Problems solved by technology

In the power supply process of the building lighting system, the fluctuation of the current is unavoidable, and the LED lamp needs a relatively stable current condition when it is used. If the current fluctuates frequently, it will not only affect the lighting effect, but also cause the LED lamp to flicker. It will also greatly reduce the service life of LED lights and greatly increase the cost of lighting

Abstract

The invention discloses an architectural-lighting LED-lamp constant-current driving system based on a chip protection circuit. The constant-current driving system is composed of a power input circuit, a current determining circuit, a constant-current chip circuit and a driving output circuit, and a chip protection circuit is further arranged in the constant-current driving system. By means of the architectural-lighting LED-lamp constant-current driving system based on the chip protection circuit, a current can be well steadied, an output current is kept constant accordingly, it is avoided that an electric LED lamp is damaged, the lighting effect is well improved, and lighting cost is reduced.

Description

technical field [0001] The invention belongs to the field of water pressure regulating systems, and in particular refers to a constant current drive system for building lighting LED lamps based on a chip protection circuit. Background technique [0002] In buildings, the lighting system is an indispensable system, and at the same time it is also a large power consumer, which needs to invest a lot of electricity. Compared with ordinary lighting, the owner of high-power LED lights has better luminous effect and saves energy. Therefore, most of the lighting systems in buildings today use LED lighting systems. In the power supply process of the building lighting system, the fluctuation of the current is unavoidable, and the LED lamp needs a relatively stable current condition when it is used. If the current fluctuates frequently, it will not only affect the lighting effect, but also cause the LED lamp to flicker. It will also greatly reduce the service life of the LED lamp and ...
