Abstract: Disclosed are a spike light and an outdoor lighting system. The outdoor lighting system comprises a power module, a relay module, spike lights and a PIR detection module, wherein the relay module receives a signal sent by the PIR detection module and transmits the signal to the power module; the power module receives and process the signal transmitted by the relay module, and meanwhile controls the on/off of the spike lights; the spike lights comprise a number of spike lights, each of which includes lighting lamp devices and a post, the lighting lamp devices being mounted on the post, electric wires being provided within the post; and, each of the lighting lamp devices comprises a lamp and a socket assembly, a pin electrically connected to the lighting lamp device being provided on the socket assembly, the pin being inserted into the post and puncturing the electric wires within the post.

Abstract: A lighting fixture includes a lamp body, a frame, and a light source is provided on the lamp body. Two bosses are provided on opposite sides of the outer wall of the lamp body. The frame includes a frame body, with positioning holes being provided at positions on the frame body corresponding to the bosses, and engaging seats corresponding to the positioning holes. The lighting fixture further includes at least two elastic sheets each including a main body portion and a buckle portion connected to the main body portion, an obliquely protruded tongue being provided on the main body portion, a neck and a fork being provided on the buckle portion. The main body portions of the elastic sheet are inserted into the engaging seats of the frame body and fixed in the positioning holes by the tongues.

Abstract: The present invention relates to a light-emitting diode (LED) lighting fixture, which comprises a radiator, a housing and an LED module mounted at the bottom of the radiator, and further comprises a lamp holder being fixed on the top of the radiator and running through the housing, an elastic element clamped between the lamp holder and the housing, and a lamp shade encircling the LED module.
