All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, in one embodiment, the optical interaction laser pen comprises a housing 110 and a circuit board 120 accommodated in the housing 110, a button 130 is arranged on the housing 130, one end of the button 130 extends onto the circuit board 120 and is used for triggering a circuit on the circuit board 120, the other end of the button is exposed outside the housing 110, and the button is arranged on the side surface of the housing near the front part of the housing so as to be convenient for pressing by fingers. The circuit board 120 is provided with a power management chip 121 and a lamp bead 122 which are electrically connected, the lamp bead 122 is a light emitting diode, a light emitting end extends out of the housing 110, the power management chip 121 is used for identifying the continuous pressing times of the button 130, and different voltages are controlled and output according to different continuous pressing times so as to control the lamp bead 122 to emit light with different colors. When the red light or the blue light is emitted, the LED display device can be used for indicating objects, and is convenient for reporting, teaching and viewing. When purple light is emitted, the device can be used for detecting paper money. When white light is emitted, the light source can be used for temporary illumination, and the functions of the laser pen are enriched.

In this embodiment, a main control chip 124 is further disposed on the circuit board 120, and the main control chip 124 is electrically connected with the power management chip, and is used for binding an optical interaction application account in the optical interaction terminal, and controlling the power management chip 121 to drive the lamp beads 122 to emit optical signals, so as to implement optical interaction. Specifically, the circuit board is further provided with a communication module 123, and the communication module 123 is electrically connected with the main control chip 124 and is used for establishing connection with the optical interactive terminal so as to complete binding with the optical interactive application account.
