| Abstract: |
This invention directs itself to a safety helmet to provide visibility of the wearer in a hostile environment such as smoke, dust and fog-like conditions. The safety helmet (10) includes a crown (18) and a brim section (20) surrounding the crown (18) and formed in one-piece formation with the crown (18). A flexible electroluminescent lamp rid (16) is mounted on the crown (18) or a transparent face shield (22) to provide electroluminescent light emission. The flexible electroluminescent lamp strip member (16) is electrically coupled to an electroluminescent actuating circuit (26) mounted on a rear section (14) of the safety helmet (10). Actuation of the electroluminescent lamp strip (16) allows for visual identification of the wearer and allows others in the vicinity to positionally locate the wearer of the electroluminescent lamp strip member (16).

What is claimed is:
1. A safety helmet having a frontal section and a rear section, comprising:
- (a) a brim portion formed on a lower portion thereof and having a frontal section and a rear section;
- (b) electroluminescent lamp means fixedly secured to said safety helmet for emitting electromagnetic radiation within a visible bandwidth of the electromagnetic energy spectrum;
- (c) means for electrically actuating said electroluminescent lamp means, said means for electrically actuating said electroluminescent lamp means being removably mounted to said rear section of said brim portion of said safety helmet and electrically coupled to said electroluminescent lamp means, said means for electrically actuating said electroluminescent lamp means including (a) an actuator housing, (b) inverter means located within said actuator housing for converting a DC signal to an AC signal for input to said electroluminescent lamp means, and (c) battery means disposed within said actuator housing for input of said DC signal to said inverter means; and,
- (d) motion sensing means electrically coupled to said electrically actuating means for strobing said electroluminescent lamp means alternately on and off responsive to detection of an absence of motion during a predetermined time interval, said means for electrically actuating said electroluminescent lamp means further including means for electrically coupling said motion sensing means intermediate said inverter means and said battery means.
