The lamp housing 12 comprises an inner surface 12a and an outer surface 12b, wherein the inner surface 12a defines a first space 120. The connector 14 is connected to the lamp housing 12, wherein the connector 14 comprises a first electrical contact 14a and a second electrical contact 14b. The light source 10 is located in the first space 120; the lighting module 16 is located in the connector 14, and forms a second space 150 with the lamp housing 12.

The first protrusion 18-1 of the control module 18 passes through the lighting module 16 so that the wireless signal receiving element 182 is located in the second space 150. In one embodiment, the control module 18 crosses the lighting module 16, for example, the control module 18 is perpendicular to the lighting module 16, that is, the control module 18 and the lighting module 16 are at an angle of about 90 degrees. The first electrical contact 14a and the second electrical contact 14b of the connector 14 are electrically connected to the lighting module 16 through the first wire 141 and the second wire 142, respectively. The light source 10 is electrically connected to the lighting module 16 through the third wire 143 and the fourth wire 144, respectively, so that the external power source can input the driving signal to the light source 10 through the connector 14, the lighting module 16 and the first to fourth wires 141 to 144, wherein a protection element 19, such as a fuse, can be selectively connected in series between the second electrical contact 14b and the second wire 142 for over-current or over-voltage protection. The control module 18 is used to control the lighting module 16 so that the lighting module 16 adjusts the driving signal input to the light source 10 according to the internal control signal of the control module 18.
