Abstract: An optical engine device with a heat dissipation function suitable for providing projection light of a projector includes a heat conductive casing, a phosphor wheel structure and a heat dissipation module. The phosphor wheel structure is disposed in the heat conductive casing. The heat dissipation module includes a channel member and a flow generation device. The channel member is disposed corresponding to the phosphor wheel structure in the heat conductive casing and has a guide channel and a nozzle extending from an outlet of the guide channel and facing a back side of the phosphor wheel structure. The flow generation device is connected to an inlet of the guide channel to generate an airflow flowing into the guide channel and passing through the nozzle for forming an impact flow toward the back side of the phosphor wheel structure.

Abstract: A light source device with a heat dissipation function applied to a projector includes a light source, a heat conduction plate, a flow guide member, and a fluid driving device. The heat conduction plate is disposed on the light source and has a hole structure corresponding to a hot spot region of the light source. The flow guide member has a guide channel corresponding to the hole structure. The guide channel has wide inlet and a narrow outlet. The flow guide member is disposed on the heat conduction plate to make the narrow outlet aligned with the hole structure. The fluid driving device is disposed on the flow guide member and communicated with the wide inlet. The fluid driving device drives fluid to flow from the wide inlet into the guide channel and then pass through the narrow outlet for generating an impact flow toward the hole structure.

Abstract: A transmitter device adapted to be coupled to an image providing device and a receiver device includes first and second conversion units, a wireless module, and a processing unit. The first conversion unit and the second conversion unit are configured to be coupled to the image providing device through an HDMI transmission cable and a Type-C transmission cable, respectively, so as to respectively receive a first video and audio stream and a second video and audio stream provided by the image providing device. The wireless module is connected to the receiver device through wireless communication. The processing unit preferentially selects the first conversion unit to receive a first video and audio signal output by converting the first video and audio stream by the first conversion unit and transmits the first video and audio signal to the receiver device through the wireless module.

Abstract: A video streaming transmission system and a transmitter device are provided. The video streaming transmission system includes a receiver device and a transmitter device. The receiver device is coupled to a display module. The transmitter device is coupled to an image providing device through a transmission line. The transmitter device includes a processing unit, a storage unit, and a wireless communication module. The storage unit is coupled to the processing unit. The wireless communication module is coupled to the processing unit, and is coupled to the receiver device in a wireless communication manner. The processing unit generates virtual extended display identification data and stores them in the storage unit, and provides the virtual extended display identification data to the image providing device through the transmission line, so that the image providing device recognizes multiple virtual displays coupled thereto, and outputs multiple video streams through the transmission line.
