[0001] SELF-BALLASTED SOLID STATE LIGHTING DEVICES [0002]
The present invention relates to an integrated downlighting arrangement for a solid state light emitter comprising a light source / light engine, an energy transfer element and an electrical connector (e.g., for coupling with an Edison socket) in a single structure.
Much of the electricity produced in the United States each year (estimated at 25%) is used for lighting. Accordingly, there is a continuing need for providing more energy efficient lighting. The incandescent light bulb is known as an energy-efficient light source, and about 90% of the electricity it consumes is emitted as heat rather than light. Fluorescent lamps are more efficient than incandescent lamps (about 10 times), but still less efficient than solid-state light emitters such as light-emitting diodes.
In addition, compared to the normal life of solid state light emitters, incandescent lamps generally have a relatively short lifetime of about 750 to 1000 hours. In comparison, for example, light emitting diodes generally have a lifetime of 50,000 to 70,000 hours. Fluorescent lamps have a longer lifetime (e.g., 10000 to 20000 hours) than incandescent lamps, but provide less good color reproduction.
Another problem in conventional lighting fixtures is the need to periodically replace lighting devices (e.g., bulbs). Such problems are particularly noticeable when access is difficult (e.g., vaulted ceilings, piers, high-rise buildings, traffic tunnels) and / or replacement costs are extremely high. The typical lifetime of a typical installation is about 20 years, which corresponds to at least about 44000 hours of lighting use (based on 6 hours of use per day for 20 years). The lifetime of a light generating device is generally much shorter, thus necessitating a periodic replacement.
Therefore, for the above and other reasons, efforts have been made to develop a method by which solid state light emitters can be used in place of incandescent lamps, fluorescent lamps and other lighting devices in various applications. In addition, where light emitting diodes are already in use, efforts to provide light emitting diodes with improved energy efficiency, CRI Ra, contrast, light efficiency (lm / W) and / .
It is also possible to use a lighting device comprising a conventional light emitter (e.g., incandescent lamp, fluorescent lamp, etc.) and / or a solid state light emitter, wherein the components of the promoter are kept more firmly together, And / or there is a continuing need for more energy efficient lighting devices.
While well-designed solid-state light emitter based recessed downlights may appear to have a number of advantages over traditional lighting fixtures, it is still generally the case that a new type of lighting fixture can only be used in new buildings It can only be introduced. A more comprehensive solution is to replace the solid state light emitters and associated optics (replacing traditional lamps or light sources), power sources (traditionally ballasts), in-room structures (usually trim) In a single structure downlight product that can replace existing incandescent lamps in the market.
Such a solution is provided by an apparatus according to the present invention in which a user can select a solid-state light emitter-based installation for use with a conventional incandescent lamp, such as, for example, a conventional downlight " . The present invention provides a "self-ballasted" solid state light emitter illumination device. Thus, the homeowner, building owner, or contractor simply removes the lamps and trim from the traditional recessed downlight to reduce energy consumption, improve the aesthetics of the installation and improve the distribution of light, and replace them with the device according to the invention do. In terms of function, the device according to the present invention acts similarly to a self-ballasted compact fluorescent lamp, facilitating easy adaptation by allowing the consumer to take advantage of new technology while maintaining conventional conventional equipment constructions.
Some devices in accordance with the present invention require integration of a "trim" structure to transfer energy from a thermally sensitive solid state light emitter to an external environment, such that such a device provides mechanical maintenance separate from the trim, The trim (which normally fixes itself and the lamp in the can) can not be reused in this device. This can be accomplished by incorporating an integral Edison connector into the socket if the Edison socket is firmly mounted to a traditional can installation, or by a completely independent mechanical structure that does not depend entirely on the Edison socket for structural support (See, for example, Figs. 1 to 5).
