The opening is configured to permit withdrawal of a user selected amount of the electrical wire from within the internal cavity and/or to permit a user selected amount of the electrical wire to be inserted into the internal cavity.04-12-2012
20130208474LED LIGHT BULB PROVIDIG HIGH HEAT DISSIPATION EFFICIENCY - An LED light bulb includes a lamp shell, a light emitting assembly and a power receiving base. The lamp shell includes a light transmissive portion and a holding portion. The light emitting assembly includes a light source baseboard located in the light transmissive portion and a circuit board connecting to the light source baseboard. The circuit board is surrounded by a heat sink. The heat sink includes a heat collecting section and a holding section extended from the heat collecting section into the power receiving base such that the power receiving base fully encases the heat sink without exposing. The inner surface of the power receiving base connects to the outer surface of the holding section so that heat generated by the light source baseboard is absorbed by the heat collecting section and transmitted via the holding section to the power receiving base for dissipating.08-15-2013
20130208475LUMINAIRE SYSTEM AND METHOD - A device, kit, and method for a luminaire having a first LED module with a first length and a plurality of LEDs, said LEDs disposed at predetermined pitch. A second LED module having a second length and a plurality of LEDs, said LEDs disposed at the same pitch as the first module. Wherein said first LED module and said second LED module have at least one LED disposed one half of the pitch from an edge of the LED module which when combined provide for uniform lighting across multiple LED modules. Certain embodiments may include one or more hubs for mounting the luminaire on predetermined centers.08-15-2013
