Abstract

A heat dissipation control system of an LED lamp is composed of a power supply module, a constant current source module, an LED module, a radiator, a fan and a control system of the fan. According to the heat dissipation control system of the LED lamp, a system device is formed by combining active cooling of the fan with natural convection cooling of air and through an intelligent-control heat dissipation assembly; after the lamp is energized, the fan is controlled by the temperature control module; when the temperature control module detects that the temperature of the radiator exceeds a set standard, the fan starts to work, air circulation is accelerated, and the temperature of the radiator is lowered; and when the temperature control module detects that the temperature of the radiator is lower than the set standard, the fan stops working. In this way, the service life of the fan can be greatly prolonged, and electric energy is saved.

Description

technical field [0001] The invention belongs to the technical field of LED lighting, and in particular relates to a heat dissipation control system of an LED lamp. Background technique [0002] At present, LED lighting applications are increasingly widespread, but its photoelectric conversion rate is still only about 30%, and the remaining 70% of electrical energy is still consumed in the form of heat. However, the light decay of LED is directly affected by temperature, so solving the heat dissipation problem of LED lamps is an important link in the application of LED lighting. Therefore, in order to solve the heat dissipation problem of high-power LED lighting fixtures, some enterprises usually adopt fans to actively dissipate heat to reduce the area of ​​the radiator and the volume of the lamps. The life span is seriously out of balance, and it will also cause unnecessary power consumption when the climate changes. Contents of the invention [0003] The purpose of the ...
