    Abstract: An optical projection module and a fan assembly thereof. A casing comprises at least one heat-dissipation vent. An image projection module is disposed in the casing to create an image. A light source provides light to the image projection module. A fan disposed in the heat-dissipation vent comprises a hub and a plurality of primary blades encircling the hub. Adjacent primary blades overlap in an axial direction. A region formed by the primary blades and the hub blocks a light from transmitting through the heat-dissipation vent.

    Abstract: An axial flow fan with a plurality of segment blades is described. The axial flow fan has a base, a hub and a plurality of blade units. The hub is mounted on, or pivots on, the base and supports the blade units. Each of the blade units is connected to a periphery of the hub and extends radially outward from the base has a plurality of segment-blades. A segment space between the segment blades reforms a boundary layer of fluid passing over the segment blades and reduces the thickness of the boundary layer on the blade surfaces. As a result, the separation between the blade surfaces and fluid is avoided to maintain a laminar flow of the fluid adjacent to the segment blades.

    Abstract: A fan control system. The fan motor is operated normally at not greater than a preset maximum rotation speed. The fan control system has a programmable microcontroller to receive an input voltage and a rotation speed signal corresponding to the actual rotation speed of the fan motor, determining an output signal according to the input voltage and the rotation speed signal, and outputting the output signal; and a fan-driving unit to receive the output signal and adjusting the rotation speed for driving the fan motor according to the output signal. When the rotation speed is lower than a predetermined rotation speed, the rotation speed is in a relation of a first function to the input voltage; when the rotation speed is greater than the predetermined rotation speed, the rotation speed is in a relation of a second function to the input voltage. The first function and the second function are separate mathematical functions, and a first maximum voltage obtained from the maximum rotation speed in the relation of the first function is lower than a second maximum voltage obtained from the maximum rotation speed in the relation of the second function.
