Abstract: A simple do-it-myself lamp assembling structure comprises a lamp body and an inserting rod inserted to the lamp seat. The lamp seat has an inserting seat protrudes to a top side of the lamp seat. The lamp seat has locked with a confining reed and another end of the confining reed not being locked is inclined upwards as an inclined end. The inclined end is exactly inserted into the inserting rod to resist against the embedding groove. A lower end of a head of the inserting rod has an embedding groove. After the inserting rod has inserted into the embedding groove, the embedding groove is exactly buckled with the confining reed of the lamp seat. Thereby, a lamp assembling structure is formed which can be detached for storage and transfer with a small volume.

Abstract: An actively cooled recessed lighting trim apparatus is disclosed. The trim apparatus comprises a trim housing that fits within a standard recessed lighting fixture housing to define a space between the lighting fixture housing and the trim housing; a trim ring or face that has a vent for admitting a cooling fluid to the space; and a means for actively cooling the space or the trim housing. The space forms a low-pressure plenum through which a cooling fluid is circulated. A thermal protector may be secured within the trim housing to turn off a lamp in the housing if the internal temperature of the space, or of the trim housing, becomes too hot. The cooling means, which may be a fan, actively draws a cooling fluid in through the vent of the trim ring, over the trim housing and the illuminated lamp, and exhausts warmed cooling fluid out though gaps between the lamp and the trim ring. Accordingly, high-wattage lamps may be used safely in recessed lighting installations.

Abstract: A trim-ring auxiliary member system for capturing and supporting an auxiliary member relative to an interior and an open end of a lighting housing. The housing includes an annular groove formed in an interior of the housing. The groove is axially spaced from an open end of the housing. A support spring member is removably secured to the interior of the housing and disposed within and retained by the groove. A connecting spring removably attaches the auxiliary member to the support spring member.
