Is well known that graphite and lamp and xenon lamp spectral distribution of a wide range of UV emission, harmful effects on the human body stronger. Cheap Garden Flags Wholesale In the course of such light to produce ozone, Custom Car Mirror Flags ozone in a small amount of good for people, is a serious health
Strong infrared light source to the human eye burning, hot summer in the high-power xenon lamp inside the device or di fine light make the inside temperature rose to unbearable level, coupled with the discharge of graphite and light also produce nitrogen oxides and volatile trunk dust, these will affect human health and pollution to the environment. Custom Car Mirror Flags
(d) operating economy. Plate require the replacement of the light source, site cleaning and other tedious day-to-day operations, but also requires a certain technology, it can be said that the use of light, is an annoying and difficult to tea. Its running cost is also a very important issue, and therefore the lamp life (time), exposure time, labor costs, depreciation of the lamp to conduct a comprehensive cost accounting.
They are able to instantly start, Yard Flags And Banners high switching frequency of resistance, long life, Custom Car Mirror Flags rated the brightness of the light source can achieve in a short time after boot, and generally welcomed by plate manufacturers.
(e) the reproduction of images. Reproduction of the image refers to the version of film faithfully reproduce the image on the bottom plate, and then one from the light source, copy, Car Mirror Flags imaging and other factors determined. The reproduction of the image by the degree of seal of the bottom plate and the photosensitive film and optical direct the.
(f) spectral energy stability. Better the stability of the light source of the radiation spectral energy distribution law. In the the the the within the time limit of the effective use of, spectral Laws of energy distribution should be no an obvious change.
(g) light thermal radiation is small. Ensure that the light source has a sufficient luminous intensity or brightness of the premise, the thermal radiation of the light source should be as small as possible. O'clock using high-power a strong light source, you must right the lamp to to take forced cooling (air-cooled, water-cooled), and and other measures, the and adopt of other measures, so that the the the the exposure of surface temperature of the photosensitive material to control in the the
(h) the luminous intensity is uniform. Custom Car Mirror Flags The irradiation side of the the light source the luminous intensity should, as far as possible, evenly. The exposure device shall be designed to ensure that the exposed surface of the photosensitive material-point lighting is poor does not exceed 15%. Decorative Garden Flags Wholesale
i. light environment adaptability. The light source should have a strong ability to adapt to the environment, under various changes of temperature, air flow, voltage, and can work properly.
Of course, the in the the in the actual production,, To select the one kinds able to fully meet the light source of the the above-mentioned the requirements of it is unrealistic to. The purpose of the selection principle, only plate operators choose to use a plate light, should take into account the quality of light exposure on the photosensitive material, a definite purpose.
