ABSTRACT:
Protective guard assemblies for light fixtures are designed especially for use in industrial environments, such as underground mining operations. Each assembly includes a reinforced cap and a base to which the light fixture is secured. The cap is installed over the fixture and secured to opposing sides of the base by hinges formed of mating sleeves. The base includes a cable support flange at one end. The support flange has two semi-circular notches on which the electrical cables are cradled to protect them from being damaged by outside impact. The cap includes a rear end plate with mating inverted semi-circular notches. With the cap installed on the base, the mating notches in the cap and base form circular apertures that firmly engage the two cables. The cap also includes a C-shaped hood extending from the rear end plate and over the cables and support flange to provide additional protection from outside impact.
