Embodiment
[0043] Surface light emitter 1 of the present invention, as an example, such as figure 1 , 2 As shown, it includes a bendable substrate 11 having wires 12 , a plurality of LED elements 13 arranged substantially regularly on the substrate 11 , and an upper layer film 14 stretched from above the substrate 11 so as to cover the LED elements 13 . Hereinafter, each constituent member will be described.
[0044] First, the substrate 11 will be described. The substrate 11 is a base member on which the LED elements 13 are regularly mounted (mounted), is formed in a film shape or a sheet shape, and various materials having insulation properties and bendability can be applied. Generally speaking, considering the convenience of operation and ease of processing, the substrate 11 is made of plastic (synthetic resin), especially polyethylene terephthalate, which is excellent in heat resistance, light resistance, and mechanical strength. Alcohol ester, polyester, polyamide, polyvinyl chl...

The invention provides a novel surface emitting body incorporating LED elements for which practical functions such as improvement in waterproof property, appearance, and workability are achieved to use it for many other applications than a sign, and an internally illuminated sign assembled with the surface emitting body. The surface emitting body (1) comprises a flexible substrate (11) having electrical wiring (12), a plurality of LED elements (13) disposed on the substrate (11) nearly in a regular manner, and a top film (14) stretched and disposed on the surface of the LED elements (13). When stretching and disposing the top film (14) on the substrate (11), the top film (14) is pasted in close enough with the concavo-convex shape of the surface of the LED elements (13). Specifically, a vacuum application method is used wherein a vacuum is formed between the LED elements (13) and the top film (14) and then the heated top film (14) is attached by pressure on the surface of the LED elements (13).
Description
technical field [0001] The present invention relates to a surface light-emitting body in which a plurality of LED elements are mounted on a bendable substrate, and in particular to a new surface light-emitting body and a surface light-emitting body in which the functions directly related to actual use are further improved, and the practicability as an actual product is greatly improved. An internally illuminated billboard formed by incorporating the surface luminous body. Background technique [0002] As outdoor billboards (inner-illuminated billboards) installed using the wall surfaces of buildings, etc., conventionally, the use of fluorescent lamps has been the mainstream. However, a signboard using a fluorescent lamp requires a large installation space, requires a size (thickness) to accommodate the fluorescent lamp inside, and has a disadvantage of excessive power consumption. Therefore, such an internally-lit signboard tends to use LED elements with low power consumpti...
