What is the flicker of LED lamps and how to solve it?
Flicker is a flicker that occurs due to frequency. The phenomenon of light source stroboscopic means that the light emitted by the light source changes rapidly and repeatedly with time, which makes the light source beating and unstable. Studies have shown that light source stroboscopic light is closely related to neurological diseases such as migraine, headache, autism, visual fatigue and discomfort. In serious cases, it will cause delusions to the human eye and cause accidents.
Causes of flickering:
If there is no suitable electronic circuit for driving the lamp, such as ballast, driver or power supply, the light source will produce stroboscopic. The greater the fluctuation of the output luminous flux, the more serious the stroboscopic.
As for LED lights, from the light-emitting theory, LED lights themselves will not produce stroboscopic, and whether there is stroboscopic or not depends on the LED drive circuit. Due to the wide variety of drivers, the flicker performance of each LED product is also different. In particular, some manufacturers use relatively simple driver chips in order to save costs, and there will be a large stroboscopic problem.
In addition, many LED lights use PCB boards with lamp beads soldered, which has high requirements on the driving power supply. Any minor errors such as hardware quality problems may cause dead beads, stroboscopic, and uneven light color. , or even no light at all.
flicker solution:
1. The LED lamp bead does not match the LED drive power supply. If the lamp bead chip is not of sufficient power, it will cause the light source to flicker. If the current is too high, the lamp bead will turn on and off if it can't bear it. Serious phenomenon will cause the built-in gold of the lamp bead. The wire or copper wire is blown, causing the lamp bead to not light up.
2. If the drive power supply is broken, just replace a drive power supply.
