Embodiment Construction

[0020] DALI lighting controller of the present invention, as figure 1 As shown, it includes a power supply module 1, a dimming module 2, a microprocessor 3, a relay control module 4 and a DALI protocol transceiver circuit 5;

[0021] The power supply module 1 provides working power for the dimming module 2 , the microprocessor 3 and the relay control module 4 . Such as Figure 6 As shown, the power module 1 has four parts, the first part converts the mains AC220V to DC voltage 15V; the second part converts 15V to 12V through the voltage regulator module UM4 (L78M12); the third part converts 12V through the voltage regulator module UM5 (L78M05) into 5V; the fourth part converts 5V into 3.3V through the voltage regulator module UM13 (SPX1117M3-3.3).

[0022] Microprocessor 3 adopts Nuvoton's NUC100 series single-chip microcomputer, NUC100 series is embedded with Cortex-M0 core, the highest frequency can reach 50MHZ, has 32K bytes of Flash memory, 4K bytes of SRAM and 4K bytes ...

Abstract

The invention discloses a DALI lamp controller. The DALI lamp controller comprises a power module, a dimming module, a microprocessor, a relay control module and a DALI protocol transceiving circuit. The DALI protocol transceiving circuit is mainly composed of a rectifier bridge, a voltage stabilizing diode, two optocouplers and three common triodes, the circuit is simple in structure, the frequency of DALI signal conversion is low, DALI signal attenuation is low, signal packets are not prone to loss, DALI command signals are transmitted more stably, and the transmission distance is larger. Besides, according to the DALI lamp controller, small direct-current voltage is used for controlling a switch of alternating-current voltage, namely a relay in the relay control module is used for directly controlling the switch of a lamp, the phenomenon that the lamp emits micro-light after being turned off can be avoided without the need of controllable silicon, the circuit is simpler, and work reliability is improved.

Description

technical field [0001] The invention relates to a lamp controller, in particular to a DALI lamp controller. Background technique [0002] DALI (Digital Addressable Lighting Interface) is an international standard and popular lighting control protocol bus. It adopts Manchester-coded digital transmission and has powerful functions such as overall dimming, group dimming, address dimming and querying lamp status. Compared with the analog 0-10V dimming bus, this digital bus has the characteristics of accurate dimming, addressable, stable, centralized control, and convenient installation. [0003] DALI lighting controllers generally receive and send DALI signals through the DALI protocol transceiver circuit. The existing DALI protocol transceiver circuit, due to the complexity of the circuit, the DALI signal needs to undergo multiple conversions, the DALI signal attenuation is large, and the signal packet is easily lost. DALI signal transmission nearby. [0004] The "Digital Pha...
