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 a judgment and protection type constant-current driving system for an architectural lighting LED lamp. The system is composed of a power supply input circuit, a current judgment circuit, a constant-current chip circuit and a driving output circuit. An auxiliary judgment circuit and a chip protection circuit are further arranged in the constant-current driving system. By means of the system, good stable currents can be obtained, output currents are kept constant, powered LED lamps are prevented from damage, the illumination effect is well improved, and illumination cost is reduced.

Description

technical field [0001] The invention belongs to the field of water pressure regulation systems, and specifically refers to a judgment and protection type constant current drive system for architectural lighting LED lamps. 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 electric energy. 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 an...
