Abstract
The utility model discloses a daylight simulator. The surrounding of a xenon lamp is provided with a reflecting bowl which is coated with an optical medium film, and a transmission glass is coated with multiple layers of optical medium films to eliminate the streak and the shadow generated on the xenon lamp. The daylight simulator can be used for matching color and evaluating the color fastness in the industry of the spinning, the military camouflage, the testing of cotton, the dyeing and finishing chemical fibre, etc.
Description
The invention belongs to electric lighting device
Color matching in industry such as light industry, chemical industry, satellite fax, camouflage, Cotton Inspection and dyeing and finishing, chemical fibre, evaluation dyefastness have been badly in need of having the daylight light source of a desirable standard since the work midium or long term.
Before the present invention made, simulating daytime was generally to adopt xenon lamp to do light source, saw through the multilayer filter glass and simulated, and its weak point is:
One, xenon lamp has very strong line spectrum radiation near the blue green end 470 μ m of spectrum, and this intense radiation wavestrip is narrow, and intensity is big, exceeds a times of all the other radiation, produces serious streak.
Two, uneven illumination is even fails to make full use of luminous energy, because negative and positive two utmost points of xenon lamp are a metal derby, make its illumination section present the shade of figure, generally eliminating this shade is to allow xenon lamp see through the thick diffusing glass of multilayer, therefore need more powerful xenon lamp, many luminous energy are wasted.And high-power xenon lamp produces a large amount of ozone, and is harmful, involves great expense.
Three, ultraviolet portion a little less than, because of light sees through after the multilayer diffusing glass, ultraviolet spectra is partly decayed too much, makes the ultraviolet portion of light source not reach the desirable level of standard white daylight.
The purpose of this invention is to provide does not a kind ofly have the width of cloth to penetrate streak, and illumination evenly can make full use of luminous energy, and is cheap, can reach the daylight simulator of desirable standard white daylight.
The present invention has figure
Figure is a daylight simulator schematic diagram, and (1) is xenon lamp among the figure, and (2) are double-paraboloid elliposoidal reflector, and (3) are the optical medium reflectance coating, and (4) are transmissive glass, and (5) are the reflectance coating and the transmission film of multilayer optical medium, and (6) are metal grill.
As one embodiment of the present of invention as shown in the figure, its main points are to add the reflector that a double-paraboloid Tuo Qiu Xing And is coated with the optical medium reflectance coating around xenon lamp.On transmissive glass, be coated with the transmission film and the reflectance coating of multilayer optical medium,, eliminate the streak width of cloth and penetrate with near its intense radiation of compacting xenon lamp wavelength 470 μ m.The metal grill that also adopts a kind of staggered choosing to add makes xenon source form the shadow region that numerous little spot light is eliminated xenon lamp, makes its illumination even.Plating multilayer optical medium transmission film and reflectance coating replaces the multilayer diffusing glass that in the past adopted on transmissive glass, makes the ultraviolet light part can reach the level of desirable daylight.
The present invention has the luminous energy of taking full advantage of compared with the prior art, uniform-illumination, cost is hanged down the advantages such as double, the daylight that simulates has reached the standard of ideal standard daylight, can be used in the measurement of the instruments such as light industry, weaving, satellite fax, camouflage, Cotton Inspection, Photometric Measurement, with the color matching of dyeing and finishing, chemical fibre industry, estimate the aspects such as dyefastness.
