Abstract
Hazardous location lighting presents many challenges for illumination. The nature of the environment is such that if lighting fails it could be dangerous to the human operators of the equipment. If the lighting produced has high glare than the features of interest are difficult to distinguish further endangering the operators. A novel optical design is presented which improves glare through an indirect TIR + reflector optic which blends and hides direct view of the LED chips while producing a uniform intensity pattern which meets MSHA distribution requirements for continuous mining and roof bolter machines.
