Abstract: The invention relates broadly to a fluorescent lamp construction adapted for use with hats or caps worn by workers in various occupations. The so-called hard hats are now largely worn by workers in hazardous locations, such as mining, construction, service and the like, and our improved fluorescent lamp construction is especially suited for attachment to a hard hat and the invention includes new and novel connection means.The fluorescent lamp is contained within an oblong housing that is removably held horizontally at the front of the hard hat and the lamp is energized by a battery which is carried on the person of the worker, such as by means of a carrying case having a clip for connecting it to a belt worn by the worker.To achieve a high level of light output at low temperatures, the invention includes means for conserving heat generated by the fluorescent lamp. Also, to reduce glare, the invention includes a new and novel means for dispersing the light from the lamp.
