Optic control module
View Patent ↗An optic control module includes a housing, a light source, an optic lens body, a detector, and a control circuit. The housing contains therein a circuit board in electrical connection with a plurality of terminal pins. The light source is mounted on the circuit board and is electrical connection with the terminal pins for providing light. The light, after transmitting, in sequence, through a first optic curved surface, a first inclined surface, and a second optic curved surface of the optic lens body, leave the optic lens body and is then reflected by an operative body located above the optic lens body to travel through a third recess and a third optic curved surface of the optic lens body to get back to the detector. The detector is arranged on the circuit board of the housing at a location below a second protrusion of the optic lens body to receive and process the reflected light. The control circuit is formed on the circuit board to receive a signal transmitted from the detector to control the operation of the optic control module. As such, a modularized optic control module is provided.
1. An optic control module, comprising:
a housing in which a circuit board is contained, the housing comprising a plurality of terminal pins that is in electrical connection with the circuit board;
a light source mounted on the circuit board inside the housing, the light source being in electrical connection with the terminal pins of the housing to selectively provide light;
an optic lens body mounted to a top of the housing, the optic lens body comprising a first protrusion that forms a first optic curved surface, a first recess formed above the first protrusion, a first inclined surface formed inside the first recess, a second recess formed on a right side of the first recess and forming a second optic curved surface, a fourth recess being formed on a bottom of the optic lens body at a location below and between the first protrusion and the second recess, the fourth recess forming a second inclined surface, the optic lens body further forming a third recess, the bottom of the optic lens body forming a fifth recess below the third recess, the fifth recess forming therein a second protrusion that forms a third optic curved surface;
a detector mounted on the circuit board at a location below the second protrusion of the optic lens body for receiving and processing light; and
a control circuit formed on the circuit board of the housing for receiving a signal from the detector to control operation of the optic control module, whereby a modularized optic control module is provided.
2. The optic control module as claimed in claim 1 , wherein the detector comprises a complementary metal oxide semiconductor device.
