Publication number: 20080036978Abstract: A projecting apparatus includes a power, a lamp, and a thermal controlling module. The lamp is energized from the power. The thermal controlling module includes a blower, an air duct, and a thermal break. The blower and an air duct, which connects the lamp and the blower, are for making and directing airflow through the lamp. The thermal break is electrically connected to the power and the lamp, and is disposed on the air duct and positioned adjacent the lamp. When the temperature in the projecting apparatus exceeds a predetermined value, the thermal break becomes a turnoff so as to allow the projecting apparatus to be shut off.Type: ApplicationFiled: August 9, 2006Publication date: February 14, 2008Applicant: BENQ CORPORATIONInventors: Tzu-Huan Hsu, Chien-Ming Lee, Tsung-Hsun Wu

Publication number: 20080002156Abstract: An optical projector comprising a main body and a sensing module is provided. The main body comprises a controlling unit, a heat-dissipating unit, a projection lens for projecting an image and at least a vent. The sensing module is disposed in the main body. The sensing module and the heat-dissipating unit respectively are electrically connected to the controlling unit. The hot air inside the main body exchanges with the cool air outside the main body through the vent. When the sensing module detects an external object approaching the vent, such as entering a predetermined range around the vent, the sensing module sends a signal to the controlling unit for activating an anti-overheating mechanism; for example, actuating the heat-dispersing unit or/and displaying a warning image on a screen.Type: ApplicationFiled: May 29, 2007Publication date: January 3, 2008Applicant: BENQ CORPORATIONInventor: Tzu-Huan Hsu
