It is well-known that the above-mentioned conventional blinking warning indicator which employs an LED which can be used for a long period of time without replacing the light bulb as a light source is provided on the market. The configuration shown in FIG. 6 shows the configuration of Japanese Utility Model Application Publication No. 1995-49683. The base 71 has a side wall 74 that rises forward and a projection 72 formed in the center, and an annular bottom 73 formed from the side wall 74 has a large number of square pyramid-shaped irregularities formed on its back surface (diamond cut). Are mounted. On the back side of the light generator 75, light-emitting diodes (hereinafter referred to as LEDs) 76,... Are inserted and fixed in twelve small holes formed in a ring and radially. A part of the light beam emitted from the LED 76 travels straight forward as it is, and the remainder is diffusely reflected and refracted inside the light generator 75 and radiated forward, so that a complicated and varied light beam is radiated.
[0004]
In the above-described conventional example, the light emitting portion in the blinking warning display is the LED 76 of the light source, but the irradiating portion is the LED 76 and the light generator 75 to which the LED 76 is attached and diffuses and diffuses the light emission. . For the area of the light generator 75, its diameter maximizes the width of the bottom forming an annulus on the base 71.
[0005]
Since the light generator 75 is circular, the maximum part of the irradiation light is on the center line indicating the diameter of the generator 75, and when arranged in an annular shape as described above, the light generator looks between adjacent light generators. On the line connecting the centers of the light generators 75, the distance is narrow, however, the distance between the light generators increases from the line toward the outer periphery of the base 71, and becomes maximum at the outer periphery. As a result, the portion that emits light as the blinking warning indicator has a maximum line passing through the center of the light generator 75, and the portion that does not emit light toward the outer peripheral portion from that line can be increased. The irradiation light has a maximum at a circumferential line connecting the centers of the light generators 75, but becomes weaker toward the outer peripheral side, and as a result, the apparent irradiation area is smaller than the size of the base. .
[0006]
Further, in order to irradiate light from the entire irradiation surface of the light generator 75, a considerable amount of LED is required, and it becomes necessary to use a large amount of LED, which is one of the factors which makes the blinking warning display expensive. Was.
