Abstract

An LED strip-shaped lamp with a connecting structure includes a first lamp housing, a plug disposed on the first lamp housing, a second lamp housing coupled with the first lamp housing, and a socket on the second lamp housing coupled to the plug. The plug includes a first magnet disposed at an end of the first lamp housing and a first electrical connector fixed in the first pad. The socket includes a second magnet at an end of the second lamp housing and a second electrical connector fixed in the second pad. When the magnets are coupled, the first and the second electrical connector are coupled to connect electrically. The magnets used in the connecting structure of the LED strip-shaped lamp of the present invention can be used as a structure for connecting the first and second lamp housing so as to simplify the connection of the strip-shaped lamps.

First claim

What is claimed is:

1 . An LED strip-shaped lamp with a connecting structure, comprising:
a first lamp housing, a plug disposed on the first lamp housing, a second lamp housing coupled with the first lamp housing, a socket on the second lamp housing and coupled to the plug; the plug comprising a first magnet disposed at an end of the first lamp housing and a first pad coupled within the first lamp housing, a first electrical connector fixed in the first pad; the first pad sandwiched between the first lamp housing and the first magnet; the socket comprising a second magnet disposed at an end of the second lamp housing and a second electrical connector fixed in the second pad, a second electrical connector fixed in the second pad; the second pad sandwiched between the second lamp housing and the second magnet; the first magnet and the second magnet attracting each other to couple the first lamp housing and the second lamp housing; when the first and second magnets are coupled, the first electrical connector and the second electrical connector being coupled to each other to connect electrically.

2 . The LED strip-shaped lamp with a connecting structure as claimed in claim 1 , wherein the first electrical connector is a contact piece, the second electrical connector is a elastic contactor, attraction force of the first and second magnets is greater than elastic force of the elastic contactor against the contact piece.

3 . The LED strip-shaped lamp with a connecting structure as claimed in claim 2 , wherein the LED strip-shaped lamp comprises two circuit boards respectively disposed in the first lamp housing and the second lamp housing, and the two circuit boards are respectively electrically connected with the contact piece and the elastic contactor.

4 . The LED strip-shaped lamp with a connecting structure as claimed in claim 2 , wherein the elastic contactor comprises a blind barrel closed at one end, an elastic member filled in the blind barrel, and a contactor hooked on the open end of the blind barrel.

5 . The LED strip-shaped lamp with a connecting structure as claimed in claim 4 , wherein the elastic contactor is made of a conductive material, the socket further comprises a spacer ring disposed between the elastic contactor and the second magnet, the spacer ring is made of insulating material.

6 . The LED strip-shaped lamp with a connecting structure as claimed in claim 5 , wherein an end of the blind barrel has a flange, the flange is sandwiched between the spacer ring and the second pad, and an end of the spacer ring comprises a flange ring sandwiched between the flange and the second magnet.

7 . The LED strip-shaped lamp with a connecting structure as claimed in claim 2 , wherein the plug further comprises a C-shaped clamping spring sandwiched between the first magnet and the contact piece to fix the relative position between the contact piece and the first pad.

8 . The LED strip-shaped lamp with a connecting structure as claimed in claim 1 , wherein cross-sectional shapes of the first and second magnets respectively are the same as that of the first lamp housing and the second lamp housing, and the first and second magnets respectively open a through hole along the central axis to facilitate passing the magnetic flux.

9 . The LED strip-shaped lamp with a connecting structure as claimed in claim 1 , wherein the first electrical connector is a socket hole, the second electrical connector is a pin, when the first and second magnets are coupled together, the pin is inserted in the socket hole to establish electrical connections.

10 . The LED strip-shaped lamp with a connecting structure as claimed in claim 1 , wherein the first and second pads are made of insulating material.
