Abstract: A light-emitting diode (LED) lighting device includes a cover member that is configured to expose a protruding portion of a connection terminal when pressure is applied to the cover member and to cover the protruding portion of the connection terminal when the pressure is removed. Thus, an electric and/or mechanical safety problem caused by the connection terminal that is exposed to the outside may be reduced.

Abstract: An illuminating device includes a light source module; a heat radiator including a heat radiating plate having a cavity open toward a front surface thereof and receiving the light source module therein and ventilation holes disposed along an edge of the cavity, and heat radiating fins extending to a rear surface of the heat radiating plate, disposed in a radial manner along an edge of the heat radiating plate and positioned between the ventilation holes to form ventilation channels therebetween communicating with the ventilation holes; a cooler fixed to the heat radiator to be in contact with ends of the heat radiating fins and including air jet holes allowing air to be blown toward the heat radiator; and an electrical connector connected to the light source module and the cooler and supplying electrical signals thereto.
