Technical field

The present invention relates to lamp, especially but not exclusively relate to the modularization lamp that in nondestructive testing, uses.

Background technology

Fluorescence is generally understood as and makes some material can absorb luminous energy and with the character of the wavelength radiation visible light longer than the light that is absorbed.Be not limited to any concrete theory, for what everybody accepted extensively be: the electronics in the fluorescent material obtains excitation by the optical energy irradiation of specific wavelength the time, and when electronics turns back to non-excitation or ground state from these material radiation luminous energy of long wavelength more.Special excitation and radiation wavelength are the specific fluorescent properties of materials.Except that other factors, the luminous apparent brightness of fluorescent material is also depended on the wavelength that material sends and is encouraged the intensity of the incident radiation of material.The fluorescent material that has its excitation peak at specific wavelength when the wavelength departure excitation peak of incident light, can send fast reduce a lot of luminous.When incident light does not have enough energy in the specific incentives scope, fluorescent material also will lose fluorescigenic ability.

The lamp that sends the radiation of activating fluorescent has been widely used in multiple purpose, include but not limited to forensic medical examination, admission control again, counterfeit money detect, pollute check, nondestructive testing, and equipment comprise leak detection in the system of liquid as air-conditioning and other.Light generally is in ultraviolet (UV) or visible indigo plant-purple scope, the somewhere activating fluorescent in visible range.Fluorescent material can specially provide.For example, some bank note have the fluorescence labeling that is embedded in the paper, and UV light is used to detect the mark of hiding under other situation.In another example, a kind of method that is used for detecting the leakage of air-conditioning system is to add in the cold-producing medium of system and the fluorescent dye that mixes with it by use, and the combination of cold-producing medium and dyestuff cycles through air-conditioning system.This method is at first advocated by assignee Spectronics Corporation of the present invention.In these leak detection systems, dyestuff cycles through system, finally oozes out at the source of leaks place.When being exposed to suitable light source such as ultraviolet (UV) light time, dyestuff fluoresces, thereby outstanding source of leaks.Under uviol lamp, only can also can be used in the stamp of admission again of entertainment event by the ink that fluorescence is seen.

Fluorescence may be the non-main character of wishing some materials of detection, measurement or observation.For example, many biomaterials comprise rodent hair and urine, all fluoresce naturally.Other example of use fluorescence comprises the detection of counterfeit money and other document.Many materials such as diamond can be by its natural fluorescence level and color verify or distinguish.

Many present fluorescence exciters send the light of long wave ultraviolet (UV-A) wave-length coverage from about 320nm to about 400nm, for example about 365nm; Perhaps medium wave ultraviolet (UV-B) scope from about 280nm to about 320nm, for example about 315nm; Perhaps shortwave ultraviolet (UV-C) scope, for example about 254nm; The perhaps visible purple/blue scope from about 400nm to about 480nm in the electromagnetic spectrum.

Regrettably, visible (comprising environment) light and fluorescence competition the causing personnel's that test attention from dyestuff.When other visible light intensity reduced, the visibility of fluorescence response increased, and makes fluorescence response not by other optical masking.It is particularly true when this has the shiny surface that reflects visible or surround lighting in system.Therefore, in the system that comprises UV response fluorescent material, the fluorescent material that uviol lamp can represent under the dark background under dark condition is luminous.When carrying out under complete black situation, the result of aforementioned process is strengthened usually; Yet, in test environment, can not realize usually complete black, the daylight outdoor air-conditioning that can not cut off or comprising dark workshop that may danger close when being in motion mechanical for example.

Similarly, fluorescent material also is used for nondestructive testing.For example, the fluorescent dye that combines with iron filings can be used for detecting defective such as stress breaks.The combination of iron filings and fluorescent dye attracted to fault location, and dyestuff sends visible light when being penetrated by suitable incident wavelength illumination.Very little defective is difficult to detect usually, and the little defective of even now may potentially cause very big danger.Therefore, any help all is useful when determining these defectives.

Existing uviol lamp has several weakness.Some concerns about existing uviol lamp are its cost, size and power consumption.For low-power consumption and cost, fluorescent lamp can be used for producing incident radiation.Yet fluorescent lamp produces low intensive incident ultra-violet radiation.For this reason, hope can make lamp locate near the defective place very much.When near work machinery and equipment, because the space is very nervous, this is difficult to usually.

Hand-held UV lamp is by Spectronics Corporation exploitation and at United States Patent (USP) 6,953, describes in 940, and this patent all is combined in this by reference.Light and the easy operating of this lamp.Yet, more consuming time when the small size irradiation that is produced by lamp makes check than large tracts of land.More specifically, in the room of bright illumination, the narrow width of unit makes the light from surrounding environment overwhelm fluorescence response sometimes, thereby makes detection difficult.The light of narrow width only has limited use in common test large tracts of land with the nondestructive testing field of finding defective.

Halide lamp generally is used in the nondestructive testing (NDT) at present, the light very hot and projection covering wide wavelength but halide lamp becomes.Cover for adapting to wide wavelength, use expensive filter to eliminate the suitable wavelength that unwanted optical wavelength and projection test need.Because filter absorbs or reverberation, they can heat the surrounding air that waits on every side.

Therefore, need a kind of compactness, send ultraviolet (the comprising blue light wavelength) light of active strength and do not produce the lamp holder of a large amount of heats.
