Abstract: A light guide device is provided. The light guide device includes a light guide member and a reflective member. The light guide member includes a junction surface, a first light incident member, a second light incident member, a contact surface, and a reflective curve surface. The reflective member includes a reflective surface adapted to the reflective curved surface and the contact surface of the light guide member. The first light receiving member and the second light receiving member respectively aligned to a first light-emitting element and a second light-emitting element, and are used to receive light emitted by the first light-emitting element and the second light-emitting element and guide the received light out.

Abstract: A multifunction key includes a key member, a conductive member, and a circuit baseboard. A portion of the key member extends out from a shell of an electronic device; the conductive member is fixed on a bottom of the key member. The conductive member includes a first protrusion member and a second protrusion member. One surface of the circuit baseboard includes a conductive layer and a resistance layer respectively contacting the first and the second protrusion member. Another surface of the circuit baseboard includes a first and second conductive terminal respectively connected to the conductive layer and the resistance layer. The conductive layer, resistance layer, first and second conductive terminal, conductive member, and an internal circuit of the electronic device form a circuit loop. When the key member moves, a resistance value of the resistance layer within in the circuit loop is changed and produces a corresponding key command.

Abstract: A manufacturing method for manufacturing a protective case, includes steps: a reflective film is prepared; a first filter film, a second filter film, and a third filter film of a color filter film, and then a decorative film are laminated on the reflective film in sequence to form a multilayer film structure; and a plurality of couples of relative positions of opposite surfaces of the multilayer film structure are processed via a bidirectional processing machine, thereby forming a plurality of light transmission openings penetrating the reflective film and the decorative film and further penetrating at least one or zero of first filter film, the second filter film, and the third filter film. A rear plate including the plurality of light transmission openings, the reflective film, the color filter film, and the decorative film is formed accordingly.

Abstract: An LED illuminating device comprises a housing with a base plate, a prism sheet and a circuit board. The prism sheet is mounted in the housing and comprises a number of V-shaped micro-grooves formed thereon along three directions intersecting with each other. The circuit board is fixed on the base plate, wherein a plurality of LED units are arranged on the circuit board, each two adjacent LED units are spaced a preset distance apart from each other and emit light of different colors. Six virtual mixed light sources are formed by reflection of the prism sheet to the circuit board when the light emitted by an LED unit mixes with light emitted from adjacent LED units on the circuit board. Each of the virtual mixed light sources has a color different from the colors of the light emitted from the LED units.

Abstract: An LED illuminating device comprises a housing with a base plate, a prism sheet and a circuit board. The prism sheet is mounted in the housing and comprises a number of V-shaped micro-grooves formed along two directions intersecting with each other. A plurality of LED units are arranged on the circuit board in groups, each group comprises four LED units, the four LED units totally emitting light of three colors. Two adjacent groups share a LED unit. Four virtual mixed light sources are formed by reflection of the prism sheet to the circuit board. Each of the virtual mixed light sources forms a desired color different from the colors of the light emitted from the LED units.
