Light intensity control method of combined led street lamp

Abstract

The invention provides an illumination intensity control method of a combined LED street lamp. The LED modules in the combined LED street lamp are turned on selectively through illumination intensity detection and according to the amplitude of the illumination intensity; due to the fact that standby LED modules are arranged, even if one LED module breaks down and cannot be turned on, one standby LED module can be started to replace the broken LED module, and the illumination intensity of the LED street lamp is guaranteed. Furthermore, an LED module mode instead of regulating voltage at the two ends of the LED street lamp is adopted, and therefore the fault rate is lower; even if some faults exist, the street lamp can run continuously, and the stability is very high; if the illumination intensity of the LED street lamp cannot be guaranteed, a street lamp management department can be informed, and the street lamp management department can conduct maintenance conveniently.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a method for controlling the light intensity of a combined LED street lamp. Background technique [0002] The LED street lamps in the prior art are generally installed on the light poles on the roadside, and generally include two parts: an LED light source module and a power supply. The light sensor senses the intensity of external light, so as to switch the street lamp according to the time period, but the intensity of the light of the street lamp itself cannot be automatically controlled. [0003] In the prior art, there is also a street lamp control method that can control the light intensity of the street lamp itself, but this control method is to control the light intensity by adjusting the voltage of the street lamp. This control method is easy to cause damage to the LED street lamp, resulting in street lamps The failure rate is high. Contents of the invention [0004...

Problems solved by technology

[0002] The LED street lamps in the prior art are generally installed on the light poles on the roadside, and generally include two parts: an LED light source module and a power supply. The light sensor senses the light intensity of the outside world, so as to switch on and off the street light according to the time period, but the light intensity of the street light itself cannot be automatically controlled.

[0003] In the prior art, there is also a street lamp control method that can control the light intensity of the street lamp itself, but this control method is to control the light intensity by adjusting the voltage of the street lamp. This control method is easy to cause damage to the LED street lamp, resulting in street lamps high failure rate
