Narrow LED spotlight beams have useful applications in the mining sector. Compared to a flood light beam, which is wide, such lighting configurations are tight and designed to illuminate targets located in far distances.
In the US, safety standards for mining luminaries are governed by MSHA. The organization ensures the equipment can withstand rough elements inside and outside the location. An example of an MSHA standard is the use of low voltage lighting inside mining areas.
Outside Mining Locations
Before actual mining takes place, the target location must first be surveyed and prepared. During this stage of the project, spot lights may already be frequently used. At elevated positions, LED light towers around the established perimeter can be setup to mark the area. On the ground, handheld spotlights are commonly utilized for general illumination.
During excavation, vehicles that operate at night benefit from narrow, intense spot beams. As trucks, lifters and other types of heavy-duty vehicles move materials in and out of the area, makeshift dirt roads and paths are often obscured. Such lights help improve visibility at the site.
Inside (Underground) Mining Locations
Underground mining sites require spot lights for increased safety. Hard hats with LED spot lights provide clarity in dark sections of the site. The units may also be equipped with flashing configurations for signaling, as well as different colors.
Various LED spotlight light colors are utilized to boost illumination in smoky or extremely dusty environments. When coupled with an intense spot light beam, underground miners are able work with better accuracy.
Depending on the task, LED mining lights should be equipped with explosion proof designs. For instance, non-sparking materials including copper-free aluminum with a powder coat finish perform well in combustible environments.
Hard or industrial-grade plastics and polycarbonate are also frequently preferred by mining operators. The materials are less prone to creating sources of ignition (sparks), compared to conventional metals.
