Flashing light can easily evoke horrific images especially when you are going to cook in your kitchen. The flickering kitchen lighting not only makes you feel fear but also makes the sight unclear. Calling in the pros will take a lot of money so maybe you can try to check the fixture by yourself. We are going to show you the most common electrical issues and how to fix them by yourself.

 

 

 

A large black area of both ends 

 

There are three reasons for this phenomenon. One is a clear boundary towards the filament at a distance from the filament; A fading black ring that extends far toward the middle of the tube, as if something is thrown from the filament and lands on the tube wall.

 

This kind of projectile black spot is estimated to be the result of positive ion bombardment sputtering caused by the high voltage starting, indicating that the preheating is not good, the starting voltage is too high.

 

The other is that the filament bracket begins to black at a point near the tube wall, gradually extending along with the filament bracket and spreading outward, then turning yellow in large areas, and finally becoming black in large areas. This is most obvious when the inductive ballast lights the inferior T8 and T12 lamps.

 

This black spot is more likely to be caused by heat evaporation of the filament, due to the poor quality.

 

In other cases, a section of tube wall surrounding the filament gradually darkens, forming a black spot, and finally becoming completely opaque a few centimeters long. 

 

No matter which way the lamp starts blackening, it means that the kitchen lighting is near the end of its life.

 

Solution

 

As for this phenomenon, the only solution is to replace the kitchen light with a new one.

 

Steps of replacing lamps

 

• Turn off the power.

 

• Catch the light bulb and turn it counterclockwise until it loosens.

 

• Fetch it out and fix the new one on the fixture.

 

Caution

 

Do not pull the light bulb directly, you had better first turn the lamp tube half circle so that its two tips and card groove overlap and then take out.

 

Matching trouble

 

The LED lamp bead does not match the LED drive power supply. If the bead chip is not full power, it will cause light source stroboscope. If the current is too high, the lamp will turn on and off. If the current is too high, the gold or copper wire inside the lamp will be burned off, resulting in the lamp not shining.

 

Solution

 

Just replace it with another good power supply.

 

Over-temperature protection function

 

If the drive power supply has the function of over-temperature protection, and the material heat dissipation performance of the lamp can not meet the requirements, the drive over temperature protection will start to work and there will be a flashing phenomenon. For example, 30W lamps are equipped with 20W projection lamp shell.
