Visual doorbell entrance machine light supplement lamp and device

Abstract

The embodiment of the invention discloses a visual doorbell entrance machine light supplement lamp and device; the lenses comprise a first lens made of optically denser medium and close to the lamp and a second lens made of optically thinner medium and close to the door outer side; the lamp light enters the optically thinner medium from the optically denser medium, and enters the air from the optically thinner medium, thus forming two refractions, diffusing the light, enlarging the visual angle, and solving the technical problems of dazzling concentration light and small visual angle caused by directly using an LED lamp and a transparent light block lens for light supplement. The visual doorbell entrance machine light supplement lamp comprises the lamp, and lenses symmetrically arranged up and down outside the lamp; the lenses comprise the first lens made of optically denser medium and close to the lamp and the second lens made of optically thinner medium and close to the door outer side; the first and second lenses are tightly attached, and the contact surface is a non-vertical contact surface.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a supplementary light and a device for a visual doorbell door station. Background technique [0002] With the development of society, video doorbells are more and more widely used in communities. [0003] Since the video doorbell VTO is in the night state, night vision supplementary light is required, such as figure 1 As shown, most of the VTOs currently on the market are implemented directly by using LED lights and transparent light-blocking lenses. This solution will cause technical problems such as concentrated light and glare and a small viewing angle. Contents of the invention [0004] The embodiment of the present invention discloses a supplementary light and device for a video doorbell door machine. The lens is designed as a first lens made of an optically dense medium close to the light and a second lens made of an optically sparse medium close to the door. The second lens, ...
