[0030] In related technologies, there are problems of uneven light in the equipment based on LED light source and light guide plate. For example, in the scene of financial equipment, taking the application of code scanning gun as an example, in order to improve the code scanning effect of the code scanning gun, the brightness during code scanning needs to be improved. The structure of related technologies is usually as follows: multiple LED light sources are distributed at different positions and cooperate with multiple light guide plates to emit light. Because there are multiple LED light sources and light guide plates, the light at each position cannot be uniformly emitted, resulting in poor code scanning effect. Moreover, because multiple LED light sources are distributed at different positions, corresponding light guide plate structures need to be set according to the positions of the LED light sources, so the implementation cost is high.

[0031] In order to solve the above problems, the application discloses the following technical scheme.
