Shanghai Lin frequency introduction of ultraviolet light weatherproof test box lamp
The ultraviolet light weatherproof test chamber uses a fluorescent ultraviolet light as a light source to simulate the weathering resistance of the material by simulating the ultraviolet radiation and condensation in the natural sunlight to obtain the weather resistance of the material. Today, Xiaobian mainly explains the lamp that simulates natural sunlight.
UV light weatherproof test box lamp adopts American Q-LAB, a global supplier of material durability test products. Founded in 1956, the company designs and manufactures standard test substrates and aging and light stability tests. The total length of the lamp is 1200mm. Each device needs eight lamps combined, the power is 40W, and the effective service life is about 500 hours. There are two kinds of UV lamps: UVB-313 and UVA-340. The main difference is that the wavelength is different. The UVB-313 lamp has a wavelength of 280-315 nm. Its luminescence energy is mainly concentrated at the wavelength of 313 nm. The UVA-340 lamp has a wavelength range of 315 to 400 nm, and its luminescence spectrum energy is mainly concentrated at a wavelength of 340 nm.
When the UV light weatherproof test box lamp is still lit after the life is reached, can it continue to test? In fact, the life of the lamp is not unusable, but the ultraviolet light intensity generated by the same ability input of the lamp is not enough, that is, ultraviolet light. The output is low in efficiency, resulting in energy loss.
