Abstract
A lighting device includes a light source, a housing, a heat radiator, and a connector. A part of heat generated by the light source is transmitted to the housing, and the housing radiates the part of the heat. Another part of the heat generated by the light source is transmitted to the heat radiator, and the heat radiator radiates the another part of the heat. The connector transmits heat from the housing to the heat radiator when a temperature of a portion of the housing around the connector is higher than a temperature of a portion of the heat radiator around the connector. The connector transmits heat from the heat radiator to the housing when the temperature of the portion of the heat radiator around the connector is higher than the temperature of the portion of the housing around the connector.
