How to do aging testing for UVLED lights?

UVLED lamp aging test mode

1. Lighting stage

Imitate the daylight exposure length (usually between 0.35W/m2 and 1.35W/m2, with a summer noon sunlight intensity of about 0.55W/m2) and experimental temperature (50℃~85℃) in natural environments to simulate various application environments of the product and meet the testing requirements of different regions and professions.

2. Condensation stage

Imitate the phenomenon of fogging on the surface of the sample at night, turn off the fluorescent ultraviolet lamp (in a dark state) during the condensation stage, and only control the experimental temperature (40-60℃). The humidity on the surface of the sample should be 95-100% RH.

3. Spray stage

Simulate the process of rain by continuously spraying water onto the surface of the sample. Because the experimental conditions for artificial ultraviolet accelerated aging are much stricter than those in natural environments, it can simulate and reproduce aging damage that only occurs in natural environments for several years within a few days or weeks.

The experimental equipment uses fluorescent ultraviolet lamps as the light source to simulate sunlight ultraviolet rays, and can also simulate the effects of dew drops and rainwater through condensation or spraying. The samples can simulate damage that may occur in the wild for months or even years, and the damage results that may take months or years to occur in the wild, after being tested for dozens of hours or even days in a simulated solar ultraviolet environment in a laboratory UV aging test chamber. Reproduce the aging conditions of the product after UV aging, including fading, discoloration, decreased brightness, powdering, cracking, blurriness, brittleness, decreased strength, and oxidation.

The reliable data provided by the UV aging test can make accurate correlation guesses about the weather resistance (anti-aging) of the product, and help to select and optimize the information and formula.

1. It is not easy to turn on the machine when the UV light is on. UV ultraviolet light is emitted as ultraviolet light. We should prevent turning on the machine after turning on the light during use to reduce the radiation of ultraviolet light on the human body.
2. Ensure sufficient water in the water tank (it is recommended to use the external active water addition function). When conducting spray testing, the water consumption is relatively high. To prevent the phenomenon of no water halfway through the test, it is common to connect the external active water addition function.
3. If the machine has been transferred or moved locally, it needs to be leveled after confirming its location.
4. The machine needs to clean the water tank and humidification tank every month of use. In repeated experiments, the water tank in the machine easily forms scale, and it needs to be cleaned once a month of use to reduce the machine's failure rate and increase its lifespan.
