Abstract

A depth-perceiving lens module with enhanced heat-dissipating properties comprises a circuit board, an infrared emitter, and an infrared receiver. The circuit board is provided with at least one positioning hole. The infrared emitter is detachably disposed on a side of the circuit board and electrically connected to the circuit board, the infrared emitter comprises a mounting body and an emitting body. The mounting body wraps at least part of the emitting body, at least part of the mounting body is disposed in the positioning hole and fixed to the circuit board. The infrared receiver is detachably disposed on one side of the circuit board and electrically connected to the circuit board, to receive the reflection of the infrared light from the light emitter.
