    摘要： A lighting device includes a casing having an inlet that introduces external air at one side and an outlet that discharges the introduced air at the other side. A fan is located within the casing to flow external air from an inlet direction to an outlet direction. An inlet cover blocks at least an upper area of the inlet to prevent external air from being directly introduced into the inlet. An air flow channel communicates the inlet and the outside, and includes two contracting flow channels having a reducing sectional area in an advancing direction of air. The two expanding flow channels communicate with the contracting flow channels and have an increasing sectional area in an advancing direction of air, so that in a connection portion of the contracting flow channel and the expanding flow channel, the advancing direction of air is changed.

    摘要： A light emitting diode (“LED”) module with improved thermal characteristics is provided. The module includes an LED, a first circuit board, a second circuit board, a lower insulator, an upper insulator, a lower contact, upper contacts, and a heat sink. Preferably, the heat sink comprises an outer housing and a contact ring. The LED and the heat sink are attached to the first circuit board via solder. In addition to serving as a substrate for the LED, the first circuit board (which contains a plurality of thermally conductive layers connected by vias) facilitates the transfer of heat away from the LED to the heat sink. The module also has improved mechanical and electrical properties, including redundant electrical connections, stable mechanical connections, and a shock-absorbing lower contact. The lower insulator can also be configured to prevent misalignment of the power source with the lower contact when the module is used in a flashlight or other lighting device.
