Abstract

A two way mirror system usable for an advertisement device includes a half-mirror having a light transmission function and a reflection function. A logo plate in a shape of an engraving or pattern in relief or intaglio is provided on a front face thereof and a two way screen through which a rear projected image can be viewed from both a front and rear face is provided on a rear face thereof. A single advertising device thus provides a logo advertising using a logo plate and reflected outside light during the day and an image advertisement viewable outside during night time, with inside viewing with double the usual brightness of a reflecting screen.

Claims

1. A two-way mirror system for an advertising device, the device having a front side and a rear side, and which is capable of displaying in bright light a logo pattern from the front side thereof or a rear projected image from both the front side and rear side thereof, comprising:

a half-mirror having a front surface and a rear surface and configured to partially transmit and partially reflect light;

a logo element having a logo pattern provided on the front surface of the half-mirror so that the half-mirror reflects the outline of the logo pattern;

a two-way screen disposed on the rear surface of the half-mirror through which an image projected on the two-way screen is partially transmitted to the rear surface of the half-mirror and from which such image is partially reflected so that the image is doubly reflected, and the image is viewable from the front side and the rear side of the advertising device,

wherein the front side of the advertising device is configured so that during daytime or in bright light the outline of the logo pattern is reflected by the half-mirror and during night time or in low light the image as transmitted through the half-mirror is viewable from the front side of the advertising device through the half-mirror with the outline of the logo pattern, and the rear side of the advertising device is configured so that the double reflected image is viewable on the two-way screen with increased brightness due to the double reflection of the image.

2. The two-way mirror system for an advertising device according to claim 1, wherein the logo pattern is a solid or positive form, so that the half-mirror reflects the peripheral outline of the pattern and a transmitted image surrounds the pattern.
