In this embodiment, the lamp cap module 15 includes a lamp cap inner tube 151, a conductive outer casing 153 and a conductive component 155. The conductive outer casing 153 is sleeved on the outer surface of the lamp cap inner tube 151. The conductive component 155 is plugged at a bottom of the lamp cap inner tube 151. The lamp cap inner tube 151 is made of insulation material. After the conductive outer casing 153 and the conductive component 155 are respectively combined with the lamp cap inner tube 151, the conductive outer casing 153 and the conductive component 155 serve as two electrical connection points to electrically connect to a power source.
Specifically, the lamp body 11 further includes a first conductive pin 116 and a second conductive pin 117. The first ends of the first conductive pin 116 and the second conductive pin 117 are respectively electrically connected to the two electrodes 190a of the first circuit board 190.

Because the conductive outer casing 153 is sleeved in the lamp cap inner tube 151, which means the conductive outer casing 153 serves as an electrical connection point, the second end of the first conductive pin 116 is inserted to the gap between the conductive outer casing 153 and the lamp cap inner tube 151 so that the second end of the first conductive pin 116 is electrically connected to the conductive outer casing 153.
Besides, the conductive component 155 is disposed through a connection hole 151a defined by the bottom of the lamp cap inner tube 151 so that at least a portion of the conductive component 155 is exposed outside the lamp cap inner tube 151 to serve as an electrical connection point. With such, the second end of the conductive pin 11 is inserted to the connection hole 151a to electrically connect to the conductive component 155.
With the above configuration, the first conductive pin 116 and the second conductive 117 perform electrical connection by respectively touching the conductive outer casing 153 and the conductive component 155. This makes assembling easier. No welding tools are necessary. Manufacturing efficiency is increased and cost is decreased.
Nevertheless, other alternative options may be applied if electrical connection is performed between the first circuit board 190 and the conductive outer casing 153 and the conductive component 155 and they are covered by the scope of the present invention.
