A rear projection television includes a casing with a space therein and a plurality of modular units. A plurality of maintenance holes are formed through the casing to communicate with the space. The modular units are positioned in the space to correspond to the maintenance holes. When one component inside the casing needs repairing, only a lid covering the corresponding maintenance hole is dismounted for the user to quickly take the component out, without moving the casing. Thereby, the repair process is simplified with saved repair labor and space.

Easy-maintain rear projection television

An adjustment apparatus of a reflection mirror is disclosed, the apparatus comprising a holding base plate, an affixing block affixed on the holding base plate, at least one adjusting set, and a rotatable chassis affixed onto the affixing block, wherein the reflection mirror is affixed on the rotatable chassis. Moreover, the adjusting set comprises an adjusting screw and an adjusting spring. The adjusting screw is mounted onto the holding base plate and transpierces the holding base plate to fix an extending portion of the rotatable chassis. The adjusting spring associated with the adjusting screw supports an extending portion of the rotatable chassis to counterbalance the adjustments in the adjusting screw. When the adjusting screw is rotated in, the rotatable chassis rotates along a first direction and compresses the adjusting spring. When the adjusting screw is rotated out, the rotatable chassis rotates along an opposite direction to the first direction and stretches the adjusting spring.

Angle-adjusting apparatus for a reflection mirror in a rear-projection TV

The present invention sucks the air from the fan at the top of the imaging assembly of the optical engine and blows the air via the air duct device downward. Some of the air is guided by the diversion board, aslant guiding surface, and aslant isolating board of the air duct device and blown into the imaging assembly for cooling the optical components. Some of the air is guided through a first air duct, a second air duct, and a third air duct extended from the outside of this main body respectively to the outer surface of the light valves. Further, some of the airflow is guided into a branch air duct and blown to a vent of the imaging assembly. By means of the changing direction diversion board, the airflow is guided towards the polarizer module, and flows out from a vent on the other side.

Cooling apparatus for optical engine assembly

The present invention comprises a polarizer adhered on a flange plate at the top end of a L-shape base, an aslant surface on one side of the base, two sleeve screws protruded from the center of the aslant surface, an air duct defined between an upper base and a lower base of a Z-shape fixed base, two slots disposed on the lower base for receiving the sleeve screws, and two fixing bolts securing the washers onto the sleeve screw to limit the fixed base on the aslant surface of the base. A supporting surface is formed at a flange disposed downward at both ends of the upper base of the fixed base for gluing a half-wave plate. An adjusting mechanism protruded from the lower side of the fixed base extends into a recess at the lower end of the aslant surface; a screw hole is disposed on a side of the base and having an adjusting slot with its end propping one side of the adjusting mechanism; and an elastic member with its ends respectively fixed to a side of the base and a hole of the adjusting mechanism. The adjusting mechanism at the lower side of the fixed base adjusts the half-wave plate to an optimal polarized position.
