Abstract: Techniques are disclosed for providing an adaptive and scalable output drive current by a lighting driver, which helps mitigate issues related to binning of solid state light sources. The disclosed techniques may be implemented, for example, with the use of header pins and one or more jumpers or so-called shunt connectors. This allows for a given driver with a constant current output to provide any number of desired output drive currents on demand, by switching and/or adding and/or removing one or more shunt connectors across the appropriate header pins. The header may include any number of pin-pairs, with each pin-pair capable of receiving a shunt connector. Any number of driver topologies may be implemented with the header, such as flyback, buck, boost, buck-boost, and variants thereof.

Abstract: A lighting device including one or more solid state light sources providing air cooling of the electronic driver is disclosed. The driver receives power and provides it to the light source(s). The device also includes a first and a second housing. The first housing contains, at least in part, the driver, and includes a support having an exterior and an interior, that provides mechanical support to the second housing connected thereto. The interior includes a first opening. The second housing is a heat sink for the device. The second housing has an interior portion, with a second opening corresponding to the first opening, and an exterior portion, having a plurality of external openings. Air entering an external opening is able to mix with air in the first housing by flowing through the first opening and the corresponding second opening, which cools the electronic driver.
