Abstract

The application discloses an LED dimmer, an LED dimming panel, an LED dimming method and an LED driving device. The LED dimmer includes: a dimming data generator for generating a pulse signal according to a start signal; a first adjusting device connected to the dimming data generator, wherein the dimming data generator The adjustment signal generates a pulse signal to represent the dimming data; the modulator is connected with the dimming data generator and is used to superimpose the AC input voltage and the pulse signal to generate a power carrier signal; and the second adjusting device is connected with the modulator connected, wherein, as an additional adjustment device, the second adjustment device uses its own on-off to transmit an additional dimming signal, wherein the power carrier signal and the additional dimming signal are used to control the LED lamp brightness and / or color temperature. Since two kinds of adjusting devices are contained in one dimmer, various control demands can be met, circuit cost can be reduced and reliability can be improved.

Description

technical field [0001] The present invention relates to light source control technology, and more specifically, relates to an LED dimmer for an LED lamp, an LED dimming panel, an LED dimming method and an LED driving device. Background technique [0002] When a light-emitting diode (light-emitting diode, LED) is used in the lighting field, an LED dimming device is used to adjust the brightness to meet the individual needs of users or adjust the light according to environmental requirements to reduce energy consumption. The brightness and color temperature of the LED can be adjusted by using the LED dimming device to meet the needs of users. [0003] The LED dimming device adopts, for example, a traditional thyristor dimmer. However, the thyristor dimmer has the problem of maintaining inconsistent current, and the products of different countries and brands are also different, which is prone to the problem of dimmer compatibility. In addition, phenomena such as flickering wi...
