What are the types of proα≠¶jectors?

1. Home use type: it is∞• mainly used to optimize the♥♠ video, which is characte®∏πrized by brightness o< φf about 1000 lumens, high contrast, 16≈≥<§:9 aspect ratio of projection picture,∏Ω✔↓ complete video ports, sui≤δ"±table for playing movies and hig★↔‌h-definition TV, and suitable fo§>©r home users. Portable business projβ↑ector: generally, a proj☆$ ector weighing less than 2kg is defined₩  as a business portable projector,®"→ which is as heavy as a light laptop. T""he advantages of bus₹↕iness portable projector are small siz≈Ωe, light weight and s©Ω★≥trong mobility. It is ×φthe substitute of traditional slide pr∞©ojector and large and med$ ium-sized projector. The ∏φcombination of light a<ε<↑nd thin notebook computer∏↓σ and business portable proj‍‌₹πector is the first choice for mobile 𶶥business users in mobile business dem☆π§onstration.



2. Educational conference type: it$‍ is generally oriented t$σ§≈o school and enterprise appli☆ ​£cations, with mainstrea&♠m resolution, brightness of about 2000£ ε-3000 lumens, moderate weight, go׶​®od heat dissipation and dust prevent§φion, suitable for installation a'→≥nd short-distance movement, rich functi↓₩≠onal interfaces, easy maintenance, r★'elatively high performance priαπce ratio, suitable for m£↔®ass purchase and popularizatioδΩ↔n.



3. Mainstream project type:✘λ₽ compared with the mainstream or®←÷♠dinary projectors, the proj♣β♣×ect projectors have l↓♠₩arger projection areα≠♣₩a, longer distance and high briλ™ghtness, and generally support multi &σ☆×light bulb mode, which can be↑ ®tter cope with large and va'→riable installation environment, a∞§↕nd are suitable for education♠♦, media, government and other fi'♠↕×elds.



4. Professional type: this kindπ÷♣♠ of projector pays more attention to ♦∑stability, emphasizes low failure rate,γ‍ and has strong heat dissipation ↑Ω performance, network★® function, convenient use, etc. Oσ&•♣f course, in order to adaptγ ↕ to a variety of professional a×←↔εpplications, the most importa§®≤nt feature of the shadow instrument is β♥its high brightness, which'×× generally can reach more tha∑¶∑n 5000 lumens, and theβ"↑& high one can exceed 100"β♦ 00 lumens. Due to it≠≤s large volume and heavy weigh&§★→t, it is usually used for ↑★special purposes, such as theγ•ater, museum, great hall, public area,‌< and also for monitoring traffλ×≈©ic, public security comma¶♦nd center, fire control and air traffic±✔ control center.



5. Measuring projector: this kind of p✔∞&↔rojector is different from the≤₽β above kinds of projectors. It©✔π✔ was called contour projector in the e↔↑arly days. With the popularization​★ of grating ruler, all projectors are×$ ≥ installed with high-precisio$π n grating ruler, whi‍£♦ch is also called measur<εing projector. In order to dist'‌•inguish from the tradi₽ tional projector, this kin♠←d of projector is called measurin☆'g projector. Its main func✘ tion is to form an enlarged projector ‍↕εthrough the transmission o↓↔₽f light, and then determine t≈$he size of the product with st¶§®¥andard film or gratin♦←​g ruler. Due to the developm®±☆★ent of industrialization, this kind of ≥↔measuring projector has become one←₩π≥ of the most commonly used measurin★γ★g instruments in the m↔ ☆anufacturing industry. ≥•The regular projection mode is↔₽€ divided into vertical proje δ≤ctor and horizontal projector.♣↑ε✘ According to different standa$σ‍Ωrds, it can be divide¥€∑×d into contour projectoγεr and digital projector.
