Ib qho LED hologram ntxuam tsim qhov illusion ntawm ntab 3D duab los ntawm kev sib txuaspersistence of vision (POV), kev sib hloov ceev, thiabsynchronized LED tswj-nws tsis yog qhov tseeb hologram tab sis muaj qhov ntim ntim POV zaub.
Txoj Cai Ua Haujlwm Core
Tib neeg lub qhov muag khaws ib daim duab rau txog0.04–0.1 feebtom qab lub teeb ci ploj mus. Los ntawm spinning LED-mounted blades sai heev thiab flashing LEDs nyob rau hauv meej sync nrog kev sib hloov, lub hlwb merges discrete lub teeb ntsiab lus rau hauv ib tug nruam, floating 3D duab.
Step-by-Step Mechanism
Kev teeb tsa kho vajtse
Cov hniav nyias nrog tuabLED strips(feem ntau RGB) raws lawv qhov ntev.
High-speed brushless lub cev muaj zog spinning ntawm1,000-3,000 RPM(≈17–50 kiv puag ncig ib ob).
Microcontroller rau real-time synchronization ntawm lub cev muaj zog txoj hauj lwm thiab LED sij hawm.
Kev npaj cov ntsiab lus
3D qauv / yeeb yaj duab yoghlais rau hauv nyias ntsug ncejsib raug rau tus kiv cua txoj haujlwm tig.
Software maps txhua daim rau cov LEDs tshwj xeeb thiab cov kaum sab xis.
Synchronized Illumination
Raws li cov hniav tig, tus maub los ua rau LEDs rauflash ON / OFF ntawm lub sijhawm tiag tiagkom "kos" ib daim duab ntawm ib qho kev sib hloov.
Ntawm qhov nrawm nrawm, cov ntu ntu ntu sib tshooj hauv koj lub zeem muag los tsim ib qhotsis tu ncua, volumetric 3D duabuas zoo nkaus li ntab hauv nruab nrab huab cua.
Tus kiv cua siv qhov no li cas
LED sawb ntawm cov hniav
Ib kab ntawm RGB LEDs yog kos nrog txhua tus kiv cua. Lub kiv cua tig ntawm kev kub ceev (feem ntau 600-2600 RPM).
Txoj hauj lwm sensor
Lub sensor (feem ntau yog Hall effect lossis infrared sensor) taug qab raws nraim qhov twg cov hniav nyob rau hauv ib qho instant. Qhov no qhia tus tswjthaumkom flash txhua LED.
Controller xa cov cim raws sijhawm
Tus maub los khaws cov duab lossis cov yeeb yaj kiab ua tus qauv ntawm cov dots (zoo li bitmap). Raws li cov hniav rotates, tus maub los qhia txhua lub LED yam xim twg los tig rau thiab ntev npaum li cas, raws li cov hniav lub kaum sab xis tam sim no.
Kev nrawm nrawm tsim cov duab
Txhua LED blinks ntau txhiab zaus hauv ib ob. Vim hais tias cov hniav txav ceev heev, cov flashes sau ib lub cylindrical ntim ntawm qhov chaw. Koj ob lub qhov muag pom tag nrho cov ntsiab lus ntawm lub teeb ua ke, tsim ib daim duab uas zoo nkaus li ntab hauv nruab nrab huab cua.
Animations thiab 3D nyhuv
Los ntawm kev hloov cov qauv flashed me ntsis rau txhua qhov kev sib hloov, tus kiv cua qhia cov duab txav. Thiab vim tias daim duab tau kos rau ntawm lub dav hlau 2D, tus kiv cua tuaj yeem tsim qhov kev xav tsis zoo ntawm qhov tob (xws li lub logo spinning lossis npauj npaim flapping nws tis).
Summary (ib kauj ruam-by-step)
Ntxuam spin → hniav yuav luag tsis pom.
Sensor lem hniav txoj hauj lwm.
Controller teeb txhua LED nyob rau lub sijhawm zoo meej.
POV muab cov flashes rau hauv daim duab khov kho.
Kev hloov pauv sai sai ua rau cov animation thiab qhov tob.
Qhov ntawd yog cov khawv koob tom qab qhov muag pom "hovering" logos thiab animations koj pom hauv khw lossis hauv kev ua lag luam.
Visual Effect
Cov hniav txav nrawm dhau kom pom meej, tsuas yog tso cov duab ci ntsa iab xwb.
Qhov tshwm sim yog aiav-dawb, ntau lub kaum sab xis 3D illusiontsis muaj lub cev screen.
