Abstract: A self-ballasted lamp includes: a base body; a light-emitting module and a globe which are provided at one end side of the base body; a cap provided at the other end side of the base body; and a lighting circuit housed between the base body and the cap. The light-emitting module has light-emitting portions each using a semiconductor light-emitting element, and a support portion projected at one end side of the base body, and the light-emitting portions are disposed at least on a circumferential surface of the support portion. A light-transmissive member is interposed between the light-emitting module and an inner face of the globe.

Abstract: To a constant-current power supply whose output current can be variably set, light emitting modules can be connected in parallel. A control unit recognizes connection information outputted from an information output unit provided in each of the light emitting modules and varies the output current of the constant-current power supply. Drive can be controlled in response to a state of the connected light emitting modules such as the connecting number of light emitting modules.

Abstract: A lighting device may include a substrate attached to one edge side of a radiator and a cover may be attached to cover the substrate. Heat-radiating fins may be provided on the other edge side of the radiator and an air-cooling unit may be rotatably provided inside the heat-radiating fins, thereby enabling freely rotation. In one or more examples, a case storing a circuit part is attached to the other edge side of the radiator and a cap is provided to the case. By the air flow from the air-cooling unit, the heat-radiating fins are caused to be a part of the ventilation path to allow for ventilation of the inside of the radiator.

Abstract: A bulb-type lamp includes a base body, a heat pipe, a light-emitting body, a cap and a lighting circuit. One end side of the heat pipe protrudes from one end side of the base body, and the other end side of the heat pipe is connected to the one end side of the base body. The light-emitting body includes plural LED elements, is connected to the one end side of the heat pipe, and is attached to the heat pipe to enable heat conduction. The cap is provided at the other end side of the base body. The lighting circuit is housed in the base body.
