Απάντηση: Best of 2010 απο το Secrets(hometheater hi fi)
Since the first LCD units were pressed into service as home theater displays, digital projection has suffered from one limitation, the bulb. No matter the technology – DLP, LCoS or LCD – all digital front projectors use either a UHP (Ultra High Pressure) mercury or xenon lamp as a light source. This presents several obstacles. First, the lamp has to be replaced every so often. It can last as much as 4000 hours but sometimes it’s as little as 1000. Secondly, the lamp shifts color and dims as it ages. In fact, I will usually replace mine at 1000 hours regardless of the rating due to the lowered light output. The color shift also requires re-calibration at regular intervals. I always recommend adjustments at 100, 400 and 800 hours to maintain the most accurate image. Third, lamps run hot requiring a constant-running cooling fan to keep the projector from overheating. There must be a better way.
μπραβο στη RUNCO που εφτιαξε αυτο το μηχανακι,εστω κιαν ειναι τσουχτερο για τις περισσοτερες τσεπες,αλλα αυτο που θελω να ξερω εγω ,αυτα τα παραπανω που τα ξερουμε ΟΛΟΙ,οι υπολοιπες εταιριες ΔΕΝ τα ξερουν και ΑΚΟΜΑ πουλανε λαμπιτσες?:144:
