Battery-less red, green and blue LED wheel light for e.g. model construction car, has rectifier converting alternating current voltage into direct current voltage that charges high power capacitor and illuminates color-changeable LED

摘要

The wheel light has a round magnet (1), wire coil (2), and wire that is rolled up on a plastic sleeve which isolates the wire from ferrous sleeves, where an inner side of the magnet is hollow. A rectifier (3) converts the alternating current (AC) voltage into direct current (DC) voltage, where the produced DC voltage charges a high power capacitor (4) and illuminates a color-changeable red (R), green (G)and blue (B) LED (5).
