Embodiment Construction

[0008] as attached figure 1 The enclosed room 20 shown is equipped with an electronic window 21 serving as a glazing for illuminating the room 20 . An inventive principle of the present invention is to structurally construct the electronic window 21 as a display screen that has the appearance of a glass window (e.g., a minimum surface area of ​​0.5 m 2 rectangular plane) and (compared to the normal brightness level of a typical display (e.g., 100Cd / m 2 ) compared to) the brightness level associated with glazing (for example, 1000Cd / m 2 to 3000Cd / m 2 ). In one embodiment, electronic window 21 is structurally configured as a substantially bright, self-illuminating display screen (e.g., LED display, LCD display, plasma display, or diffuse reflective display) along all Direction to illuminate the image uniformly, as attached figure 1 As indicated schematically by the solid arrow drawn in . At the same time or as an alternative, the electronic window 21 is structurally config...

Abstract

An electronic window (21) employing an image taking device (22) mounted outside of a room for providing an image of a scenery external to the room. The electronic window (21) further employing a display screen (21) mounted within the room for displaying and illuminating the image at a luminance level for creating a sensation of a glass window being formed in the wall of the room. Alternatively orconcurrently, the display screen (21) can direct an emission of a light beam within the room.

Description

technical field [0001] The present invention relates generally to electronic windows. In particular, the present invention relates to electronic windows for creating the impression of glass windows formed on walls of closed rooms (eg, hospital wards, hotel rooms, indoor shops, workshops, etc.). Background technique [0002] In rooms with no glass windows or glass windows with low external light, the indoor lighting level can be enhanced by artificial light from lamps located in that room. Although this creates enough light for people to carry out activities in the room, the psychological pressure caused by the lack of sufficient nearby windows cannot be relieved by artificial light. [0003] Therefore, the lighting industry is constantly striving to increase the light in dark rooms (for example, hospital wards, hotel rooms, indoor shops, workshops, etc.) to improve the perception of this dark environment background (for example, US Patent US5253000) . To this end, the pre...
