A trouble light for car mechanics, etc., which utilizes magnets to position and mount the trouble light so as to more effectively direct light on to the desired work area. In particular, it is primarily designed for use in relatively close spaces where it is either inconvenient or impossible to employ conventional means such as a hook or a second person to position and direct the light. The light includes a bracket composed of a non-ferromagnetic material such as aluminum, a plurality of magnets mounted onto the bracket, a plurality of angular ferromagnetic pole pieces for mounting the magnets onto the bracket, and a heat shield for protecting the magnets from heat radiated by the light bulb. The bracket and the heat shield are mounted to the light housing of the trouble light such that the shield is interposed between the bracket and the housing.

A bracket member for attaching to a light reflector comprising a member having an upper surface, an inner surface, and a pair of lower edges, said bracket member being of non-ferromagnetic material and following substantially the contour of the reflector, said bracket member including a plurality of integral, flat, angular sections bent one with respect to the other and providing a corresponding plurality of flat upper surface sections on the bracket member, a heat shield strip of galvanized tin adapted to be interposed between the upper surface of the reflector and the inner surface of the bracket member and being of substantially the contour of the bracket member, the ends of the heat shield strip and the lower edges of the bracket member being adapted to be attached to the reflector, a plurality of permanent bar magnets of magnetized soft iron spaced about the upper surface of the bracket member along the flat sections thereof, and a corresponding plurality of ferromagnetic pairs of pole pieces for securing the magnets to the bracket member, each pair of pole pieces being associated with at least one of said magnets and being spaced, connected, and arranged about the upper surface of the bracket member along the flat sections thereof, each pole piece of each pair extending above the surface of the magnet associated therewith a distance approximately equal to the height of the magnet and also approximately equal to about one-half the width of the magnet thereby causing a reformation and intensification of the magnetic field in the area above the magnet and between the extensions of each of the pole piece pairs in order to increase the apparent strength of the magnets.
