摘要： The disclosure provides a projection device and a parameter adjustment method thereof. An environment detection value is received from a detection module through a control chip, wherein the environment detection value is at least one of an environment illuminance value, a volume load value and an environment volume value. Then, the environment detection value is compared with a reference range to obtain a corresponding environment mode. Furthermore, a rotation speed of a fan module is adjusted according to an environment load value corresponding to the environment mode. The projection device and the parameter adjustment method thereof provided by the invention make the illuminance and noise output of the projection device more suitable for the operation condition.

摘要： A near-eye display device includes a main frame, a temple, an optical engine module, a first heat transfer plate, and a second heat transfer plate. The temple is pivotally connected to the main frame, and the optical engine module is disposed in the main frame. The first heat transfer plate is disposed in the main frame and connected to the optical engine module. The second heat transfer plate is disposed in the temple. The temple is adapted to be rotated relative to the main frame and switched between a folded state and an unfolded state. When the temple is in the folded state, the second heat transfer plate and the first heat transfer plate are separated from each other. When the temple is in the unfolded state, the second heat transfer plate is in contact with the first heat transfer plate.

摘要： A projection apparatus includes a frame body, an optical engine module disposed in the frame body and including at least one light source and a light valve, a projection lens, and a first heat dissipation module. The light source provides an illumination light beam. The light valve located in a transmission path of the illumination light beam converts the illumination light beam into an image light beam. The projection lens located in a transmission path of the image light beam projects the image light beam. The first heat dissipation module is disposed on the frame body and contacts at least one of the light source and the light valve. The frame body and the first heat dissipation module together form at least part of a housing of the projection apparatus. A thermal conductivity coefficient of the frame body is less than that of the first heat dissipation module.
