器用照明室に係る発明である。Summary of the gist> The present invention is a lighting system in which various electronic display devices having cathode ray tubes such as industrial televisions, word processors, personal computers, and oscilloscopes are operated under illumination light caused by ambient light from electric lights or windows. This invention relates to a room, and in particular, the surface of a cathode ray tube when facing the cathode ray tube to view the displayed content,
Alternatively, one or both of the viewing glasses can be given polarization by pasting a polarizing sheet in one direction, etc., and the other side's disturbance light source, such as a light or window, can be polarized in a direction perpendicular to this. This invention relates to an illumination room for an electronic display device that provides polarization in the direction of the display so that only the information content displayed on the cathode ray tube can be clearly viewed without being interfered with by reflected light due to ambient light. .

As is well known, the display surface of device A has an extremely high reflectance.
Therefore, flickering reflections from ambient light from indoor lights and windows not only make it difficult for the operator or viewer to see what is displayed on the cathode ray tube, but in extreme cases, information may be misunderstood or a type of visual disturbance may occur. There are defects that can even lead to occupational diseases.

ｉ’Ｘすることが出来ないという難点がある。To deal with this, for example, a light-transmitting thin film such as a flexible sheet has been developed in which a number of light-shielding films are provided at predetermined angles. There is also a method that has a disturbance light blocking effect that reflects disturbance light from lights and windows to prevent it from entering the eyes, but with this type of technology, the information displayed on the cathode ray tube is reflected to the person sitting directly in front of the cathode ray tube. Although there is an advantage in being able to see the CRT without being obstructed by light, do assistants, instructors, etc. who are seated together and viewing the CRT from an angle see the CRT display information?

The problem is that it is not possible to do i'X.

The interior of the room, where the 8-bars are arranged, should be designed so that light from electric lights and windows does not interfere with office work such as checking documents, filling out information, and holding meetings. Windows, electric lights, etc. are coated with a polarizing sheet that has polarization in one direction, and on the other hand, the surface of the cathode ray tube of O-A equipment is coated with polarized light that has a polarization in a direction different from that of the polarizing film of windows, electric lights, etc. Attach the sheet everywhere,
By wearing polarized glasses, you can completely prevent flickering caused by the reflection of ambient light from windows and electric lights on the surface of the CRT, allowing you to see only the information light from the CRT, allowing you to see the information displayed on the CRT smoothly and reliably. Technical measures have been taken to make it possible to do so.
〈実施例〉

In an illumination room that has O-A equipment such as word processors and oscillographs arranged with cathode ray tubes as electronic displays, the illumination light from external lights such as windows and electric lights is polarized in one direction. Alternatively, by imparting polarized light having the other direction to glasses or the like, the worker will not be able to see the reflected light from external disturbances such as from windows or electric lights on the cathode ray tube. Since you can reliably see only the information that is visible to you, you can ensure that you are operating in a stable condition without causing eye strain or occupational diseases.
- The excellent effect of being able to perform processing operations on the A device is achieved.
