摘要：
The present invention provides a self-ballasted lamp which efficiently conducts heat of a plurality of LED chips of a light emitting module to its holder, and can prevent the temperature rise of the LED chips. The holder has a base portion, an edge portion provided at one end side of the base portion, which is thick at the base portion side thereof and thin at the distal end side thereof, and heat radiation fins provided at the other end side from the edge part and at the circumference of the base portion. The heat from the semiconductor light emitting elements is conducted from the base portion to the edge part and radiated therefrom. At this time, the edge part is thickened at the base portion side, wherein the thermal capacity is increased, and the heat conduction is improved.
