Abstract: The present invention provides a heat dissipating assembly for a heat element comprising a board on which at least a heat source, heat conductive layer and a heat dissipating sheet are set. The heat conductive layer is formed between the heat dissipating sheet and the board by squeeze bonding, thermal fusion or ultrasonic fusion. The heat conductive layer is made up of a material possessing the properties of quick heat conduction and compressive flexibility. While the heat conductive layer is adhered by squeeze bonding, thermal fusion or ultrasonic fusion, heat is conducted by its entire surface. The present invention is able to raise the heat dissipating efficacy and draw out the heat from the heat source quickly, therefore, increases the brightness and durability of the light source.

Abstract: The present invention discloses a package structure of a stack-type light-sensing element and a package method thereof, wherein firstly, a substrate is provided; next, a signal-processing IC chip and a light-sensing chip are sequentially stacked above the substrate in bottom-up sequence; next, lead lines are used to electrically connect the substrate with the signal-processing IC chip and the light-sensing chip in order to form a unitary light-sensing element. The present invention has the advantages that light-sensor signals are directly processed and then output to a display device, and that the volume of a light-sensing element can be reduced to such an extent that it can be easily applied to miniature electronic products. In contrast with the conventional light-sensing element needing massive volume of electronic circuits to process signal and also needing minute and complicated assemblage, the present invention has superior novelty and futurity.

Abstract: An improved structure of a laser indicator includes an outer tube, a cover cap, a focus adjusting device, an optical lens, and a circuit board having a laser diode disposed thereon. The outer tube and the cover cap are joined to form a rod-shaped indicator housing.
