Not long ago, I saw some netizens asking on the Internet: Why does my ceiling light flash after turning on the light, and flash for a while before going out after turning off the light! Regarding this question, I found that many netizens are asking. The method and principle we give is: replace what is broken!
So, we should probably check from the following aspects to find out where it is broken.
First of all, we have to know that the reason why the ceiling light can emit light is due to the light source, not the lampshade itself (no joke, some users really think that the ceiling is a whole light source). Most of the common ceiling lights nowadays are LED or energy-saving lamps or fluorescent lamps. However, due to their shape, the light source may be a bulb, energy-saving lamp tube, or O-type or H-type lamp tube.
Why do we screw out the light source separately? Because basically only these types of ceiling lights will have a flickering light after turning on and off the power after a problem occurs, and the reason is mostly due to the discharge of the energy storage electronic components in the driver.
When we find that the brightness of the ceiling lamp at home suddenly decreases, if this lamp uses LED light source or fluorescent energy-saving lamp as the light source, and can light up in groups, it is mostly because one or two groups of the digital segment switch are broken. At this time, we can replace the digital segment switch.
If it is a ceiling lamp composed of O-type fluorescent lamp or H-type fluorescent lamp, and it cannot be dimmed, it should be that the ballast of a fluorescent lamp is damaged or the lamp tube is aging. When repairing, you should also check whether the ballast input and output ends on the unlit lamp are connected to the wiring to see if there is a virtual connection.
If the LED ceiling lamp composed of strip or 0-type patches suddenly decreases in brightness, there is generally a digital segment switch to control the drivers of each group of patch LED lamps separately. You can use a 220v bulb to connect the group of lines that the digital segment switch does not light up, turn on the power, the bulb lights up, and the segment switch is normal, otherwise the segment switch is broken.
Generally speaking, for LED lamps composed of patches like this, the power of each group of drivers is mostly the same. You can unplug the plug on the driver that can light up the lamp, and plug it into the socket of the LED patch that is not lit. After turning on the power, the lamp beads on the patch light up normally, which means that the driver that did not light up before is broken. If the LED patch lamp beads cannot light up, then the lamp beads on the LED patch are broken.
Of course, we may not have so much time to check and repair lamps, or even have special tools. Then the easiest way is to find a professional to repair it. If it doesn't work, just change it.
Lighting design is not about choosing a lamp, it is a job that combines both technical and artistic aspects. If you really don't have the time and professionalism to DIY lighting design, you might as well replace it with our Luxsky light ceiling lamp, which has a five-year warranty and reliable quality.
