PROJECTING APPARATUS AND THERMAL CONTROLLING MODULE THEREOF
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.
1 . A projecting apparatus comprising:
a power;
a lamp energized from the power;
a blower and an air duct, which connects the lamp and the blower, for making and directed an airflow through the lamp; and
a thermal break electrically connected to the power and the lamp, disposed on the air duct and positioned adjacent the lamp;
wherein 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.
2 . The projecting apparatus according to claim 1 , wherein the thermal break is positioned at the horizontal which is substantially equidistant from upper and lower edges of the lamp.
3 . The projecting apparatus according to claim 1 , wherein the thermal break is disposed on the sidewall of the air duct.
4 . The projecting apparatus according to claim 1 , wherein the thermal break exposes to the inner wall of the air duct.
5 . The projecting apparatus according to claim 1 , wherein the thermal break is covered by a metal layer.
6 . The projecting apparatus according to claim 5 , wherein the metal layer comprises copper.
7 . A thermal controlling module for a projecting apparatus, the projecting apparatus comprising a power and a lamp energized therefrom, the thermal controlling module comprising:
a blower and an air duct, which connects the lamp and the blower, for making and directing an airflow through the lamp; and
a thermal break electrically connected to the power and the lamp, disposed on the air duct and positioned adjacent the lamp;
wherein 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.
8 . The projecting apparatus according to claim 7 , wherein the thermal break is positioned at the horizontal which is substantially equidistant from upper and lower edges of the lamp.
9 . The projecting apparatus according to claim 7 , wherein the thermal break is disposed on the sidewall of the air duct.
10 . The projecting apparatus according to claim 7 , wherein the thermal break exposes to the inner wall of the air duct.
11 . The projecting apparatus according to claim 7 , wherein the thermal break covered by a metal layer.
12 . The projecting apparatus according to claim 11 , wherein the metal layer comprises copper.
