By the arrangement of the light intensity detecting member, the ambient light intensity can be detected, and the strategic control of the lighting strip 161 can be realized based on the change of the ambient light intensity. For example, when the environment is low-light, the light intensity detection part emits a low-light signal, and the control circuit board 3 controls the lighting lamp belt 161 to be turned on or turned on so as to cope with the condition of insufficient light on the reticle; conversely, when the environment is enough, the illuminating lamp belt 161 can be turned off or adjusted to the atmosphere effect, so that the electric energy is saved, and the use experience is improved.
