Claims20
A fluorescent lampholder, comprising:
- a body member having a top portion and a bottom portion;
- and
- at least two lamp pin contact members mounted directly within the body member without any coupling arrangements to an external support structure positioned between respective lower portions of the at least two lamp pin contact members, wherein each respective lower portion is below a mid-point of each of the at least two lamp pin contact members;
- wherein the at least two lamp pin contact members are configured for enabling pins of a lamp inserted within the body member to contact and slide along an inner edge of the at least two lamp pin contact members, respectively, until the at least two pins contact one or more surface notches formed in a first end of the at least two pin contact members when the lamp is rotated, such that an axis of rotation of the lamp is normal to a flat surface of the first end, wherein the inner edge of the at least two lamp pin contact members is above the mid-point of the at least two lamp pin contact members;
- and
- wherein an end of each of the lamp pin contact members is configured to receive one or more conductors from a base plate of the bottom portion of the body member, the base plate used to support the body member in an upright position.
