Abstract: A projector includes a projection lens, an optical engine, and a light device. The light device has a lighting axis and includes a movable frame, two light sources fixedly disposed on the movable frame, and a driving part kinematically connected with the movable frame. The driving part is disposed in front of the two light sources. The driving part moves the movable frame such that the two light sources moves simultaneously so as to selectively make one of the two light sources emit light along the lighting axis, which avoids single light source operating for long time. The optical engine is disposed close to the light device and has a light entrance axis. The light entrance axis coincides with the lighting axis. The optical engine includes a digital micromirror device that modulates light from the light device to be projected out the projector through the projection lens.

Abstract: A projection device includes a first light source, a second light source, a driving unit, a reflecting member and a light integrator. The driving unit and the first light source are located at opposite sides of a second light axis of the second light source. The driving unit and the second light source are located at opposite sides of a first light axis of the first light source. The driving unit drives the reflecting member to move between a first position and a second position. When the reflecting member is located at the first position, the first light source emits a first light along the first light axis to the light integrator. When the reflecting member is located at the second position, the second light source emits a second light along the second light axis and the reflecting member reflects the second light to the light integrator.

The second ring structure is clamped between the holding casing and the containing casing for sealing the containing space cooperatively with the connection ring structure and the first ring structure when the containing casing is fixed to the holding casing.

Abstract: A touch projection system includes a light source device, a micromirror device, and an image-capturing device. The micromirror device can provide three reflection directions. The micromirror device can selectively reflect projection light emitted by the light source device in one of the reflection directions to project the reflected projection light onto a screen to form an image. The micromirror device also can reflect image light from the screen in another one of the reflection directions. Further, the micromirror device can reflect the image light from the screen in the other one of the reflection directions, which has a larger deflection angle, to be received by the image-capturing device, for example for determining a touch operation performed on the screen. Thereby, the limitation of structural interference by other components to the image-capturing device is reduced, so that the touch projection system can be assembled in a compact configuration.

Abstract: A touch projection system includes a screen, an image-capturing device, a micromirror device, and a TIR prism disposed in front of the micromirror device. The TIR prism includes an optical path compensation structure or a hollowed channel, so that an image light from the screen, traveling through the TIR prism to be reflected by the micromirror device, can travel through the optical path compensation structure or the hollowed channel to avoid a probable optical path difference on the image light due to traveling through the TIR prism. Thereby, the invention can solve that a distortion may be induced in a touch image formed by the image-capturing device receiving the image light reflected by the micromirror device.

Abstract: A projector with single fan including a casing, a heat source, a light source module and an axial-flow fan are provided. The casing has an air outlet and a first air inlet. The heat source, the light source module and the axial-flow fan are disposed in the casing. The light source module includes a lamp shade and a light-emitting part. The axial-flow fan is disposed in a light outgoing side of the light source module and has an airflow inlet and an airflow outlet. When the axial-flow fan is operating, a first airflow is generated. After flowing through the heat source, the first airflow enters the airflow inlet and generates a second airflow. The second airflow, blown out from the airflow outlet, dissipates the heat generated by the light source module and then flows out to the outside of the casing.

Abstract: The invention discloses a projector including a casing, an optical module, a light source module, a blowing fan, and an axial fan. The casing has a first air-outlet, a second air-outlet, and an air-inlet. The blowing fan and the axial fan are disposed corresponding to two sides of a light axis of the light source module respectively. When the blowing fan operates, an initial airflow into the casing from the air-inlet flows through the optical module and then a predetermined airflow generated by the blowing fan on a first air-outlet surface of the blowing fan cools the light source module. An angle is formed between the axial fan and one side of the casing. The axial fan directly sends the air around the light source module out of the casing through the first air-outlet and/or the second air-outlet.

Abstract: The invention provides an electronic apparatus including a casing, a thermal sensor, a controlling unit, an air filter and a cooling fan. The air filter is detachably attached to the inlet of the casing. When the air filter is attached to the inlet of the casing, a partial structure of the air filter neighboring the thermal sensor blocks an airflow from flowing through the thermal sensor. In particular, when the air filter is attached to the inlet of the casing, or when the air filter is not attached to the inlet of the casing, the controlling unit always calculates a determined speed by applying the temperature sensed by the thermal sensor in a function of speed versus temperature, and controls the cooling fan operating under the determined speed to cool the electronic apparatus.

Abstract: The invention discloses an electronic apparatus and a projector by use of two passages formed in a casing for two air-flows passing through, each of which is generated by at least fan. Heat-dissipation devices are disposed in the passages substantially evenly so as to dissipate the heat generated in operation by an optical module disposed in the casing by the air-flows. The purpose of efficient usage of the apparatus space is therefore achieved. For the basis of special heat-dissipation requirement and assembly design, one of the fans is disposed between two of the heat-dissipation devices so that the two heat-dissipation devices could obtain better heat-dissipation efficiency; further, there could be an open space disposed between two of the heat-dissipation devices and adjacent to a light source of the optical module for the installation of the light source and the following installation of the fan, so that the whole volume of the electronic apparatus or the projector could be further reduced.
