Abstract

The utility model relates to a light guide plate for illumination of microscope bottom, comprising a LED light emitting diode and a light guide plate, wherein, the light guide plate is round, and the LED light emitting diode is built in the light guide plate. The utility model has the advantages of uniform illumination, no spot halo and not causing glare.

Description

Illumination backlight plate at the bottom of the microscope
Technical field
The utility model relates to illuminating light guide plate at the bottom of a kind of microscope, belongs to illumination manufacturing field at the bottom of the microscope.
Background technology
At present, the stereomicroscope bottom illuminating light source of selling on the market has single of employing or many white light LEDs to make light source replace incandescent (or fluorescent light), is driven by circuit supply, adds an acute-matte thereon, makes it to produce a uniform illumination light.Advantage: though this led light source can avoid producing a large amount of heats, improve light efficiency, arranged long serviceable life.Shortcoming: light source that above-mentioned ray structure produces may be sent by many white light LEDs, it is dizzy to form the hot spot corresponding with white light LEDs quantity at acute-matte, inhomogeneous, and light source has reflection at glass surface, make light not concentrate up ligthing, but disperse from all directions, the luminous energy that is actually used in microexamination seldom, remaining light then can cause dazzles the eyes.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, it is dizzy to design a kind of hot spot that neither can produce, can be at the reflection of glass surface light source yet, can not cause illumination backlight plate at the bottom of the microscope of dazzling the eyes yet.
Design proposal: in order to realize above-mentioned purpose of design.1, the LED light emitting diode being built in the light guide plate, is one of feature of the present utility model.The purpose of doing like this is: because the light that the LED light emitting diode sends is direct projection light, and be built in interlaced, the equal light of formation illumination of light that a plurality of LED light emitting diodes in the light guide plate send.2, light guide plate being designed to circular configuration is two of feature of the present utility model.The purpose of doing like this is: because light guide plate is circle distribution, is radioactivity and evenly distributes and be built in light that the LED light emitting diode of leaded light inside circumference sent, it is dizzy not only can not produce hot spot, dazzles the eyes nor can cause.Its technical scheme: illumination backlight plate at the bottom of the microscope, it comprises LED light emitting diode and light guide plate, and light guide plate is rounded, and the LED light emitting diode is built in the light guide plate.
The utility model is compared with background technology, and the one, illumination is even; The 2nd, it is dizzy can not produce hot spot; The 3rd, can not become to make and dazzle the eyes.
Description of drawings
Fig. 1 is the structural representation of illumination light guide plate at the bottom of the microscope.
Fig. 2 is the perspective view of illumination light guide plate at the bottom of the microscope.
Embodiment
Embodiment 1: with reference to attached Fig. 1 and 2.Illumination backlight plate at the bottom of the microscope, it comprises LED light emitting diode 1 and light guide plate 2, light guide plate 2 is rounded, LED light emitting diode 1 is built in the light guide plate 2, that is to say, existing technologies such as plurality of LEDs light-emitting diodes 1 pipe employing cast are built in the circular light guide plate 2, and light guide plate 2 can be epoxy resin or the like transparent material.
What need understand is: though the foregoing description is to the detailed explanation of contrasting of wooden utility model; but above-mentioned explanation; just to simple declaration of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the present utility model.
