Abstract: A multicolor light mixing module includes a collimator lens disposed on a light-entrance axis and having first and second lens portions, a laser source set including first and second lighting units arranged sequentially for emitting first and second color lights respectively, a reflective unit, a reflective diffusing member and a lens array disposed corresponding to at least one of the first and second lens portions for mixing the first and second color lights. The reflective unit is obliquely disposed on the light-entrance axis and opposite to the first and second lighting units for reflecting the first and second color lights to the first lens portion along the light-entrance axis. The reflective diffusing member is disposed at a side of the collimator lens to homogenize the first and second laser lights and reflect the first and second color lights to the second lens portion along a first light-exit axis.

Abstract: A transmission device for suppressing the glass-fiber effect includes a circuit board and a transmission line. The circuit board includes a plurality of glass fibers, so as to define a fiber pitch. The transmission line is disposed on the circuit board. The transmission line includes a plurality of non-parallel segments. Each of the non-parallel segments of the transmission line has an offset distance with respect to a reference line. The offset distance is longer than or equal to a half of the fiber pitch.

Abstract: An elastic cushion has a cover and an elastic body received inside the cover. The elastic body is made of multiple elastic folded tubes and has multiple gaps inside. Because the gaps are formed inside the elastic body, air can easily pass through the elastic cushion, and the elastic cushion can provide a non-sticky sitting feeling to a user.
