摘要:
A lamp for general lighting applications utilizes solid state light emitters and provides light output that may approximate light emissions from of an incandescent lamp. An exemplary lamp includes a bulb and a pedestal extending into the bulb that supports the light emitters in orientations such that emissions from the emitters through the bulb approximate emissions from a filament of an incandescent lamp. An inner member around the emitters and the pedestal provides further light processing, e.g. diffusing and/or phosphor luminescence. The lamp conforms to form factors and/or uses lamp base connectors of common incandescent lamps and/or compact fluorescent lamps. For efficient substitution of components during manufacture of lamps to different specifications, at least some examples use modular couplings for the parts of the lamp to the heat sink or other housing, such as for couplings of the lamp base, the bulb and the inner light processing member (if provided).

Methods and systems for facilitating user interaction are described. One such method includes receiving, from a first user device, identification information associated with a targeted user and retrieving, from a database, contact information associated with the identification information. The method may further include providing the contact information to the first user device to facilitate communication between the first user device and a user device of the targeted user and/or providing a message to the user device of the targeted user.

Disclosed exemplary solid state light fixtures use optical cavities to combine or integrate light from LEDs or the like. In such a fixture, the cavity is formed by a light transmissive structure having a volume, and a diffuse reflector that covers a contoured portion of the structure. A heat sink member supports a flexible circuit board so as to position the light emitters to couple light to the transmissive structure and provide effective heat dissipation. The circuit board has flexible tabs mounting the emitters. When installed in the fixture, the tabs bend and the emitters press against a sufficiently rigid periphery of the light transmissive structure. TIM may be compressed between the heat sink member and the opposite surface of each tab. Heat conductive surface pads and heat conductors through vias through the tabs conduct heat from the emitters to the heat sink member, e.g. through the TIM.

A fin and tube assembly for use in a heat exchanger comprising a carbon steel tube, a carbon steel fin, and an external brazing compound comprising a material selected from the group consisting of nickel, chrome, copper, aluminum, zinc, and graphite brazed to the tube and fin is disclosed. A method for making the assembly and a power plant which includes the assembly are also disclosed. The brazing compound functions to prevent corrosion of the carbon steel and also functions to attach the tube and fin together.

A method and system for electronically communicating with a user knowing only a unique identifier associated with that user is described. An electronic message having an address based upon the unique identifier and consistent with an assigned convention is sent from a portable device and received by a server system. The message sent may include attachments such as, for example, pictures, audio and/or video files. The server system includes or is capable of accessing an electronic repository in which a plurality of unique identifiers are respectively associated with a corresponding plurality of profiles. Upon receipt at the server system, the message and any attachments are stored in association with a profile corresponding to the unique identifier. The server system then facilitates access to the message information and any attachments in accordance with the profile.

A lamp, for general lighting applications, utilizes solid state light emitting sources to produce and distribute white light. The exemplary lamp also includes elements to dissipate the heat generated by the solid state light emitting sources. The lamp includes a thermal handling system having a heat sink and a thermal core made of a thermally conductive material to dissipate the heat generated by the solid state light emitting sources to a point outside the lamp.
