Abstract

The invention discloses a control circuit compatible with a 0-10V light modulator and a TRAIC light modulator. The control circuit comprises a singlechip microcomputer, the TRAIC dimming circuit, a TRAIC signal generation circuit, an external voltage detection circuit and a PWM control silicon-controlled circuit, wherein the PWM control silicon-controlled circuit comprises a photoelectric couplerand a bidirectional silicon controller, the external voltage detection circuit is used for detecting an interface voltage, and the singlechip microcomputer is used for receiving and judging whether the TRAIC light modulator or the 0-10V light modulator is connected or not; when the TRAIC light modulator is connected, the bidirectional silicon controller is controlled to be conducted by the singlechip microcomputer, and a control signal of the TRAIC dimmer enters the TRAIC dimming circuit to achieve light modulation by the bidirectional silicon controller; and when the 0-10V light modulator isconnected, the singlechip microcomputer is used for converting the received voltage signal to a PWM signal output to control the bidirectional silicon controller to be conducted, a TRAIC signal is generated by the TRAIC signal generation circuit and is input to the TRAIC dimming circuit, so that light modulation is achieved.

Description

Technical field: [0001] The invention relates to the technical field of dimming, in particular to a control circuit compatible with a 0-10V dimmer and a TRAIC dimmer. Background technique: [0002] Nowadays, smart lamps are used more and more widely. In order to apply smart lamps in various occasions, people usually adjust the light intensity by connecting dimmers. Commonly used dimmers on the market mainly include TRAIC dimmers and There are two types of 0-10V dimmers, but the light control dimming circuit can only be connected to TRAIC dimmers, or can only be connected to 0-10V dimmers, which is very inflexible and inconvenient to use. [0003] In view of this, the inventor proposes the following technical solutions. Invention content: [0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a control circuit compatible with 0-10V dimmers and TRAIC dimmers. [0005] In order to solve the above-mentioned technical proble...
