Abstract
The utility model relates to a student optical microscope with a simple light source, which comprises other optical microscopes, and is characterized in that a white LED light source is arranged under a carrying platform of the optical microscope and corresponds to the centre of a light through-hole of the carrying platform of the optical microscope. The utility model has the advantages of simple structure, lower manufacturing cost and low application cost of daily used microscopes, can be used for transforming the existing student optical microscopes in middle and primary schools, saves the cost of replacing experimental facilities by the schools, and conforms to the modern environmental requirements of energy saving and emission reduction. The student optical microscope replaces the reflectors on student optical microscopes; students are not influenced by the localization of the external light source when operating the microscope, and meanwhile, beam focusing operation link is left out when students use the microscope, thus being beneficial to the classroom management of teachers and the safety of students, and being more beneficial to cooperative learning of students in class.
Description
Technical field
The utility model relates to a kind of student's optical microscope that carries simple and easy light source.
Background technology
The optical microscope of pupils and students' use at present is to observing the used permeability light source of material illumination, adopt two kinds of forms: the one, below the light hole of microscope stage, reflective mirror is installed, supporting installation illumination daylight lamp on the microscopical laboratory table must used thus, this has just limited school or microscopical field of employment is selected by other research units, can only have the biology laboratory of light source to use on laboratory table; If with natural light outside window is that source reflection enters field of microscope, must limit walking about of microscope periphery personnel again, in order to avoid influence the effect of user's viewing microscope.The 2nd, install and use the light fixture of AC power at Microscope base, for reaching needed uniform light source effect, must cover on the light fixture tool lens optical collector is installed between a slice frosted glass, light fixture and the load again.Because light structures is complicated, operation and maintenance are all more loaded down with trivial details, and owing to still need external power supply, this form of light source has still limited microscopical application places must AC Power supply socket.Therefore demand inventing a kind of student's optical microscope that can address the above problem urgently.
Summary of the invention
The purpose of this utility model is to solve prior art middle school student optical microscope to adopt the existing the problems referred to above of permeability light source, and a kind of student's optical microscope that carries simple and easy light source is provided.A kind of student's optical microscope that carries simple and easy light source of the utility model design, comprise other optical microscopes, it is characterized in that: a white light-emitting diode light source is arranged below the objective table of optical microscope, and the white light-emitting diode light source is corresponding to the light hole circle centre position of the objective table of optical microscope.It is characterized in that: the white light-emitting diode light source is composed in series by white light-emitting diode, battery, switch and potentiometer.The utility model has the advantages that simple in structure, not only cheap for manufacturing cost, and equally very cheap in the microscopical application cost of daily use, can be used for transforming the existing student's optical microscope of each middle and primary schools, save the cost that school replaces experimental facilities, meet the modern environmental requirement of energy-saving and emission-reduction.This device has replaced the student with the reflective mirror on the optical microscope, no longer is subjected to the influence of external light source limitation when the student operates microscope, has omitted the operation link of " to light " when the student uses microscope simultaneously.This device for school further transform biology laboratory the student experimenting table, created condition for the light sources of removing on the laboratory table such as daylight lamp, this helps teacher's class management and student's safety, and more helps the student classroom cooperative learning.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is a white light-emitting diode circuit of light sources principle schematic of the present utility model,
Below in conjunction with drawings and Examples the utility model is elaborated,
Embodiment
Comprise optical microscope 1 among the figure, it is characterized in that: a white light-emitting diode light source 3 is arranged below the objective table 2 of optical microscope 1, and white light-emitting diode light source 3 is corresponding to light hole 4 circle centre positions of the objective table 2 of optical microscope 1. and it is characterized in that: white light-emitting diode light source 3 is composed in series by white light-emitting diode 5, battery 6, switch 7 and potentiometer 8.
During actual the use, can select luminous uniform white luminous LED diode for use, white luminous LED diode is placed the objective table below light hole circle centre position of student's optical microscope, make it face light hole, allow white luminous LED diode from facing toward the microexamination material direct illumination on the slide between the light hole below 1-2 cm distance of objective table below, and utilize potentiometer can regulate the brightness of white luminous LED diode, to obtain the optimal viewing effect.The white luminous LED diode that this device uses is the very low emitting led diode of power consumption, therefore select No. 5 powered battery of common 3V button cell or 2 joint 1.5V for use, can thoroughly discard the lead " tail " that inserts power supply, make the occasion of optical microscope can be wider.
Claims (2)
1. student's optical microscope that carries simple and easy light source, comprise optical microscope, it is characterized in that: a white light-emitting diode light source is arranged below the objective table of optical microscope, and the white light-emitting diode light source is corresponding to the light hole circle centre position of the objective table of optical microscope.
2. by the described a kind of student's optical microscope that carries simple and easy light source of claim 1, it is characterized in that: the white light-emitting diode light source is composed in series by white light-emitting diode, battery, switch and potentiometer.
