Abstract: The present pertains to an optical module including an optical shell, a plurality of first light-emitting diodes, a plurality of light guide plates, and a plurality of second light-emitting diodes. The optical shell includes a plurality of recessed portions and a flat portion surrounding the recessed portions. One of the first light-emitting diodes is disposed in the recessed portions. Each of the light guide plates has a top surface and a sidewall, and the top surface of the light guide plate is substantially at the same level as the flat portion of the optical shell. One of the second light-emitting diodes is disposed below the top surface of the light guide plates and is adjacent to the sidewall of the light guide plates.

Abstract: A package structure of a light-emitting element includes a shell, a first conductive path, a second conductive path, a light-emitting device, a cover, a first light-transmitting sensing electrode, and a second light-transmitting sensing electrode. The shell has a top surface and a bottom surface, and the top surface is recessed toward the bottom surface to form an accommodating space. Each of the first and second conductive paths extends from the top surface to the bottom surface. The light-emitting device is disposed in the accommodating space. The cover is disposed over the shell. The first and second light-transmitting sensing electrodes are disposed on the same surface of the cover, and a capacitance is formed between the first and second light-transmitting sensing electrodes. The first and second light-transmitting sensing electrodes are electrically connected to the first and second conductive paths, respectively.
