Description

Technical Field

[0001] The utility model relates to the technical field of film testing equipment, in particular to a solar film optical performance detection device. Background Art

[0002] Solar film is also called heat-insulating film. In modern solar film production technology, aluminum, gold, copper, silver and other metals are often made into multi-layer dense high-insulation metal film layers through vacuum spraying or magnetron sputtering technology. The free electrons in the outer shell of metal materials are generally not bound by the nucleus. When irradiated by light waves, the electric field of the light waves causes the free electrons to absorb the energy of the light and produce oscillations with the same frequency as the light. This oscillation emits light with the same frequency as the original light, which is called light reflection. The higher the conductivity of the metal, the shallower the penetration depth and the higher the reflectivity. These metal layers will selectively reflect back various heat energy sources in the sun, including infrared, ultraviolet and visible light heat energy, and then release them outward for the second time after the color on the film absorbs the solar thermal radiation, and take away part of the heat with the outdoor air flow, thereby effectively playing a role in heat insulation.

[0003] The principle of testing the optical performance of solar films is based on simulating different bands in the solar spectrum. Ultraviolet light, visible light and infrared light sources are used to illuminate the transparent material to be tested. The sensor detects the incident light intensity of the three light sources and the light intensity after passing through the transparent material to be tested. The ratio of the transmitted light intensity to the incident light intensity is the transmittance. The visible light transmittance indicates the ratio of the visible light flux passing through the solar film to the visible light flux projected on its surface; the infrared blocking rate indicates the ratio of all solar infrared rays blocked on the outside of the solar film to the total infrared energy irradiated on the surface of the object. The lower the infrared transmittance, the less heat energy will penetrate the car window glass; the ultraviolet blocking rate: indicates the percentage of the ultraviolet light intensity passing through the solar film to the incident light intensity within the ultraviolet spectrum.

[0004] The visible light transmittance, ultraviolet blocking rate and infrared blocking rate of solar film are important standards for measuring the quality of solar film products. Solar film testers in the existing technology usually adopt the method of sampling and then testing the samples for testing, which causes damage to the product and cannot conduct real-time and continuous testing of large sections of solar film to be tested, increasing the testing cost.
