Abstract

A signal lamp assembly including a casing fixed to the spokes of a bicycle wheel, two tubular, light permeable lampshades connected to two opposite ends of the casing, and a lamp circuit unit installed in the casing and the lampshades and consisting of a battery, a manual switch, a reversing switch, and a series of light emitting diodes disposed in the lampshades and controlled to give light by the manual switch and the reversing switch, wherein the reversing switch is alternatively switched on and off when the bicycle wheel is turned round and round after the manual switch is switched on, causing the light emitting diodes to flash.

Claims

1. A signal lamp assembly comprising:

a hollow casing fixed to a bicycle wheel, said casing comprising a mounting recess, which receives a wheel hub of the bicycle wheel, and fastening means, which secures said casing to the spokes of the bicycle wheel;

two tubular, light permeable lampshades connected to two opposite ends of said hollow casing;

a lamp circuit unit installed in said casing and said lampshades, said lamp circuit unit comprising a battery power supply, a manual switch, a reversing switch, and a plurality of light emitting diodes disposed in said lampshades and connected in series to said battery power supply through said manual switch and said reversing switch, and

wherein said reversing switch is alternatively switched on and off when the bicycle wheel is turned round and round after said manual switch is switched on, causing said light emitting diodes to flash.

2. The signal lamp assembly of claim 1 wherein said reversing switch comprises a liquid metal inside moved between a closed position to switch on said reversing switch and an open position to switch off said reversing switch.

3. The signal lamp assembly of claim 1 wherein said reversing switch comprises a contact metal ball moved between a closed position to switch on said reversing switch and an open position to switch off said reversing switch.

4. The signal lamp assembly of claim 1 wherein said reversing switch comprises two contact metal springs spaced at one side and respectively connected to two opposite terminals of said battery power supply, and a magnet moved between a closed position to attract said contact metal springs causing them electrically connected, and an open position to release said contact metal springs causing them electrically disconnected.

5. The signal lamp assembly of claim 1 wherein said lampshades are respectively fastened to the two opposite ends of said casing by respective screw joints and respectively sealed by a respective water sealing ring.
