Abstract
The utility model relates to a strong-light view-box with cold light source used in the industrial X-ray observation, designed in order to solve the problem that the brightness of the existing view-box is low, which easily causes the mistaken judgment. The structure is: a light source is installed in the box body; the light source confronts the glass window. The improvement is: the light source is the hid gas discharge lamp; the electric circuit of the hid gas discharge lamp has a switching power supply and a high-voltage converter. The brightness of the utility model can be 3200 lumen degrees, three times of the brightness of traditional view-boxes; the device can clearly observe minor flaws on X-rays with the largest 5.5 darkness D of the negative. The utility model is of high brightness, good observation effects and long service life; and the device is suitable for the accurate X-ray observation in the detection with no damage.
Description
Technical field
The utility model relates to a kind of industrial X-ray sheet observation device, specifically a kind of cold light source high light viewbox.
Background technology
Viewbox is that the X-ray sheet of clapping in the nondestructive examination work is observed, to judge the whether qualified observation apparatus such as weld seam on the industrial products.The quality of its performance concerns the correctness to the observation of X-ray sheet.Common viewbox is that the lamp source is installed in casing, and the glass window on the casing is aimed in the lamp source.Used lamp source is a kind of to be incandescent lamp bulb, and a kind of is fluorescent tube.There is the high problem of heating in incandescent lamp bulb, directly influences the serviceable life of filament, and frequent replacing bulb, makes troubles also for the use of viewbox.The brightness of fluorescent tube is limited, and the photographic density of the X-ray sheet of the national X ray examination criteria regulation of distance still has certain gap, and promptly bigger to photographic density X-ray sheet can not be seen its trickle defective clearly, and the result causes erroneous judgement disconnected easily, brings hidden danger to product quality.
The utility model content
The purpose of this utility model just provides a kind of cold light source high light viewbox that can clearly observe various X-ray sheets.
The utility model is achieved in that a kind of cold light source high light viewbox, the lamp source is installed in casing, glass window is aimed in the lamp source, and institute's improvements are that the lamp source is the hid gas-discharge lamp, are connected to Switching Power Supply and high tension transformer in the electric loop of hid gas-discharge lamp.
Hid gas-discharge lamp in this device claims " xenon lamp " again, is a kind of high-intensity gas discharge lamp, is to utilize positive and negative electrode to stimulate xenon and rare metal chemical reaction and luminous.A ballotini of filling xenon and a little rare metal is arranged in the fluorescent tube of xenon lamp, hit xenon molecule alive, make it free, just can send high light with heavy current.The mobility of xenon molecule can be active all the more along with the growth of service time, so hid gas discharge lantern festival is used brighter and brighter.For making the normal luminous work of hid gas-discharge lamp, in its electric loop, be connected to Switching Power Supply and high tension transformer.Switching Power Supply is in order to be transformed into the 220V alternating voltage stable 12V DC voltage, high tension transformer is that 12V DC voltage moment is boosted to 23KV, could stimulate the xenon molecule free like this, send high light, make the hid gas-discharge lamp stablize luminous constantly work.
Brightness of the present utility model can reach 3200 lumen degree, is three times of traditional viewbox brightness, can clearly observe photographic density D and be trickle defective on 5.5 the X-ray sheet to the maximum.Because be to adopt the cold light source electro photoluminescence luminous, so the power consumptive province does not produce high temperature, not fragile, can reach more than 2500 hours serviceable life.The utility model brightness height, working stability, observation effect is good, is applicable in the Non-Destructive Testing work the accurate observation to various X-ray sheets, to improving and guaranteeing product quality, has great importance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a circuit structure block diagram of the present utility model.
Embodiment
Show that as Fig. 1 the utility model is two glass windows 3 that are provided with on casing 1 that one is long and the other is short, be separately installed with hid gas-discharge lamp 2 over against two glass windows at box inside.Switch 4 and gear pushbutton switch 5 also are housed on the panel of casing 1.Its using method is identical with the using method of traditional viewbox.
Among Fig. 2, in the electric loop of hid gas-discharge lamp 2, be connected to Switching Power Supply 6 and high tension transformer 7.Switching Power Supply 6 is transformed into stable 12V DC voltage with the 220V alternating voltage, and high tension transformer 7 boosts to 23000V with 12V DC voltage moment, supplies with hid gas-discharge lamp 2, makes its luminous work.
