Abstract:
The present invention relates to an entrance guard device with light-uniformization structure, comprising: a housing, a main controlling module, a keypress module, a display module, a doorbell module, and an image capture module, wherein the image capture module consists of an image capture device accommodating body, a light-emitting assembly, an image capture device, a light-uniformization member, and a lens. In the present invention, the light-uniformization member is disposed at the front of a plurality of light-emitting chips of the light-emitting assembly, such that the light emitted by the light-emitting chips is able to enter the light-uniformization member, and then the light would be uniformly emitted by the light-uniformization member after the light are refracted; Therefore, the uniform light may shine on people face for making an image capture device of the image capture module capture the facial feature of people completely and clearly.
