A luminaire assembly can include an enclosure top, and adapter coupled to the enclosure top, and a mounting accessory coupled to the adapter, where the mounting accessory is configured to secure the enclosure top to a structure.
A lighting assembly comprises a first lighting arrangement with a first lighting unit board and a first switched mode driving unit and a second lighting arrangement with a second lighting unit board and a second switched mode driving unit. A parasitic capacitance is present between the first and second lighting unit boards. The switched mode driving units switches voltages on the lighting arrangements and said voltages generates a differential voltage across the parasitic capacitance and leads to a leakage current. A blocking arrangement is in a path between the first and second lighting arrangements and it blocks the leakage current flowing at least from one of the first and second lighting arrangements to the other of the first and second lighting arrangements via the parasitic capacitance due to the differential voltage between the driving units. In this way, disturbances to the current regulation function in one of the driving units, caused by a parasitic current flow from the other driving unit, is prevented.

A DRIVER CIRCUIT AND A METHOD OF CONTROLLING A DRIVER
An isolated driver generates a PWM load drive level signal at the primary side and provides this to the secondary side via an optocoupler. Power consumption of the load is also sensed at the primary side. A drive level is sensed at the secondary side and compared at the secondary side with the load drive level to provide an error signal for the primary side controller. A frequency of the PWM load drive level signal is adjusted and the power consumption of the load is monitored in response to the frequency adjustment. The duty cycle of the PWM load drive level signal can then be adapted to compensate for errors introduced by the optocoupler.
A resonant converter has a resonant capacitor between the input stage and the output stage. An output inductor arrangement of the output stage has a first inductor component and a second inductor component. A first output is coupled to a reference output by both of the first and second inductor components in series and connects to a first load with a first (high) forward voltage. A second output is coupled to the reference output by only one of the first and second inductor components, and connects to a second load with a second (low) forward voltage. Only one output connects to a corresponding load at one time. This enables a large output voltage range with low total harmonic distortion and/or low voltage stress on the components of the input and output stages.
