Description

  The present invention relates to a hybrid multi-panel that combines lightning and light storage. The present invention is 1). Installed on pillars and walls of station buildings and their underground communication passages, office underground shopping streets and their communication passages, airport terminals, tower buildings, large commercial facilities, general hospitals, stadium gates, movie theaters, amusement facilities, and various public facilities and parks Internally illuminated signboard panels, internally illuminated signboard panels, etc., operate as unpowered emergency lights in the event of a power failure, and are effective for disaster prevention as one of the evacuation guidance items, 2). Indirect lighting panels such as elevator ceiling lighting panels and interior panels, escalator sidewall panels, etc., operate as no-power emergency lights during power outages, and as indirect lighting panel structures that are effective for disaster prevention as one of the evacuation guidance items The present invention relates to a lightning / light storage hybrid multi-panel.

  In urban areas, the communication path between the station building and the underground shopping area, and the underground shopping area and the neighboring building basement are closely developed, so the convenience is extremely high, but the underground area landscapes of these underground shopping malls and their communication paths are similar. Therefore, there are not a few people who make a mistake in the direction. Therefore, it is difficult to guide evacuation smoothly when encountering a disaster power outage in the underground area, and the problem of the expansion of secondary disasters has become serious due to the frequent occurrence of panic due to a sense of blockage in the underground area.

  A lot of internally-lit signboards have been installed on the walls of underground shopping streets and communication passages since ancient times. Since these internally illuminated signboards are also useful as lighting, it is desirable that the internally illuminated signboards can be used as emergency lights during power outages. Therefore, by incorporating a special layer using a phosphorescent material into the structure of the internally illuminated signboard, an advertisement is displayed as an internally illuminated signboard during normal times, and the non-powered illumination by the phosphorescent light emission of the special layer is activated during power outages. Various evacuation guidance systems have been proposed. The present applicants have previously proposed a heterogeneous display structure (Patent Document 1) that functions as a signboard during normal times and can store and emit evacuation guidance messages during power outages. This display structure can surely display the message of evacuation guidance by phosphorescent emission in the dark, but because of the contrast configuration of the light emitting part and the non-light emitting part, the emergency light function with sufficient light quantity cannot be expressed, Further, since the light emitting portion is a light green color derived from a phosphorescent pigment, there is a difficulty in lacking harmony in appearance by interfering with colors such as advertisements and photographs applied to the display structure.

  Also, it functions as a conventional outdoor illumination membrane material, and in the event of a power outage due to a disaster, a luminous phosphor-containing resin is used as an outdoor illumination membrane material that emits light by itself and serves as a mark for evacuation passages and evacuation sites. There is a proposal of a laminated structure (Patent Document 2) in which a white and semi-hiding resin layer is provided on a layer. This laminated structure certainly satisfies both the whiteness of the surface during normal use and the luminescence during power outages, and can be a landmark in the dark, but in order to make the light green hued phosphorescent resin-containing resin layer inconspicuous In addition, the provision of a semi-concealing resin layer on the phosphorescent resin-containing resin layer causes the phosphorescent emission emitted from the phosphorescent phosphor-containing resin layer to be attenuated by the semi-concealing resin layer. Met. Therefore, it is usually used as a light-emitting panel, emits no power when a power failure occurs due to a disaster, etc., and conceals the light green color derived from a phosphorescent fluorescent material during normal use, while providing an emergency light function with high light intensity. A phosphorescent hybrid multi-panel was desired.
