Abstract
A microscope bottom lighting source formed by LED back light plate is featured as setting light intensification film on diffusion film in LED back light plate for obtaining uniform-lighting with brightness and color both being able to be adjusted.
Description
Technical field
The present invention relates to (descending) lighting source at the bottom of a kind of microscope that constitutes by the LED-backlit plate, belong to (descend) lighting source manufacturing field at the bottom of the microscope.
Background technology
(descend) lighting source at the bottom of the existing microscope, on structural design, adopt incandescent lamp, be the illuminating source that single or multiple LED (light emitting diode) constitute, the rayed that these light sources send is on frosted glass, to scheme to form even illumination light.Its weak point: 1, frosted glass is not a good cosine radiative material, can not form well behaved even light, and still existence and the relative hot spot of incandescent lamp or LED (light emitting diode) position directly influence microscopical observing effect.2, because such structure, the above gap of 30mm is arranged between light source and the frosted glass, making has the microscopical base thickness of end illumination all more than 50mm at present, and this is waste material not only, has also raised microscopical focusing position, is not easy to operation.3, incandescent lamp the time will produce bigger heat in work, and the temperature that can cause being equipped with the Microscope base of incandescent lighting rises, and this not only can influence operator's use, also can influence the observation to the responsive to temperature object simultaneously.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of light intensity evenly and the microscope bottom illuminating light source of thin thickness.
Design proposal: in order to realize above-mentioned purpose of design.1, with the LED-backlit plate as microscope at the bottom of (descending) lighting source, be one of feature of the present invention.By diffuser plate light intensity is evenly distributed because the LED-backlit plate self has the illumination that light source and light source produce, therefore can satisfy the needs in (descending) irradiation source at the bottom of the microscope well.2, adopting the light enhanced film to strengthen lighting effect, is two of feature of the present invention.The effect of light enhanced film is: can uniform irradiation is recycling to the light to all directions on the diffusion film face, penetrate from specific angle, and reach the purpose that strengthens light efficiency at double.3, base plate adopts the purpose of black plate to be: because existing microscope all is furnished with the black and white plate; when need not illumination, the white species of observation or material; make base plate with black panel; when need not illumination, the non-white species of observation or material; turn over and use blank; and the present invention is when adopting the black plate as base plate; (transparent protective glass on the bottom illuminating light source is white just to be equivalent to effect that the present invention not only has (descending) lighting source at the bottom of the microscope; when not throwing light on; just be equivalent to blank); and have the function of black and white plate, and two get at one stroke, replaced the black and white plate.Its technical scheme: by the microscope bottom illuminating light source that the LED-backlit plate constitutes, microscope bottom illuminating light source (10) adopts LED-backlit plate (9), and light enhanced film (2) is arranged on LED-backlit plate (9) diffusion film (8).
The present invention compares with background technology, the one, adopt the LED-backlit plate as microscope at the bottom of (descending) lighting source, the hot spot that has been produced when fundamentally having avoided LED (light emitting diode) illumination that background technology exists, not only illumination is even, and its brightness and photochromic adjustable; The 2nd, the present invention not only has the effect of (descending) light source at the bottom of the microscope, and has the function of black and white plate, and thickness only is 4～6mm, the thickness of the black and white plate that is disposed with former microscope is suitable, and at one stroke two, substituted traditional black and white plate; The 3rd, the light efficiency of LED is higher than incandescent lamp widely, and thermal value will be far below incandescent lamp, can not influence the operator use and to the observation of object.

Embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.By the microscope bottom illuminating light source that the LED-backlit plate constitutes, microscope bottom illuminating light source 10 adopts LED-backlit plate 9.Light enhanced film 2 is that diffusion film 8 is an existing product, is not described herein at this on existing product and the diffusion film 8 that is arranged in LED-backlit plate 9.Transparent protective glass 1 is positioned on the light enhanced film 2, and base plate 4 is the black plate and is positioned on the light reflecting membrane 5 that light reflecting membrane 5 is an existing product, is not described herein at this.LED-backlit plate 9 manufacture crafts are that prior art promptly is made of light reflecting membrane 5, LED (light emitting diode) 6, light guide plate 7, diffusion film 8, and light reflecting membrane 5 and diffusion film 8 lay respectively at light guide plate 7 two sides, and LED (light emitting diode) is positioned at light guide plate 7 sidepieces.Be arranged in LED-backlit plate 9 and be assemblied in framework 3.LED (light emitting diode) is white or red, green, blue, amber or red, green, blue, mixing such as amber.
Embodiment 2: on the basis of embodiment 1, LED-backlit plate power supply lead wire connects optical controller, and this optical controller is a prior art, can control the brightness and the colourity of back light plate.
What need understand is: though the foregoing description is to the present invention's detailed explanation of contrasting; but above-mentioned explanation, just to simple declaration of the present invention, rather than limitation of the present invention; any innovation and creation that do not exceed in the connotation of the present invention all fall within the scope of protection of the present invention.
