Abstract:
LED light bulbs include openings in base or cover portions, and optional forced flow elements, for convective cooling. Thermally conductive optically transmissive material may be used for cooling, optionally including fins. A LED light engine may be fabricated from a substrate via planar fabrication techniques and shaped to form a substantially rigid upright support structure. Mechanical, electrical, and thermal connections may be made between a LED light engine and a LED light bulb.
Abstract:
A method of forming a light bulb core, and a light bulb or lamp incorporating the core. The method includes forming a heat sink having at least six working facets located equally on opposite sides of a central plane, and then mounting a light source on each of the working facets. The light sources are mounted on circuit boards, each circuit board corresponding to a respective one of the working facets. The boards are then applied to respective working facets. The bulb is composed of a screw base, an external heat sink mounted in the screw base, and the light bulb core mounted in and extending from the external heat sink. The light source comprises a plurality of light emitting diodes.
Abstract:
The invention relates to an interface device comprising at least one module (1) provided with a first means (2) for connecting to an external network, and electronic device (3) for managing an external link, converting the external link protocol into an internal link protocol and for managing said internal link, a second means (4) for connecting to an equipment by the internal link and a reception area (5) for receiving the module (1), wherein said module (1) is embodied in such a way that it is removable, the reception area (5) and the module (1) are provided with a complementary means for guiding said module into the reception area (5) by bringing the second connecting means in line with the complementary equipment connecting means used in the form of a third connecting means (6).
