Problems solved by technology

[0002] Due to the backwardness of domestic technology, the constant current dimmer for navigation lights is not yet modular or completely modular, and there are still great deficiencies in maintainability, upgradeability and scale effect.
[0003] The existing constant current dimmers generally use single-chip microcomputers for signal processing and control signal sending in the control unit. Compared with PLC, the PLC system does not have stable operation.

Embodiment 1

[0038] Embodiment 1, a chopping type constant current dimmer, such as figure 1 shown, including the controller;

[0039] The modularized controller elektronikmodul controls the trigger pins of the thyristors D1 and D2 according to the collected current and voltage signals, so that the output current reaches the required constant current. Install a fuse at the incoming line end of the main circuit to form a protection against high current impact. Install a lightning arrester at the output end to prevent lightning impact at the output end.

[0040] After the positive pole of the input power supply passes through the fuse F1.1, the inductance coil L1 and the synchronous switch K1, the anti-parallel diode D1 and diode D2 are connected to one end of the inductance coil L2, and the inductance coil L1 is connected in series in the circuit. In addition, it also plays a role in smoothing the current.

[0041] The negative pole of the input power supply is connected to the other end ...

Abstract

The invention provides a chopping type constant-current dimmer. The chopping type constant-current dimmer comprises a controller; the positive pole of an input power supply passes through a fuse F1.1 and a synchronous switch K1 and then is connected with one end of an inductance coil L2 through a diode D1 and a diode D2 which are reversely connected in parallel, and the negative pole of the input power supply passes through a fuse F1.2 and a synchronous switch K2 and then is connected with the other end of the inductance coil L2; the input end of the inductance coil L4 is connected with the output end of the fuse F1.1 after passing through the fuse F5, and the output end of the inductance coil L4 is connected with the input end of the fuse F1.2 after passing through the fuse F7; the inductance coil L5 is respectively connected with an interface J1 and an interface J2 of the controller; and the dimmer has the advantages of maintainability, upgradability and large-scale effect. A PLC system is used, operation is stable and consistent, programming software and a manufacturing process are standardized, and the method is more suitable for development and application of a modular system.

Description

technical field [0001] The invention relates to a constant current dimmer, in particular to a chopping type constant current dimmer. Background technique [0002] Due to the backwardness of domestic technology, the constant current dimmers for navigation lights are not yet modularized or fully modularized, and there are still great deficiencies in maintainability, upgradeability and scale effect. [0003] Existing constant current dimmers generally use single-chip microcomputers in the control unit for signal processing and control signal sending. Compared with PLC, the PLC system does not have stable operation. Moreover, the PLC is consistent, and the programming software and production process are standardized, which is more suitable for the development and application of modular systems. [0004] Therefore, it is necessary to improve the prior art. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a high-effic...
