The positioning groove of one heat dissipation fin is aligned with the positioning groove of another heat dissipation fin to form a positioning perforation. The heat pipe is clamped between the heat dissipation fins and passes through the positioning perforation along an extension axis. On a cross section perpendicular to the extension axis, a cross-sectional width and a cross-sectional thickness of the heat pipe are respectively D1 and D2, where D1 is greater than or equal to D2. A projection device is also provided. | 2021-08-19 |
20210255532 | ILLUMINATION SYSTEM, ILLUMINATION CONTROL METHOD AND PROJECTION APPARATUS - An illumination system including a first laser light source, a second laser light source, and a wavelength conversion module is provided. The first laser light source provides a first laser light beam in a first time interval and a third time interval.
