Technical field
The utility model relates to the technical field of fluorescent lighting device in the fluorescent microscope, refers in particular to a kind ofly to adopt a plurality of LED as the fluorescent lighting device of light source.
Background technology
Fluorescent microscope has higher resolution and better contrast than simple microscope at present.In the existing technology, main high-pressure sodium lamp or the xenon lamp of adopting is as light source, exciting light arrives colour filter piece group by the cola illuminator, and (colour filter piece group is by exciting color filter, two to dichronic mirror, form by color filter), light source obtains required excitation spectrum through exciting color filter, reflect to dichronic mirror through two, arrive object plane through object lens, after being excited by the sample of fluorescent dyeing, produce spectrum greater than the light that is excited of exciting light, the light that is excited is through object lens, two to dichronic mirror, arrive eyepiece or imaging device by color filter (spectrum of wave band is cut off beyond the light that is excited).The sample that is dyeed by different dyes need need change different colour filter piece groups with the excitation of different wave length during observation.Because fluorescence is fainter, obtain enough strong fluoroscopic image, need very strong excitation source, so the employed light source of fluorescent microscope is generally Metal halogen lamps such as high-pressure sodium lamp, xenon lamp.This kind light source has enough brightness, but its power height, life-span are short, expensive, poor stability, heat radiation damage section by force, start needs preheating, shutdown to need cooling, has unfavorable factor such as explosion danger all to limit the range of application of fluorescent microscope.Development along with LED and illumination optical technology, its spectral range and energy have been enough to satisfy the requirement of fluorescent microscope excitation source, and have that power is low, the life-span is long, price is low, good stability, do not damage section, start does not need advantages such as preheating, shutdown need not cooled off, no explosion danger.Under the overall situation of current global energy-conserving and environment-protective, it is irresistible as the trend of fluorescent illumination source that LED replaces Metal halogen lamps such as high-pressure sodium lamp and xenon lamp.My department has produced single band LED fluorescent microscope, but a section is generally dyed multiple fluorescent dye is arranged, the exciting light that needs multiple different wave length, and present wide spectrum LED is expensive, single LEDs can only provide approximate single-range exciting light at a low price, and this just impels us to remove to develop a kind of multiband LED fluorescent microscope that adopts many many groups of single band LED coupling colour filter piece groups.

The LED fluorescent lighting device that the utility model provides has following advantage:
1, power is low, and the power of conventional high-tension mercury lamp or xenon lamp is generally 100W; Single LEDs light source, power is generally 3W;
2, the life-span long, the general life-span of conventional high-tension mercury lamp or xenon lamp is 300 hours; Single LEDs light source, the life-span was generally 5000 hours;
3, price is low, and conventional high-tension mercury lamp or xenon lamp are expensive; Single relative mercury lamp of LEDs light source or xenon lamp are cheap;
4, heat radiation is low, and the fluorescence section is mostly through fluorescent dyeing, and the cancellation of fluorescent dye fluorescence property has been accelerated in high-heating radiation.Conventional high-tension mercury lamp or xenon lamp heat radiation height, the damage section; The heat radiation of single LEDs light source is low, is difficult for section is produced infringement;
5, start does not need preheating, and conventional high-tension mercury lamp or xenon lamp have independent power supply box, and start needs preheating just can work; Single LEDs light source start need not preheating, but on-line operation;
6, shutdown need not cooled off, and after conventional high-tension mercury lamp or the xenon lamp shutdown, bulb just can open and use after need cooling off a period of time again, otherwise can significantly reduce the serviceable life of lamp; Single LEDs light source shutdown need not cooled off, and can open to reuse at once;
7, no explosion danger, conventional high-tension mercury lamp or xenon lamp such as improper use have the possibility of blast, and single LEDs light source does not have this risk;
8, energy-conserving and environment-protective, conventional high-tension mercury lamp or xenon lamp, power consumption height, life-span weak point, and use metal, the discarded improper serious environment pollution of aftertreatment; Single LEDs light source, power is low, and the life-span is long, and is difficult for environment is polluted.
