Abstract
A high efficiency LED billboard lighting system with four LED modules replacing existing lighting modules. Each module has six heat sink assemblies arranged in two rows. The heat sink assemblies comprise an LED package mounted on a heat sink reflector. The LED package has a flat fine diffusing lens positioned over the diode. A diffusing lens is spaced apart from the heat sink assemblies. An LED controller is provided for each module, with power factor corrected, switch mode Power Supply, where the secondary side can be connected directly to a battery to monitor and charge one or more battery, and can run directly from the battery.
Claims20
A lighting system comprising
- a first side lighting system comprising
- a plurality of lighting modules, each lighting module comprising
- a housing,
- a plurality of heat sink assemblies, each heat sink assembly comprising
- a heat sink reflector, wherein said heat sink reflector is designed to provide a uniformly lit surface by an asymmetric pattern,
- at least one LED package mounted with respect to the heat sink reflector, the LED package comprising
- a diode,
- a first refraction element, and
- a diffusing lens spaced apart from the first refraction element, and
- a first LED controller.
A method for providing lighting comprising
- providing a first side lighting system comprising
- a plurality of lighting modules, each lighting module comprising
- a housing,
- a plurality of heat sink assemblies, each heat sink assembly comprising
- a heat sink reflector,
- at least one LED package mounted with respect to the heat sink housing, the LED package comprising
- a diode,
- a first refraction element, and
- a diffusing lens, and
- a first LED controller and a plurality of other controllers;
- improving light capture and reducing the point source properties of each LED package by providing a phosphor diffuser area much larger than the diode cross section;
- designing the reflector to provide a uniformly lit surface by an asymmetric pattern;
- and optimizing refraction by spacing apart the first refraction element from the diffusing lens.
