  • Patent number: 9976898
    Abstract: An optical sensing module capable of providing a multi-directional optical sensing function teaches that the optical sensing module can be fixed on a circuit board via a bridging medium. The optical sensing module includes a supporter, a photosensitive component and a connecting component. The supporter includes a base and several lateral portions. The lateral portions are bent from edges of the base to form an accommodating space. The photosensitive component is disposed inside the accommodating space to receive an optical signal passing into an opening of the accommodating space. The connecting component is disposed on the supporter and includes a conductive terminal. The supporter is connected with the bridging material via the conductive terminal to stand on the circuit board by one of a plurality of sensing directions.
