SINGLE-WIRE DIMMING METHOD

摘要

A single-wire dimming method is provided in the present invention. The method is adapted for a lamp with a first color light source and a second color light source. The method includes: providing a dimming control interface, wherein the power voltage is chopped when the dimming control interface is operated; dividing a period of the power voltage into a first phase period, a second phase period and a third phase period; chopping the power voltage at the first phase period when a user adjust the dimming control interface to turn on a first color light; chopping the power voltage at the second phase period when a user adjust the dimming control interface to turn on a second color light; chopping the power voltage at the third phase period when a user adjust the dimming control interface to turn on a mix color light, wherein the mix color light is to combine the first color light and the second color light.

1. A single-wire dimming method, adapted for a dimmable lamp, wherein the dimmable lamp comprises at least a first color lamp and a second color lamp, wherein a control circuit of the dimmable lamp receives a power voltage, and controls the first color lamp and a second color lamp, wherein the single-wire dimming method comprises:
providing a dimming interface, wherein the power voltage is chopped when the dimming interface is operated; dividing a AC period of the power voltage into a first phase period, a second phase period and a third phase period; chopping the power voltage at the first phase period when a user adjusts the dimmable lamp to show a first color light by the dimmable lamp; chopping the power voltage at the third phase period when a user adjusts the dimmable lamp to show a second color light by the dimmable lamp; and chopping the power voltage at the second phase period when a user adjusts the dimmable lamp to show a mixed color light by the dimmable lamp, wherein the mixed color light is mixed by the first color light and the second color light.
