Description

The present invention applies light from an LED (light-emitting diode) light source to an end face of a transparent resin optical fiber, passes the light through the optical fiber, and shines the entire side surface. The present invention relates to a building material product having a function as a combination of a security light or a guide light.

Conventionally, a light is turned on to check the position of a dark foot or a handrail in a room, a staircase, or the like in a public facility such as a movie theater aisle, building, store, or hospital. However, in the event of a power failure or the like, the guide light as an emergency light is lit only in the direction with a pattern such as an arrow or an emergency exit. However, in this method, it may be difficult to reach the exit in an emergency.

In a room or a passage of a movie theater, a building, a store, a hospital, or the like, a baseboard, a handrail, or the like, which is a plate material to be attached to a portion of a wall surface in contact with the floor, is generally installed. If the light from the energy-saving LED light source can be continuously combined with the building material products such as the baseboard and the handrail, it can have a function as a safety light or a guide light.

Means for the Invention to Solve

Therefore, the optical properties and transparency are excellent, but the strength is weak, and a fragile transparent fluororesin is used as a core of 1 to 5 mmφ and extruded into a long round bar. Two-color molding, that is, co-extrusion processing of a transparent vinyl chloride resin layer having a thin film thickness of about 1.0 mm, that is, a two-layer film having excellent strength and transparency of about 2-6 mmφ. A round bar shape is formed. When the LED light is turned on from the end face of a transparent round bar shaped optical fiber with a diameter of 2 to 6 mm, which has a function as an optical fiber, this round bar passes through the optical fiber and reaches the other end face about 5 m ahead. Not only does the light reach, but the entire side surface of the optical fiber shines brightly. In particular, when LED light is used as a light source of red, green, and blue, which are the three primary colors of light, a distinct colored transparent light forms a state in which the entire optical fiber emits light.

For example, this optical fiber with a diameter of 3 mmφ is affixed to the surface or built in parallel with building materials such as baseboards, handrails, stair steps, floor and wall surface wire protection covers, etc. Is converted to direct current with an AC adapter, the LED is turned on, and when the light from the LED light source is applied to the end face of an optical fiber built in a surface such as a baseboard, the LED light passes through the optical fiber and is about 5 m away. Since one end surface is brightly shining and the entire side surface of the optical fiber is brightly shining, a building material product such as a baseboard can have a function as a security light or a guide light. In particular, the baseboard in which the optical fiber connected to the LED light source of the three primary colors of red, green, and blue light is embedded in the surface of the building material product or in the lateral groove is very similar to the optical fiber on the plate material in contact with the floor of the constructed wall. It emits a conspicuous transparent color and forms a state that functions as a security light or guide light.

Effect of device

For example, when a building where many people gather, such as a movie theater or a department store, has a power outage, currently only the direction of the emergency exit pattern is lit, but it may be confusing because the way on the way is unknown. However, according to the present invention, even when a power failure occurs when an optical fiber is emitted by the light of an LED light source with an emergency battery added to the AC adapter and the baseboard is installed in a portion in contact with the floor of the wall, When the emergency battery is activated and the optical fiber emits light and passes through the passage along the light of the optical fiber, the trajectory of the escape route can be secured, and it is possible to go outside through the stairs.

In FIG. 3, a baseboard 6 having a width of 55 mm × 3 scales (915 mm) length × 5 mm thickness is connected to each other by a connection unit. For example, five skirting boards are connected, and an LED unit 4 in which AC electricity input from a commercial power source 1 through a plug 2 is converted into DC via an AC adapter 3 is connected to one end of the skirting board. The total length of light emitted from the LED side end face of the optical fiber 7 embedded in a groove on the baseboard surface of about 4.6 m, and the other end face is emitted by 5 baseboards. When the unit is installed in parallel with a portion of the wall surface in contact with the floor, a long light emitting device in which the entire building material product with the LED light source and the optical fiber is provided with a function as a security light or a guide light can be formed. The baseboard with an optical fiber according to the present invention is soft and has a characteristic that it can be bent into a curved surface, and a product corresponding to a curved surface such as a spiral staircase can be formed flexibly.

In addition, the whole unit of FIG. 3 is united, and an LED unit with an emergency battery added to the AC adapter is incorporated as shown in FIG. If it is extended further, in the event of an emergency such as a power failure, it is possible to form a long light emitting building material product with an LED light source and an optical fiber having a function as a guide light. The length of this product can be freely selected according to the application and location.

This long light-emitting building material product can be used not only in public facilities such as movie theaters, department stores, stores, hospitals, and subways, but also in apartment buildings and ordinary houses.
