Embodiment

[0014] Such as figure 1 For the driving power supply for high bay lights shown, the front stage provides lightning protection 6KV withstand voltage requirements, which is mainly composed of F101, TR101, MOV101, MOV102, MOV103, RA101, RA102, RA103, MOV104, and the anti-surge circuit is composed of 6KV lightning protection. The protection function is mainly to protect the back-end circuit through the front-end input through MOV102, MOV103, RA101, and discharge to the ground to realize lightning protection.

[0015] The dimming part realizes output isolation standard >3.0mm through U302B, U302A, U401, and LED+, LED-

[0016] The rectification circuit performs rectification, including the first rectifier tube BD101 and the second capacitor C201 for voltage division and rectification, and R204, R205, R206, and C211 form a voltage stabilizing circuit to realize the power supply mode.

Abstract

The invention discloses a high shed lamp driving power supply, which comprises an anti-surge circuit for lightning protection, wherein the anti-surge circuit is electrically connected with a dimming circuit used for carrying out dimming and a rectifying circuit used for carrying out voltage dividing and rectifying. The invention provides an output and diming circuit which achieves a basic insulation and isolation effect and solves an interference problem and a safety problem at present.

Description

technical field [0001] The invention belongs to the field of electrical equipment, and in particular relates to an output and dimming circuit. Background technique [0002] At present, in the existing dimming technology, the output isolation and dimming cannot meet the latest safety standards and cannot meet the latest UL standards, and external interference can easily cause equipment interference. At present, our solution can realize the isolation effect of input and output to meet the latest UL standard, and the front stage can meet the lightning strike 6KV withstand voltage requirement. Contents of the invention [0003] In order to solve the above problems, the present invention provides an output and dimming circuit to achieve basic insulation and isolation effect, which solves the current interference and safety problems. [0004] An output and dimming circuit includes an anti-surge circuit for lightning protection, and the anti-surge circuit is electrically connect...
