  • Patent number: 6193534
    Abstract: A fluorescent lamp holder assembly is adapted to receive various injection molded end cap structures allowing the fluorescent lamp holder assembly to have several embodiments, including watertight embodiments. The fluorescent lamp holder assembly may be disposable or may allow replacement of the fluorescent lamp, with the replacement style being watertight. The fluorescent lamp holder assembly generally includes a fluorescent lamp surrounded by a protective sleeve. A first end cap covers a first end of the lamp and sleeve, while a second end cap structure comprising a power connector cap and tube power connector cap covers a second end of the lamp and sleeve. In one embodiment, the protective sleeve is a structure that includes inner and outer co-axial tubes with a plurality of spacers or creases therebetween and/or therein defining a plurality of chambers defining a plurality of air pockets. The air pockets provide insulation for assisting in cold starting of the fluorescent lamp.

  • Patent number: 6190200
    Abstract: Apparatus and method for providing simple and effective attachment of a lamp holder base to a mounting plate includes providing in the mounting plate an opening having a wide opening portion and a relatively narrower opening portion, which together define at least one mounting tab of the mounting plate, the mounting plate further having an outer surface and a latch edge portion; providing on the lamp holder base an elongated body and a latch member, the elongated body including at least one mounting channel having a base surface and an inclined surface which define a first channel opening and a second channel opening, the inclined surface terminating at the first channel opening to define a pivot edge, the latch member including a latch surface region; inserting the elongated body in the wide opening portion until a cross section of the mounting plate is generally aligned with one of the first channel opening and the second channel opening; moving the mounting plate in a direction such that the at least one m

  • Patent number: 6159029
    Abstract: A lamp holder carries a fluorescent lamp which includes first and second contact pins, with each contact pin having a diameter. The lamp holder includes a socket having a pair of walls defining a clearance distance therebetween which is at all times greater than the diameter of the contact pins. The walls define a slot therebetween, the slot configured for receiving the contact pins therein. At least one of the walls has a first notch for receiving the first contact pin therein. The lamp holder also includes an electrically conductive terminal associated with the slot for providing power to the second contact pin. The terminal is configured for melting when being an electrode of an electric arc discharge, thereby discontinuing the electric arc discharge.

  • Patent number: 5688139
    Abstract: The invention is directed to a lamp holder for carrying a fluorescent lamp, including two contact pins, with each contact pin having a diameter. A socket includes an inner hub, two slots and a conductor. The two slots are disposed on opposite sides of the inner hub. A spring biases the contact pins out of the slots. The conductor is associated with each slot, and is configured to engage each contact pin of the fluorescent lamp. The conductor and the inner hub define a clearance distance therebetween in a direction transverse to a longitudinal direction of each slot, with the clearance distance at all times being greater than the diameter of the contact pins. The clearance distance allows the contact pins to be moved away from the conductor by the spring, to thereby prevent electrical arcing when one of the contact pins is not fully engaged with the conductor.
