain the modular lamp. In this way, diversified lighting requirements can be met by adding different installation accessories to the modules. In addition, assembly operations can be completed by simply performing plugging and unplugging operations, without needing a professional to perform cable-connection and cable-routing between the modular units. Special scenario requirements such as good lighting effects and high ambient temperatures can be met by adjusting module power.

An elongated lighting module having an asymmetric illumination source formed from at least two rows of light emitting diodes (LEDs) that extend along the long axis of the module and are independently controllable. The lighting modules are powered via a wiring harness that extends down a support pole to a power converter stack having LED drivers to control the modules. The power supply for lighting module includes a power enclosure having individual light emitting drivers for powering the rows of light emitting diodes that can adjust the power level to compensate for the loss of power from another of the light emitting drivers. The power supply may also include a backup that can be switched over to power the rows of light emitting diodes in the event of a failure.
