It can be understood that the position where the colloid is disposed may be a position directly facing the light guide body. For example, colloid can be set at the preset mark of the infrared lamp light guide module.

It should be noted that the embodiment of the present application does not limit the specific sequence of the above-mentioned steps, and can be performed according to the above-mentioned sequence. The assembly can be carried out in a sequence other than the above sequence, so that the emitting end of the infrared lamp is directly facing the light guide body.

The method for assembling the infrared light guide module provided in the embodiment of the present application can effectively shorten the dimensional tolerance chain between the infrared lamp and the light guide column and reduce the tolerance during the assembly stage, thereby reducing the distance between the infrared lamp and the light guide column after assembly. The eccentric value between them ensures the infrared emission power.

It should be noted that the electronic devices in the embodiments of the present application may include mobile electronic devices and non-mobile electronic devices. Exemplarily, the mobile electronic device may be a mobile terminal device, such as a mobile phone, a tablet computer, a notebook computer, a palmtop computer, a vehicle electronic device, a wearable device, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook or a personal Digital assistant (personal digital assistant, PDA), etc., non-mobile electronic equipment may be non-mobile terminal equipment, such as server, network attached storage (network attached storage, NAS), personal computer (personal computer, PC), etc., the embodiment of the present application Not specifically limited.
