Xenon lamps simulate irradiance manipulation in UV aging test chambers

The output of all types of xenon LED lamps is an attenuation coefficient
over time.

Xenon lamp aging test chamber applies an opinion feedback control loop automatic control system for carrying out compensation
.

With the system software, operators can pre-position irradiance scales, while the irradiance controller in the inspection chamber makes precise measurements
of the light source.

When the LED tube is embrittlement caused by the output attenuation coefficient, the system software will carry out fully automatic compensation
according to the output power of the xenon lamp.

Basically, the compressive strength of the light source can be monitored in random parts of the xenon lamp spectrometer, but the general application is only a good number of bands
.

Irradiance manipulation is generally carried out in spectrometer areas where raw materials are more sensitive (e.
g.
, areas where interpretation is expected
).

In addition, the irradiance reference point also changes
depending on the manufacturing industry and application.

The 340nm reference point is widely used in accelerated high and low temperature tests, and there are risk factors
in the medium and short wave ultraviolet light areas for the high and low temperature test of outdoor performance products.

The 340nm manipulation regulation includes an armed UV controller equipped with a filtering device, which only allows 340nm as the management center of the narrow band basis
.

In general, this is an ideal reference point
for architectural coatings, plastics, roofing waterproofing materials, etc.

The common irradiance reference point of zui is 0.
35 or 0.
55W/㎡/nm340nm
.

The 420nm reference point is generally used for the light stability test
of the raw material used in the supporting facilities of the glass window filtration device.

For the operation of 420nm, it is stipulated that the ultraviolet light controller is equipped with a filter, which only allows the ultraviolet narrow band basis
of 420nm as the management center.

The system typically targets raw materials that are destroyed by long-wave ultraviolet and visible light, such as dyes and melanin in textiles, paper patterns and printing inks
.

The common irradiance setting point for room simulation is 1.
10W/㎡/nm420nm
.

Tablet and rotating drum xenon lamp aging test chambers are generally equipped with 340nm or 420nm narrowband irradiance automatic control system
.

In general, tablet and rotating drum xenon lamp aging test chambers contain, equally, feedback control loop irradiance automatic control system
.

It is proposed to replace the LED lamp on time to reduce the harm of LED tube embrittlement
.

Depending on the application of the controller that manipulates the irradiance at 340nm or 420nm, the amount of spectrometer changes in special regions is further reduced
