Why did the ceiling light in the bathroom dim after a while

Inevitable. 1. All bulbs have the problem of attenuation. For example, LEDs attenuate by about 5% per year; Fluorescent lamps are aging and blackening, and the luminescence will be reduced; incandescent lamps, filament evaporation, and so on.

2. As a lamp, there is also attenuation, such as dust, oxidation of various copper sheets, resulting in contact resistance, acrylic lampshade yellowing after aging, and light transmittance drops from 90% to 60%.

3. The background environment changes, and the light absorption is high and the reflection is less. The ceiling, walls, floors, and interior furnishings of the bathroom may become old and dirty over time, and the reflectivity of the surface will decrease.

Hello dear, it is inevitable that the ceiling of the bathroom will be darkened. Inevitable. 1. All bulbs have the problem of attenuation.

For example, LEDs attenuate by about 5% per year; Fluorescent lamps are aging and blackening, and the luminescence will drop back to low; White incandescent lamp, filament evaporation, and so on. 2. As a lamp, there is also attenuation, such as the lack of stool dust, the oxidation of various copper sheets, resulting in contact resistance, the acrylic sensitive lampshade yellows after aging, and the light transmittance drops from 90% to 60%. 3. The background environment changes, and the light absorption is high and the reflection is less.

The ceiling, walls, floors, and interior furnishings of the bathroom may become old and dirty over time, and the reflectivity of the surface will be reduced. I hope my answer is helpful to you and I wish you a happy life!

If it's all bright, it's light decay. Lamps and lanterns have light attenuation, but the light attenuation of good quality is not very obvious, and the light attenuation of poor quality is more obvious. If it continues to darken after a period of use, it is recommended to replace it.
