QUARTZ LAMP WITH QUICK-RELEASE

摘要

A quartz lamp that permits the bulb (12) to be replaced from a side port (17) without disassembling the lamp housing, and without having to touch the quartz envelope of the bulb. The lamp has an access port (17) in a side wall of the lamp housing (10) through which an expired bulb is extracted and a replacement bulb is installed. A knob (20) seats in the access port (17) where it is lockable into its seated position. Attached to the inner surface of the knob is a first bulb holder assembly (28), which receives and holds the bulb at one of its ends and establishes electrical contact with the bulb at that end. A second bulb holder assembly (33) is secured within the lamp housing at a position opposite the access port (17) and in registration with the first bulb holder assembly (28). The second bulb holder assembly (33) receives and holds, and establishes electrical contact with, the bulb at the opposite end when it is inserted into the lamp housing through the access port. The second bulb holder (33) assembly mounted within the lamp housing may be electrically connected directly to an electrical power lead (47). The first bulb holder assembly (28) has a first electrical contact member (48) that is electrically connected to an electrical power lead (46) within the lamp housing and is secured within the lamp housing. A second electrical contact member (51) is mechanically and electrically secured to the first bulb holder assembly (28) and is arranged to electrically engage the first electrical contact member (48) when the knob is in its seated position so as to connect the power lead (46) to a bulb in the first bulb holder assembly when the bulb and assembly are inserted into the lamp housing and the knob is seated in the access port. Removal of the knob with attached first bulb holder assembly (28) thus permits the bulb to be changed without opening up the lamp housing.
