Carbon arc lamp aging test

The carbon arc lamp aging test is one of the test methods that simulates the aging of light. There are two types of carbon arc lamp aging tests: one is a closed carbon arc lamp, and the other is a sunlight-type carbon arc lamp. The former is initially used for the light resistance test of textiles, and the latter is used for the light resistance test of layers.
The luminous body of a closed carbon arc lamp is a group of carbon rods. The spectral energy distribution of the arc light emitted by the current passing through the carbon rods is quite different from the spectral energy distribution of natural light. There is neither the segment-wave ultraviolet radiation of natural light nor the high-intensity energy of sunlight between 400-800nm.
The matching of the spectral energy distribution of solar carbon arc lamps and sunlight has improved, but the spectral energy distribution between the two is still very different between 50-350nm.
Zhongke Testing Environmental Reliability Experiment Center has various climate environment simulation test equipment and has carbon arc lamp aging test capabilities. It provides professional carbon arc lamp aging test services for various auto parts products, electronic products, some coatings and rubber parts, etc.

The main products that require carbon arc lamp aging tests are:
Automobile accessories products: Automotive plastic parts (external rearview mirror assembly, car battery connector, front and center door interior panel assembly, car seat belt webbing, power adapter shell, steering wheel multi-function switch, car radar, car carpet, car light switch, clutch oil tank assembly, oil tank assembly car, etc.);
Other products: outdoor equipment, electronic products, some coatings and rubber parts.
