SOLID-STATE LIGHTING DEVICES AND SYSTEMS

摘要

A solid-state lighting device for use in lieu of a gas discharge lamp, includes a housing; a lens coupled to the housing; a circuit board; and a plurality of solid-state light emitters carried by the circuit board and arranged to generate light to pass through the lens. An entirety of a form factor of the solid-state lighting device may be located within a cylindrical envelope having a length less than or about equal to an overall length of the gas discharge lamp and a diameter less than or about equal to the overall diameter of the gas discharge lamp. In addition, a light center length of the solid-state lighting device may be about equal to the light center length of the gas discharge lamp. Solid-state light emitters are arrayed with principal axes of emission radially spaced at least partially around and extending from a central axis of the lens.

1. A solid-state lighting device for use in lieu of a gas discharge lamp having an overall length, an overall diameter and a light center length, the solid-state lighting device comprising:
a housing; a lens coupled to the housing; a circuit board positioned within an interior of the solid-state lighting device collectively defined by the housing and the lens; a plurality of solid-state light emitters carried by the circuit board and arranged to generate light to pass through the lens; and a heat sink physically coupled to the circuit board to dissipate heat generated by the solid-state light emitters, wherein an entirety of a form factor of the solid-state lighting device defined by the housing and the lens is located within a cylindrical envelope having a length less than or equal to a scale factor times the overall length of the gas discharge lamp and a diameter less than or equal to the scale factor times the overall diameter of the gas discharge lamp, the scale factor being between about 1.25 and about 1.0, and wherein a light center length of the solid-state lighting device is within a range of about 1.1 to about 0.9 times the light center length of the gas discharge lamp.
