Abstract
A kind of redgreenblue electric candle for probing into convex lens image-forming discipline, including candle bar, candle body, candle flame, the candle flame is made of circuit board and one, left side green curve small bulbs, one, the right blue curve small bulbs, an intermediate red straight line small bulbs, and the red straight line small bulbs in centre one have the center that a bigger red small bulbs represent candle flame.Advantageous effect is：Imitate the flame of point lighted candle, not only have any different up and down, also it has any different left and right, when probing into convex lens image-forming discipline convenient for student, observation changes as the left and right with object, an intermediate red straight line small bulbs have the center that a bigger red small bulbs represent candle flame, are conducive in experimentation, adjust the center at the center of candle flame, the center of convex lens and optical screen substantially in sustained height.In conclusion using the candle student experimenting, the shortcomings that overcoming a lighted candle student experimenting, the advantages of remaining a lighted candle student experimenting, effect is preferable, perfect interesting.
Description
【Technical field】
The present invention relates to a kind of electric candle more particularly to a kind of RGB for probing into convex lens image-forming discipline of teaching
Three color electric candles.
【Background technology】
In physics teaching material,《Probe into the rule of convex lens》Student experimenting teaching in, be using point lighted candle candle
Flame studies the rule of convex lens as object.Student utilizes the candle flame of a lighted candle during experiment of starting
Although more satisfactory by convex lens effect as object, shortcoming is also fatal, except the candle flame of lighted candle
Outside the shortcomings that easily scald student, stream wax easily makes desktop dirty, also have a disadvantage that：1., the first step in experimentation, to adjust
The center at the center of candle flame, the center of convex lens and optical screen is saved substantially in sustained height, but in the candle flame lighted
The heart is bad to be determined.2., in experimentation, to study as and the left and right of object whether change, but candle flame as object thereon
Under have any different, but left and right be not different, therefore left and right not can determine that.
【Invention content】
It is an object of the invention to the candle flame of a lighted candle is overcome to study convex lens image-forming discipline as object and have
Apparent disadvantage mentioned above and a kind of redgreenblue electric candle for probing into convex lens image-forming discipline provided
The present invention is achieved through the following technical solutions：A kind of redgreenblue electricity for probing into convex lens image-forming discipline
Sub- candle, including candle bar, candle body, flame of lighting up, with candle body connection above the candle bar, side is described with candle flame connection with it for the candle
There is switch with candle, have battery in body of lighting up, the candle flame is by circuit board and one, left side green curve small bulbs, one, the right indigo plant
As soon as color curve small bulbs, intermediate red straight line small bulbs composition, in this way, the fire of candle that the imitation being really true to life is lighted
Flame, the red straight line small bulbs in centre one have the center that a bigger red small bulbs represent candle flame.
The beneficial effects of the present invention are：A kind of redgreenblue electric candle for probing into convex lens image-forming discipline imitates
The flame of point lighted candle, not only has any different up and down, and left and right is also had any different, and the left side of two curve small bulbs is green on flame of lighting up,
The right is blue, and by convex lens, imaging, the left side are blue on optical screen, and the right is green, just left with candle flame color
Right on the contrary, when probing into convex lens image-forming discipline convenient for student, observation changes as the left and right with object, an intermediate red straight line lampet
Bubble has the center that a bigger red small bulbs represent candle flame, is conducive in experimentation, adjust candle flame center,
The center of convex lens and the center of optical screen are substantially in sustained height.In conclusion using the candle student experimenting, overcome and light
The shortcomings that candle student experimenting, the advantages of remaining a lighted candle student experimenting, effect is preferable, perfect interesting.
【Description of the drawings】
Fig. 1 is a kind of redgreenblue electric candle for probing into convex lens image-forming discipline of the present invention, reference numeral：1st, it lights up
Bar；2nd, candle body；3rd, candle flame；21st, it switchs；22nd, battery；31st, circuit board；32nd, one, left side green curve small bulbs；33rd, the right
One blue curve small bulbs；34th, intermediate one red straight line small bulbs；35th, bigger red small bulbs.
【Specific embodiment】
Below in conjunction with the accompanying drawings and specific embodiment is described further the present invention：
Embodiment 1
A kind of redgreenblue electric candle for probing into convex lens image-forming discipline, it is described including candle bar 1, candle body 2, candle flame 3
1 top of candle bar is connected with candle body 2, and 2 top of candle body is connected with candle flame 3, has switch 21 on the candle body 2, has electricity in body 2 of lighting up
Pond 22, the candle flame 3 by circuit board 31 and one, left side green curve small bulbs 32, one, the right blue curve small bulbs 33,
As soon as intermediate red straight line lampet 34 forms, in this way, the flame of candle that the imitation being really true to life is lighted, the centre one
Red straight line small bulbs have the center that a bigger red small bulbs 35 represent candle flame 3.
According to the disclosure and teachings of the above specification, those skilled in the art in the invention can also be to above-mentioned embodiment party
Formula carries out appropriate change and modification.Therefore, the invention is not limited in specific embodiment disclosed and described above, to this
Some modifications and changes of invention should also be as falling into the scope of the claims of the present invention.In addition, although this specification
In used some specific terms, but these terms are merely for convenience of description, do not limit the present invention in any way.
