Abstract
A demonstrator for the secret of colors is composed of a cassette, a power supply controller, a light source, a reflector panel, and the like, wherein light emitting diodes are used as the light source; the brightness of each light emitting diode can be changed; the light emitting diodes respectively sent out a red light beam, a green light beam, a blue light beam and a white light beam which are reflected to the reflector panel; one surface of the reflector panel is provided with a plurality of color strips with different colors; when different color light is emitted to the color strips, different colors are displayed; the central zone of the other surface of the reflector panel is white, and both sides are provided with color blocks with different colors. When two or three kinds of color light are reflected on the white panel, the color change of the light can be observed by regulating the brightness of the color light after the light is mixed.
Description
Technical field
The utility model belongs to a kind of teaching aid.
Background technology
Obtaining coloured light often has two kinds of methods, the one, utilize ordinary incandescent lamp to send white light after, by color filter, allow a kind of light of color pass through, the shortcoming of this method is the cost height, but power can be very big.The 2nd, utilize light emitting diode, it can directly produce monochromatic light, and the shortcoming of this method is that power is less, but that advantage is a cost is very low.
Summary of the invention
The utility model provides a kind of demonstration teaching aid about color, utilizes light emitting diode to produce monochromatic light, and the light of different colours is mixed, show the color that makes new advances, allow different color light be radiated on the colour band, demonstrate different colors, thereby the color of light and the color secret of object are described to the student.
Technical matters to be solved
Obtain monochromatic source cheaply, the adjustable brightness joint of light, and allow two or more monochromatic light mix easily, demonstrate change in color.
The technical scheme of dealing with problems
The utility model is made up of magazine, power-supply controller of electric, light source, reflector etc., light source is a light emitting diode, every light-emitting diode luminance can change, send red, green, blue, beam of white light respectively, invest reflector, the colour band of many different colours is arranged on the reflector one side, and the another side central area of reflector is a white, and there is the color lump of different colours both sides.
Beneficial effect
This product can illustrate the color of light and the color of opaque article to the student easily as teaching aid, is not subjected to the influence of ambient lighting, and is simple in structure, is easy to make, and cost is low, good reliability.
Description of drawings
Fig. 1 is the structural representation of this product, the 1st, and magazine, the 2nd, reflector, the 3rd, light source, the 4th, viewport, the 5th, brightness regulation knob, the 6th, switch, the 7th, power-supply controller of electric;
Fig. 2 is the reflector front;
Fig. 3 is the reflector back side;
Fig. 4 is this product power supply circuit figure.
Embodiment
Make box as magazine with cardboard, glue, sticking black paper is avoided reflective interference in the magazine, magazine top opened round viewport, make light source with red, green, blue, white four light emitting diodes, light emitting diode is loaded in the little iron pipe, fixes, be adsorbed on the iron plate by magnet with hot melt adhesive.Make the independent regulated power supply of four road voltages with circuit of three-terminal voltage-stabilizing integrated, to four diode power supplies, adjusting knob can change the brightness of light emitting diode.Be stained with two book type magnet at the magazine other end, the reflector that iron plate is made is inhaled in box.During use, light a kind of light emitting diode of color successively separately, with a kind of illumination of color on colour band, observing monochromatic light impinges upon on the colour band, the colour band change in color is lighted the light emitting diode of two or three kinds colors more simultaneously, mixes on the white reflection plate, by with color lump color contrast on every side, observe coloured light and mix the back change color.
Claims (1)
1, a kind of mystery demonstration device of color, it is characterized in that: form by magazine, power-supply controller of electric, light source, reflector etc., light source is a light emitting diode, every light-emitting diode luminance can change, send red, green, blue, beam of white light respectively, invest reflector, the colour band of many different colours is arranged on the reflector one side, the another side central area of reflector is a white, and there is the color lump of different colours both sides.
