Abstract

A decorative light with a structure that only allows the proper orientation between the LED and the power source is disclosed. The decorative light has a first positioning device provided between the light emitting diode and the socket, such that when the light emitting diode is inserted into the socket, the relationship therebetween ensures a predetermined orientation during the insertion of the light emitting diode into the socket. Furthermore, a second positioning device is provided between the socket and the base, such that when the socket is inserted into the base, the corresponding relationship therebetween ensures a predetermined orientation during the insertion of the socket into the base.

Claims

1. a decorative light comprising a base (10) having a first passage (12) defined therethrough and a second passage (13) defined to communicate with the first passage (12), a socket (20) detachably received in the first passage (12) of the base (10) and having a third passage (22) defined to communicate with the second passage (13), a light emitting diode (30) detachably received in the third passage (22) and two connecting plates (40) securely received in the inner periphery of the second passage (13), wherein the improvements comprise:

a first positioning device provided between the light emitting diode (30) and the socket (20) and having a rib (32) formed on the outer periphery of the LED (30) and a notch (222) defined in the inner periphery of the third passage (22) and corresponding to the rib (32) on the light emitting diode (30), thereby allowing the LED to be inserted into the socket in only one predetermined orientation; and

a second positioning device provided between the socket (20) and the base (10) and having a groove (23) defined in the outer periphery of the socket (20) and a lug (14) formed on the inner periphery of the first passage (12) to correspond to the groove (23) in the socket (20), thereby allowing the socket (20) to be inserted into the base (10) in only one predetermined orientation.

2. The decorative light as claimed in claim 1, wherein the first positioning device comprises a rib (32) formed on the outer periphery of the LED (30) and a notch (222) defined in the inner periphery of the third passage (22) and corresponding to the rib (32) on the light emitting diode (30).

4. The decorative light as claimed in claim 1, wherein the first positioning device comprises a first flattened face (36) formed on the outer periphery of the light emitting diode (30) and a second flattened face (226) formed on the inner periphery of the third passage (22) of the socket (20) corresponding to the first flattened face (36), whereby when the light emitting diode (30) is inserted into the third passage (22), the relationship between the light emitting diode (30) and the socket (20) allows only one predetermined orientation during the insertion of the light emitting diode (30) into the socket (20).

5. The decorative light as claimed in claim 1 further comprising a second positioning device provided between the socket (20) and the base (10) thereby allowing the socket (20) to be inserted into the base (10) in only one predetermined orientation.

6. The decorative light as claimed in claim 5, wherein the second positioning device comprises a groove (23) defined in the outer periphery of the socket (20) and a lug (14) formed on the inner periphery of the first passage (12) and corresponding to the groove (23) in the socket (20).

7. The decorative light as claimed in claim 5, wherein the second positioning device comprises a first flattened face (24) formed on the socket (20) and a second flattened face (141) formed to correspond to the first flattened face (24);

whereby when the socket (20) is inserted into the first passage (12), the first and the second flattened faces (24,141) allow only one predetermined orientation.

8. The decorative light as claimed in claim 5, wherein the second positioning device comprises a groove (23) defined in the outer periphery of the socket (2) and a lug (13) formed in the inner periphery of the first passage (12) corresponding to the groove (23) of the socket (20), whereby when the socket (20) is inserted into the base (10), the relationship between the groove (23) and the lug (13) allows only one predetermined orientation during the insertion of the socket (20) into the base (10).

3. The decorative light as claimed in 1, wherein the first positioning device comprises a groove (34) defined in the outer periphery of the light emitting diode (30) and a rib (224) formed on the inner periphery of the third passage (22) to correspond to the groove (34) of the light emitting diode (30).

9. A decorative light comprising a base (10) having a first passage (12) defined therethrough and a second passage (13) defined to communicate with the first passage (12), a socket (20) detachably received in the first passage (12) of the base (10) and having a third passage (22) defined to communicate with the second passage (13), a light emitting diode (30) detachably receive din the third passage (22) and two connecting plates (40) securely received in the inner periphery of the second passage (13), wherein the improvement comprises:

a first positioning device provided between the light emitting diode (30) and the socket (20) and having a groove (34) defined in the outer periphery of the light emitting diode (30) and a rib (224) formed on the inner periphery of the third passage (22) to correspond to the groove (34) of the light emitting diode (30); and

a second positioning device having a first flattened face (24) formed on the socket (20) and a second flattened face (141) formed on the inner periphery defining the first passage (12) to correspond to the first flattened face (24);

whereby when the socket (20) is inserted into the first passage (12) of the base (10), the first and the second flattened faces (24,141) allow only one predetermined orientation.
