3、 Sub item of lighting system:

3.1 Light source system (German BFEPS)Or customized brand for Juwei：

Selection of Lamp: Made in GermanyBF original metal halide lamp4000W， Ensure the uniformity of radiation. adopt6The group lamp tube contains a reflector cover, and the light energy output of the lamp tube will gradually decay over time. In order to reduce the impact of light energy decay on the test and the uniformity of irradiationWith a requirement of 5%, this test chamber is designed with a lamp current control system to obtain a constant output of light energy.

Lamp power adjustment range50% -100% configuration of irradiation meter and lamp current control system, which can adjust the current of the attenuated lamp by increasing it.

Lamp quality assurance2000H effective irradiation, effective service life>3000H

3.2 Electrical Control:

3.2.1 Select imported microcomputer PID temperature controller for temperature control, and use imported electronic components for the rest.

Uniformity of irradiance:5% (at the surface of the sample). Temperature monitoring: Standard PT-100 Ω thin film temperature sensors are used to accurately control the surface temperature and back temperature of the sample during the testing process.

3.2.2 The test chamber is equipped with a time controller with a range of 0~9999H, which has the functions of accumulating time and power outage memory.

3.2.3 Safety protection devices:

If the lamp is on, once the door of the box is opened, the machine will automatically cut off the power supply to the lamp. And it automatically enters a balanced state for cooling to prevent harm to the human body. The safety door lock complies withIEC047-5-1 Safety Protection Requirements.

Over temperature protection inside the box: When the temperature inside the box exceedsAt 110 º C, the machine will automatically cut off the power supply to the lamp and heater, and enter a balanced cooling state.

3.2.4 Radiometer: Select a digital irradiance meter imported from Japan with replaceable sensors and equipped with a full wavelength sensor. The original factory has calibrated it, and it is recommended to calibrate it once a year.
