First Claim
Patent Images
1. A safety helmet comprising:
- a cushioning layer having an inner surface;
an exterior shell covering at least a portion of the cushioning layer, said exterior shell having a heat dissipating portion having a thermal conductivity exceeding at least about 5 W/m*K;
a high power LED light having a power of at least about 1 W connected to and in thermal communication with the heat dissipating portion of the exterior shell whereby the heat dissipating portion provides a heat sink for the high power LED light;
wherein the heat dissipating portion further comprises an upper surface and the LED light further comprises an upper surface, and the upper surface of the LED light is located below the upper surface of the heat dissipating portion.

Abstract
A heat dissipating helmet provides a heat dissipating material portion. One or more high powered LEDs may be in thermal contact therewith providing a significant portion of a heat sink to remove heat from the LEDs to maintain them at a proper operating temperature during operation. The heat dissipating material may be also in contact with air flow as the helmet moves through space thereby allowing convection to assist in removing heat from the helmet. Furthermore, heat moving elements located internal to the helmet may assist in transferring heat to the heat dissipating material from the scalp of a wearer.

11. A safety helmet comprising:
-
a cushioning layer having an inner surface; a protective exterior shell exteriorly covering over the cushioning layer as a protective shell, said exterior shell having an exposed exterior heat dissipating portion having a thermal conductivity exceeding at least about 5 W/m*K; and a high power LED light having a power of at least about 1 W connected to and in thermal communication with the heat dissipating portion of other exterior side whereby the heat dissipating portion provides a heat sink for the high power LED light and provides structural integrity as a portion of the protective exterior shell; and wherein the heat dissipating portion further comprises an upper surface and the LED light further comprises an upper surface, and the upper surface of the LED light is located below the upper surface of the heat dissipating portion. - View Dependent Claims (12, 13, 14, 15, 16, 17)
