The sample slide 20 of observation is placed on the first supporting rack 40, then glass sphere lens 10 are placed on the second supporting rack 50, is used
Arbitrary lighting source irradiation glass sphere lens 10, after glass sphere lens 10, light beam is converged on sample slide 20, is irradiated to
On sample slide 20, and ensure the focus after convergence between glass sphere lens 10 and sample slide 20, by glass marble
After lens 10, divergent transport is presented in the light beam sent by lighting source, after sample slide 20, carries sample slide
20 sample information, and after transmitting a distance, image information projection blank sheet of paper or white wall etc. are connect on light object, is radiated at and connects
Image on light object is amplification real image, so as to achieve the purpose that microprojection.Compared with existing projection arrangement 1, this practicality
1 small volume of projection arrangement of new offer, lighter in weight, and it is not required mains-supplied that can use, consequently facilitating taking
Band can carry anywhere so that the place of teaching is not limited in classroom；And its cost is well below city
The projection arrangement 1 sold on field greatly reduces the purchase cost of projection arrangement 1.
Difference lies in projection arrangement 1 further includes the embodiment 2 of projection arrangement 1 provided by the utility model with embodiment 1
There is the 3rd supporting rack；First supporting rack 40, the second supporting rack 50 are arranged in parallel successively in the horizontal with the 3rd supporting rack, and the 3rd
Supporting rack is used to place light emitting source 30.When using projection arrangement 1 provided by the utility model, it is necessary to which a light emitting source 30 irradiates
Sample slide 20 to be seen, therefore the 3rd supporting rack is set for placing light emitting source 30.Use can be eliminated by so setting
Person oneself carries the inconvenience of light emitting source 30, user will not occur leaves behind light emitting source 30 to cause projection arrangement 1 that cannot use
Happen.
It is detachably connected between first supporting rack 40, the second supporting rack 50 and the 3rd supporting rack.By the firstth supporting rack
40th, the second supporting rack 50 and the 3rd supporting rack are arranged to there are two detachably connected purposes：One is when need by
When projection arrangement 1 provided by the utility model is carried, projection arrangement 1 can be disassembled and, so that projection arrangement 1
Whole occupied space become smaller, so as to easily facilitate carry；The second is when the first supporting rack 40, the second supporting rack 50 or the 3rd
One among supporting rack is damaged, and can be individually replaced the component of damage, without to projection arrangement 1 it is whole into
Row is replaced, indirect saving cost, also improves the whole service life of projection arrangement 1.
Specifically, light emitting source 30 can be glare light electric torch.Glare light electric torch, also known as LED glare light electric torchs are to shine
A kind of novel illumination instrument of the diode as light source, it has many advantages, such as power saving, durable, brightness is strong；, glare light electric torch can be with
Emit the preferable white light of the depth of parallelism, button cell can be used as power supply.
