An LED lighting device is disclosed. The LED lighting device includes an LED circuit having at least two LEDs that are mounted on a substrate and separated from each other by a distance of 3 millimeters or less. At least one of the at least two LEDs includes a different phosphor coating than that of at least one other LED of the at least two LEDs. The LED lighting device also includes a switch selectable by an end user to enable a change in a color of light emitted from the LED lighting device by causing one of at least a change in brightness or turning ‘on’ or ‘off’ the at least one LED with the different phosphor coating of the at least two LEDs in the LED circuit. The substrate and the switch are integrated within the LED lighting device.

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.

Provided is a switchable Correlated Color Temperature (CCT) illuminating device. The device may include a CCT switching unit, forming electrical connection with a drive power source, and a bulb shell, at least one filament being arranged inside the bulb shell, the filament including a substrate, and a first light-emitting unit group and a second light-emitting unit group arranged on the substrate and forming electrical connection with the CCT switching unit. Each of the first light-emitting unit group and the second light-emitting unit group comprises one or more light-emitting unit, the first light-emitting unit group and the second light-emitting unit group are connected in parallel and conducting directions thereof are opposite, and when one of the first light-emitting unit group and the second light-emitting unit group is in a positive ON status, the other is in a negative OFF status. When the CCT switching unit is in a first operating mode, the first light-emitting unit group is in the positive ON status, and the CCT switchable illuminating device emits light with a first CCT. When the CCT switching unit is in a second operating mode, the second light-emitting unit group is in electrical conduction, and the CCT switchable illuminating device emits light with a second CCT. Therefore, the problem that the illuminating device in the prior art has a single CCT is solved.
