What is lumen depreciation？

It refers to the phenomenon that the luminous flux of a light source gradually decreases over time during its use. This is a natural process of light source aging, which is influenced by multiple factors such as temperature, humidity, and current stability. Light attenuation is one of the important parameters for evaluating the performance and lifespan of light sources.

The influencing factors of light attenuation include:

Light source type: Different types of light sources have different light attenuation characteristics. For example, the light attenuation of leds is usually low.

Heat dissipation system: If the heat dissipation system is well done, usually after 1000 hours, there is no noticeable decline in brightness

The usage environment: Environmental factors such as temperature and humidity can also affect the speed of light attenuation.

Working conditions: The stability of the current, the working duration of the light source, and other factors will all affect light attenuation.

To reduce the impact of light attenuation, the following measures can be taken:

Choose high-quality light sources: Select light sources with low light attenuation and long lifespan.

Optimize the usage environment: Maintain an appropriate temperature and humidity to reduce the impact of environmental factors on the light source.

Regular maintenance: Regularly clean and maintain the light source to keep it in good working condition.
