Description

A kind of high accuracy raw silk appearance detection lamp electro-optical device

Technical field

The utility model relates to a kind of raw silk checkout equipment, particularly a kind of high accuracy raw silk appearance detection lamp electro-optical device.

Background technology

Traditional raw silk appearance detection lamp electro-optical device has two kinds, and one is bucket type light harvesting lampshade, and one is plane combination lampshade, and light source is fluorescent lamp.GB/T1798-2008 " raw silk test method " 4.2.2 money regulation, the soft silk that irradiates is equably on the end face of (silk cylinder) at a certain distance for the light of outward appearance examination criteria lighting fixture, and the illumination of end face is 450 ~ 500lx.Above-mentioned lighting fixture in actual use, owing to being subject to new and old, the arrangement mode of spread of voltage, fluorescent tube, the impact of colour temperature difference, silk on check-out console is difficult to end face illumination to be controlled within the scope of 450～500lx, survey 4 Jia Si class enterprise raw silk appearance detection lamp electro-optical device illumination, uneven illumination is even is universal phenomenon, some illumination extreme difference exceedes 100lx, and some illumination is generally lower than 450 lx or generally higher than 500lx.Simultaneously fluorescent light also exist start slow, have stroboscopic, lamp tube ends to have between blackhead, fluorescent tube to have the problems such as aberration.Problem on these equipment easily causes inspector to judge by accident in the time that outward appearance detects, and affects testing result accuracy.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of and guarantee that lighting fixture light impinges upon silk upper uniform-illumination is stablized, meet the standard-required of 450～500lx scope, energy-saving and environmental protection, long service life, cost of manufacture is low, high accuracy raw silk appearance detection lamp electro-optical device convenient for installation and maintenance.The purpose of this utility model realizes by following technical proposals: the utility model comprises light source, lampshade, it is characterized in that: light source is the hard lamp bar of the LED of 5500K colour temperature light source, hard lamp strip adoption high thermal conductivity aluminum matrix pcb board, LED lamp pearl paster is evenly installed on every hard lamp bar, lampshade is rectangle, comprise lampshade frame, lampshade substrate and lampshade panel, lampshade substrate is a whole sheet of planar plate, the hard lamp bar of LED is arranged in parallel and is arranged on lampshade substrate, lamp bar arrangement mode is taked to be arranged in parallel to close arrangement mode from center by rare, intermediate lamp stripe pitch is 0.8-1.2 times of two cowl lamp stripe pitch, middle 4 lamp bars are one group of circuit, be connected on a 12V dc source, two cowl lamp bars are another group circuit, be connected on another 12V dc source, lampshade panel is true qualities ground glass panel, itself and substrate distance 13-17cm.

Between the LED lamp pearl paster of installing on the hard lamp bar of said every LED light source, square is 13.7-14.1 cm.

8 to 12 the hard lamp bars of LED are installed on described lampshade substrate.

The utility model selects the hard lamp bar of the LED of 5500K colour temperature as light source, and brightness is high, each lamp pearly-lustre flux 35LM, and the actual illumination of lamp bar is equivalent to 150W incandescent lamp, greatly saves the usage quantity of traditional tube; Energy saving, lamp body power 17.28W/m, power consumption only has 10% of conventional lights; Long service life, the light source design life-span more than 50000 hours, can be used more than 10 years, has avoided traditional tube to need the fatigued of often replacing; Caloric value is little, lamp strip adoption high thermal conductivity aluminum matrix pcb board, and caloric value is low, has avoided lamp bar to continue to use long security risk; Installation and maintenance are simple, and lamp bar is whole piece integrated circuit, only need be to the installation and maintenance of whole lamp bar; Start soon, without stroboscopic, avoided traditional tube to start slow, have stroboscopic, very easily cause the asthenopic phenomenon of people; Whole lamp bar lamp pearl paster luminous flux is consistent, luminous uniform and stable, has avoided conventional light source long rear lamp tube ends service time to occur that blackhead affects illuminance uniformity; Due to the unified lamp bar that adopts 5500K colour temperature, light source color and luster is consistent, has avoided the aberration between conventional fluorescent pipe manufacturer difference, fluorescent tube that service time, difference was brought to cause that uneven illumination is even.Lampshade substrate adopts a whole sheet of planar plate, and no longer grouping overcomes the shade dark space that each group of material isolation produces, and makes light source even.The utility model adopts the arrangement mode of LED light source and science, uniform-illumination is stable, illuminations actually measured between 460～500lx, narrow down to ± 40 lx of illumination fluctuation, can reach the raw silk standard-required of 450 ~ 500lx completely, and conventional light source differences of illumination intensities is difficult to reach standard gauge provisioning request.The utility model energy saving, five type lampshades use 10 of LED lamp bars, and total power consumption is 172.8W, and traditional lampshade needs at least 12 40W fluorescent tubes, at least 480W of total power consumption, LED light source power consumption is only 1/3rd of conventional light source.The utility model long service life, cost performance is high, be easy to promote, LED light source can reach 10 years service life, conventional light source 3-10 in service life month, five type lampshades used LED lamp bar than traditional tube few 2, and single price is only 2 times of traditional tube, be the more than 10 times of traditional tube service life, and cost advantage is obvious.From above-mentioned situation, the purpose of this utility model can with realize.

The utility model using method, detect on the check-out console under lighting fixture in outward appearance, the arrangement mode being listed as according to 4 rows 5 places 60 raw silk, turn on lights electro-optical device general supply, whether inspecting lamp bar is bright neat, and by the parallel silk that is placed on of photosensitive head of illumination photometer (the safe bodyguard in Taiwan), on end face, test silk is end face illumination, be uniformly distributed illumination test point, on check-out console, surrounding and center all will be tested.If test result illumination, within the scope of 450～500lx, can start outward appearance testing, if on the weak side partially strong, availablely illumination is finely tuned with 12V dc source voltage device, until reach standard-required.
