<P>PROBLEM TO BE SOLVED: To reduce manufacturing cost in a light-emitting apparatus by facilitating the arrangement of light-emitting devices, and to improve visibility of a character or the like by securing a light emission volume necessary for a luminously-displayed character or the like to be visually seen clearly from its lower side at night even when the light-emitting apparatus is mounted at a high place such as a rooftop of a building and an upper side of an outside wall. <P>SOLUTION: A belt-like flexible substrate 31 is arranged in a case 2 having a predetermined shape in front view to be orthogonal to the front surface portion 21 thereof, and LED packages 32a are arranged in parallel on the flexible substrate. Accordingly, the LED packages 32a can be arranged at desired positions by only deforming the flexible substrate 31, thereby facilitating its arrangement and improving efficiency in assembling work. Moreover, not only are the LED packages 32a arranged conventionally in only one row in a length direction of a sidewall of the flexible substrate, but a plurality of LED packages 32a are arranged in parallel in the length direction and width direction of mounting surfaces 31a and 32b, thereby securing the light emission volume. <P>COPYRIGHT: (C)2009,JPO&INPIT |
