    摘要: An LED lamp, in particular a table lamp, comprises a lighting head extending about a central axis; the head comprises: a body shaped as a ring about the axis and provided with a substantially annular seat; a plurality of LEDs arranged spaced apart from one another along the seat and about the axis and supported by a printed circuit board positioned in the seat and having a face, on which the LEDs are positioned, perpendicular to the axis; and a lens positioned in front of the LEDs to close the seat; the lens consists of a monolithic piece extending about the axis and has a concave annular inlet surface, facing the LEDs, and a convex annular outlet surface, substantially aligned parallel to the axis and extending about the axis and shaped so as to generate a rotosimmetric light emission about the axis.

    摘要: An LED chip module includes a first electrode plate and a second electrode plate. A first set of LED chip and a second set of LED chip are respectively set on the first electrode plate and the second electrode plate. The second set of LED chip is electrically connected to the first set of LED chip. A plastic shell is fixedly connected to the first electrode plate and the second electrode plate by injection molding to make the first electrode plate and the second electrode plate keep a predetermined space between each other and make a lower surface of the first electrode plate and a lower surface of the second electrode plate be respectively connected to two different polarity terminals of the power supply to drive the first set of LED chip and the second set of LED chip to emit light.

    摘要: In one embodiment, an overhead street light (a luminaire) is formed that has an asymmetric light intensity distribution, where the peak intensity is greatest along the direction of the street, lower directly across the street, and much lower on the house side of the street. Around the edge of a circular transparent light guide are white light LEDs that inject light into the light guide. To help control the asymmetry of the light intensity distribution, sawtooth-shaped grooves are formed in the light guide surface opposite to the light-emission surface and parallel to the street. Gaussian diffusers are used to partially diffuse the light. By proper selection of the grooves, the Gaussian diffuser, and the relative amounts of light emitted by LED segments around the light guide, the desired asymmetrical light intensity distribution is achieved while a direct view of the light exit surface appears as a uniform light.
