Abstract

The invention provides a rotary festoon lamp acoustooptical device on a model airplane, belonging to a sport entertainment model aircraft. Color light-emitting tubes and acoustic equipment are arranged on the positions which are seen easily on the body and wings of the model aircraft and propellers, therefore, when in flight, favorite songs and analog sounds can be heard in the air, and when in night flight, the light-emitting tubes arranged on the propellers rotate to form color light rings with different sizes, thus adding a beautiful and splendid view for night sky. In addition, operators can judge the flight direction and high-low orientation of the model airplane through the fixed festoon lamps and rotary festoon lamps on the model airplane in night flight. The rotary festoon lamp acoustooptical device on the model airplane has the advantages of enabling the model airplane to adapt to the flight environments in day and at night, greatly attracting and increasing the interests of people in the model airplane, and playing a promoting role in wide development of model airplane activities and promotion and popularization of model airplane equipment.

Rotary festoon lamp acoustooptical device on model airplane

Technical field

The invention belongs to adult's sports and amusement, toy for children, students in middle and primary schools' science popularization equipment aircraft, relate generally to the wireless remotecontrol rotary festoon lamp acoustooptical device on model airplane.

Background technology

The microlight-type electric remote-control simulated model airplane, because of in light weight, flying speed is low, uses the place little, and the pollution-less flying line time is long and adapted to flight environment of vehicle widely, and extremely children, students in middle and primary schools and adult's door likes and likes.Especially, simulated model airplane can two meters the height low latitudes closely low speed, when flying for a long time, valuable enough chances of viewing and admiring are provided, bring incomparable fast happy happiness to people, also thirst for making something perfect even more perfect to simulated model airplane, if can do various flight grace action freely aloft simultaneously viewing and admiring simulated model airplane, can hear melodious melodious music and song or the various simulated sound play from aerial aeromodelling airplane again, more increase interest and the hobby of people model plane flight.In addition when the curtain of night comes; can't continue flight because of can't see aeromodelling airplane aloft; as on model plane fuselage and wing, installing and fixing color lamp and rotary festoon lamp; having increased to aeromodelling airplane can be in the function of flight at night; fixedly color lamp and rotary festoon lamp simultaneously; can also help to grasp the flight orientation of judging model plane from personnel accurately; not only make aeromodelling airplane expand flight environment of vehicle; also create more flying machine meeting and condition, be scientific and technological activities students in middle and primary schools to aeromodelling airplane to people; toy for children; popularizing of the aeromodelling airplane equipment that uses in the adult sports and amusement will be played greatly promotion and impetus.Rotary festoon lamp acoustooptical device on model airplane is through inquiry State Patent Office CD patent of invention, no this item patented technology.

Summary of the invention

Purpose of the present invention, simple function and the defective that can only fly by day at present international and domestic aeromodelling airplane, design provides a kind of fixedly color lamp and rotary festoon lamp that is installed on the aeromodelling airplane, installed sound equipment simultaneously additional, the purpose that makes aeromodelling airplane realize promptly having the sound can in environment round the clock, fly again.

Basic design of the present invention is, rotary festoon lamp acoustooptical device on model airplane by fixing color lamp, rotary festoon lamp, and three parts of the sound form; Fixedly color lamp is after connecting with lead or with the flexible circuitry connection in series-parallel with several colorful light-emitting diodes, be installed on the fuselage of aeromodelling airplane and each position visibility point that wing can be seen easily, after rotary festoon lamp connects with lead or with the flexible circuitry connection in series-parallel with several colorful light-emitting diodes, be installed on the independent slewing or directly be installed on the screw of aeromodelling airplane, power supply mode: can take the two conducting ring power supplies of single brush list conducting ring power supply or double brush, be packed in brush or conducting ring on the independent slewing or directly be fixed on the screw of aeromodelling airplane, also can adopt other multiple power supply mode, this device power supply mode: adopt single brush list conducting ring and utilize screw metal shaft electrically conducting manner, sound part: utilize musical film and acoustical generator to be installed on the aeromodelling airplane.

Description of drawings

Accompanying drawing is the rotary festoon lamp acoustooptical device on model airplane structural representation.

Piece number explanation among the figure:

1, fixedly color lamp, 2, sound equipment, 3, rotary festoon lamp, 4, power supply, 5, switch, 6, current-limiting resistance_R1, 7, elastic sheet metal, 8, screw metal shaft, 9, current-limiting resistance_R2, 10, elastic metallic brush, 11, annular electrode, 12, lead.

Specific implementation method

Below in conjunction with accompanying drawing optimum implementation of the present invention is described, rotary festoon lamp acoustooptical device on model airplane comprises fixedly color lamp 1, sound equipment 2,rotary festoon lamp 3, at fixing color lamp 1: power supply 4 decent switches 5, the colorful light-emitting diode after being connected connection in series-parallel_D1-Dn1 positive pole,_D1-Dn1 negative pole serial connection current-limiting resistance_R1It is negative to be connected power supply 4 after 6.Sound equipment 2: sound equipment 2 is connected in parallel on the power supply 4 through switch 5.Rotary festoon lamp 3: power supply 4 decent switches 5, current-limitingresistance_R29, elasticmetallic brush 10,annular electrode 11,lead 12 lead wherein are fixed in rotary festoon lamp in thepropeller_D1-Dn3 positive pole,_D1-Dn3 negative pole, be fixed on the end ofscrew metal shaft 8 through another lead oflead 12, the other end ofscrew metal shaft 8 contacts with back contact elastic sheet metal 7, elastic sheet metal 7 and 4 negative connections of power supply.

Model plane are when working flight, and power supply 4 is seriously manual or by after remote control switch 5 connections, warp is color lamp fixedly_D1-Dn1 and current-limiting resistance_R16 to power supply 4 negative formation loops, are installed in the fixedly color lamp on model plane fuselage and the wing_D1-Dn1 light emitting diode begins luminous.Simultaneously sound equipment 2 is also connected with power supply 4, and the sound equipment 2 that is installed on the model plane is started working, send setting or music and song or the various simulated sound selected by remote control switch.Rotary festoon lamp_D1-Dn3: power supply 4 decent switches 5, current-limitingresistance_R29, elasticmetallic brush 10,annular electrode 11,lead 12 lead wherein are to rotaryfestoon lamp_D1-Dn3 positive pole,_D1-Dn3 negative pole begins luminous through another lead,screw metal shaft 8, the elastic sheet metal 7 oflead 12 with the power supply 4 negative loops that connect and compose, because aeromodelling airplane screw when flight rotates, the light emitting diode that sends different colours of the diverse location that install on the screw this moment has formed the ring of light of the colorful beauty that varies in size on the Plane of rotation of screw.When manual or remote control switch 5 disconnected, the rotary festoon lamp acousto-optic device on the aeromodelling airplane quit work.
