Abstract
Abstract A mobile lighting system includes a self-powered mobile base that can be driven long distances and maneuvered in tight locations. An articulateable boom is mounted on the base and has multiple degrees of freedom of movement. A light array is attached to the end of the boom and has additional degrees of freedom of movement. One or more fixtures are mounted on the end of the boom and also have several degrees of freedom of movement, as well as having structure to vary the beam pattern output from each fixture. The system contains power generating means as well as all structure to operate the lights and the boom. Additional features which facilitate the efficient and advantageous provision of the mobile lighting system are also disclosed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
151 words
A quick release axially mounted metal halide lamp having an elongated lamp body positioned along a longitudinal axis, a center bulb surrounding arc electrodes, and end caps over end seals at opposite ends of the body, the lamp being axially mountable in a light fixture mount comprising: a connection means attached to one end of the lamp, the connection means including a portion extending away from the longitudinal axis of the body; and a quick release receiving means mounted in the light fixture mount, the receiving means comprising a clamp means movable by a control arm between an open position and a closed position, the clamp means allowing insertion or removal of the connection means when in the open position, and clamping and locking the connection means to the receiving means in the closed position, the receiving means also including biasing means to urge the clamp means to the closed position.
Claim 2
Dependent Claim
